Used car loan rates depend on your credit score, the car's age and mileage, and the lender you choose
A used car loan rate is the percentage of the loan amount you pay back as interest each year. The rate you receive is not set by law — it changes based on who you borrow from, how creditworthy you appear to them, and what you are borrowing to buy. A car that is five years old will typically carry a higher rate than a three-year-old car from the same lender, because older cars are riskier collateral. Your credit score is usually the single biggest factor: someone with a score above 750 might receive a rate around 4% to 6%, while someone with a score below 620 might see 12% to 18% or higher, depending on the lender and the vehicle.
The rate you see advertised is almost never the rate you will receive. Banks, credit unions, and dealerships all quote rates based on assumptions about who you are. Your actual rate depends on a conversation with the lender — they will pull your credit report, verify your income, and look at the specific car you want to buy. This is why shopping around matters: the same person can receive different offers from three different lenders.
Key Takeaways
- Used car loan rates typically range from 4% to 18% depending on credit score, but the exact rate you receive comes from the lender after they review your finances and the vehicle.
- Older and higher-mileage cars carry higher rates than newer ones because they are worth less and break down more often, making them riskier for the lender.
- Credit unions often offer lower rates than banks and dealerships, especially for people with fair or good credit, so checking your local credit union is worth the time.
- The loan term you choose — how many months you take to repay — affects both your monthly payment and the total interest you pay over the life of the loan.
- Getting pre-approved for a loan before you shop for a car gives you a real rate offer and lets you negotiate with the dealer from a position of strength.
How your credit score shapes the rate you receive
Lenders use your credit score as a shorthand for how likely you are to repay the loan on time. The three major credit bureaus — Equifax, Experian, and TransUnion — calculate your score based on your payment history, how much debt you already carry, how long you have had credit accounts open, and a few other factors. Most auto lenders use the FICO score, which ranges from 300 to 850.
The relationship between score and rate is not linear. A person with a score of 720 might receive a rate 2 percentage points lower than someone with a 680 score, but the gap between 620 and 580 might be 4 percentage points. This is because lenders see the risk as increasing sharply once you fall below certain thresholds. If your score is below 620, some lenders will decline to lend to you at all, or will require a co-signer or a larger down payment.
You can check your own credit score for free through AnnualCreditReport.com, which is the only site authorized by federal law to provide free reports from all three bureaus. Knowing your score before you talk to a lender removes the surprise and lets you decide whether to shop around or accept the first offer you receive.
Why the car's age and mileage matter to lenders
A used car is collateral for the loan — if you stop paying, the lender can repossess it and sell it to recover their money. An older car with high mileage is worth less and is more likely to break down, so it is a weaker may provide. A lender will charge you more interest to offset that risk.
Most lenders draw a line around 100,000 miles or 10 years of age. A car below that threshold might receive a standard rate; a car above it might see a rate bump of 1 to 3 percentage points. Some lenders will not finance cars older than 12 or 15 years, or with mileage above 150,000 miles, regardless of your credit score. A few lenders specialize in older vehicles but charge significantly higher rates to compensate.
This is one reason why a newer used car — say, a three-year-old model instead of a seven-year-old one — can actually save you money even if the purchase price is higher. The lower interest rate on the newer car can offset the higher principal amount you are borrowing.
Where to shop for used car loan rates
Banks, credit unions, and dealerships all offer auto loans, and they do not all charge the same rate. Credit unions typically offer the lowest rates, especially for members with fair or good credit. Banks offer middle-ground rates and are more likely to work with people who have lower credit scores. Dealerships offer the most convenience — you can finance the car on the lot — but their rates are usually higher because they are marking up the loan or selling it to a bank after you sign.
Getting pre-approved by a bank or credit union before you shop gives you a real rate offer based on your actual finances. You can then walk into a dealership knowing exactly how much you can borrow and at what rate, which puts you in a stronger negotiating position. If the dealer offers you a better rate, you can take it; if not, you already have a backup plan.
To compare rates, contact at least two or three lenders. Each will pull your credit report, which creates a small temporary dip in your score, but multiple inquiries within 14 days of each other count as a single inquiry for scoring purposes. This means you can shop around without damaging your credit.
