Schwab Monthly Income Fund - Moderate Payout

Schwab^® Monthly Income Fund – Moderate Payout

Investment Objective

The fund seeks to provide current income and,

as a secondary investment objective, capital appreciation.

Fund Fees and Expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	Schwab Monthly Income Fund - Moderate Payout Schwab Monthly Income Fund - Moderate Payout USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a % of the value of your investment)

Annual Fund Operating Expenses	Schwab Monthly Income Fund - Moderate Payout Schwab Monthly Income Fund - Moderate Payout
Management fees	none
Distribution (12b-1) fees	none
Other expenses	0.20%
Acquired fund fees and expenses (AFFE)	0.58%	[1]
Total annual fund operating expenses	0.78%	[1]
Less expense reduction	(0.20%)
Total annual fund operating expenses (including AFFE) after expense reduction	0.58%	[1],[2]

Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those 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 expense reduction. The expenses would be the same whether you stayed in the fund or sold your shares at the end of each period. Your actual costs may be higher or lower.

Expense Example	1 Year	3 Years	5 Years	10 Years

Portfolio Turnover

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 41% of the average value of its portfolio.

Principal Investment Strategies

The fund seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds^® and Laudus Funds (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds.

The fund intends to invest in a combination of underlying funds; however, the fund may invest directly in equity and fixed income securities, cash and cash equivalents (including money market securities), exchange-traded funds (ETFs) and nonproprietary mutual funds.

The fund intends to allocate investments among various asset classes such as equity, fixed income and cash and cash equivalents (including money market funds). The fund has its own distinct asset allocation strategy that is designed to accommodate the fund's targeted annual payout percentage while taking into account the fund's specific risk tolerances and desired level of capital appreciation. The fund's target asset allocation is not fixed, and the fund has the flexibility to move within the following asset allocation ranges (under normal market conditions) at the discretion of the investment adviser: 20%-60% equity; 40%-70% fixed income; and 0%-10% cash and cash equivalents (including money market funds). Market appreciation or depreciation may cause the fund to be temporarily outside these ranges.

The fund is designed to offer investors a targeted annual payout of 3-4%. The targeted annual payout for the fund is based on historic yield environments over a ten year period. The fund's actual annual payout could be higher or lower than the targeted annual payout based on the interest rate environment and other market factors occurring during that year. The fund's anticipated annual payout during a low interest rate environment is expected to be 1-3% and, during a high interest rate environment, is expected to be 3-6%. The fund intends to make twelve monthly distributions to shareholders on or about the 15th calendar day of each month. The amounts distributed to shareholders are not fixed and may not be the same each month. Although it cannot be guaranteed by the fund, the fund does not expect to make distributions that will be treated as return of capital.

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.

Principal Risks

The fund is subject to risks, any of which could cause an investor to lose money. The fund's principal risks include:

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.

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. 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.

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.

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.

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.

• 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.

• 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.

• 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.

• 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.

• 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 improving economic conditions, among other things, may result in an increase in interest rates. A sharp rise in interest rates could cause an underlying fund to lose value. 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 the fund's yield or share price. Below investment-grade bonds (junk bonds) involve greater risks than investment-grade securities.

• 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.

• 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 volatility, and could 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.

• Leverage Risk. Certain underlying fund transactions, such as derivatives, 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. The fund may invest in underlying money market funds that either seek to maintain a stable $1 net asset value ("stable share price money market funds") or that have a share price that fluctuates ("variable share price money market funds"). Although an underlying stable share price money market fund seeks to maintain a stable $1 net asset value, it is possible to lose money by investing in such a money market fund. Because the share price of an underlying variable share price money market fund will fluctuate, when the fund sells the shares it owns they may be worth more or less than what the fund originally paid for them. In addition, neither type of money market fund is designed to offer capital appreciation. Certain underlying money market funds may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if such fund's liquidity falls below required minimums.

• 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.

• ETF Risk. When an underlying 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.

• 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.

• 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.

