About this calculator
See how making extra monthly or one-time payments on your auto loan shortens your payoff timeline and reduces total interest paid.
Frequently Asked Questions
Does paying extra always reduce interest?
Yes, as long as the extra amount goes directly to principal, it reduces the balance interest accrues on, shortening the loan and cutting total interest paid.
Should I check for prepayment penalties?
Some auto loans include prepayment penalties. Check your loan agreement before making large extra payments.
Is a lump-sum extra payment better than monthly extra payments?
A lump sum applied early has a similar effect to spreading extra payments over time, but paying consistently each month is often easier to budget for.
