Dreyfus Moderate Allocation Fund (Prospectus Summary) | Dreyfus Moderate Allocation Fund

Fund Summary

Investment Objective

The fund seeks a balance of current income and capital appreciation.

Fees and Expenses

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

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

Annual Fund Operating Expenses		Dreyfus Moderate Allocation Fund
Management fees		none
Other expenses (including shareholder services fees)		0.63%
Underlying funds fees		0.76%
Total annual fund and underlying funds operating expenses	[1]	1.39%
Fee waiver and/or expense reimbursement		(0.34%)
Total annual fund and underlying funds operating expenses (after fee waiver and/or expense reimbursement)	[1]	1.05%

Example

The 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 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 one-year example and the first year of the three-, five-,
and ten-years examples are based on net operating expenses, which reflect the
expense waiver/reimbursement by The Dreyfus Corporation. Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Dreyfus Moderate Allocation Fund	107	407	728	1,639

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
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
28.82% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally allocates its net assets among other
mutual funds advised by The Dreyfus Corporation or its affiliates, referred
to as underlying funds, that invest in a wide range of equity and fixed-income
securities. The fund normally allocates 60% of its assets to the equity asset
class and 40% of its assets to the fixed-income asset class by investing in
underlying funds that invest primarily in equity and fixed-income securities,
respectively. The fund may invest in underlying funds that invest in U.S.
large-, mid- and small-cap equity securities, international equity securities,
emerging markets equity securities and global equity securities, which comprise
the equity asset category. The fund also may invest in underlying funds that
invest in U.S. and international fixed-income securities, which comprise the
fixed-income asset category.
  
Although an investor may achieve the same level of diversification by investing
directly in a variety of Dreyfus-managed funds, the fund provides investors with
a means to simplify their investment decisions by investing in a single
diversified portfolio. The fund is designed for investors with moderate-to-high
risk tolerances.

The underlying funds are selected by the Dreyfus Investment Committee based on
their investment objectives and management policies, portfolio holdings,
risk/reward profiles, historical performance, and other factors, including the
correlation and covariance among the underlying funds. The underlying funds in
which the fund may invest, as of the date of this Prospectus, are as follows:

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any
other government agency. It is not a complete investment program. The
fund's share price fluctuates, sometimes dramatically, which means you
could lose money.

An investment in the fund is subject to the following principal risks:

o Allocation risk. The ability of the fund to achieve its investment goal
depends, in part, on the ability of the Dreyfus Investment Committee to
allocate effectively the fund's assets among the underlying funds. There
can be no assurance that the actual allocations will be effective in
achieving the fund's investment goal. The underlying funds may not achieve
their investment objectives, and their performance may be lower than that
of the overall performance of the asset class the underlying funds were
selected to represent. The fund typically invests in a number of different
underlying funds; however, to the extent the fund invests a significant
portion of its assets in a single underlying fund, the fund will be more
sensitive to the risks associated with that underlying fund and any
investments in which that underlying fund concentrates.

o Conflicts of interest risk. The fund's investment adviser, The Dreyfus
Corporation, or its affiliates may serve as investment adviser to the underlying
funds. The interests of the fund on the one hand, and those of an underlying
fund on the other, will not always be the same. Therefore, conflicts may arise
as the investment adviser fulfills its fiduciary duty to the fund and the
underlying funds. In addition, the Dreyfus Investment Committee recommends asset
allocations among the underlying funds, each of which pays advisory fees at
different rates to The Dreyfus Corporation or its affiliates. These situations
are considered by the fund's board when it reviews the asset allocations for the
fund.
  
o Correlation risk. Although the prices of equity securities and fixed-income
securities often rise and fall at different times so that a fall in the price
of one may be offset by a rise in the price of the other, in down markets the
prices of these securities can also fall in tandem. Because the fund invests
in equity securities and fixed-income securities, it is subject to correlation
risk.

