Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock
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 [Heading] oef_PortfolioTurnoverHeading Portfolio Turnover.
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 1% of the average value of its portfolio.
Portfolio Turnover, Rate oef_PortfolioTurnoverRate 1.00%
Strategy [Heading] oef_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks of companies included in the S&P 500® Index (the Underlying Index), and in derivatives and other instruments that have economic characteristics similar to such securities. The Underlying Index is comprised of common stocks of approximately 500 large-capitalization companies that generally represent the large-cap segment of the U.S. equity market. The Underlying Index employs a float-adjusted market capitalization weighted methodology, with larger companies generally receiving greater weights.
In seeking to track the investment results (before fees and expenses) of the Underlying Index, the portfolio managers primarily utilize a “full replication” methodology, pursuant to which the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index.
The Underlying Index is typically rebalanced quarterly. There is no regularly scheduled reconstitution of the Underlying Index; rather, changes to the composition of the Underlying Index are made on an as-needed basis in accordance with the index provider’s methodology. The Fund is generally rebalanced in accordance with the Underlying Index. Constituent changes are generally incorporated in the Fund as and when they are made to the Underlying Index.
The Fund can invest in derivative instruments including futures contracts.
The Fund can use futures contracts, including index futures, to seek exposure to certain equity securities represented in the Underlying Index while managing cash balances.
Bar Chart and Performance Table [Heading] oef_BarChartAndPerformanceTableHeading Performance Information
Performance Narrative [Text Block] oef_PerformanceNarrativeTextBlock
The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund's performance to that of a broad-based securities market benchmark. The Fund's past performance (before and after taxes) is not necessarily an indication of its future performance.
Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements.
All Fund performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses.

Risk [Text Block] oef_RiskTextBlock Market Risk. The market values of the Fund’s investments, and therefore the value of the 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 the Fund’s investments may go up or down due to general market conditions that 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, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally. 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 the Fund will rise in value.

Risk [Text Block] oef_RiskTextBlock Investing in Stocks Risk. The value of the 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 Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, the Fund would not necessarily buy or sell a security unless that security is added to or removed from, respectively, the Underlying Index, even if that security generally is underperforming. Additionally, the Fund generally rebalances its portfolio in accordance with the Underlying Index, and, therefore, any changes to the Underlying Index’s rebalance schedule will typically result in corresponding changes to the Fund’s rebalance schedule.

Risk [Text Block] oef_RiskTextBlock Sector Focus Risk. The Fund may from time to time have a significant amount of its assets invested in one market sector or group of related industries. In this event, the 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 the Fund will lose significant value if conditions adversely affect that sector or group of industries.
INVESCO S&P 500 INDEX FUND | INVESCO S&P 500 INDEX FUND | Derivatives Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
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 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 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 Fund’s returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and 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 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 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.
INVESCO S&P 500 INDEX FUND | INVESCO S&P 500 INDEX FUND | Non-Correlation Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing and reconstituting the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.
