This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.
The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.
Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover 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 86% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
The Fund is a “fund of funds,” and may invest its assets in underlying open-end and closed-end funds (including unlisted interval funds) advised by Invesco Advisers, Inc. (Invesco or the Adviser), including exchange-traded funds (ETFs), and other pooled investment vehicles advised by Invesco Capital Management LLC (Invesco Capital), or underlying open-end and closed-end funds, including 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 invests its assets in a selection of underlying funds which invest primarily in international or domestic equities and fixed-income securities. The Fund’s target allocation is to invest 60%-70% of its total assets in underlying funds that invest primarily in fixed-income securities and 30%-40% of its total assets in underlying funds that invest primarily in equity securities, which may include real estate investment trusts (REITs).
The Adviser uses a three-step process to create the Fund's portfolio including: (1) determining strategic return drivers 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.
The Adviser rebalances the Fund’s investments in the underlying funds on a periodic 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 [Text Block] oef_RiskTextBlock
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 that are not specifically related to the particular issuer. These market conditions may include real or perceived adverse economic conditions, changes in trade regulation or economic sanctions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability and uncertainty, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally, among others. Certain changes in the U.S. economy in particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which an underlying fund has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
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.

Risk [Text Block] oef_RiskTextBlock
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.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Exchange-Traded Funds Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Index Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Index Risk. Unlike many investment companies that are “actively managed,” certain underlying funds are “passive” investors and therefore do not utilize investing strategies that seek returns in excess of their respective Underlying Index. Therefore, an underlying fund would not necessarily buy or sell a security unless that security is added or removed, respectively, from its respective Underlying Index, even if that security generally is underperforming. If a specific security is removed from an Underlying Index, certain underlying funds may be forced to sell shares of the security at an inopportune time or for a price lower than the security’s current market value. An Underlying Index may not contain the appropriate mix of securities for any particular economic cycle. Unlike with an actively managed fund, the
Adviser does not use techniques or defensive strategies designed to lessen the impact of periods of market volatility or market decline. This means that, based on certain market and economic conditions, an underlying fund’s performance could be lower than other types of mutual funds with investment advisers that actively manage their portfolio assets to take advantage of market opportunities.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Allocation Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Debt Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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 credit analysis applied to an underlying fund’s debt securities 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.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Changing Fixed Income Market Conditions Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Changing Fixed Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed income investments, particularly those with longer maturities. Such changes and resulting increased volatility may adversely impact an underlying fund, including its operations, universe of potential investment options, and return potential. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of an underlying fund’s investments may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the financial markets, which could result in higher than normal redemptions by shareholders, which could potentially increase an underlying fund’s transaction costs.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Mortgage- and Asset-Backed Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities are subject to prepayment or call risk, which is the risk that a borrower's payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. This could result in an underlying fund reinvesting these early payments at lower interest rates, thereby reducing an underlying fund's income. Mortgage- and asset-backed securities also are subject to extension risk, which is the risk that an unexpected rise in interest rates could reduce the rate of prepayments, causing the price of the mortgage- and asset-backed securities and an underlying fund’s share price to fall. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool will adversely affect the value of mortgage-backed securities and will result in losses to an underlying fund. Privately-issued mortgage-backed securities and asset-backed securities may be less liquid than other types of securities and an underlying fund may be unable to sell these securities at the time or
price it desires. During periods of market stress or high redemptions, an underlying fund may be forced to sell these securities at significantly reduced prices, resulting in losses. Liquid privately-issued mortgage-backed securities and asset-backed securities can become illiquid during periods of market stress. Privately issued mortgage-related securities are not subject to the same underwriting requirements as those with government or government-sponsored entity guarantees and, therefore, mortgage loans underlying privately issued mortgage-related securities may have less favorable collateral, credit risk, liquidity risk or other underwriting characteristics, and wider variances in interest rate, term, size, purpose and borrower characteristics. An underlying fund may invest in mortgage pools that include subprime mortgages, which are loans made to borrowers with weakened credit histories or with lower capacity to make timely payments on their mortgages. Liquidity risk is even greater for mortgage pools that include subprime mortgages.