The fund is subject to the same principal risks as the underlying funds in which
it invests, which are summarized below. For more information regarding these and
other risks of the underlying funds, see the prospectus for the specific
underlying fund.

o Risks of stock investing. Stocks generally fluctuate more in value than bonds
and may decline significantly over short time periods. There is the chance that
stock prices overall will decline because stock markets tend to move in cycles,
with periods of rising prices and falling prices. The market value of a stock
may decline due to general weakness in the stock market or because of factors
that affect the company or its particular industry.

o Large cap stock risk. To the extent the fund invests in large capitalization
stocks, the fund may underperform funds that invest primarily in the stocks of
lower quality, smaller capitalization companies during periods when the stocks
of such companies are in favor.

o Small and midsize company risk. Small and midsize companies carry additional
risks because the operating histories of these companies tend to be more
limited, their earnings and revenues less predictable (and some companies may
be experiencing significant losses), and their share prices more volatile than
those of larger, more established companies. The shares of smaller companies
tend to trade less frequently than those of larger, more established companies,
which can adversely affect the pricing of these securities and the fund's
ability to sell these securities.

o Foreign investment risk. Special risks associated with investments in foreign
issuers include exposure to currency fluctuations, less liquidity, less
developed or less efficient trading markets, lack of comprehensive company
information, political and economic instability and differing auditing and legal
standards. Investments denominated in foreign currencies are subject to the risk
that such currencies will decline in value relative to the U.S. dollar and
affect the value of these investments held by the fund. These risks are
heightened for investments in emerging markets.

o Interest rate risk. Prices of bonds tend to move inversely with changes in
interest rates. Typically, a rise in rates will adversely affect bond prices
and, accordingly, the fund's share price. The longer the effective maturity and
duration of the fund's portfolio, the more the fund's share price is likely to
react to interest rates.

o Credit risk. Failure of an issuer to make timely interest or principal
payments, or a decline or perception of a decline in the credit quality of a
bond, can cause a bond's price to fall, potentially lowering the fund's share
price. The lower a bond's credit rating, the greater the chance - in the rating
agency's opinion - that the bond issuer will default or fail to meet its payment
obligations. High yield ("junk") bonds involve greater credit risk, including
the risk of default, than investment grade bonds, and are considered
predominantly speculative with respect to the issuer's ability to make principal
and interest payments. The prices of high yield bonds can fall dramatically in
response to bad news about the issuer or its industry, or the economy in
general.

o Market sector risk. The fund may significantly overweight or underweight
certain companies, industries or market sectors, which may cause the fund's
performance to be more or less sensitive to developments affecting those
companies, industries or sectors.

o Liquidity risk. When there is little or no active trading market for a
security, the fund may not be able to sell the security in a timely manner
at its perceived value, which could cause the fund's share price to fall.
Investments in foreign securities, particularly those of issuers located in
emerging markets, tend to have greater exposure to liquidity risk than domestic
securities.

Performance

The following bar chart and table provide some indication of the risks of
investing in the fund. The table compares the average annual total returns
of the fund's shares to those of a broad measure of market performance.
The fund's past performance (before and after taxes) is not necessarily an
indication of how the fund will perform in the future. More recent
performance information may be available at www.dreyfus.com.

The bar chart shows changes in the performance of the fund's shares from year
to year.

Year-by-Year Total Returns as of 12/31 each year (%)

Best Quarter
Q3, 2010: 8.89%
Worst Quarter

The fund's year-to-date total return as of 9/30/12 was 9.82%.

After-tax returns are calculated using the historical highest individual federal
marginal tax rates, and do not reflect the impact of state and local taxes.
Actual after-tax returns depend on the investor's tax situation and may differ
from those shown, and the after-tax returns shown are not relevant to investors
who hold their shares through tax-deferred arrangements such as 401(k) plans or

[1] The Dreyfus Corporation has contractually agreed, until January 1, 2014, to assume the expenses of the fund so that the total annual fund and underlying funds operating expenses (excluding taxes, interest expense, brokerage commissions, commitment fees on borrowings and extraordinary expenses) do not exceed 1.05%. On or after January 1, 2014, The Dreyfus Corporation may terminate this expense waiver at any time.

Fund Summary

Investment Objective

The fund seeks current income with some consideration for capital appreciation.

