| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies with large market capitalizations at the time of purchase that, in the opinion of Principal Global Investors, LLC ("PGI"), the Fund's investment advisor, display characteristics of a "blue chip" company. For this Fund, companies with large market capitalizations are those with market capitalizations similar to companies in the Russell 1000 Growth Index ("Index"). Performance benefited from selection in financials, consumer discretionary, industrials and communication services. Amazon was the Fund’s largest contributor. Both retail and cloud business Amazon Web Services performed well last year. The next largest contributor was Netflix. The company’s free cashflow growth pushed its flywheel to profitably reinvest in its business and attract more subscribers. The third largest contributor was Alphabet. The company’s efficiency efforts had a positive impact on financial results. Company selection in information technology, real estate and healthcare detracted from performance. Having a smaller weight in Nvidia than its weight in the Index, detracted on a relative basis. Commercial real estate data and analytics business CoStar detracted. CoStar’s two main businesses (CoStar Suite and apartments.com) are doing well. They are investing in a third business, that shows promise but has not yet been monetized. Animal Health business Zoetis detracted from performance. The pet industry in general has not yet normalized following the pandemic bump, resulting in less visits to the veterinarian. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide current income. Under normal circumstances, the Fund uses a passive investment approach known as "sampling" to invest at least 80% of its net assets, plus any borrowings for investment purposes, in investments designed to track the Bloomberg U.S. Aggregate Bond Index ("Index") at the time of purchase. The Index is composed of investment grade, fixed rate debt issues with maturities of one year or more, including government securities, corporate securities, and asset-backed and mortgage-backed securities (securitized products). During the 12 months ending December 31, 2024, the Fund’s investments underperformed the Index. Top contributors to performance included a slightly lower allocation compared to Index weight to government related credit, security specific impacts within U.S. Treasury securities, and security specific impacts within sovereign bonds. Primary detractors to performance included a slightly lower allocation compared to Index weight to commercial mortgage-backed securities, security specific impacts within mortgage-backed securities, and security specific impacts within investment grade corporate bonds. | |

Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in bonds or other debt securities at the time of purchase. Such investments include securities issued or guaranteed by the U.S. government or its agencies or instrumentalities; asset-backed securities and mortgage-backed securities (securitized products, including collateralized mortgage obligations); corporate bonds; and foreign securities, including emerging market securities. During the past year, the top contributing factors included an out-of-index allocation to below investment grade corporate bonds, security selection within investment grade corporate bonds, and curve positioning.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide as high a level of total return (consisting of reinvested income and capital appreciation) as is consistent with reasonable risk. The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes. It generally allocates approximately 50% of its assets to equity index underlying funds to gain broad market capitalization exposure to both U.S. and non-U.S. investments, including investments in smaller companies, and approximately 50% to fixed-income index underlying funds for intermediate duration fixed-income exposure. Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged. Within U.S. equities, large-cap equities achieved the strongest earnings growth and outperformed mid- and small-cap equities. The strong risk-on rally in U.S. equities and the higher for longer interest rate environment weighed on U.S. core fixed income which still posted a slightly positive return for the year. | |

The largest component of the blended benchmark is included to show how the Fund’s performance compares with returns of indices of funds with similar investment objectives. The weightings of the Diversified Balanced Custom Index are as follows: 50% Bloomberg U.S. Aggregate Bond Index, 35% S&P 500 Index, 7% MSCI EAFE Index NTR, 4% S&P MidCap 400 Index, and 4% S&P SmallCap 600 Index. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide as high a level of total return (consisting of reinvested income and capital appreciation) as is consistent with reasonable risk. The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes. It generally allocates approximately 50% of its assets to equity index underlying funds to gain broad market capitalization exposure to both U.S. and non-U.S. investments, including investments in smaller companies, and approximately 50% to fixed-income index underlying funds for intermediate duration fixed-income exposure. Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged. Within U.S. equities, large-cap equities achieved the strongest earnings growth and outperformed mid- and small-cap equities. The strong risk-on rally in U.S. equities and the higher for longer interest rate environment weighed on U.S. core fixed income which still posted a slightly positive return for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide as high a level of total return (consisting of reinvested income and capital appreciation) as is consistent with reasonable risk, while seeking to control volatility. The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes (collectively, the "underlying funds"). The Fund also invests in cash and cash equivalents (as investments and/or to serve as margin or collateral for derivatives positions) and derivative instruments (primarily exchange-traded futures). Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged. Within U.S. equities, large-cap equities achieved the strongest earnings growth and outperformed mid- and small-cap equities. The strong risk-on rally in U.S. equities and the higher for longer interest rate environment weighed on U.S. core fixed income which still posted a slightly positive return for the year. The Fund may utilize futures to manage equity exposures, reducing risk and volatility profiles as dictated by market conditions and proprietary volatility signals. | |

