The answer to the question is yes it can, but it doesn’t always lower your scores. The reason it can lower your scores is because you lose the available credit in the calculation of what’s referred to as “revolving utilization.” This is the relationship, expressed as a percentage, of your aggregate credit card balances as compared to your aggregate credit card credit limits. You want this percentage to be as low as it can be. Closing cards will result in a lower aggregate credit card credit limit figure, thus making it possible that your utilization percentage will increase and cause your score to decrease.