Fees and Expenses

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

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

Annual Fund Operating Expenses		Dreyfus Conservative Allocation Fund

invest $10,000 in the fund for the time periods indicated and then redeem all
of your shares at the end of those 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 one-year example and the first year of the three-, five-,

Dreyfus Conservative Allocation Fund	95	414	756	1,721

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
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
25.89% of the average value of its portfolio.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 25.89% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The 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 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 one-year example and the first year of the three-, five-, and ten- years examples are based on net operating expenses, which reflect the expense waiver/reimbursement by The Dreyfus Corporation. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	To pursue its goal, the fund normally allocates its net assets among other mutual funds advised by The Dreyfus Corporation or its affiliates, referred to as underlying funds, that invest in a wide range of equity and fixed-income securities. The fund normally allocates 60% of its assets to the fixed-income asset class and 40% of its assets to the equity asset class by investing in underlying funds that invest primarily in fixed-income and equity securities, respectively. The fund may invest in underlying funds that invest in U.S. and international fixed-income securities, which comprise the fixed-income asset category. The fund also may invest in underlying funds that invest in U.S. large-, mid- and small-cap equity securities, international equity securities, emerging markets equity securities and global equity securities, which comprise the equity asset category. Although an investor may achieve the same level of diversification by investing directly in a variety of Dreyfus-managed funds, the fund provides investors with a means to simplify their investment decisions by investing in a single diversified portfolio. The fund is designed for investors with lower risk tolerances. The underlying funds are selected by the Dreyfus Investment Committee based on their investment objectives and management policies, portfolio holdings, risk/reward profiles, historical performance, and other factors, including the correlation and covariance among the underlying funds. The underlying funds in which the fund may invest, as of the date of this Prospectus, are as follows: Equity Investments                                                                U.S. Large-Cap                              International                         Dreyfus Appreciation Fund, Inc.             Dreyfus/Newton International Equity                                               Fund                                  Dreyfus Research Growth Fund                Dreyfus International Equity Fund     Dreyfus Strategic Value Fund                Dreyfus International Value Fund      Dreyfus Disciplined Stock Fund              International Stock Fund              Dreyfus U.S. Equity Fund                    Dreyfus International Stock Index                                                 Fund                                  Dreyfus BASIC S&P 500 Stock Index Fund      Emerging Markets                      U.S. Mid-/Small-Cap                         Dreyfus Emerging Markets Fund         Dreyfus Select Managers Small Cap Value     Global                                Fund                                         Dreyfus Opportunistic Midcap Value Fund     Dreyfus Global Absolute Return Fund   Dreyfus MidCap Core Fund                    Dreyfus Global Real Estate Securities                                             Fund                                  Dreyfus/The Boston Company Small/Mid Cap                                          Growth Fund                                  Dreyfus Smallcap Stock Index Fund                                                 Dreyfus Midcap Index Fund, Inc.                                                                                                                                     Fixed-Income Investments                                                          U.S. Fixed-Income                           International Fixed-Income            Dreyfus Total Return Advantage Fund         Dreyfus Emerging Markets Debt Local                                               Currency Fund                         Dreyfus Short-Intermediate Government Fund  Dreyfus International Bond Fund       Dreyfus GNMA Fund                                                                 Dreyfus Opportunistic Fixed Income Fund                                           Dreyfus High Yield Fund                                                           Dreyfus Bond Market Index Fund                                                    Dreyfus Inflation Adjusted Securities Fund                                        Dreyfus U.S. Treasury Intermediate Term                                           Fund                                         Dreyfus U.S. Treasury Long Term Fund
