Loan Calculator

Monthly payments and amortization.

Runs in your browser

About

Loan Calculator computes the fixed monthly payment for a loan from its principal, interest rate, and term, then shows a full amortization schedule — how much of each payment goes to principal versus interest over time — as both a chart and an optional detailed table. It's the same standard amortization formula lenders use, not an approximation. Nothing about your loan numbers leaves your browser.

Frequently asked

Does it show a full amortization schedule, or just the monthly payment?
Both — the monthly payment is the headline number, but a full payment-by-payment schedule and a principal-vs-interest chart are available too.
Is my loan information sent anywhere?
No, the calculation is a standard amortization formula computed entirely in your browser; nothing is transmitted or stored.
