Interest rates on car loans are set by the lender, not by a central authority, and they depend on your credit score, the loan term, the vehicle's age, and current market conditions
The rate you're offered on a car loan is not the same rate everyone gets. Banks, credit unions, and dealerships each set their own rates based on how risky they think lending to you is. A person with a credit score of 750 will see a different rate than someone with a score of 650, even if they're borrowing the same amount from the same lender. The rate also changes depending on whether you're buying a new car or a used one, how long you want to take to repay the loan, and what the broader economy is doing at that moment.
Your credit score is the single biggest factor lenders look at. It tells them whether you've paid past debts on time. A higher score signals lower risk, so you get a lower rate. The loan term — how many months you'll take to repay — also matters: a 36-month loan typically carries a lower rate than a 72-month loan, because the lender's money is at risk for less time. The age of the car matters too: lenders charge more to finance a used car than a new one, because used cars lose value faster and are worth less if the lender has to repossess it.
Key Takeaways
- Your credit score is the primary factor that determines your rate; scores above 700 typically unlock rates below 6%, while scores below 620 often see rates above 10%.
- Credit unions and banks usually offer lower rates than dealerships, but you need to check with multiple lenders to compare what each one will actually offer you.
- The loan term you choose affects your rate: shorter terms (36–48 months) usually have lower rates than longer ones (60–72 months).
- New cars typically have lower rates than used cars from the same lender, and rates change month to month based on what the Federal Reserve does with its benchmark rate.
How your credit score determines the rate you see
Lenders pull your credit report and calculate a credit score to predict whether you'll repay the loan. The three major credit bureaus — Equifax, Experian, and TransUnion — each maintain a file on you. Most lenders use a FICO score, which ranges from 300 to 850. The higher your score, the lower your rate.
A score of 750 or above typically qualifies you for rates in the 4% to 6% range at a bank or credit union. A score between 700 and 749 usually sees rates between 5% and 7%. A score between 650 and 699 often results in rates between 7% and 10%. Below 650, rates can climb to 10% or higher. These are rough ranges — the exact rate depends on the lender, the loan term, and the vehicle. The only way to know what you'll actually be offered is to get a rate quote from the lender itself.
You can check your own credit score for free through AnnualCreditReport.com, which is the official site for the three bureaus. Knowing your score before you shop for a loan helps you understand what rate range to expect and whether it makes sense to wait and improve your score before borrowing.
Where to get a rate quote and what to compare
You have three main sources for car loans: banks, credit unions, and dealerships. Banks and credit unions typically offer lower rates than dealerships, but you need to check with each one to see what they'll actually offer you based on your credit and the specific car you want to buy.
Banks include both large national institutions and smaller regional ones. Most have online rate quote tools where you enter basic information — your credit range, loan amount, and term — and get a preliminary rate. This quote is not a commitment; it's an estimate to help you compare. To get a firm rate, you'll need to formally request a loan, which triggers a hard credit pull and a full underwriting process.
Credit unions often have lower rates than banks, but you have to be a member to borrow from them. Membership requirements vary: some are open to anyone in a geographic area, others are limited to employees of a specific company or members of a specific profession. If you're not already a member, check whether you're may be able to access before you spend time on an process. The National Credit Union Administration (NCUA) website has a tool to find credit unions near you and their membership rules.
Dealerships can arrange financing through their own lenders or through banks and credit unions they partner with. Dealership rates are usually higher than what you'd get by going directly to a bank or credit union, because the dealership adds a markup. However, some dealerships offer promotional rates — 0% or 1.9% financing — on certain new cars, usually for buyers with good credit. These deals are real, but they're temporary and limited to specific models.
How loan term affects your rate and total cost
The length of your loan — the term — directly affects both your interest rate and how much you'll pay overall. A shorter term means a lower rate but a higher monthly payment. A longer term means a higher rate but a lower monthly payment.
A 36-month loan typically has the lowest rate. A 48-month loan is slightly higher. A 60-month loan is higher still. A 72-month or 84-month loan usually carries the highest rate. The difference can be significant: a lender might offer 5% on a 36-month loan and 6.5% on a 72-month loan for the same borrower and vehicle.
