Annual percentage rate (APR). In the context of credit cards, the periodic rate times the number of periods in a year. For example, a 1.5% monthly rate has an APR of 18%. In the context of consumer lending, the APR takes into account more than the interest rate applied to the principal per period.ignificantly, the APR does not account for compounding. For example, if the APR is 36%, the percentage is 3% per month, but the interest rate or cost of funds for the entire year may be greater than 36% due to the effects of compounding.
