Designed to answer the homeowner's main question
What happens if I pay extra on my mortgage? Enter your current mortgage balance, interest rate, monthly payment, and optional extra payment. Mortgage Payoff Calculator immediately shows the effect on your payoff.
See the actual Windows software
The interface is designed around the questions homeowners usually ask: when will the mortgage be paid off, how much time can extra payments save, and how much interest can be avoided?
Payoff results at a glance
Enter the current balance, rate, monthly payment, and extra amount. The program shows the estimated payoff month, time saved, and interest saved.
Simple monthly schedule
Review each payment month and change the Extra amount for a single month when you expect to pay more or less.

Month-based by design
This product intentionally stays simple. It plans mortgage payoff by month, not by exact day. It does not attempt to reproduce a mortgage servicer's daily-interest payoff quote, escrow accounting, taxes, insurance, fees, or other servicer-specific rules.
For an exact payoff amount through a specific date, request a payoff statement from your mortgage servicer. For professional loan schedules with irregular dates, changing rates, and more advanced calculation methods, use Amortization Pro.
