Yes, most HSA accounts earn interest, but the rate depends on how your account is set up

An HSA can earn interest the same way a savings account does — your money sits in the account, the bank pays you a small percentage of it each month or quarter, and that interest gets added to your balance. Whether yours actually earns interest depends on two things: whether your HSA provider offers an interest-bearing option, and whether you choose it when you open the account.

Many people with HSAs never see interest because their money sits in a non-interest-bearing account by default. This is like keeping cash in a checking account that pays nothing. You can usually switch to an interest-bearing version, but you have to ask for it or select it during setup. The interest rates vary widely — some accounts pay less than 0.01 percent, while others pay closer to 4 or 5 percent, depending on current market conditions and your provider.

The catch is that interest-bearing HSA accounts often come with monthly fees or minimum balance requirements. A $3 monthly fee can wipe out the interest you earn on a small balance, so the math only works in your favor if you have enough money sitting in the account to make the interest meaningful.

Key Takeaways

  • HSA accounts can earn interest, but many are set up as non-interest-bearing by default, so you need to request or select an interest option when opening the account.
  • Interest rates on HSAs vary from nearly zero to around 4 or 5 percent depending on your provider and current market rates.
  • Interest-bearing HSA accounts often charge monthly fees or require a minimum balance, which can cost more than the interest you earn if your balance is small.
  • Some HSA providers let you keep part of your money in an interest-bearing savings portion and invest the rest in mutual funds or stocks for potentially higher returns.

How interest gets added to your HSA

When an HSA earns interest, the bank calculates it based on your account balance and the interest rate they offer. If your account has $5,000 and the bank pays 2 percent annual interest, you would earn roughly $100 per year (though it is usually paid monthly in smaller chunks). That interest is deposited directly into your HSA, increasing your balance.

The interest accrues whether you use the money or not. If you leave $5,000 untouched for a year, you earn interest on the full $5,000. If you withdraw $2,000 for a medical expense, the next month's interest is calculated on the remaining $3,000. Interest is always calculated on whatever balance you currently have.

When interest-bearing accounts make financial sense

An interest-bearing HSA is worth the effort if you have a balance large enough that the interest outweighs any monthly fees. If your provider charges $3 per month and pays 1 percent annual interest, you need roughly $3,600 in the account for the interest to break even with the fee. Below that, you lose money. Above it, you gain.

Interest-bearing accounts make the most sense if you are using your HSA as a long-term savings tool rather than spending it when ready on medical bills. Many people with good health and low medical expenses keep their HSA balance growing year after year. For those people, even a small interest rate adds up over time.

If you use your HSA to pay medical bills as they come in and keep a low balance, a non-interest-bearing account is probably fine. The interest you would earn on a small balance is unlikely to cover the monthly fee.

HSA investments as an alternative to interest

Some HSA providers offer a second option beyond interest: you can invest your HSA balance in mutual funds, index funds, or other investments. This is different from interest. Instead of the bank paying you a set percentage, you own a piece of an investment that may go up or down in value.

Investments can earn more than interest over time, but they also carry risk. A mutual fund might return 7 percent in a good year and lose 5 percent in a bad year. Interest is may provide and stable — you know exactly what you will earn. Many HSA providers let you split your balance: keep some in an interest-bearing account and invest the rest.

If you are young and do not plan to use your HSA for many years, investing can make sense because you have time to ride out market ups and downs. If you might need the money soon, keeping it in an interest-bearing account or a non-interest-bearing account is safer.

How to learn about your HSA earns interest

Check your HSA provider's website or call the customer service number on the back of your HSA card. Ask whether your account is currently interest-bearing and what the current rate is. If it is not, ask whether you can switch to an interest-bearing version and what the fees are.

Your HSA provider is usually a bank or a financial company hired by your employer's health plan. The name appears on your account statements and on any paperwork you received when the account opened. If you are not sure who your provider is, check your health plan's website or call your employer's benefits department.

When you contact them, also ask about investment options if you have a larger balance and a longer time horizon. Some providers make this information hard to find, but customer service can walk you through what is available.

Interest rates change with the market

HSA interest rates are not fixed. They move up and down based on what banks are paying on savings accounts generally. When the Federal Reserve raises interest rates, HSA rates usually go up. When rates fall, HSA rates fall too. This means the rate you see today might be different in six months.

Some providers adjust rates monthly, others quarterly. A few lock in a rate for a set period. Check your account statements or log into your provider's website to see your current rate. If you see it has dropped significantly, it might be worth comparing to other HSA providers, though switching accounts involves paperwork and takes time.

Frequently Asked Questions

Can I move my HSA to a different provider if I want a higher interest rate?

Yes. You can request a direct transfer (called a trustee-to-trustee transfer) from your current HSA provider to a new one. The money moves directly between accounts without you touching it, so there are no tax consequences. The process usually takes one to two weeks. Your new provider will handle most of the paperwork.

Does the interest I earn on my HSA count as income for taxes?

No. Interest earned in an HSA is not taxable income. This is one of the tax advantages of HSAs. The interest stays in the account and grows tax-free, just like the contributions you make.

What happens to interest if I use my HSA money for a non-medical expense?

The interest itself is not affected. If you withdraw money for a non-medical expense, you owe income tax on the withdrawal plus a 20 percent penalty (in most cases). The interest you earned is treated the same way as the original money — it is subject to tax and penalty if withdrawn for non-medical reasons.

Is it better to invest my HSA or keep it in an interest-bearing account?

It depends on your timeline and comfort with risk. Investments can earn more over decades, but they fluctuate in value. Interest is lower but may provide and stable. If you might need the money within five years, interest-bearing is safer. If you are saving for retirement and do not plan to touch it, investing may make sense.

Do all HSA providers offer interest-bearing accounts?

Most do, but not all. Some smaller providers or employer-sponsored plans may only offer non-interest-bearing accounts. If your current provider does not offer interest, you can switch to one that does through a trustee-to-trustee transfer.
