How to calculate high-yield savings growth

  1. Enter your balance. Add your starting balance and any monthly deposit.
  2. Enter the APY. Use the account’s advertised APY and the number of years.
  3. Compare the growth. See the future balance and the interest the higher rate earns.

Why the APY matters

An emergency fund or short-term savings sitting in a low-rate account quietly loses ground to inflation; a higher APY narrows the gap. If you can lock the money away, compare against a CD, and convert any APR quote with the APY calculator.

Educational tool only — not financial advice. Rates change and interest is generally taxable; figures are pre-tax estimates.

Frequently asked questions

What is a high-yield savings account?
A high-yield savings account (HYSA) pays a much higher APY than a typical bank savings account — often several percent — while keeping your money liquid and, at US banks, FDIC-insured. This tool shows what your balance grows to at that higher rate.
What’s the difference between APR and APY?
APY already includes the effect of compounding, so it’s the figure to compare savings accounts by. Enter the account’s advertised APY here.
How much more does a higher APY earn?
Try changing the APY and watch the interest figure — the gap between, say, 0.5% and 4.5% compounds into a large difference over years, especially with regular deposits.
Does this include tax?
No — savings interest is generally taxable; the figures are pre-tax. Use the inflation calculator to see real (after-inflation) value.
Is my data sent anywhere?
No — it computes in your browser.
