CALCULATOR GUIDE
About the Mortgage Payoff Calculator

How the calculation works
Extra principal reduces the balance on which future interest accrues; savings depend on when the servicer applies the payment.
Example
If the remaining balance is $240,000, compare the scheduled payment with an additional principal payment using your actual rate and remaining term.
Things to keep in mind
- Use the current remaining principal balance, not the original purchase price.
- Check prepayment rules and confirm that extra amounts are applied to principal.
- The result is an estimate based on the inputs and assumptions provided.
- Check applicable terms and official guidance before making financial, employment or academic decisions.
