Wagering requirements explained (with real math)
Wagering requirements set how many times a bonus, sometimes the deposit too, must be staked before it can be withdrawn, for example $100 x 35 = $3,500 in bets; the maths, expected loss and a calculator follow.
How wagering requirements work
Wagering requirements are play-through conditions attached to casino bonuses. They say how much qualifying betting must happen before bonus funds, and often winnings made from those funds, become withdrawable cash.
Your own deposited money and the bonus may sit in separate balances, or they may appear together in the account view while the terms still treat them differently. The terms decide which balance is used first, which games count, and what happens to the bonus if you ask for a withdrawal early.
A settled qualifying bet normally counts towards the requirement. If the bet wins, the returned stake and win stay in the account subject to the bonus terms. If it loses, your balance falls, but the settled stake may still count as progress.
The UK Gambling Commission gives a simple example, a £10 bonus at 50x means £500 of play-through before withdrawal, and its Great Britain rules also require bonus terms to be clear, transparent, fair and readily accessible.
The same formula applies in dollars: bonus base multiplied by the wagering multiple. This is not free money. The requirement forces you to keep playing, and casino games still carry a house edge while you clear it.
A bonus can therefore increase the amount of play you can attempt, but it does not remove the underlying cost of the games. The key question is not whether the offer looks large. The key question is how much turnover it forces and whether the remaining terms make that turnover realistic.
How to calculate wagering
Start with the amount the terms apply to, then multiply it by the wagering multiple. If games do not contribute in full, adjust the turnover upwards. If the terms are unclear about the base, do not assume the lighter version applies.
Bonus only
Bonus-only wagering uses only the promotional money as the base. With a $100 bonus at 35x, the turnover required is $3,500. If every permitted game counts in full, each qualifying stake reduces the remaining requirement by the stake amount. Winning bets do not remove the remaining requirement.
They only keep the balance alive while the turnover continues. This is why a player can be ahead during bonus play but still unable to withdraw. The account balance and the cleared wagering balance are different things until the promotion has finished.
Deposit plus bonus
Deposit plus bonus wagering uses both your cash deposit and the bonus as the base. With a $100 deposit and a $100 bonus at 35x on deposit plus bonus, the turnover required is $7,000. The same headline multiple is therefore much heavier than a bonus-only term.
It also exposes more of your own money to normal casino variance. This structure is easy to underestimate because the advertised multiple looks familiar. The calculation must always start with the exact base named in the terms.
Free spins winnings
Free spins can have no wagering on the spins themselves but wagering on any winnings from them. If free spins produce $20 and those winnings carry 40x wagering, the turnover required is $800.
The free spins label is less important than the rule applied to the winnings after the spins are complete. No-deposit spins and cashable no-deposit offers can still have withdrawal conditions. If an advert says no wagering, still check whether cashout limits, game restrictions or expiry clauses apply.
Expected loss while clearing a bonus
Expected loss is required turnover multiplied by the house edge. In these examples, a 96% RTP game is treated as a 4% house edge game. RTP is a long-run average, not a session promise.
Losing often while trying to clear a bonus is not unusual, because the play needed to clear it is still gambling with a negative average return. A bonus does not change the game maths. It changes the starting balance and the conditions attached to withdrawing that balance.
A $100 bonus at 35x bonus-only wagering requires $3,500 of turnover. On a 96% RTP game, the expected loss while clearing it is $140.
A $100 deposit plus a $100 bonus at 35x on deposit plus bonus requires $7,000 of turnover, with an expected loss of $280 on the same RTP. The bonus expected value is the bonus amount minus expected loss.
On 96% RTP slots, a $100 bonus at 35x bonus-only wagering has an expected value of -$40, while a $100 bonus at 10x has an expected value of $60. For the wider concept, see expected value in gambling and how RTP works.
The house edge is not the same on every permitted game. European roulette carries a 2.70% house edge. In 8-deck baccarat, the Banker bet carries a 1.06% house edge and the Player bet 1.24%.
Those figures can look attractive beside many slot examples, but the bonus terms may reduce table-game contribution or exclude the game entirely. That means a lower house edge does not automatically mean easier clearance. The practical cost depends on turnover, game contribution and the chance that the balance survives long enough to complete the required play.
Average loss is not the same as bust risk. A bonus can be mathematically close to break-even and still fail often because the balance runs out before the wagering is complete. Higher variance makes this more visible.
