This Summary Prospectus is intended for use in connection with variable insurance contracts, and is not intended for use by other investors. The Fund’s Prospectus and Statement of Additional Information, each dated April 30, 2026 (as may be supplemented or revised), are incorporated by reference into this Summary Prospectus. For free paper or electronic copies of the Fund’s Prospectus and other information about the Fund, go to nationwide.com/mutualfundsnvit, email a request to web_help@nationwide.com or call 800-848-0920, or ask any variable insurance contract provider who offers shares of the Fund as an underlying investment option in its products.

Objective

The NVIT Investor Destinations Conservative Fund (“Conservative Fund” or the “Fund”) seeks a high level of total return consistent with a conservative level of risk as compared to other Investor Destinations Funds.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. Sales charges and other expenses that may be imposed by variable insurance contracts are not included. If these charges were reflected, the expenses listed below would be higher. See the variable insurance contract prospectus, which may impose sales charges and other additional contract-level expenses.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

	Class II Shares	Class P Shares
Management Fees	0.13%	0.13%
Distribution and/or Service (12b-1) Fees	0.25%	0.25%
Other Expenses	0.20%	0.05%
Acquired Fund Fees and Expenses	0.34%	0.34%
Total Annual Fund Operating Expenses	0.92%	0.77%

Example

This Example is intended to help you to compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example, however, does not include charges that are imposed by variable insurance contracts. If these charges were reflected, the expenses listed below would be higher.

This Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those time periods. It assumes a 5% return each year and no change in expenses, and any expense limitation or fee waivers that may apply for the periods indicated above under “Fees and Expenses.” Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class II Shares	$94	$293	$509	$1,131
Class P Shares	79	246	428	954

Portfolio Turnover

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 65.77% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a “fund-of-funds” that invests primarily in affiliated mutual funds representing a variety of asset classes. The Fund aims to provide diversification across major asset classes—U.S. stocks, international stocks and bonds—by investing primarily in mutual funds offered by Nationwide Variable Insurance Trust and unaffiliated exchange-traded funds (“ETFs”) (each, an “Underlying Fund” or collectively, “Underlying Funds”).

Each Underlying Fund invests directly in equity or fixed-income securities (including mortgage-backed securities), as appropriate to its investment objective and strategies. Certain Underlying Funds are actively managed, and other Underlying Funds are “index” funds, which means they seek to match the investment returns of specified stock or bond indices before the deduction of the Underlying Funds’ expenses. Some Underlying Funds use futures, swaps and options, which are derivatives, either to hedge against investment risks, to obtain exposure to certain securities or groups of securities, to take short positions in certain securities, or otherwise to increase returns. Although the Fund seeks to provide diversification across major asset classes, the Fund invests a significant portion of its assets in a small number of issuers (i.e., Underlying Funds). However, the Fund may invest directly in securities and derivatives in addition to investing in Underlying Funds. Further, the Underlying Funds in which the Fund invests generally are diversified.

The Fund pursues its objective for a high level of total return with a conservative level of risk by investing heavily in Underlying Funds that invest in fixed-income securities, such as bonds, mortgage-backed securities and asset-backed securities, and a relatively small portion of its assets in Underlying Funds that invest in equity securities, such as common stocks of U.S. and international companies (including smaller companies) that the investment adviser believes offer opportunities for capital growth. Consistent with this investment strategy, as of February 27, 2026, the Fund allocated approximately 77% of its net assets in bonds, approximately 16% in U.S. stocks and approximately 7% in international (including emerging markets) stocks. The investment adviser generally sells shares of Underlying Funds in order to meet target allocations or shareholder redemption activity. The Fund is designed for investors who have a low tolerance for risk and whose primary goal is income, or who have a short time horizon.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective.

As with any fund, the value of the Fund’s investments—and therefore, the value of Fund shares—may fluctuate. These changes may occur because of:

