How sign-up bonuses actually work
The big bonus on a new card is real money — but only if you understand the spending requirement, the clock, and the small print. Here is the honest version.

You have probably seen the headline: open this card, earn a big pile of points or miles. That reward is called a sign-up bonus, or welcome offer. It is one of the most valuable things in the credit card world — and also one of the easiest to accidentally miss out on. Here is exactly how it works.
The deal in one sentence
The issuer says: spend a certain amount on this card within a certain number of months, and we will give you a reward. That is the whole mechanic. The reward might be points, miles, or a straight statement credit, and the exact size of the bonus, how much you must spend, and how long you have are all set by the issuer.
The minimum spend is the catch
The required spending amount is called the minimum spend, and meeting it is the whole game. Miss it by even a little, and you usually get nothing — not a partial bonus, nothing. So before you apply, ask yourself one honest question: will I naturally spend that much on this card in that window, on things I was going to buy anyway?
If yes, the bonus is essentially free. If you would have to manufacture spending or buy things you do not need just to hit it, the “reward” can quietly cost you more than it gives. A bonus is only a deal if you reach it without distorting your normal spending.
What usually counts — and what does not
Generally, normal purchases count toward the minimum spend. Things that typically do not count include balance transfers, cash advances, fees, and similar non-purchase transactions. The precise list is set by the issuer, so read the offer terms rather than guessing. This is the kind of detail worth confirming before you start counting on a transaction.
When the bonus actually shows up
Here is where people panic for no reason: the bonus rarely appears the moment you hit the spend. Most issuers post it one or two billing cycles later. So if you met the requirement and the reward is not there yet, give it a statement or two before worrying — and the exact timing is, again, set by the issuer and spelled out in the terms.
Two honest cautions
An annual fee can offset the bonus. If the card has a fee, factor it in. A reward is less impressive once you subtract the cost of holding the card. (We have a whole guide on doing that math.)
Applying affects your credit. Opening a new card usually causes a small, temporary dip in your credit score, and some issuers limit how many new accounts they will approve. Chasing bonuses constantly is not free of consequences. One thoughtful application is very different from many rushed ones.
The honest part
We earn no commission from any issuer, so we are not steering you toward any particular card’s offer. The point of this guide is just to make sure that if you do go for a bonus, you do it with eyes open: know the spend, watch the clock, count only what qualifies, and make sure the reward survives after the annual fee. A sign-up bonus is great money when it fits your real life — and a quiet trap when it does not.
