Question
Does the extra monthly payment go to principal?
Yes. This calculator assumes the extra monthly amount is applied directly to principal so the balance declines faster and future interest charges shrink.

Use your remaining mortgage balance, rate, term, and extra monthly principal payment to estimate payoff time and interest savings.
Why this result matters
A homeowner payoff-acceleration tool for estimating time saved and interest saved from extra monthly mortgage payments. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.
This mortgage payoff calculator helps homeowners test the payoff impact of sending extra money toward principal each month. By combining the remaining balance, annual rate, years left, and extra monthly payment, it estimates a faster payoff date, the months or years saved, and the interest avoided. That makes it a useful companion to standard mortgage payment and amortization tools.
Formula and method
The calculator uses standard mortgage amortization for the remaining balance and term, then simulates the loan month by month with optional extra monthly principal payments to estimate faster payoff and interest savings.
Example
If a homeowner has 320,000 left on the mortgage at 6.5% with 30 years remaining and adds 250 each month, the calculator estimates how much sooner the loan could be paid off and how much interest could be avoided.
