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 rate 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 32% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund is a “fund of funds,” and invests its assets in other underlying mutual funds advised by Invesco Advisers, Inc. (Invesco or the Adviser) and exchange-traded funds (ETFs) and other pooled investment vehicles advised by Invesco Capital Management LLC (Invesco Capital) or mutual funds, ETFs and other pooled investment vehicles advised by unaffiliated advisers (the underlying funds). Invesco and Invesco Capital are affiliates of each other as they are both indirect wholly-owned subsidiaries of Invesco Ltd. The Fund’s target allocation is to invest approximately 70%-85% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 5%-30% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 5%-20% of its total assets in alternative asset classes including underlying funds that invest primarily in commodities and other derivatives. Approximately 20%-35% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. The Fund may also allocate up to 100% of its assets to affiliated or unaffiliated ETFs. The Adviser uses a three-step process to create the Fund’s portfolio including: (1) a strategic asset allocation by the Adviser among broad asset classes; (2) the actual selection by the Adviser of underlying funds to represent the broad asset classes and the determination by the Adviser of target weightings in these underlying funds; in the case where there are multiple funds in a broad asset class, the Adviser attempts to balance the amount of active risk contributed by each underlying fund in order to determine the allocation; and (3) the ongoing monitoring of the Fund’s asset class allocations, underlying funds and target weightings in the underlying funds. Based on the portfolio managers’ research, the strategic allocations of the portfolios are broadly diversified to gain exposure to areas of the market that the portfolio managers believe may perform well over a full market cycle, including periods of adverse economic environments such as recessions and inflationary growth. The portfolio managers gain exposure to the desired asset class by selecting the most representative funds. The Adviser rebalances the Fund’s investments in the underlying funds on an annual basis to keep them at their target weightings. Although the Adviser has the ability to rebalance on a more frequent basis if it believes it is appropriate to do so, the Fund’s asset class weightings may not match the above percentage weightings during a quarter due to market fluctuations, cash flows and other factors. The Adviser may change the Fund’s asset class allocations, the underlying funds or the target weightings in the underlying funds without notice to, or approval by, shareholders.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. Because the Fund is a fund of funds, the Fund is subject to the risks associated with the underlying funds in which it invests. The principal risks of investing in the underlying funds, and therefore the Fund, are: Allocation Risk. The Fund’s investment performance depends, in part, on how its assets are allocated among the underlying funds or asset classes. The Adviser’s evaluations and assumptions regarding the asset classes or the underlying funds in which the Fund invests may be incorrect, causing the Fund to be invested (or not invested) in one or more asset classes or underlying funds at an inopportune time, which could negatively affect the Fund’s performance. Authorized Participant Concentration Risk. Only an authorized participant (AP) may engage in creation or redemption transactions directly with an underlying ETF. An underlying ETF has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the shares of an underlying ETF. This risk may be heightened to the extent that securities held by an underlying ETF are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to an underlying ETF and no other AP is able to step forward to create or redeem creation units for an underlying ETF, this may result in a significantly diminished trading market for shares of an underlying ETF, and the shares of an underlying ETF may be more likely to trade at a premium or discount to NAV and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. Commodities Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of an underlying fund from certain commodity-linked derivatives was treated as non-qualifying income, an underlying fund might fail to qualify as a regulated investment company and be subject to federal income tax at the fund level. As a result of an announcement by the Internal Revenue Service (IRS), an underlying fund intends to invest in commodity-linked notes: (a) directly, relying on an opinion of counsel confirming that income from such investments should be qualifying income because such commodity-linked notes constitute securities under section 2(a)(36) of the Investment Company Act of 1940, as amended (1940 Act), or (b) indirectly through a wholly-owned foreign subsidiary. Should the IRS issue further guidance, or Congress enact legislation, that adversely affects the tax treatment of an underlying fund’s use of commodity-linked notes or a wholly-owned foreign subsidiary (which guidance might be applied to the underlying fund retroactively), it could, among other consequences, limit the underlying fund’s ability to pursue its investment strategy. Commodity-Linked Notes Risk. In addition to risks associated with the underlying commodities, investments in commodity-linked notes may be subject to additional risks, such as non-payment of interest and loss of principal, counterparty risk, lack of a secondary market and risk of greater volatility than traditional equity and debt securities. The value of the commodity-linked notes an underlying fund buys may fluctuate significantly because the values of the underlying investments to which they are linked are themselves volatile. Additionally, certain commodity-linked notes employ “economic” leverage by requiring payment by the issuer of an amount that is a multiple of the price increase or decrease of the underlying commodity, commodity index, or other economic variable. Such economic leverage will increase the volatility of the value of these commodity-linked notes and an underlying fund to the extent it invests in such notes. Commodity Risk. An underlying fund may have investment exposure to the commodities markets and/or a particular sector of the commodities markets, which may subject