Question: how to calculate annual percentage rate on credit cards?
Answer: Divide your card's annual percentage rate (APR) to get the periodic rate. If your issuer uses a daily balance, divide the APR by 365. If the APR is compounded monthly, divide it by 12. For example, an APR of 14.99% compounded daily would have a periodic rate of (14.99% / 365) = 0.0004 = 0.04%.
