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 and/or the Adviser) and exchange-traded funds advised by Invesco PowerShares Capital Management LLC (PowerShares Capital) or other unaffiliated advisers (the underlying funds). Invesco and PowerShares Capital are affiliates of each other as they both are indirect wholly-owned subsidiaries of Invesco Ltd. The Fund's target allocation is to invest approximately 65%-75% of its total assets in underlying funds that invest primarily in equity securities (equity funds), approximately 5%-10% of its total assets in underlying funds that invest primarily in fixed-income securities (fixed-income funds) and approximately 20%-25% of its total assets in alternative asset classes and investment strategies which may include commodities.        Approximately 25%-30% of the assets that are invested will be allocated to underlying funds that invest primarily in foreign securities. Approximately 5%-7% of the assets that are invested in alternative asset classes will be allocated to underlying funds that invest primarily in commodities.        The Fund may also invest up to 20% of its total assets in affiliated or unaffiliated exchange-traded funds.        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 a quarterly 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 shareholder approval. A list of the underlying funds and their target weightings is located in the Fund's SAI.
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:        Call Risk. If interest rates fall, it is possible that issuers of debt securities with high interest rates will prepay or call their securities before their maturity dates. In this event, the proceeds from the called securities would likely be reinvested by an underlying fund in securities bearing the new, lower interest rates, resulting in a possible decline in an underlying fund's income and distributions to shareholders.        CFTC Regulation Risk. The Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is promulgating new rules, which will subject an underlying fund and its wholly-owned subsidiary to regulation by the CFTC. An underlying fund and its wholly-owned subsidiary will be required to operate subject to applicable CFTC requirements, including registration, disclosure and operational requirements. An underlying fund also will be subject to CFTC requirements related to processing derivatives transactions and tracking exposure levels to certain commodities. Compliance with these additional requirements will increase an underlying fund's expenses. Certain of the requirements that would apply to an underlying fund and its wholly-owned subsidiary have not yet been adopted, and it is unclear what the effect of those requirements would be on an underlying fund if they are adopted. The Adviser believes that it is possible that compliance with CFTC regulations, if they are adopted as proposed, may adversely affect the ability of an underlying fund to achieve its objective.        Commodity-Linked Notes Risk. An underlying fund's investments in commodity-linked notes may involve substantial risks, including risk of loss of a significant portion of their principal value. In addition to risks associated with the underlying commodities, they may be subject to additional special risks, such as the lack of a secondary trading market and temporary price distortions due to speculators and/or the continuous rolling over of futures contracts underlying the notes. Commodity-linked notes are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligation to complete the transaction with an underlying fund.        Commodity Risk. Invesco Balanced-Risk Allocation Fund's, an underlying fund, significant investment exposure to the commodities markets and/or a particular sector of the commodities markets, may subject the underlying fund to greater volatility than investments in traditional securities, such as stocks and bonds. The commodities markets may fluctuate widely based on a variety of factors, including 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 and investment and trading activities of mutual funds, hedge funds and commodities funds. Prices of various commodities may also be affected by factors such as drought, floods, weather, livestock disease, embargoes, tariffs and other regulatory developments. The prices of commodities can also fluctuate widely due to supply and demand disruptions in major producing or consuming regions. Because a certain underlying fund's performance is linked to the performance of potentially volatile commodities, investors should be willing to assume the risks of potentially significant fluctuations in the value of the underlying fund's shares.        Concentration Risk. To the extent an underlying fund invests a greater amount in any one sector or industry, an underlying fund's performance will depend to a greater extent on the overall condition of the sector or industry, and there is increased risk to an underlying fund if conditions adversely affect that sector or industry.        Convertible Securities Risk. An underlying fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.        Correlation Risk. Changes in the value of two investments or asset classes may not track or offset each other in the manner anticipated by the portfolio managers. Because an underlying fund's investment strategy seeks to balance risk across three asset classes and, within each asset class, to balance risk across different countries and commodities, to the extent either the three asset classes or the selected countries and commodities are correlated in a way not anticipated by the portfolio managers an underlying fund's risk allocation process may not succeed in achieving its investment objective.        Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to an underlying fund.        Credit Linked Notes Risk. Risks of credit linked notes include those risks associated with the underlying reference obligation including but not limited to market risk, interest rate risk, credit risk, default risk and foreign currency risk. In the case of a credit linked note created with credit default swaps, the structure will be "funded" such that the par amount of the security will represent the maximum loss that could be incurred on the investment and no leverage is introduced. An investor in a credit linked note bears counterparty risk or the risk that the issuer of the credit linked note will default or become bankrupt and not make timely payment of principal and interest of the structured security.        Credit Risk. The issuer of instruments in which an underlying fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer's credit rating.        Currency/Exchange Rate Risk. The dollar value of an underlying fund's foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.        Depositary Receipts Risk. Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts or to pass through to them any voting rights with respect to the deposited securities.        Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index, commodity or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. An underlying fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while an underlying fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the Adviser elects not to do so due to availability, cost, market conditions or other factors.        Developing/Emerging Markets Securities Risk. The prices of securities issued by foreign companies and governments located in developing/emerging markets countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.        Exchange-Traded Funds Risk. An investment by the Fund or underlying fund in exchange-traded funds generally presents the same primary risks as an investment in a mutual fund. In addition, an exchange-traded fund may be subject to the following: (1) a discount of the exchange-traded fund's shares to its net asset value; (2) failure to develop an active trading market for the exchange-traded fund's shares; (3) the listing exchange halting trading of the exchange-traded fund's shares; (4) failure of the exchange-traded fund's shares to track the referenced asset; and (5) holding troubled securities in the referenced index or basket of investments. Exchange-traded funds may involve duplication of management fees and certain other expenses, as the Fund or underlying fund indirectly bears its proportionate share of any expenses paid by the exchange-traded funds in which it invests. Further, certain of the exchange-traded funds in which the Fund or underlying fund may invest are leveraged. The more the Fund or underlying fund invests in such leveraged exchange-traded funds, the more this leverage will magnify any losses on those investments.        Exchange-Traded Notes Risk. Exchange-traded notes are subject to credit risk, including the credit risk of the issuer, and the value of the exchange-traded note may drop due to a downgrade in the issuer's credit rating, despite the underlying market benchmark or strategy remaining unchanged. The value of an exchange-traded note may also be influenced by time to maturity, level of supply and demand for the exchange-traded note, volatility and lack of liquidity in the underlying market, changes in the applicable interest rates, changes in the issuer's credit rating, and economic, legal, political, or geographic events that affect the referenced underlying market or strategy. Exchange-traded notes are also subject to counterparty risk.        Financial Institutions Risk. Investments in financial institutions may be subject to certain risks, including, but not limited to, the risk of regulatory actions, changes in interest rates and concentration of loan portfolios in an industry or sector. Financial institutions are highly regulated and may suffer setbacks should regulatory rules and interpretations under which they operate change. Likewise, there is a high level of competition among financial institutions which could adversely affect the viability of an institution.        Foreign Securities Risk. An underlying fund's foreign investments may be affected by changes in a foreign country's exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.        Fund of Funds Risk. The Fund's performance depends on the underlying funds in which it invests, and it is subject to the risks of the underlying funds. Market fluctuations may change the target weightings in the underlying funds. The underlying funds may change their investment objectives, policies or practices and may not achieve their investment objectives, all of which may cause the Fund to withdraw its investments therein at a disadvantageous time.        Geographic Focus Risk. From time to time an underlying fund may invest a substantial amount of its assets in securities of issuers located in a single country or a limited number of countries. If an underlying fund focuses its investments in this manner, it assumes the risk that economic, political and social conditions in those countries will have a significant impact on its investment performance. An underlying fund's investment performance may also be more volatile if it focuses its investments in certain countries, especially emerging markets countries.        Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.        High Yield Bond (Junk Bond) Risk. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time.        Indexing Risk. Unlike many investment companies, certain underlying exchange-traded funds do not utilize an investing strategy that seeks returns in excess of their benchmark indices. Such underlying exchange-traded funds would not necessarily buy or sell a security due to its general underperformance, unless that security is added to or removed from the applicable benchmark index.        Investing in the European Union Risk. Many countries in the European Union are susceptible to high economic risks associated with high levels of debt, notably due to investments in sovereign debts of European countries such as Greece, Italy and Spain. One or more member states might exit the European Union, placing its currency and banking system in jeopardy. The European Union faces major issues involving its membership, structure, procedures and policies, including the adoption, abandonment or adjustment of the new constitutional treaty, the European Union's enlargement to the south and east, and resolution of the European Union's problematic fiscal and democratic accountability. Efforts of the member states to further unify their economic and monetary policies may increase the potential for the downward movement of one member state's market to cause a similar effect on other member states' markets. European countries that are part of the European Economic and Monetary Union may be significantly affected by the tight fiscal and monetary controls that the union seeks to impose on its members.        Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. This risk may be magnified due to an underlying fund's use of derivatives that provide leveraged exposure to government bonds.        Issuer-Specific Changes. 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.        Leverage Risk. Leverage exists when an underlying fund purchases or sells an instrument or enters into a transaction without investing cash in an amount equal to the full economic exposure of the instrument or transaction and the underlying fund could lose more than it invested. Leverage created from borrowing or certain types of transactions or instruments may impair an underlying fund's liquidity, cause it to liquidate positions at an unfavorable time, increase volatility or otherwise not achieve its intended objective. An underlying fund's significant use of derivatives and leverage could, under certain market conditions, cause the underlying fund's losses to be more significant than other mutual funds.        Liquidity Risk. An underlying fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. An underlying fund's significant use of derivative instruments may cause liquidity risk to be greater than other mutual funds that invest in more traditional assets such as stocks and bonds, which trade on markets with more participants.        