The rate and terms on a car loan depend on how you apply as much as on your credit. These are the application mistakes that lead to higher rates, bigger loans and costlier terms, and what to do instead.
Quick summary
- Auto lenders consider your credit score and history, income, loan amount, down payment and loan term, and they are not required to offer you the best rate you qualify for.
- Check your credit reports before you shop and dispute any errors. Free reports are available at AnnualCreditReport.com or by calling 1-877-322-8228.
- Dealer-arranged financing starts at a buy rate the dealer can mark up, so a preapproved loan from a bank or credit union gives you a benchmark to negotiate against.
- Low monthly payments often mean longer terms and higher rates, which raise the total cost of the loan.
- Keep loan applications within a 14 to 45 day window so that multiple lender credit checks generally count as one inquiry.
Financing a car is one of the larger borrowing decisions most households make, and the terms you are offered depend heavily on how you apply, not just on your credit. Lenders consider your score, income, loan amount, down payment and the length of the loan, and neither dealers nor lenders are required to give you their best available rate. That makes the application process a place where avoidable mistakes get expensive. Here are the most common ones, what each one costs, and what to do instead.
What Lenders Look at Before Approving an Auto Loan
Auto lenders generally weigh several factors when deciding what interest rate and terms to offer: your credit score and history, your income, the amount of the loan, your down payment and the loan terms themselves. A credit score is a number, usually somewhere in the 300 to 850 range, that predicts how reliably a borrower will pay back what they owe and stay on schedule. The FICO model is the one most lenders rely on, though auto lenders can also use a FICO Auto Score, a version designed for vehicle financing that runs from 250 to 900. Scores from different models can differ, which our guide to FICO vs. VantageScore explains in more detail.
There is no minimum credit score required to get an auto loan. Each lender sets its own requirements, and some base their minimums on how much you are borrowing and the size of your down payment. A VantageScore of 661 or above is generally considered prime, and a FICO Score of 670 or higher is considered good; our guide to what counts as a good credit score covers the ranges. Lenders also look at how much of your income is already committed to debt payments, a measure explained in our guide to debt-to-income ratio.
Mistake 1: Shopping for the Car Before Checking Your Own Credit
The Federal Trade Commission recommends pulling your credit report ahead of any dealership visit, since what it contains shapes both your odds of approval and the rate you are offered to borrow. Free reports from the three nationwide credit bureaus, Equifax, Experian and TransUnion, are available at AnnualCreditReport.com or by calling 1-877-322-8228.
Skipping this step means an unnoticed error, such as a payment reported late by mistake, can follow you into a loan application and raise your rate. If you find mistakes, dispute them with the credit bureaus and with the business that supplied the information.
There is also a timing trade-off. If your score is on the low end, putting off the purchase for a few months can give you time to bring accounts current and pay down balances, which may qualify you for better terms. Experian’s State of the Automotive Finance Market report for the second quarter of 2026 put the average VantageScore for new car loan applicants at 751, and for used car loans at 688. Waiting is not always possible, but knowing where you stand before you settle on a car lets you decide deliberately.
If your credit history is thin, a lender may ask for a co-signer. A co-signer takes on equal responsibility for the contract: if you cannot pay what you owe, the co-signer is on the hook, and late payments hurt your credit and the co-signer’s. Treat that as a decision to make with eyes open, not a formality.
Mistake 2: Accepting the Dealer’s First Financing Offer
When you finance through a dealer, the dealer’s finance and insurance office sends your information to lenders, which quote the dealer a rate known as the buy rate. The rate the dealer offers you, called the contract rate, can be higher, because the dealer can profit by marking the rate up. Most dealers contact roughly five lenders and present you with one loan. You can ask whether there were other offers and whether any of them had lower rates or better terms.
The rate is negotiable, just like the price of the vehicle. Neither dealers nor lenders are required to offer you the best rate you qualify for, and the Consumer Financial Protection Bureau notes that comparing offers from other lenders and negotiating can save hundreds or even thousands of dollars over the life of the loan.
Where you borrow matters, especially for borrowers with lower scores. In a CFPB study of subprime auto loans, meaning loans to people whose scores are significantly lower than average, average rates were about 10 percent at banks compared with 15 to 20 percent at finance companies and buy-here-pay-here dealerships, which finance the loans themselves. The CFPB estimated that a borrower in its data with a 560-plus score would pay an estimated 13 percent at a small buy-here-pay-here lender versus 9 percent at a bank, saving around $900 over the life of the loan at the lower rate.
| Lender type | Average rate on subprime auto loans in the CFPB sample |
|---|---|
| Banks | About 10 percent |
| Finance companies | 15 to 20 percent |
| Buy-here-pay-here dealerships | 15 to 20 percent |
What to do instead: get preapproved by a bank or credit union before you shop. Preapproval gives you a loan quote with an interest rate, loan length and maximum amount, which becomes a benchmark to hold against whatever the dealer offers. You do not have to use the institution where you already bank.
