The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 197% of the average value of its portfolio.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your cost of investing in the Fund would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its investment objective by investing primarily in common and preferred stocks. The Fund may also invest in equity investment companies (“underlying funds”), which include domestic and foreign mutual funds, which may invest in emerging markets, as well as in exchange traded funds (“ETFs”), closed-end funds, and unit investment trusts. The Fund may invest in index funds and index-based investments.

The Fund may also invest directly in derivatives, such as options and futures contracts, or in underlying funds investing in futures contracts and options on futures contracts. These investments may be used, for example, in an effort to earn extra income, to provide adequate liquidity, to adjust exposure to individual securities or markets, to protect all or a portion of the Fund’s portfolio from a decline in value, or to maintain a fully-invested position in equity securities.

When selecting investments for the Fund the Adviser continually evaluates style, market capitalization, sector rotation, and international positions by utilizing a series of quantitative models to perform fundamental and technical analysis in order to identify opportunities that have the best attributes for outperformance. Individual equity selection is driven by the Adviser’s quantitative model that evaluates securities based on exposure to value, quality, momentum, and sentiment characteristics:

	●	Value is a measure of the relative value of a company using metrics such as revenue, cash flow, and income;
	●	Quality is a measure of the financial performance of a company, typically measured by the stability of its earnings and cash flows, along with the strength of its balance sheet;
	●	Momentum is a measure of the rate of change in the price of securities over time; and
	●	Sentiment is a measure of the prevailing attitudes of investors related to anticipated price movements in the market.

There are no investment limitations on market capitalization range or geographic region The Adviser selects securities that the Adviser believes represent above average market potential relative to market risk. The Adviser may focus on stocks or underlying funds investing in stocks that are newer and/or smaller capitalization companies.

The Fund utilizes several defensive tactics to reduce or eliminate its position in common stocks and underlying equity funds in order to attempt to reduce the risk of loss when the Adviser’s quantitative models and evaluation indicate that the risks of the stock market may be greater than the potential rewards. Utilizing its unconstrained tactical strategy, the Fund may invest up to 100% of its net assets in fixed income securities of any maturity and of any credit rating (including unrated and high yield fixed income securities, commonly known as “junk bonds”) and cash equivalent securities. The Fund may invest in underlying fixed income funds that invest in domestic and foreign fixed income securities, ETFs, closed-end funds, and unit investment trusts. The Fund may also buy or sell derivatives, including domestic or international stock index futures or options and option spreads on index future contracts. An option spread is a strategy where the Fund buys two different options on an index, but with different prices or expirations, in order to hedge against declines in equity market value. The use of these techniques may not protect against market declines and may limit the Fund’s participation in market gains, particularly in volatile market conditions.

Other than as set forth in the SAI, the investment policies and limitations of the Fund are not fundamental and may be changed by the Board of Trustees of the Meeder Funds without shareholder approval.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

All investments carry a certain amount of risk and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Loss of money is a risk of investing in a mutual fund. All of the risks listed below are significant to the Fund, regardless of the order in which they appear.

Common Stock Risk. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

Credit Risk. All debt securities are subject to the risk that the issuer or guarantor of the debt security may not make principal or interest payments as they become due, or default entirely on its obligations. The value and liquidity of an issuer’s debt securities will typically decline if the market perceives a deterioration in the creditworthiness of that issuer. In addition, insured debt securities have the credit risk of the insurer in addition to the underlying credit risk of the debt security being insured.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Fixed Income Risk. The Fund is subject to the general risks and considerations associated with investing in debt securities, including the risk that an issuer will fail to make timely payments of principal, or interest, or default on its obligations. Lower-rated securities in which the Fund may invest may be more volatile and may decline more in price in response to negative issuer developments or macroeconomic news than higher rated securities. In addition, as interest rates rise, the Fund’s fixed income investments will typically lose value.

Foreign Investment Risk. Investments in foreign issuers, whether directly or indirectly, involve additional risks different from those associated with investments in U.S. issuers. There may be limited information available to investors, and foreign issuers may not be subject to uniform accounting, auditing and financial standards like those applicable to U.S. issuers. Different accounting, corporate governance, regulatory, and market systems may cause foreign investments to be more volatile. Additionally, currency fluctuations my affect the value of foreign investments.

●

Emerging Markets Risk. Investing in emerging markets involves magnifies the risks inherent in foreign investments. These risks include exposure to economic structures that are generally less diverse and mature than found in developed markets, limited availability of reliable information material to an investment decision, exposure to political systems that may be less stability than those of developed countries, and greater exposure to foreign currency fluctuations. The market for the securities of issuers in emerging market typically is small, and a low or nonexistent trading volume in those securities may result in a lack of liquidity and price volatility.

High Yield Risk. The Fund may purchase fixed income securities rated below the investment grade category (non-investment grade bond, speculative grade, or junk bond). Securities in this rating category are considered speculative. Changes in economic conditions or other circumstances may have a greater effect on the ability of issuers of these securities to make principal and interest payments than they do on issuers of investment grade securities. Therefore, fixed income securities in this category may have greater price fluctuations and have a higher risk of default than investment grade securities.

Interest Rate Risk. Fixed income securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund’s fixed income investments will generally decline. On the other hand, if rates fall, the value of the fixed income investments generally increases. Your investment will decline in value if the value of the Fund’s investments decreases. The market value of debt securities (including U.S. government securities) with longer maturities is likely to respond to changes in interest rates to a greater degree than the market value of fixed income securities with shorter maturities.

Investment Company Risk. Because the Fund may invest in underlying mutual funds and unit investment trusts, the value of your investment also will fluctuate in response to the performance of the underlying funds. In addition, you will indirectly bear fees and expenses charged by the underlying investment companies in which the Fund invests in addition to the Fund’s direct fees and expenses. You also may receive taxable capital gains distributions to a greater extent than would be the case if you invested directly in the underlying funds.

●

Closed-end Fund Risk. Closed-end funds involve investment risks different from those associated with other investment companies. Shares of closed-end funds frequently trade at either a premium or discount relative to the value of the securities held by the closed-end fund. Closed-end funds may trade infrequently and with small volume, which may make it hard for the Fund to buy and sell shares. Many closed-end funds also utilize leverage, which can expose the Fund to greater risk of significant changes in the closed-end funds’ share prices and will require payment of interest or dividend expenses, reducing the closed-end fund’s overall return.

●

Exchange Traded Fund and Index Fund Risk. ETFs and index funds will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. In addition, the ETFs and index funds will incur expenses not incurred by their applicable indices. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ability of the ETFs and index funds to track their applicable indices. The Fund also will incur brokerage costs when it purchases ETFs. An ETF may trade at a discount to its net asset value.

Issuer Cybersecurity Risk. Issuers of securities in which the Fund invests, counterparties with which Fund engages in transactions, exchange and other financial market operators, banks, brokers, dealers and other financial institutions may experience cybersecurity breaches. Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; ransomware; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. These breaches may result in harmful disruptions to their operations and may negatively impact the financial condition for the municipal issuer, counterparty or other market participant. The Fund and its shareholders could be negatively impacted as a result.

Liquidity Risk. Reduced liquidity affecting an individual security, or an entire market may have an adverse impact on market price and the Fund’s ability to sell particular securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets. The current novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, has had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

Market Capitalization Risk. Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the Fund’s performance could be impacted.

●

Large-Capitalization Risk. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

●

Mid-Capitalization Risk. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

●

Small-Capitalization Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the Adviser relies on quantitative models and information and data supplied by third parties (“Models and Data”). These Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investment risks.When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Many of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the quantitative models used by the Adviser will not be successful in selecting companies for investment or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.