The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes (collectively, the "underlying funds"). It generally allocates approximately 50% of its assets to equity index underlying funds to gain broad market capitalization exposure to both U.S. and non-U.S. investments and approximately 50% to fixed-income index underlying funds for intermediate duration fixed-income exposure. Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide as high a level of total return as is consistent with reasonable risk, with an emphasis on managing volatility. The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes (collectively, the "underlying funds"). It generally allocates approximately 50% of its assets to equity index underlying funds to gain broad market capitalization exposure to both U.S. and non-U.S. investments and approximately 50% to fixed-income index underlying funds for intermediate duration fixed-income exposure. Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged. Within U.S. equities, large-cap equities achieved the strongest earnings growth and outperformed mid- and small-cap equities. The strong risk-on rally in U.S. equities and the higher for longer interest rate environment weighed on U.S. core fixed income which still posted a slightly positive return for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide long-term capital appreciation. The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes (collectively, the "underlying funds"). It generally allocates approximately 65% of its assets to equity index underlying funds to gain broad market capitalization exposure to both U.S. and non-U.S. investments and approximately 35% to fixed-income index underlying funds for intermediate duration fixed-income exposure. Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged. Within U.S. equities, large-cap equities achieved the strongest earnings growth and outperformed mid- and small-cap equities. The strong risk-on rally in U.S. equities and the higher for longer interest rate environment weighed on U.S. core fixed income which still posted a slightly positive return for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide long-term capital appreciation, while seeking to control volatility. The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes (collectively, the "underlying funds"). It also invests in cash and cash equivalents (as investments and/or to serve as margin or collateral for derivatives positions) and derivative instruments (primarily exchange-traded futures). Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged. Within U.S. equities, large-cap equities achieved the strongest earnings growth and outperformed mid- and small-cap equities. The strong risk-on rally in U.S. equities and the higher for longer interest rate environment weighed on U.S. core fixed income which still posted a slightly positive return for the year. The Fund may utilize futures to manage equity exposures, reducing risk and volatility profiles as dictated by market conditions and proprietary volatility signals. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide long-term capital appreciation, with an emphasis on managing volatility. The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes (collectively, the "underlying funds"). It generally allocates approximately 65% of its assets to equity index underlying funds to gain broad market capitalization exposure to both U.S. and non-U.S. investments and approximately 35% to fixed-income index underlying funds for intermediate duration fixed-income exposure. Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged. Within U.S. equities, large-cap equities achieved the strongest earnings growth and outperformed mid- and small-cap equities. The strong risk-on rally in U.S. equities and the higher for longer interest rate environment weighed on U.S. core fixed income which still posted a slightly positive return for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide a high level of total return (consisting of reinvestment of income with some capital appreciation). The Fund operates as a fund of funds and invests in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, Inc., Principal Exchange-Traded Funds, and other fund complexes (collectively, the "underlying funds"). The Fund generally allocates approximately 35% of its assets to equity index underlying funds to gain broad market capitalization exposure to both U.S. and non-U.S. investments and approximately 65% to fixed-income index underlying funds for intermediate duration fixed-income exposure. Global equity markets posted positive returns in 2024 with U.S. equities significantly outperforming developed-ex U.S. equities. U.S. equities benefited from above trend economic strength, upheld by strong consumers and robust corporate balance sheets, while non-U.S. developed market economic growth lagged. Within U.S. equities, large-cap equities achieved the strongest earnings growth and outperformed mid- and small-cap equities. The strong risk-on rally in U.S. equities and the higher for longer interest rate environment weighed on U.S. core fixed income which still posted a slightly positive return for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks long-term growth of capital. The Fund invests primarily in foreign equity securities. It has no limitation on the percentage of assets that are invested in any one country or denominated in any one currency, but the Fund typically invests in foreign securities of at least 20 countries. Primary consideration is given to securities of issuers of developed areas (for example, Japan, Western Europe, Canada, Australia, Hong Kong, and Singapore); however, the fund also invests in emerging market securities. The Fund invests in equity securities regardless of market capitalization size and style (growth or value). The financials and consumer staples sectors had strong stock selection leading to outperformance relative to the MSCI All Country Ex U.S. Index. 3i Group and Tencent were top contributors. 3i, a global leader in private equity, has benefited from sales growth at their discount retailer Action. Tencent, a Chinese digital platform, benefited from strong online advertisement revenue. On the other hand, negative attribution was seen in the information technology and industrials sectors. Samsung Electronics and Localiza Rent a Car were the top detractors. Samsung Electronics, a South Korean conglomerate with a focus on memory chips, traded lower as investors wait for the high bandwidth memory chip qualification from NVIDIA. However, the current valuation makes Samsung appealing as we move into 2025. Localiza Rent a Car, a Brazilian car rental company, traded lower on a reduction in rental utilization from a weakening macroeconomic environment in Brazil. However, the company has long term growth potential in an underpenetrated market. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide current income and long-term growth of income and capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in dividend-paying equity securities at the time of purchase. It usually invests in equity securities of companies with large and medium market capitalizations. The Fund invests in value equity securities, an investment strategy that emphasizes buying equity securities that appear to be undervalued. KKR & Co (KKR) contributed to results because its growth in profits and alternative assets fundraising surpassed investor expectations. Taiwan Semiconductor Manufacturing (TSM) contributed to relative results to the Russell 1000 Value Index ("Index") as the company’s revenues and margins topped expectations fueled by demand for their AI chips. Not owning Intel (INTC) contributed to performance as CEO, Pat Gelsinger retired after failing to turn around the company and posting a $16 billion net loss in October. Magna (MGA) detracted from result as the company lowered sales guidance primarily due to a large customer, Fisker Ocean, ceasing production. Not owning Walmart (WMT) detracted from performance.

