The one amortization tool you can actually download

Most mortgage and loan calculators show you a schedule on screen and stop there — if you want it in a spreadsheet, you are sent to a blank template to re-type everything yourself. PayoffSchedule.com exports the exact schedule you just calculated: a formatted Excel workbook with a summary tab, a clean CSV for your own analysis, or a printable PDF to bring to your lender or keep for taxes.

What you can model

  • Extra payments — add a fixed amount to every payment and watch the payoff date move up.
  • One-time lump sum — apply a bonus or tax refund at any point in the loan.
  • Biweekly plan — pay half the monthly amount every two weeks (26 payments a year) to make one extra payment annually.
  • Any fixed-rate loan — mortgage, auto, personal or student, all in one calculator.
Every schedule includes the columns lenders' free tools usually skip — beginning balance, cumulative interest and cumulative principal — so you can track exactly how your equity grows and how much interest is deductible each year.

Frequently asked questions

Is this payoff schedule calculator free?
Yes. Every calculator and every download (Excel, CSV and PDF) is completely free, with no sign-up required.
Can I download my amortization schedule to Excel?
Yes — this is what makes PayoffSchedule different. One click exports your exact, just-calculated schedule to a formatted .xlsx workbook (with a summary tab), a clean .csv, or a printable PDF. You do not need to own a template or re-type your numbers.
Does adding extra payments really save money?
Yes. Extra principal payments shorten the loan term and cut total interest, because interest is charged on the remaining balance. The calculator shows exactly how much interest and time you save versus the standard plan.
Does the calculator work for car loans too?
Yes. Switch the loan type to Auto, Personal or Student. The same engine handles any fixed-rate amortizing loan, with sensible term presets for each.
Is my information saved or sent anywhere?
No. All calculations happen entirely in your browser. Nothing you type is uploaded to a server.
