Overview

How refinancing can help

Refinancing replaces your current auto loan with a new one. The goal may be to lower your monthly payment, reduce your interest rate, shorten your payoff time, or adjust your loan to better fit your budget.

Lower your payment

A lower rate or longer term may reduce your monthly cost. This can create more room in your budget, but extending the term may increase total interest.


Compare total cost

A refinance calculator helps you look beyond the monthly payment. Compare how much interest you may pay over the rest of your loan under different scenarios.


Review your timing

Refinancing may make more sense if your credit has improved, rates have dropped, or you want to change the remaining term on your loan.


Check the trade-offs

A lower payment is not always the lowest-cost option. Use the numbers to weigh savings, payoff speed, and long-term affordability.

Calculator tips

What to enter before you compare

Start with your current loan balance, interest rate, and remaining months. Then enter the new rate and new term you want to test. If your lender charges fees, include those in your review so your estimate is more realistic.

It also helps to think about your goal before you refinance. If you want a lower payment, test a few longer terms. If you want to save on interest, compare shorter terms and lower rates side by side.
