Best Mutual Funds in 2026: A Roth IRA is a retirement account where the money can grow for many years. If the rules are followed, the money you take out later in retirement can be tax-free. That makes the account very useful for long-term investing. The IRS says Roth IRA qualified distributions are not taxed, but early or nonqualified withdrawals can be taxed and may also face a 10% extra tax. Usually, the Roth IRA also needs to meet the five-year rule, and the person must be at least 59½, unless an exception applies.
For 2026, the IRA contribution limit is higher than it was before. The IRS raised the annual IRA limit to $7,500. People who are 50 or older can add a $1,100 catch-up amount. That makes the total $8,600 for 2026. This limit is for all traditional IRA and Roth IRA contributions combined, not each account separately.
Why low-cost funds are often best for a Roth IRA
A Roth IRA is usually best for long-term investing, not quick trading. Low-cost mutual funds can fit well because lower fees leave more money to grow over time.
Mutual funds are easy because one fund invests in many companies instead of just one, which helps lower risk.
- Younger investors often choose more stock funds for higher growth.
- Older investors may prefer bond funds or balanced funds because they are usually more stable.

The best choice depends on the person. A 25-year-old may want mostly stocks, while a 60-year-old may want a safer mix. Someone who wants things easy may choose one target-date fund, while someone who wants more control may use U.S. stock, international stock and bond funds.

Strong U.S. Stock Mutual Funds for Roth IRA growth
A broad U.S. stock fund is one of the most common starting points for a Roth IRA. These funds give exposure to many big American companies. They are simple and cheap. They can go down when the stock market falls, but they have also been a strong long-term tool for many retirement investors.
Fidelity 500 Index Fund
This fund follows the S&P 500. That means it gives exposure to many of the biggest U.S. companies. Fidelity lists the fund’s net expense ratio at 0.015%. That is very low. It can work as a core Roth IRA holding for people who want simple U.S. large-company exposure.
Schwab Total Stock Market Index Fund
Instead of only tracking the S&P 500, it tries to follow the whole U.S. stock market. Schwab lists its total expense ratio at 0.030%.
Schwab also says the fund tracks the Dow Jones U.S. Total Stock Market Index and had 2,950 holdings as of May 31, 2026. That gives wider U.S. stock coverage than an S&P 500-only fund.
Fidelity ZERO Total Market Index Fund
It is also popular with cost-focused investors because it has a 0% expense ratio. It gives broad U.S. stock exposure and has no minimum investment. This can be useful for new Roth IRA investors who are starting small and want every dollar invested without paying a fund expense ratio.

A person does not usually need all three of these funds together. They overlap a lot. FXAIX owns large U.S. companies. SWTSX and FZROX own the wider U.S. market. For many people, one broad U.S. stock fund is enough for the U.S. part of the Roth IRA.
International Funds Can Help
A Roth IRA does not have to hold only U.S. stocks. International funds can help because they give access to companies outside the United States. This matters because the U.S. market will not always be the strongest market every year. International investing can help spread the account across more countries.
Fidelity ZERO International Index Fund
Fidelity ZERO International Index Fund, with ticker FZILX:
- It is a low-cost way to add international stock exposure
- It has a 0% expense ratio
- It can be used beside a U.S. stock index fund so the Roth IRA is not only tied to American companies
Schwab International Index Fund
Schwab International Index Fund, with ticker SWISX, is another international mutual fund. Schwab lists its total expense ratio at 0.060%. The fund’s goal is to track large publicly traded non-U.S. companies from developed markets outside the United States. Schwab also says the fund invests across 21 developed markets in Europe, Australasia and the Far East.
International funds can still fall in value. They are not safe just because they are outside the U.S. They can be affected by currency changes, world events and weaker foreign markets. But they can still be useful because they reduce the risk of putting everything in one country.
Bond Funds
Bond funds are not usually the main growth engine in a Roth IRA. Stocks usually have more long-term growth potential. But bonds can help make the account less wild. They can be useful for older investors, nervous investors or people who are getting close to using the money.
Vanguard Total Bond Market Index Fund Admiral Shares, with ticker VBTLX, is one broad bond fund option. Vanguard’s bond fund is often used as a simple U.S. bond market holding. Recent fund information lists a very low 0.04% expense ratio.

Target-date Funds
Some investors do not want to manage several Roth IRA funds. For them, a target-date fund can be a simple choice. The investor picks a fund close to their expected retirement year. The fund starts with more growth-focused investments and slowly becomes more conservative as retirement gets closer.
Vanguard Target Retirement 2060 Fund
Vanguard Target Retirement 2060 Fund, or VTTSX, is one example. Vanguard says its target retirement funds move from aggressive to conservative investments over time. Its Target Retirement Funds have an average expense ratio of 0.08%, compared with the industry average of 0.41% for similar funds as of December 31, 2025.
A target-date fund can work well for people who want a simple “set it and forget it” option. It gives stock, bond, U.S. and international exposure in one fund.
Balanced Funds
T. Rowe Price Capital Appreciation Fund, or PRWCX, holds stocks and may also hold bonds and other securities. Its recent net expense ratio was 0.71%, which is higher than many index funds. That does not make it bad, but investors should understand the higher cost before choosing it.
How To Choose the Best Mutual Funds
Choosing a mutual fund involves multiple considerations. That’s why the Forbes Advisor list for the best mutual funds to invest in involves several screens. Common screens for choosing mutual funds include:
- Performance
- Assets under management (AUM)
- Type of management, whether active or passive
- Equity exposure (e.g., sectors, or U.S equities, etc.)
- Market cap of equities
- Seeking yield or share appreciation
- Turnover rate