an underlying fund to greater volatility than investments in traditional securities, such as stocks and bonds. Volatility in the commodities markets may be caused by changes in overall market movements, domestic and foreign political and economic events and policies, war, acts of terrorism, changes in domestic or foreign interest rates and/or investor expectations concerning interest rates, domestic and foreign inflation rates, investment and trading activities of mutual funds, hedge funds and commodities funds, and factors such as drought, floods, weather, livestock disease, embargoes, tariffs and other regulatory developments, or supply and demand disruptions. Because an underlying fund’s performance may be linked to the performance of volatile commodities, investors should be willing to assume the risks of potentially significant fluctuations in the value of an underlying fund’s shares. Debt Securities Risk. The prices of debt securities held by an underlying fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause an underlying fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce an underlying fund’s distributable income because interest payments on floating rate debt instruments held by an underlying fund will decline. An underlying fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. An underlying fund’s adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event. Depositary Receipts Risk. Investing in depositary receipts involves the same risks as direct investments in foreign securities. In addition, the underlying issuers of certain depositary receipts are under no obligation to distribute shareholder communications or pass through any voting rights with respect to the deposited securities to the holders of such receipts. An underlying fund may therefore receive less timely information or have less control than if it invested directly in the foreign issuer. Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that the counterparty to the derivative contract will default on its obligation to pay an underlying fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in an underlying fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the underlying fund’s returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the underlying fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the underlying fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the underlying fund’s ability to use certain derivatives or their cost. Derivatives strategies may not always be successful. For example, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions. Emerging Markets Securities Risk. Emerging markets (also referred to as developing markets) are generally subject to greater market volatility, political, social and economic instability, uncertain trading markets and more governmental limitations on foreign investment than more developed markets. In addition, companies operating in emerging markets may be subject to lower trading volume and greater price fluctuations than companies in more developed markets. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, and lack of timely information. Exchange-Traded Fund Industry Concentration Risk. In following its methodology, an underlying exchange-traded fund’s underlying index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or industry group. To the extent that an underlying fund’s underlying index concentrates in the securities of issuers in a particular industry or industry group, an underlying fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, an underlying fund faces more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which an underlying fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups, or the market as a whole. Exchange-Traded Funds Risk. In addition to the risks associated with the underlying assets held by the exchange-traded fund, investments in exchange-traded funds are subject to the following additional risks: (1) an exchange-traded fund’s shares may trade above or below its net asset value; (2) an active trading market for the exchange-traded fund’s shares may not develop or be maintained; (3) trading an exchange-traded fund’s shares may be halted by the listing exchange; (4) a passively-managed exchange-traded fund may not track the performance of the reference asset; and (5) a passively-managed exchange-traded fund may hold troubled securities. Investment in exchange-traded funds may involve duplication of management fees and certain other expenses, as the Fund or an underlying fund indirectly bears its proportionate share of any expenses paid by the exchange-traded funds in which it invests. Further, certain exchange-traded funds in which the Fund or an underlying fund may invest are leveraged, which may result in economic leverage, permitting the Fund or an underlying fund to gain exposure that is greater than would be the case in an unlevered instrument, and potentially resulting in greater volatility. Foreign Currency Tax Risk. If the U.S. Treasury Department were to exercise its authority to issue regulations that exclude from the definition of “qualifying income” foreign currency gains not directly related to an underlying fund’s business of investing in securities, the underlying fund may be unable to qualify as a regulated investment company for one or more years. In this event, the underlying fund’s Board of Trustees may authorize a significant change in investment strategy or other action. Foreign Securities Risk. An underlying fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which an underlying fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls. Unless an underlying fund has hedged its foreign securities risk, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which an underlying fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful. Fund of Funds Risk. The Fund’s performance depends on that of the underlying funds in which it invests. Accordingly, the risks associated with an investment in the Fund include the risks associated with investments in the underlying funds. The Fund will indirectly pay a proportional share of the fees and expenses of the underlying funds in which it invests. There are risks that the Fund will vary from its target weightings (if any) in the underlying funds, that the underlying funds will not achieve their investment objectives, that the underlying funds’ performance may be lower than their represented asset classes, and that the Fund may withdraw its investments in an underlying fund at a disadvantageous time. Geographic Focus Risk. An