Where to find your numbers
- Loan balance: your lender's app or statement — or ask for the payoff amount, which is what a new lender would pay off.
- Current interest rate: the Annual Percentage Rate box on your retail installment contract.
- Months left: your original term minus payments made.
What this estimate does — and doesn't — include
It compares your current payment with the payment at the comparison rate over the same months left, using standard amortization. It doesn't include fees a new lender may charge or any change in term. The rate you're offered depends on your credit, income, the car's value, and the lender.

Common questions
Does this calculator check my credit?
No. It runs in your browser on the numbers you type. Nothing is stored or sent.
Why does the comparison rate change when I pick a credit range?
It starts at a typical rate for that range so you have a reasonable starting point. Replace it with a real offer if you have one.
