What Factors Affect GMC Interest Rates?

When you’re financing, your GMC interest rate determines how much you’ll actually pay for your truck or SUV over time. Understanding what lenders look at to determine this rate can help you get a better deal. Here’s some advice on what matters from our team at Lester Glenn GMC in Toms River, NJ.

Your Credit Score

Auto lenders consider several factors including your credit score, your credit history, income, debts, and down payment when deciding what interest rate to offer you. According to Experian, the average auto loan rate for borrowers with super prime credit was 4.88 percent in the third quarter of 2025, versus an average 15.85 percent for borrowers with deep subprime credit. That gap can cost you thousands over the loan term.

Down Payment Size

Making a larger down payment can lower your monthly payment and potentially qualify you for a lower rate. More money down means you’re borrowing less, which reduces the lender’s risk and often results in better terms.

Loan Term Length

Shorter loan terms typically come with lower interest rates than longer ones. A 36-month loan will usually have a better rate than a 72-month loan, though your monthly payments will be higher.

New vs. Used

Choosing to buy a new vehicle as opposed to a used one also plays a huge role. New vehicles get better rates because they hold their value better and are less likely to need major repairs.