To understand the real cost, you need to calculate the total interest you'll pay, not just the rate. On a $25,000 loan at 5% for 36 months, you'll pay about $1,950 in interest. The same $25,000 at 6.5% for 72 months costs about $5,400 in interest — nearly three times as much, even though the rate is only 1.5 percentage points higher. Your monthly payment on the 36-month loan would be around $740; on the 72-month loan, around $400. The choice depends on your budget: can you afford the higher monthly payment for a shorter term, or do you need the lower payment even if it costs more overall?
New cars versus used cars and how rates differ
Lenders charge different rates for new and used vehicles because they depreciate at different speeds. A new car loses value quickly in the first year, but the rate of loss slows after that. A used car has already taken the steepest depreciation hit, so it's riskier for the lender to finance.
A new car typically qualifies for a rate 1 to 3 percentage points lower than a used car from the same lender. If a bank offers 5% on a new car, they might offer 7% or 8% on a used car with the same loan term and borrower credit score. The older the used car, the higher the rate. A 2-year-old car might get a 7% rate, while a 5-year-old car might get 9% or higher.
Some lenders have age cutoffs: they won't finance a car older than 10 years, or they require a larger down payment for cars over a certain age. Check with the lender about their used-car policies before you spend time on a quote.
How the Federal Reserve's actions affect rates you see
Car loan rates move up and down based on what the Federal Reserve does with its benchmark interest rate. When the Fed raises its rate, banks' costs go up, and they pass those costs to borrowers by raising car loan rates. When the Fed lowers its rate, car loan rates typically fall too, though not always when ready and not always by the same amount.
You can't control what the Fed does, but you can track its decisions to understand whether rates are likely to rise or fall in the coming months. The Federal Reserve's website publishes its meeting schedule and decisions. Financial news outlets cover Fed announcements the day they happen. If the Fed is raising rates, locking in a rate quote sooner rather than later makes sense. If the Fed is pausing or cutting rates, waiting a few weeks might get you a better offer.
That said, the difference between checking rates this week and next week is usually small — a few tenths of a percentage point at most. Don't delay a purchase you need to make just waiting for a rate drop. The bigger factor is your own credit score and the term you choose.
Frequently Asked Questions
What credit score do I need to get a good car loan rate?
A score of 700 or above typically unlocks rates below 7% at a bank or credit union. Scores between 650 and 700 usually see rates between 7% and 10%. Below 650, rates climb quickly. If your score is below 650, you might consider waiting a few months to improve it before borrowing, or exploring a co-signer option.
Should I get a rate quote from a dealership or go directly to a bank?
Go directly to a bank or credit union first to see what rate they'll offer you. Write down that rate. Then, if you're buying from a dealership, ask them what rate they can offer. Compare the two. Dealership rates are usually higher, but occasionally a promotional rate beats what the bank offered. You're not obligated to use the dealership's financing.
Does shopping around for rates hurt my credit score?
Multiple rate inquiries from different lenders within a 14-to-45-day window typically count as a single inquiry on your credit report, so shopping around doesn't significantly damage your score. However, each lender does a hard pull, which temporarily lowers your score by a few points. The impact is small and temporary, and it's worth it to compare rates.
Is a 0% car loan rate real, or is there a catch?
Zero-percent financing is real, but it's limited to new cars, usually specific models, and usually requires good credit (typically 700 or above). The dealership or manufacturer is absorbing the interest cost as a promotion. You're not getting a hidden fee elsewhere — you're genuinely paying no interest. However, the car's price might be higher than it would be if you negotiated a discount instead of taking the 0% rate.
What happens to my rate if I pay off the loan early?
Most car loans have no prepayment penalty, so you can pay off the loan early without extra fees. Paying early saves you interest because you're not paying interest for the full term. However, your interest rate itself doesn't change — it stays the same for the life of the loan. The savings come from paying less total interest, not from a rate reduction.