• Mortgage-Backed and Mortgage Pass-Through Securities Risk. Certain of the mortgage-backed securities in which an underlying fund may invest are not backed by the full faith and credit of the U.S. government and there can be no assurance that the U.S. government would provide financial support where it was not obligated to do so. Mortgage-backed securities tend to increase in value less than other debt securities when interest rates decline, but are subject to similar or greater risk of decline in market value during periods of rising interest rates. Transactions in mortgage pass-through securities primarily occur through to be announced (TBA) transactions. Default by or bankruptcy of a counterparty to a TBA transaction would expose an underlying fund to possible losses.

• 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.

For more information on the risks of investing in the fund and the underlying funds, please see the “Fund Details” section in the prospectus.

The after-tax figures reflect the highest individual federal income tax rates in effect during the period and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation. In addition, after-tax returns are not relevant if you hold your fund shares through a tax-deferred arrangement, such as a 401(k) plan, an individual retirement account (IRA) or other tax-advantaged account.

[1] Acquired fund fees and expenses (AFFE) are based on estimated amounts for the current fiscal period. AFFE reflect fees and expenses incurred indirectly by the fund through its investments in the underlying funds. The total annual fund operating expenses in the fee table may differ from the expense ratios in the fund’s “Financial Highlights” that include only the fund’s direct operating expenses and not AFFE.

[2] The investment adviser and its affiliates have agreed to limit the total annual fund operating expenses (excluding interest, taxes and certain non-routine expenses) of the fund to 0.00% for so long as the investment adviser serves as the adviser to the fund. This agreement may only be amended or terminated with the approval of the fund’s Board of Trustees. This agreement is limited to the fund’s direct operating expenses and does not apply to AFFE.

[1] The Moderate Payout Composite Index is a custom blended index developed by CSIM based on a comparable portfolio asset allocation. Effective April 1, 2013, the Moderate Payout Composite Index is composed of 28.50% S&P 500 Index, 11.87% MSCI EAFE (Net) Index, 7.13% FTSE EPRA/NAREIT Global Index (Net), 30.30% Bloomberg Barclays U.S. Aggregate Bond Index, 20.20% Bloomberg Barclays U.S. Intermediate Aggregate Bond Index, and 2.00% Bloomberg Barclays U.S. Treasury Bills: 1-3 Months. Prior to April 1, 2013, the Moderate Payout Composite Index was composed of 40% S&P 500 Index and 60% Bloomberg Barclays U.S. Aggregate Bond Index.

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. 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 improving economic conditions, among other things, may result in an increase in interest rates. A sharp rise in interest rates could cause an underlying fund to lose value. 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 the fund's yield or share price. Below investment-grade bonds (junk bonds) involve greater risks than investment-grade securities. 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. 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 volatility, and could 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. Leverage Risk. Certain underlying fund transactions, such as derivatives, 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. The fund may invest in underlying money market funds that either seek to maintain a stable $1 net asset value ("stable share price money market funds") or that have a share price that fluctuates ("variable share price money market funds"). Although an underlying stable share price money market fund seeks to maintain a stable $1 net asset value, it is possible to lose money by investing in such a money market fund. Because the share price of an underlying variable share price money market fund will fluctuate, when the fund sells the shares it owns they may be worth more or less than what the fund originally paid for them. In addition, neither type of money market fund is designed to offer capital appreciation. Certain underlying money market funds may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if such fund's liquidity falls below required minimums. 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. ETF Risk. When an underlying 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. 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. 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. Mortgage-Backed and Mortgage Pass-Through Securities Risk. Certain of the mortgage-backed securities in which an underlying fund may invest are not backed by the full faith and credit of the U.S. government and there can be no assurance that the U.S. government would provide financial support where it was not obligated to do so. Mortgage-backed securities tend to increase in value less than other debt securities when interest rates decline, but are subject to similar or greater risk of decline in market value during periods of rising interest rates. Transactions in mortgage pass-through securities primarily occur through to be announced (TBA) transactions. Default by or bankruptcy of a counterparty to a TBA transaction would expose an underlying fund to possible losses. 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. For more information on the risks of investing in the fund and the underlying funds, please see the “Fund Details” section in the prospectus.

