| 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.

| 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.
|
| Schwab Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | Money Market Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Money Market Fund Risk. The 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | Emerging Markets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Risk. Emerging market countries may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. Emerging market countries often have less uniformity in accounting, auditing, financial reporting and recordkeeping requirements and greater risk associated with the custody of securities. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in developed countries. As a result, there may be an increased risk of illiquidity and price volatility associated with an underlying fund’s investments in emerging market countries, which may be magnified by currency fluctuations relative to the U.S. dollar, and, at times, it may be difficult to value such investments.
|
| Schwab Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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. However, these risks are less severe when the underlying fund uses derivatives for hedging rather than to enhance the underlying fund’s returns or as a substitute for a position or security.
|
| Schwab Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 underlying fund.
|
| Schwab Target 2010 Index Fund | Schwab Target 2010 Index Fund | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Concentration Risk. To the extent that an underlying fund’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector 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 or asset class.
|
| Schwab Target 2010 Index Fund | Schwab Target 2010 Index Fund | Investment Style Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Style Risk. Certain underlying funds seek to track the performance of various segments of the stock market, as measured by their respective indices. Such underlying funds follow these stocks during upturns as well as downturns. Because of their indexing strategy, these underlying funds do not take steps to reduce market exposure or to lessen the effects of a declining market. In addition, because of an underlying fund’s expenses, the underlying fund’s performance is normally below that of the index. Errors relating to an index may occur from time to time and may not be identified by the underlying fund’s index provider for a period of time. In addition, market disruptions could cause delays in an underlying fund’s index’s rebalancing schedule. Such errors and/or market disruptions may result in losses for an underlying fund.
|
| Schwab Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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 Target 2010 Index Fund | Schwab Target 2010 Index Fund | 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.

As a result, there may be an increased risk of illiquidity and price volatility associated with an underlying fund’s investments in emerging market countries, which may be magnified by currency fluctuations relative to the U.S. dollar, and, at times, it may be difficult to value such investments.

| 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. However, these risks are less severe when the underlying fund uses derivatives for hedging rather than to enhance the underlying fund’s returns or as a substitute for a position or security.

| 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.

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.

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.

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.

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.

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. However, these risks are less severe when the underlying fund uses derivatives for hedging rather than to enhance the underlying fund’s returns or as a substitute for a position or security.

| 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 underlying fund.

| Risk [Text Block] | Concentration Risk. To the extent that an underlying fund’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector 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 or asset class.

| Risk [Text Block] | Investment Style Risk. Certain underlying funds seek to track the performance of various segments of the stock market, as measured by their respective indices. Such underlying funds follow these stocks during upturns as well as downturns. Because of their indexing strategy, these underlying funds do not take steps to reduce market exposure or to lessen the effects of a declining market. In addition, because of an underlying fund’s expenses, the underlying fund’s performance is normally below that of the index. Errors relating to an index may occur from time to time and may not be identified by the underlying fund’s index provider for a period of time. In addition, market disruptions could cause delays in an underlying fund’s index’s rebalancing schedule. Such errors and/or market disruptions may result in losses for an underlying fund.

| 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.

| 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.

| 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] | 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.

| Risk [Text Block] | Money Market Fund Risk. The 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] | 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.

| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Risk. Emerging market countries may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. Emerging market countries often have less uniformity in accounting, auditing, financial reporting and recordkeeping requirements and greater risk associated with the custody of securities. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in developed countries. As a result, there may be an increased risk of illiquidity and price volatility associated with an underlying fund’s investments in emerging market countries, which may be magnified by currency fluctuations relative to the U.S. dollar, and, at times, it may be difficult to value such investments.
