Casino Bonuses Explained: Wagering Requirements and True Value
Last Updated: March 1, 2026
Casino bonuses are promotional credits whose real value depends on wagering requirements, not the headline dollar figure. A $1,000 deposit match with 30x playthrough at 96% RTP has an expected value of negative $200. A $500 bonus at 1x playthrough is worth $480.

Key Takeaways
- Bonus EV = Bonus Amount x (1 - WR x House Edge). Positive EV means the bonus has real value after clearing.
- FanDuel Casino’s 1x wagering requirement makes its bonus the highest-EV offer among major US operators.
- Most bonuses with 20x+ wagering on slots are negative EV — the clearing cost exceeds the bonus value.
- Free spins are typically worth $0.10-$0.25 per spin after wagering requirements on winnings.
- Use our wagering requirement calculator to compute true EV before accepting any offer.
How Do Casino Bonuses Actually Work?
A casino bonus adds promotional credits to your account, but those credits come with a wagering requirement (WR) — the number of times you must bet the bonus amount before withdrawal. The core formula:
Bonus EV = Bonus Amount x (1 - WR x House Edge)
The house edge is the inverse of RTP (Return to Player). A 96% RTP slot has a 4% house edge. Every dollar wagered costs 4 cents in expectation. At 30x wagering on a $1,000 bonus, you must place $30,000 in total bets to clear.
What Is the True Value of Common Bonus Offers?
The table below calculates expected value for representative bonus structures using 96% RTP slots (4% house edge), the most common game type for clearing bonuses.
| Bonus | Wagering Requirement | Game RTP | House Edge | Total Wagering | Expected Loss | Bonus EV |
|---|---|---|---|---|---|---|
| $500 match | 20x | 96% | 4% | $10,000 | $400 | +$100 |
| $1,000 match | 30x | 96% | 4% | $30,000 | $1,200 | -$200 |
| $1,000 match | 1x | 96% | 4% | $1,000 | $40 | +$960 |
| $200 match | 10x | 96% | 4% | $2,000 | $80 | +$120 |
| $1,500 match | 25x | 96% | 4% | $37,500 | $1,500 | $0 (break-even) |
| $500 match | 15x | 97% | 3% | $7,500 | $225 | +$275 |
The pattern is clear: the breakeven point for a 96% RTP game is exactly 25x. Any requirement above that means you pay the casino for the privilege of clearing their bonus.
Which Bonus Types Exist at US Online Casinos?
Deposit Match: The casino matches your deposit at 100% (sometimes 50-200%) up to a cap. Most common welcome bonus. A “100% match up to $1,000” gives you $1,000 in bonus credits on a $1,000 deposit.
No-Deposit: Small credits ($10-$50) with no deposit required. Typically carry 30-50x wagering and $100-$500 max withdrawal caps.
Free Spins: A set number of spins on specific slots, typically $0.10-$0.50 per spin. Winnings carry their own wagering requirement.
Cashback: 10-25% of net losses returned as credits or cash. Some operators return cashback as withdrawable cash with no additional wagering.
Why Does FanDuel’s 1x Playthrough Matter?
FanDuel Casino’s 1x wagering requirement fundamentally changes the bonus math. A $1,000 bonus at 1x requires only $1,000 in total wagers. At 96% RTP, the clearing cost is just $40, yielding $960 in expected value — versus $400 EV on the same $1,000 bonus at BetMGM’s 15x requirement.
FanDuel’s offer is worth 2.4x more in expected dollars despite an identical headline. Operator quality depends on other factors covered in our best online casino rankings, but on pure bonus value, the 1x playthrough is unmatched. See our FanDuel Casino review for details.
How Should You Choose Which Games to Clear Bonuses On?
Not all games contribute equally to wagering requirements. Most casinos weight game contributions:
| Game Type | Typical WR Contribution | Effective Clearing Speed |
|---|---|---|
| Slots | 100% | Every $1 bet counts as $1 |
| Table Games (Blackjack, Roulette) | 10-20% | $1 bet counts as $0.10-$0.20 |
| Video Poker | 10-20% | $1 bet counts as $0.10-$0.20 |
| Live Dealer | 10-20% | $1 bet counts as $0.10-$0.20 |
| Craps / Baccarat | 0-10% | Often excluded entirely |
The paradox: blackjack has the best RTP (99.5%) but only contributes 10-20% to wagering. Clearing a 20x/$1,000 bonus through blackjack at 10% contribution requires $200,000 in wagers. Our analysis shows slots at 100% contribution are the rational clearing choice for most bonus structures despite the higher house edge.

FAQ
Q: What are wagering requirements?
A: Wagering requirements (also called playthrough or rollover) specify how many times you must bet the bonus amount before withdrawing any winnings. A $100 bonus with 20x wagering means you must place $2,000 in total bets before the bonus or its winnings become withdrawable. Each bet chips away at the requirement regardless of whether you win or lose. Most regulated US casinos set requirements between 1x and 30x.
Q: Which casino has the lowest wagering requirements?
A: FanDuel Casino offers the lowest wagering requirement among major US operators at just 1x playthrough. This means a $1,000 bonus only requires $1,000 in total wagers before withdrawal, making it by far the highest expected-value bonus in the market. BetMGM typically requires 15x, DraftKings 15x, and Caesars 10-15x. The 1x requirement makes FanDuel’s bonus worth approximately $960 in expected value versus $400 for a comparable 15x bonus.
Q: Are casino bonuses worth it?
A: It depends entirely on the wagering requirement and the games you play. A bonus with 1x playthrough (like FanDuel) is almost always worth taking — the expected value is close to the full bonus amount. A bonus with 25x+ wagering on slots (96% RTP) is negative expected value, meaning you’ll statistically lose more clearing the requirement than the bonus is worth.