Momentum Style Risk. Investing in or having exposure to securities with positive momentum entails investing in securities that have had positive recent relative performance. These securities may be more volatile than a broad cross-section of securities. In addition, there may be periods during which the investment performance of the Fund while using a momentum strategy may suffer.

Options Strategy Risk. The Fund may buy and sell options as a defensive tactic, to earn income, or to adjust exposure to the markets. As the buyer of a call or put option, the Fund may lose the entire premium paid for the option if the value of the security underlying the option does not rise above the call strike price, or fall below the put strike price, which means the option will expire worthless. As a seller (writer) of a call or put option, the Fund will tend to lose money if the value of the underlying security rises above the call strike price or falls below the put strike price. The Fund’s losses are potentially large in written put or call transactions. The Fund may also use an option spread or option straddle strategy. These strategies may not perform as expected and could expose the Fund to potentially large losses.

Portfolio Turnover Risk. The Fund may actively trade portfolio securities to achieve its investment objective, and active trading may be driven by changes in our quantitative investment models. A high rate of portfolio turnover involves correspondingly high transaction costs, which may adversely affect the Fund’s performance over time and may generate more taxable short-term gains for shareholders.

Preferred Stock Risk. Like other equity securities, preferred stock is subject to the risk that its value may decrease based on actual or perceived changes in the business or financial condition of the issuer. In addition, the value of preferred stocks will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of preferred stock. Preferred stocks are also subject to credit risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payments.

Value Style Risk. Investing in or having exposure to “value” stocks presents the risk that the stocks may never reach what the Adviser believes are their full market values, either because the market fails to recognize what the Adviser considers to be the companies’ true business values or because the Adviser misjudged those values. In addition, there may be periods during which the investment performance of the Fund while using a value strategy may suffer.

Although your actual costs may be higher or lower, based on these assumptions, your cost of investing in the Fund would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by taking long and short positions in the global securities markets. The Fund primarily invests long in common and preferred stocks and in investment companies (“underlying funds”), which include domestic and foreign mutual funds, which may include emerging markets, as well as in exchange traded funds (“ETFs”), closed-end funds, and unit investment trusts. Short positions involve selling a security the Fund does not own in anticipation that the security’s price will decline. The Fund’s typical long equity investment exposure will range from 0% to 150% of net assets, while the Fund’s typical short equity investment exposure will range from 0% to 50% of net assets. The Fund may use leverage (e.g., by borrowing or through derivatives). As a result, the sum of the Fund’s investment exposures may at times exceed the amount of assets invested in the Fund, although these exposures may vary over time.

The Fund may also establish long or short positions in index funds and index-based investments. The Fund may invest directly in derivatives, such as options and futures contracts, or in underlying funds investing in futures contracts and options on futures contracts. These investments may be used, for example, in an effort to earn extra income, to provide adequate liquidity, to adjust exposure to individual securities or markets, to protect all or a portion of the Fund’s portfolio from a decline in value, or to maintain a fully invested position in equity securities.

The Fund’s use of leverage and short positions will vary over time based on the Adviser’s assessment of market conditions, prevailing interest rates and other factors. When selecting investments for the Fund, the Adviser continually evaluates style, market capitalization, sector rotation, and international positions by utilizing a series of quantitative models to perform fundamental and technical analysis in order to identify opportunities that have the best attributes for outperformance. Individual equity selection is driven by the Adviser’s quantitative model that evaluates securities based on exposure to value, quality, momentum, and sentiment characteristics.

	●	Value is a measure of the relative value of a company using metrics such as revenue, cash flow, and income;
	●	Quality is a measure of the financial performance of a company, typically measured by the stability of its earnings and cash flows, along with the strength of its balance sheet;
	●	Momentum is a measure of the rate of change in the price of securities over time; and
	●	Sentiment is a measure of the prevailing attitudes of investors related to anticipated price movements in the market.

There are no investment limitations on market capitalization range or geographic region. The Adviser selects securities that the Adviser believes represent above average market potential relative to market risk. The Fund may focus on stocks or underlying funds investing in stocks that are newer and/or smaller capitalization companies.

The Fund utilizes several defensive tactics to reduce or eliminate its position in common stocks and underlying equity funds in order to attempt to reduce the risk of loss when the Adviser’s quantitative models and evaluation indicate that the risks of the stock market may be greater than the potential rewards. Utilizing its unconstrained tactical strategy, the Fund may invest up to 100% of its net assets in fixed income securities of any maturity and of any credit rating (including unrated and high yield fixed income securities, commonly known as “junk bonds”) and cash equivalent securities. The Fund may invest in underlying fixed income funds that invest in domestic and foreign fixed income securities, ETFs, closed-end funds, and unit investment trusts. The Fund may also buy or sell derivatives, including domestic or international stock index futures or options and option spreads on index future contracts. An option spread is a strategy where the Fund buys two different options on an index, but with different prices or expirations, in order to hedge against declines in equity market value. The use of these techniques may not protect against market declines and may limit the Fund’s participation in market gains, particularly in volatile market conditions.

Other than as set forth in the SAI, the investment policies and limitations of the Fund are not fundamental and may be changed by the Board of Trustees of the Meeder Funds without shareholder approval.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

All investments carry a certain amount of risk and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Loss of money is a risk of investing in a mutual fund. All of the risks listed below are significant to the Fund, regardless of the order in which they appear.

Common Stock Risk. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

Credit Risk. All debt securities are subject to the risk that the issuer or guarantor of the debt security may not make principal or interest payments as they become due, or default entirely on its obligations. The value and liquidity of an issuer’s debt securities will typically decline if the market perceives a deterioration in the creditworthiness of that issuer. In addition, insured debt securities have the credit risk of the insurer in addition to the underlying credit risk of the debt security being insured.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Fixed Income Risk. The Fund is subject to the general risks and considerations associated with investing in debt securities, including the risk that an issuer will fail to make timely payments of principal or interest, or default on its obligations. Lower-rated securities in which the Fund may invest may be more volatile and may decline more in price in response to negative issuer developments or macroeconomic news than higher rated securities. In addition, as interest rates rise, the Fund’s fixed income investments will typically lose value.

Foreign Investment Risk. Investments in foreign issuers, whether directly or indirectly, involve additional risks different from those associated with investments in U.S. issuers. There may be limited information available to investors, and foreign issuers may not be subject to uniform accounting, auditing and financial standards like those applicable to U.S. issuers. Different accounting, corporate governance, regulatory, and market systems may cause foreign investments to be more volatile. Additionally, currency fluctuations my affect the value of foreign investments.

●

Emerging Markets Risk. Investing in emerging markets involves magnifies the risks inherent in foreign investments. These risks include exposure to economic structures that are generally less diverse and mature than found in developed markets, limited availability of reliable information material to an investment decision, exposure to political systems that may be less stability than those of developed countries, and greater exposure to foreign currency fluctuations. The market for the securities of issuers in emerging market typically is small, and a low or nonexistent trading volume in those securities may result in a lack of liquidity and price volatility.

High Yield Risk. The Fund may purchase fixed income securities rated below the investment grade category (non-investment grade bond, speculative grade, or junk bond). Securities in this rating category are considered speculative. Changes in economic conditions or other circumstances may have a greater effect on the ability of issuers of these securities to make principal and interest payments than they do on issuers of investment grade securities. Therefore, fixed income securities in this category may have greater price fluctuations and have a higher risk of default than investment grade securities.

