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 49.06% of the average value of its portfolio.

It assumes a 5% return each year and no change in expenses. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading] rr_StrategyHeading <span style="color:#000000;font-family:Arial;font-size:12pt;font-weight:bold;">Principal Investment Strategies</span>
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund is a “fund-of-funds” that invests primarily in affiliated mutual funds representing a variety of asset classes. The Fund invests in a professionally selected mix of different asset classes that is tailored for investors planning to retire in, or close to, the year 2060. Therefore, the Fund currently emphasizes the pursuit of long-term growth of capital, and invests heavily in equity securities, such as common stocks of U.S. and international companies, including smaller companies. As of January 31, 2025, the Fund allocated approximately 64% of its net assets in U.S. stocks (including smaller company stocks), approximately 26% in international stocks, and approximately 10% in bonds. As the year 2060 approaches, the Fund’s allocations to different asset classes will progressively become more conservative with increasing emphasis on investments that provide for income and preservation of capital, and less on those offering the potential for growth. The Fund invests primarily in affiliated portfolios of Nationwide Mutual Funds, but also may invest in unaffiliated exchange-traded funds (each, an “Underlying Fund” or collectively, “Underlying Funds”), that collectively represent several asset classes. Certain Underlying Funds are actively managed, and other Underlying Funds are “index” funds that invest directly in equity securities, bonds or other securities with a goal of obtaining investment returns that closely track a benchmark stock or bond index. Some Underlying Funds use futures, swaps and options, which are derivatives, either to hedge against investment risks, to obtain exposure to certain securities or groups of securities, to take short positions in certain securities, or otherwise to increase returns. Although the Fund seeks to provide diversification across several asset classes, the Fund invests a significant portion of its assets in a small number of issuers (i.e., Underlying Funds). However, the Fund may invest directly in securities and derivatives (futures, options, and swaps) in addition to investing in Underlying Funds. Further, the Underlying Funds in which the Fund invests generally are diversified. The Fund is designed for aggressive investors who are comfortable with assuming the risks associated with investing in a high percentage of stocks, including international stocks and smaller companies. The Fund seeks exposure to securities of foreign issuers, which may include securities of issuers in emerging market countries. The Fund also assumes that its investors will retire in or close to 2060 at the age of 65, and that such investors want to maximize their long-term returns and have a high tolerance for possible short-term losses. As the Fund reaches the year of its target date, Nationwide Fund Advisors (the “Adviser”) expects to recommend that the Nationwide Mutual Funds' Board of Trustees approve combining the Fund with the Nationwide Destination Retirement Fund, which offers investors the most conservative and income-oriented allocation scheme of the Nationwide Target Destination Funds. If the combination is approved and applicable regulatory requirements are met, the Fund's shareholders would then become shareholders of the Nationwide Destination Retirement Fund. Shareholders will be provided with additional information at that time, including information pertaining to any tax consequences of the combination.

Risk [Text Block] rr_RiskTextBlock The Fund cannot guarantee that it will achieve its investment objective. As with any fund, the value of the Fund’s investments—and therefore, the value of Fund shares—may fluctuate. These changes may occur because of:Loss of money is a risk of investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Loss of money is a risk of investing in the Fund.
Nationwide Destination 2060 Fund | Fund of Funds Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Fund-of-funds risk – there are certain risks associated with a structure whereby the Fund invests primarily in other mutual funds. These risks include that: (1) the Fund will indirectly pay a proportional share of the fees and expenses of the Underlying Funds in which it invests; (2) the Fund’s investment performance is directly tied to the performance of the Underlying Funds in which it invests. If one or more Underlying Funds fail to meet their investment objectives, the Fund’s performance will be negatively affected; (3) the Fund is subject to different levels and combinations of risk based on its actual allocation among the various asset classes and Underlying Funds. The potential impact of the risks related to an asset class depends on the size of the Fund’s investment allocation to it; (4) the Adviser's evaluations and allocation among asset classes and Underlying Funds may be incorrect; (5) the Adviser may add or delete Underlying Funds, or alter the Fund’s asset allocation, at its discretion. Changes to the Fund’s Underlying Funds or allocation (or the lack thereof) could affect both the level of risk and the potential for gain or loss; and (6) in selecting the Underlying Funds in which the Fund invests, the Adviser is subject to a conflict of interest because the Adviser is also the investment adviser to most, if not all, of the Underlying Funds. Although the Fund may invest a portion of its assets in unaffiliated Underlying Funds, there is no assurance that it will do so. To the extent that it is appropriate or suitable for a Fund's investment objective, the Adviser expects to invest in affiliated Underlying Funds without considering or canvassing the universe of unaffiliated Underlying Funds available, even though there may (or may not) be one or more comparable unaffiliated Underlying Funds. The Adviser receives advisory fees from affiliated Underlying Funds and, therefore, has an incentive to invest the Fund’s assets in affiliated Underlying Funds instead of unaffiliated Underlying Funds. In addition, the Adviser might have an interest in making an investment in an affiliated Underlying Fund, or in maintaining an existing investment in an affiliated Underlying Fund, in order to benefit that affiliated Underlying Fund (for example, by assisting the affiliated Underlying Fund in achieving or maintaining scale). Notwithstanding the foregoing, the Adviser has a fiduciary duty to the Fund and must act in the best interest of the Fund.
