Why extras work on installment loans.

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.