The Russell 1000 Value Index is included as an additional index for the Fund as it shows how the Fund’s performance compares with the returns of an index of funds with similar investment objectives. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide current income and long-term growth of income and capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in dividend-paying equity securities at the time of purchase. It usually invests in equity securities of companies with large and medium market capitalizations. The Fund invests in value equity securities, an investment strategy that emphasizes buying equity securities that appear to be undervalued. KKR & Co (KKR) contributed to results because its growth in profits and alternative assets fundraising surpassed investor expectations. Taiwan Semiconductor Manufacturing (TSM) contributed to relative results to the Russell 1000 Value Index ("Index") as the company’s revenues and margins topped expectations fueled by demand for their AI chips. Not owning Intel (INTC) contributed to performance as CEO, Pat Gelsinger retired after failing to turn around the company and posting a $16 billion net loss in October. Magna (MGA) detracted from result as the company lowered sales guidance primarily due to a large customer, Fisker Ocean, ceasing production. Not owning Walmart (WMT) detracted from performance.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide current income and long-term growth of income and capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in dividend-paying equity securities at the time of purchase. It usually invests in equity securities of companies with large and medium market capitalizations. The Fund invests in value equity securities, an investment strategy that emphasizes buying equity securities that appear to be undervalued. KKR & Co (KKR) contributed to results because its growth in profits and alternative assets fundraising surpassed investor expectations. Taiwan Semiconductor Manufacturing (TSM) contributed to relative results to the Russell 1000 Value Index ("Index") as the company’s revenues and margins topped expectations fueled by demand for their AI chips. Not owning Intel (INTC) contributed to performance as CEO, Pat Gelsinger retired after failing to turn around the company and posting a $16 billion net loss in October. Magna (MGA) detracted from result as the company lowered sales guidance primarily due to a large customer, Fisker Ocean, ceasing production. Not owning Walmart (WMT) detracted from performance.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks long-term growth of capital. The Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of emerging market companies at the time of purchase. The Fund considers a security to be tied economically to an emerging market if the issuer of the security has its principal place of business or principal office in an emerging market, has its principal securities trading market in an emerging market, or derives a majority of its revenue from emerging markets. During the year the Fund's investments performed in-line with the MSCI Emerging Markets Index ("Index"). The Asia ex-China region was the top relative performer to the Index, led by Taiwan and South Korea. Outperformance in Taiwan came from positive stock selection in the information technology sector, led by our semiconductor related holdings. Gains in South Korea came from the industrials sector where the Fund’s investment in a defense company outperformed. Brazil was the other notable contributor, led by gains in the financials and materials sectors. The Fund benefitted from an underweight position to financials and no exposure to Vale in the materials sector. EMEA was the worst performing region. The Fund was hurt by underweight positions to United Arab Emirates and Turkey, up 19.6% and 17.8%, respectively. The Fund also had negative performance in Saudi Arabia, led by negative stock selection in the energy and financials sectors. Latin America was another source of weakness during the last year entirely driven by Mexico. The Fund was hurt by the overweight position to the market and negative stock selection in the materials sector. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide a high level of current income consistent with safety and liquidity. The Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in debt securities issued by the U.S. government, its agencies or instrumentalities or debt securities that are rated, at the time of purchase, AAA by S&P Global Ratings or Aaa by Moody's. It maintains an average portfolio duration that is within 50% of the duration of the Bloomberg U.S. Agency Fixed-Rate MBS Index ("Index"). Fundamentals remained favorable for the mortgage-backed securities (MBS) market for the majority of 2024. The technical environment improved in 2024. Money managers maintained a strong bid for MBS and generally held overweight MBS allocations throughout the year. Year over year the Index spreads moved from 47 basis points ("bps") to 43bps. Current coupon spreads to UST 5/10 year performed similarly moving from 139bps to 135bps year over year. Coupon allocation contributed to performance for the year as the Fund maintained an overweight position to the higher coupons in the Index (i.e. Conventional/Ginnie Mae 5%-6%). The Fund's curve position also contributed to performance as the yield curve steepened over the course of year. The Fund’s relative duration versus the Index detracted from performance for the year as the Fund was generally positioned longer than the Index. The Fund's underweight position to the 15-year portion of the Index also detracted from performance. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies with large market capitalizations at the time of purchase. For this Fund, companies with large market capitalizations are those with market capitalizations within the range of companies comprising the Russell 1000 Growth Index ("Index"). The Fund is non-diversified. For the year, T. Rowe Price Associates, Inc. (T. Rowe) and Brown Advisory, LLC’s (Brown) underperformed the Index. T. Rowe’s performance benefited from strong stock selection in the health care sector and an underweight to the consumer staples and industrials sectors. Brown’s performance benefited from strong stock selection within the consumer staples and industrials sectors, as well as an underweight to the materials sector. Brown underperformed the Index due to poor stock selection within the information technology sector, as well as an overweight to the industrials and health care sectors. T. Rowe underperformed the Index due to poor stock selection in the information technology and consumer staples sectors, as well as an overweight to the health care sector. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies that compose the S&P 500 Index ("Index") at the time of purchase. The Index is designed to represent U.S. equities with risk/return characteristics of the large cap universe. During the 12 months ending in December 2024, the Fund's investments were in line with the Index. The Fund uses an indexing strategy and does not attempt to manage market volatility, use defensive strategies or reduce the effect of any long-term periods of negative stock market performance. Ten of the eleven economic sectors in the Index posted positive returns for the year with the communication services and information technology sectors providing the best return. The materials and healthcare sectors recorded the worst returns. NVIDIA, Broadcom, and Meta Platforms contributed to Fund performance. Super Micro Computer, Intel, and CVS Health detracted from Fund performance for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies that compose the S&P 500 Index ("Index") at the time of purchase. The Index is designed to represent U.S. equities with risk/return characteristics of the large cap universe. During the 12 months ending in December 2024, the Fund's investments were in line with the Index. The Fund uses an indexing strategy and does not attempt to manage market volatility, use defensive strategies or reduce the effect of any long-term periods of negative stock market performance. Ten of the eleven economic sectors in the Index posted positive returns for the year with the communication services and information technology sectors providing the best return. The materials and healthcare sectors recorded the worst returns. NVIDIA, Broadcom, and Meta Platforms contributed to Fund performance. Super Micro Computer, Intel, and CVS Health detracted from Fund performance for the year. | |

Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies with medium market capitalizations at the time of purchase. For this Fund, companies with medium market capitalizations are those with market capitalizations within the range of companies comprising the Russell Midcap Index ("Index"). Over the last 12 months, the Fund benefited most from selection in financials, its heaviest weighted sector. Alternative asset managers KKR & Co, Inc. and Brookfield Corporation were two top contributors. Both companies grew assets under management, reported good investment performance and accelerated asset monetization. Aerospace components supplier TransDigm was the next top contributor. TransDigm’s founder attributed its success to having a simple and focused strategy. Selection in materials companies and allocation in health care contributed to performance relative to the Index. Commercial real estate data and analytics business CoStar detracted. CoStar’s two main businesses (CoStar Suite and apartments.com) are doing well. They are investing in a third business, that shows promise but has not yet been monetized. Selection in technology detracted. Microchip is in the midst of an inventory correction and Verisign saw temporary weakness in Internet domain name registrations due to a regulatory change in China. | |

The Russell MidCap Index is included as an additional index for the Fund as it shows how the Fund’s performance compares with the returns of an index of funds with similar investment objectives. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide long-term growth of capital. The Fund invests primarily in equity securities of companies with any market capitalization, but it has a greater exposure to large market capitalization companies than small or medium market capitalization companies. Those managing the Fund's investments seek to invest in securities of businesses that they believe are trading at a discount to their private market value (i.e., the value of the business if it was sold), have a competitive advantage, and/or that have barriers to entry in their respective industries. Owning Broadcom Inc. (AVGO) aided results as the company benefitted from an AI-driven rally along with other chip makers. GE Vernova (GEV) contributed to results as the company revised guidance higher and noted production slots for heavy-duty gas turbines are almost sold out through 2028. Constellation Energy (CEG) reported stronger than expected guidance for revenue growth and earnings. Adobe Inc. (ADBE) issued a weak fourth quarter guide and detracted from relative performance to the Russell 3000 Index. Ulta Beauty (ULTA) detracted from performance as investors worried about increased competition. Lam Research Corporation (LRCX) detracted from results as investors worried about a weak NAND recovery and lower exposure to leading-edge chips. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide long-term growth of capital. The Fund invests primarily in equity securities of companies with any market capitalization, but it has a greater exposure to large market capitalization companies than small or medium market capitalization companies. Those managing the Fund's investments seek to invest in securities of businesses that they believe are trading at a discount to their private market value (i.e., the value of the business if it was sold), have a competitive advantage, and/or that have barriers to entry in their respective industries. Owning Broadcom Inc. (AVGO) aided results as the company benefitted from an AI-driven rally along with other chip makers. GE Vernova (GEV) contributed to results as the company revised guidance higher and noted production slots for heavy-duty gas turbines are almost sold out through 2028. Constellation Energy (CEG) reported stronger than expected guidance for revenue growth and earnings. Adobe Inc. (ADBE) issued a weak fourth quarter guide and detracted from relative performance to the Russell 3000 Index. Ulta Beauty (ULTA) detracted from performance as investors worried about increased competition. Lam Research Corporation (LRCX) detracted from results as investors worried about a weak NAND recovery and lower exposure to leading-edge chips. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks a total return consisting of long-term growth of capital and current income. The Fund operates as a "target date fund" that invests according to an asset allocation strategy designed for investors having a retirement investment goal close to the year in the Fund's name. The Fund's asset allocation will become more conservative over time as investment goals near (for example, retirement, which is assumed to begin at age 65) and investors become more risk-averse. The Fund is a fund of funds and invests in underlying funds of Principal Funds, Inc. ("PFI") and of Principal Variable Contracts Funds, Inc. ("PVC"). Asset class positioning was the largest positive contributor for the year driven by an overweight to U.S. equity and an underweight to fixed income and non-U.S. equity relative to the S&P Target Date indices. An overweight to high yield bonds across the series contributed positively to performance for the year. The Equity Income, LargeCap Value III, MidCap, and Core Fixed Income investment options outperformed their respective indices for the year. The utilization of diversified non-U.S. equity strategies relative to the developed non-U.S. equity exposure of the S&P Target Date indices, provided for a positive style selection effect. Active management within the U.S. equity asset class was the largest detractor from performance for the year driven mainly by underperformance of the Blue Chip and LargeCap Growth I investment options. Active management within the non-U.S. equity asset class also detracted for the year. An overweight to U.S. midcap and smallcap equities relative to the S&P Target Date indices detracted from performance for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks a total return consisting of long-term growth of capital and current income. The Fund operates as a "target date fund" that invests according to an asset allocation strategy designed for investors having a retirement investment goal close to the year in the Fund's name. The Fund's asset allocation will become more conservative over time as investment goals near (for example, retirement, which is assumed to begin at age 65) and investors become more risk-averse. The Fund is a fund of funds and invests in underlying funds of Principal Funds, Inc. ("PFI") and of Principal Variable Contracts Funds, Inc. ("PVC"). Asset class positioning was the largest positive contributor for the year driven by an overweight to U.S. equity and an underweight to fixed income and non-U.S. equity relative to the S&P Target Date indices. An overweight to high yield bonds across the series contributed positively to performance for the year. The Equity Income, LargeCap Value III, MidCap, and Core Fixed Income investment options outperformed their respective indices for the year. The utilization of diversified non-U.S. equity strategies relative to the developed non-U.S. equity exposure of the S&P Target Date indices, provided for a positive style selection effect. Active management within the U.S. equity asset class was the largest detractor from performance for the year driven mainly by underperformance of the Blue Chip and LargeCap Growth I investment options. Active management within the non-U.S. equity asset class also detracted for the year. An overweight to U.S. midcap and smallcap equities relative to the S&P Target Date indices detracted from performance for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks a total return consisting of long-term growth of capital and current income. The Fund operates as a "target date fund" that invests according to an asset allocation strategy designed for investors having a retirement investment goal close to the year in the Fund's name. The Fund's asset allocation will become more conservative over time as investment goals near (for example, retirement, which is assumed to begin at age 65) and investors become more risk-averse. The Fund is a fund of funds and invests in underlying funds of Principal Funds, Inc. ("PFI") and of Principal Variable Contracts Funds, Inc. ("PVC"). Asset class positioning was the largest positive contributor for the year driven by an overweight to U.S. equity and an underweight to fixed income and non-U.S. equity relative to the S&P Target Date indices. An overweight to high yield bonds across the series contributed positively to performance for the year. The Equity Income, LargeCap Value III, MidCap, and Core Fixed Income investment options outperformed their respective indices for the year. The utilization of diversified non-U.S. equity strategies relative to the developed non-U.S. equity exposure of the S&P Target Date indices, provided for a positive style selection effect. Active management within the U.S. equity asset class was the largest detractor from performance for the year driven mainly by underperformance of the Blue Chip and LargeCap Growth I investment options. Active management within the non-U.S. equity asset class also detracted for the year.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks a total return consisting of long-term growth of capital and current income. The Fund operates as a "target date fund" that invests according to an asset allocation strategy designed for investors having a retirement investment goal close to the year in the Fund's name. The Fund's asset allocation will become more conservative over time as investment goals near (for example, retirement, which is assumed to begin at age 65) and investors become more risk-averse. The Fund is a fund of funds and invests in underlying funds of Principal Funds, Inc. ("PFI") and of Principal Variable Contracts Funds, Inc. ("PVC"). Asset class positioning was the largest positive contributor for the year driven by an overweight to U.S. equity and an underweight to fixed income and non-U.S. equity relative to the S&P Target Date indices. An overweight to high yield bonds across the series contributed positively to performance for the year. The Equity Income, LargeCap Value III, MidCap, and Core Fixed Income investment options outperformed their respective indices for the year. The utilization of diversified non-U.S. equity strategies relative to the developed non-U.S. equity exposure of the S&P Target Date indices, provided for a positive style selection effect. Active management within the U.S. equity asset class was the largest detractor from performance for the year driven mainly by underperformance of the Blue Chip and LargeCap Growth I investment options. Active management within the non-U.S. equity asset class also detracted for the year.