The main places to borrow for a car
You can get a car loan from a bank, a credit union, an online lender, or the car dealership itself. Each charges different interest rates and has different speed and flexibility. Banks and credit unions typically offer the lowest rates if your credit is good, but take longer to process. Online lenders move faster and may accept lower credit scores, but charge more interest. Dealership financing is the quickest but almost always the most expensive.
The rate you actually pay depends on your credit score, how much you put down, how long you borrow for, and what you're buying. A used car from a private seller costs more to finance than a new car from a dealer, because lenders see it as riskier. A $10,000 loan at 5% costs you less total interest than the same loan at 8%, even though the monthly payment difference might be only $30 or $40.
Key Takeaways
- Banks and credit unions offer the lowest interest rates but require you to explore before you shop, which takes three to seven days.
- Online lenders fund loans in one to three days and accept credit scores that banks reject, but charge 2 to 4 percentage points more in interest.
- Dealership financing approves you on the lot in minutes but typically costs 1 to 3 percentage points more than a bank loan for the same borrower.
- Your monthly payment and total cost depend on the interest rate, how much you borrow, and how long you take to repay — a longer loan lowers the monthly payment but raises the total interest you pay.
- Getting pre-approved by a bank or credit union before you shop gives you a firm rate and lets you negotiate with the dealer from a position of strength.
Banks and credit unions: lowest rates, slower process
Banks and credit unions offer the lowest interest rates because they lend money cheaply and have strict underwriting. You explore online or in person, provide pay stubs and bank statements, and wait three to seven days for a decision. If approved, they send you a check or deposit the money directly, and you use it to buy the car from any seller — dealer or private.
Credit unions typically beat banks by 0.5 to 1 percentage point because they're member-owned and don't answer to shareholders. You must be a member to borrow, but membership is often free or costs $25 to $50 one time. If you're not already a member, joining takes 10 minutes online for most credit unions.
The tradeoff is time. You can't walk into a dealership and drive off the same day. You explore first, get approved, receive the funds, then go shopping. This means you know your budget and your rate before you negotiate, which is an advantage — dealers can't pressure you into their financing because you already have money.
Online lenders: faster approval, higher rates
Online lenders like LendingClub, Upgrade, and Lightstream fund loans in one to three business days and accept credit scores as low as 580 to 620. You explore on their website, upload documents by phone camera, and get a decision the same day or next morning. The money lands in your bank account within 24 hours of approval.
The cost is higher. Online lenders charge 2 to 4 percentage points more than banks for the same borrower. A borrower with a 700 credit score might pay 5% at a credit union and 8% at an online lender. Over a five-year loan, that difference adds up to $1,500 to $2,000 in extra interest on a $25,000 car.
Online lenders make sense when you need money fast and banks have turned you down, or when your credit is below 650. They also let you borrow for used cars from private sellers, which some banks won't do. Read the terms carefully — some online lenders charge a prepayment penalty if you pay off the loan early, which means you can't refinance later if your credit improves.
Dealership financing: when ready approval, highest cost
Dealership financing approves you on the lot in 15 minutes and lets you drive home the same day. The dealer's finance manager runs your credit, you sign papers, and you own the car. This speed comes at a price: dealership rates are typically 1 to 3 percentage points higher than what you'd pay at a bank for the same credit score.
Dealerships also make money by marking up the rate. If the bank approves you at 6%, the dealer might offer you 7.5% and keep the 1.5% difference. You don't see this markup — it's built into the monthly payment the dealer quotes you. This is why getting pre-approved elsewhere before you shop is so powerful: you know the real rate, and you can tell the dealer "I have financing at 6%, so you need to beat that."
Dealership financing is useful only when you have no other option — your credit is very poor, you need a car today, or you're buying a rare used car that requires when ready payment. Otherwise, the extra cost over five years usually exceeds $1,000.
