How to Calculate Interest Earned from HSA | HSA Savings Account Tips

If you have a Health Savings Account (HSA), you may be curious about how to calculate the interest earned on your savings. An HSA is a tax-advantaged account that allows individuals to save for qualified medical expenses. One of the benefits of having an HSA is the potential to earn interest on your contributions. Let's dive into how you can calculate the interest earned from your HSA.

Interest on an HSA is typically calculated daily and paid out monthly or quarterly depending on the financial institution holding your account. To calculate the interest earned on your HSA, you can use the following formula:

Interest Earned = (Principal Amount x Annual Interest Rate x Number of Days) / 365

Here's a breakdown of the steps involved in calculating the interest earned from your HSA:

  • Determine the principal amount in your HSA, which is the total balance in your account.
  • Find out the annual interest rate on your HSA, which can vary depending on the financial institution.
  • Count the number of days the money has been in your account since the last interest payout.
  • Plug these values into the formula mentioned above to calculate the interest earned.

It's important to note that the interest earned on an HSA is considered tax-free as long as the funds are used for qualified medical expenses. Additionally, some HSAs may offer tiered interest rates based on the account balance, so be sure to check with your provider for specific details.

By understanding how interest is calculated on your HSA, you can make informed decisions about your healthcare savings and maximize the benefits of your account. Keep track of your contributions, interest earned, and expenses to ensure you are utilizing your HSA to its fullest potential.


Calculating the interest earned on your Health Savings Account (HSA) not only gives you insight into your savings but also helps you maximize your financial strategy. Remember, the interest can compound over time, potentially yielding greater returns.
