What is APR (Annual Percentage Rate)?

APR represents the true yearly cost of borrowing money. It includes not only the interest rate, but also most mandatory fees associated with the loan.

This makes APR a better comparison tool than the base interest rate alone. Two loans can have the same interest rate but different APRs if their fees differ.

APR vs Interest Rate

The interest rate is the basic cost of borrowing. APR adds fees and gives a more complete view of the real loan cost.

APR = annualized borrowing cost
Monthly payment = loan amortization equation
Total paid = monthly payment × months
Total interest = total paid − loan amount
