How to Use the Payment Calculator

Enter the loan amount, annual interest rate, and term in years — that's the whole tool. One result, no modes, no schedule.

Sometimes the payment number is genuinely all you need. This calculator skips the schedule and the toggles and just answers: what would this loan cost per month?

M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]

P is the loan amount, r the monthly interest rate (annual rate ÷ 12), and n the total number of monthly payments. Total Interest and Total Cost sit next to the payment so the full cost of borrowing is visible at a glance, not just the monthly bite.

That makes it a good fit for a quick sanity check — punch in the numbers from a loan estimate or a dealer quote and see whether the payment they quoted actually matches the math.

This is the fast version — for the full year-by-year schedule or a solver that works backward from a target payment, the site's Amortization Calculator and Loan Calculator cover that ground instead.