How loan term affects your rate and monthly payment
The loan term is how many months you have to repay the loan — typically 36, 48, 60, or 72 months. A shorter term means higher monthly payments but lower total interest. A longer term means lower monthly payments but higher total interest. Lenders often charge slightly different rates depending on the term you choose.
A 48-month loan might carry a rate of 6%, while a 72-month loan on the same car might be 6.5%, because the lender is taking on more risk over a longer period. However, the monthly payment difference can be substantial. On a $20,000 loan at 6%, a 48-month term costs about $461 per month, while a 72-month term costs about $333 per month — a $128 difference. Over the full 72 months, you pay about $3,900 more in interest than you would on the 48-month loan.
The right term depends on your budget and how long you plan to keep the car. If you can afford the higher payment and plan to drive the car for many years, a shorter term saves money. If you need the lowest possible monthly payment or plan to trade the car in within a few years, a longer term might make sense despite the extra interest.
Getting pre-approved and what to expect
Pre-approval means a lender has reviewed your finances and offered you a loan at a specific rate, for a specific amount, for a specific term. It is not a may provide — the lender can still back out if your credit score drops or your employment changes before you close the loan — but it is a real offer, not a quote.
To get pre-approved, contact a bank or credit union and provide your name, address, Social Security number, employment information, and income. They will pull your credit report and usually give you an answer within a day or two. The pre-approval letter will state the maximum loan amount, the rate, and the term. You can then use that letter to shop for a car within those parameters.
Pre-approval also protects you at the dealership. Some dealers use a practice called "spot delivery," where they let you drive the car home before the financing is finalized, then call you back days later to say the financing fell through and demand a higher rate or a larger down payment. If you arrive with a pre-approval from another lender, the dealer has less leverage to pressure you into accepting worse terms.
What affects your rate beyond credit score and car age
Lenders also consider your debt-to-income ratio — how much you already owe compared to how much you earn. If you are carrying high credit card balances or have other loans, a lender might offer you a higher rate or decline to lend to you at all. Stable employment and a longer time at your current job can work in your favor. Some lenders offer slightly lower rates to people who set up automatic payments from a bank account.
The size of your down payment also matters. A larger down payment means you are borrowing less, which is less risky for the lender. Putting down 20% instead of 10% might lower your rate by 0.5 percentage points. A down payment also reduces the amount of interest you pay over the life of the loan, so it is worth saving for if you can.
Geography can play a small role. Some lenders operate only in certain states, and state laws vary on how much interest a lender can charge. This is rarely the dominant factor, but it is one reason why rates vary even among people with identical credit scores buying identical cars.
Frequently Asked Questions
What is a good interest rate for a used car loan?
A good rate depends on your credit score and the car's age. If your score is above 700 and the car is less than five years old, a rate below 6% is competitive. If your score is between 650 and 700, expect 7% to 10%. Below 650, rates typically climb to 12% or higher. Compare offers from at least two lenders to know whether you are getting a good deal.
Can I get a lower rate if I pay a larger down payment?
Yes, usually by 0.25 to 0.5 percentage points. A larger down payment reduces the lender's risk because you are borrowing less and have more of your own money at stake. It also reduces the total interest you pay over the life of the loan, so it is a double benefit if you can afford it.
Should I finance through the dealership or get pre-approved elsewhere first?
Get pre-approved first. You will know your real rate and can compare it to what the dealer offers. If the dealer's rate is worse, you can decline and use your pre-approval. If the dealer matches or beats it, you can choose the more convenient option. Pre-approval takes a few days but gives you negotiating power.
Does shopping around for rates hurt my credit score?
Multiple inquiries within 14 days count as a single inquiry for credit scoring purposes, so shopping around has minimal impact. Each inquiry might lower your score by a few points temporarily, but the effect fades within a few months. The benefit of finding a lower rate far outweighs the small, temporary score dip.
What if I have a co-signer — does that change my rate?
Yes. A co-signer with a higher credit score can help you receive a lower rate or borrow more money. The co-signer is legally responsible for the loan if you do not pay, so choose someone you trust and make sure they understand the commitment before they sign.