Risk [Text Block] oef_RiskTextBlock
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and an underlying fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Senior Loans and Other Loans Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Senior Loans and Other Loans Risk. Risks associated with an investment in Senior Loans include credit risk, interest rate risk, liquidity risk, valuation risk and prepayment risk. These risks are typically associated with debt securities but may be heightened in part because of the limited public information regarding Senior Loans. Senior Loans generally are floating rate loans, which are subject to interest rate risk as the interest paid on the floating rate loans adjusts periodically based on changes in widely accepted reference rates. Lack of an active trading market, restrictions on resale, irregular trading activity, wide bid/ask spreads and extended trade settlement periods may impair an underlying fund’s ability to sell Senior Loans within its desired time frame or at an acceptable price and its ability to accurately value existing and prospective investments. Extended trade settlement periods may result in cash not being immediately available to an underlying fund. As a result, an underlying fund may have to sell other investments or engage in borrowing transactions to raise cash to meet its obligations. The risk of holding Senior Loans is also directly tied to the risk of insolvency or bankruptcy of the issuing banks. The value of Senior Loans can be affected by and sensitive to changes in government regulation and to economic downturns in the United States and abroad. Senior loans are also subject to the risk that a court could subordinate a senior loan or take other action detrimental to the holders of senior loans. Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. Loan investments are often issued in connection with highly leveraged transactions which are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy. Highly leveraged loans also may be less liquid than other loans. These risks could cause an underlying fund to lose income or principal on a particular investment, which in turn could affect an underlying fund’s returns. Newly originated loans (including reissuances and restructured loans) may possess lower levels of credit document protections than has historically been the case. Accordingly, in the event of default an underlying fund may experience lower levels of recoveries than has historically been the norm.

Collateralized Loan Obligations Risk. CLOs are subject to the risks of substantial losses due to actual defaults by underlying borrowers, which will be greater during periods of economic or financial stress. CLOs
may also lose value due to collateral defaults and disappearance of subordinate tranches, market anticipation of defaults, and investor aversion to CLO securities as a class. The risks of CLOs will be greater if an underlying fund invests in CLOs that hold loans of uncreditworthy borrowers or if an underlying fund holds subordinate tranches of the CLO that absorb losses from the defaults before senior tranches. In addition, CLOs carry risks including interest rate risk and credit risk.

High Yield Debt Securities (Junk Bond/Below-Investment Grade) Risk. Investments in high yield debt securities (junk bonds) and other lower-rated securities will subject an underlying fund to substantial risk of loss. These securities are considered to be speculative with respect to the issuer’s ability to pay interest and principal when due, are more susceptible to default or decline in market value and are less liquid than investment grade debt securities. Prices of high yield debt securities tend to be very volatile.

U.S. Government Obligations Risk. Obligations of U.S. government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. government, which could affect an underlying fund’s ability to recover should they default. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Risk [Text Block] oef_RiskTextBlock
Subordinated Debt Risk. Perpetual subordinated debt is a type of hybrid instrument that has no maturity date for the return of principal and does not need to be redeemed by the issuer. These investments typically have lower credit ratings and lower priority than other obligations of an issuer during bankruptcy, presenting a greater risk for nonpayment. This risk increases as the priority of the obligation becomes lower. Payments on these securities may be subordinated to all existing and future liabilities and obligations of subsidiaries and associated companies of an issuer. Additionally, some perpetual subordinated debt does not restrict the ability of an issuer’s subsidiaries to incur further unsecured indebtedness.

INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Unrated Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Unrated Securities Risk. Because an underlying fund purchases securities that are not rated by any nationally recognized statistical rating organization, the investment adviser may internally assign ratings to those securities, after assessing their credit quality and other factors, in categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the investment adviser’s credit analysis process is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization. Unrated securities are considered “investment-grade” or “below-investment-grade” if judged by the investment adviser to be comparable to rated investment- grade or below-investment-grade securities. The investment adviser’s rating does not constitute a guarantee of the credit quality. In addition, some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that an underlying fund might have difficulty selling them promptly at an acceptable price.

