When to use Loan Calculator

You're at the car dealership and the finance manager is about to walk you through a 72-month loan at 7.9% APR. Before you nod, pull up this page: enter the sticker price minus your trade-in, the rate, and the term. The amortization formula (M = P[r(1+r)^n] / [(1+r)^n - 1]) gives you the monthly payment in seconds — and the full schedule shows exactly how much of each payment goes to interest versus principal over the life of the loan. In month 1 of a 72-month loan, the majority goes to the lender, not the car. Useful for comparing a 48-month versus 60-month term side by side before signing. Your numbers never leave the browser.

  • Compare a 48-month vs 60-month car loan before signing
  • See how much total interest a personal loan will cost
  • Verify a student loan monthly payment against a lender quote

About this tool

What will this loan actually cost you over its full term? Enter the principal, annual interest rate, and loan length to see your monthly payment, total interest paid, and a complete amortization schedule — the month-by-month breakdown of how each payment splits between principal and interest. Early in a loan, most of the payment goes to interest; the schedule makes that concrete. Works for car loans, personal loans, student loans, or any fixed-rate debt. Pure computation — no AI involved. Your financial details never leave your browser.

Frequently asked

How is the monthly payment calculated?
The payment schedule uses the standard amortization formula — principal multiplied by the monthly rate and a compounding factor, divided by the same compounding factor minus one. Enter your principal, APR, and term and the browser computes the full schedule without a server call.
Does this tool support different loan types?
This calculator uses a fixed-rate amortization schedule. It works for mortgages, car loans, personal loans, and any other fixed-rate loan.
What is an amortization schedule?
An amortization schedule shows how each monthly payment is split between principal and interest over the life of the loan. Early payments go mostly toward interest, while later payments pay down more principal.
Is this loan calculator accurate?
Yes. It uses the same formula banks use. However, actual payments may vary slightly due to rounding, fees, taxes, or insurance not included here.
Is this loan calculator private? Does it store my financial info?
No. The payment schedule is computed in-browser from the principal, APR, and term you type. Your loan numbers are never posted to a server — the whole amortization walk runs inside this tab.
