A free, fast and transparent amortization calculator — no signup, no fees, no agenda. Just accurate math and clear answers.
Borrowing money is one of the biggest financial decisions most people make. Yet understanding exactly how a loan works — how much of each payment is eaten up by interest, when you'll build real equity, how much you'd save by paying a little extra each month — has always required either expensive software or a financial advisor.
We built amortization.us.com to change that. Our mission is simple: give every person in the United States instant, free and genuinely useful access to amortization calculations — with no registration, no fees, and no hidden agenda.
Results appear as you type. No waiting, no loading screens, no "submit" buttons to click through.
Your calculator inputs never leave your device. We do not store, log, or transmit any financial data you enter.
Full amortization schedules, visual charts, extra payment analysis, and CSV export — not just a single number.
Fully optimized for mobile, tablet, and desktop. Use it on your phone at the bank or on your laptop at home.
Our comprehensive guide explains amortization for every major loan type — in plain English, with real USD examples.
All examples, rates, and guidance are tailored to the United States market and denominated in US dollars.
The idea for amortization.us.com came from a frustration that many people share: you're sitting with a mortgage offer, a car loan, or a student loan repayment plan — and you want to understand the numbers. You search online, and you find either a cluttered calculator buried inside a site trying to sell you a loan or a bare-bones tool that spits out one number with no context.
We wanted something different. A calculator that shows you the full picture — not just your monthly payment, but your complete amortization schedule, a visual breakdown of principal versus interest and the ability to model what happens when you make extra payments. A tool that respects your time and your privacy.
So that's what we built. amortization.us.com is designed to be the most useful, most transparent and easiest-to-use amortization calculator available — completely free, forever.
amortization.us.com is a free service. To support the costs of running and maintaining the Site, we display advertisements through Google AdSense and may work with other advertising networks in the future. Advertisements are clearly identified and are served automatically — they do not influence our calculator's results, our editorial content or any guidance we provide. We never accept payment to recommend specific financial products or lenders. For more details, see our Privacy Policy and Terms and Conditions.
Our amortization calculator uses the standard fixed-rate amortization formula generally used by lenders throughout the United States. The math is the same math your bank uses to calculate your payment schedule.
That said, our calculator provides estimates. Your actual loan payments may differ due to fees, closing costs, escrow requirements (for mortgages), insurance, taxes, rounding conventions used by your specific lender or because your loan has variable-rate components. We always recommend confirming your figures with your lender or a licensed financial advisor.
We review and update our content and rate benchmarks regularly to keep our educational guide current with US market conditions. If you spot an error or have a suggestion, we'd love to hear from you at hello [at] amortization.us.com
