Step 1
Understand APR (Annual Percentage Rate). APR is a calculation used to determine the annual percentage rate of interest you will pay for a line of credit or loan. APR is applied to credit cards, auto loans, mortgage loans and other lines of credit.
-
Step 2
Do the math. A loan with a 5 percent APR means the debtor will pay $5 for every $100 owed per year. A loan with a 25 percent APR will yield $25 in interest for every $100 owed for the year.

Step 3
Use an online APR calculator or financial calculator for easy calculation. According to the Capital One online calculator (see Resources), a $10,000 loan with a 5.99 percent APR and 12-month term will yield a cumulative interest amount of $327.42. The cumulative amount paid on the loan after the 12-month term will be $10,327.42.
-
Step 4
Use a simple equation to calculate the APR on a loan. Using the above example, multiply $10,000 (the loan amount) by 5.99 (the interest rate) divided by 12 (the term of the loan) to reach the APR amount: 10,000 X 5.99 / 12 = $49.92 (APR)