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, in some cases, foreign currency risk. 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 linked notes may be less liquid than other investments and therefore harder to dispose of at the desired time and price. In addition, credit linked notes may be leveraged and, as a result, small changes in the value of the underlying reference obligation may produce disproportionate losses to an underlying fund.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | TBA Transactions Risk [Member]

Risk [Text Block] oef_RiskTextBlock
TBA Transactions Risk. TBA transactions involve the risk of loss if the securities received are less favorable than what was anticipated by an
underlying fund when entering into the TBA transaction, or if the counterparty fails to deliver the securities. When an underlying fund enters into a short sale of a TBA mortgage it does not own, an underlying fund may have to purchase deliverable mortgages to settle the short sale at a higher price than anticipated, thereby causing a loss. As there is no limit on how much the price of mortgage securities can increase, an underlying fund’s exposure is unlimited. An underlying fund may not always be able to purchase mortgage securities to close out the short position at a particular time or at an acceptable price. In addition, taking short positions results in a form of leverage, which could increase the volatility of an underlying fund’s share price.

Zero Coupon or Pay-In-Kind Securities Risk. The value, interest rates, and liquidity of non-cash paying instruments, such as zero coupon and pay-in-kind securities, are subject to greater fluctuation than other types of securities. The higher yields and interest rates on pay-in-kind securities reflect the payment deferral and increased credit risk associated with such instruments and that such investments may represent a higher credit risk than loans that periodically pay interest.

Dollar Roll Transactions Risk. Dollar roll transactions occur in connection with TBA transactions and involve the risk that the market value of the securities an underlying fund is required to purchase may decline below the agreed upon purchase price of those securities. Dollar roll transactions add a form of leverage to an underlying fund’s portfolio, which may make the Fund’s returns more volatile and increase the risk of loss. In addition, dollar roll transactions may increase an underlying fund’s portfolio turnover, which may result in increased brokerage costs and may lower an underlying fund’s actual return.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Investing in Stocks Risk. The value of an underlying fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall or rise sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.
The prices of individual stocks generally do not all move in the same direction at the same time. However, individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

Risk [Text Block] oef_RiskTextBlock
Growth Investing Risk. If a growth company’s earnings or stock price fails to increase as anticipated, or if its business plans do not produce the expected results, the value of its securities may decline sharply. Growth companies may be newer or smaller companies that may experience greater stock price fluctuations and risks of loss than larger, more established companies. Newer growth companies tend to retain a large part of their earnings for research, development or investments in capital assets. Therefore, they may not pay any dividends for some time. Growth investing has gone in and out of favor during past market cycles and is likely to continue to do so. During periods when growth investing is out of favor or when markets are unstable, it may be more difficult to sell growth company securities at an acceptable price and the securities of growth companies may underperform the securities of value companies or the overall stock market. Growth stocks may also be more volatile than other securities because of investor speculation.

Value Investing Risk. Value investing entails the risk that if the market does not recognize that a selected security is undervalued, the
prices of that security might not appreciate as anticipated. A value approach could also result in fewer investments that increase rapidly during times of market gains and could cause an underlying fund to underperform funds that use a growth or non-value approach to investing. Value investing has gone in and out of favor during past market cycles and when value investing is out of favor or when markets are unstable, the securities of value companies may underperform the securities of growth companies or the overall stock market.