Interest Rate Risk. Fixed income securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund’s fixed income investments will generally decline. On the other hand, if rates fall, the value of the fixed income investments generally increases. Your investment will decline in value if the value of the Fund’s investments decreases. The market value of debt securities (including U.S. government securities) with longer maturities is likely to respond to changes in interest rates to a greater degree than the market value of fixed income securities with shorter maturities.

Investment Company Risk. Because the Fund may invest in underlying mutual funds and unit investment trusts, the value of your investment also will fluctuate in response to the performance of the underlying funds. In addition, you will indirectly bear fees and expenses charged by the underlying investment companies in which the Fund invests in addition to the Fund’s direct fees and expenses. You also may receive taxable capital gains distributions to a greater extent than would be the case if you invested directly in the underlying funds.

●

Closed-end Fund Risk. Closed-end funds involve investment risks different from those associated with other investment companies. Shares of closed-end funds frequently trade at either a premium or discount relative to the value of the securities held by the closed-end fund. Closed-end funds may trade infrequently and with small volume, which may make it hard for the Fund to buy and sell shares. Many closed-end funds also utilize leverage, which can expose the Fund to greater risk of significant changes in the closed-end funds’ share prices and will require payment of interest or dividend expenses, reducing the closed-end fund’s overall return.

●

Exchange Traded Fund and Index Fund Risk. ETFs and index funds will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. In addition, the ETFs and index funds will incur expenses not incurred by their applicable indices. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ability of the ETFs and index funds to track their applicable indices. The Fund also will incur brokerage costs when it purchases ETFs. An ETF may trade at a discount to its net asset value.

Issuer Cybersecurity Risk. Issuers of securities in which the Fund invests, counterparties with which Fund engages in transactions, exchange and other financial market operators, banks, brokers, dealers and other financial institutions may experience cybersecurity breaches. Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; ransomware; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. These breaches may result in harmful disruptions to their operations and may negatively impact the financial condition for the municipal issuer, counterparty or other market participant. The Fund and its shareholders could be negatively impacted as a result.

Leverage Risk. The use of leverage by the Fund, such as borrowing money to purchase securities or the use of derivatives, will cause the Fund to incur additional expenses and magnify the Fund’s gains or losses.

Liquidity Risk. Reduced liquidity affecting an individual security, or an entire market may have an adverse impact on market price and the Fund’s ability to sell particular securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets. The current novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, has had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

Market Capitalization Risk. Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the Fund’s performance could be impacted.

●

Large-Capitalization Risk. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

●

Mid-Capitalization Risk. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

●

Small-Capitalization Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the Adviser relies on quantitative models and information and data supplied by third parties (“Models and Data”). These Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investment risks. When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Many of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the quantitative models used by the Adviser will not be successful in selecting companies for investment or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.

Momentum Style Risk. Investing in or having exposure to securities with positive momentum entails investing in securities that have had positive recent relative performance. These securities may be more volatile than a broad cross-section of securities. In addition, there may be periods during which the investment performance of the Fund while using a momentum strategy may suffer.

Options Strategy Risk. The Fund may buy and sell options as a defensive tactic, to earn income, or to adjust exposure to the markets. As the buyer of a call or put option, the Fund may lose the entire premium paid for the option if the value of the security underlying the option does not rise above the call strike price, or fall below the put strike price, which means the option will expire worthless. As a seller (writer) of a call or put option, the Fund will tend to lose money if the value of the underlying security rises above the call strike price or falls below the put strike price. The Fund’s losses are potentially large in written put or call transactions. The Fund may also use an option spread or option straddle strategy. These strategies may not perform as expected and could expose the Fund to potentially large losses.

Portfolio Turnover Risk. The Fund may actively trade portfolio securities to achieve its investment objective, and active trading may be driven by changes in our various quantitative investment models discussed above. A high rate of portfolio turnover involves correspondingly high transaction costs, which may adversely affect the Fund’s performance over time and may generate more taxable short-term gains for shareholders.

Preferred Stock Risk. Like other equity securities, preferred stock is subject to the risk that its value may decrease based on actual or perceived changes in the business or financial condition of the issuer. In addition, the value of preferred stocks will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of preferred stock. Preferred stocks are also subject to credit risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payments.

Short Sale Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to close out the short position. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of a security.

Value Style Risk. Investing in or having exposure to “value” stocks presents the risk that the stocks may never reach what the Adviser believes are their full market values, either because the market fails to recognize what the Adviser considers to be the companies’ true business values or because the Adviser misjudged those values. In addition, there may be periods during which the investment performance of the Fund while using a value strategy may suffer.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 205% of the average value of its portfolio.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your cost of investing in the Fund would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in common and preferred stocks, as well as fixed income securities. The Fund may also invest in investment companies (“underlying funds”), which include domestic and foreign mutual funds, as well as in exchange traded funds (“ETFs”), closed-end funds and unit investment trusts. The Fund may invest in index funds and index-based investments.

The Fund may also invest directly in derivatives, such as options and futures contracts, or in underlying funds investing in futures contracts and options on futures contracts. These investments may be used, for example, in an effort to earn extra income, to provide adequate liquidity, to adjust exposure to individual securities or markets, to protect all or a portion of the Fund’s portfolio from a decline in value, or to maintain a fully-invested position in equity securities.

Under normal circumstances, the Fund will have a minimum of 30% and a maximum of 70% of its net assets invested in equity securities or underlying funds investing in equity securities. For the equity portion of the portfolio, the Fund may select growth- or value-oriented investments (including specific sectors), without limitation to market capitalization range or geographic region including investments in emerging markets. The Fund will also have a minimum of 30% and a maximum of 70% of its net assets invested in fixed income securities. For the fixed income portion of the portfolio, the Fund may invest in securities of governments throughout the world (including the United States and emerging markets), their agencies and instrumentalities, cash equivalents, income-producing securities including domestic and foreign investment grade and below investment grade bonds, structured instruments (debt securities issued by agencies of the U.S. Government (such as Ginnie Mae, Fannie Mae, and Freddie Mac), corporations and other business entities whose interest and/or principal payments are indexed to certain specific foreign currency exchange rates, interest rates, or one or more other reference indices or obligations), asset-backed securities, inflation-linked securities, commercial paper, certificates of deposit, banker’s acceptances and other bank obligations, money market funds, repurchase agreements, and derivatives, such as futures contracts, options, and swaps. The Fund may invest in fixed income securities of any maturity, and of any credit rating (including unrated securities). In addition, for the fixed income portion of the portfolio, the Fund may invest without limit in higher risk, below-investment grade debt securities, commonly referred to as “high yield securities” or “junk bonds.” The Fund may also invest in fixed income investment companies that invest in domestic and foreign fixed income securities, ETFs, closed-end funds, and unit investments trusts.

Within the equity portion of the strategy, the Adviser continually evaluates style, market capitalization, sector rotation, and international positions, by utilizing a series of quantitative models to perform fundamental and technical analysis, in order to identify opportunities that have the best attributes for outperformance. Individual equity selection is driven by the Adviser’s quantitative model that evaluates securities based on exposure to value, quality, momentum, and sentiment characteristics.

	●	Value is a measure of the relative value of a company using metrics such as revenue, cash flow, and income;
	●	Quality is a measure of the financial performance of a company, typically measured by the stability of its earnings and cash flows, along with the strength of its balance sheet;
	●	Momentum is a measure of the rate of change in the price of securities over time; and
	●	Sentiment is a measure of the prevailing attitudes of investors related to anticipated price movements in the market.

