A mortgage payoff calculator helps you estimate how long it will take to repay your home loan based on your loan amount, interest rate, and any extra monthly payments.

By entering an additional monthly payment, the calculator shows how much sooner you can repay your loan and how much interest you can save.

You need your loan amount, annual interest rate, loan term (in years), and any extra amount you plan to pay monthly.

This version supports monthly extra payments. For lump sum inclusion, you can request a custom version.

It is primarily designed for mortgages but can also be used for any amortized loan with fixed monthly payments.