Equity Linked Notes Risk. Investments in ELNs are susceptible to the risks of their underlying securities or index, which could include management risk, market risk and, as applicable, foreign securities and currency risks. ELNs are also subject to certain debt securities risks, such as interest rate and credit risks. Should the prices of the underlying securities or index move in an unexpected manner, an underlying fund may not achieve the anticipated benefits of an investment in an ELN, and may realize losses, which could be significant and could include an underlying fund's entire principal investment. An ELN investment is also subject to counterparty risk, which is the risk that the issuer of the ELN will default or become bankrupt and an underlying fund may not be repaid the principal amount of, or income from, its investment. ELNs utilized by an underlying fund may involve synthetic exposure to options that can create economic leverage risk which, depending on the performance of the underlying securities or index, could magnify or otherwise increase investment losses to an underlying fund and result in losses on the ELN that exceed the losses on the underlying securities or index. The economic leverage associated with investments in ELNs is distinguishable from indebtedness leverage in that it does not expose an underlying fund to losing more than the principal amount of the ELN. In addition, investments in ELNs allow for enhanced yield but are subject to limited upside appreciation potential based on movements of the underlying securities or index. ELNs may also be less liquid than more traditional investments and an underlying fund may be unable to sell ELNs at a desirable time or price. Further, the price of ELNs may not correlate with the underlying securities, index or a fixed income investment. Unlike a direct investment in equity securities, ELNs have a maturity date, potentially increasing an underlying fund’s turnover rate, transaction costs and tax liability. Investing in ELNs may be more costly to an underlying fund than if an underlying fund had invested in the underlying securities or index directly. By attaining this investment exposure synthetically through an ELN, rather than directly, 100% of the yield arising from the ELN’s stated coupon is treated as ordinary income for U.S. federal income tax purposes, which is consistent with an underlying fund’s investment objective to maximize income. Conversely, the U.S. federal income tax consequences of attaining the investment exposure directly ordinarily will give rise to capital gains.

Risk [Text Block] oef_RiskTextBlock
Short Position Risk. Because an underlying fund’s potential loss on a short position arises from increases in the value of the asset sold short, the underlying fund will incur a loss on a short position, which is theoretically unlimited, if the price of the asset sold short increases from the short sale price. The counterparty to a short position or other market factors may prevent an underlying fund from closing out a short position at a desirable time or price and may reduce or eliminate any gain or result in a loss. In a rising market, an underlying fund’s short positions will cause the underlying fund to underperform the overall market and its peers that do not engage in shorting. If an underlying fund holds both long and short positions, and both positions decline simultaneously, the short positions will not provide any buffer (hedge) from declines in value of the underlying fund’s long positions. Certain types of short positions involve leverage, which may exaggerate any losses, potentially more than the actual cost of the investment, and will increase the volatility of an underlying fund’s returns.

Risk [Text Block] oef_RiskTextBlock
Dividend Risk. As a group, securities that pay high dividends may fall out of favor with investors and underperform companies that do not pay high dividends. Also, changes in the dividend policies of such companies and the capital resources available for such companies’ dividend payments may affect an underlying fund. There is the possibility that dividend-paying
companies could reduce or eliminate the payment of dividends in the future or an anticipated acceleration of dividends may not occur. Depending on market conditions, dividend paying stocks that meet an underlying fund’s investment criteria may not be widely available for purchase by an underlying fund, which may increase the volatility of an underlying fund’s returns and limit its ability to produce current income while remaining fully diversified. High-dividend stocks may not experience high earnings growth or capital appreciation. An underlying fund’s performance during a broad market advance could suffer because dividend paying stocks may not experience the same capital appreciation as non-dividend paying stocks.

REIT Risk/Real Estate Risk. Investments in real estate related instruments may be adversely affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies. Shares of real estate related companies, which tend to be small- and mid-cap companies, may be more volatile and less liquid than larger companies. If a real estate related company defaults on certain types of debt obligations, held by an underlying fund, an underlying fund may acquire real estate directly, which involves additional risks such as environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Unlisted Closed-end Interval Fund Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Unlisted Closed-end Interval Fund Risk. In addition to the risks associated with the underlying assets held by an underlying unlisted closed-end interval fund (an underlying interval fund), an underlying interval fund is considered an illiquid investment because shareholders (such as the Fund) cannot redeem or sell their shares outside of periodic repurchase offers. To provide some liquidity to its shareholders, an underlying interval fund makes periodic offers to repurchase a portion of its outstanding shares at net asset value (NAV), subject to certain conditions under the 1940 Act. In connection with any given repurchase offer, it is possible that an underlying interval fund may offer to repurchase only a small portion of its outstanding shares. Further, if a repurchase offer is oversubscribed, shareholders of an underlying interval fund may only have a portion of their shares repurchased. As a result, there is no guarantee that shareholders of an underlying interval fund will be able to exit their shares at any given time. Since an underlying interval fund does not list its shares for trading on any national securities exchange, an underlying interval fund's shares are, therefore, not readily marketable and no market is expected to develop.

