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 for Fund shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended December 31, 2024, the Fund’s portfolio turnover rate was 94% of the average value of its portfolio.

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. 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 those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, giving effect to the expense reimbursement agreement described above. Although your

Strategy [Heading] rr_StrategyHeading Investments, Risks, and Performance Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is a diversified fund that, under normal circumstances, invests at least 80% of its net assets in equity securities of companies located in India. The Adviser considers a company or other issuer to be “located” in India, and a security or instrument is deemed to be an Indian security or instrument, if it has substantial ties to India. The Fund currently makes that determination based primarily on one or more of the following criteria with respect to a company or issuer, whether (i) it is organized under the laws of India; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within India; (iii) it has the primary trading markets for its securities in India; (iv) it has its principal place of business in or is otherwise headquartered in India; (v) it is a component of or its issuer is included in the MSCI India Index, the Fund’s primary benchmark index or (vi) it is a governmental entity or an agency, instrumentality or a political subdivision of India. The term “located” and the associated criteria listed above have been defined in such a way that the Fund has latitude in determining whether an issuer should be included within India. The Fund may purchase securities of companies of any market capitalization but expects to emphasize mid and large‑sized companies. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation.
For purposes of maintaining exposure of at least 80% of the Fund’s assets to equity securities of issuers located in India, the Fund may also invest in American Depository Receipts (“ADRs”), Global Depository Receipts (“GDRs”) and other types of depository receipts with respect to issuers located in India. The Fund may also invest in privately placed and restricted securities.
The Fund’s investments are generally traded in currencies other than U.S. dollars, so the Adviser buys and sells foreign currencies to facilitate transactions in portfolio securities. The Adviser usually does not hedge against possible fluctuations in exchange rates, but exposure to a particular currency that the Adviser believes is overvalued may be hedged if the Fund has a substantial position in securities traded in that currency. The Fund may buy and sell currencies for cash at current exchange rates, or using an agreement to purchase or sell a specified currency at a specified future date or within a specified time period, at a price set at the time of the contract.
The investment policy of the Fund relating to the types of securities in which 80% of the Fund’s assets must be invested may be changed by the Fund’s Board of Trustees without shareholder approval upon at least 60 days’ notice.

Baron India Fund | Risk Lose Money [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Fund losses may be incurred due to declines in one or more markets in which Fund investments are made.
Baron India Fund | Risks Associated with India [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Risks Associated with India. Investing in Indian securities may involve additional risks to those inherent in investing in U.S. securities, including exchange rate fluctuations, political or economic instability, the imposition of exchange controls, expropriation, limited disclosure and illiquid markets. Government actions, bureaucratic obstacles and inconsistent economic reform within the Indian government have had a significant effect on the Indian economy and could adversely affect market conditions, economic growth and the profitability of private enterprises in India. Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. Large portions of many Indian companies remain in the hands of their founders (including members of their families). Corporate governance standards of family-controlled companies may be weaker and less transparent, which increases the potential for loss and unequal treatment of investors. Religious, cultural and military disputes persist in India and between India and Pakistan (as well as sectarian groups within each country).
Baron India Fund | Developing Countries [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Developing Countries. India is considered to be a developing country and the value of Indian securities are subject to all of the risks of non‑U.S. investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.
Baron India Fund | Currency [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Currency. The value of foreign currencies in which Fund will invest may decline versus the U.S. dollar, which reduces the dollar value of securities denominated in that currency. The overall impact on the Fund’s holdings can be significant, unpredictable and long-lasting, depending on the currencies represented in the portfolio and how each one appreciates or depreciates in relation to the U.S. dollar and whether currency positions are hedged. Under normal conditions, the Fund does not engage in extensive foreign currency hedging programs. Further, because exchange rate movements are volatile, the Fund’s attempts at hedging could be unsuccessful, and it may not be possible to effectively hedge the currency risks of many developing countries.
Baron India Fund | Geopolitical Events Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Geopolitical Events Risk. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia’s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund’s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. The active and expanding conflict in the Middle East between Israel and Hamas presents considerable market risks. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere.
Baron India Fund | Depository Receipts [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Depository Receipts. Although depository receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depository receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.
Baron India Fund | Growth Investing [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Growth Investing. Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Growth stocks tend to be more expensive relative to their earnings or asset compared to other types of stocks. As a result, because growth stocks tend to be sensitive to changes in their earnings and to increasing interest rates and inflation, they tend to be more volatile than other types of stocks. In response, from time to time, growth investing as an investment style may go out of favor with investors.
Baron India Fund | General Stock Market [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
General Stock Market. Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. These declines may be the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s). In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non‑performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund’s investments.
Baron India Fund | Large Capitalization Investing Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of these companies underperform the market as a whole. Large-capitalization companies may not be able to attain the high growth rate of successful smaller companies and may adapt more slowly to new competitive challenges, such as changes in technology and consumer tastes, and be subject to slower growth during times of economic expansion.
Baron India Fund | Small and Mid Sized Companies [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Small- and Mid‑Sized Companies. The Adviser believes there is more potential for capital appreciation in small- and mid‑sized companies, but there also may be more risk. Securities of small- and mid‑sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small- and mid‑sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small- and mid‑sized companies rely more on the skills of management and on their continued tenure. Investing in small- and mid‑sized companies requires a long term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies.
Baron India Fund | Financials Sector [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Financials Sector. The financials industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. Uncertainty in the banking and financial systems can result in significant and widespread deterioration in market and economic conditions by disrupting access to capital and other financial services, which could adversely affect the performance of the Fund.
Baron India Fund | Consumer Discretionary Sectors [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Consumer Discretionary Sector. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, inflation, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.

[1] BAMCO (“BAMCO” or the “Adviser”) has agreed that, pursuant to a contract with an 11‑year term terminating on August 29, 2035, it will reimburse certain expenses of the Fund, limiting net annual operating expenses (portfolio transaction costs, interest and dividend expense, acquired fund fees and expenses, fees and expenses related to filing foreign tax reclaims, and extraordinary expenses are not subject to the operating expense limitation) to 1.45% of average daily net assets of Retail Shares, average daily net assets of Retail Shares, 1.20% of average daily net assets of Institutional Shares and 1.20% of average daily net assets of R6 shares. Only the Board of Trustees of the Fund may terminate the expense reimbursement agreement prior to its termination date.
