APR vs. APY Calculator

How this calculator works

APR-to-APY compounds the periodic nominal rate. APY-to-APR reverses that relationship for the selected number of compounding periods.

Change one assumption at a time to see which inputs have the greatest effect on the estimate.

Worked example

A 12% nominal APR compounded monthly produces an APY above 12%.

Limitations

Fees, timing, day-count conventions, and continuously compounded products can make advertised rates differ. Editorial review is required before publication.