Liquidity Risk. An underlying fund may be unable to sell illiquid investments at the time or price it desires and, as a result, could lose its entire investment in such investments. Liquid securities can become illiquid during periods of market stress. If a significant amount of an underlying fund’s securities become illiquid, an underlying fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Issuer Focus Risk. Although an underlying fund is classified as a diversified fund, it may focus its investments in a relatively small number of issuers. The greater an underlying fund's exposure to any single investment or issuer, the greater the losses an underlying fund may experience upon any single economic, market, business, political, regulatory, or other occurrence. As a result, there may be more fluctuation in the price of an underlying fund's shares.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Foreign Securities Risk [Member]

Risk [Text Block] oef_RiskTextBlock
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. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls, and may therefore be more susceptible to fraud or corruption. There may be less public information available about foreign companies than U.S. companies, making it difficult to evaluate those foreign companies. Unless an underlying
fund has hedged its foreign currency exposure, 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.

Risk [Text Block] oef_RiskTextBlock
Emerging Market 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. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede an underlying fund’s ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions (including bankruptcy, confiscatory taxation, expropriation, nationalization of a company’s assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures and practices such as share blocking), or to obtain information needed to pursue or enforce such actions, may be limited. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

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.

Preferred Securities Risk. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. Preferred securities also may be subordinated to bonds or other debt instruments, subjecting them to a greater risk of non-payment, may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer.

Risk [Text Block] oef_RiskTextBlock
Small- and Mid-Capitalization Companies Risk. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Stocks of 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. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Smaller companies’ securities often trade in lower volumes and in many instances, are traded over-the-counter or on a regional securities exchange, where the frequency and volume of trading is substantially less than is typical for securities of larger companies traded on national securities exchanges. Therefore, the securities of smaller companies may be subject to wider price fluctuations and it might be harder for an underlying fund to
dispose of its holdings at an acceptable price when it wants to sell them. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. It may take a substantial period of time to realize a gain on an investment in a small- or mid-cap company, if any gain is realized at all.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Alternative Investment Strategies Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Alternative Investment Strategies Risk. An underlying fund utilizes alternative investment strategies, which are strategies that the portfolio manager expects to result in investment performance that does not correlate with the performance of traditional asset classes, such as equity and fixed-income investments. An underlying fund also seeks to utilize a diverse mix of alternative investment strategies, in the hope that individual strategies yield low performance correlation to other alternative investment strategies used by an underlying fund. However, alternative investments may be more volatile or illiquid, particularly during periods of market instability, and an underlying fund cannot guarantee that diverse alternative investment strategies will yield uncorrelated performance under all market conditions. In addition, the particular mix of alternative investments in an underlying fund’s portfolio may not be sufficiently diversified. An underlying fund is subject to the risk that its alternative investments may undergo a correlation shift, resulting in returns that are correlated with the broader market and/or with an underlying fund’s other alternative investments.

Quantitative Models Risk. Quantitative models are based upon many factors that measure individual securities relative to each other. Quantitative models may be highly reliant on the gathering, cleaning, culling and analysis of large amounts of data from third parties and other external sources. Any errors or imperfections in the factors, or the data on which measurements of those factors are based, could adversely affect the use of the quantitative models. The factors used in models may not identify securities that perform well in the future, and the securities selected may perform differently from the market as a whole or from their expected performance.

Risk [Text Block] oef_RiskTextBlock
When-Issued, Delayed Delivery and Forward Commitment Risks. When-issued and delayed delivery transactions subject an underlying fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because an underlying fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on an underlying fund because an underlying fund commits to purchase securities that it does not have to pay for until a later date, which increases an underlying fund’s overall investment exposure and, as a result, its volatility.

Infrastructure-Related Companies Risk. An underlying fund will concentrate its investments in the infrastructure industry. Infrastructure-related companies are subject to a variety of risk factors, including costs associated with environmental, governmental and other regulations, high interest costs for capital construction programs, high leverage, the effects of economic slowdowns, surplus capacity, increased competition, fluctuations of fuel prices, the effects of energy conservation policies, unfavorable tax laws or accounting policies, environmental damage, difficulty in raising capital, increased susceptibility to terrorist acts or political actions, and general changes in market sentiment towards infrastructure assets.
INVESCO Income Allocation Fund | INVESCO Income Allocation Fund | Derivatives Risk [Member]

Risk [Text Block] oef_RiskTextBlock
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 or the 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 or the 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 or the 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 or the 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 or the 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 or the 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. These risks are greater for certain underlying funds than mutual funds that do not use derivative instruments or that use derivative instruments to a lesser extent than certain underlying funds to implement their investment strategies.

