Auto loan Calculator

Estimate a monthly payment, projected payoff timeline, and total interest for an unsecured auto loan. Add an origination fee to see the effective APR, the true yearly cost after fees. Optionally model extra principal payments to see how they shorten the loan and reduce total interest paid.

Results are estimates based on your inputs. Actual terms depend on credit profile, lender policies, and state regulations. Sales tax treatment varies by state — some states tax only the financed portion after trade-in; confirm with your dealer.
