Certainly. There’s many cards that provide promotional 0% interest rates for 12 months. The idea is every 12 months you sign up for one of these cards and you can make minimum payments with no interest, when the card is reaching the end of its promotional period you just pay it off in full and don’t use it anymore unless there’s good rewards.

Ah. I hadn't considered credit card churning. Thanks!

(I do have some reservations -- I'm guessing that only a small minority of cardholders attempt to churn their balance from card to card or pay it off before the end of the promotional period. 12-month lines of credit don't come for free, and if the expected average payoff wasn't worth it, credit card companies would probably stop running these promotions.)

It is 100% free money. The catch is you will be charged all the interest in some cases if you reach the end of the promotional period and haven’t paid off the card in full, or something like that.
