Pay Off a $15,000 Car Loan at 8% APR

A $15,000 car loan at 8% APR costs noticeably more over the life of the loan than the same balance at a prime rate. The table below breaks down what $15,000 actually costs at 8% across a few common terms.

Car loans use simple monthly interest, not the daily compounding a credit card uses: each month, interest accrues once on the $15,000 remaining balance at 8%/12, then the payment is applied. That works out to roughly $100 in interest during the first month alone before the balance starts moving. That's a fundamentally different calculation than a revolving credit card balance on $15,000, where interest at 8% would compound daily on top of itself.
