Will a credit card issuer cancel an account if it never incurs interest?
Credit card companies are businesses. Businesses will make any decision that makes them money. So does it make them money to cancel your account? It's a simple cost-benefit analysis: you having an account with them will probably give them some benefit for very little cost to them. The only real cost associated with an open account is someone who uses the card but doesn't pay, but they're pretty sure you won't be doing that.