Within the fixed income portion of the strategy, the Adviser uses a combination of quantitative models that seek to measure the relative risks and opportunities of each fixed income market segment based upon economic, market, currency and technical data, and the Adviser’s own assessment of economic and market conditions, to create an optimal allocation of the Fund’s assets among various segments of the fixed income market. After sector allocations are made, the Adviser uses a combination of traditional due diligence, and performance analysis to identify investments for the Fund’s portfolio.

The Fund utilizes several defensive tactics to reduce or eliminate its position in common stocks and underlying equity funds in order to attempt to reduce the risk of loss when the Adviser’s quantitative models and evaluation indicate that the risks of the stock market may be greater than the potential rewards. Consistent with its Principal Investment Strategies, the Fund may shift equity holdings to fixed income securities of any maturity and of any credit rating (including unrated and high yield fixed income securities.

The Fund may invest in underlying fixed income funds that invest in domestic and foreign fixed income securities, ETFs, closed-end funds, and unit investment trusts. The Fund may also buy or sell derivatives, including domestic or international stock index futures or options and option spreads on index future contracts. An option spread is a strategy where the Fund buys two different options on an index, but with different prices or expirations, in order to hedge against declines in equity market value. The use of these techniques may not protect against market declines and may limit the Fund’s participation in market gains, particularly in volatile market conditions.

The Fund addresses asset allocation decisions by adjusting the mix of stocks, bonds and cash in the Fund, within the parameters described above. When the Adviser’s quantitative models and evaluation indicate that the risks of the stock market may be greater than the potential rewards, the Fund will reduce its position in underlying equity securities and underlying equity funds in order to attempt to minimize the risk of loss of capital. The Fund may also reduce its equity exposure by selling short stock index futures contracts. The Fund’s goal is to minimize losses during high-risk market environments and to provide attractive returns during low-risk markets.

Other than as set forth in the SAI, the investment policies and limitations of the Fund are not fundamental and may be changed by the Board of Trustees of the Meeder Funds without shareholder approval.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

All investments carry a certain amount of risk, and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Loss of money is a risk of investing in a mutual fund. All of the risks listed below are significant to the Fund, regardless of the order in which they appear.

Asset-backed Securities Risk. These types of securities are subject to the risks affecting fixed income securities generally and may be particularly volatile. In addition, the value of these securities will be influenced by factors affecting markets from which the collateral is drawn. Some of these securities may receive little or no collateral protection from the underlying assets. The impairment of the value of assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of other collateral or underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund. In addition, the structure of some of these securities is complex and there may be less available information than for other types of securities.

Common Stock Risk. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

Credit Risk. All debt securities are subject to the risk that the issuer or guarantor of the debt security may not make principal or interest payments as they become due, or default entirely on its obligations. The value and liquidity of an issuer’s debt securities will typically decline if the market perceives a deterioration in the creditworthiness of that issuer. In addition, insured debt securities have the credit risk of the insurer in addition to the underlying credit risk of the debt security being insured.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Fixed Income Risk. The Fund is subject to the general risks and considerations associated with investing in debt securities, including the risk that an issuer will fail to make timely payments of principal or interest, or default on its obligations. Lower-rated securities in which the Fund may invest may be more volatile and may decline more in price in response to negative issuer developments or macroeconomic news than higher rated securities. In addition, as interest rates rise, the Fund’s fixed income investments will typically lose value.

Foreign Investment Risk. Investments in foreign issuers, whether directly or indirectly, involve additional risks different from those associated with investments in U.S. issuers. There may be limited information available to investors, and foreign issuers may not be subject to uniform accounting, auditing and financial standards like those applicable to U.S. issuers. Different accounting, corporate governance, regulatory, and market systems may cause foreign investments to be more volatile. Additionally, currency fluctuations my affect the value of foreign investments.

●

Emerging Markets Risk. Investing in emerging markets involves magnifies the risks inherent in foreign investments. These risks include exposure to economic structures that are generally less diverse and mature than found in developed markets, limited availability of reliable information material to an investment decision, exposure to political systems that may be less stability than those of developed countries, and greater exposure to foreign currency fluctuations. The market for the securities of issuers in emerging market typically is small, and a low or nonexistent trading volume in those securities may result in a lack of liquidity and price volatility.

Government Securities Risk. The Fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities. These securities may be backed by the credit of the government as a whole or only by the issuing agency. No assurance can be given that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law. Neither the U.S. government nor its agencies guarantee the market value of their securities, and interest rate changes, prepayments and other factors may affect the value of government securities.

High Yield Risk. The Fund may purchase fixed income securities rated below the investment grade category (non-investment grade bond, speculative grade, or junk bond). Securities in this rating category are considered speculative. Changes in economic conditions or other circumstances may have a greater effect on the ability of issuers of these securities to make principal and interest payments than they do on issuers of investment grade securities. Therefore, fixed income securities in this category may have greater price fluctuations and have a higher risk of default than investment grade securities.

Interest Rate Risk. Fixed income securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund’s fixed income investments will generally decline. On the other hand, if rates fall, the value of the fixed income investments generally increases. Your investment will decline in value if the value of the Fund’s investments decreases. The market value of debt securities (including U.S. Government securities) with longer maturities is likely to respond to changes in interest rates to a greater degree than the market value of fixed income securities with shorter maturities.

Investment Company Risk. Because the Fund may invest in underlying mutual funds and unit investment trusts, the value of your investment also will fluctuate in response to the performance of the underlying funds. In addition, you will indirectly bear fees and expenses charged by the underlying investment companies in which the Fund invests in addition to the Fund’s direct fees and expenses. You also may receive taxable capital gains distributions to a greater extent than would be the case if you invested directly in the underlying funds.

	●	Closed-end Fund Risk. Closed-end funds involve investment risks different from those associated with other investment companies. Shares of closed-end funds frequently trade at either a premium or discount relative to the value of the securities held by the closed-end fund. Closed-end funds may trade infrequently and with small volume, which may make it hard for the Fund to buy and sell shares. Many closed-end funds also utilize leverage, which can expose the Fund to greater risk of significant changes in the closed-end funds’ share prices and will require payment of interest or dividend expenses, reducing the closed-end fund’s overall return.

●

Exchange Traded Fund and Index Fund Risk. ETFs and index funds will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. In addition, the ETFs and index funds will incur expenses not incurred by their applicable indices. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ability of the ETFs and index funds to track their applicable indices. The Fund also will incur brokerage costs when it purchases ETFs. An ETF may trade at a discount to its net asset value.

Issuer Cybersecurity Risk. Issuers of securities in which the Fund invests, counterparties with which Fund engages in transactions, exchange and other financial market operators, banks, brokers, dealers and other financial institutions may experience cybersecurity breaches. Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; ransomware; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. These breaches may result in harmful disruptions to their operations and may negatively impact the financial condition for the municipal issuer, counterparty or other market participant. The Fund and its shareholders could be negatively impacted as a result.

Liquidity Risk. Reduced liquidity affecting an individual security or an entire market may have an adverse impact on market price and the Fund’s ability to sell particular securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets. The current novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, has had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

Market Capitalization Risk. Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the Fund’s performance could be impacted.

●

Large-Capitalization Risk. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

●

Mid-Capitalization Risk. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

●

Small-Capitalization Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the Adviser relies on quantitative models and information and data supplied by third parties (“Models and Data”). These Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investment risks. When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Many of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the quantitative models used by the Adviser will not be successful in selecting companies for investment or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.

Momentum Style Risk. Investing in or having exposure to securities with positive momentum entails investing in securities that have had positive recent relative performance. These securities may be more volatile than a broad cross-section of securities. In addition, there may be periods during which the investment performance of the Fund while using a momentum strategy may suffer.

