The best car loan depends on your credit score, down payment, and how long you want to pay
There is no single "best" car loan because what works depends on your financial position. A borrower with a 750 credit score and 20 percent down will get different offers than someone with a 620 score and no down payment — and the loan that costs less overall may not be the one with the lowest monthly payment. The real choice is between lenders (banks, credit unions, dealerships, online lenders) and between loan terms (how many months you borrow for, what interest rate you lock in, whether you can pay early without penalty).
Your starting point is knowing your credit score before you shop. You can check it free through AnnualCreditReport.com or through your bank or credit card issuer. Lenders use this score to decide whether to lend to you and at what rate. A higher score typically means a lower interest rate, which saves you thousands over the life of the loan. If your score is below 620, some lenders will still work with you, but you will pay more in interest.
Key Takeaways
- Your credit score is the single biggest factor in what interest rate you will be offered, so check it before you start shopping with lenders.
- Credit unions often offer lower rates than banks or dealerships, especially if you have been a member for a while, but you must be a member to borrow.
- Getting pre-approved by a bank or credit union before you visit a dealership lets you negotiate the car price separately from the loan terms.
- A shorter loan term (36 or 48 months) costs less in total interest than a longer one (60 or 72 months), even though the monthly payment is higher.
- Dealership financing can be convenient but usually carries a higher rate than pre-approval from a bank or credit union, unless the dealer is running a promotional offer.
Credit unions typically offer the lowest rates if you are a member
Credit unions are member-owned financial institutions that often lend at lower rates than banks or dealerships. If you belong to one — through your employer, your school, your union, or your community — you can ask about auto loan rates before you shop for a car. Many credit unions let you get pre-approved online or by phone in a few minutes.
The catch is that you must be a member to borrow. If you are not, you may be able to join by opening a savings account (sometimes for as little as $5 or $25) or by meeting other membership criteria. Some credit unions have a waiting period before you can borrow after joining, so check your union's rules. If you are already a member, a credit union loan is often worth comparing because the rates are usually lower than what a bank or dealership will offer.
Banks offer competitive rates if you have good credit and an existing relationship
Traditional banks — Chase, Bank of America, Wells Fargo, and regional banks — offer car loans, and many will pre-approve you online. If you already have a checking or savings account with the bank, you may get a slightly better rate than a new customer would. Banks typically require a credit score of 650 or higher for their best rates, though some will lend to borrowers with lower scores at a higher rate.
The advantage of a bank loan is that you can lock in the rate before you go to the dealership. This means you know exactly what your monthly payment will be and you can negotiate the car price without the dealer trying to adjust the financing terms. You will need to provide proof of income (a recent pay stub or tax return), proof of residence, and details about the car you plan to buy (or a general loan amount if you have not picked one yet).
Online lenders work with a wider range of credit scores but charge higher rates
Online lenders like LendingClub, Upstart, and Lightstream offer car loans to borrowers with credit scores as low as 580 or 600. They typically approve you faster than a bank — sometimes in hours — and the process is entirely online. If you have fair or poor credit and cannot get approved by a bank or credit union, an online lender may be your only option.
The trade-off is that online lenders charge higher interest rates than banks or credit unions, especially for borrowers with lower credit scores. A borrower with a 650 credit score might pay 8 to 12 percent interest through an online lender, compared to 5 to 7 percent through a bank or credit union. Over a five-year loan, that difference adds up to hundreds or thousands of dollars. Before you accept an online lender's offer, compare it to what a credit union or bank will charge, even if you think you will not be approved.
Dealership financing is convenient but usually more expensive
When you finance through the dealership, the dealer arranges the loan with a bank or finance company on your behalf. The advantage is convenience — you can pick out the car, negotiate the price, and arrange financing all in one place. The disadvantage is that dealership loans almost always carry a higher interest rate than pre-approval from a bank or credit union.
Dealerships make money by marking up the interest rate. If a lender approves you at 6 percent, the dealer might offer you 7 or 8 percent and keep the difference. There are exceptions: some dealers run promotional financing (0 percent for 60 months, for example) to move inventory, and these can be genuinely competitive. But promotional rates usually require excellent credit and a large down payment, and they are not available on every vehicle.
