Will a credit card issuer cancel an account if it never incurs interest?
While technically true, a card issuer can cancel your card for almost any reason they want, it's highly unlikely they'll cancel it because you pay your bills! There are many, many people out there that pay their bills in full every month without ever paying a cent in credit card interest. I wouldn't ever purposefully incur any interest on a credit card. Related anecdote: I used to have a credit card that I only used for gas purchases because they gave 5% off for fuel. The issuer eventually discontinued the program (I assume because people like me took advantage of it.) So while they didn't cancel my card, the bonus eventually went away. I miss that card. My conclusion: if you can take advantage of promotional rates, by all means, go for it. You don't owe them any favors. Enjoy it as long as it lasts.
