APR to APY Calculator
Convert an annual percentage rate to an annual percentage yield when periodic compounding is known. It can make a financial figure easier to understand before you compare options or enter the numbers into a larger budget.
How to use this calculator
Enter the starting amount and the rate or time values requested. Check whether the rate is annual and whether compounding or contributions are included before comparing the result with another estimate.
Formula
APY = (1 + APR/n)^n β 1 when APR is a nominal annual rate compounded n times per year.
A useful way to check it
Where a rate, percentage, or time period is involved, confirm that it matches the period used by the formula. Financial results can change with rates, fees, taxes, dates, and the assumptions entered. Treat the figure as an estimate and verify important numbers against the terms that actually apply.
