Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. 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 93% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_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. This Example does not represent the effect of any fees or expenses assessed in connection with your variable product, and if it did, expenses would be higher. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the contractual period above and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in investment-grade debt securities (generally referred to as "bonds"), and in derivatives and other instruments that have economic characteristics similar to such securities. A debt security is a security representing money borrowed by the issuer that must be repaid. The terms of a debt security specify the amount of principal, the interest rate or discount, and the time or times at which payments are due. Debt securities can include: Domestic and foreign corporate debt obligations; Domestic and foreign government debt obligations, including U.S. government securities; Mortgage-related securities; Asset-backed securities; and Other debt obligations. The portfolio managers’ overall strategy is to build a diversified portfolio of corporate and government bonds. The Fund’s investments in U.S. government securities may include securities issued or guaranteed by the U.S. government or by its agencies or federally-chartered entities referred to as “instrumentalities.” There is no required allocation of the Fund’s assets among the classes of securities, but the Fund focuses mainly on U.S. government securities and investment-grade corporate debt securities. When market conditions change, the portfolio managers might change the Fund’s relative asset allocation. The Fund invests in securities that are rated investment-grade at the time of purchase. Investment-grade securities are considered to be those instruments that are rated BBB- or higher by S&P Global Ratings (S&P), or Baa3 or higher by Moody’s Investors Service (Moody’s), or the equivalent by another nationally recognized statistical rating organization (NRSRO). The Fund may also invest in unrated securities, in which case the Fund’s investment adviser, Invesco Advisers, Inc. (Invesco or the Adviser), may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade categories similar to those of NRSROs. There can be no assurance, nor is it intended, that the Adviser’s credit analysis is consistent or comparable with the credit analysis process used by a NRSRO. In the event that a security receives different ratings from different NRSROs, the Fund will treat the security as being rated in the highest rating category received from an NRSRO. The Fund may also invest in illiquid or thinly traded securities. The Fund may also invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended. The Fund has no limitations on the range of maturities of the debt securities in which it can invest and may hold securities with short-, medium- or long-term maturities. The maturity of a security differs from its effective duration, which attempts to measure the expected volatility of a security’s price to interest rate changes. For example, if a bond has an effective duration of three years, a 1% increase in general interest rates would be expected to cause the bond’s value to decrease about 3%. To try to decrease volatility, the Fund seeks to maintain a weighted average effective portfolio duration of three to seven years, measured on a dollar-weighted basis using the effective duration of the securities included in its portfolio and the amount invested in each of those securities. However, the duration of the portfolio might not meet that target due to market events or interest rate changes that cause debt securities to be repaid more rapidly or more slowly than expected. The Fund may invest in foreign debt securities, including securities issued by foreign governments or companies in both developed and emerging markets. The Fund may also use derivatives to seek increased returns or to try to manage investment risks. Futures, swaps, forward contracts and “structured” notes are examples of some of the types of derivatives the Fund can use. In selecting investments for the Fund, the Fund’s portfolio managers analyze the overall investment opportunities and risks in different sectors of the debt securities markets by focusing on business cycle analysis and relative values between the corporate and government sectors. The Fund mainly seeks income earnings on the Fund’s investments plus capital appreciation that may arise from decreases in interest rates, from improving credit fundamentals for a particular sector or security or from other investment techniques. The Fund may sell securities that the portfolio managers believe no longer meet the above criteria.
