The best place for an auto loan depends on your credit score and whether you want to shop before or after picking a car

Banks, credit unions, and online lenders each have different approval speeds, interest rates, and requirements. Banks typically offer the lowest rates if your credit is good, but credit unions often approve people with fair or poor credit and charge less than dealerships. Online lenders approve quickly but may charge higher rates. The fastest route is to get pre-approved before you visit a dealership — this shows sellers you have real buying power and lets you compare what the dealer offers against what you already have.

Where you should go first depends on your credit score. If it's above 700, start with your own bank or a credit union where you already have an account — they know your history and move fast. If it's between 600 and 700, a credit union is usually your best option because they weight factors beyond the credit score. If it's below 600, an online lender or buy-here-pay-here dealership may be your only path, though the rates will be higher.

Key Takeaways

  • Credit unions typically offer lower rates than banks and dealerships, and they approve borrowers with fair credit more often than banks do.
  • Getting pre-approved at a bank or credit union before you shop gives you a real interest rate to compare against what the dealership offers.
  • Online lenders approve in one to three days but often charge 2 to 5 percentage points more than banks, so compare the total cost, not just the speed.
  • Dealership financing is convenient but almost always costs more — use it only if you cannot get approved elsewhere or if the dealer offers a promotional rate.
  • Your credit score, down payment size, and loan term all affect which lender will approve you and at what rate.

Banks and what they require

Traditional banks offer the lowest interest rates if your credit score is 700 or above. Wells Fargo, Chase, Bank of America, and regional banks all have auto loan programs. You can explore online or in person, and most will give you a decision within one to three business days. Banks typically require a credit check, proof of income (usually a recent pay stub and tax return), and proof of insurance before they fund the loan.

The catch is that banks are strict about credit. If your score is below 680, most banks will decline you or offer a rate so high that another lender is cheaper. Banks also require you to have a job and a stable address, and they verify both. If you are self-employed, bring two years of tax returns and a profit-and-loss statement. If you have changed jobs in the last six months, the bank may ask for a letter from your new employer confirming your hire date and salary.

One advantage of bank loans is that you can often get pre-approved without naming a specific car. This pre-approval is good for 30 to 60 days and shows dealerships that you have real financing lined up. It also lets you negotiate the car price separately from the financing — the dealer cannot use a low rate to hide a high purchase price.

Credit unions and their approval process

Credit unions usually offer rates 0.5 to 1 percentage point lower than banks, and they approve borrowers with credit scores between 600 and 700 more often. Navy Federal, Connexus, PenFed, and most local credit unions have auto loan programs. You must be a member to borrow, but membership is often free or costs $5 to $25 one time. Some credit unions let you join if you live or work in their service area; others require a family connection or membership in a specific group.

Credit unions move slower than banks — expect five to seven business days from process to funding — but they are more flexible about credit history. They look at your overall banking relationship with them, not just your credit score. If you have had a checking account there for two years with no overdrafts, a low score may not disqualify you. They also tend to approve self-employed borrowers more readily than banks do, though you will still need tax returns.

Many credit unions let you explore online and get a conditional approval the same day, then submit documents by mail or in person. If you already bank at a credit union, start there — they have your account history and can often move faster than a bank you have never used.

Online lenders and their speed versus cost

Online lenders like LendingClub, Upstart, and Lightstream approve in one to three days and fund within five to seven business days. They are fastest if you need money quickly and cannot wait for a bank or credit union. They also approve people with credit scores as low as 580 in some cases. You explore entirely online, upload documents as PDFs, and get a decision by email.

The trade-off is cost. Online lenders charge 2 to 5 percentage points more in interest than banks with the same credit score. On a $25,000 loan at 8% from a bank versus 12% from an online lender, you pay roughly $2,500 more over five years. Before you choose an online lender, calculate the total interest you will pay and compare it to what a credit union quoted. Sometimes the extra cost of waiting a week is worth the savings.

Online lenders also have stricter income requirements than credit unions. Most require a minimum annual income of $25,000 to $30,000 and proof of employment. Some will not lend to gig workers or people who have changed jobs in the last 90 days. Read the requirements carefully before you explore, because each process triggers a hard credit inquiry that temporarily lowers your score.

