Best Credit Unions for Auto Loans
Updated Q4 2025 · 6 min read · Data source: NCUA 5300 Call Reports
Auto loans are where credit unions shine most clearly. According to NCUA 5300 Call Report data for Q4 2025, the average credit union new-auto loan rate is 5.84% - compared to 6.82% at banks. On a $30,000, 48-month loan, that 0.98-point difference saves approximately $650 in interest over the loan term. See our methodology for how these rates are sourced; here's how to find the best rate.
Why Credit Union Auto Rates Are Lower
Credit unions don't have shareholders demanding profit returns. Surplus income goes back to members in the form of lower loan rates and higher savings rates. Auto loans are also a core product for most credit unions, they're very competitive for this product specifically.
How to Find the Best Rate
1. Start with Where You're Already Eligible
Your employer, school, military branch, professional association, or community may qualify you for specific credit unions. These often offer the best member rates. Check your employer's benefits portal or HR department.
2. Compare Rate Tiers
Credit union auto loan rates are typically tiered by:
- Credit score: Excellent credit (720+) qualifies for the lowest advertised rates
- Vehicle age: New cars get lower rates than used; older vehicles (7+ years) may face higher rates
- Loan term: Shorter terms (36–48 months) get better rates than 72–84 month loans
- Membership standing: Some CUs offer better rates to established members
3. Look for Financially Healthy CUs
A credit union with a health score of 70+ on PlainCU is in a strong financial position, which means it has the capital to offer competitive loan rates sustainably. A financially stressed CU might tighten lending standards or raise rates.
4. Check for Pre-Approval Before the Dealership
Get pre-approved at a credit union before visiting the dealer. This gives you a rate benchmark and protects you from dealer financing markups (dealers typically add 1–2% to the bank rate as their fee). Walking into a dealership with a pre-approval is one of the most powerful negotiating tools you have.
