The tables below illustrate the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts in Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in Virtus Funds. More information on these and other discounts is available: (i) from your financial professional or other financial intermediary; (ii) under “Sales Charges” on page 77 of the fund’s prospectus; and (iii) with respect to purchase of shares through specific intermediaries, in Appendix A to the fund’s prospectus, entitled “Intermediary Sales Charge Discounts and Waivers.”

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 37% of the average value of its portfolio.

Expense Example Narrative [Text Block] oef_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 or continued to hold them. The example also assumes that your investment has a 5% return each year, that the fund’s operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

The fund will invest in securities of issuers located throughout the world, including the United States (“U.S.”). Under normal circumstances, the fund will invest primarily in equity securities, with at least 40% of the fund’s net assets in issuers organized, headquartered or doing a substantial amount of business outside the U.S. As of the date of

this prospectus, the fund’s subadviser, Sustainable Growth Advisers, LP (“SGA”), considers an issuer that has at least 50% of its assets or derives at least 50% of its revenue from business outside the U.S. as doing a substantial amount of business outside the U.S. The fund may invest up to 25% of its net assets in the securities of companies located in countries included in the MSCI Emerging Markets Index.

SGA uses an investment process to identify companies that it believes have a high degree of predictability, strong profitability and above average earnings and cash flow growth. SGA selects investments for the fund’s portfolio that it believes have superior long-term earnings prospects and attractive valuation. To the extent consistent with the fund’s investment objective and strategies, the subadviser will consider as an element of its investment research and decision making processes for the fund any environmental, social and/or governance (“ESG”) factors that the subadviser believes may influence risks and opportunities of companies under consideration. However, the pursuit of ESG-related goals is not the fund’s investment objective, nor one of its investment strategies. Therefore, ESG factors by themselves are not expected to determine investment decisions for the fund. The fund’s equity investments may include common stocks, preferred stocks, securities convertible into or exchangeable for common stocks, and depositary receipts. The fund typically invests in large and medium capitalization companies, but it is permitted to invest in companies of any capitalization. The fund will allocate its assets among various regions and countries (but no fewer than three non-U.S. countries). From time to time, the fund may have a significant portion of its assets invested in the securities of companies in only a few countries and one or a few regions. Although the fund seeks investments across a number of sectors, from time to time, the fund may have significant positions in particular sectors.

SGA will sell a portfolio holding when it believes the security’s fundamentals deteriorate, its valuation is no longer attractive, or a better investment opportunity arises.

Performance Narrative [Text Block] oef_PerformanceNarrativeTextBlock

The fund is the successor of American Beacon SGA Global Growth Fund, a series of American Beacon Funds (“Predecessor Fund”), resulting from a reorganization of the Predecessor Fund with and into the fund, which occurred on May 3, 2019. The fund has adopted the past performance of the Predecessor Fund as its own.

Principal Risks

The fund may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The principal risks of investing in the fund are identified below.

Virtus SGA Global Growth Fund | Equity Securities Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Equity Securities Risk: The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.
Virtus SGA Global Growth Fund | Foreign Investing Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.
Virtus SGA Global Growth Fund | Emerging Market Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Emerging Market Risk: Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. Such securities may also be subject to Sanctions Risk.
Virtus SGA Global Growth Fund | Sanctions Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Sanctions Risk: The imposition of sanctions and other similar measures could cause a decline in the value and/or liquidity of securities issued by or tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of transactions, and negatively impact the fund’s liquidity and performance.
Virtus SGA Global Growth Fund | Market Volatility Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.
Virtus SGA Global Growth Fund | Limited Number of Investments Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Limited Number of Investments Risk: Because the fund may have a limited number of securities, it may be more susceptible to factors adversely affecting its securities than a fund with a greater number of securities.
Virtus SGA Global Growth Fund | Sector Focused Investing Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Sector Focused Investing Risk: Events negatively affecting a particular market sector in which the fund focuses its investments may cause the value of the fund’s shares to decrease, perhaps significantly.
Virtus SGA Global Growth Fund | Focused Investment Risk (Technology-Related Risk)  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Focused Investment Risk (Technology-Related Risk): To the extent the fund focuses its investments on a limited number of issuers, sectors, industries or geographic regions, it may be subject to increased risk and volatility. Risks affecting companies in the technology sector include competition from new and existing companies, limited operating histories and management experience, patent and other intellectual property considerations and the commercial non-viability or rapid obsolescence of equipment, products or services.
Virtus SGA Global Growth Fund | Currency Rate Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Currency Rate Risk: Fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect the value of the fund’s shares.
Virtus SGA Global Growth Fund | Depositary Receipts Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Depositary Receipts Risk: Investments in foreign companies through depositary receipts may expose the fund to the same risks as direct investments in securities of foreign issuers.
Virtus SGA Global Growth Fund | Convertible Securities Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Convertible Securities Risk: The value of a convertible security may decline as interest rates rise and/or vary with fluctuations in the market value of the underlying securities. The security may be called for redemption at a time and/or price unfavorable to the fund.

 
Virtus SGA Global Growth Fund | ESG Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> ESG Risk: The fund’s consideration of ESG factors could cause the fund to perform differently from other funds. While the subadviser believes that the integration of ESG factors into the fund’s investment process has the potential to contribute to performance, ESG factors may not be considered for every investment decision and there is no guarantee that the integration of ESG factors will result in better performance.
Virtus SGA Global Growth Fund | Geographic Concentration Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Geographic Concentration Risk: A fund that focuses its investments in a particular geographic location will be sensitive to financial, economic, political and other events negatively affecting that location and may cause the value of the fund to decrease, perhaps significantly.
Virtus SGA Global Growth Fund | Growth Stocks Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Growth Stocks Risk: The fund’s investments in growth stocks may be more volatile than investments in other types of stocks, or may perform differently from the market as a whole and from other types of stocks.
Virtus SGA Global Growth Fund | Large Market Capitalization Companies Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Large Market Capitalization Companies Risk: The value of investments in larger companies may not rise as much as smaller companies, or larger companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
Virtus SGA Global Growth Fund | Medium Market Capitalization Companies Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Medium Market Capitalization Companies Risk: The fund’s investments in medium market capitalization companies may increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies.
Virtus SGA Global Growth Fund | Preferred Stocks Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Preferred Stocks Risk: Preferred stocks may decline in price, fail to pay dividends when expected, or be illiquid.
Virtus SGA Global Growth Fund | Redemption Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s NAV and liquidity. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio.

The fund’s investment adviser has contractually agreed to limit the fund’s total operating expenses (excluding certain expenses, such as front-end or contingent deferred sales charges, taxes, leverage and borrowing expenses (such as commitment, amendment and renewal expenses on credit or redemption facilities), interest, brokerage commissions, expenses incurred in connection with any merger or reorganization, unusual or infrequently occurring expenses (such as litigation), acquired fund fees and expenses, and dividend expenses, if any) so that such expenses do not exceed 1.25% for Class A Shares, 2.00% for Class C Shares, 1.00% for Class I Shares and 0.90% for Class R6 Shares through January 31, 2027. Prior to January 31, 2027, only the fund’s Board may modify or terminate the expense limitation agreement. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed and/or fees waived under these arrangements for a period of three years following the date such waiver or reimbursement occurred, provided that the recapture does not cause the fund to exceed its expense limit in effect at the time of the waiver or reimbursement, and any in effect at the time of recapture, after repayment is taken into account.
