Yes, you can use a personal loan to buy a car. There is no federal law against it, and most personal loan agreements allow vehicle purchases. The real question is whether you should: personal loans almost always carry higher interest rates than auto loans, come with origination fees auto loans rarely charge, and do not qualify for the new federal car loan interest deduction. For some buyers, those costs are worth it. For most, they are not.
When a Personal Loan Actually Makes Sense
Auto loans are cheaper, but they do not fit every purchase. A personal loan tends to win in a handful of specific situations.
- Private-party sales. Many auto lenders will not finance a car bought from a private seller, and the ones that do often charge higher rates than they would for a dealership purchase. A personal loan drops cash in your checking account, and you pay the seller the same way you would with your own savings.
- Older or high-mileage cars. Auto lenders routinely refuse vehicles older than ten years or with more than 100,000 miles on the odometer. Personal loans have no vehicle age or mileage limits because the car is not collateral.
- You want a clean title. A personal loan is unsecured, so no lender places a lien on the car. You appear on the title as the sole owner from day one, free to sell, trade, or modify the vehicle without asking a lienholder for permission.
- Insurance flexibility. Auto lenders require collision and comprehensive coverage for the life of the loan. With a personal loan, you only need to meet your state’s minimum liability requirements.
If none of those apply to you and you are buying a reasonably recent car from a dealership, a traditional auto loan is almost certainly the better financial move.
What It Costs Compared to an Auto Loan
Lenders charge more for unsecured debt because they cannot take anything back if you stop paying. As of early 2026, personal loan APRs for borrowers with excellent credit start around 6% to 8% and climb past 35% for borrowers with poor credit. The average across all credit tiers lands near 12% to 18% depending on the lender.
Auto loans sit noticeably lower. A borrower with excellent credit can expect used-car rates in the 5.5% to 9.5% range; borrowers with fair credit typically see 10% to 15%. On a $20,000 loan over five years, even a 3-percentage-point difference adds roughly $1,600 to $1,700 in extra interest. That gap grows with larger loan amounts and longer terms.
Then there are origination fees, which auto loans rarely charge. Personal loan origination fees typically run 1% to 10% of the loan amount, either deducted from your disbursement or added to the balance. On a $25,000 loan with a 5% fee, you walk away with $23,750 but owe interest on the full $25,000. Some lenders waive the fee entirely, so comparing offers matters here more than it does with most loan types.
Loan amounts generally run from $1,000 up to $50,000, with a smaller group of lenders going to $100,000. If you need more than $50,000, your options narrow and you will need strong credit and income. Repayment terms usually fall between two and seven years. Watch for prepayment penalties in the fine print, because some personal loan lenders charge them and that can wipe out the savings from paying ahead.
The New Car Loan Tax Deduction Does Not Apply
The One, Big, Beautiful Bill Act, signed on July 4, 2025, created a federal deduction for car loan interest of up to $10,000 per year for tax years 2025 through 2028. The deduction phases out for individuals with modified adjusted gross income above $100,000, or $200,000 for joint filers.1Internal Revenue Service.

To qualify, the loan must be secured by a lien on the vehicle, the car must be new rather than used, and final assembly must have occurred in the United States. A personal loan places no lien on the car, so it is disqualified by the first requirement alone, even if every dollar goes toward a brand-new American-assembled vehicle. If you are buying a qualifying new car and your income is under the threshold, that lost deduction is a concrete dollar reason to choose a traditional auto loan.1Internal Revenue Service.

What Happens If You Stop Paying
This is where the unsecured structure of a personal loan cuts in your favor. The lender cannot repossess your car, because the car was never pledged as collateral. Even if you default completely, no one is coming to tow the vehicle. That is a real protection compared to an auto loan, where missed payments can trigger repossession without a court order in most states.
No repossession does not mean no consequences. The lender can send the debt to collections, report the delinquency to the credit bureaus, and sue you. If it wins a judgment, it can pursue wage garnishment. Federal law caps garnishment for ordinary consumer debts at the lesser of 25% of your disposable earnings or the amount by which your weekly disposable earnings exceed 30 times the federal minimum wage of $7.25 per hour, which works out to $217.50 per week.2Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Some states set lower limits, and a few prohibit wage garnishment for consumer debt entirely.
Defaulting on a personal loan used for a car is less immediately disruptive than defaulting on an auto loan, but it still creates serious long-term damage. The lender just has to work harder to collect.
Title, Registration, and Insurance
Because no lender holds a security interest in the car, the title process is simple. After the purchase, you submit the signed title from the seller and a bill of sale to your state motor vehicle agency, pay sales tax and registration fees, and receive a title listing you as the sole owner with no lienholder. Sales tax rates vary widely by state, from zero in a handful of states to over 10% in jurisdictions with high local add-ons.
With no lender dictating your coverage, you only need the liability insurance your state requires. Auto lenders force you to carry collision and comprehensive coverage, which can add hundreds of dollars a year to your premium. Whether dropping that coverage is wise depends on the car. On an inexpensive used vehicle, the savings may be worth it. On a newer car, you are gambling with your own money rather than the lender’s.
What Lenders Prohibit, and What They Don’t
Most personal loan agreements allow broad spending. The common prohibited uses are gambling, illegal activity, college tuition, business expenses with some lenders, and home down payments. Buying a car almost never appears on the restricted list. Still, read your specific agreement before signing. If you use the funds for a prohibited purpose, the lender can call the full balance due immediately.
How to Shop the Loan
Most lenders let you check an estimated rate through prequalification, which uses a soft credit pull and does not affect your score. Run prequalification with at least three or four lenders before you apply formally, since the comparison costs you nothing. When you submit the real application, the hard inquiry typically drops your score by fewer than five points.
Online lenders can fund the same business day; banks and credit unions more commonly take one to five business days. The money lands in your checking account, and you pay the seller by cashier’s check, wire, or in some cases a personal check.
Three things to confirm before you sign: the APR after any origination fee is included, whether the lender charges a prepayment penalty, and that the agreement does not restrict vehicle purchases. The extra interest you pay compared to an auto loan is the price of the flexibility a personal loan gives you. Make sure that flexibility is actually solving a problem you have.
