Schwab Monthly Income Fund - Target Payout | Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] The fund is subject to risks, any of which could cause an investor to lose money.
Schwab Monthly Income Fund - Target Payout | Asset Allocation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Asset Allocation Risk. The fund is subject to the risk that the selection of the underlying funds and the allocation of the fund’s assets among the various asset classes and market segments may cause the fund to underperform other funds with a similar investment objective. The fund is not managed to maximize tax efficiency for taxable shareholder accounts. Investors should consider whether the fund is an appropriate investment in light of their current financial position and retirement needs.
Schwab Monthly Income Fund - Target Payout | Conflicts of Interest Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Conflicts of Interest Risk. The investment adviser’s authority to select and substitute underlying funds from a variety of affiliated and unaffiliated mutual funds and ETFs may create a conflict of interest because the fees paid to it and its affiliates by some underlying funds are higher than the fees paid by other underlying funds. The investment adviser also may have an incentive to select an affiliated underlying fund for other reasons, including to increase assets under management or to support new investment strategies. In addition, other conflicts of interest may exist where the best interests of the affiliated underlying fund may not be aligned with those of the fund. However, the investment adviser is a fiduciary to the fund and is legally obligated to act in the fund’s best interests when selecting underlying funds.
Schwab Monthly Income Fund - Target Payout | Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Market Risk. Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions, tariffs and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. As with any investment whose performance is tied to these markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.
Schwab Monthly Income Fund - Target Payout | ETF Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ETF Risk. When the fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. In addition, lack of liquidity in the market for an ETF’s shares can result in its value being more volatile than the underlying portfolio of securities.
Schwab Monthly Income Fund - Target Payout | Structural Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Structural Risk. The fund’s monthly income payments will be made from fund assets and will reduce the amount of assets available for investment by the fund. Even if the fund’s capital grows over time, such growth may be insufficient to enable the fund to maintain the amount of its targeted annual payout and targeted monthly income payments. The fund’s investment losses may reduce the amount of future cash income payments an investor will receive from the fund. The dollar amount of the fund’s monthly income payments could vary substantially from one year to the next and over time depending on several factors, including the performance of
the financial markets in which the fund invests, the allocation of fund assets across different asset classes and investments, the performance of the fund’s investment strategies, and the amount and timing of prior distributions by the fund. It is also possible for payments to go down substantially from one year to the next and over time depending on the timing of an investor’s investments in the fund. Any redemptions will proportionately reduce the amount of future cash income payments to be received from the fund. There is no guarantee that the fund will make monthly income payments to its shareholders or, if made, that the fund’s monthly income payments to shareholders will remain at a fixed amount.
Schwab Monthly Income Fund - Target Payout | Managed Payout Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Managed Payout Risk. Because the fund is expected to make monthly payments regardless of investment performance, the amount of the fund’s distributions in respect of any period often will exceed the amount of the fund’s income and gains for that period. In that case, some or all of the fund’s distributions may constitute a return of capital to shareholders. It is possible for the fund to suffer substantial investment losses and simultaneously experience additional asset reductions as a result of its payments to shareholders under the managed payout policy. In addition, in order to make the payments called for under the fund’s managed payout policy, the fund may have to sell portfolio securities at a time when it would not otherwise do so.
A return of capital distribution generally will not be taxable but will decrease the shareholder’s cost basis in the shares of the fund and will result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the fund as capital assets. A distribution constituting a return of capital is not a distribution of income or capital gains earned by the fund, and should not be confused with the fund’s “yield” or “income.”
Schwab Monthly Income Fund - Target Payout | Direct Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Direct Investment Risk. The fund may invest directly in cash, cash equivalents and equity and fixed-income securities, including money market securities, to maintain its allocations. The fund’s direct investment in these securities is subject to the same or similar risks as an underlying fund’s investment in the same securities.
Schwab Monthly Income Fund - Target Payout | Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Portfolio Turnover Risk. High portfolio turnover may result in the fund paying higher levels of transaction costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the fund’s performance to be less than expected.
Schwab Monthly Income Fund - Target Payout | Underlying Fund Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Underlying Fund Investment Risk. Before investing in the fund, investors should assess the risks associated with the underlying funds in which the fund may invest, which include any combination of the risks described below.
Schwab Monthly Income Fund - Target Payout | Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Investment Risk. The fund may experience losses with respect to its investment in an underlying fund. Further, there is no guarantee that an underlying fund will be able to achieve its objective.
Schwab Monthly Income Fund - Target Payout | Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Management Risk. Certain underlying funds are actively managed mutual funds. An underlying fund’s adviser applies its own investment techniques and risk analyses in making
investment decisions for the fund, but there can be no guarantee that they will produce the desired results or cause the underlying fund to meet its objectives.
Schwab Monthly Income Fund - Target Payout | Equity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Equity Risk. The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities market as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.
Schwab Monthly Income Fund - Target Payout | Market Capitalization Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
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, an underlying fund’s performance could be impacted.
Schwab Monthly Income Fund - Target Payout | Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Concentration Risk. To the extent that an underlying fund’s or the index’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector, country or asset class, the underlying fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more vulnerable to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector, country or asset class.
Schwab Monthly Income Fund - Target Payout | Fixed-Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Fixed-Income Risk. Interest rates rise and fall over time, which will affect an underlying fund’s yield and share price. A change in a central bank’s monetary policy or economic conditions, among other things, may result in a change in interest rates. A rise in interest rates could cause an underlying fund’s share price to fall. The credit quality of a portfolio investment could also cause an underlying fund’s share price to fall. An underlying fund could lose money if the issuer or guarantor of a portfolio investment or the counterparty to a derivatives contract fails to make timely principal or interest payments or otherwise honor its obligations. Fixed-income securities may be paid off earlier or later than expected. Either situation could cause an underlying fund to hold securities paying lower-than-market rates of interest, which could hurt an underlying fund’s yield or share price. Below investment-grade bonds (junk bonds) involve greater credit risk, are more volatile, involve greater risk of price declines and may be more susceptible to economic downturns than investment-grade securities.
Schwab Monthly Income Fund - Target Payout | Foreign Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Foreign Investment Risk. An underlying fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); the imposition of economic sanctions or other government restrictions; differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. These risks may negatively impact the value or liquidity of an underlying fund’s investments, and could impair the underlying fund’s ability to meet its investment objective or invest in accordance with its
investment strategy. There is a risk that investments in securities denominated in, and/or receiving revenues in, foreign currencies will decline in value relative to the U.S. dollar.
Schwab Monthly Income Fund - Target Payout | High-Yield Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
High-Yield Risk. An underlying fund’s investments in high-yield securities and unrated securities of similar credit quality (junk bonds) are subject to greater levels of credit and liquidity risks, and may be more volatile than higher-rated securities. High-yield securities are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments.
Schwab Monthly Income Fund - Target Payout | Floating Rate Loan Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Floating Rate Loan Risk. Transactions involving floating rate loans may have significantly longer settlement periods than more traditional bond investments (settlement can take longer than 7 days) and often involve borrowers whose financial condition is troubled or highly leveraged, which increases the risk that the underlying fund may not receive its proceeds in a timely manner and that the underlying fund may incur unexpected losses in order to pay redemption proceeds to its shareholders. In addition, loans are not registered or regulated under the federal securities laws like most stocks and bonds, so investors in loans have less protection against improper practices than investors in registered securities. While a loan assignment typically transfers all legal and economic rights to the buyer, a loan participation typically allows the seller to maintain legal title to the loan, meaning the buyer of a loan participation generally has no direct rights against the borrower and is exposed to credit risk of both the borrower and seller of the participation.
Schwab Monthly Income Fund - Target Payout | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Derivatives Risk. An underlying fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. An underlying fund’s use of derivatives could reduce the underlying fund’s performance, increase its volatility and cause the underlying fund to lose more than the initial amount invested. In addition, investments in derivatives may involve leverage, which means a small percentage of assets invested in derivatives can have a disproportionately large impact on an underlying fund.
Schwab Monthly Income Fund - Target Payout | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Leverage Risk. Certain underlying fund transactions, such as derivatives transactions, short sales, reverse repurchase agreements, and mortgage dollar rolls, may give rise to a form of leverage and may expose an underlying fund to greater risk. Leverage tends to magnify the effect of any decrease or increase in the value of an underlying fund’s portfolio securities, which means even a small amount of leverage can have a disproportionately large impact on the fund.
Schwab Monthly Income Fund - Target Payout | Money Market Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Money Market Fund Risk. A fund may invest in underlying money market funds that seek to maintain a stable $1.00 net asset value. Although an underlying money market fund seeks to maintain a stable $1.00 net asset value, it is possible to lose money by investing in such a money market fund. In addition, money market funds are not designed to offer capital appreciation. Certain underlying money market funds may impose a fee upon the sale of shares under certain circumstances.
Schwab Monthly Income Fund - Target Payout | Tracking Error and Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Tracking Error and Correlation Risk. Each underlying index fund seeks to track the performance of its respective index, although it may not be successful in doing so. Further, there can
be no guarantee that the underlying index fund will achieve a high degree of correlation between the underlying index fund’s performance and that of its index. The correlation between the performance of an underlying fund and that of its index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant. If an underlying fund utilizes a sampling approach, it may not track the return of the index as well as it would if the underlying fund purchased all of the securities in the index.
Schwab Monthly Income Fund - Target Payout | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Liquidity Risk. An underlying fund may be unable to sell certain securities, such as illiquid securities, readily at a favorable time or price, or the underlying fund may have to sell them at a loss.