Options Strategy Risk. The Fund may buy and sell options as a defensive tactic, to earn income, or to adjust exposure to the markets. As the buyer of a call or put option, the Fund may lose the entire premium paid for the option if the value of the security underlying the option does not rise above the call strike price, or fall below the put strike price, which means the option will expire worthless. As a seller (writer) of a call or put option, the Fund will tend to lose money if the value of the underlying security rises above the call strike price or falls below the put strike price. The Fund’s losses are potentially large in written put or call transactions. The Fund may also use an option spread or option straddle strategy. These strategies may not perform as expected and could expose the Fund to potentially large losses.

Portfolio Turnover Risk. The Fund may actively trade portfolio securities to achieve its investment objective, and active trading may be driven by changes in our quantitative investment models. A high rate of portfolio turnover involves correspondingly high transaction costs, which may adversely affect the Fund’s performance over time and may generate more taxable short-term gains for shareholders.

Preferred Stock Risk. Like other equity securities, preferred stock is subject to the risk that its value may decrease based on actual or perceived changes in the business or financial condition of the issuer. In addition, the value of preferred stocks will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of preferred stock. Preferred stocks are also subject to credit risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payments.

Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.

Short Sale Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to close out the short position. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of a security.

Sovereign Debt Risk. Sovereign debt securities are issued or guaranteed by foreign governmental entities. These investments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt. There is no legal process for collecting sovereign debts that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected.

Value Style Risk. Investing in or having exposure to “value” stocks presents the risk that the stocks may never reach what the Adviser believes are their full market values, either because the market fails to recognize what the Adviser considers to be the companies’ true business values or because the Adviser misjudged those values. In addition, there may be periods during which the investment performance of the Fund while using a value strategy may suffer.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 210% of the average value of its portfolio.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your cost of investing in the Fund would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in common and preferred stocks, as well as fixed income securities. The Fund may also invest in investment companies (“underlying funds”), which include domestic and foreign mutual funds, as well as in exchange traded funds (“ETFs”), closed-end funds, and unit investment trusts. In addition, the Fund may invest in index funds and index-based investments, such as Standard & Poor’s Depositary Receipts (SPDRs), and may invest directly in, or in underlying funds investing in, futures contracts and options on futures contracts.

Under normal circumstances, the Fund will have a minimum of 0% and a maximum of 30% of its net assets invested in equity securities or underlying funds investing in equity securities. For the equity portion of the portfolio, the Fund may select growth- or value-oriented investments (including specific sectors), without limitation to market capitalization range or geographic region, including emerging markets.

The Fund will also have a minimum of 70% and a maximum of 100% of its net assets invested in fixed income securities. For the fixed income portion of the portfolio, the Fund may invest in securities of governments throughout the world (including the United States and emerging markets), their agencies and instrumentalities, cash and cash equivalents, income-producing securities including domestic and foreign investment grade and non-investment grade bonds, structured instruments (debt securities issued by agencies of the United States Government (such as Ginnie Mae, Fannie Mae, and Freddie Mac), corporations and other business entities whose interest and/or principal payments are indexed to certain specific foreign currency exchange rates, interest rates, or one or more other reference indices or obligations), asset-backed securities, inflation-linked securities, commercial paper, certificates of deposit, banker’s acceptances and other bank obligations, money market funds, repurchase agreements, and derivatives, such as futures contracts, options, and swaps. The Fund may invest in fixed income securities of any maturity, and of any credit rating (including unrated securities). In addition, for the fixed income portion of the portfolio, the Fund may invest without limit in higher risk, below-investment grade debt securities, commonly referred to as “high yield securities” or “junk bonds.” The Fund may also invest in fixed income investment companies that invest in domestic and foreign fixed income securities, ETFs, closed-end funds, and unit investments trusts. With respect to both the equity and fixed income portions of the portfolios, the Fund does not concentrate in any particular industry or sector.

Additionally, the Fund may invest directly in derivatives, such as options and futures contracts, or in underlying funds investing in futures contracts and options on futures contracts.

These investments may be used, for example, in an effort to earn extra income, to provide adequate liquidity, to adjust exposure to individual securities or markets, to protect all or a portion of the Fund’s portfolio from a decline in value, or to maintain a fully-invested position in equity securities.

Within the equity portion of the strategy, the Adviser continually evaluates style, market capitalization, sector rotation, and international positions by utilizing a series of quantitative models to perform fundamental and technical analysis in order to identify opportunities that have the best attributes for outperformance. Individual equity selection is driven by the Adviser’s quantitative model that evaluates securities based on exposure to value, quality, momentum, and sentiment characteristics.

	●	Value is a measure of the relative value of a company using metrics such as revenue, cash flow, and income;
	●	Quality is a measure of the financial performance of a company, typically measured by the stability of its earnings and cash flows, along with the strength of its balance sheet;
	●	Momentum is a measure of the rate of change in the price of securities over time; and
	●	Sentiment is a measure of the prevailing attitudes of investors related to anticipated price movements in the market.

Within the fixed income portion of the strategy, the Adviser uses a combination of quantitative models that seek to measure the relative risks and opportunities of each fixed income market segment based upon economic, market, currency and technical data and the Adviser’s own assessment of economic and market conditions to create an optimal allocation of the Fund’s assets among various segments of the fixed income market. After sector allocations are made, the Adviser uses a combination of traditional due diligence, and performance analysis to identify investments for the Fund’s portfolio.

The Fund utilizes several defensive tactics to reduce or eliminate its position in common stocks and underlying equity funds in order to attempt to reduce the risk of loss when the Adviser’s quantitative models and evaluation indicate that the risks of the stock market may be greater than the potential rewards. The Fund may shift equity holdings to fixed income securities of any maturity and of any credit rating (including unrated and high yield fixed income securities) and cash equivalent securities. The Fund may invest in underlying fixed income funds that invest in domestic and foreign fixed income securities, ETFs, closed-end funds, and unit investment trusts. The Fund may also buy or sell derivatives, including domestic or international stock index futures or options and option spreads on index future contracts. An option spread is a strategy where the Fund buys two different options on an index, but with different prices or expirations, in order to hedge against declines in equity market value. The use of these techniques may not protect against market declines and may limit the Fund’s participation in market gains, particularly in volatile market conditions.

Other than as set forth in the SAI, the investment policies and limitations of the Fund are not fundamental and may be changed by the Board of Trustees of the Meeder Funds without shareholder approval.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

All investments carry a certain amount of risk, and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Loss of money is a risk of investing in a mutual fund. All of the risks listed below are significant to the Fund, regardless of the order in which they appear.

Asset-backed Securities Risk. These types of securities are subject to the risks affecting fixed income securities generally and may be particularly volatile. In addition, the value of these securities will be influenced by factors affecting markets from which the collateral is drawn. Some of these securities may receive little or no collateral protection from the underlying assets. The impairment of the value of assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of other collateral or underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund. In addition, the structure of some of these securities is complex and there may be less available information than for other types of securities.

Common Stock Risk. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

Credit Risk. All debt securities are subject to the risk that the issuer or guarantor of the debt security may not make principal or interest payments as they become due, or default entirely on its obligations. The value and liquidity of an issuer’s debt securities will typically decline if the market perceives a deterioration in the creditworthiness of that issuer. In addition, insured debt securities have the credit risk of the insurer in addition to the underlying credit risk of the debt security being insured.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Fixed Income Risk. The Fund is subject to the general risks and considerations associated with investing in debt securities, including the risk that an issuer will fail to make timely payments of principal or interest, or default on its obligations. Lower-rated securities in which the Fund may invest may be more volatile and may decline more in price in response to negative issuer developments or macroeconomic news than higher rated securities. In addition, as interest rates rise, the Fund’s fixed income investments will typically lose value.