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. An investment in the fund is subject to the following principal risks: o Allocation risk. The ability of the fund to achieve its investment goal depends, in part, on the ability of the Dreyfus Investment Committee to allocate effectively the fund's assets among the underlying funds. There can be no assurance that the actual allocations will be effective in achieving the fund's investment goal. The underlying funds may not achieve their investment objectives, and their performance may be lower than that of the overall performance of the asset class the underlying funds were selected to represent. The fund typically invests in a number of different underlying funds; however, to the extent the fund invests a significant portion of its assets in a single underlying fund, the fund will be more sensitive to the risks associated with that underlying fund and any investments in which that underlying fund concentrates. o Conflicts of interest risk. The fund's investment adviser, The Dreyfus Corporation, or its affiliates may serve as investment adviser to the underlying funds. The interests of the fund on the one hand, and those of an underlying fund on the other, will not always be the same. Therefore, conflicts may arise as the investment adviser fulfills its fiduciary duty to the fund and the underlying funds. In addition, the Dreyfus Investment Committee recommends asset allocations among the underlying funds, each of which pays advisory fees at different rates to The Dreyfus Corporation or its affiliates. These situations are considered by the fund's board when it reviews the asset allocations for the fund. o Correlation risk. Although the prices of equity securities and fixed-income securities often rise and fall at different times so that a fall in the price of one may be offset by a rise in the price of the other, in down markets the prices of these securities can also fall in tandem. Because the fund invests in equity securities and fixed-income securities, it is subject to correlation risk. The fund is subject to the same principal risks as the underlying funds in which it invests, which are summarized below. For more information regarding these and other risks of the underlying funds, see the prospectus for the specific underlying fund. o Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general weakness in the stock market or because of factors that affect the company or its particular industry. o Large cap stock risk. To the extent the fund invests in large capitalization stocks, the fund may underperform funds that invest primarily in the stocks of lower quality, smaller capitalization companies during periods when the stocks of such companies are in favor. o Small and midsize company risk. Small and midsize companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies. The shares of smaller companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the fund's ability to sell these securities. o Foreign investment risk. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards. Investments denominated in foreign currencies are subject to the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held by the fund. These risks are heightened for investments in emerging markets. o Interest rate risk. Prices of bonds tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect bond prices and, accordingly, the fund's share price. The longer the effective maturity and duration of the fund's portfolio, the more the fund's share price is likely to react to interest rates. o Credit risk. Failure of an issuer to make timely interest or principal payments, or a decline or perception of a decline in the credit quality of a bond, can cause a bond's price to fall, potentially lowering the fund's share price. The lower a bond's credit rating, the greater the chance - in the rating agency's opinion - that the bond issuer will default or fail to meet its payment obligations. High yield ("junk") bonds involve greater credit risk, including the risk of default, than investment grade bonds, and are considered predominantly speculative with respect to the issuer's ability to make principal and interest payments. The prices of high yield bonds can fall dramatically in response to bad news about the issuer or its industry, or the economy in general. o Market sector risk. The fund may significantly overweight or underweight certain companies, industries or market sectors, which may cause the fund's performance to be more or less sensitive to developments affecting those companies, industries or sectors. o Liquidity risk. When there is little or no active trading market for a security, the fund may not be able to sell the security in a timely manner at its perceived value, which could cause the fund's share price to fall. Investments in foreign securities, particularly those of issuers located in emerging markets, tend to have greater exposure to liquidity risk than domestic securities.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	To pursue its goal, the fund normally allocates its net assets among other mutual funds advised by The Dreyfus Corporation or its affiliates, referred to as underlying funds, that invest in a wide range of equity and fixed-income securities. The fund normally allocates 80% of its assets to the equity asset class and 20% of its assets to the fixed-income asset class by investing in underlying funds that invest primarily in equity and fixed-income securities, respectively. The fund may invest in underlying funds that invest in U.S. large-, mid- and small-cap equity securities, international equity securities, emerging markets equity securities and global equity securities, which comprise the equity asset category. The fund also may invest in underlying funds that invest in U.S. and international fixed-income securities, which comprise the fixed-income asset category.    Although an investor may achieve the same level of diversification by investing directly in a variety of Dreyfus-managed funds, the fund provides investors with a means to simplify their investment decisions by investing in a single diversified portfolio. The fund is designed for investors with high risk tolerances.

Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. An investment in the fund is subject to the following principal risks: o Allocation risk. The ability of the fund to achieve its investment goal depends, in part, on the ability of the Dreyfus Investment Committee to allocate effectively the fund's assets among the underlying funds. There can be no assurance that the actual allocations will be effective in achieving the fund's investment goal. The underlying funds may not achieve their investment objectives, and their performance may be lower than that of the overall performance of the asset class the underlying funds were selected to represent. The fund typically invests in a number of different underlying funds; however, to the extent the fund invests a significant portion of its assets in a single underlying fund, the fund will be more sensitive to the risks associated with that underlying fund and any investments in which that underlying fund concentrates. o Conflicts of interest risk. The fund's investment adviser, The Dreyfus Corporation, or its affiliates may serve as investment adviser to the underlying funds. The interests of the fund on the one hand, and those of an underlying fund on the other, will not always be the same. Therefore, conflicts may arise as the investment adviser fulfills its fiduciary duty to the fund and the underlying  funds. In addition, the Dreyfus Investment Committee recommends asset allocations among the underlying funds, each of which pays advisory fees at different rates to The Dreyfus Corporation or its affiliates. These situations are considered by the fund's board when it reviews the asset allocations for the fund. o Correlation risk. Although the prices of equity securities and fixed-income securities often rise and fall at different times so that a fall in the price of one may be offset by a rise in the price of the other, in down markets the prices of these securities can also fall in tandem. Because the fund invests in equity securities and fixed-income securities, it is subject to correlation risk. The fund is subject to the same principal risks as the underlying funds in which it invests, which are summarized below. For more information regarding these risks and other risks of the underlying funds, see the prospectus for the specific underlying fund. o Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general weakness in the stock market or because of factors that affect the company or its particular industry. o Large cap stock risk. To the extent the fund invests in large capitalization stocks, the fund may underperform funds that invest primarily in the stocks of lower quality, smaller capitalization companies during periods when the stocks of such companies are in favor. o Small and midsize company risk. Small and midsize companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies. The shares of smaller companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the fund's ability to sell these securities. o Foreign investment risk. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards. Investments denominated in foreign currencies are subject to the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held by the fund. These risks are heightened for investments in emerging markets. o Interest rate risk. Prices of bonds tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect bond prices and, accordingly, the fund's share price. The longer the effective maturity and duration of the fund's portfolio, the more the fund's share price is likely to react to interest rates. o Credit risk. Failure of an issuer to make timely interest or principal payments, or a decline or perception of a decline in the credit quality of a bond, can cause a bond's price to fall, potentially lowering the fund's share price. The lower a bond's credit rating, the greater the chance - in the rating agency's opinion - that the bond issuer will default or fail to meet its payment obligations. High yield ("junk") bonds involve greater credit risk, including the risk of default, than investment grade bonds, and are considered predominantly speculative with respect to the issuer's ability to make principal and interest payments. The prices of high yield bonds can fall dramatically in response to bad news about the issuer or its industry, or the economy in general. o Market sector risk. The fund may significantly overweight or underweight certain companies, industries or market sectors, which may cause the fund's performance to be more or less sensitive to developments affecting those companies, industries or sectors. o Liquidity risk. When there is little or no active trading market for a security, the fund may not be able to sell the security in a timely manner at its perceived value, which could cause the fund's share price to fall.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	To pursue its goal, the fund normally allocates its net assets among other mutual funds advised by The Dreyfus Corporation or its affiliates, referred to as underlying funds, that invest in a wide range of equity and fixed-income securities. The fund normally allocates 60% of its assets to the equity asset class and 40% of its assets to the fixed-income asset class by investing in underlying funds that invest primarily in equity and fixed-income securities, respectively. The fund may invest in underlying funds that invest in U.S. large-, mid- and small-cap equity securities, international equity securities, emerging markets equity securities and global equity securities, which comprise the equity asset category. The fund also may invest in underlying funds that invest in U.S. and international fixed-income securities, which comprise the fixed-income asset category.    Although an investor may achieve the same level of diversification by investing directly in a variety of Dreyfus-managed funds, the fund provides investors with a means to simplify their investment decisions by investing in a single diversified portfolio. The fund is designed for investors with moderate-to-high risk tolerances. The underlying funds are selected by the Dreyfus Investment Committee based on their investment objectives and management policies, portfolio holdings, risk/reward profiles, historical performance, and other factors, including the correlation and covariance among the underlying funds. The underlying funds in which the fund may invest, as of the date of this Prospectus, are as follows: Equity Investments                                                                U.S. Large-Cap                              International                         Dreyfus Appreciation Fund, Inc.             