Fund-of-funds risk – there are certain risks associated with a structure whereby the Fund invests primarily in other mutual funds. These risks include that: (1) the Fund will indirectly pay a proportional share of the fees and expenses of the Underlying Funds in which it invests; (2) the Fund’s investment performance is directly tied to the performance of the Underlying Funds in which it invests. If one or more Underlying Funds fail to meet their investment objectives, the Fund’s performance will be negatively affected; (3) the Fund is subject to different levels and combinations of risk based on its actual allocation among the various asset classes and Underlying Funds. The potential impact of the risks related to an asset class depends on the size of the Fund’s investment allocation to it; (4) Nationwide Fund Advisors' (the “Adviser”) evaluations and allocation among asset classes and Underlying Funds may be incorrect; (5) the Adviser may add or delete Underlying Funds, or alter the Fund’s asset allocation, at its discretion. Changes to the Fund’s Underlying Funds or allocation (or the lack thereof) could affect both the level of risk and the potential for gain or loss; and (6) in selecting the Underlying Funds in which the Fund invests, the Adviser is subject to a conflict of interest because the Adviser is also the investment adviser to most, if not all, of the Underlying Funds. Although the Fund may invest a portion of its assets in unaffiliated Underlying Funds, there is no assurance that it will do so. To the extent that it is appropriate or suitable for a Fund's investment objective, the Adviser expects to invest in affiliated Underlying Funds without considering or canvassing the universe of unaffiliated Underlying Funds available, even though there may (or may not) be one or more comparable unaffiliated Underlying Funds. The Adviser receives advisory fees from affiliated Underlying Funds and, therefore, has an incentive to invest the Fund’s assets in affiliated Underlying Funds instead of unaffiliated Underlying Funds. In addition, the Adviser might have an interest in making an investment in an affiliated Underlying Fund, or in maintaining an

Summary Prospectus April 30, 2026

NVIT Investor Destinations Conservative Fund

existing investment in an affiliated Underlying Fund, in order to benefit that affiliated Underlying Fund (for example, by assisting the affiliated Underlying Fund in achieving or maintaining scale). Notwithstanding the foregoing, the Adviser has a fiduciary duty to the Fund and must act in the best interest of the Fund.

Exchange-traded funds risk – when the Fund invests in exchange-traded funds (“ETFs”), you will indirectly bear fees and expenses charged by the ETFs in addition to the Fund’s direct fees and expenses. In addition, the Fund will be affected by losses of the ETFs and the level of risk arising from the investment practices of the ETFs (such as the use of leverage by the ETFs). The Fund has no control over the investments and related risks taken by the ETFs in which it invests. Additionally, investments in ETFs are also subject to the following risks: (i) the market price of an ETF’s shares may trade above or below their net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted for a number of reasons.

Management risk – the Fund is subject to the risk that the methods and analyses employed by its investment adviser, or by the investment advisers or subadvisers to the Underlying Funds, will not produce the desired results. This could cause the Fund to lose value or its performance to lag those of relevant benchmarks or other funds with similar objectives.

Market risk – the risk that one or more markets in which an Underlying Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. This occurs due to numerous factors, including interest rates, the outlook for corporate profits, the health of the national and world economies, and the fluctuation of other securities markets around the world. These risks may be magnified if certain social, political, economic and other conditions and events (such as natural disasters, epidemics and pandemics, terrorism, conflicts, trade disputes and social unrest or rapid technological developments such as artificial intelligence) adversely interrupt the global economy.

Equity securities risk – stock markets are volatile. The price of an equity security fluctuates based on changes in a company’s financial condition and overall market and economic conditions.

Fixed-income securities risk – investments in fixed-income securities, such as bonds, subject the Fund to interest rate risk, credit risk and prepayment and call risk, which may affect the value of your investment. Interest rate risk is the risk that the value of fixed-income securities will decline when interest rates rise. Prices of longer-term securities generally change more in response to interest rate changes than prices of shorter-term securities. To the extent an Underlying Fund invests a substantial portion of its assets in debt securities with longer-term maturities, rising interest rates are more likely to cause periods of increased volatility and redemptions, and may

cause the value of the Fund’s investments to decline significantly. The Federal Reserve Board continued to lower interest rates following a period of consistent rate increases, though it is unclear if such lowering will continue. The interest earned on an Underlying Fund's investments in fixed-income securities may decline when prevailing interest rates fall. Declines in interest rates increase the likelihood that debt obligations will be pre-paid, which, in turn, increases these risks. The Fund is subject to the risk that the income generated by its investments in fixed-income securities will not keep pace with inflation. Recent and potential future changes in government policy may affect interest rates.

Credit risk is the risk that the issuer of a bond may default if it is unable to pay interest or principal when due. If an issuer defaults, the Underlying Fund, and therefore the Fund, will lose money. Changes in a bond issuer’s credit rating or the market’s perceptions of an issuer’s creditworthiness also may affect the value of a bond. Prepayment and call risk is the risk that certain debt securities will be paid off by the issuer more quickly than anticipated. If this occurs, an Underlying Fund may be required to invest the proceeds in securities with lower yields.

