Empower Core Strategies International Equity Fund Investment Risks - Empower Core Strategies International Equity Fund
Dec. 31, 2025
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity Securities Risk - The value of equity securities held by the 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 the Fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting (or perceived to affect) specific issuers held by the Fund, particular industries represented in the Fund’s portfolio, or the overall securities markets. A variety of factors can increase the volatility of the 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.
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 the Fund.
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 the Fund to lose money on investments denominated in foreign currencies.
Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Sector Risk - The Fund may invest a significant portion of its assets in companies within a particular sector, and its performance may suffer if that sector underperforms the overall market.
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 the Fund focuses its investments may cause the value of its shares to decrease, perhaps significantly.
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.
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.
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.
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 the 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 the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Liquidity Risk - The 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. Liquidity risk may also refer to the risk that the 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. 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.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk - The use of derivatives, including but not limited to futures contracts and forward foreign currency contracts, may expose the 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 the Fund’s other portfolio holdings, magnified losses resulting from leverage, counterparty risk, high price volatility, liquidity risk, segregation risk, valuation risk and legal restrictions.
Index Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Index Risk - Because the Keyridge sub-advised portion of the Fund is not actively managed but is designed to track the performance of the MSCI EAFE Index, investors should generally expect the value of the Keyridge sub-advised portion of the Fund to decline when the performance of the MSCI EAFE Index declines. There is no guarantee that the Fund will achieve a high degree of correlation to the MSCI EAFE Index. Additionally, the MSCI EAFE Index may perform unfavorably or underperform the market as a whole. As a result, the Keyridge sub-advised portion of the Fund may have poor investment results even if it closely tracks the performance of the MSCI EAFE Index because the adverse performance of a particular security normally will not result in eliminating the security from the Keyridge sub-advised portion of the Fund.
Tracking Error Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Tracking Error Risk - The Keyridge sub-advised portion of the Fund may not be able to precisely track the performance of the MSCI EAFE Index. Unlike the Keyridge sub-advised portion of the Fund, the performance of the MSCI EAFE Index is not impacted by fees and expenses, including trading costs associated with implementing portfolio changes. In addition, the Keyridge sub-advised portion of the Fund may own less than all the securities of the MSCI EAFE Index, which also may cause a variance between the performance of the Keyridge sub-advised portion of the Fund and the performance of the MSCI EAFE Index. Tracking error risk may cause the Keyridge sub-advised portion of the Fund’s performance to be less than expected.
Quantitative Model Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Quantitative Model Risk - Securities selected by LSV using a quantitative investment model can perform differently than the market as a whole based on the factors used in the model, the weight placed on each factor, and changes in the factors’ historical trends. Due to the significant role technology plays in a quantitative investment model, its use carries the risk of potential issues with the design, coding, implementation or maintenance of the computer programs, data, or technology used in the model. There can be no assurance that the use of a quantitative investment model will enable the Fund to achieve its objective.
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, the Fund could underperform in comparison to other funds with similar objectives and investment strategies and may generate losses even in a favorable market.
Multi Manager Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Multi-Manager Risk - Because the Sub-Advisers make investment decisions independently, it is possible that their security selection processes may not complement one another, and the Fund may have buy and sell transactions in the same security on the same day.
Depositary Receipts Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Depositary Receipts Risk - Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, political and economic risk, and market risk, because their values depend on the performance of a foreign security denominated in its home currency.
Exchange Traded Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Exchange-Traded Fund Risk - Shares in an ETF represent an interest in a portfolio of securities generally designed to track the performance of a particular market index. The Fund could purchase shares issued by an ETF to temporarily gain exposure to a portion of a foreign market, for example, while awaiting purchase of underlying securities. The risks associated with owning an ETF generally reflect the risks of owning the underlying securities it is designed to track, although ETFs have management fees that increase their costs. Fund shareholders indirectly bear their proportionate share of the expenses of the ETFs in which the Fund invests. An ETF may trade at a premium or discount, and, as a result, the Fund may pay more than net asset value when purchasing shares and receive less than net asset value when selling shares.
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 is not a deposit with a bank, is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any government agency
