Yes, HSA accounts earn interest, but the rate depends on how your account is structured and where you keep the money

Most HSA accounts do earn interest, though the amount varies widely. Your HSA can work like a savings account at a bank or credit union, where deposits sit in an interest-bearing account. Some HSAs are held at investment firms and allow you to buy stocks, bonds, or mutual funds instead. A few HSAs are bare-bones accounts with no interest at all — these typically charge monthly fees and hold cash with no growth.

The interest rate you earn depends on three things: which financial institution holds your account, what type of account structure they offer, and how much money you keep in it. A bank HSA might earn 4 to 5 percent annually on cash balances right now, while a money market fund inside an HSA might earn slightly less but with less risk than stocks. An investment-focused HSA earns whatever return the stocks or bonds inside it generate — which could be positive or negative.

The catch is that you have to choose. Your employer or HSA provider sets up the account, but you often control where the money sits. Moving money from a non-interest account to an interest-bearing one usually takes a few clicks online, though some older HSA plans make it harder.

Key Takeaways

  • HSA accounts held at banks or credit unions typically earn interest rates between 4 and 5 percent on cash balances, though rates change with the broader economy.
  • Investment-based HSAs let you buy stocks, bonds, or funds, which can grow faster than interest but also carry the risk of losing value.
  • Some HSA providers charge monthly maintenance fees that can eat into or exceed the interest you earn, so compare the full cost before choosing where to keep your money.
  • You can move your HSA to a different financial institution if your current provider's interest rate or fees are not competitive, though the process takes one to two weeks.
  • The interest you earn on an HSA is not taxed, which makes HSA growth more efficient than earning interest in a regular savings account.

How interest rates work on HSA cash balances

When your HSA sits in a savings account at a bank or credit union, the institution pays you interest on the balance you hold. That rate is set by the bank and changes based on what the Federal Reserve does with interest rates. Right now, some banks offer 4 to 5 percent annual percentage yield (APY) on HSA savings accounts, though this varies by institution and can shift monthly.

The interest accrues daily and is usually added to your account monthly. If you have $5,000 in an HSA earning 4.5 percent APY, you earn roughly $225 per year, or about $18.75 per month. That money stays in your HSA and can be used for medical expenses just like the original deposit.

Not all HSA providers offer the same rate. Some credit unions offer higher rates than national banks. Some online banks offer rates competitive with the highest available. Your employer's HSA provider may have negotiated a lower rate with their bank partner. The only way to know what you are earning is to log into your account and check, or call the provider directly.

Investment options inside HSAs and how they grow

Many HSA providers let you move money beyond a cash account into an investment account. This usually means you can buy mutual funds, exchange-traded funds (ETFs), stocks, or bonds. The growth you earn depends entirely on what those investments do — if the stock market rises, your HSA grows; if it falls, your HSA shrinks.

Investment-based HSAs are useful if you do not plan to spend the money on medical expenses soon. Someone in their 30s or 40s with low medical costs might invest HSA money for decades, letting it compound like a retirement account. Someone who uses their HSA every year for prescriptions and doctor visits would keep most of the money in the cash account instead.

The tradeoff is volatility. A money market fund inside an HSA might earn 4 to 5 percent with almost no risk of losing value. A stock index fund might earn 8 to 10 percent in a good year but could lose 15 to 20 percent in a bad year. You choose the risk level that matches your timeline and comfort.

Fees that reduce or eliminate interest earnings

Some HSA providers charge monthly maintenance fees, inactivity fees, or investment management fees. These fees can be $2 to $5 per month for basic accounts, or higher if you are paying for professional investment management. If your account earns $3 per month in interest but costs $4 per month in fees, you are losing money.

Employer-sponsored HSAs sometimes have lower fees because the employer negotiates on behalf of all employees. Individual HSAs opened outside an employer plan often have higher fees. Before you move your HSA or choose a provider, ask directly: What are all the fees? What is the current interest rate? Is there a minimum balance to earn interest?