How interest rates and loan terms affect what you pay
Your monthly payment depends on three things: the loan amount, the interest rate, and the number of months. A $25,000 car at 5% for 60 months costs $471 per month. The same car at 8% costs $608 per month — $137 more every month, or $8,220 more over the life of the loan.
Longer loans lower the monthly payment but raise the total interest. A $25,000 loan at 6% costs $483 per month for 60 months (total interest: $3,980) or $402 per month for 72 months (total interest: $5,944). You save $81 per month but pay $1,964 more in interest. Most lenders offer 48 to 84 months; anything longer than 72 months usually means you're underwater — owing more than the car is worth — for most of the loan.
The interest rate matters more than the term. A 1 percentage point difference costs you $1,200 to $1,500 on a $25,000 loan over five years. This is why shopping around for the best rate saves real money. Getting pre-approved by two or three lenders and comparing their offers takes an hour and can save you thousands.
What lenders look at when they decide your rate
Your credit score is the biggest factor. Scores above 750 get the best rates. Scores between 700 and 749 get standard rates. Scores between 650 and 699 pay 1 to 2 percentage points more. Below 650, rates jump sharply, and some lenders won't touch you at all. You can check your credit score free at annualcreditreport.com or creditkarma.com.
Your down payment matters second. Putting down 20% instead of 10% lowers your rate by 0.25 to 0.5 percentage points because the lender's risk is smaller. The car's age and mileage also affect the rate — new cars get better rates than used, and used cars under 100,000 miles get better rates than high-mileage ones. Your income and debt-to-income ratio matter too. If you already owe $800 per month and earn $4,000, lenders see you as stretched thin and charge more.
Comparing offers and choosing the right lender
Get pre-approved by at least two lenders before you shop. This takes 20 minutes per lender and gives you a firm rate and loan amount. Write down the rate, the term, any fees, and whether there's a prepayment penalty. Compare the total cost, not just the monthly payment — a lower rate for 60 months usually beats a higher rate for 72 months.
When you're at the dealership, tell the finance manager your pre-approved rate. Many dealers will match or beat it to earn your business. If they can't, you already have money lined up and can walk away. Never let a dealer pressure you into their financing by saying "let's see what we can do" — you've already seen what you can do, and you know the real cost.
If you're buying from a private seller, you must have financing lined up before you make an offer. Private sellers won't hold a car while you explore for a loan. Banks and online lenders both work for private-party purchases, but dealership financing does not — the dealer needs to be involved to register the lien.
Frequently Asked Questions
Does getting pre-approved hurt my credit?
A pre-approval triggers a hard inquiry, which lowers your score by a few points for a few months. Multiple inquiries from different lenders within 14 days count as one inquiry, so shop around without penalty. Avoid explore to many lenders over weeks or months — each new inquiry stacks.
What if I have bad credit or no credit history?
Online lenders and some credit unions work with credit scores below 650. You'll pay higher rates, typically 10% to 15%, and may need a larger down payment or a co-signer. Credit unions sometimes offer credit-builder loans that help you build history while you borrow. Dealership financing is also an option, though rates are usually highest here too.
Can I refinance my car loan later?
Yes, if your credit improves or rates drop. You can refinance through a bank, credit union, or online lender after six months to a year. Refinancing to a lower rate saves money; refinancing to a longer term lowers your payment but costs more in interest. Check whether your current loan has a prepayment penalty before you refinance.
What's the difference between a fixed rate and a variable rate?
Almost all car loans are fixed-rate, meaning your interest rate and monthly payment never change. Variable-rate car loans are rare and usually a bad deal — your payment could jump if rates rise. Stick with fixed-rate loans.
Should I pay cash or finance a car?
If you have the cash and the interest rate is below 4%, financing usually makes sense because you can invest the cash and earn more than you pay in interest. If rates are above 6% or you'd drain your emergency fund to pay cash, keep the cash and finance the car. Never borrow at 10% to pay cash for a depreciating asset.
