About the APY Calculator
APY (Annual Percentage Yield) reflects the true annual return on savings once the effect of compounding is included, so it's always equal to or higher than the stated nominal rate.
Formula: APY = [(1 + r/n)n − 1] × 100, where r is the nominal annual rate and n is the number of compounding periods per year.
Comparing APY, rather than nominal rates, is the fairest way to shop between savings accounts and CDs that compound on different schedules.
