How to Get the Best Car Loan Rate
Check your credit score 3 months before buying and pay down credit card balances to improve it. Get pre-approved from at least two banks and your credit union. Use the pre-approval as leverage at the dealership. Never discuss monthly payment at the dealership — always negotiate the total purchase price first. Avoid 72-84 month loans which lead to negative equity.

What is a good interest rate for a car loan?
In 2026 a rate below 6% is excellent, 6-8% is good, 8-12% is average and above 12% is high. Rates depend on your credit score, loan term, vehicle age and lender.
Should I finance through the dealer or my bank?
Always get pre-approved by your bank or credit union before visiting the dealership. Use this as your negotiating baseline. Dealer financing can sometimes beat bank rates but often does not for buyers with good credit.
How much should my car payment be?
Your total transportation costs including car payment, insurance, gas and maintenance should not exceed 15-20% of your monthly take-home pay. Most financial advisors recommend keeping the car payment alone under 10-15%.
Is it better to make a larger down payment on a car?
Yes. A larger down payment reduces your loan amount, monthly payment and total interest paid. It also prevents being underwater on the loan. Aim for at least 20% down on a new car and 10% on used.
What is the difference between new and used car loan rates?
New car loan rates are typically 0.5-2% lower than used car rates because new cars have no history of problems. However used cars depreciate less so the total cost of ownership is usually lower for used vehicles.
