APY & Compounding Calculator

Convert an APR into its compounded APY and project how a position grows over time at any compounding frequency.

APR vs APY

APY = (1 + APR/n)ⁿ − 1, where n is compounds per year. A 50% APR compounded daily is a 64.8% APY; the gap widens fast at DeFi-sized rates, which is why quoting conventions matter.

Project your position

Set an amount, rate, compounding frequency and horizon to see the growth curve — useful for comparing auto-compounding vaults against manual claiming once gas enters the picture.
