Used auto loan rates depend on your credit score, the lender type, and how long you finance the car
The lowest rates available to you are not the same as the lowest rates advertised. Banks, credit unions, and online lenders all post different rates for different borrowers. A rate of 4.5% at one lender might be 7.2% at another — the difference is usually your credit score, income, and how much you put down.
Credit unions typically offer the lowest rates overall, especially if you are a member. Banks come next, followed by dealership financing and buy-here-pay-here lots. Online lenders fill the gap for people with lower credit scores, but their rates are higher. The length of your loan also matters: a 36-month loan usually carries a lower rate than a 72-month loan from the same lender, because the lender's risk is lower.
The only way to know what rate you personally may have access to for is to get quotes from multiple lenders. This takes 15 to 30 minutes per lender and does not hurt your credit score if you do it within 14 days — the credit bureaus count multiple auto loan inquiries as a single search.
Key Takeaways
- Credit unions almost always have lower rates than banks and dealerships, but you must be a member or join one before you borrow.
- Your credit score is the single biggest factor in the rate you receive; a score above 700 usually unlocks rates below 6%, while scores below 600 often see rates above 10%.
- Comparing quotes from at least three lenders takes less than an hour and can save you thousands in interest over the life of the loan.
- The dealership's financing offer is rarely the lowest rate available, even if the dealer claims it is a special offer.
- Putting down 20% or more of the car's price typically lowers your rate by 0.5% to 1.5% compared to a smaller down payment.
Credit unions usually have the lowest rates for used auto loans
If you belong to a credit union, start there. Credit unions are member-owned cooperatives that lend money to their own members at lower rates than banks can offer. Used auto loan rates at credit unions typically range from 3.5% to 8%, depending on your credit score and the age of the vehicle. Some credit unions specialize in used cars and have rates even lower than that.
You do not have to be a member to join most credit unions. Membership requirements vary — some are based on where you work, others on where you live, and some accept anyone. Joining usually takes 10 to 15 minutes online and costs nothing. Once you are a member, you can explore for a loan when ready.
If you do not currently belong to a credit union, search for one in your area using the CO-OP Network or Alliant Credit Union's locator tool. Call the credit union and ask about used auto loan rates before you join; some credit unions have age limits on the vehicles they will finance (for example, no cars older than 10 years), and you want to know that before you explore.
Banks offer lower rates than dealerships but higher than credit unions
Traditional banks like Wells Fargo, Chase, and Bank of America offer used auto loans with rates typically between 5% and 10%, depending on your credit score. Banks require a credit score of at least 600 to 650 for approval, and rates drop significantly if your score is above 700. You can get a quote online in minutes without visiting a branch.
Banks also require proof of income, a valid driver's license, and proof of insurance before they fund the loan. The approval process usually takes one to three business days. Banks will finance used cars up to 10 years old, though some have stricter age limits. Ask about the specific vehicle before you explore — banks sometimes decline loans on cars with high mileage or known mechanical issues.
One advantage of bank financing is that you can shop for the car first, then explore for the loan once you have found one. The bank will then contact the dealership directly to arrange payment. This gives you time to negotiate the car's price separately from the financing.
Online lenders work faster but charge higher rates
Online lenders like LendingClub, Upstart, and Elevate approve loans in hours rather than days, and some will finance cars with lower credit scores than banks require. Rates at online lenders typically range from 6% to 16%, with the highest rates going to borrowers with credit scores below 600.
The speed comes with a trade-off: online lenders charge more because they take on more risk. They also often require you to already own the car before you explore — you cannot use their loan to buy a car from a dealership the way you can with a bank or credit union. This means you would need to buy the car with cash or another loan first, then refinance it with the online lender.
Online lenders are most useful if you have a lower credit score and need money quickly, or if you are refinancing a loan you already have. If you have decent credit and time to wait a few days, a bank or credit union will almost always be cheaper.
