What determines your financing rate on a new car

Your financing rate — the percentage you pay annually to borrow money for a car — is set by the lender based on how risky they think lending to you is. The main factors are your credit score, the size of your down payment, the length of the loan, and current market conditions. A lender looks at your credit history to predict whether you'll pay them back on time. If you have a strong history of on-time payments, you get a lower rate. If you have missed payments or high debt, you get a higher rate.

The type of lender also matters. Banks, credit unions, and car dealerships all set their own rates. Credit unions often offer lower rates to their members than banks do. Dealerships sometimes offer promotional rates — especially on new models — but these are usually only available to buyers with good credit. The loan term you choose (how many months you take to repay) also affects your rate: a 36-month loan typically has a lower rate than a 72-month loan, because the lender's money is at risk for a shorter time.

Key Takeaways

  • Your credit score is the single biggest factor in the rate you receive, with scores above 750 typically unlocking the lowest rates available.
  • A larger down payment lowers your rate because the lender is lending you less money relative to the car's value.
  • Credit unions usually offer lower rates than banks or dealerships, so checking your credit union first can save you hundreds of dollars.
  • Shorter loan terms (36 to 48 months) come with lower rates than longer terms (60 to 84 months), though your monthly payment will be higher.
  • You can shop for rates from multiple lenders before buying, and dealers must disclose the rate they're offering you in writing before you sign.

How your credit score shapes your rate

Lenders use your credit score as the primary signal of risk. Credit scores range from 300 to 850, and most lenders have thresholds where your rate changes. A score of 750 or above typically qualifies you for the best rates available at that moment. Scores between 700 and 749 usually get a slightly higher rate. Scores between 650 and 699 see a noticeable jump. Below 650, rates climb steeply, and below 600, some lenders won't finance you at all.

Your credit score reflects five things: payment history (35 percent of your score), amounts you owe relative to your credit limits (30 percent), length of credit history (15 percent), mix of credit types like cards and loans (10 percent), and recent credit inquiries (10 percent). If you've missed payments in the past year or two, your score will be lower. If you're carrying high balances on credit cards, that also lowers your score. Checking your own credit report before you shop for a car lets you know what rate range to expect and gives you time to dispute any errors.

The role of your down payment and loan term

A down payment is money you put toward the car's price upfront, reducing the amount you need to borrow. The larger your down payment, the lower your rate, because the lender is financing a smaller portion of the car's value. A 20 percent down payment typically gets you a better rate than a 10 percent down payment. This is because if you stop paying and the lender has to repossess and sell the car, they're more likely to recover their money if they only financed 80 percent of its value.

Loan term — how many months you have to repay — also directly affects your rate. A 36-month loan usually has the lowest rate, a 48-month loan a slightly higher rate, and a 60-month or longer loan an even higher rate. The tradeoff is that a shorter term means a higher monthly payment. A 72-month or 84-month loan spreads the cost across more months, lowering your payment but raising your rate and the total interest you pay over the life of the loan. Before you choose a term, calculate the total amount you'll pay in interest at different lengths to see the real cost difference.

Where to shop for rates before you visit a dealership

You don't have to accept the rate a dealership offers. You can shop for rates from banks, credit unions, and online lenders before you buy, and use those offers to negotiate with the dealer. Many credit unions let you check rates without a hard credit inquiry, which doesn't affect your score. Banks and online lenders usually require a hard inquiry, which temporarily lowers your score by a few points, but multiple inquiries for the same type of loan (car loans) within 14 to 45 days typically count as a single inquiry for scoring purposes.

Getting a pre-approval letter from a lender shows you the rate and maximum loan amount you may have access to for. You can then walk into a dealership knowing your options. Dealerships sometimes match or beat outside rates to earn your business, and they're required by law to disclose the rate they're offering in writing before you sign any paperwork. If the dealer's rate is higher than what you've been offered elsewhere, you can decline their financing and use your pre-approval instead.

How market conditions and vehicle type affect rates

Interest rates in the broader economy — set by the Federal Reserve and reflected in what banks charge each other — influence car loan rates. When the Fed raises its benchmark rate, car loan rates typically rise within weeks. When the Fed lowers rates, car loan rates usually fall. You can't control these market conditions, but you can time your purchase if you're flexible. Rates that are high one month may be lower the next, especially if the Fed signals a rate cut.

The type of vehicle also matters slightly. New cars typically get lower rates than used cars, because new cars are less likely to have mechanical problems that leave the lender with a car they can't sell if they repossess it. Luxury or sports cars sometimes get higher rates than sedans or SUVs, depending on the lender's risk assessment. Certified pre-owned vehicles — used cars inspected and warranted by the manufacturer — usually get rates closer to new cars than to regular used cars.

Understanding the difference between APR and interest rate

The interest rate is the percentage of the loan amount you pay annually in interest. The APR (annual percentage rate) includes the interest rate plus other costs of borrowing, like origination fees or dealer documentation fees. The APR is always equal to or higher than the interest rate. Lenders are required to disclose both numbers, and the APR is what you should use when comparing offers from different lenders, because it gives you the true cost of borrowing.

For example, two lenders might offer you a 5 percent interest rate, but one might charge a $500 origination fee and the other might charge nothing. The lender with the fee will have a slightly higher APR. When you're comparing offers, look at the APR, not just the interest rate. The difference might be small, but over a five-year loan it adds up.

What happens after you're approved and sign the paperwork

Once you've signed a financing agreement, the lender owns the car until you pay off the loan. Your monthly payment goes to the lender, not the dealership. The lender also typically requires you to carry comprehensive and collision insurance on the car, which is different from the liability insurance your state requires. If you stop making payments, the lender can repossess the car, and you'll still owe the difference between what they sell it for and what you owe.

Some loans allow you to pay off the balance early without a penalty. Others charge a prepayment penalty — a fee for paying off the loan ahead of schedule. Before you sign, ask whether your loan has a prepayment penalty. If you come into money and want to pay off the car early, a penalty could cost you hundreds of dollars. Also ask about the loan's terms if you want to refinance later: some lenders make it straightforward, and others make it difficult or expensive.

Frequently Asked Questions

What credit score do I need to get a car loan?

Most lenders will finance someone with a score of 600 or above, though the rate will be high. Scores of 650 and up get better rates. Credit unions sometimes work with lower scores than banks do. If your score is below 600, you might need a co-signer or a larger down payment to be approved.

Can I negotiate my interest rate at the dealership?

You can negotiate the price of the car, but the interest rate is set by the lender, not the dealership. What you can do is shop for rates from other lenders first and tell the dealer what you've been offered. Some dealers will match or beat an outside rate to earn your business. Always get the dealer's rate offer in writing before you agree to anything.

Should I choose a shorter or longer loan term?

A shorter term (36 to 48 months) means a lower interest rate and less total interest paid, but a higher monthly payment. A longer term (60 to 84 months) means a lower monthly payment but a higher rate and much more interest paid overall. Calculate the total cost at each term length to see which fits your budget without costing you thousands in extra interest.

What's the difference between financing through a dealer and financing through my bank?

Banks and credit unions typically offer lower rates than dealerships, especially if you have good credit. Dealership financing is convenient because you handle everything in one place, but you'll usually pay more. Getting pre-approved at your bank or credit union before you shop gives you a baseline rate to compare against any dealer offer.

Can I refinance my car loan later if rates drop?

Yes. If interest rates fall after you buy, you can refinance your loan with a different lender at the new, lower rate. This makes sense if the new rate is at least 1 to 2 percentage points lower than your current rate and you have enough time left on your loan to recoup the refinancing costs. Check whether your current loan has a prepayment penalty before you refinance.
