APR Calculator
Calculate the Annual Percentage Rate (APR) including fees and charges on a loan.
Why APR matters
APR includes fees and charges, giving you the true cost of a loan. Two loans with the same interest rate can have different APRs if the fees differ. Always compare APRs, not just interest rates.
What is APR Calculator?
Annual Percentage Rate (APR) is the yearly cost of borrowing, including the interest rate and any fees charged by the lender. An APR calculator shows the true cost of a loan.
APR helps you compare loans from different lenders on a like-for-like basis, because it includes fees that the headline rate ignores.
How does the APR Calculator work?
The calculator adds all fees to the total interest, divides by the loan amount and term, and annualizes the result.
A more precise APR is computed by solving for the rate that makes the present value of all payments equal to the loan amount.

Frequently Asked Questions
Why is APR higher than the interest rate?
APR includes fees and other charges on top of the interest rate, so it is usually higher.
