This page is designed to help you find out whether MortMetrix is good and if it is the right choice for you.
MortMetrix is a free mortgage payoff tracker for homeowners who want to know what's actually happening with their loan. Most lender portals show you a balance and a due date. They don't tell you when you'll really be mortgage-free, how much of your home you own, or what an extra $100 a month would change.
That gap is why MortMetrix exists. Only about 1 in 4 homeowners ever pay extra toward principal, and most never run the numbers to see what it could save them. Years of extra interest end up being paid simply because the math was never visible.
To get started, you enter your balance, rate, and term once. You can begin from where you are today, even years into the loan, without digging up old payment history. MortMetrix builds a full amortization schedule on the same math your lender uses and keeps your balance current automatically as regular payments post.
From there you can see your payoff date, equity, and interest saved in one dashboard. You can test extra or lump-sum payments before committing a dollar. A PMI countdown shows when PMI is projected to drop off at 80% LTV, and an Original vs Actual view compares your progress to the schedule you started with.
There's no bank login and no spreadsheets. You just add your loan numbers, and in a few minutes you can see how much faster you could be mortgage-free.

Extra Payment Impact
See your new payoff date, months saved, and interest saved before you commit a dollar — even a small extra payment can cut years off your loan.

Payment Tracking
Regular payments track automatically against your schedule — just log the extra ones when you make them.
MortMetrix is a tracker, not just a calculator. It keeps your original amortization schedule as a baseline and tracks your loan against it over time, so you can see the interest you've already saved, not only what you might save. It starts from your current balance, so you don't need years of payment history, and it never asks for a bank login. Payoff date, equity, PMI countdown, and a what-if simulator for extra payments all live in one dashboard, built on the same amortization math your lender uses.
Most alternatives only do part of the job. Lender portals show your balance but rarely let you test extra payments. Online calculators give a one-time answer and forget you. Spreadsheets work until a missed month or an irregular payment breaks the formulas. Finance apps that track mortgages usually want you to link your bank account. MortMetrix does planning and tracking in one free tool: test an extra payment before you make it, then see its real effect on your payoff date, interest, and equity as the months go by, using only the loan numbers you enter.
MortMetrix started from a simple frustration. My lender's portal showed a balance and a due date, but not when the loan would actually be paid off or what an extra $100 or $200 a month would change. Online calculators answered once and then forgot me, and spreadsheets fell apart after a few months of irregular payments. I'm a software engineer, so I built the tool I wanted: enter your loan once, see your real payoff date, and watch extra payments move it over time. It launched in 2026 as a free web app, and the goal hasn't changed: make mortgage math visible so more homeowners pay less interest.
MortMetrix is built for individual homeowners, not businesses, so there are no corporate customers to name. It's free to use and launched in 2026, and its users are homeowners tracking their own mortgages and testing extra payments.