[1] Acquired fund fees and expenses (AFFE) are based on estimated amounts for the current fiscal period. AFFE reflect fees and expenses incurred indirectly by the fund through its investments in the underlying funds. The total annual fund operating expenses in the fee table may differ from the expense ratios in the fund’s “Financial Highlights” that include only the fund’s direct operating expenses and not AFFE.

[2] The investment adviser and its affiliates have agreed to limit the total annual fund operating expenses (excluding interest, taxes and certain non-routine expenses) of the fund to 0.00% for so long as the investment adviser serves as the adviser to the fund. This agreement may only be amended or terminated with the approval of the fund’s Board of Trustees. This agreement is limited to the fund’s direct operating expenses and does not apply to AFFE.

[3] The Moderate Payout Composite Index is a custom blended index developed by CSIM based on a comparable portfolio asset allocation. Effective April 1, 2013, the Moderate Payout Composite Index is composed of 28.50% S&P 500 Index, 11.87% MSCI EAFE (Net) Index, 7.13% FTSE EPRA/NAREIT Global Index (Net), 30.30% Bloomberg Barclays U.S. Aggregate Bond Index, 20.20% Bloomberg Barclays U.S. Intermediate Aggregate Bond Index, and 2.00% Bloomberg Barclays U.S. Treasury Bills: 1-3 Months. Prior to April 1, 2013, the Moderate Payout Composite Index was composed of 40% S&P 500 Index and 60% Bloomberg Barclays U.S. Aggregate Bond Index.

Schwab Monthly Income Fund - Enhanced Payout

Schwab^® Monthly Income Fund – Enhanced Payout

Investment Objective

The fund seeks to provide current income and,

as a secondary investment objective, capital appreciation.

Fund Fees and Expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	Schwab Monthly Income Fund - Enhanced Payout Schwab Monthly Income Fund - Enhanced Payout USD ($)
Shareholder Fees (fees paid directly from your investment)	none

Annual Fund Operating Expenses (expenses that you pay each year as a % of the value of your investment)

Management fees	none
Distribution (12b-1) fees	none
Other expenses	0.11%
Acquired fund fees and expenses (AFFE)	0.46%	[1]

Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those 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 expense reduction. The expenses would be the same whether you stayed in the fund or sold your shares at the end of each period. Your actual costs may be higher or lower.

Expenses on a $10,000 Investment

Expense Example	1 Year	3 Years	5 Years	10 Years
Schwab Monthly Income Fund - Enhanced Payout | Schwab Monthly Income Fund - Enhanced Payout | USD ($)	47	148	258	579

Portfolio Turnover

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 50% of the average value of its portfolio.

Principal Investment Strategies

The fund seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds^® and Laudus Funds (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds.

The fund intends to invest in a combination of underlying funds; however, the fund may invest directly in equity and fixed income securities, cash and cash equivalents (including money market securities), exchange-traded funds (ETFs) and nonproprietary mutual funds.

The fund intends to allocate investments among various asset classes such as equity, fixed income and cash and cash equivalents (including money market funds). The fund has its own distinct asset allocation strategy that is designed to accommodate the fund’s targeted annual payout percentage while taking into account the fund’s specific risk tolerances and desired level of capital appreciation. The fund’s target asset allocation is not fixed, and the fund has the flexibility to move within the following asset allocation ranges (under normal market conditions) at the discretion of the investment adviser: 10%-40% equity; 50%-90% fixed income; and 0%-12% cash and cash equivalents (including money market funds). Market appreciation or depreciation may cause the fund to be temporarily outside these ranges.

The fund is designed to offer investors a targeted annual payout of 4-5%. The targeted annual payout for the fund is based on historic yield environments over a ten year period. The fund’s actual annual payout could be higher or lower than the targeted annual payout based on the interest rate environment and other market factors occurring during that year. The fund’s anticipated annual payout during a low interest rate environment is expected to be 1-4% and, during a high interest rate environment, is expected to be 4-7%. The fund intends to make twelve monthly distributions to shareholders on or about the 15^th calendar day of each month. The amounts distributed to shareholders are not fixed and may not be the same each month. Although it cannot be guaranteed by the fund, the fund does not expect to make distributions that will be treated as return of capital.

