Credit card debt tends to be more damaging to credit scores than a personal loan, which is considered installment debt. The credit utilization ratio (see previous section) does not take installment debt into account. This strategy would result in zero dollars of credit card debt on the borrower’s credit report, which could boost their score by 100 points or more, says Ulzheimer.
This is easier said than done, but reducing the amount that you owe is going to be a far more satisfying achievement than improving your credit score. The first thing you need to do is stop using your credit cards. Use your credit report to make a list of all of your accounts and then go online or check recent statements to determine how much you owe on each account and what interest rate they are charging you. Come up with a payment plan that puts most of your available budget for debt payments towards the highest interest cards first, while maintaining minimum payments on your other accounts.
