- Shop lenders: Banks, credit unions, and online lenders all offer auto refinancing.
Frequently Asked Questions
QWhen is refinancing a car worth it?
Refinancing is usually worth it if you can get an interest rate at least 1-2% lower than your current rate, your credit has improved since you got the original loan, or you need to lower your monthly payment. Calculate the break-even point including any refinance fees.
QDoes refinancing a car hurt your credit?
Refinancing causes a small, temporary dip in your credit score (5-15 points) from the hard inquiry, but the impact is usually minimal and short-lived. If you make on-time payments on the new loan, it can actually help your credit over time by reducing your credit utilization ratio.
QCan I refinance a car with bad credit?
It is possible but harder to get favorable rates. If your credit has improved since the original loan, you may still qualify for a better rate. Lenders typically prefer borrowers with 600+ credit scores for refinancing, and the best rates go to 700+.