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.

Principal Risks

The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include:

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.

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. 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.

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.

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.

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.

• 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.

• 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.

• 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.

• 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.

• 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 improving economic conditions, among other things, may result in an increase in interest rates.  A sharp rise in interest rates could cause an underlying fund to lose value. 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 the fund's yield or share price. Below investment-grade bonds (junk bonds) involve greater risks than investment-grade securities.

• 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.

• 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 volatility, and could 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.

• Leverage Risk. Certain underlying fund transactions, such as derivatives, 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. The fund may invest in underlying money market funds that either seek to maintain a stable $1 net asset value ("stable share price money market funds") or that have a share price that fluctuates ("variable share price money market funds"). Although an underlying stable share price money market fund seeks to maintain a stable $1 net asset value, it is possible to lose money by investing in such a money market fund. Because the share price of an underlying variable share price money market fund will fluctuate, when the fund sells the shares it owns they may be worth more or less than what the fund originally paid for them. In addition, neither type of money market fund is designed to offer capital appreciation. Certain underlying money market funds may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if such fund's liquidity falls below required minimums.

• 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.

• ETF Risk. When an underlying 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.

• 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.

• 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.

• Mortgage-Backed and Mortgage Pass-Through Securities Risk. Certain of the mortgage-backed securities in which an underlying fund may invest are not backed by the full faith and credit of the U.S. government and there can be no assurance that the U.S. government would provide financial support where it was not obligated to do so. Mortgage-backed securities tend to increase in value less than other debt securities when interest rates decline, but are subject to similar or greater risk of decline in market value during periods of rising interest rates. Transactions in mortgage pass-through securities primarily occur through to be announced (TBA) transactions. Default by or bankruptcy of a counterparty to a TBA transaction would expose an underlying fund to possible losses.

• 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.

[1] Acquired fund fees and expenses (AFFE) are based on estimated amounts for the current fiscal period. AFFE reflect fees and expenses incurred indirectly by the fund through its investments in the underlying funds. The total annual fund operating expenses in the fee table may differ from the expense ratios in the fund’s “Financial Highlights” that include only the fund’s direct operating expenses and not AFFE.