Liquidity risk – when there is little or no active trading market for specific types of securities or instruments, it can become more difficult to sell the securities or instruments at or near their perceived value. An inability to sell a portfolio position can adversely affect an Underlying Fund's value or prevent an Underlying Fund from being able to take advantage of other investment opportunities. Liquidity risk also includes the risk that an Underlying Fund will experience significant net redemptions of its shares at a time when it cannot find willing buyers for its portfolio securities or instruments or can sell its portfolio securities or instruments only at a material loss. To meet redemption requests, an Underlying Fund may be forced to sell other securities or instruments that are more liquid, but at unfavorable times and conditions. Investments in foreign securities tend to have more exposure to liquidity risk than domestic securities.

Mortgage-backed and asset-backed securities risks – these securities generally are subject to the same types of risk that apply to other debt securities, such as interest rate risk, credit risk, and prepayment and call risk. Mortgage-backed securities also are subject to extension risk, which is the risk that when interest rates rise, certain mortgage-backed securities will be paid in full by the issuer more slowly than anticipated. This can cause the market value of the security to fall because the market may view its interest rate as low for a longer-term investment. Through its investments in mortgage-backed securities, an Underlying Fund may have some exposure to subprime loans, as well as to the mortgage and credit markets generally. Subprime loans, which are loans made to borrowers with weakened credit histories, generally have higher default rates than loans that meet government underwriting requirements. The credit quality of most asset-backed securities depends primarily on the credit quality of the assets

Summary Prospectus April 30, 2026

NVIT Investor Destinations Conservative Fund

underlying such securities, how well the entity issuing the security is insulated from the credit risk of the originator or any other affiliated entities, and the amount and quality of any credit enhancement of the securities.

Foreign securities risk – foreign securities often are more volatile, harder to price and less liquid than U.S. securities. The prices of foreign securities may be further affected by other factors, such as changes in the exchange rates between the U.S. dollar and the currencies in which the securities are traded.

Emerging markets risk – emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets are considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. Since these markets are smaller than developed markets, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because the Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries are unreliable compared to developed markets. Companies in emerging market countries generally are subject to less stringent financial reporting, accounting and auditing standards than companies in more developed countries. In addition, information about such companies may be less available and reliable. Many emerging markets also have histories of political instability and abrupt changes in policies, and the ability to bring and enforce actions may be limited. Certain emerging markets also face other significant internal or external risks, including the risk of war, nationalization of assets, unexpected market closures and ethnic, religious and racial conflicts.

Smaller company risk – smaller companies are usually less stable in price and less liquid than larger, more established companies. Smaller companies are more vulnerable than larger companies to adverse business and economic developments and may have more limited resources. Therefore, they generally involve greater risk.

Index fund risk – an Underlying Fund that seeks to match the performance of an index does not use defensive strategies or attempt to reduce its exposure to poorly performing securities. Further, correlation between an Underlying Fund’s performance and that of the index is likely to be negatively affected by the Underlying Fund’s expenses, changes in the composition of the index, and the timing of purchase and redemption of Underlying Fund shares.

Limited portfolio holdings risk – because the Fund may hold large positions in an Underlying Fund, an increase or decrease in the value of such securities will have a greater impact on the Fund’s value and total return. Funds that invest in a relatively small number of securities may be subject to greater volatility than a more diversified investment.

Derivatives risk – derivatives may be volatile and may involve significant risks. The underlying security, commodity, measure or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Normally derivatives involve leverage, which means that their use can significantly magnify the effect of price movements of the underlying securities or reference measures, disproportionately increasing a Fund's or Underlying Fund's losses and reducing the Fund's or Underlying Fund's opportunities for gains. Some derivatives have the potential for unlimited loss, including a loss that may be greater than the amount invested. They also present default risks if the counterparty to a derivatives contract fails to fulfill its obligations to the Fund or Underlying Fund. Certain derivatives held by a Fund or Underlying Fund may be illiquid, making it difficult to close out an unfavorable position.

Futures – the prices of futures contracts typically are more volatile than those of stocks and bonds. Small movements in the values of the assets or measures of underlying futures contracts can cause disproportionately larger losses to the Fund or an Underlying Fund. While futures may be more liquid than other types of derivatives, they may experience periods when they are less liquid than stocks, bonds or other investments.

