Is it ever a good idea to close credit cards?
It is an issue of both utilization and average age of accounts. If your cards with $0 balances on them are: A) newer cards than the ones you are carrying balances on and you don't want them B) much lower limit cards than the ones you are carrying balances on then you can raise your score by closing them, as the utilization change won't be a large factor and you can raise the average age of your open accounts.
