What "best" means depends on your credit score and how you plan to use the loan
There is no single best car loan because lenders price loans differently based on your credit history, income, the age of the car, and how long you want to borrow. A loan that carries a low interest rate for someone with excellent credit might not even be available to someone rebuilding credit. The real work is understanding what terms different lenders offer to someone in your specific situation, then comparing those actual offers side by side.
The lenders you can borrow from fall into three categories: banks, credit unions, and captive finance companies (the lending arms of car manufacturers). Each has different underwriting standards and pricing. Banks tend to require higher credit scores. Credit unions often have lower rates for members but may have stricter membership rules. Captive lenders like Ford Credit or Toyota Financial Services sometimes offer promotional rates but may require you to buy their car.
Before you walk into a dealership or contact a lender, you need to know your credit score, how much you can put down, and how long you want the loan to run. These three things determine what you will be offered and what you will pay.
Key Takeaways
- Your credit score is the single biggest factor in the interest rate you receive; scores above 740 typically unlock the lowest rates, while scores below 620 face rates two to four percentage points higher.
- Credit unions often offer lower rates than banks for the same credit profile, but you must be a member and may need to meet income or employment requirements.
- Getting pre-approved by a lender before shopping for a car lets you negotiate the price separately from the financing, and gives you a rate to compare against dealer offers.
- A shorter loan term (36 to 48 months) costs less in total interest but raises your monthly payment; a longer term (60 to 72 months) lowers the payment but increases what you pay overall.
- Dealer financing is convenient but often more expensive than pre-approval from a bank or credit union, because dealers mark up the rate they receive from their lender.
How credit score and loan term affect the rate you receive
Lenders use your credit score as the primary signal of risk. A score of 740 or higher typically qualifies you for the best rates available. Scores between 700 and 739 usually receive rates one to two percentage points higher. Scores between 660 and 699 face rates two to three points higher. Below 660, rates climb steeply, and below 620, many mainstream lenders will not offer a loan at all.
The length of the loan also affects the rate. A 36-month loan carries a lower interest rate than a 60-month loan from the same lender, because the lender's money is at risk for a shorter time. However, the monthly payment on a 36-month loan is higher. A 60-month loan spreads the same amount of money over more months, lowering the payment but increasing the total interest you pay. A 72-month loan does this even more.
The down payment you bring also matters. A larger down payment reduces the amount you need to borrow, which lowers the lender's risk. Putting down 20 percent instead of 10 percent typically improves your rate by a quarter to half a percentage point. It also reduces the chance you will owe more than the car is worth if you need to sell it early.
Banks, credit unions, and captive lenders: where to get pre-approved
A bank is the most straightforward place to start. Most banks offer auto loans to customers and non-customers. You can explore online or in person. Banks typically require a credit score of 660 or higher, though the best rates go to scores above 740. The process takes a few days to a week. Banks do not require you to buy a specific car; you can use the loan to buy any vehicle you choose.
A credit union often offers lower rates than banks for the same credit profile, because credit unions are member-owned and operate on a non-profit basis. However, you must be a member to borrow. Membership requirements vary: some credit unions are open to anyone who lives or works in a certain area, while others require membership in a profession, employer, or organization. If you are already a member, check your credit union's auto loan terms before you shop elsewhere. If you are not a member, joining can take a few days to a week.
A captive lender is the financing company owned by a car manufacturer—Ford Credit, Toyota Financial Services, Honda Financial Services, and so on. These lenders sometimes offer promotional rates (like 0 percent financing) to move inventory, but the promotion usually requires you to buy that manufacturer's car. Captive lenders also tend to have looser credit requirements than banks, which can be useful if your score is below 660. However, their standard rates are often higher than banks or credit unions.
Getting pre-approved before you shop for a car
Pre-approval means a lender has reviewed your financial information and told you the interest rate and loan terms they will offer you. Pre-approval is not a binding commitment, but it is a firm offer. Getting pre-approved before you shop gives you two advantages: you know exactly what you can afford, and you can negotiate the car price separately from the financing.
To get pre-approved, contact a bank or credit union and ask for an auto loan pre-approval. You will need to provide your Social Security number, income, employment history, and details about any debts you carry. The lender will pull your credit report. This takes three to five business days. The lender will then tell you the maximum loan amount, the interest rate, and the loan term they will offer.
Once you have a pre-approval letter, you can walk into a dealership and negotiate the price of the car without worrying about financing. After you agree on a price, you can tell the dealer you have outside financing and close the deal with your pre-approved loan. Some dealers will try to convince you to use their financing instead, often by offering a lower rate. Compare that dealer rate against your pre-approval rate—do not assume the dealer's offer is better just because they say it is.
