Frequently asked questions

How is monthly mortgage payment calculated?

Payment = P × [r(1+r)^n] / [(1+r)^n − 1], where P is principal, r is monthly rate, and n is number of months.

Does this include taxes and insurance?

No. This calculator shows principal and interest only. Add property tax and insurance separately for total housing cost.

Can I see the full amortization schedule?

The table shows the first 12 months. Total interest and payment reflect the full loan term.

Is my data sent to a server?

No. All calculations happen in your browser.
