About this tool

A mortgage payment stays the same each month, but what’s inside it shifts dramatically: early payments are mostly interest, and only later does the principal fall quickly. This calculator shows your monthly payment and the full amortization schedule so you can see exactly where your money goes.

It also totals the interest over the life of the loan — often an eye-opening figure that shows the value of overpaying or a shorter term. Everything is computed in your browser.

Frequently asked questions

What is amortization?

It's how a loan is paid off over time. Early payments are mostly interest; later ones are mostly principal, while the monthly amount stays the same.

Does it show every month?

Yes. The first year is shown by default, and you can expand the full month-by-month schedule for the whole term.
