Casino Bonus Wagering Calculator
Enter your deposit, match percentage, wagering multiplier, bonus base (deposit-only vs deposit-plus-bonus) and game contribution. The calculator returns the real turnover required to clear the bonus, plus the expected loss given the game's RTP. It is the single most useful sanity check before clicking "Claim Bonus".
How to read the output
Required turnover is the total amount you must bet before the bonus and any bonus-derived winnings become withdrawable. If you deposit A$50 with a 100% match and a 40× D+B multiplier, your obligation is (A$50 + A$50) × 40 = A$4,000. That is total stake, not total loss.
Expected loss is the house-edge cost of clearing the turnover: required turnover × (1 − RTP). At 96% RTP on A$4,000 turnover, the expected loss is approximately A$160. Short-term variance is enormous — the calculator shows the long-run mean.
Net expected position is the cold-blooded answer to "is this bonus worth it?". Start with deposit + bonus, subtract expected loss. If the result is negative, the bonus is an entertainment subsidy, not a profit opportunity. If positive — which is rare with 40× D+B at typical game RTPs — there is genuine positive expected value, usually only found on bonus-only wagering at low multipliers (≤25×) on high-RTP games (≥97.5%).
What the calculator does not account for
- Maximum bet during wagering. Most operators cap bets at A$5 while a bonus is active. Exceeding it voids the bonus — not the turnover that has accrued, the entire bonus. The calculator assumes you stay within the cap.
- Excluded games. Some promotions exclude specific titles entirely (not 0% contribution, simply banned). Playing a banned title while a bonus is active typically voids the bonus.
- Withdrawal limits. Many bonus terms cap the maximum winnings that can be withdrawn from a bonus balance — often A$2,000 or 10× the bonus amount. The calculator treats the balance as freely withdrawable; check the operator's T&Cs.
- Game volatility. Clearing A$4,000 turnover on a low-volatility game (Starburst, Sugar Rush) usually leaves you close to the expected-loss value. Clearing it on a high-volatility game (Dead or Alive II, The Dog House Megaways) produces wild swings; you might clear it profitably or blow out the bonus early.
- Time limit. Bonuses carry 5–14 day expiry. If you do not clear the turnover in time, any bonus-derived winnings are forfeited. The calculator does not model how realistic the time-to-clear is at your typical session size.
Worked examples — AU operators, April 2026
Scenario 1 — A$50 deposit at RocketPlay
100% match, 40× D+B wagering, 7-day expiry, slots at 96% RTP. Required turnover: A$4,000. Expected loss: A$160. Net expected: −A$110. Conclusion: A$110 of entertainment subsidy in exchange for locked funds for up to 7 days — reasonable if you would have played anyway.
Scenario 2 — A$50 deposit at Jackpot Jill
100% match, 50× D+B wagering, 5-day expiry, slots at 96% RTP. Required turnover: A$5,000. Expected loss: A$200. Net expected: −A$150. Conclusion: 25% stricter than RocketPlay at the same deposit; same subsidy logic but shorter window to clear.
Scenario 3 — A$250 VIP deposit at JokaRoom
100% match, 60× D+B wagering, 7-day expiry, slots at 96% RTP. Required turnover: A$30,000. Expected loss: A$1,200. Net expected: −A$700. Conclusion: bonus is a genuinely aggressive sink — at this size it primarily serves to extend play rather than deliver value.
Scenario 4 — A$50 at RocketPlay, played on live-dealer blackjack
100% match, 40× D+B, live-dealer contribution 5%. Required turnover on contribution-counted stake: A$4,000. But each A$1 staked only counts A$0.05, so actual turnover to clear: A$80,000. Expected loss at blackjack's typical 99.5% RTP: A$400. Conclusion: the bonus is functionally unusable for live-dealer play. This is the #1 hidden gotcha in every AU welcome promotion.
