Wagering Requirement Calculator: True Casino Bonus Value
By Odds Reference Published March 1, 2026 Updated July 19, 2026 Editorial Policy
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 on slots, turning it into negative $100. This calculator reveals a bonus’s true dollar value.
Run your own numbers with the interactive wagering requirement calculator — enter any bonus amount, wagering multiple, and game RTP to see the exact expected value before you opt in.

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?
True bonus value equals the bonus amount minus the expected loss incurred while clearing the wagering requirement. The formula is bonus amount minus wagering amount times house edge, where wagering amount is the bonus (or deposit plus bonus) multiplied by the wagering multiplier. Lower multipliers and lower-edge games both preserve more value.
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.
Wagering multiples and game contribution rates are set by the operator and change without notice — we verified the FanDuel and BetMGM figures above against published bonus terms as of July 2026. Licensed U.S. operators must file bonus and promotional terms with state regulators such as the New Jersey Division of Gaming Enforcement and the Pennsylvania Gaming Control Board, but the terms themselves remain the operator’s to set and change. Confirm current terms directly on the operator’s promotions page before opting into any bonus.
How Does Game Selection Affect Wagering Cost?
Casinos know that house edge determines the true cost of clearing a wagering requirement, which is why most bonus terms restrict which games count toward playthrough or weight contributions unequally. Full-odds slots typically contribute 100% of every bet, while lower-edge table games like blackjack often contribute only 10-20%.
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.
Always read bonus terms to identify contribution rates — the ranges above reflect typical published terms as of July 2026 and vary by operator. Our best online casino guide compares bonus terms across major US operators, and the game comparison calculator ranks house edge across every game type.
What Is the FanDuel vs BetMGM Bonus Comparison?
FanDuel’s 1x wagering requirement and BetMGM’s 15x requirement apply to the same $1,000 deposit-match bonus, showing why the wagering multiple matters more than the headline figure. The table below breaks out expected loss and true value for both operators across blackjack and slots, with and without game-contribution weighting.
| 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.

Chasing a wagering requirement is not a bankroll strategy — set a loss limit before you opt into any bonus.
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.
Q: Does game contribution weighting change the math?
A: Yes, significantly. Contribution weighting counts only a fraction of each bet toward the requirement for certain games. A 10% blackjack contribution means a $500 bonus at 15x wagering requires $75,000 in actual blackjack bets, not $7,500. That raises expected loss from $37.50 to $375, cutting into the low-edge advantage blackjack normally provides.
Q: Do sweepstakes casino wagering requirements work the same way?
A: Yes. Sweepstakes casinos issue bonus Sweep Coins (SC) redeemable for cash at 1 SC = $1, so a 1x playthrough requirement on SC bonuses costs exactly the same in expected value as an identical requirement at a real-money casino. A 20 SC bonus at 1x on a 96% RTP game loses $0.80 in expectation, leaving $19.20 in true value.
