Refinancing your car loan is one of the highest-return financial moves available. The average borrower who refinances saves $1,200 per year. Here are the 10 best lenders to do it with in 2026.

Refinancing isn't always the right move. Here's how to know if the numbers work in your favour.
These scenarios are based on actual rate reductions borrowers achieved by comparing lenders through our platform.
Most refinances take 1–5 business days from application to funding. Online lenders like AUTOPAY and Caribou typically fund within 24–48 hours of approval. The new lender pays off your existing loan and you start making payments on the new loan. LightStream offers same-day funding for qualified applicants who apply by 2:30pm ET on business days.
Slightly and temporarily. A hard inquiry when you formally apply typically reduces your score by 3–5 points. Multiple inquiries within 14 days (FICO) or 45 days (VantageScore) count as one inquiry. Once the new loan is established and you start making payments, your score typically recovers within 3–6 months. The long-term effect of paying less interest and having a lower balance is positive.
Yes — there's no legal limit on how many times you can refinance a car loan. It becomes worthwhile when there's been a meaningful change: a rate drop of 1.5%+, a significant credit score improvement (50+ points), or a need to change your loan term. However, each refinance resets interest front-loading and extends the time you're paying, so make sure the numbers genuinely work each time.
Typically: your current loan account number and lender details, your vehicle's VIN number and current mileage, proof of income (last 2 pay stubs or tax return if self-employed), proof of insurance, and your driver's licence. The new lender handles contacting your existing lender directly in most cases. Caribou specifically manages all the paperwork including any DMV title transfers required.
