APY Calculator

Convert a nominal annual rate and compounding frequency into annual percentage yield.

Annual percentage yield

How it works

APY is the nominal rate compounded over a year, so the same rate yields more as compounding grows more frequent.

Example

4.9% compounded monthly is an APY of about 5.01%, worth roughly $501 on $10,000.