Dealership financing and when to use it

Dealership financing is the most expensive option in most cases. Dealers work with multiple lenders and mark up the interest rate by 1 to 3 percentage points before offering it to you. If a lender approves you at 6%, the dealer may offer you 8% or 9% and keep the difference. Dealers also bundle in add-ons like extended warranties, gap insurance, and paint protection that you may not need.

The only reasons to use dealership financing are: you cannot get approved anywhere else, the dealer is offering a promotional rate (usually 0% for 36 to 60 months on new cars), or you are trading in a car and the dealer is giving you a large credit that makes the math work. If you have a pre-approval from a bank or credit union, tell the dealer your rate and ask them to beat it. Many will, because they make money on the sale either way.

If you do finance through the dealer, read every page of the contract. Dealers sometimes add items you did not agree to, and you have a short window (usually three to five days) to cancel the deal if you change your mind. Some states let you cancel within a certain period; others do not, so check your state's rules.

Buy-here-pay-here dealerships for poor credit

Buy-here-pay-here dealerships lend to people with credit scores below 550 and often do not check credit at all. They sell used cars and finance them in-house, meaning they are both the seller and the lender. You make weekly or bi-weekly payments in cash or at their office, not to a bank.

These dealerships charge very high interest rates — often 18% to 29% annually — and require a large down payment, usually $1,000 to $3,000. They also install GPS trackers on the car and can disable it remotely if you miss a payment. The cars are usually 10 to 15 years old and may have high mileage. Use this option only if you cannot get approved for a traditional loan and need a car when ready for work.

How to compare offers from different lenders

When you get quotes from multiple lenders, compare the annual percentage rate (APR), not just the interest rate. The APR includes the interest rate plus fees, so it is the true cost of borrowing. A loan with a 6% APR is always cheaper than one with a 7% APR, all else equal.

Also compare the total amount you will pay over the life of the loan. A $25,000 loan at 6% for 60 months costs $3,300 in interest; the same loan at 8% costs $4,400. That $1,100 difference is real money. Use an online calculator to see the total cost for each offer, then decide whether the faster approval or lower monthly payment is worth the extra interest.

Get all quotes within a two-week window. Multiple credit inquiries from different lenders within 14 days count as one inquiry on your credit report, so your score does not drop each time. After two weeks, each new inquiry lowers your score by a few points.

What documents you will need

Every lender requires proof of income, identity, and residence. Bring a recent pay stub (within 30 days), a government-issued ID, and a utility bill or lease in your name. If you are self-employed, bring two years of tax returns and a current profit-and-loss statement. If you are retired, bring a Social Security statement or pension letter showing your monthly income.

You will also need proof of insurance before the lender funds the loan. Call an insurance agent and get a quote for the car you are buying, then provide the lender with a declarations page showing the vehicle identification number (VIN), coverage limits, and your name as the insured. The lender will be listed as the lienholder, which is normal — it means they own the car until you pay off the loan.

If you are buying from a private seller, bring the title and bill of sale. If you are buying from a dealership, the dealer handles the title paperwork. Have the VIN ready before you explore, because lenders use it to verify the car exists and to check for liens or salvage history.

Frequently Asked Questions

Should I get pre-approved before I go to the dealership?

Yes. Pre-approval shows you have real financing and lets you negotiate the car price without the dealer using a low rate to hide a high price. It also gives you a rate to compare against what the dealer offers. Pre-approval is good for 30 to 60 days and does not commit you to anything.

What if my credit score is below 600?

Credit unions and online lenders will consider you, though rates will be higher. A buy-here-pay-here dealership will lend to you, but expect 18% to 29% interest and a large down payment. If possible, wait three to six months, pay down other debts, and dispute any errors on your credit report — your score may improve enough to get a better rate.

Can I refinance my auto loan later if rates drop?

Yes. If interest rates fall or your credit score improves, you can refinance with a different lender. You will pay a small fee to the new lender and the old loan is paid off. Refinancing makes sense if the new rate is at least 1 percentage point lower and you have at least two years left on the loan.

What is the difference between APR and interest rate?

The interest rate is what you pay to borrow the money. The APR includes the interest rate plus fees, so it is the true cost. Always compare APRs, not interest rates, because two lenders with the same interest rate may charge different fees.

Do I have to buy the car the lender approves me for?

No. Pre-approval gives you a maximum loan amount, but you can borrow less. If you are approved for $30,000 and find a car for $22,000, you borrow $22,000. You can also shop for a different car as long as you use the loan within the pre-approval window, usually 30 to 60 days.
