Check the basis
A 35× requirement on bonus funds is very different from 35× applied to both the deposit and bonus. The promotion terms should state which basis is used.

How to read your result: the headline bonus is only one part of the offer
Check game contribution
If a game contributes only 10%, every 10 wagered reduces the requirement by just 1. Games with 0% contribution do not reduce it at all.
Check the other limits
Maximum bets, excluded games, time limits and withdrawal restrictions are not captured by a single multiplier but can materially affect an offer.
Important: This calculator explains the arithmetic in published bonus terms. It cannot determine whether an offer is suitable or guarantee that a withdrawal will be approved. Always read the operator's current terms and avoid depositing more merely to reach a promotional limit.
How the calculator turns bonus terms into a result
The calculator follows the figures stated in a promotion rather than trying to rate the offer. Start with the amount you plan to deposit and the advertised match percentage. If the promotion limits the bonus to a maximum amount, enter that cap as well: a 100% match does not necessarily double every deposit when the available bonus stops at a fixed ceiling.
Bonus funds and starting balance
Bonus funds are calculated by multiplying the deposit by the match percentage, subject to any maximum-bonus cap. The starting balance combines your deposit with the resulting bonus. If you enter the deposit first, the calculator shows that amount immediately and adds the bonus once the match percentage is available.
The wagering basis changes the answer
The multiplier needs a basis. When terms say 35× bonus, the calculator applies 35 to the bonus funds only. When they say 35× deposit and bonus, it applies the same multiplier to the complete starting balance. Selecting the wording that actually appears in the promotion is more important than the multiplier by itself.
35× bonus only
100 × 35 = 3,500
Based on a 100 deposit and a 100% match.
35× deposit + bonus
200 × 35 = 7,000
The same headline offer produces twice the target.
Game contribution adjusts qualifying progress
A 100% contribution means every unit wagered counts fully towards the requirement. At 20% contribution, only one fifth counts, so five times as much play would be needed to produce the same qualifying progress. Use the contribution for the game or category you intend to play, not a general figure taken from another part of the terms.
The play-through target is cumulative qualifying stakes, not an amount the calculator predicts you will lose. Balance changes depend on game results, volatility and the house edge. Our wagering requirements guide explains those wider mechanics and restrictions in more depth.
What the calculated target does not tell you
A correct arithmetic result does not establish whether a promotion is good value or whether every wager will qualify. Before accepting an offer, check the conditions that sit alongside the multiplier:
- Maximum bets: exceeding the permitted stake while wagering is active can invalidate bonus winnings.
- Excluded games: some games contribute nothing, while others count at a reduced rate.
- Expiry periods: the requirement may need to be completed within a fixed number of days.
- Maximum cashout: the amount available to withdraw can be capped even after wagering is complete.
- Eligibility: country, currency, payment method and account-history restrictions may apply.
These conditions can make a smaller, clearer promotion more practical than one with a larger advertised maximum. The current listings in our casino bonus archive show the structured offer details available when each bonus was checked, but the operator's current terms remain decisive.
