Interest rates on auto loans are constantly changing, but the interest rate for a 60-month new car loan by Wells Fargo in June 2015 was about 3.1 percent for applicants with excellent credit history, according to WellsFargo.com. Many factors play a role in the interest rate.
The applicant's credit history and whether the vehicle is new or used are factors that determine what kind of interest rate is offered. A 60-month used car purchase has an interest rate of approximately 3.57 percent from Wells Fargo. Car loans almost always have lower rates for new cars versus used, and the better your credit score, the better the interest rate.
