Top 5 Commission Calculation Mistakes iGaming Operators Make (And How to Fix Them)

Across hundreds of operator conversations, the same handful of commission errors come up again and again. Most are small individually. Compounded across dozens of affiliates and multiple brands, they quietly cost operators thousands of dollars every month - and more importantly, they erode affiliate trust.

1Wrong tier breakpoints

Tiered Rev Share plans (e.g. 25% up to $10k NGR, 30% above, 35% above $30k) are easy to misconfigure. The most common mistake: applying the higher tier to the entire NGR once the threshold is crossed, instead of only the incremental portion. For high-volume affiliates, this silently overpays or underpays by 3-8% month after month.

2Ignoring negative carryover

When a player wins big in month one, the affiliate's NGR can be negative. Forgetting to carry that deficit into the next calculation period (or carrying it forward indefinitely without a reset policy) is one of the biggest sources of dispute. Either the operator overpays, or the affiliate loses faith in your reporting.

3Counting re-deposits as FTDs

For CPA plans, an FTD (first-time deposit) is a one-shot event. When player data is re-imported or deduplicated badly, the same player can be counted as an FTD twice - once per brand, or once per import batch. A small CPA of $150 multiplied by hundreds of duplicate events adds up fast.

4Not separating brand commissions

Multi-brand operators often apply a single commission plan across all their casino sites. But brands have different margins, different bonus structures, and different regulatory costs. A 30% Rev Share that's profitable on your sportsbook brand may be loss-making on your live casino brand. Commission plans should be configured per-brand, not globally.

5Mixing gross and net revenue definitions

Your affiliate contract says "25% of net revenue" - but net of what? Net of bonuses? Net of chargebacks? Net of gaming tax? Every operator defines NGR slightly differently, and if that definition is not hard-coded into the commission engine, manual calculations inevitably drift.
