Direct answer: calculate iGaming influencer ROI from a defined, realized return and a fully loaded campaign cost. Reconcile each attributed player in the operator account system, wait for the stated cohort window, and report projected value separately from realized value.
ROI, ROAS and contribution profit are different
| Metric | Formula | Use | Main limitation |
|---|---|---|---|
| ROAS | Attributed revenue ÷ media spend | Media efficiency | Can omit fees, bonuses and operating costs |
| ROI | (Return − campaign cost) ÷ campaign cost | Return on the investment | Meaningless unless “return” and cost scope are named |
| Contribution profit | Defined revenue − variable deductions − campaign cost | Incremental economics | Depends on the operator's agreed accounting policy |
| Cost per qualified FTD | Campaign cost ÷ qualified FTDs | Acquisition comparison | Does not show retention or player value |
State whether revenue means GGR, NGR or another accounting field. Name every deduction, including bonuses, payment fees, taxes, chargebacks and fraud adjustments where applicable. Never substitute deposits for revenue.
An auditable worked example
Synthetic example: a creator campaign has a $12,000 fee, $1,500 production/rights cost and $500 measurement cost. Fully loaded campaign cost is $14,000. After a 60-day observation window, the reconciled cohort has $22,000 of realized NGR under the operator's documented definition.
- ROAS using NGR and the creator fee only: $22,000 ÷ $12,000 = 1.83.
- Contribution profit after the full campaign cost: $22,000 − $14,000 = $8,000.
- ROI: $8,000 ÷ $14,000 = 57.1%.
- If there were 140 qualified FTDs, cost per qualified FTD: $14,000 ÷ 140 = $100.
The example does not establish a benchmark. If $22,000 were a forecast rather than realized NGR, label the result “projected ROI” and preserve the model version and assumptions.
Run your own inputs in the iGaming ROI and CPA calculator, then export the assumptions alongside the result.
Build the measurement record
- Freeze definitions: campaign cost, qualified registration, qualified FTD, active player, NGR and exclusions.
- Assign identifiers: one creator ID across UTMs, referral links, codes and the operator ledger.
- Deduplicate: apply a written precedence rule when a player has both a link and a code.
- Reconcile: compare click records with accepted accounts, payments, fraud status and later reversals.
- Mature the cohort: report early acquisition separately from D30/D60 value.
- Separate fact from model: keep realized revenue, forecast value and assisted conversions in separate fields.
Minimum audit table
| Field | Owner | Control |
|---|---|---|
| Spend and rights | Finance/procurement | Invoice and contract reconcile |
| Clicks and campaign IDs | Analytics | UTM naming and invalid-traffic checks |
| Registration/FTD status | Operator data | Account ID, eligibility and payment status |
| NGR and deductions | Finance/data | Versioned definition and close date |
| Attribution decision | Marketing analytics | Window, precedence and exception log |
For implementation, use the click-to-depositor tracking architecture. For campaign planning, compare channels in the affiliate versus influencer decision matrix.
