🎰 Bonus maths: one formula gets it wrong

A bonus model shared by iGaming CEO argues many operators still use a linear formula that can misprice welcome offers. With a €500 bonus, 30x wagering and 96% RTP, that model produces -€100 EV — an impossible outcome. 📊 The alternative uses a geometric formula: EV = Bonus × RTP^Wagering, which gives €146.93, or a 29.4% bonus ratio. In simple terms, each wagering cycle reduces a smaller balance, not the original one. For casino teams, that means bonus cost — and margin — may be stronger than older models suggest. 🎯 Source: iGaming CEO Telegram, 27 July 2026.