Nationwide Destination 2060 Fund | Exchange Traded Funds Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Exchange-traded funds risk – when the Fund invests in exchange-traded funds (“ETFs”), you will indirectly bear fees and expenses charged by the ETFs in addition to the Fund’s direct fees and expenses. In addition, the Fund will be affected by losses of the ETFs and the level of risk arising from the investment practices of the ETFs (such as the use of leverage by the ETFs). The Fund has no control over the investments and related risks taken by the ETFs in which it invests. Additionally, investments in ETFs are also subject to the following risks: (i) the market price of an ETF’s shares may trade above or below their net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted for a number of reasons.
Nationwide Destination 2060 Fund | Management Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Management risk – the Fund is subject to the risk that the methods and analyses employed by its investment adviser, or by the investment advisers or subadvisers to the Underlying Funds, will not produce the desired results. This could cause the Fund to lose value or its performance to lag those of relevant benchmarks or other funds with similar objectives.
Nationwide Destination 2060 Fund | Market Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Market risk – the risk that one or more markets in which an Underlying Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. This occurs due to numerous factors, including interest rates, the outlook for corporate profits, the health of the national and world economies, and the fluctuation of other securities markets around the world. These risks may be magnified if certain social, political, economic and other conditions and events (such as natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest or rapid technological developments such as artificial intelligence) adversely interrupt the global economy.
Nationwide Destination 2060 Fund | Equity Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Equity securities risk – stock markets are volatile. The price of an equity security fluctuates based on changes in a company’s financial condition and overall market and economic conditions.
Nationwide Destination 2060 Fund | Foreign Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Foreign securities risk – foreign securities often are more volatile, harder to price and less liquid than U.S. securities. The prices of foreign securities may be further affected by other factors, such as changes in the exchange rates between the U.S. dollar and the currencies in which the securities are traded.
Nationwide Destination 2060 Fund | Emerging Markets Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Emerging markets risk – emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets are considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. Since these markets are smaller than developed markets, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because the Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries are unreliable compared to developed markets. Companies in emerging market countries generally are subject to less stringent financial reporting, accounting and auditing standards than companies in more developed countries. In addition, information about such companies may be less available and reliable. Many emerging markets also have histories of political instability and abrupt changes in policies, and the ability to bring and enforce actions may be limited. Certain emerging markets also face other significant internal or external risks, including the risk of war, nationalization of assets, unexpected market closures and ethnic, religious and racial conflicts.
Nationwide Destination 2060 Fund | Smaller Company Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Smaller company risk – smaller companies are usually less stable in price and less liquid than larger, more established companies. Smaller companies are more vulnerable than larger companies to adverse business and economic developments and may have more limited resources. Therefore, they generally involve greater risk.
Nationwide Destination 2060 Fund | Fixed Income Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Fixed-income securities risk – investments in fixed-income securities, such as bonds, subject the Fund to interest rate risk, credit risk and prepayment and call risk, which may affect the value of your investment. Interest rate risk is the risk that the value of fixed-income securities will decline when interest rates rise. Prices of longer-term securities generally change more in response to interest rate changes than prices of shorter-term securities. To the extent an Underlying Fund invests a substantial portion of its assets in debt securities with longer-term maturities, rising interest rates are more likely to cause periods of increased volatility and redemptions, and may cause the value of the Fund’s investments to decline significantly. The Federal Reserve Board recently lowered interest rates following a period of consistent rate increases, though it is unclear if such lowering will continue. The interest earned on an Underlying Fund's investments in fixed-income securities may decline when prevailing interest rates fall. Declines in interest rates increase the likelihood that debt obligations will be pre-paid, which, in turn, increases these risks. The Fund is subject to the risk that the income generated by its investments in fixed-income securities will not keep pace with inflation. Recent and potential future changes in government policy may affect interest rates. Credit risk is the risk that the issuer of a bond may default if it is unable to pay interest or principal when due. If an issuer defaults, the Underlying Fund, and therefore the Fund, will lose money. Changes in a bond issuer’s credit rating or the market’s perceptions of an issuer’s creditworthiness also may affect the value of a bond. Prepayment and call risk is the risk that certain debt securities will be paid off by the issuer more quickly than anticipated. If this occurs, an Underlying Fund may be required to invest the proceeds in securities with lower yields.
