What a credit card sign-up bonus is, and what it costs you
A sign-up bonus is a reward a credit card company offers you for opening an account and spending a certain amount of money within a set time frame — usually three to six months. The bonus typically comes as cash back, points, or miles that you can redeem for travel or statement credits. The catch is that you have to spend real money to unlock it, and the card often charges an annual fee.
The math looks straightforward on the surface: spend $3,000 in three months, get $500 back. But that $500 is only worth $500 if you were going to spend that $3,000 anyway. If you're spending money you wouldn't normally spend just to hit the bonus threshold, you're paying interest and fees to chase a reward — which means you're losing money, not gaining it.
The other hidden cost is the annual fee. Many cards with generous bonuses charge $95, $150, or more per year. That fee hits your account whether you use the card or not. If you close the card after the first year, you've paid the fee once. If you keep it open to avoid damaging your credit score, you'll pay it again next year unless you actively cancel.
Key Takeaways
- Sign-up bonuses require you to spend a minimum amount within a specific timeframe, usually three to six months, to receive the reward.
- The bonus is only profitable if you were already planning to spend that money; manufactured spending to hit the threshold costs more than the reward is worth.
- Annual fees on bonus cards often range from $95 to $150 or higher, and they renew each year unless you cancel the card.
- Your credit score temporarily drops when you open a new card, and closing cards can lower your score by reducing available credit.
- The best bonus is one on a card you'll actually use regularly, because ongoing rewards and benefits matter more than a one-time payout.
How the minimum spending requirement works
The card issuer sets a dollar amount you must spend within a window of time — for example, $5,000 in the first three months. This spending usually counts toward the bonus only if you use the card itself; transfers, balance transfers, and cash advances typically don't count. Some cards exclude certain categories like gambling or government fees.
The timeframe is strict. If the requirement is three months from account opening and you hit $4,900 on day 91, you don't get the bonus. Set a phone reminder for the important date, or track your spending in writing. Many people miss bonuses because they lose track of the clock.
If you have a spouse or partner, some cards let you add them as an authorized user without a hard credit pull. Their spending may count toward your minimum, which can make hitting the threshold easier — but confirm this with the card company before you rely on it.
When a bonus makes financial sense
A sign-up bonus is worth pursuing only if you meet the spending requirement with money you were already going to spend. This means looking at your actual spending over the past three months: groceries, gas, utilities, insurance, subscriptions, rent or mortgage payments if the card accepts them. If you genuinely spend $5,000 in three months anyway, a $500 bonus is a real gain.
The bonus also makes sense if you're planning a large, necessary purchase — a car repair, medical procedure, or home improvement — within the timeframe. You're spending the money regardless; the bonus is a side benefit.
A bonus does not make sense if you're carrying a balance on another card at high interest. A $500 bonus is worthless if you're paying $1,200 in interest charges on existing debt. Pay down debt first, then chase bonuses.
Annual fees and whether to keep the card open
After your first year, the annual fee renews automatically unless you call the card company and cancel. Many people forget this step and pay a fee for a card they no longer use. Mark your calendar for one month before the anniversary date and decide: will you use this card enough to justify the fee?
Some card companies offer a retention bonus — a smaller reward for keeping the card open another year — if you call and ask. This is negotiable. If you've spent money on the card and have good payment history, the company may offer you $50 to $100 in statement credit to offset the annual fee. It never hurts to ask, but don't count on it.
If you decide to close the card, do it after the annual fee posts but before the next one renews. Your credit score will drop slightly when you close it because your available credit decreases, but the damage is temporary — usually a few months. Keeping a card open just to avoid a small score dip costs more than the dip itself.
How sign-up bonuses affect your credit score
Opening a new credit card triggers a hard inquiry, which temporarily lowers your score by a few points — usually 5 to 10 points. This dip fades within a few months as long as you pay on time. Multiple hard inquiries in a short period (within 14 to 45 days, depending on the scoring model) may count as a single inquiry, so if you're opening several cards, space them out or do it within a short window.
Your score also drops slightly when the new account first appears because it lowers your average account age. A brand-new account with zero history looks riskier than an old account with a long track record. This effect also fades over time.
The bigger risk is closing the card later. When you close an account, you lose that available credit, which raises your credit utilization ratio — the percentage of your total credit limit that you're using. If you have $10,000 in balances and $50,000 in total available credit, your utilization is 20%. Close a card with a $15,000 limit and your utilization jumps to 25%, which can lower your score. This is why some people keep old cards open even after the annual fee hits.
Comparing bonuses across different card types
Sign-up bonuses vary widely by card category. A basic cash-back card might offer $100 to $200 for spending $500 to $1,000. A premium travel card might offer 50,000 to 100,000 points (worth $500 to $1,000 in travel value) for spending $3,000 to $5,000. A business card might offer even larger bonuses because business owners tend to spend more.
The value of points and miles depends on how you redeem them. A travel card's 50,000 points might be worth $500 if you book through the card's travel portal, but only $250 if you transfer them to an airline partner. Cash back is simpler — $500 cash back is always $500. If you're not sure you'll use points, a cash-back card is the safer choice.
Some cards offer category bonuses instead of sign-up bonuses: extra cash back on groceries, gas, or dining for the first year. These can add up to more than a flat sign-up bonus if you spend heavily in those categories, but they require you to use the card consistently. A sign-up bonus is a one-time payout; category bonuses are ongoing.
Red flags and common traps
Watch out for cards that require you to spend more than you reasonably will. A $10,000 minimum in three months is $3,333 per month — realistic for some households, impossible for others. Be honest about your actual spending before you open the card.
Avoid opening multiple cards at once just to stack bonuses. Each new account lowers your score, and if you miss a payment while juggling multiple new cards, the damage compounds. If you do open multiple cards, space them out by at least a month and make sure you can manage the payments.
Don't confuse a sign-up bonus with a promotional 0% APR offer. Some cards offer both: a bonus for opening the account, plus 0% interest for 12 months on purchases or balance transfers. These are separate benefits. The 0% offer is valuable if you're planning to carry a balance, but remember that after the promotional period ends, interest rates jump to the card's regular APR — often 18% to 25%.
Frequently Asked Questions
Can I get a sign-up bonus if I already have a card from the same company?
Most card companies have rules against stacking bonuses. You typically can't get a bonus if you've held the same card or a similar card from that issuer within the past 24 months. Some issuers are stricter — they may require 48 months or more between bonuses. Check the card's terms before you explore.
What happens if I don't hit the minimum spending requirement?
You straightforward don't receive the bonus. The card company won't penalize you or close your account. You can still use the card normally and earn ongoing rewards. However, you'll still owe the annual fee if the card charges one.
Do I have to use the bonus right away, or can I save it?
This depends on the card. Cash-back bonuses usually post to your account as a statement credit that you can use whenever you want. Points and miles typically sit in your account indefinitely, though some cards have expiration policies — check your card's terms. Travel rewards sometimes expire if your account is closed.
Is it better to get a bonus or to use a card with no annual fee?
If you spend enough to hit the bonus threshold with money you were already planning to spend, the bonus card usually wins. A $500 bonus minus a $95 annual fee is still $405 ahead. But if you won't hit the threshold, a no-fee card with ongoing cash back is better because you earn rewards on every purchase without paying to keep the account open.
Can I transfer my sign-up bonus to someone else?
No. Sign-up bonuses are tied to your account and can't be transferred, gifted, or sold. Only you can redeem the bonus on the card it was issued to.