A balance can swing up early, then fall before the remaining turnover reaches zero. The simulation table below uses a 96% RTP slot model with $1 spins. It shows why the multiple matters even when the game RTP stays the same.
Bonus | Attempts that finish with money left | Average cashable balance |
|---|---|---|
$100 bonus at 35x | 15.6% | $52 |
$100 bonus at 10x | 39.5% | $74 |
Game contribution rates
Game contribution decides how much each stake reduces the remaining wagering total. Slots usually count in full, while table games and live dealer games often count little or nothing. The reason is simple: the operator does not treat every game as equally useful for clearing a promotion.
Kansspelautoriteit requires Dutch bonus terms to state the wagering requirement and the bonus expiry date. For game weighting, terms should also make clear which games are eligible, excluded or reduced. If a game is not listed clearly, treat that as a risk rather than an invitation to guess.
The effect can be severe. If you have $3,500 of wagering left and play a game that contributes 10%, the actual turnover needed to clear it is $35,000. At 20% contribution, the turnover needed is $17,500.
A low-edge game can therefore be poor for bonus clearing if it barely contributes. The opposite can also happen: a higher-edge game may contribute in full but create a larger expected loss per dollar staked. The best calculation uses both parts together.
First work out how much real turnover the contribution rate creates. Then apply the expected loss of the game to that turnover. Read the game weighting and max bet rules before choosing a game.
Other bonus terms that change the maths
The wagering multiple is only the first filter. Several other clauses can turn a bonus that looks reasonable into one that is impractical, especially if they limit bet size, cashout or game choice.
These terms matter because they affect how much freedom you have while clearing the bonus. A low multiple with strict restrictions may be worse than a higher multiple with clearer, more flexible terms. Read the full promotion rules before opting in, not after a withdrawal is delayed.
- Maximum bet: A bonus can set a highest permitted stake while wagering is active. Breaking it can void the bonus or related winnings. The rule may apply even if a larger stake was accepted by the software.
- Time limit: A bonus can expire before you finish the turnover. A shorter deadline pushes players towards faster or larger betting, which increases risk. If you would not normally play enough to clear the turnover before expiry, the offer is probably a poor fit.
- Maximum cashout: Some bonuses cap how much can be withdrawn from bonus play. A high balance above the cap may be removed when the bonus closes. This can reduce the upside while leaving the downside unchanged.
- Excluded payment methods: Some deposit methods may make a bonus unavailable, or may not count for a promotion. This can matter if the bonus is linked to a specific deposit route or if withdrawal options depend on the deposit method.
- Sticky and non-sticky bonuses: A sticky bonus is not withdrawn with cash winnings. A non-sticky bonus can usually be removed from the balance under the terms, which may let you stop bonus play earlier. The difference changes how much of the displayed balance is really yours.

Typical wagering by bonus type
The same bonus label can hide very different rules. Compare the actual terms before treating any casino bonus as good value. A welcome offer, reload offer, free spins package or no-wagering bonus can all be fair or poor depending on the base amount, game contribution, expiry, cashout rules and withdrawal conditions. The label is marketing. The terms are the contract.
Bonus type | How the wagering usually works |
|---|---|
Welcome bonus | Often applies to the bonus amount. Some terms apply it to the deposit plus the bonus, which makes the turnover heavier. Check whether the bonus is released immediately or only after qualifying play. |
Reload bonus | Usually works like a smaller repeat deposit bonus, with game eligibility, expiry and maximum bet clauses. The same calculation applies, but the value may be lower if the terms are tighter. |
Free spins | Often applies wagering to winnings from the spins rather than to the spins themselves. Check which slot is eligible and whether winnings are capped before they become cashable. |
Cashback | May be paid as withdrawable cash or as bonus funds with play-through. The exact treatment depends on the licence and terms. In the Netherlands, Kansspelautoriteit says cashback bonuses that return part of a player’s loss are not allowed. |
No-wagering bonus | Removes the play-through requirement, but may still have cashout, expiry, game or payment restrictions. A deposit bonus with no wagering requirements is simpler, but it still needs readable rules. |
Wagering rules by country
Bonus rules depend on the licence, not the marketing text. In Germany, the Gemeinsame Glücksspielbehörde der Länder says adverts with bonuses and discounts must clearly state who benefits, the reason, the duration and the value of the discount. The same source also shows why promotional clarity matters: a bonus should be understandable before a player takes it, not explained only after a dispute.
