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 and may result in higher taxes when Fund shares are held in a taxable account. 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 79% 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. 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 borrowings for investment purposes) in a diversified portfolio of fixed income securities of any maturity and duration. The fixed income securities in which the Fund may invest include corporate bonds, U.S. government securities, mortgage- and asset-backed securities, and bank loans.The Fund primarily invests in investment grade securities but may also invest up to 35% of its total assets in below investment grade securities (commonly known as “high yield securities” or “junk bonds”).The Fund may invest up to 30% of its total assets in foreign fixed income securities, including emerging markets securities, and the Fund may invest without limitation in obligations of supranational entities (e.g., the World Bank). The Fund may enter into forward roll obligations on U.S. government securities, including mortgage dollar rolls and to-be-announced (“TBA”) securities. The Fund may also invest in derivatives, including but not limited to currency forwards and futures contracts on U.S. Treasury 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 ECM and one sub-adviser: Loomis, Sayles & Company, L.P. (the “Sub-Adviser” or “Loomis Sayles”).ECM invests primarily in securities issued or guaranteed by the U.S. government or its agencies or instrumentalities. ECM combines a “top-down” or macroeconomic analysis of the fixed income markets together with “bottom-up” security-by-security fundamental research to identify relative value opportunities.Loomis Sayles invests in fixed income securities that it believes are attractively valued based on the credit outlook of an issuer and maximum total return potential. Loomis Sayles takes environmental, social and governance (“ESG”) factors into consideration as part of its credit research analysis. If the impact of these factors is found to be financially material in nature, it may affect Loomis Sayles’ decision to buy or sell an issuer. ESG considerations are only one component in the evaluation of eligible investments and may not be a determinative factor in the final investment decision.ECM maintains a strategic allocation of the Fund’s assets with the Sub-Adviser and reviews the asset allocations on a quarterly basis, or more frequently as deemed necessary. As of the date of this Prospectus, the target asset allocation is a 50% allocation of the Fund’s assets to ECM and a 50% allocation of the Fund’s assets to Loomis Sayles. Actual allocations may vary from the target allocations and ECM may change the asset allocations at any time without shareholder notice or approval.

Empower Core Strategies Flexible Bond Fund | Interest Rate Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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 the Fund’s investments, including negatively affecting yield, value and/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, which could, in turn, negatively impact the Fund’s performance.
Empower Core Strategies Flexible Bond Fund | Credit Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Credit Risk - An issuer (or guarantor) of a security may default on its obligations to pay principal and/or interest. A security’s value may be affected by changes in its credit quality rating or its issuer’s financial conditions.
Empower Core Strategies Flexible Bond 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 Core Strategies Flexible Bond Fund | Mortgage Backed Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Mortgage-Backed Securities Risk - Mortgage-backed securities represent interests in pools of commercial or residential mortgages that are subject to the risk that borrowers will prepay the principal on their loans more quickly than expected (prepayment risk) when mortgage rates fall or more slowly than expected (extension risk) when mortgage rates rise, which may affect the yield, average life and price of the securities. Because of prepayment risk and extension risk, mortgage-backed securities react differently to changes in interest rates than other fixed income securities. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities.
Empower Core Strategies Flexible Bond Fund | Liquidity Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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. Extraordinary and sudden changes in interest rates could disrupt the market for fixed income securities and result in fluctuations in the Fund’s net asset value. Increased redemptions due to a rise in interest rates may require the Fund to liquidate its holdings at an unfavorable time and/or under adverse or disadvantageous conditions which may negatively affect the Fund. Investments in many, but not all, 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.
Empower Core Strategies Flexible Bond Fund | Call Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Call Risk - An issuer may redeem a fixed income security before maturity (a “call”) at a price below its current market value.
