Mortgage Payoff Calculator

Compare your scheduled mortgage payoff with extra monthly or one-time principal payments.

This models principal-and-interest only. It does not include escrow, prepayment penalties, recast rules, ARM changes or lender-specific servicing rules.

How to read the payoff comparison

The calculator first estimates your scheduled principal-and-interest payment from the current balance, rate and remaining term. It then applies your extra monthly or one-time principal payments month by month so you can compare payoff date, interest saved and time saved.

Example

If your balance is $280,000 at 6.25% with 24 years remaining, adding $200 per month reduces principal faster than the scheduled payment alone. The exact time saved depends on the current payment, rate and how the servicer applies the extra amount.

Common mistakes

Tell the servicer that extra payments should go to principal when that option is available. If extra money is held as a future payment or applied to escrow, the interest savings may not match the estimate.

What this does not include

This is not a lender payoff quote. Ask your servicer how extra payments are applied, whether prepayment penalties exist and whether escrow, fees or a formal payoff statement affect the amount needed to close the loan.
