About MortMetrix and Diffee

In their own words, as submitted to SaaSHub.

MortMetrix

Diffee

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...

Questions & Answers

As answered by people managing MortMetrix and Diffee.

What makes your product unique?

MortMetrix's answer

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.

Why should a person choose your product over its competitors?

MortMetrix's answer

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.

What's the story behind your product?

MortMetrix's answer

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.

Who are some of the biggest customers of your product?

MortMetrix's answer

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.