Dreyfus/Newton International Equity                                               Fund                                  Dreyfus Research Growth Fund                Dreyfus International Equity Fund     Dreyfus Strategic Value Fund                Dreyfus International Value Fund      Dreyfus Disciplined Stock Fund              International Stock Fund              Dreyfus U.S. Equity Fund                    Dreyfus International Stock Index                                                 Fund                                  Dreyfus BASIC S&P 500 Stock Index Fund      Emerging Markets                      U.S. Mid-/Small-Cap                         Dreyfus Emerging Markets Fund         Dreyfus Select Managers Small Cap Value     Global                                Fund                                         Dreyfus Opportunistic Midcap Value Fund     Dreyfus Global Absolute Return Fund   Dreyfus MidCap Core Fund                    Dreyfus Global Real Estate Securities                                             Fund                                  Dreyfus/The Boston Company Small/Mid Cap                                          Growth Fund                                  Dreyfus Smallcap Stock Index Fund                                                 Dreyfus Midcap Index Fund, Inc.                                                                                                                                     Fixed-Income Investments                                                          U.S. Fixed-Income                           International Fixed-Income            Dreyfus Total Return Advantage Fund         Dreyfus Emerging Markets Debt Local                                               Currency Fund                         Dreyfus Short-Intermediate Government Fund  Dreyfus International Bond Fund       Dreyfus GNMA Fund                                                                 Dreyfus Opportunistic Fixed Income Fund                                           Dreyfus High Yield Fund                                                           Dreyfus Bond Market Index Fund                                                    Dreyfus Inflation Adjusted Securities Fund                                        Dreyfus U.S. Treasury Intermediate Term                                           Fund                                         Dreyfus U.S. Treasury Long Term Fund
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. An investment in the fund is subject to the following principal risks: o Allocation risk. The ability of the fund to achieve its investment goal depends, in part, on the ability of the Dreyfus Investment Committee to allocate effectively the fund's assets among the underlying funds. There can be no assurance that the actual allocations will be effective in achieving the fund's investment goal. The underlying funds may not achieve their investment objectives, and their performance may be lower than that of the overall performance of the asset class the underlying funds were selected to represent. The fund typically invests in a number of different underlying funds; however, to the extent the fund invests a significant portion of its assets in a single underlying fund, the fund will be more sensitive to the risks associated with that underlying fund and any investments in which that underlying fund concentrates. o Conflicts of interest risk. The fund's investment adviser, The Dreyfus Corporation, or its affiliates may serve as investment adviser to the underlying funds. The interests of the fund on the one hand, and those of an underlying fund on the other, will not always be the same. Therefore, conflicts may arise as the investment adviser fulfills its fiduciary duty to the fund and the underlying funds. In addition, the Dreyfus Investment Committee recommends asset allocations among the underlying funds, each of which pays advisory fees at different rates to The Dreyfus Corporation or its affiliates. These situations are considered by the fund's board when it reviews the asset allocations for the fund.    o Correlation risk. Although the prices of equity securities and fixed-income securities often rise and fall at different times so that a fall in the price of one may be offset by a rise in the price of the other, in down markets the prices of these securities can also fall in tandem. Because the fund invests in equity securities and fixed-income securities, it is subject to correlation risk. The fund is subject to the same principal risks as the underlying funds in which it invests, which are summarized below. For more information regarding these and other risks of the underlying funds, see the prospectus for the specific underlying fund. o Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general weakness in the stock market or because of factors that affect the company or its particular industry. o Large cap stock risk. To the extent the fund invests in large capitalization stocks, the fund may underperform funds that invest primarily in the stocks of lower quality, smaller capitalization companies during periods when the stocks of such companies are in favor. o Small and midsize company risk. Small and midsize companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies. The shares of smaller companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the fund's ability to sell these securities. o Foreign investment risk. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards. Investments denominated in foreign currencies are subject to the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held by the fund. These risks are heightened for investments in emerging markets. o Interest rate risk. Prices of bonds tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect bond prices and, accordingly, the fund's share price. The longer the effective maturity and duration of the fund's portfolio, the more the fund's share price is likely to react to interest rates. o Credit risk. Failure of an issuer to make timely interest or principal payments, or a decline or perception of a decline in the credit quality of a bond, can cause a bond's price to fall, potentially lowering the fund's share price. The lower a bond's credit rating, the greater the chance - in the rating agency's opinion - that the bond issuer will default or fail to meet its payment obligations. High yield ("junk") bonds involve greater credit risk, including the risk of default, than investment grade bonds, and are considered predominantly speculative with respect to the issuer's ability to make principal and interest payments. The prices of high yield bonds can fall dramatically in response to bad news about the issuer or its industry, or the economy in general. o Market sector risk. The fund may significantly overweight or underweight certain companies, industries or market sectors, which may cause the fund's performance to be more or less sensitive to developments affecting those companies, industries or sectors. o Liquidity risk. When there is little or no active trading market for a security, the fund may not be able to sell the security in a timely manner at its perceived value, which could cause the fund's share price to fall. Investments in foreign securities, particularly those of issuers located in emerging markets, tend to have greater exposure to liquidity risk than domestic securities.