underlying fund may from time to time invest a substantial amount of its assets in securities of issuers located in a single country or a limited number of countries. Adverse economic, political or social conditions in those countries may therefore have a significant negative impact on an underlying fund’s investment performance. Growth Investing Risk. Growth stocks tend to be more expensive relative to the issuing company’s earnings or assets compared with other types of stock. As a result, they tend to be more sensitive to changes in, or investors’ expectations of, the issuing company’s earnings and can be more volatile. Indexing Risk. An underlying fund is operated as a passively managed index fund and, therefore, the adverse performance of a particular security necessarily will not result in the elimination of the security from the underlying fund’s portfolio. Ordinarily, the underlying fund’s adviser will not sell the underlying fund’s portfolio securities except to reflect additions or deletions of the securities that comprise the underlying fund’s underlying index, or as may be necessary to raise cash to pay underlying fund shareholders who sell underlying fund shares. As such, the underlying fund will be negatively affected by declines in the securities represented by its underlying index. Also, there is no guarantee that the underlying fund’s adviser will be able to correlate the underlying fund’s performance with that of its underlying index. Issuer-Specific Changes Risk. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. Management Risk. An underlying fund is actively managed and depends heavily on an underlying fund’s adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for an underlying fund’s portfolio. An underlying fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of an underlying fund and, therefore, the ability of the underlying fund to achieve its investment objective. Market Risk. The market values of an underlying fund’s investments, and therefore the value of an underlying fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of an underlying fund’s investments may go up or down due to general market conditions which are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by an underlying fund will rise in value. Market Trading Risk. An underlying exchange-traded fund faces numerous market trading risks, including the potential lack of an active market for its shares, losses from trading in secondary markets, and disruption in the creation/redemption process of an underlying fund. Any of these factors may lead to an underlying fund’s shares trading at a premium or discount to an underlying fund’s net asset value (NAV). Non-Correlation Risk. An underlying fund’s return may not match the return of the underlying index for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the underlying index, and incurs costs in buying and selling securities, especially when rebalancing securities holdings to reflect changes in the composition of the index. In addition, the performance of the underlying fund and the underlying index may vary due to asset valuation differences and differences between the underlying fund’s portfolio and the index resulting from legal restrictions, costs or liquidity constraints. Non-Diversification Risk. An underlying fund is non-diversified and can invest a greater portion of its assets in the obligations or securities of a small number of issuers or any single issuer than a diversified fund can. A change in the value of one or a few issuers’ securities will therefore affect the value of an underlying fund more than would occur in a diversified fund. REIT Risk/Real Estate Risk. Investments in real estate related instruments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to an underlying fund’s holdings. Shares of real estate related companies, which tend to be small- and mid-cap companies, may be more volatile and less liquid. Sector Focus Risk. An underlying fund may from time to time invest a significant amount of its assets (i.e. over 25%) in one market sector or group of related industries. In this event, an underlying fund’s performance will depend to a greater extent on the overall condition of the sector or group of industries and there is increased risk that an underlying fund will lose significant value if conditions adversely affect that sector or group of industries. Small- and Mid-Capitalization Companies Risks. Small- and mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies, and their returns may vary, sometimes significantly, from the overall securities market. Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by an underlying fund. In certain circumstances, market quotations may not be readily available for some underlying fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Underlying fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that an underlying fund could sell a portfolio security for the value established for it at any time, and it is possible that an underlying fund would incur a loss because a security is sold at a discount to its established value. Valuation Time Risk. An underlying exchange-traded fund may invest in securities of foreign issuers and, because foreign exchanges may be open on days when an underlying fund does not price its shares, the value of the non-U.S. securities in an underlying fund’s portfolio may change on days when investors are not able to purchase or sell an underlying fund’s shares. As a result, trading spreads and the resulting premium or discount on an underlying fund’s shares may widen, and, therefore, increase the difference between the market price of an underlying fund’s shares and the NAV of such shares. Value Investing Style Risk. A value investing style subjects an underlying fund to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market.

[1] A contingent deferred sales charge may apply in some cases. See “Shareholder Account Information-Contingent Deferred Sales Charges (CDSCs).”

[2] Performance includes returns of the Fund’s Class A shares at net asset value and includes the 12b-1 fees applicable to that class. Class A shares’ performance reflects any applicable fee waivers and/or expense reimbursements.

[3] The Fund has changed its broad-based benchmark from the S&P 500® Index to the Bloomberg Barclays Global Aggregate Bond Index, Hedged and the MSCI All Country World Index, which it believes are more appropriate measures of the Fund’s performance. The Fund will not show performance for the S&P 500® Index in its next annual update.
