| 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 fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During its most recent fiscal year, the fund’s portfolio turnover rate was 46% of the average value of its portfolio. | ||||||||

The example assumes a 5% average annual return and that fund expenses will not change over the periods. 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:Arial Narrow;font-size:10pt;font-weight:bold;">Principal investment strategies</span> | ||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in companies with market capitalizations that are within the S&P Mid Cap 400 Index ($1.6 billion to $26.8 billion as of October 31, 2024) or the Russell Midcap Value Index ($150 million to $65 billion as of October 31, 2024). The fund invests in a diversified mix of common stocks of mid-size U.S. companies that are believed to be undervalued by various measures and offer good prospects for capital appreciation. The manager employs a value approach in selecting investments. The manager’s in-house research team seeks to identify companies whose stock prices do not appear to reflect their underlying values. The manager generally looks for companies with one or more of the following characteristics: ●Low stock prices relative to net assets, earnings, cash flow, sales, book value, or private market value; ●Demonstrated or potentially attractive operating margins, profits and/or cash flow; ●Sound balance sheets and other positive financial characteristics; ●Stock ownership by management/employees; and ●Experienced and capable management. The fund’s sector exposure is broadly diversified as a result of stock selection and therefore may vary significantly from its benchmark, the Russell Midcap Value Index. The market capitalization of companies held by the fund and included in the indices changes over time. The fund will not automatically sell or cease to purchase stock of a company it already owns just because the company’s market capitalization grows or falls outside these ranges. The fund may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities. In pursuing the fund’s investment objective, the manager has the discretion to deviate from its normal investment criteria, as described above, and purchase securities that the manager believes will provide an opportunity for substantial appreciation. These situations might arise when the manager believes a security could increase in value for a variety of reasons, including a change in management, an extraordinary corporate event, a new product introduction or innovation, or a favorable competitive development. The fund may invest in initial public offerings (IPOs). While most assets will be invested in U.S. common stocks, the fund may purchase other types of securities, for example: convertible securities and warrants, foreign securities (up to 20% of total assets), certain exchange-traded funds (ETFs), and certain derivatives (investments whose value is based on indices or other securities). For purposes of the fund, ETFs are considered securities with a market capitalization equal to the weighted average market capitalization of the basket of securities comprising the ETF. The fund holds a certain portion of its assets in money market reserves which can consist of shares of the T. Rowe Price Government Reserve Fund (or any other internal T. Rowe Price money market fund) as well as money market securities, including repurchase agreements, in the two highest rating categories, maturing in one year or less. The fund may invest up to 10% of its total assets in hybrid instruments. Hybrid instruments are a type of high-risk derivative which can combine the characteristics of securities, futures and options. Such securities may bear interest or pay dividends at below (or even relatively nominal) rates. Except when engaged in temporary defensive investing, the fund normally has less than 10% of its assets in cash and cash equivalents. The fund may focus its investments in a particular sector or sectors of the economy. | ||||||||

| Risk [Text Block] | rr_RiskTextBlock | An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | ||||||||
| Class NAV | Mid Value Fund | Convertible Securities Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Convertible securities risk. Convertible securities are subject to certain risks of both equity and debt securities. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. As the market price of underlying common stock declines below the conversion price, the market value of the convertible security tends to be increasingly influenced by its yield. | ||||||||
| Class NAV | Mid Value Fund | Credit And Counterparty Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Credit and counterparty risk. The counterparty to an over-the-counter derivatives contract or a borrower of fund securities may not make timely payments or otherwise honor its obligations. | ||||||||
| Class NAV | Mid Value Fund | Economic And Market Events Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate. | ||||||||
| Class NAV | Mid Value Fund | Equity Securities Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Equity securities risk. The price of equity securities may decline due to changes in a company’s financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole. | ||||||||
| Class NAV | Mid Value Fund | Exchange Traded Funds Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Exchange-traded funds (ETFs) risk. The risks of owning shares of an ETF include the risks of owning the underlying securities the ETF holds. Lack of liquidity in an ETF could result in the ETF being more volatile than its underlying securities. An ETF’s shares could trade at a significant premium or discount to its net asset value (NAV). A fund bears ETF fees and expenses indirectly. | ||||||||
| Class NAV | Mid Value Fund | Foreign Securities Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign securities risk. Less information may be publicly available regarding foreign issuers, including foreign government issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. | ||||||||
| Class NAV | Mid Value Fund | Hedging Derivatives And Other Strategic Transactions Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase a fund’s volatility and could produce disproportionate losses, potentially more than the fund’s principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Derivatives and other strategic transactions that the fund intends to utilize include: futures contracts and options. Futures contracts and options generally are subject to counterparty risk. | ||||||||
| Class NAV | Mid Value Fund | Hybrid instrument risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Hybrid instrument risk. Hybrid instruments (a type of potentially high-risk derivative) combine the elements of futures contracts or options with those of debt, preferred equity or a depository instrument. Hybrid instruments entail greater market risk and may be more volatile than traditional debt instruments, may bear interest or pay preferred dividends at below-market rates, and may be illiquid. The risks of investing in hybrid instruments are a combination of the risks of investing in securities, options, futures, and currencies. | ||||||||
| Class NAV | Mid Value Fund | Initial Public Offerings Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Initial public offerings (IPOs) risk. IPO share prices are frequently volatile and may significantly impact fund performance. | ||||||||
| Class NAV | Mid Value Fund | Investment company securities risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investment company securities risk. Fund shareholders indirectly bear their proportionate share of the expenses of any investment company in which the fund invests. The total return on such investments will be reduced by the operating expenses and fees of such other investment companies, including advisory fees. | ||||||||
| Class NAV | Mid Value Fund | Liquidity Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. | ||||||||
| Class NAV | Mid Value Fund | Operational And Cybersecurity Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Operational and cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund’s securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes. | ||||||||
| Class NAV | Mid Value Fund | Repurchase Agreement Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Repurchase agreements risk. The risk of a repurchase agreement transaction is limited to the ability of the seller to pay the agreed-upon sum on the delivery date. In the event of bankruptcy or other default by the seller, the instrument purchased may decline in value, interest payable on the instrument may be lost and there may be possible difficulties and delays in obtaining collateral and delays and expense in liquidating the instrument. | ||||||||
| Class NAV | Mid Value Fund | Sector Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Sector risk. When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. | ||||||||
| Class NAV | Mid Value Fund | Small And Mid Sized Company Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Small and mid-sized company risk. Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole. | ||||||||
| Class NAV | Mid Value Fund | Value Investment Style Risk [Member] | ||||||||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Value investment style risk. Value securities may underperform the market as a whole, which may cause value-oriented funds to underperform equity funds with other investment strategies. Securities the manager believes are undervalued may never perform as expected. | ||||||||
