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 generally indicates 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 turnover rate was 211% of the average value of its portfolio.

The Example does not reflect the fees and expenses of any Permitted Account. If the fees and expenses of any Permitted Account were reflected, the fees and expenses in the Example 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 each period. The Example also assumes that the Expense Limit is in place for the first year, that your investment has a 5% return each year, that all dividends and capital gains are reinvested, and that the Fund’s operating expenses are the amount shown in the fee table and remain the same for the years shown. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Strategy [Heading] rr_StrategyHeading <span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;">Principal Investment Strategies</span>
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock Below is a summary of the principal investment strategies of the Fund.The Fund will, under normal circumstances, invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities of U.S. mid-capitalization (“mid cap”) companies, including foreign issuers that are traded in the U.S. For purposes of the 80% policy, the Fund considers mid cap companies to be those whose market capitalization falls within the range of the Russell Midcap® Value Index at the time of initial purchase. As of December 31, 2024, the market capitalization range of the Russell Midcap® Value Index was between $205 million and $69.7 billion. If the market capitalization of a company held by the Fund moves outside this range, the Fund may, but is not required to, sell the securities. The Fund emphasizes a “value style” of investing, seeking companies that are undervalued in comparison to their peers due to economic, market, company-specific or other factors, but have the prospect of achieving improved valuations in the future. The Fund may invest in real estate investment trusts (“REITs”) and derivatives, including but not limited to futures contracts. The Fund may engage in active and frequent trading of its portfolio securities. Empower Capital Management, LLC (“ECM”) is the Fund’s investment adviser and, subject to the approval of the Board of Directors of Empower Funds (the “Board”), selects the Fund’s sub-adviser and monitors its performance on an ongoing basis. The Fund’s investment portfolio is managed by Goldman Sachs Asset Management, L.P. (the “Sub-Adviser” or “GSAM”). GSAM manages the Fund using a quantitative investment process, in combination with a qualitative overlay. GSAM’s investment style emphasizes fundamentally based stock selection, careful portfolio construction and efficient implementation. As a part of GSAM's investment selection process, GSAM utilizes proprietary models that assess a wide range of indicators, which may include certain environmental, social and governance (“ESG”) indicators. ESG considerations are only one component in the evaluation of eligible investments and may not be a determinative factor in the final investment decision.

Empower Mid Cap Value Fund | Equity Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
Empower Mid Cap Value Fund | Market Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
Empower Mid Cap Value Fund | Small Or Mid Cap Company Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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 and tend to be more volatile and less liquid than stocks of larger companies, especially over the short term, and are more likely not 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.
Empower Mid Cap Value Fund | Value Stock Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
Empower Mid Cap Value Fund | Real Estate Investment Trust Real Estate Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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, among others: 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 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.
Empower Mid Cap Value Fund | Quantitative Model Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Quantitative Model Risk - Securities selected by the Sub-Adviser 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 and/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.
Empower Mid Cap Value Fund | Foreign Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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 other similar measures may also impair the value or liquidity of affected securities and negatively impact the Fund.
Empower Mid Cap Value Fund | Currency Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
Empower Mid Cap Value Fund | Derivatives Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk - The use of derivatives, including but not limited to futures 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.
Empower Mid Cap Value Fund | Management Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
Empower Mid Cap Value Fund | Environmental Social and Governance Considerations Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Environmental, Social and Governance Considerations Risk - The Fund’s portfolio selection strategy is not solely based on ESG considerations, and therefore the issuers in which the Fund invests may not be considered ESG-focused companies. Consideration of ESG factors may affect the Fund’s exposure to certain issuers or industries and may not work as intended. While ESG considerations may have the potential to contribute to the Fund’s long-term performance, there is no guarantee that such results will be achieved.
Empower Mid Cap Value Fund | Portfolio Turnover Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Portfolio Turnover Risk - High portfolio turnover rates generally result in higher transaction costs (which are borne directly by the Fund and indirectly by shareholders).

[1] The investment adviser has contractually agreed to waive management fees or reimburse expenses if Total Annual Fund Operating Expenses of any Class exceed 0.70% of the Class's average daily net assets, excluding Distribution and Service (12b-1) Fees, Shareholder Services Fees, brokerage expenses, taxes, dividend interest on short sales, interest expenses, and any extraordinary expenses, including litigation costs (the “Expense Limit”). The agreement’s current term ends on April 30, 2026, and automatically renews for one-year terms unless it is terminated upon termination of the investment advisory agreement or by Empower Funds or the investment adviser upon written notice within 90 days of the end of the current term. Under the agreement, the investment adviser may recoup, subject to the approval of the Board of Directors of Empower Funds, these waivers and reimbursements in future periods, not exceeding three years following the particular waiver/reimbursement, provided Total Annual Fund Operating Expenses of the Class plus such recoupment do not exceed the lesser of the Expense Limit that was in place at the time of the waiver/reimbursement or the Expense Limit in place at the time of recoupment.
