Yes, HSA accounts earn interest, but the rate depends on how your account is set up and where the money sits

Most HSA accounts do earn interest, though the amount varies widely. If your HSA is held at a bank or credit union, it typically earns interest the same way a savings account does—usually between 0.01% and 5% annually, depending on current rates and the institution. If your HSA is held at an investment firm or through your employer's plan, you may have the option to invest the money in mutual funds or other securities, which can earn more but also carry risk. The catch: money in a money market fund or savings feature earns interest; money sitting in a non-interest-bearing cash account earns nothing.

The interest you earn is yours to keep and does not count against your annual contribution limit. It also does not affect your taxes—interest earned in an HSA is tax-free, just like the contributions themselves.

Key Takeaways

  • HSA accounts held at banks or credit unions typically earn interest between 0.01% and 5% per year, depending on the institution and current market rates.
  • Some HSAs allow you to invest in mutual funds or stocks, which may earn more than interest but come with investment risk.
  • Interest earned in your HSA is tax-free and does not reduce your contribution room for the year.
  • Money sitting in a non-interest-bearing cash sweep account earns nothing, so ask your HSA provider whether your balance is automatically earning interest.
  • HSA interest rates and investment options vary by provider, so comparing your options before opening an account can make a real difference over time.

How interest rates work on HSA savings features

When you open an HSA at a bank or credit union, your money typically goes into a savings account or money market account that earns interest. The rate is set by the institution and changes with market conditions. Right now, some banks offer rates around 4% to 5% on HSA savings accounts, while others offer much less—sometimes under 0.5%. The rate you get depends on which bank or credit union holds your account.

Interest accrues daily or monthly, depending on the provider, and is added to your account balance. You do not have to do anything to earn it—the interest is automatic. However, some HSA providers keep your money in a non-interest-bearing account by default and require you to move it to a savings feature yourself. Check with your provider to confirm where your balance is sitting.

Investment options for larger HSA balances

If you have a substantial balance in your HSA, some providers let you invest the money in mutual funds, index funds, or other securities. This is different from interest-bearing savings: instead of earning a fixed rate, your money grows (or shrinks) based on how the investments perform. Over long periods, stock-based investments have historically returned more than savings account interest, but they also carry the risk of losing value in the short term.

Most HSA providers that offer investment options require you to keep a minimum balance—often $1,000 to $2,500—in the savings feature before you can invest the rest. This protects you from having to sell investments at a loss just to pay a medical bill. If you are young and do not plan to use your HSA for several years, investing can make sense. If you expect to use the money soon, keeping it in a savings account is safer.

Comparing HSA providers to find better interest rates

Because interest rates and investment options vary so much between providers, the HSA you choose can affect how much your money grows. A provider offering 4% interest will earn you significantly more than one offering 0.1%, especially if you carry a balance year to year. Some employers offer HSAs through specific providers, which limits your choice, but if you have options, it is worth comparing.

When comparing, look for: the interest rate on the savings feature, whether there are monthly or annual fees that eat into earnings, whether you can invest part of your balance, and how easy it is to move money between the savings account and investments. A provider with a slightly lower interest rate but no fees may actually earn you more than one with a high rate and high costs.

What happens to interest if you change HSA providers

If you switch HSA providers, the interest you have already earned stays in your account and moves with you. When you roll over or transfer your HSA balance to a new provider, all the money—including accrued interest—transfers as well. You do not lose the interest, and you do not owe taxes on it.

However, you may lose interest during the transfer itself. Some transfers take a few days, and if your old provider stops paying interest the moment you initiate the transfer, you may miss a few days of earnings. This is usually a small amount, but it is worth asking your new provider about their timeline.

How HSA interest affects your taxes

Interest earned in an HSA is not taxable income. You do not report it on your tax return, and it does not reduce your contribution limit for the year. This is one of the major advantages of an HSA: all the growth—whether from interest or investments—is tax-free as long as the money is used for may have access to medical expenses.

If you withdraw money from your HSA for a non-medical expense before age 65, you owe income tax on the withdrawal plus a 20% penalty. The interest you earned is part of that withdrawal, so it is also subject to tax and penalty if the withdrawal is not for a may have access to expense. After age 65, you can withdraw money for any reason without the penalty, though you still owe income tax on non-medical withdrawals.

Strategies to maximize HSA interest earnings

If you want your HSA to grow as much as possible, keep money in it longer rather than spending it immediately. The longer your balance sits earning interest or growing through investments, the more it compounds. Some people use their HSA as a retirement savings tool: they pay medical expenses out of pocket and let the HSA balance grow untouched until retirement, when they can withdraw it for any reason without penalty (though they still owe tax on non-medical withdrawals).

Another strategy is to choose a provider with a high interest rate and low fees, especially if you plan to keep a large balance. Over 10 or 20 years, the difference between a 0.5% rate and a 4% rate can add up to thousands of dollars. If your employer offers multiple HSA options, compare them before enrolling. If you have already enrolled and your provider's rate is low, you can switch to a better one during your employer's open enrollment period or at any time if you have an individual HSA.

Frequently Asked Questions

Do I have to do anything to earn interest on my HSA?

No, if your HSA is in a savings account or money market account, interest accrues automatically. However, some providers keep your money in a non-interest-bearing account by default, so you may need to move it to a savings feature yourself. Contact your HSA provider to confirm where your balance is earning interest.

Can I lose money in an HSA if I invest it?

Yes, if you invest your HSA balance in stocks or mutual funds, the value can go down as well as up. This is why most providers require you to keep a minimum balance in the savings account before investing the rest—so you have money available for medical expenses without having to sell investments at a loss.

What is the difference between HSA interest and HSA investments?

Interest is a fixed rate paid by the bank or credit union holding your account, usually between 0.01% and 5% per year. Investments are mutual funds or stocks that grow or shrink based on market performance. Interest is safer but earns less; investments can earn more but carry risk.

Does HSA interest count toward my contribution limit?

No, interest earned in your HSA does not count toward your annual contribution limit. You can contribute up to the limit set by the IRS each year, and any interest you earn is on top of that.

What happens to my HSA interest if I leave my job?

Your HSA and all the interest you have earned belong to you, not your employer. When you leave your job, you can keep the account open, roll it over to a new provider, or transfer it to an individual HSA. The interest stays with the money.
