"wyshadow"Having credit can be either good or bad. For example: Lets say you have $1000 line of credit. Depending on when your credit score is checked as it relates to how much money you put on credit can either hurt you or help you. Having $100 or $900 consistently every month is actually bad for you, and so is having a zero balance owed every month meaning you pay off your credit card every month. How can that be? Well, the $100 balance tells the bank they won't make much money off you. The $900 balance tells the bank you are might be in trouble even though they are making a killing from you. In either case, the $100 and the $900 equals a low credit score. Another credit score factor is your past history on payment and late fees. The best way for good credit (in my opinion) is to play it right in the middle (try not to put more 70% of your line of credit) and to always try to pay double your monthly fee and to never have a late charge. If you can show the bank you have a good history of putting $600 on a $1000 line of credit, and it takes you a few months to pay it off, you will have a great credit score and bank could increase your line of credit. But if it takes you several years to pay off a $900 with numerous late fees, this will equal a very low credit score and the bank could lower your line of credit. To what every has said, its all about self control and being smart with your money.
