| Performance Narrative [Text Block] | The bar chart and table below provide an indication of the risk of investment in the Fund by showing changes in the performance of the Fund’s Investor Class shares for the last ten calendar years and by comparing the Fund’s average annual total returns to the performance of a broad-based securities market index and an additional index with investment characteristics similar to those of the Fund.The returns shown below are historical and are not an indication of future performance.Total return figures assume reinvestment of dividends and capital gains distributions and include the effect of the Fund’s recurring expenses, but do not include the fees and expenses of any Permitted Account. If the fees and expenses of any Permitted Account were reflected, the performance shown would be lower.Updated performance information may be obtained at www.empower.com/investments/empower-funds/fund-documents (the website does not form a part of this Prospectus). |
