How much total interest do you pay on a car loan?

On a $30,000 loan at 7% APR: 48 months: $4,448 interest. 60 months: $5,605. 72 months: $6,791. 84 months: $8,015. Each extra 12 months of financing adds $1,200-1,500 in interest for a typical car purchase.

Does making extra payments on a car loan help?

Yes — extra principal payments reduce total interest and shorten loan life. An extra $100/month on a 60-month $25,000 loan at 6% saves $700 in interest and pays off 8 months early. Apply extra payments directly to principal for maximum effect.

Is a 0% APR car deal actually free?

0% APR deals from manufacturers require excellent credit (720+) and sacrifice the cash rebate (typically $1,500-4,000). Compare: 0% APR on $30,000 (give up $3,000 rebate) vs 5% APR on $27,000 loan ($3,564 interest). In this case, 0% APR is better by ~$400.
