Convert APR to APY
This conversion assumes a nominal APR with regular compounding and no additional fees.
Formula: APY = (1 + APR/n)^n β 1
Keep the interest rate, payment frequency and time period consistent. Fees, compounding rules, taxes and lender or issuer conventions can change a real-world result, so use the calculator as a calculation aid rather than a contract quote.
Recalculate the result from the displayed formula and confirm that rate, term, compounding and monetary amounts use the same time basis.
