It only hurts your FICO score if it is closed by the credit company. If you cancel the account, be sure it shows as 'cancelled by cardmember' or something like that on your credit report. I did this for all the store cards that I had for the promotional financing, ie. Circuit City for my computer. Also closed a Sears account, Express, Victoria's Secret because I only opened those when I was 18 to establish credit. Well, 10 years later and 2 paid in full car loans made those unneccessary...plus I never used them except for the first year. Anyways, your FICO score is determined by complex mathematics, but I know they look at your annual income, account status, and how much credit is available to you. So if you have 5 cards each with 3,000 limits, you have the potential to go into debt for 15,000. In the simplest way, it's your debt to income ratio and they are considering the possibility of how much debt you could potentially accrue. So it's a good idea to cancel the cards you don't use so that your FICO score could improve. I would keep the oldest accounts since that establishes a longer history of regular payments. Ok, credit 101 class dismissed
