What Is the Difference Between APR and APY?
APR to APY Calculator is a free online tool that convert between APR and APY with different compounding frequencies. See real earnings on $1,000. No files are uploaded — everything is processed locally on your device.
An APR to APY calculator converts between annual percentage rate and annual percentage yield, accounting for the effect of compounding. APR represents the simple annual interest rate without compounding, while APY reflects the actual return you earn when interest compounds on itself over the year. In DeFi and crypto staking, protocols often advertise APR, but your real earnings depend on how frequently rewards compound. Our calculator converts in both directions, supports multiple compounding frequencies, and previews your projected earnings — all processed privately in your browser.

Frequently Asked Questions
What is the difference between APR and APY?
APR is the simple annual rate without compounding. APY includes the effect of compounding interest on interest. APY is always equal to or higher than APR for the same nominal rate.
Why is APY higher than APR?
APY accounts for compound interest — you earn returns on your previously earned returns. The more frequently compounding occurs, the larger the gap between APY and the equivalent APR.
Does compounding frequency matter?
Yes. Daily compounding yields more than monthly, which yields more than annual compounding for the same APR. In DeFi, many protocols auto-compound daily, making the frequency very relevant.
Is this calculator free to use?
Yes. The calculator is completely free with no limits. All conversions run instantly in your browser and no financial data is collected, stored, or transmitted.