Mistake 3: Focusing on the Monthly Payment Instead of the Total Cost
A low monthly payment is the easiest number to sell and one of the worst numbers to shop by. Lower monthly payments often come from longer loan terms and higher interest rates, which substantially increase what you pay overall. Two loans with the same payment can differ by thousands of dollars in total cost.
The fix is to negotiate the price of the car separately from the financing. Ask the dealer to send an out-the-door price, in writing, before any talk of financing starts: the total price of the car, including taxes and fees, before any loan is added. A written out-the-door price lets you compare dealers on equal terms, catch extra charges that slip into deals, and keep the conversation on total cost. When you judge affordability, use a budget worksheet to confirm your income covers your regular expenses plus the car payment, not just that a quoted payment seems manageable.
Mistake 4: Stretching the Loan Term to Lower the Payment
Lengthening the loan is the most common way to shrink a payment, and it works in the sense that the payment drops. The trade-off is that you pay interest for more months, and if the longer term also carries a higher rate, the total cost rises substantially. A longer term also raises the odds of owing more on the car than it is worth, a situation called negative equity. If you trade in that car before the loan is paid off, the negative equity can be rolled into your next loan, increasing the amount you borrow.
A down payment is the alternative worth comparing. Paying more upfront reduces the amount you finance, which lowers your total financing cost, and lenders consider the down payment when setting terms. Before choosing a length, ask for the total cost of the loan at two or three different terms and compare them side by side.
Mistake 5: Adding Extras and Gap Coverage Without Comparing Prices
The finance office is where add-ons get presented, and they are easy to accept because they are often quoted as a small change to the monthly payment. The FTC specifically warns that extra charges and add-ons can slip into your deal, which is another reason to insist on a written out-the-door price and read the contract carefully before signing.
Treat every add-on, including gap coverage, as a separate purchase. Ask what each one costs in full, how it changes the amount you are borrowing if it is rolled into the loan, and whether it is required for approval. Prices for products like gap coverage vary, so compare what your own insurer or other providers charge before agreeing at the dealership. If an add-on is optional and you do not want it, ask that it be removed from the contract.
Mistake 6: Spreading Loan Applications Across Too Many Weeks
Every time you apply for credit, the application shows up as an inquiry on your credit report, and applying for too many new accounts in a short period can hurt your score. The mistake runs in both directions. Some shoppers avoid applying anywhere out of fear and then accept a single offer without comparison. Others apply casually over the course of a month or more, stacking inquiries with no benefit.
Rate shopping itself is not the problem. Getting quotes from multiple auto lenders generally will not affect your score, as long as you keep your applications clustered. If several lenders check your credit, keeping your shopping within 14 to 45 days means those checks generally count as only one inquiry for scoring purposes. Our guide to hard vs. soft credit inquiries explains which checks affect your score and which do not.
Quick tip: Pick a one- to two-week window before you plan to buy, collect quotes from a few banks or credit unions during that window, and then negotiate with the dealer against your best quote.
What to Do the Week Before You Apply
- Pull your credit reports from all three bureaus at AnnualCreditReport.com and dispute anything that looks wrong.
- Review your budget to confirm what payment fits alongside your other expenses.
- Decide on a down payment amount. More down means less financed and a lower total cost.
- Research your trade-in’s value using the NADA Guides, Edmunds or Kelley Blue Book, and find out what you still owe on it. If your loan balance is higher than the car’s value, ask how that negative equity would affect the new loan.
- Get preapproved by at least one bank or credit union so you have a rate to compare against.
- Ask the dealer to send a written out-the-door price before any conversation about financing.
- Negotiate the car’s price first, and hold trade-in discussions until after, so a generous trade-in offer cannot offset a higher sales price.

Reader questions
Q: Is there a minimum credit score to buy a car?
A: No. Each lender sets its own requirements, and some base their minimums on the loan amount and down payment rather than the score alone. Borrowers in the prime range, 661 or above on a VantageScore, generally see the best terms.
Q: Can I negotiate the interest rate the dealer offers?
A: Yes. The rate is negotiable just like the price of the car. Ask whether other lender offers had lower rates, and compare the dealer’s offer against a preapproval from a bank or credit union.
Q: Will comparing loan offers hurt my credit score?
A: Getting quotes from multiple auto lenders generally will not affect your score if you keep your shopping within 14 to 45 days, because those credit checks generally count as only one inquiry.
Q: Should I ever choose a longer loan term?
A: Longer terms lower the monthly payment but raise the total cost, especially if the longer term carries a higher rate, and they increase the risk of owing more than the car is worth. Compare the total cost at several term lengths before deciding.