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. The principal risks of investing in the Fund are: Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund’s income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer’s credit rating, for any reason, can also reduce the market value of the issuer’s securities. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall. Fixed-Income Market Risks. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable capital gain distributions to shareholders, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates. Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments. Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight. Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or 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. 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 securities of issuers in developing or emerging market countries may be considered speculative. Risks of Derivative Investments. Derivatives may involve significant risks. Derivatives may be more volatile than other types of investments, may require the payment of premiums, may increase portfolio turnover, may be illiquid, and may not perform as expected. Derivatives are subject to counterparty risk and the Fund may lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful. In addition, pursuant to rules implemented under financial reform legislation, certain over-the-counter derivatives are required to be executed on a regulated market and/or cleared through a clearinghouse. Entering into a derivative transaction with a clearinghouse may entail further risks and costs. Investments in Other Investment Companies. The Fund can also invest in the securities of other investment companies, which can include open-end funds, closed-end funds, unit investment trusts and business development companies subject to the limits of the Investment Company Act of 1940. One reason the Fund might do so is to gain exposure to segments of the markets represented by another fund, at times when the fund might not be able to buy the particular type of securities directly. As a shareholder of an investment company, the Fund would be subject to its ratable share of that investment company’s expenses, including its advisory and administration expenses. The Fund does not intend to invest in other investment companies unless it is believed that the potential benefits of the investment justify the expenses. The Fund’s investments in the securities of other investment companies are subject to the limits that apply to those types of investments under the Investment Company Act of 1940. Risks of Restricted Securities. Securities that have limitations on their resale are referred to as “restricted securities” because they are not registered for sale to the general public and may only be resold to certain qualified institutional buyers. These types of securities may require special registration and pose valuation difficulties. Mortgage-Related Securities. The Fund can buy interests in pools of residential or commercial mortgages in the form of “passthrough” mortgage securities. They may be issued or guaranteed by the U.S. government, or its agencies and instrumentalities, or by private issuers, such as corporations, banks, savings and loans, mortgage bankers and other non-governmental issuers. Mortgage-related securities may be issued in different series, each having different interest rates and maturities. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are subject to the risks of unanticipated prepayment and extension risks .Mortgage-backed securities are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and maybe less liquid than the markets for other types of securities. The liquidity of mortgage-backed securities may change over time. Asset-Backed Securities Risk. Asset-backed securities are fractional interests in pools of loans, receivables or other assets. They are issued by trusts or other special purpose vehicles and are collateralized by the loans, receivables or other assets that make up the pool. The trust or other issuer passes the income from the underlying asset pool to the investor. Neither the Fund nor the investment adviser selects the loans, receivables or other assets that are included in the pools or the collateral backing those pools. Asset-backed securities are subject to interest rate risk and credit risk. These securities are subject to the risk of default by the issuer as well as by the borrowers of the underlying loans in the pool. Certain asset-backed securities are subject to prepayment and extension risks. Management Risk. The Fund is actively managed and depends heavily on the 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. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective. 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 which are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Total Return Bond Fund/VA (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the “Reorganization”). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the Series I shares of the Fund and the Non-Service Shares of the predecessor fund from year to year as of December 31. The performance table compares the predecessor fund’s and the Fund’s performance to that of a broad measure of market performance and additional indices with characteristics relevant to the Fund. For more information on the benchmarks used see the “Benchmark Descriptions” section of the prospectus. The bar chart and performance table below do not reflect charges assessed in connection with your variable product; if they did, the performance shown would be lower. The Fund’s (and the predecessor fund’s) past performance is not necessarily an indication of how the Fund will perform in the future. The returns shown for periods ending on or prior to May 24, 2019 are those of the Non-Service Shares and Service Shares of the predecessor fund, and are not offered by the Fund. The Non-Service Shares of the predecessor fund were reorganized into Series I shares of the Fund and the Service Shares of the predecessor fund were reorganized into the Series II shares of the Fund after the close of business on May 24, 2019. Series I shares’ and Series II shares’ returns of the Fund will be different from the Non-Service Shares’ and the Service Shares’ returns of the predecessor fund as they have different expenses. All performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses. The Series I shares and Series II shares invest in the same portfolio of securities and will have substantially similar performance, except to the extent that the expenses borne by each share class differ. Series II shares have higher expenses (and therefore lower performance) resulting from its Rule 12b-1 plan, which provides for a maximum fee equal to an annual rate of 0.25% (expressed as a percentage of average daily net assets of the Fund).

[1] Invesco Advisers, Inc. (“Invesco” or the “Adviser”) has contractually agreed to waive advisory fees and/or reimburse expenses of Series I and Series II shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding Acquired Fund Fees and Expenses and certain items discussed below) of Series I and Series II shares to 0.75% and 1.00%, respectively, of the Fund’s average daily net assets (the “expense limits”). In determining the Adviser’s obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to exceed the numbers reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items, including litigation expenses; (v) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Invesco has also contractually agreed to waive a portion of the Fund’s management fee in an amount equal to the net management fee that Invesco earns on the Fund’s investments in certain affiliated funds, which will have the effect of reducing Acquired Fund Fees and Expenses. Unless Invesco continues the fee waiver agreements, they will terminate on May 31, 2021 and June 30, 2021, respectively. During their terms, the fee waiver agreements cannot be terminated or amended to increase the expense limits or reduce the advisory fee waiver without approval of the Board of Trustees.
