How this calculator works

Each month, interest is charged on the remaining balance at one-twelfth of the annual rate; the rest of your fixed payment reduces the principal. Any extra payment you add goes straight to principal, so the balance falls faster and less total interest accrues. We compare your schedule against the no-extra baseline to show the interest and time you save.

Frequently asked questions

What is an amortization schedule?

It's the month-by-month plan that shows how each payment splits between interest and principal, and how your balance falls to zero over the loan term. Early on, most of the payment is interest; over time, more goes to principal.

How much do extra payments save?

Extra principal payments reduce the balance faster, so less interest accrues and the loan ends sooner. Even a modest extra amount each month can save tens of thousands in interest and cut years off a 30-year loan. Enter an extra amount to see your exact savings.

Why is so much of my early payment interest?

Interest is charged on the outstanding balance, which is highest at the start. Because the payment is fixed, the interest portion is large early and the principal portion is small; the mix flips as the balance shrinks.