Management Risk. The investment techniques and risk analysis used by the Fund's and the underlying funds' portfolio managers may not produce the desired results. Because an underlying fund's investment process relies heavily on its asset allocation process, market movements that are counter to the portfolio managers' expectations may have a significant adverse effect on an underlying fund's net asset value. Further, the portfolio managers' use of instruments that provide economic leverage increases the volatility of an underlying fund's net asset value, which increases the potential of greater losses that may cause an underlying fund to liquidate positions when it may not be advantageous to do so.        Market Risk. The prices of and the income generated by the underlying funds' securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.        Market Trading Risk. Risk is inherent in all investing. An investment in an underlying fund involves risks similar to those of investing in any underlying fund of equity or fixed-income securities traded on exchanges. You should anticipate that the value of the shares will decline, more or less, in correlation with any decline in value of the underlying index of certain underlying exchange-traded funds.        Mortgage- and Asset-Backed Securities Risk. Certain of the underlying funds may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower's payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, an underlying fund may reinvest these early payments at lower interest rates, thereby reducing an underlying fund's income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of mortgage-backed securities and could result in losses to an underlying fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with lower capacity to make timely payments on their mortgages.        Non-Correlation Risk. The return of an underlying fund's preferred equity segment may not match the return of the Index for a number of reasons. For example, an underlying fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing securities holdings to reflect changes in the Index. In addition, the performance of the preferred equity segment and the Index may vary due to asset valuation differences and differences between the preferred equity segment and the Index resulting from legal restrictions, costs or liquidity constraints.        Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a small number of issuers or a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.        Preferred Securities Risk. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If an underlying fund owns a security that is deferring or omitting its distributions, an underlying fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.        Reinvestment Risk. Reinvestment risk is the risk that a bond's cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond.        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. Real estate companies, including REITs or similar structures, tend to be small and mid cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, an underlying fund may own real estate directly, which involves the following additional risks: environmental liabilities, difficulty in valuing and selling the real estate, and economic or regulatory changes.        Small- and Mid-Capitalization Risks. Stocks of small- and mid-sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small- and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.        Sovereign Debt Risk. Investments in foreign sovereign debt obligations involve certain risks in addition to those relating to foreign securities or debt securities generally. The issuer of the debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due in accordance with the terms of such debt, and an underlying fund may have limited recourse in the event of a default against the defaulting government. Without the approval of debt holders, some governmental debtors have in the past been able to reschedule or restructure their debt payments or declare moratoria on payments.        Subsidiary Risk. By investing in the Subsidiary, an underlying fund is indirectly exposed to risks associated with the Subsidiary's investments. The Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), and, except as otherwise noted in the underlying fund's prospectus, is not subject to the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands, under which the underlying fund and the Subsidiary, respectively, are organized, could result in the inability of the underlying fund and/or the Subsidiary to operate as described in the underlying fund prospectus and the SAI, and could negatively affect the underlying fund and its shareholders.        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 Invesco Balanced-Risk Allocation Fund, an underlying fund, from certain commodity-linked derivatives was treated as non-qualifying income, Invesco Balanced-Risk Allocation Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the fund level. Invesco Balanced-Risk Allocation Fund has received private letter rulings from the Internal Revenue Service confirming that income derived from its investments in the Subsidiary and a form of commodity-linked note constitutes qualifying income to Invesco Balanced-Risk Allocation Fund. However, the Internal Revenue Service has suspended issuance of any further private letter rulings pending a review of its position. Should the Internal Revenue Service issue guidance, or Congress enact legislation, that adversely affects the tax treatment of Invesco Balanced-Risk Allocation Fund's use of commodity-linked notes, or the Subsidiary, it could limit its ability to pursue its investment strategy. In this event, Invesco Balanced-Risk Allocation Fund's Board of Trustees may authorize a significant change in investment strategy or fund liquidation. Invesco Balanced-Risk Allocation Fund also may incur transaction and other costs to comply with any new or additional guidance from the Internal Revenue Service.        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 may authorize a significant change in investment strategy or fund liquidation.        U.S. Government Obligations Risk. An underlying fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect an underlying fund's ability to recover should they default.        Value Investing Style Risk. Certain of the underlying funds emphasize a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject 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. Value stocks also may decline in price, even though in theory they are already underpriced.        Volatility Risk. An underlying fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause an underlying fund's net asset value per share to experience significant increases or declines in value over short periods of time.
Risk Lose Money [Text]	rr_RiskLoseMoney	As with any mutual fund investment, loss of money is a risk of investing.
Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	Non-Diversification Risk. Certain of the underlying funds are non-diversified and can invest a greater portion of their assets in a small number of issuers or a single issuer. A change in the value of the issuer could affect the value of an underlying fund more than if it was a diversified fund.