Comparing dealer financing against pre-approval
Dealer financing is convenient: the dealer arranges the loan, and you sign the papers at the dealership. However, dealer financing is usually more expensive than pre-approval from a bank or credit union. Here is why: the dealer receives a loan from a lender (often a captive lender or a bank), then marks up the interest rate before offering it to you. The markup is called the dealer reserve or dealer participation. A dealer might receive a 5 percent rate from their lender, then offer you 5.5 percent and keep the difference.
Dealers are allowed to mark up rates, and the markup is not hidden—it is part of the loan contract you sign. However, most customers do not realize it is happening. If you have a pre-approval rate of 4.8 percent and the dealer offers you 5.5 percent, you are paying 0.7 percentage points more, which adds hundreds of dollars to the total cost of the loan over its life.
The exception is a promotional rate offered by a captive lender. If Toyota is offering 0 percent financing on a specific model, that rate is real and not marked up by the dealer. However, promotional rates usually come with conditions: you may need to put down a certain amount, or the rate may only explore to a specific trim level or model year.
How loan term affects total cost and monthly payment
Loan term is the number of months you have to repay the loan. Common terms are 36, 48, 60, and 72 months. The longer the term, the lower your monthly payment, but the more interest you pay overall.
| Loan Term | Monthly Payment (on $25,000 at 5%) | Total Interest Paid |
|---|---|---|
| 36 months | $460 | $1,580 |
| 48 months | $556 | $2,688 |
| 60 months | $471 | $3,290 |
| 72 months | $410 | $4,520 |
A 36-month loan costs the least in total interest but requires the highest monthly payment. A 72-month loan spreads the cost over more months, lowering the payment, but you pay significantly more in interest. Most buyers choose a 48 to 60-month term as a middle ground.
One risk of a longer term is being underwater on the loan—owing more than the car is worth. Cars depreciate fastest in the first few years. If you finance a $25,000 car over 72 months and the car is worth $18,000 after three years, you still owe $20,000. If the car is totaled in an accident, your insurance payout may not cover what you owe, and you will be responsible for the difference.
What to look for in loan documents before you sign
Once you have chosen a lender and agreed on terms, you will receive loan documents to sign. Read these documents carefully. The key things to check are the interest rate, the loan term, the monthly payment, and any fees.
The interest rate should match what you were quoted. The loan term should be the number of months you agreed to. The monthly payment should be the amount you calculated. Some loans include a documentation fee or origination fee, which is a one-time charge added to the loan. These fees are legal and common, but they should be disclosed upfront. Do not sign if the rate, term, or payment differs from what you were quoted without a clear explanation.
Check whether the loan allows early payoff without penalty. Most auto loans do, but some older or subprime loans may charge a prepayment penalty if you pay off the loan early. If you think you might pay off the loan early, ask about this before you sign.
Frequently Asked Questions
Does my credit score have to be above 700 to get a car loan?
No. Scores above 700 receive the best rates, but lenders offer loans to scores as low as 580 or 600. Below 620, options narrow and rates climb steeply. Captive lenders and some credit unions are more willing to lend to lower scores than traditional banks.
Should I always choose the shortest loan term to pay less interest?
Not necessarily. A 36-month loan costs less in interest but raises your monthly payment significantly. If a higher payment would strain your budget or force you to skip other bills, a 48 or 60-month term is the better choice. The extra interest is worth the stability of a payment you can afford.
Can I refinance my car loan later if interest rates drop?
Yes. If you have a loan at 6 percent and rates drop to 4 percent, you can refinance by taking out a new loan to pay off the old one. You will pay a small fee to refinance, but if the rate drop is large enough, you will save money. Refinancing works best if you still have a good credit score and the car has not depreciated too much.
What happens if I miss a car loan payment?
Missing one payment typically triggers a late fee and a note on your credit report. Missing multiple payments can lead to repossession, where the lender takes back the car. If you think you will miss a payment, contact your lender when ready—many offer temporary payment deferrals or loan modifications to help borrowers in hardship.
Is it better to finance through the dealer or a bank?
A bank or credit union pre-approval usually offers a lower rate than dealer financing, because dealers mark up the rates they receive. However, dealer financing is more convenient. If the dealer's rate is within 0.5 percentage points of your pre-approval, the convenience may be worth it. If the difference is larger, use your pre-approval.