Schwab Monthly Income Fund - Target Payout | Securities Lending Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Securities Lending Risk. Certain underlying funds engage in securities lending, which involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent.
Schwab Monthly Income Fund - Target Payout | Real Estate Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Real Estate Investment Risk. An underlying fund in which the fund may invest may have a policy of concentrating its investments in real estate companies and companies related to the real estate industry. As such, an underlying fund is subject to risks associated with the direct ownership of real estate securities and the fund’s investment in such an underlying fund is subject to risks associated with the direct ownership of real estate securities and an investment in the underlying fund will be closely linked to the performance of the real estate markets. These risks include, among others, declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets; defaults by borrowers or tenants, particularly during an economic downturn; and changes in interest rates.
Schwab Monthly Income Fund - Target Payout | Real Estate Investment Trusts (REITs) Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Real Estate Investment Trusts (REITs) Risk. An underlying fund’s investments in REITs will be subject to the risks associated with the direct ownership of real estate, including fluctuations in the value of underlying properties, defaults by borrowers or tenants, access to capital, changes in interest rates and risks related to general or local economic conditions. REITs are also subject to certain additional risks, for example, REITs may have their investments in relatively few properties, a small geographic area or a single property type. In addition, REITs have their own expenses, and an underlying fund will bear a proportionate share of those expenses.
Schwab Monthly Income Fund - Target Payout | Underlying Fund Investment Risk Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Portfolio Turnover Risk. Certain of the underlying funds may buy and sell portfolio securities actively. If they do, their portfolio turnover rate and transaction costs will rise, which may lower the underlying fund’s performance and may increase the likelihood of capital gains distributions.

