Extra payments on auto loans: when it pays off
Extra payments on auto loans save less than mortgage extras because the loans are shorter (3-7 years) and rates lower. Early extra payments still save more than late ones because the principal is larger. Check for prepayment penalties first. On high-rate auto loans (7%+), extra payments outperform most safe investments after tax.

Extra payments on auto loans work the same way as mortgages — they reduce principal faster, which means less interest accrues.
The key difference: Auto loans are shorter (3–7 years) and typically lower-rate (3–8%) than mortgages. The savings from extra payments are real but smaller in absolute dollars.
Best time to make extra payments: Early in the loan. Interest in auto loans is mostly front-loaded — year 1 has the highest interest charges.
Check first: Some auto loans have prepayment penalties. Read your loan agreement before making extra payments.
