Bonus caps
Category spend capsLast reviewed
A bonus cap is a hard limit on how much spending earns the elevated rate in a category, or across rotating categories, for a period - often a month or a quarter. Once that spend is used up, further purchases in the same category usually earn the card's base rate, not the headline bonus.
That is why a card that was right for a category in January can be wrong for the same category in March without the issuer changing a printed rate. A cap is not an annual fee, and it is not a welcome-bonus spend milestone.
Once the cap is spent, compare base rates. The printed bonus is no longer the rate you will be paid.
What a cap is, and what it is not
A spend cap means the bonus rate applies only to the first fixed amount of eligible spend in the period. Some cards share one cap across more than one elevated category, so hitting the pool in groceries can exhaust the bonus for dining too.
A cap is not an annual fee: a fee is a fixed cost, a cap is a ceiling on earning at the bonus rate. It is also not a welcome bonus. Signup spend milestones are a different clock.
CardLab does not invent caps. When a rate ships in the catalog, it carries the issuer page, the verbatim sentence, and the date it was read - the same provenance rule as every other claim.
Why the ranking flips mid-period
Ranking cards by headline rate alone answers last month's question. A useful answer needs the earn rate for this category, how much of the bonus cap is still open on your cards, and whether you are clearing the statement balance.
When the remaining cap is smaller than the purchase, the honest answer splits the spend: bonus rate on the part under the cap, base rate on the overflow - or a different card for the overflow entirely. That is the product behavior Best Card is built around.
Illustrative arithmetic, not an issuer quote: suppose Card A pays 3% on groceries up to a quarterly spend cap, then 1% after, and Card B pays a flat 2% with no grocery cap. Once Card A's quarterly bonus is spent, the next $100 of groceries earns $1.00 on Card A and $2.00 on Card B. The ranking flips even though Card A's printed grocery bonus is still 3%.
How to track caps without a bank login
Caps are terms plus your spend against those terms. Terms come from the issuer's product page and your agreement. Spend against the cap is what you logged, or what you accepted from an on-device statement import.
CardLab's tracker is built that way: no bank login, no real card number, data on-device by default. Statement import reads a PDF or screenshot on the phone into a review inbox. Nothing hits balances or caps until you accept the rows.
Common questions
What happens after I hit a credit card bonus category cap?
Eligible spending usually earns the card's base rate until the cap resets, often at the start of the next month or quarter. The elevated rate does not keep paying just because the category name is still printed on the marketing page.
Do all bonus categories have caps?
Many do; some flat-rate cards do not use category caps at all. Always read the issuer's own wording for the period, the amount, and whether categories share a pool.
Should I keep using the same card after the cap?
Only if its post-cap rate still beats your alternatives, or if another reason - purchase protection, no foreign-transaction fee - matters more than earn rate. For pure rewards math, compare the base rate to your next-best card.
How does CardLab handle bonus caps?
Best Card is cap-aware: a card that has spent to its bonus cap stops winning on a rate it can no longer pay, and the answer says so. Ranking is offered in markets with a verified catalog.
Is this financial advice?
No. CardLab is educational. Check the issuer before you rely on a number; rates and caps change.
