Wagering requirement calculator
Enter the offer as the casino's bonus terms describe it. The example below is a $100 bonus with a 40× wagering requirement, cleared on slots with a 96% RTP and a $5 maximum bet. Change any field and the result updates straight away.
How the calculator works
The maths behind a wagering requirement is short:
- Wagering required = the amount the requirement applies to × the multiplier. A 40× requirement on a $100 bonus means $4,000 of bets.
- Bets you place = wagering required ÷ game contribution. If a game counts 10% towards the requirement, every $10 you bet clears only $1.
- Average cost of clearing = bets you place × house edge, where the house edge is 100% minus the game's RTP. At 96% RTP the house keeps $4 of every $100 bet on average.
- Average bonus value = bonus − average cost of clearing. A positive number means the bonus is worth more than the play needed to unlock it, on average. A negative number means the requirement costs more than the bonus pays.
The result is an average over a very large number of players. A single session swings far above or below it, and the calculator does not model the chance of losing your whole balance before you finish, a cap on what you can cash out, or games the terms exclude.
What each field means
- Deposit. The amount you pay in to claim the offer.
- Bonus amount. The bonus money you receive. For a 100% match on a $100 deposit, that is $100; for a 150% match, $150.
- Wagering requirement. The multiplier in the terms, such as 10×, 35× or 40×.
- Wagering applies to. Some casinos count the bonus only, some the deposit only, and some the deposit and bonus together. The same multiplier on deposit + bonus doubles the betting needed for a 100% match.
- Game contribution. Slots usually count 100%. Table and live games often count 10–20% or nothing at all; the bonus terms list the rates.
- Game RTP. The return to player published for the game you plan to use. Our RTP and house edge guide explains what the figure can and cannot tell you.
- Maximum bet. Many bonuses cap the stake while a bonus is active. The calculator shows how many bets at that cap the requirement takes; leave it empty if there is no cap.
Worked examples
| Offer | Wagering required | Bets placed | Average cost at the stated RTP | Average bonus value |
|---|---|---|---|---|
| $100 bonus, 40× bonus only, slots at 96% RTP | $4,000 | $4,000 | $160 | −$60 |
| $150 bonus on a $100 deposit, 10× bonus only, slots at 96% RTP | $1,500 | $1,500 | $60 | +$90 |
| $100 bonus on a $100 deposit, 35× deposit + bonus, slots at 96% RTP | $7,000 | $7,000 | $280 | −$180 |
| $100 bonus, 40× bonus only, a table game at 99% RTP counting 10% | $4,000 | $40,000 | $400 | −$300 |
The second row matches the shape of BlockBet's welcome offer, a 150% match with 10× bonus wagering and a $5 maximum bet: at $5 a spin, $1,500 of wagering takes 300 bets. Its terms also cap what you can cash out from the bonus at 10× the bonus amount. The last row shows why low-contribution games rarely help: the higher RTP does not make up for betting ten times as much.
Offers that cost less to clear
The lower the multiplier, the more of a bonus you keep on average. Rakeback and cashback work differently: they return part of what you bet or lose, and usually come without a wagering requirement at all. Compare the current offers in our crypto casino bonuses ranking and the best rakeback and cashback casinos, and read the full rules on bonus balances in our guide to bonus terms, wagering and withdrawals.
Taking a bonus is always optional. If the requirement is high or the terms are unclear, playing without one keeps your balance free to withdraw.
Wagering calculator FAQ
What is a wagering requirement?
It is the amount you must bet before bonus money, and anything you win with it, can be withdrawn. It is written as a multiplier: 40× on a $100 bonus means $4,000 of eligible bets.
How do I calculate a wagering requirement?
Multiply the amount the requirement applies to by the multiplier, then divide by the game's contribution rate. A $100 bonus at 40× needs $4,000 of bets on slots that count 100%, or $40,000 on a game that counts 10%.
Is a 35× wagering requirement good?
On a slot with 96% RTP, 35× on the bonus costs about 1.4 times the bonus amount on average, so the bonus has a negative average value. Requirements of around 10× or lower usually leave a positive average value. Run the exact terms through the calculator to see the numbers.
Does wagering apply to my deposit too?
It depends on the casino. Some count only the bonus, some only the deposit and some the deposit and bonus together. The bonus terms say which, and the difference can double the betting needed.
Why do table games count less towards wagering?
Games such as blackjack and baccarat have a low house edge, so casinos reduce their contribution, often to 10–20%, or exclude them. Slots usually count in full.
Does a positive bonus value mean I will make a profit?
No. It is an average across many players. Any one player can lose the deposit and the bonus before finishing the requirement. Set a budget you can afford to lose and see our responsible gambling guide for tools and free help.
