What is an early payoff calculator?

An early payoff calculator shows how making extra payments on a loan reduces the total interest you pay and how many months or years sooner you become debt-free.

Do extra payments really save money?

Yes. Because interest is charged on the remaining balance, every extra dollar of principal you pay early removes all the future interest that dollar would have accrued over the life of the loan.

Does this work for mortgages, auto, and student loans?

Yes. Any fixed-rate, fully amortizing loan — mortgage, auto, personal, or student loan — follows the same math, so the calculator works for all of them.

Why paying a little extra changes everything

Interest compounds against you

Extra principal today erases every future interest charge that dollar would have created. Small amounts snowball.