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks current income, and as a secondary objective, capital appreciation. The Fund's asset allocation is designed for investors who are approximately 10 years beyond the normal retirement age of 65. The Fund is a fund of funds and invests in underlying funds of Principal Funds, Inc. ("PFI") and of Principal Variable Contracts Funds, Inc. ("PVC"). Asset class positioning was the largest positive contributor for the year driven by an overweight to U.S. equity and an underweight to fixed income and non-U.S. equity relative to the S&P Target Date Index Retirement Income Index ("Index"). An overweight to high yield and short-term bonds also contributed positively to performance year. The Equity Income, LargeCap Value III, MidCap, and Core Fixed Income investment options outperformed their respective indices for the year. The utilization of diversified non-U.S. equity strategies relative to the developed non-U.S. equity exposure of the Index, provided for a positive style selection effect. Active management within the U.S. equity asset class was the largest detractor from performance for the year driven mainly by underperformance of the Blue Chip and LargeCap Growth I investment options. Active management within the non-U.S. equity asset class also detracted for the year.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to generate a total return. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies principally engaged in the real estate industry at the time of purchase. A real estate company has at least 50% of its assets, income or profits derived from products or services related to the real estate industry. It is non-diversified. The Fund's investments outperformed the FTSE NAREIT All Equity REIT Index and underperformed the MSCI US REIT Index net of fees during the year. An overweight to U.S. senior housing REITs remained the key contributor, with these REITs demonstrating continued strong earnings growth and guidance upgrades on firming occupancy, improving pricing power and accretive acquisitions. The underweight to land and timber was also additive as higher for longer interest rates delayed the recovery in housing market transaction volumes which are an important demand driver for timber stocks. Detraction came from the underweight to a document storage REIT that is in process of pivoting its business to data centers.

The FTSE NAREIT All Equity REIT Index is included as an additional index for the Fund as it shows how the Fund’s performance compares with returns of an index of funds with similar investment objectives. Prior to March 1, 2024, the Fund’s index was the MSCI US REIT Index. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to generate a total return. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies principally engaged in the real estate industry at the time of purchase. A real estate company has at least 50% of its assets, income or profits derived from products or services related to the real estate industry. It is non-diversified. The Fund's investments outperformed the FTSE NAREIT All Equity REIT Index and underperformed the MSCI US REIT Index net of fees during the year. An overweight to U.S. senior housing REITs remained the key contributor, with these REITs demonstrating continued strong earnings growth and guidance upgrades on firming occupancy, improving pricing power and accretive acquisitions. The underweight to land and timber was also additive as higher for longer interest rates delayed the recovery in housing market transaction volumes which are an important demand driver for timber stocks. Detraction came from the underweight to a document storage REIT that is in process of pivoting its business to data centers. The underweight to the cyclical malls sector also hurt as these stocks rallied on signs of resilient economic growth. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide as high a level of total return (consisting of reinvested income and capital appreciation) as is consistent with reasonable risk. The Fund operates as a fund of funds and invests principally in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, and Principal Exchange-Traded Funds. It generally invests between 40% and 80% of its assets in equity funds, and less than 30% in any one equity fund. The Fund's allocation in U.S. large cap growth equities, which outperformed their value counterparts, was the largest positive contributor to performance for the year. In addition, relative to the blended benchmark, the Fund's allocation of overweight to equity, underweight to fixed income, and overweight to alternative & specialty securities aided performance for the year. Lastly, the Fund's allocation in U.S. mega cap equities, which outperformed their large cap counterparts, positively contributed to performance for the year. Security selection in U.S. large cap growth equities was the largest detractor to performance for the year. In addition, the Fund's allocation in developed ex.-U.S. equities, which underperformed their emerging market counterparts, hindered performance for the year.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide as high a level of total return (consisting of reinvested income and capital appreciation) as is consistent with reasonable risk. The Fund operates as a fund of funds and invests principally in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, and Principal Exchange-Traded Funds. It generally invests between 40% and 80% of its assets in equity funds, and less than 30% in any one equity fund. The Fund's allocation in U.S. large cap growth equities, which outperformed their value counterparts, was the largest positive contributor to performance for the year. In addition, relative to the blended benchmark, the Fund's allocation of overweight to equity, underweight to fixed income, and overweight to alternative & specialty securities aided performance for the year. Lastly, the Fund's allocation in U.S. mega cap equities, which outperformed their large cap counterparts, positively contributed to performance for the year. Security selection in U.S. large cap growth equities was the largest detractor to performance for the year. In addition, the Fund's allocation in developed ex.