[2] The investment adviser and its affiliates have agreed to limit the total annual fund operating expenses (excluding interest, taxes and certain non-routine expenses) of the fund to 0.00% for so long as the investment adviser serves as the adviser to the fund. This agreement may only be amended or terminated with the approval of the fund’s Board of Trustees. This agreement is limited to the fund’s direct operating expenses and does not apply to AFFE.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The fund seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds® and Laudus Funds (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds. The fund intends to invest in a combination of underlying funds; however, the fund may invest directly in equity and fixed income securities, cash and cash equivalents (including money market securities), exchange-traded funds (ETFs) and nonproprietary mutual funds. The fund intends to allocate investments among various asset classes such as equity, fixed income and cash and cash equivalents (including money market funds). The fund has its own distinct asset allocation strategy that is designed to accommodate the fund’s targeted annual payout percentage while taking into account the fund’s specific risk tolerances and desired level of capital appreciation. The fund’s target asset allocation is not fixed, and the fund has the flexibility to move within the following asset allocation ranges (under normal market conditions) at the discretion of the investment adviser: 10%-40% equity; 50%-90% fixed income; and 0%-12% cash and cash equivalents (including money market funds). Market appreciation or depreciation may cause the fund to be temporarily outside these ranges. The fund is designed to offer investors a targeted annual payout of 4-5%. The targeted annual payout for the fund is based on historic yield environments over a ten year period. The fund’s actual annual payout could be higher or lower than the targeted annual payout based on the interest rate environment and other market factors occurring during that year. The fund’s anticipated annual payout during a low interest rate environment is expected to be 1-4% and, during a high interest rate environment, is expected to be 4-7%. The fund intends to make twelve monthly distributions to shareholders on or about the 15th calendar day of each month. The amounts distributed to shareholders are not fixed and may not be the same each month. Although it cannot be guaranteed by the fund, the fund does not expect to make distributions that will be treated as return of capital. 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.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include: 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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 improving economic conditions, among other things, may result in an increase in interest rates.  A sharp rise in interest rates could cause an underlying fund to lose value. 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 the fund's yield or share price. Below investment-grade bonds (junk bonds) involve greater risks than investment-grade securities. 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. 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 volatility, and could 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. Leverage Risk. Certain underlying fund transactions, such as derivatives, 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. The fund may invest in underlying money market funds that either seek to maintain a stable $1 net asset value ("stable share price money market funds") or that have a share price that fluctuates ("variable share price money market funds"). Although an underlying stable share price money market fund seeks to maintain a stable $1 net asset value, it is possible to lose money by investing in such a money market fund. Because the share price of an underlying variable share price money market fund will fluctuate, when the fund sells the shares it owns they may be worth more or less than what the fund originally paid for them. In addition, neither type of money market fund is designed to offer capital appreciation. Certain underlying money market funds may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if such fund's liquidity falls below required minimums. 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. ETF Risk. When an underlying 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. 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. 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. Mortgage-Backed and Mortgage Pass-Through Securities Risk. Certain of the mortgage-backed securities in which an underlying fund may invest are not backed by the full faith and credit of the U.S. government and there can be no assurance that the U.S. government would provide financial support where it was not obligated to do so. Mortgage-backed securities tend to increase in value less than other debt securities when interest rates decline, but are subject to similar or greater risk of decline in market value during periods of rising interest rates. Transactions in mortgage pass-through securities primarily occur through to be announced (TBA) transactions. Default by or bankruptcy of a counterparty to a TBA transaction would expose an underlying fund to possible losses. 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. For more information on the risks of investing in the fund and the underlying funds, please see the “Fund Details” section in the prospectus.

Expense Example	1 Year	3 Years	5 Years	10 Years
Schwab Monthly Income Fund - Maximum Payout | Schwab Monthly Income Fund - Maximum Payout | USD ($)	35	109	191	431

Portfolio Turnover

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 63% of the average value of its portfolio.

Principal Investment Strategies

The fund seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds^® and Laudus Funds (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds.

The fund intends to invest in a combination of underlying funds; however, the fund may invest directly in equity and fixed income securities, cash and cash equivalents (including money market securities), exchange-traded funds (ETFs) and nonproprietary mutual funds.

The fund intends to allocate investments among various asset classes such as equity, fixed income and cash and cash equivalents (including money market funds). The fund has its own distinct asset allocation strategy that is designed to accommodate the fund’s targeted annual payout percentage while taking into account the fund’s specific risk tolerances and desired level of capital appreciation. The fund’s target asset allocation is not fixed, and the fund has the flexibility to move within the following asset allocation ranges (under normal market conditions) at the discretion of the investment adviser: 0%-25% equity; 60%-100% fixed income; and 0%-15% cash and cash equivalents (including money market funds). Market appreciation or depreciation may cause the fund to be temporarily outside these ranges.

The fund is designed to offer investors a targeted annual payout of 5-6%. The targeted annual payout for the fund is based on historic yield environments over a ten year period. The fund’s actual annual payout could be higher or lower than the targeted annual payout based on the interest rate environment and other market factors occurring during that year. The fund’s anticipated annual payout during a low interest rate environment is expected to be 1-5% and, during a high interest rate environment, is expected to be 5-8%. The fund intends to make twelve monthly distributions to shareholders on or about the 15^th calendar day of each month. The amounts distributed to shareholders are not fixed and may not be the same each month. Although it cannot be guaranteed by the fund, the fund does not expect to make distributions that will be treated as return of capital.

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.

Principal Risks

The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include:

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.

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. 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.

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.

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.

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.

• 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.

• 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.

• 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.

• 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.

• 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 improving economic conditions, among other things, may result in an increase in interest rates.  A sharp rise in interest rates could cause an underlying fund to lose value. 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 the fund's yield or share price. Below investment-grade bonds (junk bonds) involve greater risks than investment-grade securities.

