Bonus Math
Understanding the mathematics behind bonuses helps you make informed decisions. Consider a typical welcome bonus: 100% match up to $500, with a 40x wagering requirement on the bonus amount only.
Formula: Wagering requirement = Bonus amount × Wagering multiplier.
If you deposit $100, you receive a $100 bonus. The wagering requirement is $100 × 40 = $4,000. You must wager $4,000 before withdrawing any winnings from the bonus.
Assuming a slot game with 96% RTP, the expected loss per $1 wagered is 4%. Over $4,000, the expected loss is $4,000 × 0.04 = $160. Since you only deposited $100, the expected value is negative. However, by choosing games with higher RTP and lower house edge, you can improve your chances.
Another calculation: effective bonus value = bonus amount – (wagering requirement × house edge). For $100 bonus with 40x and 4% house edge: $100 – ($4,000 × 0.04) = $100 – $160 = -$60. This shows the bonus has negative expected value unless you play games that contribute less to wagering (e.g., slots at 100% vs. table games at 10% or 20%).
