How this article was made: Drafted with AI assistance, then checked line by line against the primary sources listed at the end of this page (the CFPB's auto loan answers, the FTC's car financing and used-car guides, NCUA rate data, the Federal Reserve's G.19 release, the IRS fact sheet on the car loan interest deduction, and the NMVTIS vehicle history site), fetched on October 10, 2026. Worked examples use simple illustrative numbers, not real accounts. Rules and company policies change, so re-check the linked sources before you act.

Should you finance a new car or a used one? The usual advice is that new cars get better loan rates and used cars cost less. Both can be true at the same time, which is why the answer depends on the total cost of each loan, not on the rate or the payment alone.

This guide explains how lenders price new and used car loans, what recent national rate data show, how to compare the two on equal terms, and which extra checks matter when the car is used. The worked examples use illustrative numbers. The rules and data come from the Consumer Financial Protection Bureau (CFPB), the Federal Trade Commission (FTC), the National Credit Union Administration (NCUA), the Federal Reserve, and the IRS.

New vs used car loans at a glance

At-a-glance comparison of financing a new car versus a used car: new cars often get lower rates and manufacturer offers but cost more and lose value quickly, while used cars cost less to buy but often carry somewhat higher rates and need more checks

The loan itself works the same way either way: you borrow an amount financed, pay interest at an APR, and repay over a term. What changes is the price of the car, the rate lenders tend to offer, the deals available, and how much risk you take on with the vehicle itself.

Why lenders price new and used loans differently

The CFPB lists the factors auto lenders generally use to set your rate: your credit scores and history, your income and debts, the amount of the loan, the loan term, your down payment compared with the vehicle's value, and the type of vehicle and whether you are purchasing a new or used vehicle. In other words, new or used is one input among several, and your own credit profile often matters more.

The CFPB also explains risk-based pricing: lenders offer less favorable terms, such as a higher rate, to borrowers they consider higher risk, based on information in a credit report or application. If a lender gives you worse terms because of your credit report, you should receive a risk-based pricing notice.

What national rate data show

Bar chart of national average 48-month car loan rates on December 26, 2025 from NCUA: credit union new car 5.32 percent, credit union used car 5.53 percent, bank new car 7.33 percent, bank used car 7.73 percent

The NCUA publishes national average loan rates at credit unions and banks, using data from S&P Global Market Intelligence. Its latest table (2025 Q4, rates for December 26, 2025) showed:

Loan	Credit unions	Banks
New car, 48 months	5.32%	7.33%
Used car, 48 months	5.53%	7.73%
New car, 60 months	5.44%	7.41%
Used car, 36 months	5.41%	7.69%

Two patterns stand out. For the same 48-month term, the average used-car rate was a little higher than the new-car rate at both credit unions and banks. And in this data the gap between institution types was larger than the gap between new and used. For a more recent read on new-car loans, the Federal Reserve's G.19 release (edition covering August 2026) showed commercial bank rates averaging 7.54% on 60-month new-car loans in August 2026. These are averages; your quote can be well above or below them. Our guide to credit unions vs banks explains membership and other differences.

Compare total cost, not just the rate

A slightly higher rate on a much smaller loan can still cost less in dollars. Here is an illustrative comparison with $4,000 down in each case and a 60-month term:

New car: $34,000 price, $30,000 financed at 6.5% APR
Used car (a few years old, similar model): $24,000 price, $20,000 financed at 7.5% APR, or at 8.5% if your quote comes in higher

Illustrative bar chart of monthly payments: a 30,000 dollar new-car loan at 6.5 percent for 60 months costs about 587 dollars a month, a 20,000 dollar used-car loan at 7.5 percent for 60 months about 401 dollars, and the same used loan at 8.5 percent about 410 dollars

Loan	Monthly payment	Total interest	Total of payments
New: $30,000 at 6.5%	about $587	about $5,219	about $35,219
Used: $20,000 at 7.5%	about $401	about $4,046	about $24,046
Used: $20,000 at 8.5%	about $410	about $4,620	about $24,620

Illustrative bar chart of total interest: about 5,219 dollars on a 30,000 dollar new-car loan at 6.5 percent for 60 months, about 4,046 dollars on a 20,000 dollar used-car loan at 7.5 percent, and about 4,620 dollars at 8.5 percent

In this example the used-car loan costs about $10,600 to $11,200 less in total payments, depending on which used-car rate you get. That gap won't always be this large, and it doesn't count repairs or warranty coverage (covered below). But it shows why the CFPB suggests comparing loan amount, APR, term, and monthly payment together, and why the FTC says to know your total cost, not just the monthly payment.

Keep the term the same when you compare

Comparing a 48-month used-car loan with a 72-month new-car loan makes the new car look cheaper per month while hiding thousands in extra interest. Put both on the same term first. Our auto loan term length guide shows how much a longer term adds.

