Credit Card Churning: How It Works and the Real Risks

Credit card churning means opening cards mainly for the welcome bonus, then closing or downgrading them and repeating. It runs from one card a year to a dozen or more. The pull is real, because a single bonus can be worth more than a year of everyday earning. The costs are also real, and the banks have been tightening the rules. For most people, one or two well-chosen cards a year does better than churning.

Every strategy here assumes every card is paid in full each month. Welcome offers vary by applicant and change often, and approvals are the issuer's decision.

What churning actually is

	Occasional	Moderate	Heavy
New cards per year	1	3 to 4	Many
After year one	Keeps the card	Keeps or downgrades	Closes or downgrades most
How minimums are met	Normal spending	Normal spending, timed	Often manufactured spending
Tracking load	Light	Moderate	Heavy

Why the math is so tempting

$5,000 of spending over 3 months	Rewards earned	Return on that spend
Flat 2% card	$100	2%
Sapphire Preferred bonus only (75,000 points at 1.8 cents)	$1,350	27%

Spending-based rewards and bonuses have generally been treated as rebates, not income, while referral and no-spend bonuses can be taxable. This is not tax advice.

How the banks push back

Issuer	Main rule	What it means for churning
Chase	5/24 (unpublished, widely documented). Sapphire Preferred and Reserve bonuses are once per lifetime each (since January 22, 2026). An eligibility message appears first	Apply to Chase first. One bonus per Sapphire card, ever
American Express	"Have or have had this Card" language. Family rules (Green, Gold, Platinum). A message before you submit. Clawback terms for abuse, misuse, or gaming, including closing or downgrading within 12 months	One bonus per card. Order matters. Keep every new Amex card at least 12 months
Citi	Strata cards moved from 48 months to "currently have or previously had" language (September 2026). AAdvantage cards still showed 48-month language	Repeat bonuses on Strata cards now appear to be off the table

See the Chase 5/24 rule for how the count works.

The real risks

Risk	What it costs	How to limit it
Credit score	Inquiries (usually under 5 points each) and a lower average account age	Space applications out, and stop before any mortgage or auto loan
Minimum spend	Purchases you did not need, and interest if you carry a balance	Only chase bonuses your normal spending covers, and pay in full
Clawbacks	A lost bonus, and possible closure of other accounts (Amex terms)	Keep new cards 12 months or more, and never return purchases used to hit the minimum
Annual fees	The fee paid in year one	Compare the bonus value with the fee before applying
Time	Missed deadlines and forfeited points	Track every date in one place

For the tracking side, see how to track bonuses, credits, and fees.

Mistakes to avoid

Applying for a card only for the bonus, with no plan to keep it for a year.
Stretching spending to reach a minimum.
Applying for a mortgage or auto loan soon after a run of applications.
Closing a card within 12 months of opening it, at issuers with clawback terms.

So does it work?

Run the five-question check before chasing any bonus:

I pay every card in full, every month.
No mortgage, auto loan, or other major loan is planned in the next 12 months.
My normal spending covers the minimum without stretching.
I have confirmed eligibility under the issuer's rules (5/24, once-per-lifetime, family rules).
I will keep the card at least 12 months and track every date.

If any answer is no, the bonus is probably not worth it. If every answer is yes, how to maximize bonuses without churning lays out a slower approach. The free rewards calculator shows what your everyday spending already earns, which is the baseline a bonus has to beat.
