How your used car loan payment is calculated

A used car loan works like a new car loan—fixed monthly installments of interest and principal. Lenders often charge 1–3% more for used vehicles due to higher depreciation risk. Compare with our car loan calculator, auto loan calculator, trade-in calculator, affordability calculator, or main loan calculator.

Frequently asked questions

Why do used car loans cost more?
Lenders charge higher rates because used vehicles depreciate faster and carry more risk. Expect 1–3% more than new car rates.
Is this estimate accurate?
This shows principal and interest. Your lender may round differently or charge fees. Use it for planning; confirm with your lender.
Can I compare different terms?
Yes—change the term in months to see how 48 vs 60 vs 72 months affects your payment and total interest.
Should I get pre-approved before shopping used?
Yes. A bank or credit union pre-approval lets you compare dealer financing and often gets you a better rate on a used car.
Does this include taxes and registration?
No. Enter only the amount you finance. If taxes are rolled in, add them to the loan amount for a truer estimate.
