How Welcome Bonuses Really Work (and How to Value Them)

The welcome bonus is the single largest line in most cards' first-year value — and the most misleadingly advertised number in the industry. Here's how to read one properly.

The anatomy of a bonus

A typical Canadian offer: "Earn up to 60,000 points." The load-bearing words are up to. That total usually decomposes into:

• A chunk for hitting a minimum spend in the first 3 months (say, $3,000–$7,500).
• A chunk dripped monthly for hitting a spend target each month (the Cobalt model).
• Sometimes a chunk for keeping the card past year one — deliberately placed after your first annual fee renews.

Each structure changes the real value. A drip bonus requires twelve months of discipline; an anniversary bonus is really a year-two retention offer priced into year-one marketing.

Valuing a bonus in dollars: a worked example

Points × our index valuation = gross value. Then subtract:

1. The annual fee (unless genuinely waived — check whether "first year free" requires a fee-bearing companion product).
2. Forced spend friction. If a $6,000 minimum spend pushes you beyond your natural spending, the excess isn't free — you're buying points.
3. The earn you gave up on your existing card during the qualification period.

Take a card offering 50,000 points on $4,000 of spend in 90 days, on a $120-fee card, in a program we value at 1.9¢/point: gross bonus value is $950. If that $4,000 is spend you'd have made anyway on an existing 2%-cash-back card, you gave up $80 of foregone earn to chase it. Net: $950 − $120 (fee) − $80 (foregone earn) = $750 — a real number, and meaningfully lower than the $950 headline. That's the calculation behind the first-year net value we publish on every card page, and it's why two cards with identical headline bonuses can carry very different net figures once fees and spend patterns are factored in.

The eligibility rules that catch people

The single most common way people lose a bonus isn't spend-related at all — it's applying for a card you're not actually eligible for. Amex enforces a written once-per-lifetime-per-product rule: if you've held a specific Amex card before, its welcome bonus generally won't be available to you again, and Amex's own soft-check pre-qualification step exists specifically to catch this before it costs you a hard inquiry. Other issuers' reapplication rules are murkier — some published, most not — and worth understanding before you plan around a specific offer; we've broken down what's actually documented versus assumed, issuer by issuer, in our full eligibility rules guide.

Beyond eligibility, a few mechanical rules trip people up on the math itself:

• Returned/refunded purchases don't count toward minimum spend.
• Annual fees don't count toward minimum spend either.
• Quebec residents often see different offer structures.

When a great bonus is a bad reason

A bonus is one year; earn rates and fees are forever. A card with a 9/10 bonus and 4/10 ongoing value is a card you'll be cancelling in 13 months — fine if that's the plan, expensive if it isn't. Our Standard Score weights first-year value at 30% for exactly this reason: big, but not decisive. For a concrete look at what "the bonus is gone — now what?" actually looks like on specific cards, see our application and year-two math breakdowns for the Amex Cobalt and Amex Platinum.
