Yes, you can use a personal loan to buy a car, and no federal law stops you. Because the loan is unsecured, the lender deposits the money into your bank account and you shop as a cash buyer, free to purchase from a dealership, a private seller, or an owner whose vehicle is too old for a traditional auto lender. The trade-off is a higher interest rate and no eligibility for the new federal car-loan interest deduction. Whether that trade-off is worth it depends on the car you’re buying and the rate you can qualify for.
How It Compares to an Auto Loan
The defining difference is collateral. An auto loan is secured by the car itself, so a lender who isn’t paid can repossess the vehicle without going to court. A personal loan is unsecured. If you default, the lender’s only route to your money is a lawsuit and a court judgment, not a tow truck.
That extra risk shows up in the rate. As of early 2026, unsecured personal loans carry an average APR around 12 percent, with a typical range of roughly 8 to 36 percent depending on your credit. New-vehicle auto loans average around 6.5 percent, and used-vehicle auto loans average roughly 11 percent. Strong credit narrows the gap, but for the same borrower a personal loan almost always costs more in interest than a secured auto loan.
What you get for the higher rate is flexibility. Auto lenders often refuse to finance cars older than ten years or with more than 100,000 miles. A personal-loan lender never looks at the car at all, so age, mileage, and seller type are your business. The title also comes to you clean, with no lienholder listed, meaning you can sell or trade the car whenever you want without asking a lender for a lien release.
When a Personal Loan Makes Sense
A personal loan is worth considering when the car or the sale falls outside what auto lenders will touch:
- The vehicle is too old or has too many miles for an auto lender’s collateral rules.
- You’re buying from a private party and the auto lenders you’ve contacted only finance dealership purchases.
- You want the title in your name from day one, with no lienholder to deal with if you decide to sell.
- You want to eliminate repossession risk. Default still carries serious consequences, but losing the car isn’t one of them.
If you qualify for a competitive auto loan rate on a newer vehicle, a personal loan is usually the more expensive path, and the tax rules below make that gap wider.
The Car Loan Interest Deduction Does Not Apply
Starting with loans originated after December 31, 2024, a federal tax provision allows a deduction of up to $10,000 per year for interest paid on qualifying vehicle loans used to buy new, American-made passenger vehicles for personal use.1Internal Revenue Service. One, Big, Beautiful Bill Act – Tax Deductions for Working Americans and Seniors The deduction requires the loan to be secured by a lien on the vehicle.2Federal Register. Car Loan Interest Deduction
A personal loan is unsecured. No lien is placed on the car, so the interest doesn’t qualify, even if the vehicle itself would otherwise meet the eligibility rules. On a $25,000 loan at 12 percent, you could pay more than $2,500 in interest in the first year alone, none of it deductible. The same buyer using a secured auto loan on a qualifying vehicle could deduct that interest. If the car you’re buying is a new American-made model that would qualify, run the numbers on both paths before deciding a clean title is worth the difference.
Check the Loan Agreement for Use Restrictions
Most personal loans are general-purpose credit, but some contracts include a use-of-proceeds clause listing what the money can and can’t be used for. Common exclusions cover gambling, business investments on a consumer loan, and real estate down payments. Buying a car is almost always permitted, but confirming it in the promissory note before you sign is worth the five minutes.
If you misrepresent how you’ll use the funds, the lender can declare a default and accelerate the debt, making the entire balance due at once. From there, collection runs through the courts.
Applying for the Loan
Federal rules under the USA PATRIOT Act require lenders to verify your identity before opening any loan account. At a minimum you’ll need a government-issued photo ID and a taxpayer identification number, which for most people is a Social Security number.3Financial Crimes Enforcement Network. Interagency Interpretive Guidance on Customer Identification Program Requirements Under Section 326 of the USA PATRIOT Act Before you start the application, gather:
- Recent pay stubs if you’re employed, or two years of federal tax returns if you’re self-employed.
- Your employer’s name, address, and phone number.
- Your monthly rent or mortgage payment.
- Addresses for the past two years.
Lenders use this to calculate your debt-to-income ratio, the share of your gross monthly income that goes to debt payments. A ratio below about 36 percent is a common benchmark, though each lender sets its own threshold.
Many lenders offer pre-qualification through a soft credit inquiry, which doesn’t affect your score. Comparing pre-qualified offers from several lenders before filing a formal application keeps unnecessary hard inquiries off your credit report. A full application triggers a hard pull, which can lower your score by a few points.
Ask for enough to cover the full purchase price plus sales tax, title transfer, and registration, not just the sticker. Under-borrowing can stall the sale at the counter; over-borrowing means paying interest on money you didn’t need.
Underwriting and Funding
After you submit, underwriting can take a few minutes on an automated review or several business days if a person looks at your file. The lender pulls your credit report for items like recent bankruptcies, late payments, or judgments, and verifies the income and employment you listed.
Once approved, you’ll get a loan agreement. Federal law requires the lender to disclose the APR, the total finance charge, and the number, amount, and timing of your payments before you sign.4Office of the Law Revision Counsel. 15 USC 1638 – Transactions Other Than Under an Open End Credit Plan The APR is the best single number for comparing offers because it folds in both the interest rate and certain fees. Once you sign, funds usually reach your bank account by ACH within one to three business days, sometimes the same day.
Watch for Origination Fees
Some lenders charge an origination fee of 1 to 10 percent of the loan amount, often deducted from the proceeds before they hit your account. Borrow $20,000 at a 5 percent origination fee and you receive $19,000. To net the full $20,000, you’d have to borrow roughly $21,050. A loan with a lower rate but a heavy origination fee can cost more than a slightly higher-rate loan with no fee, so weigh both when comparing offers.
Buying the Car and Titling It
With the money in your account, you can pay the seller by personal check, cashier’s check, or electronic transfer. In a private sale, the seller signs the title over to you at the time of payment. You then go to your state’s motor vehicle agency to apply for a new title and registration.
Because the loan is unsecured, no lienholder appears on the title. The agency issues it directly to you, giving you full legal control of the vehicle from day one.
Budget for the costs beyond the sale price. Sales tax varies by state, from zero in a handful of states up to as high as 8.25 percent, and it’s based on where you register the vehicle, not where you bought it. Registration fees range from around $20 to more than $700 depending on state and factors like vehicle weight, age, or value. Title transfer fees typically run $15 to $75.
Insurance
Every state except New Hampshire requires some form of auto insurance to register and drive a vehicle. Because a personal loan is unsecured, no lender is going to require full collision and comprehensive coverage the way an auto lender would. You’re only legally obligated to meet your state’s minimum liability requirements.
Carrying only the minimum is a gamble, though. Total the car and you lose the asset while still owing the full loan balance. Collision and comprehensive coverage protects the car’s value and, by extension, your ability to keep paying the loan without paying for a vehicle you can no longer drive.
If You Fall Behind on Payments
Default on a personal loan doesn’t put the car at risk of repossession, but the fallout is still serious. Most lenders report the account as delinquent to the credit bureaus after 30 days, which damages your credit. After 90 to 180 days of missed payments, the lender may charge off the debt and either keep collecting or sell the account to a collection agency.
If the lender or a collector sues and wins a judgment, that judgment opens the door to wage garnishment, bank account levies, or liens on other property. Federal law caps wage garnishment for consumer debt at 25 percent of your disposable earnings, or the amount by which your weekly earnings exceed 30 times the federal minimum wage, whichever is less.5Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Some states set lower limits.
If you see trouble coming, call the lender before you miss a payment. Hardship programs, deferments, and modified payment plans are often available, and asking early gives you the most options.
