Bonus cost calculator
A bonus with a wagering requirement is only worth what is left after the player has staked enough to release it. This calculator shows the turnover a bonus requires, the expected loss while clearing it, and the break-even wagering multiple for a game's RTP.
The formulas
- Required turnover = wagering multiple × (bonus, or bonus plus deposit) ÷ game contribution.
- Expected loss while wagering = turnover × (1 − RTP).
- Expected value of the bonus to the player ≈ bonus − expected loss. The break-even wagering multiple is 1 ÷ (1 − RTP) on bonus-only terms.
Worked example
A bonus of 100 with a 35× wagering requirement on the bonus requires 3,500 in stakes. On a game with an RTP of 96%, the expected loss while wagering is 140, more than the bonus itself. At that RTP the break-even requirement is 25×.
This is the average over many players, under simplified assumptions. Many players bust before completing the requirement, which lowers the operator's actual cost, and maximum-bet and game restrictions change it further. Terms must also follow local rules, which in some markets cap or ban wagering requirements.
