I have enough to pay off my auto loan but I want to build my credit. It is a 60 month auto loan and I am about to pass the 12month mark. I can either pay it off now, or pay a little extra interest and keep paying it off over 48 more months. The interest is not really a concern to me. If I want to build my credit is it ok to pay it off now after 12 months or should I just pay it off over 4 more years? Does it matter after a certain amount of months?
