Mortgage Payoff Calculator — Description

The Mortgage Payoff Calculator estimates how long it will take to pay off your mortgage and how much interest you can save by making extra payments. Enter your remaining loan balance, annual interest rate (APR), and your monthly payment. Then add an optional extra payment (monthly or yearly) to see your new payoff timeline, total interest paid, and the difference compared to making only the base payment.

This calculator is ideal for homeowners who want to pay off debt faster, compare payoff strategies, or understand the impact of making consistent extra payments over time.
