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 144% of the average value of its portfolio.

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 inflation-protected securities (“IPS”) of varying maturities issued by the U.S. Treasury and other U.S. and non-U.S. government agencies and corporations, and other instruments, including inflation-linked swaps, with similar economic characteristics. Designed to provide inflation protection to investors, IPS are income-generating instruments whose interest and principal payments are periodically adjusted according to the rate of inflation. The Fund may invest in derivatives, including but not limited to exchange-traded futures, interest rate swaps, and inflation-linked swaps that reference the Consumer Price Index For All Urban Consumers (“CPI-U”) as well as other measures of inflation.The remainder of the Fund’s assets may be invested in other fixed income securities, including, corporate bonds, asset-backed securities, mortgage-backed securities, below investment grade securities (commonly known as “high yield securities” or “junk bonds”), securities issued by foreign corporate and governmental issuers and U.S. government securities.The Fund’s target duration range under normal interest rate conditions is expected to approximate that of its benchmark index, the Bloomberg 1-10 Year U.S. Treasury Inflation-Protected Securities Index, plus or minus one year. As of December 31, 2024, the duration of this index was 4.47 years. “Duration” is a measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price will be to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a three-year effective duration will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security’s market price.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 seeks to generate consistent risk-adjusted performance by capitalizing on inefficiencies in markets that cause security prices to diverge from their fair value. GSAM’s fundamental investment process may integrate environmental, social and governance (“ESG”) factors with traditional fundamental factors. 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 Inflation-Protected Securities Fund | Inflation Protected Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Inflation-Protected Securities Risk - The value of 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 liquid, and more volatile, than certain other securities markets.
Empower Inflation-Protected Securities 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 Inflation-Protected Securities Fund | Inflation linked Swaps Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Inflation-linked Swaps Risk - Inflation-linked swaps may expose the Fund to additional volatility in comparison to investing directly in bonds and other fixed income securities. Inflation-linked swaps can be illiquid, difficult to value and may involve leverage so that small changes produce disproportionate losses for the Fund. Since inflation-linked swaps are not traded on an exchange, they are subject to the risk that a counterparty to the transaction will fail to meet its obligations. Inflation-linked swaps involve the risk that the level of inflation and consumer prices will not be accurately predicted, which could significantly harm the Fund’s performance.
Empower Inflation-Protected Securities 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 Inflation-Protected Securities 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 exchange-traded futures, interest rate swaps, and inflation-linked swaps, 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 Inflation-Protected Securities Fund | Counterparty Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Counterparty Risk - A counterparty to a transaction may be unwilling or unable, or perceived (whether by market participants, ratings agencies, pricing services or otherwise) to be unwilling or unable, to make timely interest, principal or settlement payments or otherwise honor its obligations. Counterparty risk may arise because of a counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not.
Empower Inflation-Protected Securities 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 Inflation-Protected Securities Fund | CPIU Measurement Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock CPI-U Measurement Risk - There can be no assurance that the CPI-U, a measurement of changes in the cost of living, will accurately measure the real rate of inflation in the prices of goods and services, which may affect the valuation of the Fund.
Empower Inflation-Protected Securities Fund | Tax Consequences Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Tax Consequences Risk - Adjustments for inflation to the principal amount of an inflation-indexed security may give rise to original issue discount, which will be includable for federal income tax purposes in the Fund’s gross income in the year accrued, even though the Fund will not receive the principal, including any increase thereto, until maturity. As a result, the Fund may be required to make distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so in order to satisfy the distribution requirements for qualifying as a regulated investment company for federal income tax purposes (“regulated investment company”). Also, if the principal value of an inflation-indexed security is adjusted downward due to deflation, amounts previously distributed may be characterized in some circumstances as a return of capital.
Empower Inflation-Protected Securities 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 Inflation-Protected Securities Fund | Deflation Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Deflation Risk - If deflation occurs, the principal and income of IPS held by the Fund would likely decline in price, which could result in losses for the Fund.
Empower Inflation-Protected Securities 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 Inflation-Protected Securities 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 Inflation-Protected Securities 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 Inflation-Protected Securities 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 Inflation-Protected Securities 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 Inflation-Protected Securities 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 Inflation-Protected Securities 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 Inflation-Protected Securities 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 Inflation-Protected Securities Fund | Foreign Government Securities Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock 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.
Empower Inflation-Protected Securities 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 Inflation-Protected Securities 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 0.35% 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.
