What is credit card churning?
Churning is opening credit cards mainly to earn their sign-up bonuses, then moving on to the next. Done carefully it can generate real value; done carelessly it burns your credit access. Here's the honest version.

How it works
A welcome offer pays a large bonus for spending a set amount in the first few months. Churners open a card, meet the spend, collect the bonus, and later downgrade or cancel — then repeat with another card. The appeal is simple: a single welcome bonus can be worth more than a year of everyday earning.
The rules that get in the way
Issuers fight back with rules. The best-known is Chase's 5/24: open five or more cards from any issuer in 24 months and Chase generally won't approve you. Amex pays most welcome bonuses only once per card, per lifetime. Many issuers limit how often you can earn a bonus (for example, one every 24-48 months) or how many of their cards you can hold. Break the pattern they're watching for and you get denied — or clawed back.
The real risks
Each application is usually a hard inquiry and a new account, which can dent your score short-term. Annual fees come due whether or not you used the card. Meeting a spend requirement by buying things you don't need destroys the entire point. And carrying a balance at a rewards card's high APR erases any bonus many times over. Churning only makes sense if you pay in full, every month, without fail.
Is it worth it?
For organized people with steady, plannable spending and zero interest carried, the math can be excellent. For everyone else it's a fast way to hurt your credit and pay fees for bonuses you never cleanly earn. We don't count unearned bonuses in any of our math — a bonus you don't hit is worth exactly zero, which is the same way you should treat it.
