Calculate Annual Percentage Yield (APY) from any APR and compounding frequency. Find out how much compound interest you'll earn on savings accounts, CDs, and high-yield savings accounts over any period.
APR (Annual Percentage Rate) is the stated interest rate before compounding. APY (Annual Percentage Yield) is the effective annual rate after compounding is applied — it's always higher than APR (except when compounding is annual). The more frequently interest compounds, the bigger the gap between APR and APY.
APY = (1 + APR ÷ n)ⁿ − 1
Where n is the number of compounding periods per year.
