iGaming Affiliate Economics: CPA vs Revenue Share

Affiliate marketing is the iGaming industry's own demand generation engine. Comparison sites, review portals, tipsters, streamers and media publishers send players to operators, and operators pay them for the customers they bring. How they are paid, a fixed fee per player or a share of that player's value, is a lesson in funnel maths and risk that any B2B marketer will recognise.
The three deal types
| Model | How it pays | Who carries the risk | Suits |
|---|---|---|---|
| CPA (cost per acquisition) | Fixed amount per qualifying first-time depositor | Operator: pays even if the player is worth little | Affiliates who want predictable cash flow; operators entering a market |
| Revenue share | A percentage of the net gaming revenue the player generates, for as long as the deal runs | Shared, mostly affiliate: income depends on player value and luck | Established affiliates with loyal, high-quality audiences |
| Hybrid | A smaller CPA plus a lower revenue share | Shared | Most negotiated deals between experienced partners |
A CPA usually comes with a baseline: the player must deposit a minimum amount, or wager a minimum amount, before the affiliate is paid. Revenue share is calculated on net gaming revenue (NGR), which is roughly what players lose to the operator minus bonuses, certain taxes and fees, depending on the contract. Revenue-share percentages vary widely by operator, market and volume; commission tiers often rise as an affiliate delivers more players.
The funnel maths
Whether CPA or revenue share is better depends on the expected value of the players an affiliate sends, which is a classic piece of reverse funnel maths. Here is an illustrative calculation with round numbers:
| Step | Assumption | Result |
|---|---|---|
| Visitors to a review page | per month | 50,000 |
| Click-through to operator | 8% | 4,000 |
| Registration | 25% | 1,000 |
| First deposit | 40% | 400 FTDs |
| Average NGR per FTD over 24 months | illustrative | $450 |
Under a $200 CPA, the affiliate earns 400 × $200 = $80,000 up front. Under a 30% revenue share, it earns 400 × $450 × 30% = $54,000, spread over two years, and only if the players behave as assumed. The operator's view is the mirror image: the CPA costs $80,000 now for players expected to produce $180,000 of NGR; the revenue share costs less in total but ties the operator to paying a share for as long as those players stay.
Change one assumption and the answer flips. If the affiliate's audience is high-value and loyal, so that average NGR per FTD is $1,200 instead of $450, the revenue share is worth $144,000. That is why experienced affiliates track player quality obsessively, and why operators set CPA levels by traffic source.
Details that change the numbers
- Negative carryover: if players win in a given month, NGR can be negative. Some contracts carry that deficit into following months; many affiliates negotiate to avoid it.
- Deductions: bonuses, payment fees, gaming taxes and platform fees may be deducted before the share is calculated. Read the definition of NGR closely.
- Lifetime versus fixed term: some revenue-share deals run for the life of the player; others end after a set period.
- Brand and terms changes: operators can revise commission plans, so long-term revenue share carries contract risk as well as player risk.
Regulation of affiliates
Regulators increasingly treat affiliates as an extension of the operator. In Great Britain the operator is accountable for what its affiliates publish. In many US states affiliates must hold a licence or registration before promoting operators there, and regulators in some states have questioned or restricted revenue-share arrangements. Marketing codes about bonus claims and audiences apply to affiliate content too. See compliance-aware marketing.
What B2B marketers can take from it
Affiliate economics is a clean example of a question every B2B marketer faces: do you pay for leads at a fixed price, or for outcomes? Paying per lead (CPA) is predictable but buys volume, not value; paying on outcomes aligns incentives but needs reliable tracking and patience. Most mature B2B partner and referral programmes end up hybrid, like iGaming. The deeper lesson is that the price of a lead should follow its expected value, which is the idea behind expected-value lead scoring, and that honest comparison content earns trust, as discussed in brand-agnostic content and the gating debate.
