What does a 35x wagering requirement mean for your example? Calculate the bonus amount, required wagering, and theoretical expected loss using transparent formulas.
From bonus amount to required wagering
Enter all amounts in the same currency, such as euros or USDT.
With the default values: 100 bonus, 3,500 in required wagering, and 140 in theoretical expected loss.
This is not a winnings calculator. The model assumes you can complete all required wagering. Your balance may run out before then. The model does not account for variance, stopping early, deadlines, or withdrawal rules.
The formulas behind the result
- Bonus amount: Deposit × bonus percentage ÷ 100.
- Required qualifying wagering: Base amount × wagering multiplier. The base amount is either the bonus alone or the deposit plus bonus.
- Required total wagers: Required qualifying wagering ÷ (game contribution ÷ 100). A game with a 50% contribution doubles the total amount you need to wager.
- Theoretical expected loss: Total wagers × (1 − RTP ÷ 100). This is a statistical value across many sessions, not a prediction for a single session.
One multiplier, two very different requirements
Example: 100 deposit, 100 bonus, 35x wagering, 100% game contribution, and an assumed RTP of 96%.
| Base amount | Total wagers | Theoretical expected loss |
|---|---|---|
| Bonus only | 3,500 | 140 |
| Deposit + bonus | 7,000 | 280 |
A lower game contribution increases the amount you need to wager, but not your bonus. At a 50% contribution, 3,500 units of required qualifying wagering become 7,000 units in total wagers. With the same assumed RTP, the theoretical expected loss rises to 280.
What else to check before deciding
Check the maximum bonus amount, excluded games, the actual RTP version, the wagering deadline, maximum bets, and winnings caps. The calculator does not account for a bonus cap or changes to game rules, and no result is an invitation to gamble.