Foreign Investment Risk. Investments in foreign issuers, whether directly or indirectly, involve additional risks different from those associated with investments in U.S. issuers. There may be limited information available to investors, and foreign issuers may not be subject to uniform accounting, auditing and financial standards like those applicable to U.S. issuers. Different accounting, corporate governance, regulatory, and market systems may cause foreign investments to be more volatile. Additionally, currency fluctuations my affect the value of foreign investments.

●

Emerging Markets Risk. Investing in emerging markets involves magnifies the risks inherent in foreign investments. These risks include exposure to economic structures that are generally less diverse and mature than found in developed markets, limited availability of reliable information material to an investment decision, exposure to political systems that may be less stability than those of developed countries, and greater exposure to foreign currency fluctuations. The market for the securities of issuers in emerging market typically is small, and a low or nonexistent trading volume in those securities may result in a lack of liquidity and price volatility.

Government Securities Risk. The Fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities. These securities may be backed by the credit of the government as a whole or only by the issuing agency. No assurance can be given that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law. Neither the U.S. government nor its agencies guarantee the market value of their securities, and interest rate changes, prepayments and other factors may affect the value of government securities.

High Yield Risk. The Fund may purchase fixed income securities rated below the investment grade category (non-investment grade bond, speculative grade, or junk bond) without limitation. Securities in this rating category are considered speculative. Changes in economic conditions or other circumstances may have a greater effect on the ability of issuers of these securities to make principal and interest payments than they do on issuers of investment grade securities. Therefore, fixed income securities in this category may have greater price fluctuations and have a higher risk of default than investment grade securities.

Interest Rate Risk. Fixed income securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund’s fixed income investments will generally decline. On the other hand, if rates fall, the value of the fixed income investments generally increases. Your investment will decline in value if the value of the Fund’s investments decreases. The market value of debt securities (including U.S. Government securities) with longer maturities is likely to respond to changes in interest rates to a greater degree than the market value of fixed income securities with shorter maturities.

Investment Company Risk. Because the Fund may invest in underlying mutual funds and unit investment trusts, the value of your investment also will fluctuate in response to the performance of the underlying funds. In addition, you will indirectly bear fees and expenses charged by the underlying investment companies in which the Fund invests in addition to the Fund’s direct fees and expenses. You also may receive taxable capital gains distributions to a greater extent than would be the case if you invested directly in the underlying funds.

	●	Closed-end Fund Risk. Closed-end funds involve investment risks different from those associated with other investment companies. Shares of closed-end funds frequently trade at either a premium or discount relative to the value of the securities held by the closed-end fund. Closed-end funds may trade infrequently and with small volume, which may make it hard for the Fund to buy and sell shares. Many closed-end funds also utilize leverage, which can expose the Fund to greater risk of significant changes in the closed-end funds’ share prices and will require payment of interest or dividend expenses, reducing the closed-end fund’s overall return.

●

Exchange Traded Fund and Index Fund Risk. ETFs and index funds will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. In addition, the ETFs and index funds will incur expenses not incurred by their applicable indices. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ability of the ETFs and index funds to track their applicable indices. The Fund also will incur brokerage costs when it purchases ETFs. An ETF may trade at a discount to its net asset value.

Issuer Cybersecurity Risk. Issuers of securities in which the Fund invests, counterparties with which Fund engages in transactions, exchange and other financial market operators, banks, brokers, dealers and other financial institutions may experience cybersecurity breaches. Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; ransomware; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. These breaches may result in harmful disruptions to their operations and may negatively impact the financial condition for the municipal issuer, counterparty or other market participant. The Fund and its shareholders could be negatively impacted as a result.

Liquidity Risk. Reduced liquidity affecting an individual security, or an entire market may have an adverse impact on market price and the Fund’s ability to sell particular securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets. The current novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, has had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

Market Capitalization Risk. Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the Fund’s performance could be impacted.

●

Large-Capitalization Risk. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

●

Mid-Capitalization Risk. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

●

Small-Capitalization Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the Adviser relies on quantitative models and information and data supplied by third parties (“Models and Data”). These Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investment risks. When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Many of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the quantitative models used by the Adviser will not be successful in selecting companies for investment or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.

Momentum Style Risk. Investing in or having exposure to securities with positive momentum entails investing in securities that have had positive recent relative performance. These securities may be more volatile than a broad cross-section of securities. In addition, there may be periods during which the investment performance of the Fund while using a momentum strategy may suffer.

Options Strategy Risk. The Fund may buy and sell options as a defensive tactic, to earn income, or to adjust exposure to the markets. As the buyer of a call or put option, the Fund may lose the entire premium paid for the option if the value of the security underlying the option does not rise above the call strike price, or fall below the put strike price, which means the option will expire worthless. As a seller (writer) of a call or put option, the Fund will tend to lose money if the value of the underlying security rises above the call strike price or falls below the put strike price. The Fund’s losses are potentially large in written put or call transactions. The Fund may also use an option spread or option straddle strategy. These strategies may not perform as expected and could expose the Fund to potentially large losses.

Portfolio Turnover Risk. The Fund may actively trade portfolio securities to achieve its investment objective, and active trading may be driven by changes in our quantitative investment models. A high rate of portfolio turnover involves correspondingly high transaction costs, which may adversely affect the Fund’s performance over time and may generate more taxable short-term gains for shareholders.

Preferred Stock Risk. Like other equity securities, preferred stock is subject to the risk that its value may decrease based on actual or perceived changes in the business or financial condition of the issuer. In addition, the value of preferred stocks will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of preferred stock. Preferred stocks are also subject to credit risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payments.

Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.

Sovereign Debt Risk. Sovereign debt securities are issued or guaranteed by foreign governmental entities. These investments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt. There is no legal process for collecting sovereign debts that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected.

Value Style Risk. Investing in or having exposure to “value” stocks presents the risk that the stocks may never reach what the Adviser believes are their full market values, either because the market fails to recognize what the Adviser considers to be the companies’ true business values or because the Adviser misjudged those values. In addition, there may be periods during which the investment performance of the Fund while using a value strategy may suffer.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 64% of the average value of its portfolio.

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your cost of investing in the Fund would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal conditions, at least 60% of the Fund’s net assets will be invested in common stock, rights and warrants of mid-capitalization companies. Mid-capitalization companies are defined as those whose market capitalizations are similar to the market capitalization of companies in the S&P Midcap 400 Index, a widely used benchmark for mid-sized U.S. company stock performance. The market capitalization range of the S&P Midcap 400 as of December 31, 2021was approximately 1.7billion to 33.7 billion. Typically, the Fund will be diversified throughout all major industry sectors. However, more emphasis is given to capitalization levels and there are occasions when all sectors are not represented in the Fund’s portfolio.

For the portion of the portfolio allocated to mid-capitalization companies, the Fund employs a quantitative investment approach that utilizes an investment model to determine which securities are to be added or removed from the Fund’s portfolio on an annual basis. Stocks in the portfolio whose value has risen above or fallen below the predetermined market capitalization ranges are sold, while new undervalued stocks that have moved into the predetermined capitalization ranges are added to the Fund’s portfolio. The Fund’s holdings are then restructured to create an equally weighted portfolio of equity securities.

