How a "lost player" is defined in iGaming
Unlike SaaS, where a customer actively cancels a subscription, online betting has no equivalent explicit trigger — a player simply stops depositing or opening a session. That's why churn in iGaming is defined through an inactivity window: a stretch with no deposit and no session, after which the player is counted as lost.
The size of that window depends on the product. A slots or live casino player typically shows high frequency, so a 30-day pause is already a strong abandonment signal. A sportsbook bettor, on the other hand, can disappear for 60 to 90 days between seasons or competitions without having actually left the operation — they come back when the sporting calendar they care about resumes. Using the same window for both profiles distorts the number: applying 30 days to sportsbook inflates reported churn; applying 90 days to casino delays detecting a player who has already left.
Monthly churn vs. cohort churn
Simple monthly churn divides players lost in the month by total active players at the start of the month. It's quick to calculate, but it hides a problem: if the operation is acquiring a lot of new players, the month's active base grows artificially and the churn percentage looks lower than it really is, because the denominator is padded with players who haven't had time to leave yet.
Cohort churn fixes this by tracking a specific group of players who signed up in the same month and measuring how many are still active at D30, D60, D90, and so on. Two operations can post the same aggregate monthly churn while their cohorts follow completely different paths — one retaining well past the first month and another losing most players by the second week. Only cohort churn exposes that.
What drives churn at a betting operator?
Three causes account for most avoidable churn:
- Slow withdrawals — even with PIX (Brazil's instant bank-transfer rail), recurring delays or failures in settling a withdrawal are the most direct trigger for abandonment, because they break trust at the most sensitive moment.
- Stuck KYC — pending or rejected identity verification with no clear explanation blocks the withdrawal and pushes the player toward a competitor.
- A weak catalog — missing relevant providers, few crash games, and uncompetitive sportsbook odds send players to wherever the offer is better, even absent any dissatisfaction with payments.
Inactivity windows by product type
| Product | Common inactivity window | Why this window |
|---|---|---|
| Slots / casino | 30 days | Naturally high usage frequency; a short pause already signals risk |
| Sportsbook | 60–90 days | Sporting calendar seasonality creates normal gaps between competitions |
| Live casino / VIP | 45 days | High ticket size calls for a mid-range window — a longer pause is financially more sensitive |
