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 7% of the average value of its portfolio.

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 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 actual costs may be higher or lower, based on these assumptions your costs would be:
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 because it invests, at any given time, in the securities of a select number of Baron mutual funds (the “Underlying Funds”), representing specific investment strategies. The Fund normally invests in a variety of domestic and international equity funds. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation.
The Fund can invest in funds holding U.S. and international stocks; small-cap, small- to mid-cap, mid-cap, large-cap, all-cap stocks; and sector specific stocks.
The portfolio manager decides how much of the Fund’s assets to allocate to underlying fund investments based on the outlook for, and on the relative valuations of, the Underlying Funds and the various markets in which they invest.

The Fund may sell shares of the Underlying Funds for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities. The Fund may also modify the list of Underlying Funds at any time, including by adding Underlying Funds that may be created in the future, or change the Fund’s asset allocation at any time, in each case without prior approval from or notice to shareholders. At certain periods, the Fund may hold
a portion of its assets in cash, money market securities or other similar liquid investments.

Baron WealthBuilder 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 WealthBuilder 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 assets 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 WealthBuilder Fund | Asset Allocation [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Asset Allocation. The Fund’s ability to achieve its investment objective depends largely upon selecting the best mix of Underlying Funds. The selection of the Underlying Funds and the allocation of the Fund’s assets among the various market sectors could cause the Fund to underperform in comparison to other funds with a similar investment objective.
Baron WealthBuilder 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. 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 WealthBuilder Fund | Risks of Investing in the Underlying Funds [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Risks of Investing in the Underlying Funds. Each of the Underlying Funds has its own investment risks, and those risks can affect the value of the Fund’s investments and therefore the value of the Fund’s shares. To the extent that the Fund invests more of its assets in one Underlying Fund than in another, it will have greater exposure to the risks of that Underlying Fund.
Baron WealthBuilder 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.
Baron WealthBuilder Fund | Developing Countries [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Developing Countries. Certain Underlying Funds invest in developing countries, which include countries in the MSCI Emerging Markets (EM) Index, countries in the MSCI Frontier Markets (FM) Index and other countries determined by the Adviser to be developing countries based on classifications made by the International Monetary Fund or on country characteristics similar to those of the countries in the EM and FM Indexes. Investments in developing countries 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. These risks are greater for countries in the FM Index.
Baron WealthBuilder 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 WealthBuilder Fund | Information Technology Sectors [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Information Technology Sector. Companies in the information technology sector are subject to rapid changes in technology product cycles; rapid product obsolescence; government regulation; and increased competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies and companies that rely heavily on technology tend to be more volatile than the overall market and also are heavily dependent on patent and intellectual property rights. In addition, information technology companies may have limited product lines, markets, financial resources or personnel.
Baron WealthBuilder Fund | Industrials Sector [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Industrials Sector. The Fund’s investments are exposed to issuers conducting business in the Industrials Sector. The Industrials Sector includes manufacturers and distributors of capital goods such as aerospace and defense, building projects, electrical equipment and machinery and companies that offer construction and engineering services. It also includes providers of commercial and professional services including printing, environmental and facilities services, office services and supplies, security and alarm services, human resource and employment services, research and consulting services. It also includes companies that provide transportation services. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Industrials Sector. The prices of the securities of companies operating in the Industrials Sector may fluctuate due to the level and volatility of commodity prices, the exchange value of the dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.
Baron WealthBuilder Fund | Large Cap Companies [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Large-Cap Companies. Because an Underlying Fund may invest primarily in large-cap company securities, that Underlying Fund may underperform other funds during periods when their securities are out of favor.
Baron WealthBuilder Fund | Non U S Securities [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Non-U.S. Securities. Investing in non-U.S. 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.
Baron WealthBuilder 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 WealthBuilder Fund | Technology [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Technology. Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions.
