What Are Auto Loan Rates?
Auto loan rates are the annual percentage rate (APR) charged by lenders for vehicle financing. Unlike mortgage rates, auto loan rates vary significantly based on vehicle condition (new vs used vs certified pre-owned), vehicle age (model year eligibility), loan term (typically 36-72 months), vehicle type (car, truck, SUV, RV, motorcycle), and down payment or loan-to-value ratio.
Rate ranges as of January 28, 2026:
- New vehicles (60 months): 5.49% - 7.99% APR
- Used vehicles (60 months): 6.49% - 9.99% APR
- Electric vehicles (60 months): 4.99% - 7.49% APR
- Certified pre-owned (48 months): 5.99% - 8.49% APR

Lower Rates
Why Credit Unions for Auto Loans?
Credit unions consistently offer lower auto loan rates than banks and dealerships. Because they're member-owned, not-for-profit institutions, credit unions return profits to members through lower rates rather than paying shareholders or dealer networks.
1-2% Lower Than Banks
Credit unions offer 1-2% lower APR on average vs traditional banks. On a $30,000 vehicle, this saves $1,500-$2,000 over a 60-month loan.
2-4% Lower Than Dealers
Dealer financing includes markup (1-3% added to the buy rate). Credit unions eliminate this markup entirely, saving $2,000-$3,000 on typical loans.
Navy Federal Credit Union: 5.49% APR for new 60-month auto loans
Typical dealership financing: 7.99% APR for same vehicle
Savings: $2,850 over loan term on $30,000 vehicle
