How the estimate is built

Month-by-month simulation with and without extras; interest saved is the difference in total interest paid.

Example scenario

On an $18,400 balance at 6.9% with a $355 payment, an extra $75/month can save hundreds in interest and trim many months off the note.

FAQ

Will my lender apply extras to principal?

Most auto servicers do when you designate principal — confirm how you submit payment.

Payoff penalties?

Auto loans rarely penalize payoff; check your contract.

Biweekly payments?

Not modeled — use a biweekly mortgage tool for that schedule pattern on other debt.
