Will a credit card issuer cancel an account if it never incurs interest?
Remember, the card company gets a percentage at the time of purchase, as well as any interest you let them collect from you. Yes, they're still making a profit on our accounts, and they can always hope that at some point we'll run up a high enough bill to be willing to pay some interest. They may kill completely inactive cards, since they need a bit of income to pay for processing the account. But if you're actively using it, they aren't very likely to tell you to go away (though they may change which plan(s) they offer you).
