The big reason why individuals don’t have high credit fico scores is because they simply don’t have the revolving debt or their credit debt is over extended. Simply put, if you’re not making a monthly payment towards credit debt, then the credit bureaus don’t have anything to credit your score with, and being over extended can hurt your score drastically. So try to use your revolving credit cards as much as possible and reduce your credit debt to at least 30% of the credit limit.
