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 2% 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 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 Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Below is a summary of the principal investment strategies of the Fund.The Fund is not actively managed but is designed to track the performance of its Benchmark Index. The Fund will, under normal circumstances, invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in common stocks of the companies included in the Benchmark Index. The Benchmark Index is designed to measure the performance of 500 of the top companies in leading industries of the U.S. economy and represents the large cap segment of the U.S. equities market.The Fund uses the replication method of indexing, meaning the Fund seeks to own the securities contained in the Benchmark Index in as close as possible a proportion of the Fund as each stock’s weight in the Benchmark Index. The Fund may focus its investments in certain sectors, such as the technology sector. The Fund may also invest in derivatives, including but not limited to futures contracts on the Benchmark Index and options on futures contracts.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 Irish Life Investment Managers Limited (the “Sub-Adviser” or “ILIM”).

Empower SP 500 Index 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 SP 500 Index 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 SP 500 Index Fund | Large Size Company Risk [Member] |
|
|
Risk Return Abstract |
rr_RiskReturnAbstract |
|
Risk [Text Block] |
rr_RiskTextBlock |
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.
|
Empower SP 500 Index Fund | Sector Risk [Member] |
|
|
Risk Return Abstract |
rr_RiskReturnAbstract |
|
Risk [Text Block] |
rr_RiskTextBlock |
Sector Risk - The Fund may, from time to time, 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.
|
Empower SP 500 Index 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 the Benchmark Index and options on 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 SP 500 Index Fund | Index Risk [Member] |
|
|
Risk Return Abstract |
rr_RiskReturnAbstract |
|
Risk [Text Block] |
rr_RiskTextBlock |
Index Risk - Because the Fund is not actively managed but is designed to track the performance of the Benchmark Index, investors should generally expect the value of the Fund to decline when the performance of the Benchmark Index declines. There is no guarantee that the Fund will achieve a high degree of correlation to the Benchmark Index. Additionally, the Benchmark Index may perform unfavorably and/or underperform the market as a whole. As a result, the Fund may have poor investment results even if it closely tracks the performance of the Benchmark Index because the adverse performance of a particular security normally will not result in eliminating the security from the Fund.
|
Empower SP 500 Index Fund | Tracking Error Risk [Member] |
|
|
Risk Return Abstract |
rr_RiskReturnAbstract |
|
Risk [Text Block] |
rr_RiskTextBlock |
Tracking Error Risk - The Fund may not be able to precisely track the performance of the Benchmark Index. Unlike the Fund, the performance of the Benchmark Index is not impacted by fees and expenses, including trading costs associated with implementing portfolio changes. In addition, the Fund may own less than all the securities of the Benchmark Index, which also may cause a variance between the performance of the Fund and the performance of the Benchmark Index. Tracking error risk may cause the Fund’s performance to be less than expected.
|
Empower SP 500 Index 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.