If you do finance through a dealership, get a pre-approval from a bank or credit union first. You can tell the dealer, "I have been pre-approved at 6 percent — can you beat that?" This forces the dealer to compete rather than straightforward offering whatever rate they want.
Loan term length determines your monthly payment and total cost
Car loans typically run for 36, 48, 60, or 72 months. A longer term means a lower monthly payment but more interest paid overall. A shorter term means a higher monthly payment but less interest paid overall.
| Loan Term | Monthly Payment (on $25,000 at 6%) | Total Interest Paid |
|---|---|---|
| 36 months | $738 | $1,568 |
| 48 months | $575 | $2,600 |
| 60 months | $483 | $3,798 |
| 72 months | $418 | $5,096 |
The difference between a 36-month and 72-month loan on the same car is more than $3,500 in interest. If you can afford the higher monthly payment, a shorter term saves you money. However, if a shorter term would strain your budget, a longer term is reasonable — the goal is to borrow an amount you can actually repay without falling behind on other bills.
Some lenders allow you to pay off the loan early without penalty. If early payoff is an option, you could take a 60-month loan but pay it off in 48 months if your financial situation improves. Always ask whether there is a prepayment penalty before you sign.
Down payment size affects your interest rate and monthly payment
A larger down payment lowers the amount you need to borrow, which reduces your monthly payment and the total interest you pay. It also signals to lenders that you are serious about the purchase, which can result in a lower interest rate. Most lenders prefer a down payment of at least 10 to 20 percent of the car's price.
If you have less than 10 percent to put down, you will likely pay a higher interest rate and may have trouble getting approved by a bank or credit union. If you have no down payment, online lenders and some dealerships will still work with you, but the rate will be higher. Saving up for a larger down payment before you buy can save you hundreds in interest.
How to compare loan offers side by side
Once you have pre-approval offers from at least two lenders, compare them using the same criteria: the interest rate, the loan term, the monthly payment, and the total amount you will pay over the life of the loan. Do not focus only on the monthly payment — a lower payment often means you are paying more interest overall.
Ask each lender for a Loan Estimate or Truth in Lending disclosure. This document shows the interest rate, the finance charge (total interest), the payment schedule, and any fees. By law, lenders must provide this before you sign. Use it to compare apples to apples.
Also check whether the lender allows you to pay off the loan early without penalty, and whether the rate is fixed (stays the same for the entire loan) or variable (can change). For car loans, fixed rates are standard and preferable because your payment will not surprise you.
Frequently Asked Questions
Should I get pre-approved before I go to the dealership?
Yes. Pre-approval from a bank or credit union gives you a firm interest rate and lets you negotiate the car price separately from the financing. It also gives you leverage to negotiate with the dealer. Without pre-approval, the dealer controls both the price and the financing terms, which usually costs you more.
What credit score do I need to get a car loan?
Most banks and credit unions prefer a score of 650 or higher for their best rates. Credit unions sometimes work with scores as low as 600. Online lenders and some dealerships will lend to borrowers with scores below 600, but the interest rate will be significantly higher. Check your score before you shop so you know what to expect.
Is it better to have a co-signer on my loan?
A co-signer with good credit can help you get approved and may lower your interest rate, especially if your credit is fair or poor. However, the co-signer is legally responsible for the loan if you do not pay, so make sure they understand the commitment. Some lenders allow you to remove a co-signer after you have made a certain number of on-time payments.
Can I refinance my car loan later if interest rates drop?
Yes. If interest rates fall or your credit score improves, you can refinance with a different lender to get a lower rate. Refinancing means taking out a new loan to pay off the old one. You will save money only if the new rate is significantly lower and you keep the car long enough to recoup any fees involved in refinancing.
What happens if I miss a car loan payment?
Missing a payment will damage your credit score and may result in late fees. If you miss multiple payments, the lender can repossess the car. If you are struggling to make payments, contact your lender when ready — many will work with you on a temporary payment reduction or deferment rather than let the loan go into default.
