Empower Lifetime 2045 Fund Investment Risks - Empower Lifetime 2045 Fund
Dec. 31, 2025
Fund of Funds Structure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Fund-of-Funds Structure Risk•Since the Fund invests directly in the Underlying Funds, all risks associated with the Underlying Funds apply to the Fund. To the extent the Fund invests more of its assets in one Underlying Fund than another, the Fund will have greater exposure to the risks of that Underlying Fund.•Since the Fund invests in Underlying Funds, you will bear your proportionate share of expenses of the Fund and indirectly your proportionate share of expenses of the Underlying Funds. Consequently, an investment in the Fund entails more expenses than a direct investment in the Underlying Funds.
Target Date Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Target Date Fund Risk - The year in the Fund name refers to the approximate year (the target date) when an investor in the Fund is planning to retire (or otherwise begin using the invested funds). The Fund’s asset allocation is adjusted to become more conservative based on its target date. If an investor chooses to retire significantly earlier or later than the target date, a different asset allocation may be more appropriate. An investment in a target date fund is not guaranteed at any time, including on or after the target date. Investors should periodically monitor the portfolio to ensure it is in line with their current situation.
Empower of America Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Empower of America Contract Risk - The Contract has a stable principal value and pays a minimum fixed interest rate to the Fund. Both the principal and interest rate are guaranteed by Empower of America regardless of market conditions. However, if Empower of America were to become insolvent and unable to meet the guarantee, the Fund may lose money from unpaid principal or unpaid or reduced interest, and the Contract would be settled commensurate with other Empower of America policy holder obligations under applicable law.
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity Securities Risk - The value of equity securities held by an Underlying Fund may decline as a result of factors directly related to a company, a particular industry or industries, or general market conditions that are not specifically related to a company or an industry.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk - The value of an Underlying Fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting (or perceived to affect) specific issuers held by an Underlying Fund, particular industries represented in an Underlying Fund’s portfolio, or the overall securities markets. A variety of factors can increase the volatility of an Underlying Fund’s holdings and markets generally, including political or regulatory developments, recessions, inflation, deflation, rapid interest rate changes, bank failures, war or acts of terrorism, sanctions, tariffs, natural disasters, outbreaks of infectious illnesses or other widespread public health issues, general outlook for corporate earnings, or adverse investor sentiment generally. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors and industries more significantly than others. These adverse developments may cause broad declines in an issuer’s value due to short-term market movements or for significantly longer periods during more prolonged market downturns.
Large Size Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Large-Size Company Risk - Large-size companies are generally more mature and may be unable to respond as quickly as smaller companies to new competitive challenges, such as changes in technology and consumer tastes, and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.
Small Or Mid Cap Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Small- and Medium-Size Company Risk - The stocks of small- and medium-size companies often trade in lower volumes, may be less liquid, and are subject to greater or more unpredictable price changes than stocks of larger companies. Such companies may also have limited markets, financial resources or product lines, may lack management depth, and may be more vulnerable to adverse business or market developments. Accordingly, stocks of small- and medium-size companies tend to be more sensitive to changing economic, market, and industry conditions, tend to be more volatile and less liquid than stocks of larger companies, especially over the short term, and are less likely to survive or accomplish their goals, with the result that the value of their stock could decline significantly. In addition, there may be less publicly available information concerning small- and medium-size companies upon which to base an investment decision.
Value Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Value Stock Risk - A value style of investing is subject to the risk that returns on value stocks are less than returns on other styles of investing or the overall stock market. Value stocks tend to trade at lower price-to-book and price-to-earnings ratios, which suggest the market as a whole views their potential future earnings as limited.
Growth Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Growth Stock Risk - A growth style of investing is subject to the risk that returns on growth stocks are less than returns on other styles of investing or the overall stock market. Growth stocks can be volatile for several reasons. Since they usually reinvest a high proportion of earnings in their own business, they may not pay the dividends usually associated with value stocks that can cushion their decline in a falling market. Also, since investors buy these stocks because of the expected superior earnings growth, earnings disappointments may result in sharp price declines.
Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Securities Risk - Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, geopolitical (including war or armed conflict), regulatory, market, currency valuation, or economic or other developments, and can perform differently than the U.S. market. Current tariffs, sanctions, or the threat of potential tariffs, sanctions or similar measures may also impair the value or liquidity of affected securities and negatively impact an Underlying Fund.
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Emerging Markets Risk - Emerging market countries generally have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. The economies of countries with emerging markets may be based predominantly on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from limited reliable access to capital, extreme debt burdens, less established financial market operations or volatile inflation rates. The securities markets of emerging market countries may be subject to manipulation and have historically been extremely volatile and less liquid than more developed markets. These market conditions may continue or worsen. Investments in these countries may be subject to heightened political, geopolitical (including war or armed conflict), economic, legal, market, currency and tariff risks, as well as other adverse local or regional developments, including heightened risk of war and ethnic, religious and racial conflicts. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs), and other government restrictions by the U.S. and other governments, as well as problems in share registration, settlement or custody, may also result in losses. Differences in regulatory, accounting, auditing, and financial reporting and recordkeeping standards could impede the availability of reliable information to evaluate and monitor local companies and impact an Underlying Fund’s performance. There is also the risk of adverse foreign currency exchange 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 Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Currency Risk - Adverse fluctuations in exchange rates between the U.S. dollar and other currencies may cause an Underlying Fund to lose money on investments denominated in foreign currencies.