• 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.

• 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 volatility, and could 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.

• Leverage Risk. Certain underlying fund transactions, such as derivatives, 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. The fund may invest in underlying money market funds that either seek to maintain a stable $1 net asset value ("stable share price money market funds") or that have a share price that fluctuates ("variable share price money market funds"). Although an underlying stable share price money market fund seeks to maintain a stable $1 net asset value, it is possible to lose money by investing in such a money market fund. Because the share price of an underlying variable share price money market fund will fluctuate, when the fund sells the shares it owns they may be worth more or less than what the fund originally paid for them. In addition, neither type of money market fund is designed to offer capital appreciation. Certain underlying money market funds may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if such fund's liquidity falls below required minimums.

• 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.

• ETF Risk. When an underlying 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.

• 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.

• 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.

• Mortgage-Backed and Mortgage Pass-Through Securities Risk. Certain of the mortgage-backed securities in which an underlying fund may invest are not backed by the full faith and credit of the U.S. government and there can be no assurance that the U.S. government would provide financial support where it was not obligated to do so. Mortgage-backed securities tend to increase in value less than other debt securities when interest rates decline, but are subject to similar or greater risk of decline in market value during periods of rising interest rates. Transactions in mortgage pass-through securities primarily occur through to be announced (TBA) transactions. Default by or bankruptcy of a counterparty to a TBA transaction would expose an underlying fund to possible losses.

• 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.

The after-tax figures reflect the highest individual federal income tax rates in effect during the period and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation. In addition, after-tax returns are not relevant if you hold your fund shares through a tax-deferred arrangement, such as a 401(k) plan, an individual retirement account (IRA) or other tax-advantaged account. In some cases, the return after taxes on distributions and sale of shares may exceed the fund's other returns due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

[1] Acquired fund fees and expenses (AFFE) are based on estimated amounts for the current fiscal period. AFFE reflect fees and expenses incurred indirectly by the fund through its investments in the underlying funds. The total annual fund operating expenses in the fee table may differ from the expense ratios in the fund’s “Financial Highlights” that include only the fund’s direct operating expenses and not AFFE.

[2] The investment adviser and its affiliates have agreed to limit the total annual fund operating expenses (excluding interest, taxes and certain non-routine expenses) of the fund to 0.00% for so long as the investment adviser serves as the adviser to the fund. This agreement may only be amended or terminated with the approval of the fund’s Board of Trustees. This agreement is limited to the fund’s direct operating expenses and does not apply to AFFE.

