One of the keys to maintaining a high credit score is to utilize your credit regularly. You have to use it, but then pay it off quickly. You do want to keep your overall debt low. The ratio of your debt to your available credit is one factor in your credit score. However, having zero debt doesn’t necessarily mean that you’ll have a good credit score.
Consider this: if you’ve never had any debt before then you don’t have a credit history at all. Therefore, you can’t have good credit. This is what teenagers face when they first try to get loans. So, although more than one-quarter of people surveyed assumed that having no debt means you’ll have a good credit score, that’s not necessarily true. It may be true, but it may not be. There are other factors to consider.