Depending on the Adviser’s assessment of market conditions, the Fund may allocate up to 40% of its net assets to equity securities of large-capitalization or small-capitalization companies. The Fund pursues this objective by primarily investing in derivatives, mutual funds or exchange traded funds (“ETFs”) that provide exposure to the desired market sector. When selecting these investments, the Adviser continually evaluates style and, market capitalization factors utilizing a series of quantitative models to perform fundamental and technical analysis in order to identify opportunities that have the best attributes for outperformance.

The Fund may invest directly in derivatives, such as options and futures contracts, or in underlying funds investing in futures contracts and options on futures contracts. These investments may be used to earn extra income, to provide adequate liquidity, to adjust exposure to individual securities or markets, to protect all or a portion of the Fund’s portfolio from a decline in value, or to maintain a fully invested position in equity securities. The Fund also may invest in index funds, index-based investments, open-end investment companies, and exchange traded funds.

Other than as set forth in the SAI, the investment policies and limitations of the Fund are not fundamental and may be changed by the Board of Trustees of the Meeder Funds without shareholder approval.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

All investments carry a certain amount of risk, and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Loss of money is a risk of investing in a mutual fund. All of the risks listed below are significant to the Fund, regardless of the order in which they appear.

Common Stock Risk. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Investment Company Risk. Because the Fund may invest in underlying mutual funds and unit investment trusts, the value of your investment also will fluctuate in response to the performance of the underlying funds. In addition, you will indirectly bear fees and expenses charged by the underlying investment companies in which the Fund invests in addition to the Fund’s direct fees and expenses. You also may receive taxable capital gains distributions to a greater extent than would be the case if you invested directly in the underlying funds.

●

Exchange Traded Fund and Index Fund Risk. ETFs and index funds will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. In addition, the ETFs and index funds will incur expenses not incurred by their applicable indices. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ability of the ETFs and index funds to track their applicable indices. The Fund also will incur brokerage costs when it purchases ETFs. An ETF may trade at a discount to its net asset value.

Issuer Cybersecurity Risk. Issuers of securities in which the Fund invests, counterparties with which Fund engages in transactions, exchange and other financial market operators, banks, brokers, dealers and other financial institutions may experience cybersecurity breaches. Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; ransomware; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. These breaches may result in harmful disruptions to their operations and may negatively impact the financial condition for the municipal issuer, counterparty or other market participant. The Fund and its shareholders could be negatively impacted as a result.

Liquidity Risk. Reduced liquidity affecting an individual security, or an entire market may have an adverse impact on market price and the Fund’s ability to sell particular securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets. The current novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, has had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

Market Capitalization Risk. Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the Fund’s performance could be impacted.

●

Large-Capitalization Risk. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

●

Mid-Capitalization Risk. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

●

Small-Capitalization Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the Adviser relies on quantitative models and information and data supplied by third parties (“Models and Data”). These Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investment risks. When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Many of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the quantitative models used by the Adviser will not be successful in selecting companies for investment or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.

Options Strategy Risk. The Fund may buy and sell options as a defensive tactic, to earn income, or to adjust exposure to the markets. As the buyer of a call or put option, the Fund may lose the entire premium paid for the option if the value of the security underlying the option does not rise above the call strike price, or fall below the put strike price, which means the option will expire worthless. As a seller (writer) of a call or put option, the Fund will tend to lose money if the value of the underlying security rises above the call strike price or falls below the put strike price. The Fund’s losses are potentially large in written put or call transactions. The Fund may also use an option spread or option straddle strategy. These strategies may not perform as expected and could expose the Fund to potentially large losses.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the current year, the Fund’s portfolio turnover rate was 250% of the average value of its portfolio.

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your cost of investing in the Fund would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, under normal market conditions, invests at least 80% of its net assets in fixed income securities, principally mutual and exchange traded funds that invest in domestic and foreign fixed income securities. Fixed income securities utilized by the Fund include bonds and other instruments issued by the U.S. government, municipal governments, foreign governments, government agencies or instrumentalities, U.S. and foreign corporations, including mortgage and asset-backed securities, inflation protected securities, convertible bonds, structured instruments, commercial paper, certificates of deposit, money market funds and repurchase agreements.

The Fund may invest in fixed income securities of any duration and may utilize derivative investments that provide exposure to fixed income securities. The Adviser utilizes a quantitative model to assist in managing the duration of the Fund’s investment portfolio. Duration is a measure of a debt instrument’s interest-rate sensitivity. The longer a debt instrument’s duration, the more sensitive the instrument is to shifts in interest rates. As a general rule, a 1% rise in interest rates means a 1% fall in value for every year of duration. For example, if rates were to rise 1%, a bond or debt instrument with a 5-year average duration would likely lose approximately 5% of its value. Under normal circumstances, the average portfolio duration of the fixed income securities held by the Fund will not exceed ten years. The Fund may also have a negative duration. Average portfolio duration will change depending on the Adviser’s interest rate expectations and outlook on changing market, economic, and political conditions.

The Fund may invest in fixed income securities of any credit quality, including below-investment grade securities (“high-yield” or “junk bonds”), including distressed debt. The Fund may also invest in non-U.S. denominated securities (“foreign securities”), including securities from issuers in countries whose economies are less developed (“emerging markets”). Foreign securities include securities issued by non-U.S. denominated governments, foreign government agencies, and corporations located in foreign or emerging markets.

The Fund may invest in derivative instruments, such as options, futures contracts, foreign forward currency exchange contracts, interest rate futures or swaps, and credit default swaps. When utilizing derivatives, the Fund may purchase or sell long or short positions or create leverage. Derivative transactions may be used to enhance the Fund’s returns or liquidity, to obtain efficient exposure to certain market segments, and to adjust the duration of the portfolio.

The Fund may purchase shares of fixed income mutual funds, exchange traded funds, closed end funds and unit investment trusts to provide efficient and diversified exposure to domestic, foreign or emerging market segments, including inverse and leveraged ETFs and affiliated money market funds. The Fund may also invest up to 20% of its net assets in equity securities, including preferred stock, convertible securities, common stocks and real estate investment trusts (“REITs”).

The Adviser employs a tactical investment strategy with a flexible asset allocation structure. The Fund can and will adjust its allocation of investments in response to changing trends in various market segments. The Fund will invest in specific fixed income market segments when the quantitative models signal a favorable market trend in combination with the Adviser’s own assessment of economic and market conditions to create an optimal allocation of the Fund’s assets. The Adviser may shift the Fund’s investments between fixed income market segments across the credit quality spectrum, including U.S. government securities, high yield securities, and cash or its equivalents.

Investment selection is primarily driven by proprietary quantitative models that evaluate macroeconomic and segment-specific technical factors to identify market trends and measure the relative risks and opportunities of each fixed income market segment. When selecting fixed income securities for the Fund, the Adviser uses a combination of traditional due diligence, and performance analysis to identify investments for the Fund’s portfolio.

Other than as set forth in the SAI, the investment policies and limitations of the Fund are not fundamental and may be changed by the Board of Trustees of the Meeder Funds without shareholder approval.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

All investments carry a certain amount of risk, and the Fund cannot guarantee that it will achieve its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Loss of money is a risk of investing in a mutual fund. All of the risks listed below are significant to the Fund, regardless of the order in which they appear.

Asset-backed Securities Risk. These types of securities are subject to the risks affecting fixed income securities generally and may be particularly volatile. In addition, the value of these securities will be influenced by factors affecting markets from which the collateral is drawn. Some of these securities may receive little or no collateral protection from the underlying assets. The impairment of the value of assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of other collateral or underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund. In addition, the structure of some of these securities is complex and there may be less available information than for other types of securities.