-U.S. equities, which underperformed their emerging market counterparts, hindered performance for the year. Lastly, the Fund's allocation in U.S. large cap value equities, which underperformed their growth counterparts, negatively contributed to performance for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide a high level of total return (consisting of reinvestment of income and capital appreciation), consistent with a moderate degree of principal risk. The Fund operates as a fund of funds and invests principally in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, and Principal Exchange-Traded Funds. It generally invests between 40% and 80% of its assets in fixed-income funds, and less than 40% in any one fixed-income fund. The Fund generally invests between 20% and 60% of its assets in equity funds, and less than 30% in any one equity fund. It generally invests less than 20% of its assets in specialty funds, and less than 20% in any one specialty fund. The Fund's allocation in U.S. large cap growth equities, which outperformed their value counterparts, was the largest positive contributor to performance for the year. In addition, the Fund's allocation in U.S. mega cap equities, which outperformed their large cap counterparts, aided performance for the year. Lastly, the Fund's allocation to preferred securities, which outperformed core fixed income, positively contributed to performance for the year. Security selection in U.S. large cap growth equities was the largest detractor to performance for the year. In addition, the Fund's allocation in developed ex.-U.S. equities, which underperformed their emerging market counterparts, hindered performance for the year. Lastly, the Fund's allocation in U.S. large cap value equities, which underperformed their growth counterparts, negatively contributed to performance for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide long-term capital appreciation. The Fund operates as a fund of funds and invests principally in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, and Principal Exchange-Traded Funds. It generally invests between 0% and 40% of its assets in fixed-income funds, and less than 30% in any one fixed-income fund. The Fund generally invests between 60% and 100% of its assets in equity funds, and less than 40% in any one equity fund. It generally invests less than 20% of its assets in specialty funds, and less than 20% in any one specialty fund. The Fund's allocation in U.S. large cap growth equities, which outperformed their value counterparts, was the largest positive contributor to performance for the year. In addition, the Fund's allocation in U.S. mega cap equities, which outperformed their large cap counterparts, aided performance for the year. Lastly, security selection in U.S. mega cap equities positively contributed to performance for the year. Security selection in U.S. large cap growth equities was the largest detractor to performance for the year. In addition, the Fund's allocation in developed ex.-U.S. equities, which underperformed their emerging market counterparts, hindered performance for the year. Lastly, the Fund's allocation in U.S. large cap value equities, which underperformed their growth counterparts, negatively contributed to performance for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide a high level of total return (consisting of reinvestment of income with some capital appreciation). The Fund operates as a fund of funds and invests principally in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, and Principal Exchange-Traded Funds. It generally invests between 55% and 95% of its assets in fixed-income funds, and less than 40% in any one fixed-income fund. The Fund generally invests between 5% and 45% of its assets in equity funds, and less than 30% in any one equity fund. It generally invests less than 20% of its assets in specialty funds, and less than 20% in any one specialty fund. The Fund's allocation to preferred securities, which outperformed core fixed income, was the largest positive contributor to performance for the year.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide a high level of total return (consisting of reinvestment of income with some capital appreciation). The Fund operates as a fund of funds and invests principally in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, and Principal Exchange-Traded Funds. It generally invests between 55% and 95% of its assets in fixed-income funds, and less than 40% in any one fixed-income fund. The Fund generally invests between 5% and 45% of its assets in equity funds, and less than 30% in any one equity fund. It generally invests less than 20% of its assets in specialty funds, and less than 20% in any one specialty fund. The Fund's allocation to preferred securities, which outperformed core fixed income, was the largest positive contributor to performance for the year. In addition, the Fund's allocation in U.S. mega cap equities, which outperformed their large cap counterparts, aided performance for the year. Lastly, security selection in U.S. mega cap equities positively contributed to performance for the year. The Fund's allocation in developed ex.-U.S. equities, which underperformed their emerging market counterparts, was the largest detractor to performance for the year. In addition, the Fund's allocation in U.S. large cap value equities, which underperformed their growth counterparts, hindered performance for the year. Lastly, the Fund's allocation in U.S. mid cap equities, which underperformed their large cap counterparts, negatively contributed to performance for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide long-term capital appreciation. The Fund operates as a fund of funds and invests principally in funds and exchange-traded funds ("ETFs") of Principal Funds, Inc., Principal Variable Contracts Funds, and Principal Exchange-Traded Funds. It generally invests between 75% and 100% of its assets in equity funds, and less than 50% in any one equity fund. The Fund invests less than 20% of its assets in specialty funds, and less than 20% in any one specialty fund. The Fund's allocation in U.S. large cap growth equities, which outperformed their value counterparts, was the largest positive contributor to performance for the year. In addition, the Fund's allocation in U.S. mega cap equities, which outperformed their large cap counterparts, aided performance for the year. Lastly, security selection in U.S. mega cap equities positively contributed to performance for the year. Security selection in U.S. large cap growth equities was the largest detractor to performance for the year. In addition, the Fund's allocation in developed ex.