This calculator provides mathematical estimates based on RTP and volatility. Actual results will vary due to the random nature of gambling. Always read the full bonus terms before accepting.

Frequently Asked Questions
Wagering requirements define how many times you must bet a bonus amount before you can withdraw it. A 100 bonus with 35x wagering means you must place bets totalling 3,500 before a withdrawal is possible.
The calculator multiplies the wagering base (bonus only, deposit only, or bonus plus deposit) by the wagering multiplier. For example, a 100 bonus with 35x bonus-only wagering results in 3,500 to wager.
Bonus Only applies the multiplier to the bonus amount alone. Deposit Only applies it to your deposit alone. Bonus plus Deposit applies it to both combined, which makes the requirement significantly larger and harder to clear.
Bust probability is the estimated chance of losing your entire balance before completing the wagering requirement. It is influenced by your starting balance, bet size, game RTP and volatility. A high bust probability means the bonus is very risky.
Profit probability is the estimated chance of finishing the wagering with more than your starting balance. Even when a bonus looks generous, the house edge usually keeps this probability low across the full requirement.
It depends on the RTP of the permitted games. At 96% RTP with 35x bonus-only wagering the expected loss equals the bonus amount, making the expected value close to zero. Higher wagering or lower RTP pushes the bonus firmly into negative expected value.
