Objective [Heading]	rr_ObjectiveHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Investment Objective</span>
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	Falling U.S. Dollar ProFund (the “Fund”) seeks daily investment results, before fees and expenses, that correspond to the daily performance of the basket of non-U.S. currencies included in the ICE® U.S. Dollar Index® (the “Index”). The Index measures the value of the U.S. Dollar against a basket of currencies of the top six trading partners of the United States, as measured in 1973 (the “Benchmark”). These currencies and their weightings as of July 31, 2023 are: euro 57.6%; Japanese yen 13.6%; British pound 11.9%; Canadian dollar 9.1%; Swedish krona 4.2% and Swiss franc 3.6%. The Fund is designed to benefit from a decline in the value of the U.S. Dollar against the value of the currencies included in the Benchmark. Accordingly, as the value of the U.S. Dollar depreciates (i.e., “falls”) versus the Benchmark, the performance of the Fund generally should be expected to increase. As the value of the U.S. Dollar appreciates versus the Benchmark, the performance of the Fund generally should be expected to decline.

Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The table below describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Portfolio Turnover</span>
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 may indicate higher transaction costs and may result in higher taxes when the Fund’s shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the example above, affect the Fund’s performance. During the most recent fiscal year, the Fund’s annual portfolio turnover rate was 0% of the average value of its portfolio. This portfolio turnover rate is calculated without regard to cash instruments or derivatives transactions. If such transactions were included, the Fund’s portfolio turnover rate would be significantly higher.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem or hold all of your shares at the end of each period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the fee waiver/expense reimbursement is assumed only to pertain to the first year. Although your actual costs may be higher or lower, based on these assumptions your approximate costs would be:

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests in financial instruments that ProFund Advisors believes, in combination, should track the performance of the Index.The Index is calculated and maintained by ICE Data Indices, LLC. The Index measures the value of the U.S. Dollar against a basket of currencies of the top six trading partners of the United States as measured in 1973. More information about the Index is published under the Bloomberg ticker symbol “DXY.”Under normal circumstances, the Fund will invest at least 80% of its total assets in component securities of the Index or in instruments with similar economic characteristics.The Fund will invest principally in the financial instruments listed below.•Derivatives — Financial instruments whose value is derived from the value of an underlying asset or assets, such as stocks, bonds, ETFs, interest rates or indexes. The Fund invests in derivatives in order to gain exposure to the Index. These derivatives principally include:○Forward Contracts — Two-party contracts where a purchase or sale of a specific quantity of a commodity, security, foreign currency or other financial instrument is entered into with dealers or financial institutions at a set price, with delivery and settlement at a specified future date. Forward contracts may also be structured for cash settlement, rather than physical delivery.•Money Market Instruments — The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:○U.S. Treasury Bills — U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.○Repurchase Agreements — Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.ProFund Advisors uses a mathematical approach to investing in which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce returns consistent with its investment objective. The Fund seeks to remain fully invested at all times in financial instruments that, in combination, provide exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining exposure consistent with the investment objective.Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.

Falling US Dollar ProFund | Risk Nondiversified Status [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Non-Diversification Risk — The Fund has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty.
Falling US Dollar ProFund | Derivatives Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Risks Associated with the Use of Derivatives — Investing in derivatives to obtain exposure may be considered aggressive and may expose the Fund to greater risks including counterparty risk and correlation risk. The Fund may lose money if its derivatives do not perform as expected. Any costs associated with using derivatives will reduce the Fund’s return.
Falling US Dollar ProFund | Counterparty Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Counterparty Risk — The Fund may lose money if a counterparty does not meet its contractual obligations.
Falling US Dollar ProFund | Correlation Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Correlation Risk — A number of factors may affect the Fund’s ability to achieve a high degree of correlation with the Index. Fees, expenses, transaction costs, among other factors, will adversely impact the Fund’s ability to meet its investment objective. In addition, the Fund’s exposure may not be consistent with the Index. For example, the Fund may not have exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index.
Falling US Dollar ProFund | Foreign Currency Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Foreign Currency Risk — Investments linked to or denominated in foreign currencies are exposed to additional risk factors versus those investments denominated in U.S. dollars and linked to U.S. investments. The value of an investment linked to or denominated in a foreign currency could change significantly as foreign currencies strengthen or weaken relative to the U.S. dollar. Devaluations of a currency by a government or banking authority may also have significant impact on the value of any investments linked to or denominated in that currency. Risks related to foreign currencies also include those related to economic or political developments, market inefficiencies or a higher risk that essential investment information may be incomplete, unavailable, or inaccurate. Foreign currency losses could offset or exceed any potential gains, or add to losses, in the related investments. Currency markets are also generally not as regulated as securities markets.
Falling US Dollar ProFund | Money Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Money Market Instruments Risk — Adverse economic, political or market events affecting issuers of money market instruments, defaults by counterparties or changes in government regulations may have a negative impact on the performance of the Fund.
Falling US Dollar ProFund | Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Market Risk — The Fund is subject to market risks that will affect the value of its shares, including adverse issuer, political, regulatory, market or economic developments, as well as developments that impact specific economic sectors, industries or segments of the market.
Falling US Dollar ProFund | Geographic Concentration Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Geographic Concentration Risk — Because the Fund focuses its investments in one or more foreign countries, an investment in the Fund may be more volatile than a more geographically diversified fund. The performance of the Fund will be affected by the political, social and economic conditions in those foreign countries and subject to the related risks.
Falling US Dollar ProFund | Index Performance Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Index Performance Risk — The Index used by the Fund may underperform other asset classes and may underperform other similar indices. The Index is maintained by a third party provider unaffiliated with the Fund or ProFund Advisors. There can be no guarantee that the methodology underlying the Index or the daily calculation of the Index will be free from error.
Falling US Dollar ProFund | Active Investor Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Active Investor Risk —The Fund permits short-term trading of its securities. This may have a negative impact on the Fund’s ability to achieve its investment objective or maintain a consistent level of operating expenses. In certain circumstances, the Fund’s expense ratio may vary from current estimates or the historical ratio disclosed in this Prospectus.
Falling US Dollar ProFund | Early Close Late Close Trading Halt Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	•Early Close/Late Close/Trading Halt Risk — An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments.