Empower Core Strategies Flexible Bond 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 on U.S. Treasury securities, 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 Core Strategies Flexible Bond Fund | US Government Sponsored Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock U.S. Government-Sponsored Securities Risk - Securities issued by U.S. government-sponsored enterprises (“GSEs”), such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association and the Federal Home Loan Banks, may be adversely affected by changes in interest rates (interest rate risk) or a default by or decline in the credit rating of the applicable GSE (credit risk). Securities of GSEs are not issued or guaranteed by the U.S. Treasury and are not backed by the full faith and credit of the U.S. government.
Empower Core Strategies Flexible Bond Fund | US Government Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock U.S. Government Securities Risk - U.S. government securities may be adversely affected by changes in interest rates (interest rate risk) or a default by or decline in the credit rating of the U.S. government (credit risk).
Empower Core Strategies Flexible Bond Fund | Below Investment Grade Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Below Investment Grade Securities Risk - Below investment grade securities (commonly known as “high yield securities” or “junk bonds”) are speculative, have a higher degree of credit risk and interest rate risk, and may be less liquid and subject to greater volatility in market value than investment grade securities. In addition, high yield securities present a greater risk of loss (which may be substantial or total) of income and principal, than investment grade securities.
Empower Core Strategies Flexible Bond Fund | Asset Backed Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Asset-Backed Securities Risk - Asset-backed securities represent interests in pools of assets, including consumer loans, auto loans, student loans, or receivables held in trust. The value of asset-backed securities may be affected by certain factors such as interest rate risk; the credit performance of the pool of underlying assets; the creditworthiness of the servicing agent or the originator of the underlying assets; the ability of the servicing agent to service the underlying collateral; and the availability of information concerning the pool of underlying assets and its structure. Asset-backed securities are also subject to the risk that borrowers will prepay the principal on their loans more quickly than expected (prepayment risk) in a declining interest rate environment or more slowly than expected (extension risk) in a rising interest rate environment.
Empower Core Strategies Flexible Bond Fund | To Be Announced Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock To-Be-Announced Securities Risk - TBA securities involve the risk that a security the Fund buys will lose value prior to its delivery. There is also the risk that the security will not be issued or that the other party to the transaction will not meet its obligations. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.
Empower Core Strategies Flexible Bond Fund | Mortgage Dollar Roll Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Mortgage Dollar Roll Risk - Mortgage dollar roll transactions involve the risk that the market value of the securities sold by the Fund may decline below the repurchase price of those securities. Since the counterparty in the transaction is required to deliver a similar, but not identical, security to the Fund, the security the Fund is required to buy under the mortgage dollar roll may be worth less than an identical security. These transactions involve the risk that the portfolio managers may not correctly predict mortgage prepayments and interest rates, which may diminish the Fund’s performance. In addition, investment in mortgage dollar rolls may increase the Fund’s portfolio turnover rate, which can increase the Fund’s expenses and decrease returns. There is no assurance that the Fund’s use of cash it receives from a mortgage dollar roll will provide a return that exceeds borrowing costs.
Empower Core Strategies Flexible Bond 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 Core Strategies Flexible Bond Fund | Emerging Markets Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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 and 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, or from 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 negative 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.
Empower Core Strategies Flexible Bond 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 Core Strategies Flexible Bond Fund | Bank Loan Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Bank Loan Risk - Bank loans often involve borrowers whose financial conditions are troubled or uncertain and companies that are highly leveraged. The market for bank loans may not be highly liquid and the Fund may have difficulty selling bank loans. These investments expose the Fund to the credit risk of both the financial institution and the underlying borrower.
Empower Core Strategies Flexible Bond 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 Core Strategies Flexible Bond 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 Core Strategies Flexible Bond Fund | Multi Manager Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Multi-Manager Risk - Because the Adviser and Sub-Adviser make investment decisions independently, it is possible that the security selection processes of the Adviser and Sub-Adviser may not complement one another, and the Fund may have buy and sell transactions in the same security on the same day.
Empower Core Strategies Flexible Bond 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) and may result in higher taxes when Fund shares are held in a taxable account.

[1] The investment adviser has contractually agreed to waive management fees or reimburse expenses if Total Annual Fund Operating Expenses of any Class exceed 0.45% 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.
