Credit card sign-up bonuses can be worth hundreds of dollars in cash back, points, or miles. To earn one, you usually have to spend a set amount on the new card within the first few months, known as the minimum spend requirement. Hitting that target is easy if it matches what you already spend and risky if it pushes you into purchases you do not need or debt you cannot clear. This guide covers how minimum spend works, what counts towards it, and how to meet it without paying for the bonus in interest or stress.
How sign-up bonuses work
A typical offer reads something like “earn 60,000 points after you spend $4,000 on purchases in the first 3 months.” Three parts matter:
- The bonus, in cash, points, or miles.
- The minimum spend, the total of qualifying purchases you must make.
- The window, usually counted from account opening, not from when the card arrives in the post.
The bonus normally posts after the statement in which you cross the threshold, or within a few weeks of it. Keep the card open and in good standing until it does, and usually well beyond that.
Start with the budget, not the bonus
The safest rule is simple: only apply for a card whose minimum spend you can reach with purchases you were going to make anyway. Add up your regular monthly spending that can go on a card, such as groceries, fuel, utilities, phone bills, insurance, and subscriptions, and multiply by the length of the window. If the result is comfortably above the requirement, the offer suits you. If it falls short, the gap is the amount you would have to spend unnecessarily, which quickly cancels out the value of the bonus.
A useful moment to open a new card is ahead of a large expense you already have planned, such as a tuition payment, a home repair, or annual insurance premiums, provided the merchant accepts cards without a surcharge.
Always pay in full
Credit card interest rates are high, commonly above 20% APR. Carrying a balance of $4,000 for even a few months can cost more in interest than many bonuses are worth. Treat the card like a debit card: only charge what is already in your bank account, and set up automatic payment of the full statement balance so no payment is ever missed. A missed payment can mean a late fee, a penalty interest rate, and damage to your credit history that lasts far longer than the bonus.
What usually counts, and what does not
| Usually counts | Usually does not count |
|---|---|
| Everyday purchases in stores and online | Balance transfers |
| Recurring bills that accept cards | Cash advances and cash equivalents |
| Subscriptions and memberships | Annual fees and interest charges |
| Purchases made by authorised users on the account | Purchases that are later returned or refunded |
The exact list is in the card’s terms. Returns are easy to overlook: if you buy something to reach the threshold and then return it, the refund reduces your qualifying spend, and the issuer can withhold or reverse the bonus.
Safe ways to reach the target
- Move recurring bills to the new card for the duration of the window: phone, internet, streaming, gym, insurance.
- Time the application before planned purchases rather than creating new ones.
- Add an authorised user you trust, such as a partner, and put household spending on one card.
- Prepay predictable expenses you would pay anyway, such as a utility bill paid in advance, where the provider allows it without a fee.
- Track progress in the issuer’s app. Some issuers show a live tracker; otherwise keep a simple note of qualifying purchases and dates.
Things to avoid
- Buying things you do not need to hit the number. The bonus becomes a discount on unnecessary spending.
- Paying fees to spend. Paying taxes or rent by card often carries a processing fee of around 2% or more, which eats into the bonus.
- Gambling transactions. Gambling and similar purchases are usually processed as cash advances or excluded, attract fees and immediate interest, and are banned on credit cards by some regulators. They should never be used to meet a minimum spend.
- Opening too many cards at once. Several minimum spends running together are hard to track and easy to miss.
The effect on your credit score
A new application usually triggers a hard inquiry, which can lower your score slightly for a short period. A new account also lowers the average age of your accounts. On the other hand, a higher total credit limit can lower your credit utilisation ratio, which helps, as long as balances stay low. For most people with good credit, the effect is modest and temporary when payments are on time. If you plan to apply for a mortgage or car loan in the coming months, it is sensible to wait.
Issuer rules on eligibility
Card issuers limit who can earn a bonus. Some restrict the welcome offer to people who have never held that card, or any card in the same family. Others limit bonuses if you have opened a certain number of new cards recently, or received a bonus on the same product within a set period. These rules are stated in the offer terms, and some issuers will tell you before you apply whether you are eligible. Read them first, because a declined bonus still leaves you with the hard inquiry.
A note on tax
In the United States, rewards earned for spending on a card are generally treated by the IRS as a rebate on your purchases rather than taxable income. Bonuses that do not require any spending, such as a reward for opening an account, can be treated differently. If in doubt, check with a tax professional.
The bottom line
A sign-up bonus is worth having only if the minimum spend fits your normal budget and you pay the balance in full every month. If either condition fails, the bonus is likely to cost more than it pays.
