Auto Refinance vs Personal Loan: Which Should You Use to Pay Off Your Car?

It is technically possible to pay off a car loan using an unsecured personal loan instead of a dedicated auto refinance loan, but the two options work very differently, and the difference matters more than most people expect.

An auto refinance loan is a secured loan, meaning the car itself is collateral. This is precisely why auto refinance APRs are typically lower than personal loan APRs for a comparable credit profile, since the lender has the vehicle to repossess if payments stop.

A personal loan used to pay off a car is unsecured, meaning no collateral backs it. This usually means a higher interest rate than a dedicated auto refinance loan would offer, but it also means the car is no longer tied to that specific debt, so missing a payment does not put the vehicle itself at direct repossession risk from that loan.

For most borrowers with a straightforward refinancing goal, a dedicated auto refinance loan is the cheaper option, since the lower APR from the secured structure usually outweighs the flexibility of an unsecured personal loan.

A personal loan can make more sense in a narrower set of cases, such as when the vehicle does not qualify for auto refinancing, for example if it is too old or has too many miles for a lender to accept, or when a borrower specifically wants to avoid any risk of repossession tied to that debt even at a higher rate.

Before choosing either path, get a rate quote for both. The gap between secured and unsecured rates varies by lender and credit profile, and in some cases a strong personal loan offer can come close enough to a refinance rate that the added flexibility becomes worth the small rate difference.