Asset Allocation Risk. The fund is subject to the risk that the selection of the underlying funds and the allocation of the fund’s assets among the various asset classes and market segments may cause the fund to underperform other funds with a similar investment objective. The fund is not managed to maximize tax efficiency for taxable shareholder accounts. Investors should consider whether the fund is an appropriate investment in light of their current financial position and retirement needs.

Prospectus [Line Items]  
Risk [Text Block]
Conflicts of Interest Risk. The investment adviser’s authority to select and substitute underlying funds from a variety of affiliated and unaffiliated mutual funds and ETFs may create a conflict of interest because the fees paid to it and its affiliates by some underlying funds are higher than the fees paid by other underlying funds. The investment adviser also may have an incentive to select an affiliated underlying fund for other reasons, including to increase assets under management or to support new investment strategies. In addition, other conflicts of interest may exist where the best interests of the affiliated underlying fund may not be aligned with those of the fund. However, the investment adviser is a fiduciary to the fund and is legally obligated to act in the fund’s best interests when selecting underlying funds.

Market Risk. Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions, tariffs and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. As with any investment whose performance is tied to these markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.

ETF Risk. When the fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. In addition, lack of liquidity in the market for an ETF’s shares can result in its value being more volatile than the underlying portfolio of securities.
Schwab Monthly Income Fund - Income Payout | Structural Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Structural Risk. The fund’s monthly income payments will be made from fund assets and will reduce the amount of assets available for investment by the fund. Even if the fund’s capital grows over time, such growth may be insufficient to enable the fund to maintain the
amount of its targeted annual payout and targeted monthly income payments. The fund’s investment losses may reduce the amount of future cash income payments an investor will receive from the fund. The dollar amount of the fund’s monthly income payments could vary substantially from one year to the next and over time depending on several factors, including the performance of the financial markets in which the fund invests, the allocation of fund assets across different asset classes and investments, the performance of the fund’s investment strategies, and the amount and timing of prior distributions by the fund. It is also possible for payments to go down substantially from one year to the next and over time depending on the timing of an investor’s investments in the fund. Any redemptions will proportionately reduce the amount of future cash income payments to be received from the fund. There is no guarantee that the fund will make monthly income payments to its shareholders or, if made, that the fund’s monthly income payments to shareholders will remain at a fixed amount.

