Auto Refinance Rates by Credit Score (2026 Breakdown)

June 20, 2026 · 6 min read · By Greg Parker

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.
