“As strange as it may sound, it is usually better for your credit to keep your loan.
While paying off a car loan can be good for your credit if you consistently make payments on time, paying off your loan completely will cause a small drop in your credit score. This is because the loan will no longer be an active item on your credit, and therefore you will have fewer items that you are actively paying at once.
In short, several factors determine your credit score. When you have a car loan and pay it off, your score will usually drop, but there are other cases in which a paid car loan will improve your credit. You’ll need to carefully evaluate your situation (or consult a financial professional) to figure out exactly what will happen to you.
