No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Under many circumstances it certainly makes sense. Do you now have a high balance reporting on one of your cards? If the card now has high utilization, you'll definitely get dinged a little even if your overall utilization is good.
On the other side of the equation, if you've now paid off all cards and none of them have even a small balance reporting, you'll also get dinged. It's best to have at least one or two cards reporting a small balance (1%-9%). Ultimately you're better off having everything completely paid, but your FICO score likes to see at least that you use credit responsibly, and in their terms, that means carrying a small balance, not having everything paid in full. Crazy game indeed....
