This is why you can have a crap credit score, despite having student loans and car loans. Bad management of credit card debt often translates into bad management of other forms of debt.
Note that the <20% balance refers to your overall combined credit limit. If you have 2 cards with a $1000 limit, you could have one card with $400 and the other card with $0 and be OK. Though, avoid going over more than 60% on any one card, regardless.
