APY Calculator — Annual Percentage Yield
Annual Percentage Yield (APY) is the real rate of return on a savings account, taking into account the effect of compounding interest. Unlike the nominal interest rate, APY reflects how often interest is compounded — daily, monthly, or annually — giving you a true picture of what your savings will earn. Our APY calculator lets you compare savings accounts with different compounding frequencies so you can choose the account that gives you the best real return. A higher compounding frequency means your money grows faster, even if the nominal rate is the same.
