Not all commission works the same way — knowing the difference changes which programs are actually worth your time.
"Affiliate commission" isn't one single structure — it's a category that covers several genuinely different payment models. Understanding the differences matters, because two programs with the same headline commission percentage can produce very different real-world income depending on which model they use.
A fixed payout for a specific action — usually a sale, but sometimes a signup, trial start, or lead. You know exactly what you'll earn per conversion, which makes it predictable, but it's a one-time payment regardless of how much the customer ends up spending long-term.
A percentage of the actual sale value, rather than a fixed amount. This scales with order size — a $200 order pays more than a $20 order at the same rate — which rewards promoting higher-value products or encouraging larger purchases.
Payment for generating a qualified lead, not necessarily a completed sale — common in industries with a longer sales cycle, like insurance, finance, or B2B software, where the merchant's own sales team closes the actual deal afterward.
You earn commission every billing cycle a referred customer stays subscribed — not just once. This is often the single most valuable structure in affiliate marketing, since a modest percentage compounds into significant income if retention is genuinely strong. A 20% commission on a $50/month tool, retained for two years, pays $240 — many times what a one-time CPA payout on the same customer would.
Similar to recurring commission, but often applied more broadly — an ongoing percentage of whatever revenue a referred customer or account generates over time, not necessarily tied to a fixed subscription price.
Promoting expensive products or services — often $500 to several thousand dollars per sale — where even a modest conversion rate can produce meaningful income, because each individual sale is worth so much. The tradeoff: high-ticket buyers usually convert at a lower rate and need more trust-building content before they'll commit.
A program's headline commission rate is only half the picture — the model behind it determines what that rate is actually worth in practice. This is exactly the distinction covered program-by-program across our full library of affiliate program reviews, where we break down not just the rate, but the actual structure behind it for each program.
