Auto Refinance Rates by Credit Score (2026 Breakdown)
Your credit score is the single biggest factor in the auto refinance rate you'll be offered. Here's what to realistically expect at each tier — and what you can do to get a better deal.
Average Auto Refinance Rates by Credit Tier (2026)
These ranges reflect typical offers from major auto refinance lenders:
- 720+ (Excellent): 4.5%–6.5% APR — You'll qualify for the best rates available. Lenders compete for your business.
- 650–719 (Good): 6.5%–9.5% APR — Solid offers, especially if you have stable income and low LTV.
- 580–649 (Fair): 9.5%–14% APR — Still significantly better than many original subprime loans (which can be 15%–25%).
- Below 580: 14%+ APR — Options exist but are limited. Consider improving your score first or adding a co-signer.
Why Even a Small Score Improvement Matters
Moving from 640 to 660 might seem minor, but it can cross a lender's tier threshold and drop your APR by 2–3 percentage points. On a $15,000 balance over 48 months, that's ~$1,000+ in savings.
How to Improve Your Rate (Any Score)
- Make 6+ months of on-time payments on your current loan before refinancing
- Pay down credit card balances to lower your utilization ratio
- Check your credit report for errors — disputes are free and can boost your score quickly
- Add a co-signer with stronger credit
- Choose a shorter term — lenders offer lower rates on 36-month vs. 72-month loans
- Shop within a 14-day window — multiple inquiries count as one
What If My Score Has Improved Since My Original Loan?
This is the most common — and most rewarding — reason to refinance. If you took your auto loan with a 580 score and you're now at 650, you could cut your APR nearly in half. Read our full bad-credit refinance guide for more.