Nationwide Destination 2060 Fund | Index Fund Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Index fund risk – an Underlying Fund that seeks to match the performance of an index does not use defensive strategies or attempt to reduce its exposure to poorly performing securities. Further, correlation between an Underlying Fund’s performance and that of the index is likely to be negatively affected by the Underlying Fund’s expenses, changes in the composition of the index, and the timing of purchase and redemption of Underlying Fund shares.
Nationwide Destination 2060 Fund | Derivatives Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Derivatives risk – derivatives may be volatile and may involve significant risks. The underlying security, commodity, measure or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Normally derivatives involve leverage, which means that their use can significantly magnify the effect of price movements of the underlying securities or reference measures, disproportionately increasing a Fund's or Underlying Fund's losses and reducing the Fund's or Underlying Fund's opportunities for gains. Some derivatives have the potential for unlimited loss, including a loss that may be greater than the amount invested. They also present default risks if the counterparty to a derivatives contract fails to fulfill its obligations to the Fund or Underlying Fund. Certain derivatives held by a Fund or Underlying Fund may be illiquid, making it difficult to close out an unfavorable position. Finally, the Fund's use of derivatives may cause the Fund to realize higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments.
Nationwide Destination 2060 Fund | Futures [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Futures – the prices of futures contracts typically are more volatile than those of stocks and bonds. Small movements in the values of the assets or measures of underlying futures contracts can cause disproportionately larger losses to the Fund or an Underlying Fund. While futures may be more liquid than other types of derivatives, they may experience periods when they are less liquid than stocks, bonds or other investments.
Nationwide Destination 2060 Fund | Options [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Options – purchasing and writing put and call options are highly specialized activities and entail greater-than-ordinary investment risks. Investments in options are considered speculative. An option is an agreement that, for a premium payment or fee, gives the option holder (the purchaser) the right but not the obligation to buy (a “call option”) or sell (a “put option”) the underlying security or futures contract (or settle for cash an amount based on an underlying asset, rate or index) at a specified price (the “exercise price”) during a period of time or on a specified date. When the Underlying Fund writes (sells) an option, it profits if the option expires unexercised, because it retains the premium the buyer of the option paid. However, if the Underlying Fund writes a call option, it incurs the risk that the market price of the underlying security or futures contract will increase above the option's exercise price. If this occurs, the option could be exercised and the Underlying Fund would be forced to sell the underlying security or futures contract at a lower price than its current market value. If the Underlying Fund writes a put option, it incurs the risk that the market value of the underlying security or futures contract will decrease below the option's exercise price. If this occurs, the option could be exercised and the Underlying Fund would be forced to buy the underlying security or futures contract at a higher price than its current market value. When the Underlying Fund purchases an option, it will lose the premium paid for the option if the price of the underlying security or futures contract decreases or remains the same (in the case of a call option) or increases or remains the same (in the case of a put option). If an option purchased by the Underlying Fund were permitted to expire without being sold or exercised, its premium would represent a loss to the Fund.
Nationwide Destination 2060 Fund | Swaps [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Swaps – using swaps can involve greater risks than if an Underlying Fund were to invest directly in the underlying securities or assets. Because swaps often involve leverage, their use can significantly magnify the effect of price movements of the underlying securities or reference measures, disproportionately increasing an Underlying Fund's losses and reducing an Underlying Fund's opportunities for gains. Currently there are few central exchanges or markets for swap contracts, and therefore they may be less liquid than exchange-traded instruments. If a swap counterparty fails to meet its obligations under the contract, the Underlying Fund will lose money.
Nationwide Destination 2060 Fund | Limited Portfolio Holdings Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Limited portfolio holdings risk – because the Fund may hold large positions in an Underlying Fund, an increase or decrease in the value of such securities will have a greater impact on the Fund’s value and total return.
Nationwide Destination 2060 Fund | Retirement Goal Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Retirement goal risk – the assumption that an investor will retire at the age of 65 is only an approximate guide, and is not necessarily intended to reflect the specific age at which an investor should retire or start withdrawing retirement assets. An investor may have different retirement needs than the allocation model anticipates.
Nationwide Destination 2060 Fund | Short Sales Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Short sales risk – the Fund will suffer a loss if an Underlying Fund takes a short position in a security and the price of the security rises rather than falls. Short positions expose the Underlying Fund to the risk that it will be required to cover the short position at a time when the security has appreciated in value, thus resulting in a loss to the Fund. The Fund’s investment performance also will suffer if an Underlying Fund is required to close out a short position earlier than it had intended. In addition, an Underlying Fund will be subject to expenses related to short positions that typically are not associated with investing in securities directly (for example, costs of borrowing and margin account maintenance costs associated with the Underlying Fund’s open short positions). These expenses will impact negatively the performance of the Fund. Short positions introduce more risk to an Underlying Fund than long positions because the maximum sustainable loss on a security purchased (held long) is limited to the amount paid for the security plus the transaction costs, whereas there is no maximum attainable price of the security held in a short position. Therefore, in theory, securities held short present unlimited risk.