Equity Risk. The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Risk [Text Block]
Concentration Risk. To the extent that an underlying fund’s or the index’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector, country or asset class, the underlying fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more vulnerable to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector, country or asset class.
Schwab Monthly Income Fund - Income Payout | Fixed-Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Fixed-Income Risk. Interest rates rise and fall over time, which will affect an underlying fund’s yield and share price. A change in a central bank’s monetary policy or economic conditions, among other things, may result in a change in interest rates. A rise in interest rates could cause an underlying fund’s share price to fall. The credit quality of a portfolio investment could also cause an underlying fund’s share price to fall. An underlying fund could lose money if the issuer or guarantor of a portfolio investment or the counterparty to a derivatives contract fails to make timely principal or interest payments or otherwise honor its obligations. Fixed-income securities may be paid off earlier or later than expected. Either situation could cause an underlying fund to hold securities paying lower-than-market rates of interest, which could hurt an underlying fund’s yield or share price. Below investment-grade bonds (junk bonds) involve greater credit risk, are more volatile, involve greater risk of price declines and may be more susceptible to economic downturns than investment-grade securities.

Risk [Text Block]
Foreign Investment Risk. An underlying fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); the imposition of economic sanctions or other government restrictions; differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. These risks may negatively impact the value or liquidity of an underlying fund’s investments, and could impair the underlying fund’s ability to meet its investment objective or invest in accordance with its investment strategy. There is a risk that investments in securities denominated in, and/or receiving revenues in, foreign currencies will decline in value relative to the U.S. dollar.

High-Yield Risk. An underlying fund’s investments in high-yield securities and unrated securities of similar credit quality (junk bonds) are subject to greater levels of credit and liquidity risks, and may be more volatile than higher-rated securities. High-yield securities are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments.
Schwab Monthly Income Fund - Income Payout | Floating Rate Loan Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Floating Rate Loan Risk. Transactions involving floating rate loans may have significantly longer settlement periods than more traditional bond investments (settlement can take longer than 7 days) and often involve borrowers whose financial condition is troubled or highly leveraged, which increases the risk that the underlying fund may not receive its proceeds in a timely manner
and that the underlying fund may incur unexpected losses in order to pay redemption proceeds to its shareholders. In addition, loans are not registered or regulated under the federal securities laws like most stocks and bonds, so investors in loans have less protection against improper practices than investors in registered securities. While a loan assignment typically transfers all legal and economic rights to the buyer, a loan participation typically allows the seller to maintain legal title to the loan, meaning the buyer of a loan participation generally has no direct rights against the borrower and is exposed to credit risk of both the borrower and seller of the participation.

Risk [Text Block]
Derivatives Risk. An underlying fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. An underlying fund’s use of derivatives could reduce the underlying fund’s performance, increase its volatility and cause the underlying fund to lose more than the initial amount invested. In addition, investments in derivatives may involve leverage, which means a small percentage of assets invested in derivatives can have a disproportionately large impact on an underlying fund.
Schwab Monthly Income Fund - Income Payout | Leverage Risk [Member]

Risk [Text Block]
Leverage Risk. Certain underlying fund transactions, such as derivatives transactions, short sales, reverse repurchase agreements, and mortgage dollar rolls, may give rise to a form of leverage and may expose an underlying fund to greater risk. Leverage tends to magnify the effect of any decrease or increase in the value of an underlying fund’s portfolio securities, which means even a small amount of leverage can have a disproportionately large impact on the fund.

Money Market Fund Risk. A fund may invest in underlying money market funds that seek to maintain a stable $1.00 net asset value. Although an underlying money market fund seeks to maintain a stable $1.00 net asset value, it is possible to lose money by investing in such a money market fund. In addition, money market funds are not designed to offer capital appreciation. Certain underlying money market funds may impose a fee upon the sale of shares under certain circumstances.

Risk [Text Block]
Tracking Error and Correlation Risk. Each underlying index fund seeks to track the performance of its respective index, although it may not be successful in doing so. Further, there can be no guarantee that the underlying index fund will achieve a high degree of correlation between the underlying index fund’s performance and that of its index. The correlation between the performance of an underlying fund and that of its index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant. If an underlying fund utilizes a sampling approach, it may not track the return of the index as well as it would if the underlying fund purchased all of the securities in the index.

Real Estate Investment Risk. An underlying fund in which the fund may invest may have a policy of concentrating its investments in real estate companies and companies related to the real estate industry. As such, an underlying fund is subject to risks associated with the direct ownership of real estate securities and the fund’s investment in such an underlying fund is subject to risks associated with the direct ownership of real estate securities and an investment in the underlying fund will be closely linked to the performance of the real estate markets. These risks include, among others, declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets; defaults by borrowers or tenants, particularly during an economic downturn; and changes in interest rates.

An underlying fund’s investments in REITs will be subject to the risks associated with the direct ownership of real estate, including fluctuations in the value of underlying properties, defaults by borrowers or tenants, access to capital, changes in interest rates and risks related to general or local economic conditions. REITs are also subject to certain additional risks, for example, REITs may have their investments in relatively few properties, a small geographic area or a single property type. In addition, REITs have their own expenses, and an underlying fund will bear a proportionate share of those expenses.
