Bonus Math
Understanding the true value of a bonus requires a simple mathematical model. Consider a welcome bonus: 100% match up to €200 with a wagering requirement of 35x the bonus amount. If you deposit €100 and receive a €100 bonus, your total bankroll is €200. The wagering requirement is €100 × 35 = €3,500.
Assuming an average game RTP of 96% (house edge 4%), the expected loss during wagering is €3,500 × (1 – 0.96) = €140. Since your initial deposit is €100 and the bonus is €100, your effective value is (€200 – €140) – €100 (your deposit) = -€40. This means you are likely to lose €40 on average before meeting the wagering. However, some games contribute differently to wagering (e.g., slots 100%, table games 10%), so actual figures may vary.
Formula: Expected Value = (Deposit + Bonus) – (Wagering Requirement × (1 – RTP)) – Deposit
For a €100 deposit and €100 bonus with 35x wagering at 96% RTP: EV = €200 – (€3,500 × 0.04) – €100 = €200 – €140 – €100 = -€40.
