How a loan payoff calculator works
Every loan on this site is modelled with the same monthly amortization math lenders use. Each month, interest accrues on the balance you still owe — your annual rate divided by twelve — and the rest of your payment reduces the principal. Repeat until the balance hits zero, and the month it does is your payoff date.
Because interest is charged on the remaining balance, retiring principal early removes every future interest charge that dollar would have generated. That is why a small, consistent extra payment can take years off a mortgage and thousands off a car loan. Each calculator shows the comparison directly: standard schedule versus your schedule with extra payments, in dollars and in months.
Nothing you type is sent anywhere — the math runs in your browser. Results are planning estimates that exclude escrow, taxes, insurance and fees; confirm exact payoff figures with your lender.