-U.S. equities, which underperformed their emerging market counterparts, hindered performance for the year. Lastly, the Fund's allocation in U.S. large cap value equities, which underperformed their growth counterparts, negatively contributed to performance for the year. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide as high a level of current income as is consistent with prudent investment management and stability of principal. The Fund invests primarily in high quality short-term bonds and other fixed-income securities that, at the time of purchase, are rated BBB- or higher by S&P Global Ratings ("S&P Global") or Baa3 or higher by Moody's Investors Service, Inc. ("Moody's") or, if unrated, in the opinion of those selecting such investments, are of comparable quality. It invests in foreign securities. It maintains an effective maturity of five years or less and an average portfolio duration that is within ±30% of the duration of the Bloomberg Credit 1-3 Year Index ("Index"). During the 12 month period ending December 31, 2024 the Fund's investments outperformed the Index. Sector allocation and issuer selection were positive contributors to performance while changes in the yield curve were a drag on performance. Out of index positions in non-agency commercial mortgage-backed securities, student loan asset-backed securities and non-agency residential mortgage-backed securities contributed positively to performance. The Fund also benefitted from issuer selection in the banking, consumer non-cyclical, and technology sectors. An out of index position in U.S. Treasuries was a drag on performance. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies with small market capitalizations at the time of purchase. For this Fund, companies with small market capitalizations are those with market capitalizations within the range of companies comprising the Russell 2000 Index ("Index"). The Fund's investments underperformed the Index during the year. The Fund performed well in the first half of the year amid a market environment where fundamentals were the key driver of stocks. The Fund faced challenges in early July amid renewed optimism around the likelihood of an economic soft-landing and potential rate cuts. The market quickly reversed to being led by smaller less liquid names amid passive exchange-traded funds (ETF) buying in small caps. The Fund also underperformed in early November following the U.S. election results amid a sharp risk on market environment where passive ETF flows were a significant driver of stocks. The Fund continued to recover following the election results as company fundamentals came back into focus, but ultimately the Fund's investments underperformed the Index. Natera, a blood based diagnostic company, was the top contributor to the Fund’s performance as it outperformed amid strength from their innovative products.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies with small market capitalizations at the time of purchase. For this Fund, companies with small market capitalizations are those with market capitalizations within the range of companies comprising the Russell 2000 Index ("Index"). The Fund's investments underperformed the Index during the year. The Fund performed well in the first half of the year amid a market environment where fundamentals were the key driver of stocks. The Fund faced challenges in early July amid renewed optimism around the likelihood of an economic soft-landing and potential rate cuts. The market quickly reversed to being led by smaller less liquid names amid passive exchange-traded funds (ETF) buying in small caps. The Fund also underperformed in early November following the U.S. election results amid a sharp risk on market environment where passive ETF flows were a significant driver of stocks. The Fund continued to recover following the election results as company fundamentals came back into focus, but ultimately the Fund's investments underperformed the Index. Natera, a blood based diagnostic company, was the top contributor to the Fund’s performance as it outperformed amid strength from their innovative products.

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide investors with returns (before fees and expenses) based on the S&P 500 Price Return Index (“Index”), while seeking to provide a buffer against the first 10% (prior to taking into account any fees and expenses of the Fund) of Index losses, over a twelve-month period. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in exchange-traded funds ("ETFs") and options that reference the Index at the time of each purchase. The Principal Variable Contracts U.S. LargeCap Buffer Funds are defined outcome investment solutions that are designed to offer limited downside protection, full upside participation up to 10%, and partial participation on any gains above 10%. The Fund uses a combination of ETFs and options to accomplish this objective. The out-of-the-money put and ETF holdings contributed to performance, while the at-the-money put and out-of-the-money call detracted from performance. Overall, the Fund's investments performance since launch is inline with expectations. Note that intra-period performance may differ in an unpredictable way from full period performance. | |

| Factors Affecting Performance [Text Block] | | Management’s Discussion of Fund Performance The Fund seeks to provide investors with returns (before fees and expenses) based on the S&P 500 Price Return Index ("Index"), while seeking to provide a buffer against the first 10% (prior to taking into account any fees and expenses of the fund) of Index losses, over a twelve-month period. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in exchange-traded funds ("ETFs") and options that reference the Index at the time of each purchase. The Principal Variable Contracts U.S. LargeCap Buffer Funds are defined outcome investment solutions that are designed to offer limited downside protection, full upside participation up to 10%, and partial participation on any gains above 10%. The Fund uses a combination of ETFs and options to accomplish this objective. The out-of-the-money put contributed to performance, while the at-the-money put and out-of-the-money call detracted from performance. Overall, the Fund's investments performance since launch is inline with expectations. Note that intra-period performance may differ in an unpredictable way from full period performance. | |
