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 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. 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 101% 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 invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of real estate and real estate-related issuers, and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund invests primarily in real estate investment trusts (REITs) and equity securities (including common and preferred stock, and convertible
securities) of domestic and foreign issuers. The Fund’s common stock investments may also include China A-shares (shares of companies based in mainland China that trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange).
The Fund concentrates its investments in the securities of domestic and foreign real estate and real estate-related companies. The Fund considers an issuer to be a real estate or real estate-related company if at least 50% of its assets, gross income or net profits are attributable to ownership, construction, management or sale of residential, commercial or industrial real estate. These issuers include (i) REITs or other real estate operating companies that (a) own property, (b) make or invest in short-term construction and development mortgage loans, or (c) invest in long-term mortgages or mortgage pools, and (ii) issuers whose products and services are related to the real estate industry, such as manufacturers and distributors of building supplies and financial institutions that issue or service mortgages.
The Fund may also invest in debt securities of domestic and foreign issuers (including corporate debt obligations and commercial mortgage-backed securities). The Fund may invest up to 10% of its net assets in non-investment grade debt securities (commonly known as “junk bonds”) of real estate and real estate-related issuers.
Under normal circumstances, the Fund will provide exposure to investments that are economically tied to at least three different countries, including the U.S and at least 40%, unless market conditions are not deemed favorable, in which case at least 30% of the Fund’s net assets will provide exposure to investments that are economically tied to countries other than the U.S. The Fund may invest up to 20% of its net assets in securities of issuers located in emerging market countries, i.e., those that are generally in the early stages of their industrial cycles.
The Fund may invest in securities of issuers of all capitalization sizes. Real estate companies tend to have smaller asset bases compared with other market sectors, therefore, the Fund may hold a significant amount of securities of small- and mid-capitalization issuers.
The Fund may engage in short sales of securities. The Fund may engage in short sales with respect to securities it owns or securities it does not own. Generally, the Fund will sell a security short to (1) take advantage of an expected decline in the security price in anticipation of purchasing the same security at a later date at a lower price, or (2) to protect a profit in a security that it owns. The Fund will not sell a security short if, as a result of such short sale, the aggregate market value of all securities sold short exceeds 10% of the Fund’s net assets.
The Fund can invest in derivative instruments including forward foreign currency contracts.
The Fund can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated; though the Fund has not historically used these instruments.
When constructing the portfolio, the portfolio managers use a fundamentals-driven investment process, including an evaluation of factors such as property market cycle analysis, property evaluation and management and structure review to identify securities with characteristics including (i) quality underlying properties, (ii) solid management teams with the ability to effectively manage capital structure decisions and execute their stated strategic plan, and (iii) attractive valuations relative to peer investment alternatives.
The portfolio managers focus on equity REITs and real estate operating issuers. Each qualified security in the investment universe is analyzed using fundamental real estate analysis and valuation review to identify securities that appear to have relatively favorable long-term prospects and attractive values. Some of the fundamental real estate factors that are considered include: forecasted occupancy and rental rates of the various property
markets in which a firm may operate, property locations, physical attributes, management depth and skill, insider ownership, overall debt levels, percentage of variable rate financing and fixed charge coverage ratios. The issuers that are believed to have the most attractive fundamental real estate attributes are then evaluated on the basis of relative value. Some of the valuation factors that are considered include: cash flow consistency and growth, dividend yield, dividend coverage and growth, and cash flow and assets to price multiples.
The portfolio managers seek to construct a portfolio with risk characteristics similar to the FTSE EPRA Nareit Developed Index. The Fund uses this index as a guide in structuring the portfolio, but the Fund is not an index fund.
The portfolio managers seek to limit risk through various controls, such as diversifying the portfolio property types and geographic areas as well as by considering the relative liquidity of each security and limiting the size of any one holding.
The portfolio managers will consider selling a security if they conclude (1) its relative valuation has fallen below desired levels, (2) its risk/return profile has changed significantly, (3) its fundamentals have changed, or (4) a more attractive investment opportunity is identified.
In attempting to meet its investment objective or to manage subscription and redemption requests, the Fund may engage in active and frequent trading of portfolio securities.

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 Series I shares of the Fund from year to year as of December 31. The performance table compares the Fund's performance to that of a style-specific benchmark and a broad-based securities market benchmark (in that order). 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 past performance 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.
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).
Updated performance information is available on the Fund’s website at www.invesco.com/us.

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. 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 the 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 the Fund will rise in value.

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 the Fund, the 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.

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
Foreign Securities Risk. The 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 the 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 the 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 the 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.
INVESCO V.I. Global Real Estate Fund | INVESCO V.I. Global Real Estate Fund | Emerging Market Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
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 the 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.
The Fund's investments in China A-shares are subject to trading restrictions, quota limitations and clearing and settlement risks.

Risk [Text Block] oef_RiskTextBlock
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.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Convertible Securities Risk. The market values of convertible securities are affected by market interest rates, the risk of actual issuer default on interest or principal payments and the value of the underlying common stock into which the convertible security may be converted. Additionally, a convertible security is subject to the same types of market and issuer risks that apply to the underlying common stock. In addition, certain convertible securities are subject to involuntary conversions and may undergo principal write-downs upon the occurrence of certain triggering events, and, as a result, are subject to an increased risk of loss. Convertible securities may be rated below investment grade and therefore considered to have more speculative characteristics and greater susceptibility to default or decline in market value than investment grade securities.

Risk [Text Block] oef_RiskTextBlock
Geographic Focus Risk. The Fund may from time to time have a substantial amount of its assets invested in securities of issuers located in a single country or a limited number of countries. Adverse economic, political or social conditions in those countries may therefore have a significant negative impact on the Fund’s investment performance.
INVESCO V.I. Global Real Estate Fund | INVESCO V.I. Global Real Estate Fund | Small- and Mid-Capitalization Companies Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
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 the 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 V.I. Global Real Estate Fund | INVESCO V.I. Global Real Estate 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 the 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 the 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 the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The 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. The credit analysis applied to the 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.

Risk [Text Block] oef_RiskTextBlock
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 the 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.
INVESCO V.I. Global Real Estate Fund | INVESCO V.I. Global Real Estate 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, including collateralized debt obligations and collateralized mortgage obligations, 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 the Fund reinvesting these early payments at lower interest rates, thereby reducing the 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 the Fund’s share price to fall. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of mortgage-backed securities and could result in losses to the Fund. Privately-issued mortgage-backed securities and asset-backed securities may be less liquid than other types of securities and the Fund may be unable to sell these securities at the time or price it desires. During periods of market stress or high redemptions, the 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. The 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.
INVESCO V.I. Global Real Estate Fund | INVESCO V.I. Global Real Estate 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 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 V.I. Global Real Estate Fund | INVESCO V.I. Global Real Estate Fund | Short Position Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Short Position Risk. Because the Fund’s potential loss on a short position arises from increases in the value of the asset sold short, the 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 the 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, the Fund’s short positions will cause the Fund to underperform the overall market and its peers that do not engage in shorting. If the 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 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 the Fund’s returns.

Management Risk. The Fund is actively managed and depends heavily on the Adviser’s or Sub-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. There can be no guarantee that the Adviser’s or Sub-Adviser's investment techniques or investment decisions will produce the desired results. 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.
