This example is intended to help you compare the cost of investing in the fund with the cost of investing in other 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 time periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. The figures are based on total annual fund operating expenses (including AFFE) after any expense reduction. Your actual costs may be higher or lower.

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock
The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio
turnover 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 the 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 26% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
The fund seeks to achieve its investment objective by investing primarily in affiliated Schwab exchange-traded funds (ETFs). The fund may also invest in affiliated Schwab mutual funds, and unaffiliated third party ETFs and mutual funds (all such ETFs and mutual funds referred to herein as the “underlying funds”). The fund has a policy to invest, under normal circumstances, at least 80% of its assets (net assets, including, for this purpose, any borrowings for investment purposes) in underlying funds that are managed to seek investment returns that track particular market indices. The fund will notify its shareholders at least 60 days before changing this policy. The fund invests in the underlying funds in accordance with its target portfolio allocation. These underlying funds invest their assets directly in equity, fixed income, cash and cash equivalents (including money market funds) in accordance with their own investment objectives and policies. The fund is managed based on the specific retirement date (target date) included in its name and assumes a retirement age of 65. The target date refers to the approximate year an investor in the fund would plan to retire and likely would stop making new investments in the fund. The fund is designed for an investor who retired at or about the year 2010 and plans to withdraw the value of the investor’s account in the fund gradually after retirement. As described below, the adviser will continue to modify the fund’s target asset allocation for 20 years beyond the target date.
The fund’s target asset allocation will be adjusted annually based on the adviser’s asset allocation strategy; however, the adviser reserves the right to modify the fund’s target asset allocations from time to time should circumstances warrant a change. In general, the fund’s allocation to equity securities decreased and its allocation to fixed-income securities increased as the fund approached its target date. The fund’s asset allocation as of February 1, 2025 (the most recent annual adjustment of the fund’s target asset allocations) was approximately 34.5% equity securities, 62.3% fixed-income securities, and 3.2% cash and cash equivalents (including money market funds). The fund will continue to reduce its allocation to equity securities for 20 years beyond the fund’s stated target date. At such time, the fund’s asset allocation will remain fixed at approximately 28.0% equity securities, 68.0% fixed-income securities, and 4.0% cash and cash equivalents (including money market funds).
In addition to the strategic annual adjustment of the fund’s target asset allocation, the adviser may adjust the fund’s underlying
fund allocations within a particular asset class based on the following considerations, including, but not limited to, market trends, its outlook for a given market capitalization, and the underlying funds’ performance in various market conditions. Accordingly, the fund’s allocation to a particular underlying fund may increase or decrease throughout the year. Within the equity asset class, the fund will have exposure to one or more “style classes.” For example, the style classes include domestic large-cap equity, domestic small-cap equity, and international equity. The adviser may adjust the fund’s allocation to a particular style class based on the following considerations: market trends, its outlook for a given style class, and the style classes’ performance in various market conditions. Accordingly, the fund’s allocation to a particular style class within the equity asset class may increase or decrease throughout the year.
The fund intends to invest in a combination of underlying funds; however, the fund may invest directly in equity and fixed-income securities and money market securities. For temporary defensive purposes during unusual economic or market conditions or for liquidity purposes, the fund may invest up to 100% of its assets directly in cash, money market instruments, repurchase agreements and other short-term obligations. When the fund engages in such activities, it may not achieve its investment objective.

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] oef_RiskTextBlock
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 | Fixed-Income Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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] oef_RiskTextBlock
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.

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.

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] oef_RiskTextBlock
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] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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] oef_RiskTextBlock
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]

Risk [Text Block] oef_RiskTextBlock
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.