Risk [Text Block] oef_RiskTextBlock
Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or group of industries. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or group of industries, an underlying fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or group of industries, an underlying fund faces more risks than if it were diversified broadly over numerous industries or groups of industries. 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 group of industries. In addition, at times, such industry or group of industries may be out of favor and underperform other industries, groups of industries or the market as a whole.

Risk [Text Block] oef_RiskTextBlock
Issuer-Specific Changes Risk. The performance of an an underlying fund depends on the performance of individual securities to which an an underlying fund has exposure. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform worse than the market as a whole, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Risk [Text Block] oef_RiskTextBlock
Borrowing Risk. Borrowing money to buy securities exposes an underlying fund to leverage and will cause an underlying fund’s share price to be more volatile because leverage will exaggerate the effect of any increase or decrease in the value of an underlying fund’s portfolio securities. Borrowing money may also require an underlying fund to liquidate positions
when it may not be advantageous to do so. In addition, an underlying fund will incur interest expenses and other fees on borrowed money. There can be no assurance that an underlying fund’s borrowing strategy will enhance and not reduce the underlying fund’s returns.

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.

Money Market Fund Risk. The share price of certain underlying money market funds may fluctuate and the Fund may lose money by investing in an underlying money market fund. The share price of money market funds can fall below the $1.00 share price. An underlying money market fund’s sponsor is not required to reimburse an underlying money market fund for losses, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to an underlying money market fund or maintain an underlying money market fund’s $1.00 share price at any time. The credit quality of an underlying money market fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on an underlying money market fund’s share price. An underlying money market fund’s share price can also be negatively affected during periods of high redemption pressures, illiquid markets, and/or significant market volatility. An underlying money market fund’s Board may elect to impose a fee upon the sale of the Fund’s shares or temporarily suspend the Fund’s ability to sell shares in the future if an underlying money market fund’s liquidity falls below required minimums because of market conditions or other factors.

Management Risk. The Fund is actively managed and depends heavily on its Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. Similarly, certain underlying funds are actively managed and depend heavily on their advisers’ judgments about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for their portfolios. The Fund and certain underlying funds could experience losses if these judgments prove to be incorrect. Because the investment process of the Fund relies heavily on its asset allocation process, market movements that are counter to the portfolio managers' expectations may have a significant adverse effect on the Fund’s net asset value. Similarly, because the investment processes of certain underlying funds rely heavily on their security selection processes, market movements that are counter to the portfolio managers' expectations may have a significant adverse effect on certain underlying funds’ net asset values. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and underlying funds and, therefore, their abilities to achieve their investment objectives.

[1] A contingent deferred sales charge may apply in some cases. See “Shareholder Account Information-Contingent Deferred Sales Charges (CDSCs).”
[2] “Other Expenses” have been restated to reflect current fees.
[3] Custom Invesco Income Allocation Index is composed of the following indexes: S&P 500® Index (reflects no deduction for fees, expenses or taxes), MSCI EAFE® Index (Net) (reflects reinvested dividends net of withholding taxes, but reflects no deduction for fees, expenses or other taxes), FTSE NAREIT Equity REITs Index (reflects no deduction for fees, expenses or other taxes) and Bloomberg U.S. Universal Index (reflects no deduction for fees, expenses or other taxes). The composition of the index may change based on the Fund's target asset allocation. The current composition of the index does not reflect its historical composition and will likely be altered in the future to better reflect the Fund's objectives.
[4] Performance shown on or prior to Class R6 shares' inception date is that of the Fund's Class A shares at net asset value and includes the 12b-1 fees applicable to that class. Although invested in the same portfolio of securities, Class R6 shares' returns of the Fund will be different from Class A shares' returns of the Fund as they have different expenses.
