About this calculator

A loan calculator turns a loan amount, interest rate (APR) and term into a fixed monthly payment and shows how much interest you pay in total. It works for personal loans, car loans, student loans and any other amortizing loan.

Frequently asked questions

What is APR?

APR (annual percentage rate) is the yearly cost of a loan including interest. This calculator uses it as the nominal annual rate, compounded monthly.

Is my real payment exactly this?

It is an accurate estimate for a standard fixed-rate amortizing loan. Your lender may add fees, insurance or a different rounding, so confirm with them.
