About APR Calculator

APR Calculator estimates the real annual percentage rate for both standard loans and mortgages. The mortgage mode uses the home value, down payment, lender fees, points, and optional PMI to estimate a more realistic mortgage APR.

How To Use It

Choose the APR type that matches your financing, enter the required values, and compare the total cost shown in the result table.

Use General APR for personal, auto, or business loans where you know the borrowed amount, compounding pattern, payment frequency, and fees.
Use Mortgage APR when you want the calculation to include house value, down payment, discount points, loan fees, and optional PMI.
Review the real APR together with the payment totals so you can compare quoted rates against the true borrowing cost.
