Wagering Requirement Calculator: True Casino Bonus Value
Last Updated: March 1, 2026
A casino bonus is worth its face value minus the expected loss incurred while completing the wagering requirement. A $500 deposit match at 1x wagering (FanDuel) retains roughly $497 in expected value on blackjack. The same $500 at 30x wagering loses $600 during playthrough on slots, making it worth negative $100. This calculator shows the true dollar value of any bonus.

Key Takeaways
- True bonus value = bonus amount - (bonus x wagering multiplier x house edge). This formula determines whether accepting a bonus is profitable.
- FanDuel’s 1x wagering requirement preserves 95-99% of bonus value. BetMGM’s 15x requirement preserves 70-93% depending on game choice.
- Game selection during wagering is critical. Blackjack playthrough costs $0.50 per $100 wagered; slots cost $4.00 per $100 wagered.
- Some bonuses are mathematically negative EV — the expected loss during playthrough exceeds the bonus itself.

How Do You Calculate True Bonus Value?
The core formula:
True Value = Bonus Amount - (Wagering Amount x House Edge)
Where wagering amount = bonus x wagering multiplier (for bonus-only wagering) or (deposit + bonus) x wagering multiplier (for deposit-and-bonus wagering).
Most US-regulated online casinos apply wagering to the bonus only. Some offshore or sweepstakes operators apply wagering to deposit plus bonus, which doubles the required volume.
| Bonus | Wagering Req | Wagering Amount | House Edge | Expected Loss | True Value |
|---|---|---|---|---|---|
| $500 | 1x (FanDuel) | $500 | 0.50% (BJ) | $2.50 | $497.50 |
| $500 | 1x (FanDuel) | $500 | 4.00% (slots) | $20.00 | $480.00 |
| $500 | 15x (BetMGM) | $7,500 | 0.50% (BJ) | $37.50 | $462.50 |
| $500 | 15x (BetMGM) | $7,500 | 4.00% (slots) | $300.00 | $200.00 |
| $500 | 30x | $15,000 | 0.50% (BJ) | $75.00 | $425.00 |
| $500 | 30x | $15,000 | 4.00% (slots) | $600.00 | -$100.00 |
| $500 | 50x | $25,000 | 4.00% (slots) | $1,000.00 | -$500.00 |
The 30x and 50x requirements turn a $500 bonus into a net loss on slots. This is a fact obscured by marketing copy that emphasizes the bonus amount without contextualizing the playthrough cost.
How Does Game Selection Affect Wagering Cost?
Casinos know that house edge determines wagering cost. This is why most bonus terms restrict which games contribute to wagering — or weight game contributions unequally.
Common contribution weightings:
| Game Type | Typical Contribution | Effect on Wagering |
|---|---|---|
| Slots | 100% | $100 bet = $100 toward requirement |
| Roulette | 20-50% | $100 bet = $20-$50 toward requirement |
| Blackjack | 10-20% | $100 bet = $10-$20 toward requirement |
| Video Poker | 10-20% | $100 bet = $10-$20 toward requirement |
| Baccarat | 10-20% | $100 bet = $10-$20 toward requirement |
| Live Dealer | 10-50% | Varies by operator |
A 10% blackjack contribution means you need to wager 10x as much in actual dollars to meet the requirement. A $500 bonus at 15x with 10% blackjack contribution requires $75,000 in blackjack bets (not $7,500). Expected loss at 0.5% edge: $375. The bonus is still positive EV at $125, but contribution weighting erodes much of the advantage of playing a low-edge game.

What Is the FanDuel vs BetMGM Bonus Comparison?
This comparison illustrates why wagering requirements matter more than headline bonus amounts.
| Factor | FanDuel Casino | BetMGM Casino |
|---|---|---|
| Max Bonus | $1,000 deposit match | $1,000 deposit match |
| Wagering Requirement | 1x bonus | 15x bonus |
| Total Wagering Needed | $1,000 | $15,000 |
| BJ Expected Loss | $5.00 | $75.00 |
| Slots Expected Loss | $40.00 | $600.00 |
| True Value (BJ) | $995.00 | $925.00 |
| True Value (Slots) | $960.00 | $400.00 |
| BJ Contribution | 100% | 20% |
| Adj. BJ Wagering Needed | $1,000 | $75,000 |
| Adj. BJ Expected Loss | $5.00 | $375.00 |
| Adj. True Value (BJ) | $995.00 | $625.00 |
FanDuel’s 1x requirement with 100% blackjack contribution delivers $995 in expected value. BetMGM’s 15x with 20% blackjack contribution delivers $625. The headline $1,000 figure is identical, but the realized value differs by $370.

How Should You Evaluate Sweepstakes Casino Bonuses?
Sweepstakes casinos operate under a different model — you purchase Gold Coins and receive bonus Sweep Coins (SC). Since SC can be redeemed for cash at 1 SC = $1, wagering requirements on SC bonuses function identically to traditional casino bonus requirements.
A typical sweepstakes offer: purchase $20 in Gold Coins, receive 20 bonus SC with 1x playthrough. Expected loss at 96% RTP: $0.80. True value: $19.20.
The key difference is that sweepstakes casino RTP data is less transparent than regulated iCasino platforms. Our analysis of sweepstakes casino RTP configurations shows that published values are not always verifiable by third-party labs.
FAQ
Q: How do wagering requirements reduce bonus value?
A: Wagering requirements force you to bet a multiple of your bonus before withdrawing. Each dollar wagered loses a fraction equal to the house edge. A $100 bonus with 20x wagering requires $2,000 in bets. At 4% house edge (typical slots), expected loss is $80, reducing the bonus to $20 in expected value. Higher wagering requirements or lower-RTP games can push expected value below zero.
Q: Which casino has the best wagering requirements?
A: FanDuel Casino offers the industry-best 1x wagering requirement on deposit match bonuses. A $1,000 match at 1x requires just $1,000 in total bets. At 0.5% house edge (blackjack), expected loss during playthrough is $5.00, making the bonus worth approximately $995. BetMGM’s 15x requirement on the same bonus reduces expected value to approximately $925 on blackjack or $400 on slots.
Q: Can a casino bonus have negative expected value?
A: Yes. A bonus becomes negative EV when the expected loss during wagering exceeds the bonus amount. For example, a $50 bonus with 50x wagering requires $2,500 in bets. Playing keno at 25% house edge, expected loss is $625 — making the bonus worth negative $575. Even on slots at 4% edge, expected loss is $100, which exceeds the $50 bonus. Always calculate before accepting.