Options – purchasing and writing put and call options are highly specialized activities and entail greater-than-ordinary investment risks. Investments in options are considered speculative. An option is an agreement that, for a premium payment or fee, gives the option holder (the purchaser) the right but not the obligation to buy (a “call option”) or sell (a “put option”) the underlying security or futures contract (or settle for cash an amount based on an underlying asset, rate or index) at a specified price (the “exercise price”) during a period of time or on a specified date. When the Underlying Fund writes (sells) an option, it profits if the option expires unexercised, because it retains the premium the buyer of the option paid. However, if the Underlying Fund writes a call option, it incurs the risk that the market price of the underlying security or futures contract will increase above the option's exercise price. If this occurs, the option could be exercised and the Underlying Fund would be forced to sell the underlying security or futures contract at a lower price than its current market value. If the Underlying Fund writes a put option, it incurs the risk that the market value of the underlying security or futures contract will decrease below the option's exercise price. If this occurs, the option could be exercised and the Underlying Fund would be forced to buy the underlying security or futures contract at a higher price than its current

Summary Prospectus April 30, 2026

NVIT Investor Destinations Conservative Fund

market value. When the Underlying Fund purchases an option, it will lose the premium paid for the option if the price of the underlying security or futures contract decreases or remains the same (in the case of a call option) or increases or remains the same (in the case of a put option). If an option purchased by the Underlying Fund were permitted to expire without being sold or exercised, its premium would represent a loss to the Fund.

Swaps – using swaps can involve greater risks than if an Underlying Fund were to invest directly in the underlying securities or assets. Because swaps often involve leverage, their use can significantly magnify the effect of price movements of the underlying securities or reference measures, disproportionately increasing an Underlying Fund's losses and reducing an Underlying Fund's opportunities for gains. Currently there are few central exchanges or markets for swap contracts, and therefore they may be less liquid than exchange-traded instruments. If a swap counterparty fails to meet its obligations under the contract, the Underlying Fund will lose money.

Short sales risk – the Fund will suffer a loss if an Underlying Fund takes a short position in a security and the price of the security rises rather than falls. Short positions expose the Underlying Fund to the risk that it will be required to cover the short position at a time when the security has appreciated in value, thus resulting in a loss to the Fund. The Fund’s investment performance also will suffer if an Underlying Fund is required to close out a short position earlier than it had intended. In addition, an Underlying Fund will be subject to expenses related to short positions that typically are not associated with investing in securities directly (for example, costs of borrowing and margin account maintenance costs associated with the Underlying Fund’s open short positions). These expenses will impact negatively the performance of the Fund. Short positions introduce more risk to an Underlying Fund than long positions because the maximum sustainable loss on a security purchased (held long) is limited to the amount paid for the security plus the transaction costs, whereas there is no maximum attainable price of the security held in a short position. Therefore, in theory, securities held short present unlimited risk.

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows the volatility or variability of the Fund’s annual total returns over time and shows that Fund performance can change from year to year. The table shows the Fund’s average annual total returns for certain time periods compared to the returns of a broad-based securities market index. Remember, however,

that past performance is not necessarily an indication of how the Fund will perform in the future. The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance contracts. If these amounts were reflected, returns would be less than those shown.

The Fund compares its performance to the Bloomberg U.S. Aggregate Bond Index to satisfy a Securities and Exchange Commission (SEC) disclosure requirement.

Tax Information

The dividends and distributions paid by the Fund to the insurance company separate accounts will consist of ordinary income, capital gains, or some combination of both. Because shares of the Fund must be purchased through separate accounts used to fund variable insurance contracts, such dividends and distributions will be exempt from current taxation by contract holders if left to accumulate within a separate account. Consult the variable insurance contract prospectus for additional tax information.

Payments to Broker-Dealers and Other Financial Intermediaries

This Fund is only offered as an underlying investment option for variable insurance contracts. The Fund and its related companies may make payments to the sponsoring insurance companies (or their affiliates) for distribution and/or other services, and to broker-dealers and other financial intermediaries that distribute the variable insurance contracts. These payments may create a conflict of interest by influencing the insurance companies to include the Fund as an underlying investment option in the variable insurance contracts, and by influencing the broker-dealers and other financial intermediaries to distribute variable insurance contracts that include the Fund as an underlying investment option over other variable insurance contracts or to otherwise recommend the selection of the Fund as an underlying investment option by contract owners instead of other funds that also may be available investment options. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.