Dealership financing is convenient but rarely the cheapest option
Dealerships offer financing through captive lenders — finance companies owned by the car manufacturer. Ford Credit, GM Financial, and Toyota Financial Services are examples. Dealership rates typically range from 4.9% to 12%, depending on your credit score and the manufacturer's current incentives.
Dealership financing is convenient because you handle everything in one place: you pick the car, negotiate the price, and sign the loan papers all at the same desk. The dealership also handles the title and registration paperwork. Approval usually takes an hour or two.
The catch is that dealership rates are rarely the lowest available. The dealership's job is to make money on the financing, so they mark up the rate they receive from the lender. Even if the dealership says the rate is a "special offer," you should still compare it to quotes from at least one bank or credit union. A difference of 1% or 2% adds hundreds or thousands of dollars to what you pay over the life of the loan.
Your credit score is the biggest factor in the rate you receive
Lenders use your credit score to decide how much risk you represent. A higher score means you have a history of paying bills on time, so the lender charges you less. A lower score means more risk, so the lender charges more to protect themselves.
Here is how credit scores typically map to rates across most lenders:
| Credit Score Range | Typical Rate Range | Typical Monthly Payment on $20,000 Loan (60 months) |
|---|---|---|
| 750+ | 3.5% to 5.5% | $360 to $380 |
| 700–749 | 5.5% to 7.5% | $380 to $410 |
| 650–699 | 7.5% to 10% | $410 to $450 |
| 600–649 | 10% to 13% | $450 to $500 |
| Below 600 | 13% to 18%+ | $500+ |
If your credit score is below 700, you have options to lower your rate before you explore. Paying down existing debt, correcting errors on your credit report, and waiting a few months for negative marks to age can all improve your score. Even a 20-point improvement can lower your rate by 0.5% to 1%.
How to compare rates and find the lowest option for your situation
Start by checking your credit score for free using AnnualCreditReport.com or a service like Credit Karma. This tells you what rate range to expect. Then get quotes from at least three lenders: one credit union, one bank, and one online lender. You can do this in one afternoon.
When you request a quote, provide the same information to each lender: the year and mileage of the car you want to buy, how much you plan to put down, and how long you want to finance it. This makes the quotes comparable. Most lenders will give you a rate quote without a hard credit inquiry, so you can shop around without damaging your score.
Once you have three quotes, compare the total interest you will pay over the life of the loan, not just the interest rate. A 5% loan for 72 months might cost more in total interest than a 6% loan for 48 months, even though the rate is lower. Use an auto loan calculator to see the total cost of each option.
After you choose a lender, you can usually lock in your rate for 30 to 60 days while you find the right car. This protects you if rates rise before you are ready to buy.
Frequently Asked Questions
Does shopping for rates hurt my credit score?
Multiple auto loan inquiries within 14 days count as a single search on your credit report, so they have minimal impact on your score. Shopping around is worth it — the rate difference between lenders can save you thousands of dollars.
Should I get preapproved before I go to the dealership?
Yes. Preapproval from a bank or credit union gives you a firm rate and a maximum loan amount before you shop. You can then negotiate the car's price separately from the financing, and you are not pressured to accept the dealership's rate.
What if I have bad credit and cannot get approved anywhere?
Buy-here-pay-here lots and some online lenders will finance people with very low credit scores, but rates are typically 15% to 29%. Before you go this route, try a credit union that specializes in second-chance lending, or ask a family member to cosign the loan with you.
Can I refinance my used auto loan later if rates drop?
Yes. If interest rates fall after you take out your loan, you can refinance with a different lender. Refinancing makes sense if the new rate is at least 1% lower than your current rate and you have at least two years left on the loan.
Does the age of the car affect the rate I receive?
Yes. Newer used cars (typically 5 years old or newer) may have access to for lower rates because they are more reliable and hold their value better. Cars older than 10 years usually have higher rates or may not may have access to at all, depending on the lender.
