Sign-Up Bonuses: How Minimum Spend Works, and When It Costs More Than It Pays
The bonus is real money and the condition attached to it is a deadline. It only works if the spending was going to happen anyway — which is exactly the assumption the offer is built on, and the one worth checking before you apply.
Key takeaways
- A welcome bonus requires a minimum spend inside a fixed window, commonly three months from account opening.
- The clock starts at account opening, not at card activation or first use.
- Only purchases count. Balance transfers, cash advances and fees generally do not.
- Manufactured spending to hit the target usually costs more in fees than the bonus is worth, and can get the account closed.
The short answer
Issuers pay a bonus because a new cardholder is worth more than the bonus over time. The offer is genuine, the value is real, and the terms are precise.
It is worth taking when the required spending was already in your budget. It stops being worth taking the moment you start buying things to reach the target — the bonus is a fraction of the spend, so spending an extra dollar to earn twenty cents is a bad trade dressed as a good one.
The terms that decide whether you get it
Every one of these is in the offer text, and each has caught people out.
| Term | The detail that matters |
|---|---|
| The window | Usually three months, and it runs from account opening — not from when the card arrives or is activated |
| What counts as spending | Purchases only. Balance transfers, cash advances, fees and often gift-card-like transactions are excluded |
| When the bonus posts | Typically one to two billing cycles after you qualify, not immediately |
| Eligibility rules | Many issuers exclude anyone who has held the same card recently, or restrict how many new accounts you may open in a period |
| Whether returns count against you | Yes. A refund reduces your qualifying spend and can pull you back under the threshold |
| The annual fee | If the fee is charged in year one, subtract it from the bonus before calling it free money |
The arithmetic that decides whether it is worth it
Take the bonus, subtract any first-year annual fee, and compare it against what you would have earned on the card you were already using. That difference is the actual gain.
Then check the spend requirement against your ordinary budget over the window. If the target is below what you would spend anyway, the gain is real. If it is above, the excess spending is a cost that has to come out of the same sum.
A useful sanity check: a bonus is generally somewhere between 5% and 15% of the required spend. Spending $1,000 you did not need to spend, to earn $150, leaves you $850 poorer.
Hitting the target without wasting money
Legitimate ways to move existing spending onto the new card, none of which involve buying anything extra.
- Time the application ahead of spending you already have coming: an annual insurance premium, a booked trip, a planned appliance replacement.
- Move your recurring bills onto the card for the window, then move them back if you prefer.
- Pay the balance in full each cycle regardless. Interest at a card APR eats a bonus in a few months.
- Do not pay a bill by card if the biller charges a convenience fee — a 2.5% fee to earn a 1.5% reward is a loss, even when it helps you hit a threshold.
Where this goes wrong
Manufactured spending — buying cash equivalents to inflate the total — is the well-known failure mode. It generally loses money once the fees are counted, most issuers exclude those transactions from qualifying spend anyway, and the accounts get closed with the rewards clawed back.
The quieter failure is applying repeatedly. Each application is a hard inquiry and each new account lowers your average account age, so a run of applications ahead of a mortgage is expensive in a way the bonuses do not cover.
And the quietest one: carrying a balance. A bonus worth a few hundred dollars is wiped out by a few months of interest on a four-figure balance. The bonus assumes you are a transactor; if you are not, the card is costing you.
Frequently asked questions
Are sign-up bonuses taxable?
A bonus earned by meeting a spending requirement is generally treated as a rebate on your own purchases rather than as income. A bonus paid simply for opening an account, with no spending required, can be reported as income on a 1099. Ask a tax professional about your own situation.
When does the spending window start?
At account opening, in almost every offer. If the card takes ten days to arrive, those ten days came out of your window — which is why the effective period is often shorter than the advertised three months.
Can I get the same bonus twice?
Usually not within a defined period, and the rules differ by issuer. Some exclude anyone who has received the bonus on that card in the last two years; others limit how many of their cards you can hold at once.
What if I miss the deadline by a little?
The bonus is forfeited. Issuers apply the threshold literally, and a refund that lands after you qualified can retroactively push you below it. Aim to clear the target with room rather than exactly.

Terms used in this guide
- Welcome bonus
- A one-time reward for spending a set amount within the first months. It is the most volatile figure on a card: issuers change it often, so check it on the issuer's own page before applying.
- Rewards
- What the card gives back on spending: cash back, points, or miles. The headline rate usually applies only to specific categories or up to a cap.
- Annual fee
- What the issuer charges every year just to keep the card open, whether you use it or not. A $0 fee card can still cost you in interest.
- Credit score
- The score range an issuer suggests for approval. It is guidance, not a guarantee: income, existing debt and your history with that bank all weigh in.
