Car loans come from banks, credit unions, online lenders, and dealerships — each with different speed, rates, and document requirements
You can get a car loan from four main sources: your bank, a credit union, an online lender, or the dealership itself. Banks and credit unions usually offer the lowest rates if you have decent credit, but they take longer to approve. Online lenders move faster and may accept lower credit scores, but charge higher rates. Dealership financing is the quickest but often the most expensive. The lender you choose depends on how much time you have, what your credit looks like, and whether you want to shop for the car first or get pre-approved for a loan amount first.
Each lender type has a different approval timeline and set of expectations. Understanding what each one needs from you — and what you get in return — helps you pick the right fit for your situation and avoid surprises when you explore.
Key Takeaways
- Banks and credit unions typically offer the lowest interest rates, but require good credit and take one to three business days to approve.
- Online lenders can approve you in hours and accept lower credit scores, but charge higher rates than traditional banks.
- Dealership financing closes the fastest but usually costs more in interest, and you cannot shop rates before you pick a car.
- Getting pre-approved before you shop lets you negotiate with the dealer as a cash buyer and compare your own rate to what the dealer offers.
- Lenders will ask for proof of income, employment, residence, and insurance before they fund the loan.
Banks: Lowest rates, but you need good credit and time
Banks offer the lowest interest rates if you have a credit score of 700 or higher and a steady income. You can walk into a branch or explore online. The bank will ask for your driver's license, proof of income (usually a recent pay stub), proof of residence (a utility bill or lease), and proof of employment. They will also pull your credit report. The whole process takes one to three business days.
The catch: banks want to know what car you are buying before they approve the loan, so you need the vehicle identification number (VIN) and the sale price. If you have not found the car yet, you can ask for a pre-approval letter that states a loan amount without a specific vehicle attached — this lets you shop with confidence and negotiate with the dealer. Once you pick a car, you come back with the VIN and the bank finalizes the loan. Many banks will issue this pre-approval letter the same day you explore, so you can start shopping when ready while the paperwork processes in the background.
Credit unions: Competitive rates and sometimes more flexible credit requirements
Credit unions often match or beat bank rates and may approve you with a credit score as low as 650, depending on the union. You have to be a member to borrow, but membership is usually free or costs a small one-time fee. You can join online or in person at a branch. If you already belong to a credit union, calling them first is often the fastest way to find out what rate you would get.
The approval process is similar to a bank: you provide a driver's license, proof of income, proof of residence, and employment verification. Credit unions typically take one to three business days. Like banks, they will ask for the VIN and sale price, or they can issue a pre-approval letter for a loan amount so you can shop first. Some credit unions are more willing to work with you if you have other accounts with them, so mention any savings or checking accounts you hold when you explore.
Online lenders: Fast approval, higher rates, looser credit standards
Online lenders can approve you in a few hours and often accept credit scores as low as 580. They work entirely by phone, email, and upload — no branch visit needed. You explore on their website, upload your documents (driver's license, recent pay stub, proof of residence), and they give you a decision the same day or next morning. This speed makes online lenders attractive if you need to close quickly or if you are buying from a private seller who wants cash fast.
The tradeoff is interest rate. Online lenders charge more than banks or credit unions because they take on more risk with lower credit scores. They also require the VIN and sale price before they approve, so you cannot get a pre-approval letter for a loan amount. This means you either have to find the car first, or you get approved only after you have picked one out. Some online lenders work with dealerships directly, so the dealer can submit your process while you are on the lot — but the dealer is not obligated to tell you the rate until you sign.
Dealership financing: Fastest closing, but usually the most expensive
The dealership can arrange financing on the spot, and you can drive off the lot the same day. The dealer works with multiple lenders behind the scenes and presents you with one or two loan offers. The whole process takes a few hours. This convenience is valuable if you have found the exact car you want and do not want to wait for bank approval.
The downside is cost. Dealership rates are almost always higher than what you would get from a bank or credit union, because the dealer marks up the rate and keeps the difference. You also cannot shop rates — you see only what the dealer offers. If you have not been pre-approved elsewhere, you have no way to know if the dealer's offer is competitive. This is why getting pre-approved at a bank or credit union first is so valuable: you walk in knowing your rate, and you can tell the dealer "I have an offer at 6.5 percent" and ask them to beat it.
