ARPU, average revenue per user, is total revenue over a period divided by the number of active users in that period. It is a headline health metric that summarises, in one number, how much value the average user is producing.
Definition
ARPU, average revenue per user, is total revenue over a period divided by the number of active users in that period. It is a headline health metric that summarises, in one number, how much value the average user is producing.
In iGaming, "revenue" usually means net gaming revenue (stakes minus wins minus bonus cost), and "user" means an active player, so ARPU is net gaming revenue divided by monthly active players.
ARPU is simple but coarse. It blends whales and minnows, new and tenured players, and different products, so a stable ARPU can hide a shrinking base of high-value players being replaced by a growing base of low-value ones.
It is most useful as a trend watched alongside active-user count, and as an input to segmented analysis rather than as a standalone target.
In context
Operators break ARPU down to make it actionable: ARPU by acquisition source and GEO (to judge traffic quality), by tenure cohort (to see whether players grow or decay in value), by product (casino versus sportsbook versus live), and by value segment (so the small share of high-value players is analysed separately from the long tail). A related metric, ARPPU (average revenue per paying user), divides revenue by only the users who deposited or wagered, isolating spend behaviour from activation rate.
For affiliates, the operator's ARPU for their referred cohort is the clearest signal of how a RevShare deal will perform: a brand with a high, stable ARPU among affiliate-sourced players will pay more over time than one whose affiliate cohorts have low ARPU, even at the same headline percentage. The usual mistakes with ARPU are comparing it across operators with different revenue definitions (gross versus net, bonus treatment), reacting to short-term swings driven by variance in a small whale population, and treating a blended figure as representative when the distribution is highly skewed.
Worked example
An operator's overall ARPU holds at $48, but segmented analysis shows ARPU for players older than 6 months rising to $70 while ARPU for the newest cohort has fallen to $28. The base is being refreshed with lower-value players; the operator investigates the acquisition mix rather than celebrating the flat headline number.