Geographic Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Geographic Concentration Risk - Events negatively affecting the fiscal stability of a particular country or region in which an Underlying Fund focuses its investments may cause the value of its shares to decrease, perhaps significantly.
Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Fixed Income Securities Risk - Investments in fixed income securities are subject to interest rate risk (the chance that bond prices will decline because of rising interest rates), income risk (the chance that an Underlying Fund’s income will decline because of falling interest rates), credit risk (the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that market perception of the issuer will cause the price of a bond to decline), and call/prepayment risk (the chance that bond issuers will redeem bonds prior to their maturity dates).
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate Risk - The market value of a fixed income security is affected significantly by changes (or the expectation of such changes) in interest rates. A wide variety of market and economic factors can cause interest rates to rise or fall, including central bank monetary policy, rising inflation, disinflation or deflation, and changes in general economic conditions. When interest rates rise, the market value of a fixed income security will generally decline and when interest rates decline, the market values of such securities will generally rise. In general, the longer the maturity or duration of a fixed income security, the greater its sensitivity to changes in interest rates. Changes in interest rates can be difficult to forecast and may have unpredictable effects on the markets and an Underlying Fund’s investments, including negatively affecting yield, value or liquidity. Actions taken by the Federal Reserve Board or foreign central banks to stimulate or stabilize economic growth, such as increases or decreases in short-term interest rates, may adversely affect markets and an Underlying Fund’s performance.
Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit Risk - An issuer (or guarantor) of a security may default on its obligations to pay principal or interest. A security’s value may be affected by changes in its credit quality rating or its issuer’s financial conditions.
Foreign Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Government Securities Risk - Foreign government securities may involve risks similar to those of foreign securities. They also may present additional risks, such as the ability of a foreign government or government-related issuer to make timely principal and interest payments on its external debt obligations.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Liquidity Risk - An Underlying Fund may not be able to sell a security at or near its perceived value in a timely manner (or at all) because of unusual market conditions, an unusually high volume of redemption requests, little or no active trading market for a specific type of security, legal or contractual restrictions on resale, or a reduced number or capacity of market participants to make a market in such security. Securities acquired in a private placement, such as Rule 144A securities, may involve increased liquidity risk due to restrictions on resale and the potential absence of a liquid secondary market or ready purchasers for such securities. Liquidity risk may also refer to the risk that an Underlying Fund will not be able to pay redemption proceeds within the allowable time period or without significant dilution to the remaining investors’ interest due to market conditions or other factors. Extraordinary and sudden changes in interest rates could disrupt the market for fixed income securities and result in fluctuations in an Underlying Fund’s net asset value. Increased redemptions due to a rise in interest rates may require an Underlying Fund to liquidate its holdings at an unfavorable time or under adverse or disadvantageous conditions, which may negatively affect the Underlying Fund. Investments in many foreign securities tend to have greater exposure to liquidity risk than domestic securities because secondary trading markets for these securities may be smaller and less well-developed and the securities may trade less frequently.
Index Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Index Risk - Because an index fund is designed to track the performance of a benchmark index, investors should generally expect the value of the index fund to decline when the performance of its benchmark index declines. As a result, it is possible an index fund could have poor investment results even if it closely tracks the return of its benchmark index, because the adverse performance of a particular security normally will not result in eliminating the security from the fund. It is possible the benchmark index may perform unfavorably and underperform the market as a whole. An index fund is not actively managed and portfolio managers do not attempt to take defensive positions in declining markets. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause an index fund’s return to be lower than if the index fund employed an active strategy.
Real Estate Investment Trust Real Estate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Real Estate Investment Trust/Real Estate Risk - Investments in real estate-related instruments may be affected by similar risks as direct investment in real estate and the real estate market generally, including economic, legal, cultural, governmental, environmental or technological factors that affect property values, rents or occupancies of real estate. Historically, the real estate industry has been cyclical and particularly sensitive to economic downturns and other events that limit demand for real estate, which would adversely impact the value of real estate investments. Real estate companies, including real estate investment trusts (“REITs”) or similar structures, tend to be small and mid cap companies, which means their shares may be more volatile and less liquid. REITs and real estate-related companies may not be diversified due to ownership of a limited number of properties or concentration in a particular geographic region or property type. REITs are also subject to risks associated with changes in interest rates.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk - The use of derivatives, including but not limited to futures contracts, forward contracts, options and swaps, may expose an Underlying Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. These risks include imperfect correlations with underlying investments or an Underlying Fund’s other portfolio holdings, magnified losses resulting from leverage, counterparty risk, high price volatility, liquidity risk, segregation risk, valuation risk and legal restrictions.
Inflation Protected Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Inflation-Protected Securities Risk - The value of inflation-protected securities (“IPS”) generally fluctuates in response to changes in real interest rates, which are in turn tied to the relationship between nominal interest rates and the rate of inflation. If inflation was to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in the value of IPS. In contrast, if nominal interest rates were to increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in the value of IPS. The market for IPS may be less developed or less liquid, and more volatile, than certain other securities markets.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk - A strategy, investment decision, technique, analysis, or model used by the portfolio managers may fail to produce the intended results, or imperfections, errors or limitations in the tools and data used by the portfolio managers may cause unintended results. Therefore, an Underlying Fund could underperform in comparison to other funds with similar objectives and investment strategies and may generate losses even in a favorable market.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] and is subject to the possible loss of your original investment.
Risk Not Insured [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the Fund or Underlying Funds is not a deposit with a bank, is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any government agency
