A Roth IRA doesn't earn a fixed interest rate—it earns whatever return the investments inside it generate

A Roth IRA is a container for investments, not an investment itself. The money you put in doesn't sit earning interest like it would in a savings account. Instead, you choose what to invest in—stocks, bonds, mutual funds, or other securities—and those investments generate the returns. A stock fund might return 8% one year and lose 5% the next. A bond fund might return 3% consistently. A money market fund might return 4% to 5%. The interest or growth you earn depends entirely on what you pick and how those investments perform.

This is the key difference between a Roth IRA and a high-yield savings account. A savings account promises you a specific rate—currently around 4% to 5% at many banks—and that's what you'll earn. A Roth IRA promises you tax-free growth on whatever you invest, but it doesn't promise what that growth will be. You're trading a may provide small return for the possibility of a larger one, with the risk that it could be smaller or even negative in any given year.

Key Takeaways

  • A Roth IRA earns returns based on what you invest in, not from a fixed interest rate the account itself pays.
  • Conservative investments like bond funds or money market funds typically return 3% to 5% annually, while stock-heavy portfolios historically average around 7% to 10% over long periods.
  • Your actual return depends on which specific funds or stocks you choose, when you buy and sell them, and how long you hold them.
  • Some Roth IRAs do offer a fixed-rate option through certificates of deposit (CDs), which guarantees a specific return but usually lower than stock investments over time.

What determines the return on your Roth IRA investments

The return you earn comes from three sources: interest paid by bonds, dividends paid by stocks, and price appreciation when the value of what you own goes up. If you invest in a bond fund, you earn the interest the bonds pay. If you invest in a stock fund, you earn dividends (if the companies pay them) plus gains when the stock price rises. If you invest in a target-date fund—a fund that automatically shifts from stocks to bonds as you approach retirement—you earn a mix of all three.

The specific funds available to you depend on which bank or brokerage holds your Roth IRA. Vanguard, Fidelity, Charles Schwab, and other major firms each offer different fund lineups. A Vanguard Total Stock Market Index Fund might charge a very low fee and track the entire U.S. stock market, while a different provider's stock fund might charge more and underperform. The fee structure matters: a fund that charges 0.03% annually will leave you with more money than one charging 1% annually, even if both hold the same stocks.

Historical returns for different investment types

The U.S. stock market has historically returned around 10% annually over very long periods—decades—but that includes years of 20% gains and years of 30% losses. A diversified stock portfolio (a mix of U.S. stocks, international stocks, and some bonds) typically returns 7% to 8% annually over long periods. A bond-heavy portfolio returns 3% to 5%. A money market fund or short-term CD returns whatever the current interest rate is, usually 4% to 5% right now but lower in other years.

These are historical averages, not promises. The stock market returned about 28% in 2023 and lost about 18% in 2022. Someone who invested heavily in 2022 and held through 2023 came out ahead despite the loss. Someone who invested in 2023 and saw a downturn in 2024 would be down. Time horizon matters enormously: if you're 25 and won't touch the money for 40 years, a year of losses is a blip. If you're 60 and plan to start withdrawing in five years, a major loss is a real problem.

Why your Roth IRA provider offers different investment choices

Banks and brokerages offer a range of investments because different people have different risk tolerance and time horizons. A 25-year-old with 40 years until retirement can afford to ride out market swings and might choose an aggressive stock-focused portfolio. A 65-year-old who's already retired needs stability and might choose mostly bonds and money market funds. A 45-year-old might split the difference with a balanced fund.

Your provider doesn't earn money from your investment returns—they earn money from account fees (if any) and from the spreads on trades. This is why some providers charge nothing to open or maintain a Roth IRA: they make money on volume and on the small difference between what they pay for investments and what they charge you. This also means your provider has no incentive to steer you toward high-return investments; they profit the same whether you earn 3% or 10%.

Fixed-rate options: CDs inside a Roth IRA

Some Roth IRA providers let you invest in certificates of deposit (CDs), which do pay a fixed interest rate. A CD is a promise: you give the bank money for a set period—three months, one year, five years—and the bank pays you a may provide rate. Right now, a five-year CD might pay 4.5% to 5%. You know exactly what you'll earn. The tradeoff is that you can't access the money without a penalty, and the rate is usually lower than what you could earn in a diversified stock portfolio over the same period.

A Roth IRA CD works the same way as a regular CD, except the growth is tax-free and you can't withdraw before age 59½ without a penalty (with some exceptions). Some people use CDs for part of their Roth IRA—say, the portion they'll need in the next five years—and stock funds for the rest. This gives them some may provide returns and some growth potential.

How fees affect what you actually earn

Two Roth IRAs invested in the same stock fund can produce different returns if one charges higher fees. A fund with a 0.05% annual expense ratio costs you $5 per year on a $10,000 balance. A fund with a 1% expense ratio costs you $100 per year on the same balance. Over 30 years, that difference compounds dramatically. The lower-fee fund could leave you with tens of thousands of dollars more.

Most major brokerages (Vanguard, Fidelity, Charles Schwab, Schwab US Bank) offer low-cost index funds with expense ratios under 0.20%. Some offer funds with ratios under 0.05%. Avoid funds charging 1% or more unless there's a specific reason—and there usually isn't. The easiest way to keep fees low is to invest in broad index funds rather than actively managed funds, which charge more because someone is supposedly picking stocks for you.

What you can control and what you can't

You can't control what the stock market does. You can't control interest rates or inflation. You can't control whether a company you own stock in has a good year or a bad year. What you can control is what you invest in, how much you pay in fees, and how long you hold it. You can choose a diversified portfolio instead of betting on individual stocks. You can choose low-cost index funds instead of expensive actively managed funds. You can commit to not selling in a panic when the market drops.

The most important control you have is time. A Roth IRA is designed for long-term growth. Money you won't touch for 20 or 30 years can weather market downturns because there's time to recover. Money you might need in five years should be in something safer, even if it earns less. Your age, your other savings, and your actual timeline matter more to your return than any specific fund choice.

Frequently Asked Questions

Can I get a may provide return in a Roth IRA?

Yes, through CDs or money market funds. A CD guarantees a specific rate for a set period. A money market fund doesn't may provide a rate, but it's very stable and currently pays around 4% to 5%. Both are safer than stocks but typically earn less over long periods.

What's a realistic return to expect from a Roth IRA?

If you invest in a diversified portfolio of stocks and bonds, expect 5% to 8% annually over long periods. Some years will be much higher, some much lower. If you invest mostly in bonds or money market funds, expect 3% to 5%. These are historical averages, not guarantees.

Do I need to pick individual stocks to get good returns?

No. Most individual investors do worse than index funds because picking individual stocks is hard and fees add up. A simple portfolio of two or three low-cost index funds—one for U.S. stocks, one for international stocks, one for bonds—historically outperforms most people who try to pick winners.

What happens if my Roth IRA loses money?

You don't owe anything. Losses stay inside the account. If you invested $5,000 and it dropped to $4,500, you've lost $500, but you haven't triggered a tax bill or a penalty. You can leave it there to recover, move it to a different investment, or do nothing. The loss is only permanent if you sell.

Does the bank pay interest on the cash sitting in my Roth IRA?

Most brokerages sweep uninvested cash into a money market fund that pays current interest rates, usually 4% to 5%. Some older accounts might leave cash earning nothing. Check your account settings; you can usually move idle cash into a money market fund yourself if it's not automatic.
