The formula

APY = (1 + APR ÷ n)n − 1, where n is the number of compounding periods a year. A 5% APR compounded monthly is a 5.116% APY; compounded daily it is 5.127%.

Why both exist

US rules require banks to quote APY on savings accounts (Truth in Savings Act, Regulation DD) and lenders to quote APR on loans (Truth in Lending Act, Regulation Z). APR on a loan also includes some fees, so it can be higher than the note rate.