[1] The Maximum Payout Composite Index is a custom blended index developed by CSIM based on a comparable portfolio asset allocation. Effective April 1, 2013, the Maximum Payout Composite Index is composed of 10.50% S& P 500 Index, 4.37% MSCI EAFE (Net) Index, 2.63% FTSE EPRA/NAREIT Global Index (Net), 48.30% Bloomberg Barclays U.S. Aggregate Bond Index, 32.20% Bloomberg Barclays U.S. Intermediate Aggregate Bond Index, and 2.00% Bloomberg Barclays U.S. Treasury Bills: 1-3 Months. Prior to April 1, 2013, the Maximum Payout Composite Index was composed of 10% S&P 500 Index and 90% Bloomberg Barclays U.S. Aggregate Bond Index.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The fund seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds® and Laudus Funds (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds. The fund intends to invest in a combination of underlying funds; however, the fund may invest directly in equity and fixed income securities, cash and cash equivalents (including money market securities), exchange-traded funds (ETFs) and nonproprietary mutual funds. The fund intends to allocate investments among various asset classes such as equity, fixed income and cash and cash equivalents (including money market funds). The fund has its own distinct asset allocation strategy that is designed to accommodate the fund’s targeted annual payout percentage while taking into account the fund’s specific risk tolerances and desired level of capital appreciation. The fund’s target asset allocation is not fixed, and the fund has the flexibility to move within the following asset allocation ranges (under normal market conditions) at the discretion of the investment adviser: 0%-25% equity; 60%-100% fixed income; and 0%-15% cash and cash equivalents (including money market funds). Market appreciation or depreciation may cause the fund to be temporarily outside these ranges. The fund is designed to offer investors a targeted annual payout of 5-6%. The targeted annual payout for the fund is based on historic yield environments over a ten year period. The fund’s actual annual payout could be higher or lower than the targeted annual payout based on the interest rate environment and other market factors occurring during that year. The fund’s anticipated annual payout during a low interest rate environment is expected to be 1-5% and, during a high interest rate environment, is expected to be 5-8%. The fund intends to make twelve monthly distributions to shareholders on or about the 15th calendar day of each month. The amounts distributed to shareholders are not fixed and may not be the same each month. Although it cannot be guaranteed by the fund, the fund does not expect to make distributions that will be treated as return of capital. 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.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include: 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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 improving economic conditions, among other things, may result in an increase in interest rates.  A sharp rise in interest rates could cause an underlying fund to lose value. 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 the fund's yield or share price. Below investment-grade bonds (junk bonds) involve greater risks than investment-grade securities. 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. 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 volatility, and could 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. Leverage Risk. Certain underlying fund transactions, such as derivatives, 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. The fund may invest in underlying money market funds that either seek to maintain a stable $1 net asset value ("stable share price money market funds") or that have a share price that fluctuates ("variable share price money market funds"). Although an underlying stable share price money market fund seeks to maintain a stable $1 net asset value, it is possible to lose money by investing in such a money market fund. Because the share price of an underlying variable share price money market fund will fluctuate, when the fund sells the shares it owns they may be worth more or less than what the fund originally paid for them. In addition, neither type of money market fund is designed to offer capital appreciation. Certain underlying money market funds may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if such fund's liquidity falls below required minimums. 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. ETF Risk. When an underlying 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. 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. 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. Mortgage-Backed and Mortgage Pass-Through Securities Risk. Certain of the mortgage-backed securities in which an underlying fund may invest are not backed by the full faith and credit of the U.S. government and there can be no assurance that the U.S. government would provide financial support where it was not obligated to do so. Mortgage-backed securities tend to increase in value less than other debt securities when interest rates decline, but are subject to similar or greater risk of decline in market value during periods of rising interest rates. Transactions in mortgage pass-through securities primarily occur through to be announced (TBA) transactions. Default by or bankruptcy of a counterparty to a TBA transaction would expose an underlying fund to possible losses. 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. For more information on the risks of investing in the fund and the underlying funds, please see the “Fund Details” section in the prospectus.

[1] Acquired fund fees and expenses (AFFE) are based on estimated amounts for the current fiscal period. AFFE reflect fees and expenses incurred indirectly by the fund through its investments in the underlying funds. The total annual fund operating expenses in the fee table may differ from the expense ratios in the fund’s “Financial Highlights” that include only the fund’s direct operating expenses and not AFFE.

[2] The investment adviser and its affiliates have agreed to limit the total annual fund operating expenses (excluding interest, taxes and certain non-routine expenses) of the fund to 0.00% for so long as the investment adviser serves as the adviser to the fund. This agreement may only be amended or terminated with the approval of the fund’s Board of Trustees. This agreement is limited to the fund’s direct operating expenses and does not apply to AFFE.

[3] The Maximum Payout Composite Index is a custom blended index developed by CSIM based on a comparable portfolio asset allocation. Effective April 1, 2013, the Maximum Payout Composite Index is composed of 10.50% S& P 500 Index, 4.37% MSCI EAFE (Net) Index, 2.63% FTSE EPRA/NAREIT Global Index (Net), 48.30% Bloomberg Barclays U.S. Aggregate Bond Index, 32.20% Bloomberg Barclays U.S. Intermediate Aggregate Bond Index, and 2.00% Bloomberg Barclays U.S. Treasury Bills: 1-3 Months. Prior to April 1, 2013, the Maximum Payout Composite Index was composed of 10% S&P 500 Index and 90% Bloomberg Barclays U.S. Aggregate Bond Index.