Dreyfus Growth Allocation Fund (Prospectus Summary) | Dreyfus Growth Allocation Fund

Fund Summary

Investment Objective

The fund seeks long-term capital appreciation with some consideration for
current income.

Fees and Expenses

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

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

Annual Fund Operating Expenses		Dreyfus Growth Allocation Fund
Management fees		none
Other expenses (including shareholder services fees)		1.01%
Underlying funds fees		0.88%
Total annual fund and underlying funds operating expenses	[1]	1.89%
Fee waiver and/or expense reimbursement		(0.72%)
Total annual fund and underlying funds operating expenses (after fee waiver and/or expense reimbursement)	[1]	1.17%

Example

The 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 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 one-year example and the first year of the three-, five-,
and ten-years examples are based on net operating expenses, which reflect the
expense waiver/reimbursement by The Dreyfus Corporation. Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Dreyfus Growth Allocation Fund	119	524	954	2,153

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
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
30.83% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally allocates its net assets among other
mutual funds advised by The Dreyfus Corporation or its affiliates, referred to
as underlying funds, that invest in a wide range of equity and fixed-income
securities. The fund normally allocates 80% of its assets to the equity asset
class and 20% of its assets to the fixed-income asset class by investing in
underlying funds that invest primarily in equity and fixed-income securities,
respectively. The fund may invest in underlying funds that invest in U.S.
large-, mid- and small-cap equity securities, international equity securities,
emerging markets equity securities and global equity securities, which comprise
the equity asset category. The fund also may invest in underlying funds that
invest in U.S. and international fixed-income securities, which comprise the
fixed-income asset category.
  
Although an investor may achieve the same level of diversification by investing
directly in a variety of Dreyfus-managed funds, the fund provides investors with
a means to simplify their investment decisions by investing in a single
diversified portfolio. The fund is designed for investors with high risk
tolerances.

The underlying funds are selected by the Dreyfus Investment Committee based on
their investment objectives and management policies, portfolio holdings,
risk/reward profiles, historical performance, and other factors, including the
correlation and covariance among the underlying funds. The underlying funds in
which the fund may invest, as of the date of this Prospectus, are as follows:

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any
other government agency. It is not a complete investment program. The
fund's share price fluctuates, sometimes dramatically, which means you
could lose money.

An investment in the fund is subject to the following principal risks:

o Allocation risk. The ability of the fund to achieve its investment goal
depends, in part, on the ability of the Dreyfus Investment Committee to
allocate effectively the fund's assets among the underlying funds. There
can be no assurance that the actual allocations will be effective in
achieving the fund's investment goal. The underlying funds may not achieve
their investment objectives, and their performance may be lower than that
of the overall performance of the asset class the underlying funds were
selected to represent. The fund typically invests in a number of different
underlying funds; however, to the extent the fund invests a significant
portion of its assets in a single underlying fund, the fund will be more
sensitive to the risks associated with that underlying fund and any
investments in which that underlying fund concentrates.

