What to compare

Enter your payoff balance (not the original amount), current APR and months left, then the new APR, term and any fees (title transfer, lender fee). Keeping the same number of months isolates the rate savings; a longer term lowers the payment but usually raises total interest.

Cars lose value quickly, so lenders may decline a refinance if you owe more than the car is worth.

Example rates are for comparison only, not offers or current quotes. Your rate depends on credit, loan-to-value and lender.
