Interest is modeled using the monthly rate equivalent to the entered APY, with monthly deposits added after that month’s interest.
How to Use the HYSA Interest Calculator
Enter your starting balance, the account APY, monthly deposits and savings horizon. The calculator estimates your ending balance, total deposits and interest earned. Use the comparison APY to see how a different rate could affect the same savings plan.
Why APY Matters
APY includes the effect of compounding over a year, making it useful for comparing savings accounts. Rates are typically variable, so actual interest earned can be higher or lower than this illustration.
