Mortgage Extra Payment and Payoff Calculator

EXTRA PAYMENT / PAYOFF

Pay it off early.iEvery dollar you add on top of your regular payment goes straight to principal — so you owe less, less interest accrues, and the loan ends sooner. Even a modest amount each month can cut years and tens of thousands in interest off a 30-year loan. Confirm your loan has no prepayment penalty (most don’t).

See how much faster you’d pay off your mortgage — and how much interest you’d save — by adding a little extra to principal each month.
