Frequently asked questions

What's included in the monthly payment?

Principal and interest plus monthly property tax, home insurance, and any HOA dues you enter. Lenders call the combined figure PITI.

How do extra payments save money?

Every extra dollar goes straight to principal, so future interest is charged on a smaller balance. That compounds, cutting both total interest and the number of payments.

Why is so much of my early payment interest?

Interest is charged on the outstanding balance, which is largest at the start. The amortization chart shows the principal share growing every year.

Is my data sent anywhere?

No. All calculations run in your browser. Nothing you type leaves your device.
