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. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover [Text Block] oef_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. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 15% of the average value of its portfolio.

Davis Selected Advisers, L.P. (“Davis Advisors” or the “Adviser”), the Fund’s investment adviser, uses the Davis Investment Discipline to invest the Fund’s portfolio principally in common stocks (including indirect holdings of common stock through Depositary Receipts (as defined below)) issued by large companies with market capitalizations of at least $10 billion. Historically, the Fund has invested a significant portion of its assets in financial services companies and in foreign companies, and may also invest in mid- and small-capitalization companies.
Davis Investment Discipline. Davis Advisors manages equity funds using the Davis Investment Discipline. Davis Advisors conducts extensive research to try to identify businesses that possess characteristics that Davis Advisors believes foster the creation of long-term value, such as proven management, a durable franchise and business model, and sustainable competitive advantages. Davis Advisors aims to invest in such businesses when they are trading at discounts to their intrinsic worth. Davis Advisors emphasizes individual stock selection and believes that the ability to evaluate management is critical. Davis Advisors routinely visits managers at their places of business in order to gain insight into the relative value of different businesses. Such research, however rigorous, involves predictions and forecasts that are inherently uncertain. After determining which companies Davis Advisors believes the Fund should own, Davis Advisors then turns its analysis to determining the intrinsic value of those companies’ equity securities. Davis Advisors seeks companies whose equity securities can be purchased at a discount from Davis Advisors’ estimate of the company’s intrinsic value based upon fundamental analysis of cash flows, assets and liabilities, and other criteria that Davis Advisors deems to be material on a company-by-company basis. Davis Advisors’ goal is to invest in companies for the long term (ideally, five years or longer, although this goal may not be met). Davis Advisors considers selling a company’s equity securities if the securities’ market price exceeds Davis Advisors’ estimates of intrinsic value, if the ratio of the risks and rewards of continuing to own the company’s equity securities is no longer attractive, to raise cash to purchase a more attractive investment opportunity, to satisfy net redemptions, or for other purposes.

Risk [Text Block] oef_RiskTextBlock
Financial Services Risk. Risks of investing in the financial services sector include: (1) systemic risk: factors outside the control of a particular financial institution may adversely affect the ability of the financial institution to operate normally or may impair its financial condition; (2) regulatory actions: financial services companies may suffer setbacks if regulators change the rules under which they operate; (3) changes in interest rates: unstable and/or rising interest rates may have a disproportionate effect on companies in the financial services sector; (4) non-diversified loan portfolios: financial services companies may have concentrated portfolios that make them vulnerable to economic conditions that affect an industry; (5) credit: financial services companies may have exposure to investments or agreements that may lead to losses; and (6) competition: the financial services sector has become increasingly competitive.

Risk [Text Block] oef_RiskTextBlock
Common Stock Risk. Common stock represents an ownership position in a company. An adverse event may have a negative impact on a company and could result in a decline in the price of its common stock. Common stock is generally subordinate to an issuer’s other securities, including preferred, convertible, and debt securities.

Davis Equity Portfolio | Davis Variable Account Fund | Foreign Country Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Foreign Country Risk. Securities of foreign companies (including Depositary Receipts) may be subject to greater risk, as foreign economies may not be as strong or diversified, foreign political systems may not be as stable and foreign financial reporting standards may not be as rigorous as they are in the United States. There may also be less information publicly available regarding the non-U.S. issuers and their securities. These securities may be less liquid (and, in some cases, may be illiquid) and could be harder to value than more liquid securities.
Davis Equity Portfolio | Davis Variable Account Fund | China Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
China Risk – Generally. Investment in Chinese securities may subject the Fund to risks that are specific to China. China may be subject to significant amounts of instability, including, but not limited to, economic, political, and social instability. China’s economy may differ from the U.S. economy in certain respects, including, but not limited to, general development, level of government involvement, wealth distribution, and structure.
The Fund may invest in securities issued by variable interest entities (“VIEs”), which are subject to the investment risks associated with the underlying Chinese operating company. A VIE enters into service contracts and other contracts with the Chinese operating company, which provide the VIE with exposure to the company. Although the VIE has no equity ownership of the Chinese operating company, the contractual arrangements permit the VIE to consolidate the Chinese operating company into its financial statements. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese operating company’s performance and the enforceability of the VIE’s contractual arrangements with the Chinese company.
Davis Equity Portfolio | Davis Variable Account Fund | Headline Risk [Member]

Risk [Text Block] oef_RiskTextBlock
Headline Risk. The Fund may invest in a company when the company becomes the center of controversy after receiving adverse media attention concerning its operations, long-term prospects, management, or for other reasons. While Davis Advisors researches companies subject to such contingencies, it cannot be correct every time, and the company’s stock may never recover or may become worthless.
Davis Equity Portfolio | Davis Variable Account Fund | Large-Capitalization Companies Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Large-Capitalization Companies Risk. Companies with $10 billion or more in market capitalization are considered by the Adviser to be large-capitalization companies. Large-capitalization companies generally experience slower rates of growth in earnings per share than do mid- and small-capitalization companies.
Davis Equity Portfolio | Davis Variable Account Fund | Manager Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Manager Risk. Poor security selection or focus on securities in a particular sector, category, or group of companies may cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective. Even if the Adviser implements the intended investment strategies, the implementation of the strategies may be unsuccessful in achieving the Fund’s investment objective.
Davis Equity Portfolio | Davis Variable Account Fund | Depositary Receipts Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Depositary Receipts Risk. Depositary Receipts, consisting of American Depositary Receipts, European Depositary Receipts, and Global Depositary Receipts, are certificates evidencing ownership of shares of a foreign issuer. Depositary Receipts are subject to many of the risks associated with investing directly in foreign securities. Depositary Receipts may trade at a discount, or a premium, to the underlying security and may be less liquid than the underlying securities listed on an exchange.
Davis Equity Portfolio | Davis Variable Account Fund | Emerging Market Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Emerging Market Risk. Securities of issuers in emerging and developing markets may offer special investment opportunities, but present risks relating to political, economic, or regulatory conditions not found in more mature markets, such as government controls on foreign investments, government restrictions on the transfer of securities, and less developed trading markets, exchanges, reporting standards, and legal and accounting systems. These securities may be more volatile and less liquid, which may also make them more difficult to value than securities in countries with developed economies.
Davis Equity Portfolio | Davis Variable Account Fund | Fees and Expenses Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Fees and Expenses Risk. The Fund may not earn enough through income and capital appreciation to offset the operating expenses of the Fund. All mutual funds incur operating fees and expenses. Fees and expenses reduce the return that a shareholder may earn by investing in a fund, even when a fund has favorable performance. A low-return environment, or a bear market, increases the risk that a shareholder may lose money.
Davis Equity Portfolio | Davis Variable Account Fund | Foreign Currency Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Foreign Currency Risk. The change in value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of securities denominated in that foreign currency. For example, when the Fund holds a security that is denominated in a foreign currency, a decline of that foreign currency against the U.S. dollar would generally cause the value of the Fund’s shares to decline.
Davis Equity Portfolio | Davis Variable Account Fund | Mid- and Small-Capitalization Companies Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Mid- and Small-Capitalization Companies Risk. Companies with less than $10 billion in market capitalization are considered by the Adviser to be mid- or small-capitalization companies. Mid- and small-capitalization companies typically have more limited product lines, markets, and financial resources than larger companies and their securities may trade less frequently and in more limited volume than those of larger, more mature companies.