Some providers waive fees if you maintain a certain balance — often $1,000 or $2,500. Others charge fees regardless. Reading the fee schedule matters more than the advertised interest rate, because a 4.5 percent rate minus $5 per month in fees is worse than a 3.5 percent rate with no fees.

Moving your HSA to earn a better rate

You can move your HSA from one financial institution to another if you find a better interest rate or lower fees. This is called a trustee-to-trustee transfer. The money moves directly from your old HSA to your new one without touching your hands, so there are no tax consequences and no contribution limits triggered.

The process usually takes one to two weeks. You contact the new HSA provider, fill out a transfer form, and they handle the rest. Your old provider sends the balance to the new one. During the transfer, your money sits in transit and earns nothing, but this is usually only a few days.

You can do a trustee-to-trustee transfer as often as you want. Some people move their HSA annually to chase the highest interest rate. Others move it once and stay put. There is no penalty or limit on how many times you transfer, though some providers may charge a small transfer fee (usually $0 to $25).

Tax advantages of HSA interest and investment growth

Interest earned in an HSA is not taxed as income. If you earn $200 in interest on your HSA, you do not report that $200 on your tax return. This is different from a regular savings account, where interest counts as taxable income.

Investment gains inside an HSA are also not taxed. If you buy a mutual fund for $5,000 and it grows to $6,500, that $1,500 gain is not taxed when it happens. You only pay taxes if you withdraw money for something other than a may have access to medical expense — and even then, you only pay taxes on the gains, not the original contribution.

This tax-free growth is one reason HSAs are powerful long-term accounts. Over 20 or 30 years, the difference between tax-free growth and taxable growth compounds significantly. A $3,000 annual HSA contribution earning 5 percent per year grows to roughly $150,000 after 30 years if left untouched. That same money in a taxable account would be smaller because of annual tax bills.

Comparing HSA interest to other savings options

A high-yield savings account at a bank currently earns similar rates to an HSA savings account — often 4 to 5 percent. The difference is that HSA interest is tax-free, while savings account interest is taxed as income. If you are in the 24 percent tax bracket, a 4.5 percent taxable rate is equivalent to a 3.4 percent after-tax rate. An HSA earning 4.5 percent stays 4.5 percent after tax.

Money market accounts and certificates of deposit (CDs) also earn similar rates to HSAs. The advantage of an HSA is that you can withdraw the money anytime for medical expenses without penalty, whereas a CD locks your money for a set term.

If you do not have an HSA, you cannot get the tax advantage no matter what rate you find. An HSA is only available if you are enrolled in a high-deductible health plan (HDHP). If you have access to one and do not use it, you are leaving tax-free growth on the table.

Frequently Asked Questions

What is the typical interest rate on an HSA right now?

Interest rates on HSA savings accounts range from 4 to 5 percent annually, though this varies by provider and changes as the Federal Reserve adjusts rates. Check your specific provider's website or call them directly to see what rate you are earning. Some providers offer lower rates if you have a small balance or do not meet minimum requirements.

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

Yes, if you invest HSA money in stocks or stock-based funds, the value can go down. If you buy a fund worth $5,000 and the market falls, it might be worth $4,200. You only lose money if you sell while the price is down. Money kept in a cash savings account does not fluctuate — it only grows by the interest rate.

Do I have to pay taxes on HSA interest?

No. Interest earned in an HSA is not taxed as income, and investment gains inside an HSA are not taxed either. This is one of the main advantages of using an HSA instead of a regular savings account. Taxes only explore if you withdraw money for non-medical expenses.

How often can I move my HSA to a different bank?

You can move your HSA as often as you want using a trustee-to-trustee transfer. There is no limit on how many times you transfer, though the process takes one to two weeks each time. Some providers charge a small transfer fee, usually $0 to $25.

Should I invest my HSA or keep it in savings?

That depends on when you plan to use the money. If you use your HSA every year for medical expenses, keep most of it in a savings account earning interest. If you have low medical costs and do not plan to touch the money for years, investing in a diversified fund can generate higher long-term growth. Many people split the difference: keep one year of expected medical expenses in savings, and invest the rest.
