How to Refinance and Remove a Cosigner
If you bought your car with a cosigner or a higher interest rate because of your credit, refinancing later can improve both — once you meet a few key conditions.
How Refinancing Works
Refinancing an auto loan means replacing your current loan with a new one, ideally with better terms — a lower interest rate, a cosigner removed, or both. You apply with a new lender (or sometimes your existing one), who pays off your original loan and issues a new one in its place, now based on your current credit profile rather than the one you had when you first bought the car.
The Key Constraint Most People Don't Expect
A lender generally won't refinance a loan where the vehicle's current value is less than what you still owe. Cars depreciate quickly, especially in the first couple of years, so it's worth checking your vehicle's current market value against your loan payoff amount before you apply. If you owe more than the car is worth, you may need to wait, pay down more of the balance first, or bring cash to the refinance to cover the difference.
When to Apply
Most lenders want to see several months of on-time payments on your current loan before considering a refinance — this establishes a track record and reduces their risk. Combining that payment history with an improved credit score gives you the best shot at both removing a cosigner and securing a lower rate.
Improving Your Odds Before You Apply
The same factors that improve any credit application apply here: paying down other revolving debt, correcting any errors on your credit report, and maintaining a consistent on-time payment history. See our Improve Your Credit Score guide for the specific steps that move the needle fastest.

If credit card or other unsecured debt is what's keeping your score or DTI from qualifying for a better rate, it's worth exploring your options.
