Calculating Your Bonus
\n
Most welcome offers are deposit match bonuses with wagering requirements. Let’s use a typical offer: 100% match bonus up to $500 with a 30x wagering requirement on the deposit plus bonus amount.
\n
Example calculation: You deposit $200. The casino gives you a $200 bonus. Your total balance becomes $400. The wagering requirement is 30 × (deposit + bonus) = 30 × ($200 + $200) = 30 × $400 = $12,000. You must wager $12,000 on eligible games before you can withdraw any winnings from the bonus.
\n
If you only play slots that contribute 100% to wagering, you need to place $12,000 in bets. Suppose the average slot RTP is 96%, your expected loss during wagering is $12,000 × (1 – 0.96) = $480. This is the theoretical cost to clear the bonus. With a $200 deposit and $200 bonus, your net expected value is $200 – $480 = -$280. However, if you choose games with higher RTP (e.g., blackjack with 99.5% RTP but only 10% contribution), the effective wagering requirement becomes $12,000 / 0.10 = $120,000, which is worse. Always check contribution percentages and choose games that maximize your expected return.