How to compare and decide which lender to use
Start by checking your credit score. If it is 700 or higher, call your bank and credit union first — they will give you a rate quote in minutes. If it is between 650 and 700, focus on credit unions. If it is below 650, online lenders are your main option. You can check your credit score for free through your bank's website, your credit card issuer, or a free service like Credit Karma or AnnualCreditReport.com.
Next, decide whether you want to shop for the car first or get pre-approved for a loan amount first. Pre-approval is usually smarter: you know your budget, you can negotiate with the dealer as a cash buyer, and you can compare the dealer's offer to your own rate. To get pre-approved, you need the loan amount you want (not a specific car), your income, and your employment information. Banks and credit unions can issue a pre-approval letter in one to three days. Online lenders typically cannot pre-approve without a VIN.
Once you have pre-approval offers from two or three lenders, compare the interest rate, the loan term (36, 48, 60 months, etc.), and any fees. Some lenders charge origination fees or prepayment penalties — ask about these before you commit. Then pick the lender with the lowest total cost, not just the lowest rate. A lower rate over a longer term might cost you more in total interest than a slightly higher rate over a shorter term.
What documents you need to have ready
Every lender will ask for the same core documents. Have these ready before you explore: a government-issued photo ID (driver's license or passport), a recent pay stub or tax return showing your income, a utility bill or lease showing your current address, and the name and phone number of your employer. If you are self-employed, bring two years of tax returns and a profit-and-loss statement. Having these documents scanned or photographed on your phone speeds up the online process process.
You will also need proof of auto insurance before the lender funds the loan. You do not have to have the policy yet, but you need a quote or a declaration page showing that you have coverage lined up. Some lenders let you provide this after approval but before closing. If you are buying a used car, some lenders also ask for a vehicle history report (like a Carfax) to confirm the car's condition and mileage. This report costs about $25 and is worth getting yourself if you are serious about a particular car, because it shows you the car's accident history before you commit to financing it.
What happens after you are approved
Once a lender approves you, they send you a loan document (called a promissory note or loan agreement) to sign. This spells out the interest rate, the monthly payment, the loan term, and any fees. Read it carefully — this is your chance to catch any mistakes or surprises. If something does not match what you were quoted, call the lender and ask them to correct it before you sign. Do not sign anything you do not understand, and do not let a dealer or lender rush you through the paperwork.
After you sign, the lender funds the money. If you are buying from a dealership, the dealer usually handles the paperwork and the lender sends the money directly to the dealer. If you are buying from a private seller or a used car lot, the lender sends you a check or wires the money to you, and you pay the seller. Either way, the lender will file a lien on the car's title — this means they own the car until you pay off the loan. You will get the title once the loan is paid in full. Keep your loan documents in a safe place; you will need them if you ever want to refinance or sell the car before the loan is paid off.
Frequently Asked Questions
Can I get a car loan with bad credit?
Yes. Online lenders will work with credit scores as low as 580, though your interest rate will be significantly higher than someone with good credit. Credit unions sometimes accept scores in the 650 range. If your score is very low, getting pre-approved at an online lender before you shop gives you a concrete offer to work with and prevents the dealer from steering you to an even worse rate.
What is the difference between pre-approval and final approval?
Pre-approval means the lender has reviewed your income and credit and will lend you up to a certain amount, but they have not seen the specific car yet. Final approval happens after you pick a car and provide the VIN — the lender confirms the car's value and that it is worth the loan amount. Pre-approval is usually good for 30 to 60 days. Most of the time, final approval is a formality if nothing has changed.
Should I get pre-approved before I go to the dealership?
Yes, if you have time. Pre-approval tells you your real rate and budget, and it lets you negotiate with the dealer knowing you have another option. It also prevents the dealer from marking up your rate. The only reason not to pre-approve is if you are buying same-day and cannot wait one to three business days.
What if the dealer's rate is higher than my pre-approval?
You can use your pre-approval. Tell the dealer you have an offer from another lender and ask if they can match it. Many dealers will, because they make money on the sale of the car, not just the financing. If they cannot match it, you can walk away and use your pre-approval to buy the car elsewhere or finance it through your original lender.
Can I refinance my car loan later?
Yes. If your credit score improves or interest rates drop, you can refinance through a bank, credit union, or online lender. You will need the current loan balance, the VIN, and proof of insurance. Refinancing usually takes one to three business days and can lower your monthly payment or shorten your loan term.
