Bonus Wagering Calculator
Work out how much play a bonus requires, including games that contribute less than 100%. This is a simplified cost model, not a profit forecast or a recommendation to gamble.
Your bonus terms
Use the RTP and contribution for the exact game variant. If only 10% of a wager counts, clearing the same requirement takes ten times the stakes.
Playthrough and modelled cost
Enter the missing terms and check any highlighted inputs to calculate a result. Unknown values are not treated as zero.
The model assumes the full wagering target is reached at a constant RTP. It does not simulate volatility, running out of funds, withdrawal caps, expiry, max-bet breaches, fees or price changes. Actual losses can exceed the estimate. Legal-age players only.
Worked example: the same 40× bonus
A $100 deposit with a 100% match gives a $100 bonus. At 40× bonus-only wagering, $4,000 must count toward the requirement. A game with 100% contribution needs $4,000 in stakes; at 10% contribution it needs $40,000. At 96% RTP, those amounts imply modelled costs of $160 and $1,600 respectively.
If 40× applies to the deposit plus bonus instead, the credited target is $8,000. Always check which balance the multiplier applies to.
