How it is calculated
- Amount to wager = (bonus, or bonus + deposit) × wagering requirement ÷ game contribution. A 100 bonus at 35x on a game that counts 50% needs 7,000 in bets, not 3,500.
- Expected cost = amount to wager × house edge. On average you lose the house edge on every bet you place, so a 3% edge on 3,500 of bets costs about 105.
- Rakeback returns a share of that edge. Entered as a percentage of the house edge, it reduces the cost.
- Average value = bonus − expected cost + rakeback. Positive means the bonus is worth more than clearing it costs, on average.
What the number does not include
- Going bust first. With high variance games you may lose the whole balance before finishing the wagering. Real results spread widely around the average: try the variance calculator.
- Max cashout. Some bonuses cap what you can withdraw. If the cap is below the average value, the cap wins.
- Max bet and excluded games. Breaking these rules while wagering can void the bonus and its winnings.
