APY Calculator
Calculate annual percentage yield to compare savings or investment returns when interest compounds during the year. 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 + r/n)^n β 1.
A useful way to check it
Use the calculator as a quick verification tool as well as a way to get the final number. Understanding what the result represents is just as important as the number itself. 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.
