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.

| 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 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 the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

| Strategy [Heading] | oef_StrategyHeading | Principal Investment Strategies of the Fund | |||||||||||||
| Strategy Narrative [Text Block] | oef_StrategyNarrativeTextBlock | 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 assets in a balanced portfolio of common stock, preferred stock and bonds. The Fund may also hold cash. The Fund may invest in large, medium or small companies without regard
to market capitalization and may invest in securities issued by either domestic or foreign companies.
The Fund’s investments in common stock issued by companies across the spectrum of market capitalizations are purchased primarily for their growth potential. Fixed income securities, consisting of both
investment grade and high-yield, high-risk debt securities (“junk bonds”), are purchased both for current income and to provide diversification.
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.

| Bar Chart and Performance Table [Heading] | oef_BarChartAndPerformanceTableHeading | Performance Results | |||||||||||||
| Performance Narrative [Text Block] | oef_PerformanceNarrativeTextBlock | The bar chart below provides some indication of the risks of investing in the Fund by showing how the Fund’s investment results have varied from year to year. The following table shows how the Fund’s average annual total returns, for the periods indicated, compare with the S&P 500 Index, a broad-based securities market index, and the Bloomberg U.S. Aggregate Bond Index. The Bloomberg U.S. Aggregate Bond Index is a measure of the performance of the investment grade, US Dollar-denominated, fixed-rate taxable bond market. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.davisfunds.com or by calling 1-800-279-0279.
After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares; after-tax returns for other share classes will vary.

| Davis Balanced Fund | Davis Series | Common Stock Risk [Member] | |||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | ||||||||||||||
| 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.

| 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.

| 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.

| 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.

| Risk [Text Block] | oef_RiskTextBlock | Preferred Stock Risk. Preferred stock is a form of equity security and is generally ranked behind an issuer’s debt securities in claims for dividends and assets of an issuer in a liquidation or bankruptcy. An adverse event may have a negative impact on a company and could result in a decline in the price of its preferred stock.

| Risk [Text Block] | oef_RiskTextBlock | Bonds and Other Debt Securities Risk. Corporations, governments and other issuers sell bonds and other debt securities to borrow money.

| Davis Balanced Fund | Davis Series | Extension and Prepayment Risk [Member] | |||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | ||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Extension and Prepayment Risk. Extension risk occurs when borrowers maintain their existing debt obligations until they come due instead of choosing to prepay them. Prepayment risk occurs when borrowers prepay their debt obligations more quickly than usual so that they can refinance at a lower rate. The pace at which borrowers prepay affects the yield and the cash flow to holders of securities and the market value of those securities.

| Davis Balanced Fund | Davis Series | 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 Balanced Fund | Davis Series | 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 Balanced Fund | Davis Series | 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.

| 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.

| Davis Balanced Fund | Davis Series | High-Yield [Member] | |||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | ||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | High-Yield, High-Risk Debt Securities Risk. Issuers of these debt securities are unlikely to have a cushion from which to make their payments when their earnings are poor or when the economy in general is in decline. These issuers are likely to have a substantial amount of other debt, which will be senior to the high-yield, high-risk debt securities. An issuer must be current on its senior obligations before it can pay bondholders.

| Davis Balanced Fund | Davis Series | Shareholder Concentration Risk [Member] | |||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | ||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Shareholder Concentration Risk. From time to time, a relatively large percentage (over 20%) of the Fund’s shares may be held by related shareholders. A large redemption by one or more of such shareholders may: (1) reduce the Fund’s liquidity, (2) increase the Fund’s transactions and transaction costs, (3) result in substantial capital gains distributions for shareholders, and (4) increase the Fund’s ongoing operating expenses, which could negatively impact the remaining shareholders of the Fund.
