About

This calculator compares a shorter term, a lower payment, extra principal payments, bi-weekly payments, and refinancing for a U.S. mortgage in dollars. The math runs entirely in your browser. The loan details you enter are not uploaded, and we do not collect them.

Disclaimer

Results are estimates, not a loan offer. Lenders differ on interest accrual, payment dates, rounding, PMI cancellation, and adjustable-rate caps. Your actual payment and interest are set by your note, mortgage statement, and closing disclosure.