o Conflicts of interest risk. The fund's investment adviser, The Dreyfus
Corporation, or its affiliates may serve as investment adviser to the underlying
funds. The interests of the fund on the one hand, and those of an underlying
fund on the other, will not always be the same. Therefore, conflicts may arise
as the investment adviser fulfills its fiduciary duty to the fund and the
underlying  funds. In addition, the Dreyfus Investment Committee recommends
asset allocations among the underlying funds, each of which pays advisory fees
at different rates to The Dreyfus Corporation or its affiliates. These situations
are considered by the fund's board when it reviews the asset allocations for
the fund.

o Correlation risk. Although the prices of equity securities and fixed-income
securities often rise and fall at different times so that a fall in the price
of one may be offset by a rise in the price of the other, in down markets the
prices of these securities can also fall in tandem. Because the fund invests
in equity securities and fixed-income securities, it is subject to correlation
risk.

The fund is subject to the same principal risks as the underlying funds in which
it invests, which are summarized below. For more information regarding these
risks and other risks of the underlying funds, see the prospectus for the
specific underlying fund.

o Risks of stock investing. Stocks generally fluctuate more in value than bonds
and may decline significantly over short time periods. There is the chance that
stock prices overall will decline because stock markets tend to move in cycles,
with periods of rising prices and falling prices. The market value of a stock
may decline due to general weakness in the stock market or because of factors
that affect the company or its particular industry.

o Large cap stock risk. To the extent the fund invests in large capitalization
stocks, the fund may underperform funds that invest primarily in the stocks of
lower quality, smaller capitalization companies during periods when the stocks
of such companies are in favor.

o Small and midsize company risk. Small and midsize companies carry additional
risks because the operating histories of these companies tend to be more
limited, their earnings and revenues less predictable (and some companies may
be experiencing significant losses), and their share prices more volatile than
those of larger, more established companies. The shares of smaller companies
tend to trade less frequently than those of larger, more established companies,
which can adversely affect the pricing of these securities and the fund's
ability to sell these securities.

o Foreign investment risk. Special risks associated with investments in foreign
issuers include exposure to currency fluctuations, less liquidity, less developed
or less efficient trading markets, lack of comprehensive company information,
political and economic instability and differing auditing and legal standards.
Investments denominated in foreign currencies are subject to the risk that such
currencies will decline in value relative to the U.S. dollar and affect the value
of these investments held by the fund. These risks are heightened for investments
in emerging markets.

o Interest rate risk. Prices of bonds tend to move inversely with changes in
interest rates. Typically, a rise in rates will adversely affect bond prices
and, accordingly, the fund's share price. The longer the effective maturity and
duration of the fund's portfolio, the more the fund's share price is likely to
react to interest rates.

o Credit risk. Failure of an issuer to make timely interest or principal
payments, or a decline or perception of a decline in the credit quality of
a bond, can cause a bond's price to fall, potentially lowering the fund's
share price. The lower a bond's credit rating, the greater the chance - in
the rating agency's opinion - that the bond issuer will default or fail to
meet its payment obligations. High yield ("junk") bonds involve greater
credit risk, including the risk of default, than investment grade bonds, and
are considered predominantly speculative with respect to the issuer's ability
to make principal and interest payments. The prices of high yield bonds can
fall dramatically in response to bad news about the issuer or its industry,
or the economy in general.

o Market sector risk. The fund may significantly overweight or underweight
certain companies, industries or market sectors, which may cause the fund's
performance to be more or less sensitive to developments affecting those
companies, industries or sectors.

o Liquidity risk. When there is little or no active trading market for a
security, the fund may not be able to sell the security in a timely manner
at its perceived value, which could cause the fund's share price to fall.
Investments in foreign securities, particularly those of issuers located in
emerging markets, tend to have greater exposure to liquidity risk than domestic
securities.

Performance

The following bar chart and table provide some indication of the risks of
investing in the fund. The table compares the average annual total returns
of the fund's shares to those of a broad measure of market performance.
The fund's past performance (before and after taxes) is not necessarily
an indication of how the fund will perform in the future. More recent
performance information may be available at www.dreyfus.com.

The bar chart shows changes in the performance of the fund's shares from year
to year.