New-car financing perks (and their fine print)

Comparison of new-car financing perks and their catches: 0 percent APR offers, manufacturer cash rebates, and the 2025 to 2028 car loan interest deduction, each with conditions

New cars often come with financing deals you won't find on most used cars:

0% or low-rate offers. The CFPB says dealers and manufacturers may offer incentives such as 0% APR loans and manufacturer cash rebates when they have large inventories. These deals are generally for consumers with the highest credit scores and often require repaying quickly, such as within 36 months. The FTC adds that manufacturer-sponsored programs may be limited to certain cars or require a larger down payment or shorter contract, and that these discounted rates generally aren't negotiable.
Rebates and cash back. The FTC says dealers must clearly explain what's required to qualify, and warns not to assume any rebate is already included in your price.
A federal tax deduction for some new-car loans. According to the IRS, for 2025 through 2028 you may be able to deduct interest on a loan used to buy a qualified vehicle for personal use, up to $10,000 a year, with a phase-out at higher incomes. The vehicle's original use must start with you, so used vehicles don't qualify, and it must have final assembly in the United States. Lease payments don't qualify, and you must report the VIN on your return.

The trade-off: value drops fast

The FTC notes that cars quickly lose value once you drive off the lot, so longer financing can leave you owing more than the car is worth. That risk is usually highest with a new car bought with little money down. A bigger down payment or a shorter term reduces it.

Extra checks when the car is used

Checklist before financing a used car: read the FTC Buyers Guide, check whether it is sold as is, get a vehicle history report, pay for an independent inspection, check for open safety recalls, and get the return policy in writing

A used-car loan is only as good as the car it pays for. Before you sign, the FTC's used-car guide points to these protections and checks:

The Buyers Guide. Dealers must display a Buyers Guide on every used car they offer for sale and give it to you after the sale. It tells you whether the car is sold "as is" or with a warranty and what share of repair costs the dealer will pay. If you negotiate warranty changes, the Buyers Guide must show them, and it overrides contrary terms in the sales contract.
"As is" means no dealer warranty. You take on the risk of anything that goes wrong after the sale. If a car isn't sold "as is," the FTC says implied warranties still cover it even without a written warranty, and how long they last varies by state.
A vehicle history report. The FTC says it may list accidents and flood damage, but typically not mechanical problems. The U.S. Department of Justice's NMVTIS site explains how its title-history reports help protect buyers from title fraud and unsafe vehicles.
An independent inspection. The FTC calls this always a good idea, even if the car is "certified" and inspected by the dealer. A written estimate can help you negotiate the price.
Safety recalls. The Buyers Guide points buyers to FTC information on how to check a car for open safety recalls before buying.
Remaining factory warranty. The CFPB notes a manufacturer's warranty may still cover a used car if its time or mileage limits haven't been reached.
No federal cooling-off period. The FTC says federal law doesn't require dealers to give you three days to cancel; some states do. Get any return policy in writing.

If a used car turns out to have serious problems, the CFPB explains that state lemon laws generally cover used cars only if they're still under warranty or the defect couldn't be fixed after a reasonable number of repairs.

Watch the add-ons on either loan

Whether the car is new or used, the FTC warns that add-ons such as GAP, VIN etching, and rustproofing can cost thousands and sometimes get slipped into deals without discussion. Ask for the price of each one in writing, and remember that financed add-ons raise your payment and interest.

How to choose between new and used

Five steps to compare a new and a used car loan: price both cars out the door, get preapproved rates for each, compare total cost over the same term, add ownership costs and repair risk, then choose the lower total

Get written out-the-door prices for a new car and a comparable used one, as the FTC recommends.
Get preapproved for both a new and a used loan, ideally from a credit union and a bank, so you see real rates. Our guide to how auto loans work covers APR and the Truth in Lending disclosure, and our preapproval vs dealer financing guide shows how to compare a preapproval with the dealer's offer.
Compare total of payments on the same term.
Add ownership costs: insurance quotes for each car, expected repairs, and any warranty gap on the used car.
Choose the lower total cost you can comfortably afford, not the lower payment.

Whichever you choose, a down payment helps. The FTC suggests saving for one first, because it reduces the amount you finance and lowers your total financing costs. On an older used car, a shorter term also helps the loan shrink faster than the car's value, which keeps you closer to owning it outright if something goes wrong.

A new car can make sense if you qualify for a strong promotional rate, plan to keep the car for many years, and value full warranty coverage. A used car often wins on total cost if you're careful about condition and keep the loan short.

FAQ

Are used car loan rates higher than new car loan rates?

Often, but only by a little on average. NCUA data for December 26, 2025 showed 48-month used-car rates of 5.53% at credit unions and 7.73% at banks, versus 5.32% and 7.33% for new cars. Your credit matters more.

Is it cheaper to finance a new or a used car?

It depends on total cost. A used car usually needs a smaller loan, so it can cost less overall even at a higher rate. Compare total of payments on the same term.

Can I get 0% financing on a used car?

It's uncommon. The CFPB describes 0% offers as manufacturer and dealer incentives, generally for buyers with the highest credit scores and often with short terms such as 36 months.

Can I deduct interest on a used car loan?

No. The IRS says the 2025 to 2028 car loan interest deduction applies only to vehicles whose original use starts with you, with final assembly in the United States. Used vehicles and leases don't qualify.

What should I check before financing a used car?

Read the Buyers Guide, get a vehicle history report, pay for an independent inspection, check recalls, and get the return policy in writing, as the FTC recommends.

Can I return a used car after I buy it?

Federal law doesn't require a three-day cancellation period, the FTC says. Some states require one and some dealers offer one, so get the policy in writing before you buy.

Does a certified pre-owned car still need an inspection?

The FTC says an independent mechanical inspection is a good idea even if the car has been "certified" and inspected by the dealer and comes with a warranty or service contract.
