What an American Express sign-up bonus actually is
An American Express sign-up bonus is a reward the company offers you for opening a new card and spending a certain amount of money within a set timeframe. The bonus usually comes as statement credits, points you can redeem for travel or purchases, or cash back. You do not receive the bonus straightforward for opening the card — you have to meet a spending requirement, often called a minimum spend.
The catch is that these bonuses come with real costs. You may pay an annual fee to hold the card. You may spend more than you normally would just to hit the minimum spend requirement. And if you carry a balance, interest charges can erase the bonus value in weeks. The bonus is only worth pursuing if you were already planning to spend that money anyway.
Key Takeaways
- Sign-up bonuses require you to spend a specific amount within a specific timeframe — usually three to six months — to receive the reward.
- Most American Express cards charge an annual fee, which you pay whether or not you use the card, and this fee reduces the real value of your bonus.
- Carrying a balance on the card will cost you interest that far exceeds any bonus value, so only pursue a sign-up bonus if you can pay the full statement balance each month.
- The bonus is only financially sound if you were already planning to make those purchases — manufactured spending to hit the minimum can cost more than the bonus is worth.
How the spending requirement works
When you open an American Express card, the company specifies a dollar amount you must spend and a window of time in which to spend it. A typical requirement might be $3,000 in purchases within the first three months. Some cards require $5,000 or more; others are lower. The clock starts the day your account opens, not the day you receive the physical card.
Spending counts toward the requirement when the transaction posts to your account, not when you make the purchase. A charge made on day 89 of a 90-day window may not post until day 92, which means it will not count. Check your card's terms for the exact posting timeline. Some cards allow you to count certain categories of spending — like travel or dining — while others count all purchases equally.
If you do not hit the minimum spend within the timeframe, you do not receive the bonus. There is no partial credit. Missing the requirement by $50 means you get nothing. This is why reading the terms before you open the card matters: a $5,000 requirement you cannot meet is a waste of a new account inquiry on your credit report.
Annual fees and whether the bonus covers them
Most American Express cards that offer sign-up bonuses also charge an annual fee. Common fees range from $95 to $550 or more, depending on the card. This fee is charged to your account once per year, usually on your card anniversary. You pay it whether you use the card or not.
A $200 sign-up bonus sounds good until you realize the card costs $95 per year. Your real first-year gain is $105. If you do not use the card after the first year, you are paying $95 annually for nothing. Some cards offer annual credits — for example, a $200 travel credit — that offset the fee if you use them, but you have to actually spend money to claim them. These credits are not automatic.
Before opening any card, subtract the annual fee from the bonus amount. If the result is less than zero, or if it is a small positive number that does not justify the work of managing another account, the card is not worth opening.
The real cost of manufactured spending
If you do not naturally spend enough to hit the minimum requirement, you might consider making purchases you would not otherwise make — buying gift cards, paying bills early, or purchasing items you do not need. This is called manufactured spending, and it almost always costs more than the bonus is worth.
Here is a concrete example: suppose a card offers a $300 bonus for $5,000 in spending, and you normally spend $2,000 per month. You would hit $5,000 in the first three months without trying. But if you normally spend only $1,000 per month, you would need to manufacture $2,000 in extra spending. If you buy gift cards or items you do not need, you are spending real money to earn a bonus. Even if the bonus is $300, you have spent $2,000 to get it — a poor trade.
The only exception is if you can manufacture spending with no out-of-pocket cost — for example, by paying a bill you were going to pay anyway using the new card instead of your old payment method. But most manufactured spending involves real money leaving your account.
Interest charges will erase your bonus
A sign-up bonus only makes financial sense if you pay your full statement balance every month. If you carry a balance, interest charges will quickly exceed the bonus amount. American Express cards typically charge interest rates between 16% and 27% annually, depending on your creditworthiness and the card.
Suppose you spend $5,000 to earn a $300 bonus, but you can only pay $2,000 of it when ready. You carry a $3,000 balance. At 20% annual interest, you will pay roughly $50 in interest the first month alone. By month three, you will have paid more in interest than your bonus was worth. The bonus is gone.
This is the most common way people lose money on sign-up bonuses. They open the card for the reward, hit the spending requirement, and then cannot pay the balance in full. The interest charges dwarf the bonus. Only open a card if you are certain you can pay the entire balance when the statement arrives.
Comparing bonuses across different American Express cards
American Express offers different cards with different bonuses. The Blue Cash Everyday card might offer a smaller bonus with no annual fee. The Gold Card might offer a larger bonus but charge $250 per year. The Platinum Card might offer an even larger bonus but cost $695 annually and require much higher spending.
To compare them fairly, use this formula: (Bonus amount minus annual fee) divided by the spending requirement. This gives you the real value per dollar spent. A card offering $500 bonus minus $95 fee equals $405 real value on a $5,000 requirement. That is 8.1 cents per dollar spent. Another card offering $300 bonus minus $0 fee equals $300 real value on a $3,000 requirement. That is 10 cents per dollar spent. The second card is the better deal, even though the bonus is smaller.
Also consider whether you will actually use the card after the first year. If you will not, the annual fee in year two makes the card a net loss. Some people open cards for bonuses and close them after a year; others keep them open if the card offers ongoing value through rewards or credits.
How sign-up bonuses affect your credit
Opening a new credit card triggers a hard inquiry on your credit report. This is a formal request to check your credit, and it can lower your credit score by a few points. The impact is usually temporary — the inquiry falls off your report after 12 months and stops affecting your score after about six months.
Opening the card also adds a new account to your credit history. This lowers your average account age, which can also lower your score slightly. However, having more available credit can improve your credit utilization ratio — the percentage of your total credit limit that you are using — which helps your score over time.
If you are planning to explore for a mortgage, car loan, or other major loan in the next few months, opening a new card for a bonus is not worth the temporary score hit. Wait until after you close on the loan. If you are not explore for credit soon, the impact is minor and temporary.
Frequently Asked Questions
Do I have to use the card after I get the bonus?
No, but you may want to. If the card has an annual fee and you do not use it, you are paying money for nothing. If the card has no annual fee, you can close it or let it sit unused. Closing it when ready after getting the bonus can look suspicious to credit card companies and may affect your ability to get bonuses from them in the future.
What happens if I close the card before the bonus posts?
You will not receive the bonus. The bonus is typically credited to your account within one to three months after you meet the spending requirement, but some cards take longer. Do not close the card until you see the bonus in your account.
Can I get the same sign-up bonus twice?
American Express has rules about how often you can receive a bonus on the same card. You typically cannot get a bonus on the same card more than once every 24 months, and some cards have longer waiting periods. The company tracks this, so attempting to circumvent the rule will result in denial of the bonus.
Does the bonus count as income for taxes?
The IRS does not currently treat credit card sign-up bonuses as taxable income for most people. However, if you manufacture spending or engage in unusual activity to earn bonuses, the IRS could potentially view it differently. For typical sign-up bonuses earned through normal spending, you do not owe taxes on the bonus amount.
What if I cannot meet the spending requirement?
You will not receive the bonus. There is no partial credit or extension. If you realize partway through the window that you will not hit the requirement, you can still use the card normally, but you will not get the reward. Some people close the card at this point to avoid paying the annual fee in year two.