Convertible Securities Risk. Convertible securities are fixed income securities that the Fund has the option to exchange for equity securities at a specified conversion price. Consequently, the value of the convertible security may be exposed to the stock market risk of the underlying stock or may be exposed to the interest rate or credit risk of the issuer.

Credit Risk. All debt securities are subject to the risk that the issuer or guarantor of the debt security may not make principal or interest payments as they become due, or default entirely on its obligations. The value and liquidity of an issuer’s debt securities will typically decline if the market perceives a deterioration in the creditworthiness of that issuer. In addition, insured debt securities have the credit risk of the insurer in addition to the underlying credit risk of the debt security being insured.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Distressed Debt Risk. Distressed bonds are speculative and involve substantial risks in addition to the risks of investing in high-yield debt securities. The Fund is subject to an increased risk that it may lose a portion or all of its investment in the distressed debt and may incur higher expenses trying to protect its interests in distressed debt. The prices of distressed bonds are likely to be more sensitive to adverse economic changes or individual issuer developments than the prices of higher rated securities.

Fixed Income Risk. The Fund is subject to the general risks and considerations associated with investing in debt securities, including the risk that an issuer will fail to make timely payments of principal or interest, or default on its obligations. Lower-rated securities in which the Fund may invest may be more volatile and may decline more in price in response to negative issuer developments or macroeconomic news than higher rated securities. In addition, as interest rates rise, the Fund’s fixed income investments will typically lose value.

Foreign Investment Risk. Investments in foreign issuers, whether directly or indirectly, involve additional risks different from those associated with investments in U.S. issuers. There may be limited information available to investors, and foreign issuers may not be subject to uniform accounting, auditing and financial standards like those applicable to U.S. issuers. Different accounting, corporate governance, regulatory, and market systems may cause foreign investments to be more volatile. Additionally, currency fluctuations my affect the value of foreign investments.

●

Emerging Markets Risk. Investing in emerging markets involves magnifies the risks inherent in foreign investments. These risks include exposure to economic structures that are generally less diverse and mature than found in developed markets, limited availability of reliable information material to an investment decision, exposure to political systems that may be less stability than those of developed countries, and greater exposure to foreign currency fluctuations. The market for the securities of issuers in emerging market typically is small, and a low or nonexistent trading volume in those securities may result in a lack of liquidity and price volatility.

Government Securities Risk. The Fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities. These securities may be backed by the credit of the government as a whole or only by the issuing agency. No assurance can be given that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law. Neither the U.S. government nor its agencies guarantee the market value of their securities, and interest rate changes, prepayments and other factors may affect the value of government securities.

High Yield Risk. The Fund may purchase fixed income securities rated below the investment grade category (non-investment grade bond, speculative grade, or junk bond). Securities in this rating category are considered speculative. Changes in economic conditions or other circumstances may have a greater effect on the ability of issuers of these securities to make principal and interest payments than they do on issuers of investment grade securities. Therefore, fixed income securities in this category may have greater price fluctuations and have a higher risk of default than investment grade securities.

Interest Rate Risk. Fixed income securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund’s fixed income investments will generally decline. On the other hand, if rates fall, the value of the fixed income investments generally increases. Your investment will decline in value if the value of the Fund’s investments decreases. The market value of debt securities (including U.S. Government securities) with longer maturities is likely to respond to changes in interest rates to a greater degree than the market value of fixed income securities with shorter maturities.

Investment Company Risk. Because the Fund may invest in underlying mutual funds and unit investment trusts, the value of your investment also will fluctuate in response to the performance of the underlying funds. In addition, you will indirectly bear fees and expenses charged by the underlying investment companies in which the Fund invests in addition to the Fund’s direct fees and expenses. You also may receive taxable capital gains distributions to a greater extent than would be the case if you invested directly in the underlying funds.

●

Closed-end Fund Risk. Closed-end funds involve investment risks different from those associated with other investment companies. Shares of closed-end funds frequently trade at either a premium or discount relative to the value of the securities held by the closed-end fund. Closed-end funds may trade infrequently and with small volume, which may make it hard for the Fund to buy and sell shares. Many closed-end funds also utilize leverage, which can expose the Fund to greater risk of significant changes in the closed-end funds’ share prices and will require payment of interest or dividend expenses, reducing the closed-end fund’s overall return.

●

Exchange Traded Fund and Index Fund Risk. ETFs and index funds will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. In addition, the ETFs and index funds will incur expenses not incurred by their applicable indices. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ability of the ETFs and index funds to track their applicable indices. The Fund also will incur brokerage costs when it purchases ETFs. An ETF may trade at a discount to its net asset value.

●

Inverse and Leveraged Fund Risk. The Fund may utilize inverse ETFs that seek to provide the inverse daily return of a particular index or group of securities. Over time, the inverse ETF’s returns may differ dramatically from the returns of the underlying index, an effect exacerbated with longer holding periods. Use of inverse and leveraged ETFs will amplify the Fund’s gains and losses. Most leveraged ETFs “reset” daily. Due to the effect of compounding, their performance over longer periods of time can differ significantly from the performance of their underlying index during the same period of time.

Leverage Risk. The use of leverage by the Fund, such as borrowing money to purchase securities or the use of derivatives, will cause the Fund to incur additional expenses and magnify the Fund’s gains or losses.

Liquidity Risk. Reduced liquidity affecting an individual security, or an entire market may have an adverse impact on market price and the Fund’s ability to sell particular securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets. The current novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, has had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the Adviser relies on quantitative models and information and data supplied by third parties (“Models and Data”). These Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investment risks. When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Many of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the quantitative models used by the Adviser will not be successful in selecting companies for investment or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.

Municipal Securities Risk. The value of municipal bonds that depend on a specific revenue source or general revenue source to fund their payment obligations may fluctuate as a result of changes in the cash flows generated by the revenue source(s) or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source(s). Also downgrades or defaults during economic downturns or similar periods of economic stress, could affect the market values and marketability of municipal obligations. Changes in a municipality’s financial circumstance may make it difficult for the municipality to make interest and principal payments when due.

Options Strategy Risk. The Fund may buy and sell options as a defensive tactic, to earn income, or to adjust exposure to the markets. As the buyer of a call or put option, the Fund may lose the entire premium paid for the option if the value of the security underlying the option does not rise above the call strike price, or fall below the put strike price, which means the option will expire worthless. As a seller (writer) of a call or put option, the Fund will tend to lose money if the value of the underlying security rises above the call strike price or falls below the put strike price. The Fund’s losses are potentially large in written put or call transactions. The Fund may also use an option spread or option straddle strategy. These strategies may not perform as expected and could expose the Fund to potentially large losses.

Portfolio Turnover Risk. The Fund may actively trade portfolio securities to achieve its investment objective, and active trading may be driven by changes in our quantitative investment models. A high rate of portfolio turnover involves correspondingly high transaction costs, which may adversely affect the Fund’s performance over time and may generate more taxable short-term gains for shareholders.

REIT Risk. The value of REITs may be affected by changes in the value and vacancy rate of the underlying property owned by the REITs, while the value of mortgage REITs may be affected by the quality of any credit extended. Investment in REITs involves risks similar to those associated with investing in small capitalization companies, and REITs (especially mortgage REITs) are subject to interest rate risks. Mortgage REITs are also subject to prepayment risk. Because REITs incur expenses like management fees, investments in REITs also add an additional layer of expenses. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law, or (ii) maintain their exemptions from registration under the Investment Company Act of 1940.

Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.

Short Sale Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to close out the short position. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of a security.

Sovereign Debt Risk. Sovereign debt securities are issued or guaranteed by foreign governmental entities. These investments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt. There is no legal process for collecting sovereign debts that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected.
