When should you refinance a car loan?

Good times to refinance: your credit score has improved significantly since the original loan, interest rates have dropped, you got dealer financing at a high rate, or you're struggling with your current payment and want to extend the term. Avoid refinancing if you're close to paying off the loan — the savings rarely justify the costs.

Does refinancing a car loan hurt your credit?

Refinancing causes a hard inquiry which may temporarily lower your score by a few points. If you're shopping multiple lenders, do so within a 14-45 day window — credit bureaus typically treat multiple auto loan inquiries within this period as a single inquiry.

How much does it cost to refinance a car loan?

Most auto refinances have minimal fees: a title transfer fee ($25-$75 in most states) and potentially a loan origination fee (0.5-1% of the loan amount at some lenders). Many online lenders charge nothing. The key cost is if you extend your term — you may pay less per month but more total.

Can you refinance a car loan with bad credit?

Yes, but options are limited and rates may not improve. Credit unions are often more flexible than banks. If you've made on-time payments for 12+ months on your current loan, some lenders will approve a refinance. If your score improved from the original loan, even modestly, you may qualify for a better rate.

How to Get the Best Refinance Rate

Your credit score is the single biggest factor. Check your score before applying — if it's improved by 30+ points since your original loan, you almost certainly qualify for a lower rate. Credit unions typically offer the lowest auto loan rates, often 1-2% below banks and dealers.

The average new-car refinance rate in 2026 is around 5.5-7% for excellent credit (720+) and 7-12% for fair credit (580-680). If your original loan was dealer-arranged, you likely have significant room to refinance lower — dealers often mark up rates 2-3% for profit.

Should You Refinance Your Auto Loan in 2026?

Auto loan refinancing replaces your current car loan with a new one — typically at a lower interest rate or different term. The average auto loan rate in 2026 is approximately 7.1% for new cars and 11.3% for used cars (Experian). If your credit score has improved or market rates have fallen since you financed, refinancing can produce meaningful savings.

Break-Even Point Formula

Break-even months = refinancing costs ÷ monthly payment savings. If refinancing saves $80/month and costs $400 in fees, break-even is 5 months. Refinancing makes sense if you plan to keep the vehicle past the break-even point.

When to Refinance

Your credit score improved 50+ points since the original loan

You financed through a dealership at a high rate and can now qualify for a credit union rate

You want to lower monthly payments by extending the term (note: total interest increases)

Refinancing is less beneficial if your vehicle is more than 7 years old or has over 100,000 miles (many lenders won't refinance), you're near the end of your loan term, or your current rate is already below 5%.
