Wagering Requirement Calculator
Estimate the wagering in a bonus scenario, compare contribution rates and see how the calculation works.
This tool uses bonus-only wagering. Deposit Amount is used only in % of Deposit mode. If the terms apply wagering to bonus plus deposit, choose $ Amount and enter their combined amount. Use one currency throughout; the $ symbol is a display label. No currency conversion is performed.
Example assumptions: 100% game contribution, 3% house edge and $1.50 per spin or hand.
The presets are illustrative inputs, not verified terms for a casino or game. Modelled loss equals effective wager × assumed house edge. It assumes the full wagering amount is played; your balance may run out sooner. It does not predict your session result, withdrawal eligibility or whether a bonus is worth claiming.
This animation only illustrates progress through the calculated effective wager. It does not simulate game results, balance changes or a chance of completing wagering.
Each comparison uses bonus-only wagering and a fixed illustrative 3% house edge, independent of the preset above. Contribution must be greater than 0% and no more than 100%. These calculations do not rank or recommend offers.
How the Calculation Works
In a bonus-only example, a $100 bonus with a 35× multiplier gives a wagering target of $3,500. If a game contributes 10%, the effective wager is $35,000: $3,500 ÷ 0.10. These are worked examples, not advertised casino offers.
For terms that apply the multiplier to bonus plus deposit, a $100 bonus and $100 deposit at 35× give a $7,000 target before adjusting for contribution. In $ Amount mode, enter $200 to model that combined base. Check the bonus rules and the operator's current terms for the correct basis.
Modelled loss is effective wager × assumed house edge. Estimated spins or hands is effective wager ÷ assumed stake, rounded up. The model assumes all of that wagering can be completed and does not account for bankroll depletion, game volatility, maximum cashouts or excluded bets.

These values are illustrative assumptions. They are not typical-rate claims or verified terms for any operator. Moving the contribution slider keeps the selected house edge and stake assumptions; the assumption panel shows the current values.
| Example | Contribution | House edge | Stake per play |
|---|---|---|---|
| Slots | 100% | 3% | $1.50 |
| Table Games | 10% | 1% | $10 |
| Live Casino | 10% | 2.5% | $10 |
| Video Poker | 15% | 2% | $5 |
| Scratch Cards | 50% | 5% | $2 |
| Custom Example button | 100% | 4% | $1 |
RTP describes a long-run average, not the return you should expect in an individual session. The UK Gambling Commission explains this distinction in its RTP and house-edge guide.
Terms to Check Before Using a Bonus
- Wagering basis: bonus only or bonus plus deposit.
- Eligible games: contribution rates and excluded games or bets.
- Time and stake limits: the actual expiry and maximum permitted stake.
- Withdrawals: verification, cashout limits and what happens if a bonus is cancelled.
- Eligibility: location, age and account restrictions in the current operator terms.
Keep to a limit you can afford to lose. A calculated wagering target is not a reason to continue playing or add funds. See our responsible gambling information for support resources.
Frequently Asked Questions
Wagering requirements describe how much qualifying play is required under a bonus promotion. For a bonus-only example, $100 at 35× gives a $3,500 target before adjusting for game contribution. The applicable terms determine what play qualifies and when funds can be withdrawn.
A lower multiplier reduces the wagering target when every other input is the same. It does not establish that a bonus is profitable or suitable. Eligibility, game rules, time limits, stake limits and withdrawal conditions also matter. This tool does not recommend offers.
Contribution depends on the promotion and game. In an example with 10% contribution, $10 of eligible wagers counts as $1 toward the target. A game with 0% contribution cannot clear that target. Check the current operator terms; the presets here are illustrative only.
This calculator cannot determine withdrawal eligibility. Check the applicable withdrawal rules and how accepting or cancelling a bonus affects your deposit, bonus balance and winnings. Ask the operator to clarify anything unclear before accepting a promotion.
Read the promotion terms for the actual expiry and the treatment of any remaining bonus or winnings. This calculator does not track an expiry or determine which funds can be withdrawn. An approaching deadline is not a reason to spend more than your limit.
Use the basis stated in the current promotion terms. This calculator uses bonus-only wagering. To model a combined bonus and deposit, select $ Amount and enter their combined amount. Deposit Amount affects the calculation only in % of Deposit mode.
