How to judge a credit card sign-up bonus
A big welcome bonus can be worth hundreds of dollars — but not every sign-up offer is as good as it looks. Before you apply, run the numbers like an underwriter. Here is the framework.
Step 1: Do the first-year value math
Add up everything the card gives you in year one, then subtract what it costs:
- Welcome bonus value — convert points to travel or cash value honestly; they are rarely worth the headline "up to" figure
- First-year perks: statement credits, lounge passes, and insurance coverage worth real money to you
- Minus the annual fee, which is usually charged on day one
A card with a $250 fee and a bonus worth $600 still nets $350 in year one — a good deal. One offering $50 in cash back against a $120 fee is not.
Step 2: Check the minimum spend is realistic
Bonuses arrive only after you spend a set amount — often $2,000 to $5,000 — within three months. That is easy with normal spending for many households and impossible for others. If hitting the threshold means manufacturing purchases you would not otherwise make, the bonus is already more expensive than it looks. Never spend real money to earn pretend rewards.
Step 3: Read the fine print on caps and eligibility
- Some boosted earn rates apply only to the first slice of spending
- Enhanced offers often exclude anyone who held the card in the past 1 to 2 years
- Time limits matter: miss the spend window and the bonus vanishes
Step 4: Does the card earn its keep after year one?
The welcome bonus is the first date; the ongoing earn rate, insurance, and perks are the relationship. Compare the card's everyday value — points on groceries, gas, and recurring bills — against the fee in year two and beyond.
Tip: Calculate your annual-fee break-even: the yearly spending needed for rewards to outpace the fee. If your real spending cannot clear it, a no-fee card is mathematically better regardless of the sign-up offer.
The bottom line
Sign-up bonuses reward organized spenders and punish everyone else. If the minimum spend fits your natural budget and the card still makes sense in year two, apply and collect. If not, the flashiest offer in Canada is still the wrong card for you.
