APR Calculator

By the CalcMundi team · Updated October 22, 2026 · Formulas checked against standard financial math

Enter the amount you receive, the monthly payment and the number of payments to see the APR.

What the APR is

The annual percentage rate includes the interest and the fees of the loan, such as an origination fee. Under the Truth in Lending Act, lenders must show the APR before you sign. Compare APRs, not just interest rates.

Example

You receive $10,000 and pay 36 payments of $330: the APR is about 11.55% (0.96% a month), and you pay back $11,880 in total.

Frequently asked questions

Why is the APR higher than the interest rate?

Because it includes the fees. If a $500 fee is taken out of the loan, you receive less money but pay the same installments.
