Credit card sign-up bonus minimum spend, priced honestly
2 min read · Card offers, Strategy
Treat a credit card sign-up bonus as net value after the purchases you would not have made, the annual fee in the first year, and any category you would otherwise run on a higher-earn card. Divide the bonus by the minimum spend only after you strip those costs. If the leftover cents per dollar beat your everyday card, the offer is still in play.

A credit card sign-up bonus is a marketing number wrapped around a spend schedule. 1
Price the schedule first. The headline second.
Map the spend you already have
List rent equivalents you can put on a card, insurance, utilities, groceries, and planned travel for the window the offer prints. If that list clears the minimum without new shopping, the offer is mostly about timing and the fee. If you need new purchases to clear it, those purchases are a cost, not a victory.

Net the fee and the displacement
Subtract the first-year annual fee from the bonus value you actually keep. Then subtract the rewards you give up by moving spend off a card that earns more in that category. What remains is the net bonus.
Example arithmetic for a $200 statement credit after $1,000 spend in 90 days with a $95 fee and $20 of displaced rewards: 200 - 95 - 20 = $85 net. $85 on $1,000 of planned spend is 8.5 cents per dollar before you value your time.
Compare offers on cents per dollar after costs
Two offers with different spends only become comparable after that netting step. A larger bonus with a larger spend can lose to a smaller one you clear with bills you already pay.
Watch the window and the statement cut
Issuers count posted transactions inside a window that starts on approval or account opening, depending on the page. A purchase on day 89 that posts on day 91 can miss. Keep a buffer of a few days and confirm the posted total in the issuer app, not just your receipt pile.
Bank bonuses are a different machine
Checking bonuses usually care about direct deposit and balance holds, not card spend. If you are stacking both, read bank bonus vs credit card sign-up offer before you overload one month of cash flow.
Common questions
Does every purchase count toward minimum spend?
Usually purchases post as purchases. Cash advances, balance transfers, and some fee categories often do not. Read the offer's own list; do not assume a grocery run counts if the page excludes it.
What if I already spend that much each month?
Then the minimum spend is mostly timing. Move the spend you already planned into the window, keep the better everyday card for categories the new card loses on, and still subtract the annual fee.
How do taxes work on a points welcome bonus?
Cash bank bonuses are often interest. Points and miles from a credit card welcome offer are usually treated differently for tax purposes, and the outcome can depend on how you redeem. When in doubt, ask a tax professional for your facts.