Country | Rule |
|---|---|
United Kingdom | The UK Gambling Commission caps bonus wagering at 10x bonus funds from 19 January 2026 and requires licensees not to include more than one gambling product type in a single incentive. |
Netherlands | Kansspelautoriteit says online gambling bonuses may not be aimed at young adults under 24, bonus terms must state the wagering requirement and expiry date, an operator may only grant a bonus if the player expressly accepted the bonus terms, and operators may not offer a bonus during participation in the game. |
Spain | The Boletín Oficial del Estado records that Spain’s former ban on new-customer acquisition promotions was annulled by the Supreme Court judgment of 2 April 2024; Spanish promotion advertising must disclose the wagering amount, the number of times a stake must be wagered where applicable, and the maximum release period, while players who receive an increase in deposit limits may not receive personalised promotions for the following 30 days. |
Rules change, so check the regulator and current terms for the licence that covers your account.
When a bonus is worth taking
A bonus is worth considering only if the expected cost and restrictions still leave value for the way you already planned to play. That is different from finding a system to beat it. No staking pattern changes the house edge or makes a losing game mathematically favourable by itself.
The cleanest approach is to calculate the turnover first, then ask whether you would still play those games, at that pace, without the promotion. If the answer is no, the bonus is driving extra gambling rather than reducing the cost of gambling you had already chosen.
- The multiple: A lower multiple means less turnover before withdrawal. It also gives variance less time to drain the balance before the requirement is complete.
- Contribution of the games you play: A game that contributes little can make the real turnover much higher than the headline term suggests. Do not compare offers until contribution is included.
- RTP of those games: Lower RTP means higher expected loss for the same amount of wagering. RTP still does not predict a single session result.
- Maximum cashout: A cap can remove much of the upside from a strong run. This matters most where the bonus balance is small but the required turnover is large.
- Time limit: A short expiry can push you into faster play than your budget allows. A bonus that needs rushed play is a warning sign.
Decline the bonus if clearing it requires bets you would not otherwise make, if the rules are unclear, or if the turnover conflicts with your budget. Set boundaries before playing with deposit and loss limits.
Common wagering mistakes
Most bonus problems come from treating the headline offer as the whole deal. The clauses below are the ones that most often change the result after play has already started.
They also explain why a player may feel that a bonus was won, then later find that the withdrawable balance is smaller than expected. The account screen is not enough. The promotion rules decide what counts, what is excluded and what can be cashed out.
- Breaking the maximum bet rule: A single oversized stake can breach the terms while the bonus is active. If the rules say a stake is too high, the fact that the game accepted the bet may not protect the bonus winnings.
- Withdrawing before the requirement is met: The withdrawal can cancel the bonus or remove winnings linked to uncleared bonus funds, depending on the terms. If your own money and bonus money are mixed, check how the operator separates them for withdrawal.
- Playing excluded games: Excluded games may add no progress, and in stricter terms they may void bonus winnings. This includes games that look available in the lobby but do not qualify for that promotion.
What this means before you accept a bonus
Treat wagering as the price of a promotion, not as a route to guaranteed profit. If the turnover, game restrictions and expected loss make the offer uncomfortable, skip it.
If gambling starts to feel like a way to repair losses, stop and use independent support such as gambling helplines by country. If a game feels due after losses, read why that thinking fails in common gambling myths.
Frequently asked questions
What does 35x wagering mean?
It means the qualifying amount must be staked 35 times before the bonus-linked balance can be withdrawn. The qualifying amount may be the bonus only, or the deposit plus the bonus, depending on the terms.
Do wagering requirements apply to the deposit?
Sometimes. Some offers apply the multiple only to bonus funds, while others apply it to both the deposit and the bonus. Deposit plus bonus terms create much higher turnover than bonus-only terms with the same multiple.
What happens if I withdraw before meeting wagering?
The casino may reject the withdrawal, cancel the bonus or remove winnings linked to uncleared bonus funds, depending on the terms. Check whether your real-money balance remains withdrawable under the rules that apply to the licence and promotion.
Are no-wagering bonuses really better?
They remove the play-through requirement, which is a real advantage. They can still have maximum cashout rules, expiry, game restrictions or payment exclusions, so the no-wagering label is not enough by itself.
