The balance that is not your money yet
You make a deposit, accept a promotion, and the cashier now shows two numbers: a cash balance and a bonus balance. They look identical, but they are governed by different rules. Cash can be withdrawn once any deposit conditions are satisfied. Bonus funds are a conditional credit. They exist inside the account, they can often be used to place wagers, but they cannot leave the account until a set of attached conditions has been completed.
Most confusion about bonus funds comes from treating them as money that has already arrived. It is more accurate to treat them as a wagering obligation with a potential payout at the end. The promotion's terms define the path from credit to withdrawable cash, and every step of that path changes the real value of the offer.
Where the value of a bonus is decided
When a sportsbook or casino advertises a bonus, the headline figure is the least informative number in the offer. The value is constructed from four separate conditions that work together: the wagering requirement, game weighting, the maximum cashout cap, and the expiry window. A large bonus with a heavy requirement can be worth less than a small bonus with a light one.
| Condition | What it controls | Why it matters |
|---|---|---|
| Wagering requirement | How much must be wagered before bonus funds convert | Sets the total volume of play you must generate |
| Game weighting | How much each wager counts toward the requirement | Determines which games can realistically clear the bonus |
| Maximum cashout cap | The ceiling on what can be withdrawn from bonus winnings | Limits the upside even after the requirement is met |
| Expiry window | How long the requirement must be completed within | Creates a time pressure that can force faster, larger wagers |
Each of these is stated in the promotion's terms. The terms page is the only place where the numbers that apply to your specific offer exist, and you should read it before opting in, not after the bonus has been credited.
Wagering requirements as a multiplier
A wagering requirement, also called playthrough, is a multiplier applied to the bonus amount, and sometimes to the deposit plus bonus. It states how much must be wagered before bonus-related funds can be withdrawn. The arithmetic is simple, but the framing matters. As an example, a 30x requirement on a 50-unit bonus means 1,500 units must be wagered before the bonus funds can be withdrawn. If the requirement applies to deposit plus bonus instead of bonus only, the total is higher.
This is not a fee of 1,500 units. It is a volume of turnover. You might wager 100 units, win back 90, wager those 90, win back 80, and so on. The requirement counts total wagers placed, not total losses. But because every wager on a negative-expectation game carries a built-in house edge, the expected cost of generating that turnover is the house edge multiplied by the total amount wagered. The bonus is worth something only when its value exceeds the expected loss from clearing it.
Game weighting and the games that do not count
Not every wager counts equally toward the requirement. Operators assign a weighting percentage to different game categories. A slot wager might count at 100%, meaning every unit wagered counts as one unit toward the requirement. A table game wager might count at a much lower percentage, and some games might be excluded entirely. This matters because the house edge and the speed of play differ across games. A low-weighting game forces more total wagers to clear the same requirement.
The weighting table is part of the promotion's terms. Before you accept a bonus, find the list of excluded games and the weighting percentages. If the games you intended to play are excluded or heavily discounted, the bonus is not what the headline suggested.
Cashout caps and the ceiling on winnings
Even after the wagering requirement is complete, the maximum cashout cap sets an upper limit on how much of the bonus-derived winnings can be withdrawn. If the cap is low relative to the bonus size, the offer is effectively a small fixed-value credit with extra steps. Any winnings above the cap are removed from the account when the withdrawal is processed.
The cap is a hard ceiling, not a target. It does not change the house edge on the games you play, and it does not make reaching the cap more or less likely. It simply limits what the bonus can become. A player who reads only the bonus amount and the wagering requirement is evaluating two thirds of the offer.
Expiry windows and the pressure to play faster
Bonus funds come with a deadline. The wagering requirement must be completed within a set number of days, or the bonus and any winnings derived from it are removed. The expiry window is not a neutral detail. It interacts with the wagering requirement to determine the pace of play needed to clear the bonus.
A short expiry window on a large requirement forces a high volume of wagers per day. Because the house edge applies to every wager, a faster pace means the expected loss accumulates more quickly. The expiry window is one of the main reasons a bonus that looks generous on paper can be expensive to clear in practice.
Bonus funds in the cashier
On most sportsbook apps, the cashier displays the cash balance and the bonus balance separately. When you place a wager, the system draws from cash first, then from bonus funds, unless the terms specify a different order. Some promotions restrict bonus funds to specific markets or minimum odds. A wager placed with bonus funds that does not meet the odds requirement may not count toward the playthrough at all.
Before you place the first wager with a bonus balance, check three things in the terms: which markets or games the bonus can be used on, whether there is a minimum odds threshold, and whether the wagering requirement is calculated on the stake or on the winnings. Each of these changes how the bonus behaves in practice.
Loyalty value is a different calculation
Bonus funds are a front-end promotion. Loyalty and comp programmes are a back-end system that rewards tracked play. The two are often confused because both appear as credits in the account. But a loyalty programme does not give you a fixed credit with a wagering requirement. It awards value based on the theoretical loss your play is expected to generate.
Theoretical loss is a calculation, not a prediction of what you will lose in a session. It is built from three inputs: your average bet size, the number of decisions or wagers you make per hour, and the house edge on the games you play. As an example, suppose a player wagers an average of 10 units per decision, makes 60 decisions per hour, and plays a game with a 2% house edge. The theoretical loss is 10 multiplied by 60 multiplied by 0.02, which is 12 units per hour. That figure is the expected long-run cost of the play, not a bill presented at the end of the hour.
Loyalty programmes use this calculation to decide how much to give back in the form of points, comps or tier progress. The giveback is always a fraction of the theoretical loss, because the operator's margin must cover the cost of the games and the business. A loyalty programme is not a way to earn money. It is a rebate on expected loss.
Reading the terms before opting in
Every condition described here is stated in the promotion's terms and conditions. The terms page is not fine print to skip. It is the specification of the offer. Before you accept a bonus, open the terms and find the following: the wagering requirement and whether it applies to bonus only or deposit plus bonus, the game weighting table, the maximum cashout cap, the expiry window, and the list of excluded games or markets. If any of these is missing or unclear, the support channel for the operator is the place to ask before you opt in.
A bonus that cannot be cleared within the expiry window on games you play is not a bonus. It is a liability with a deadline.
FAQ
Can I withdraw bonus funds immediately?
No. Bonus funds are a conditional credit. They can only be withdrawn after the wagering requirement is completed, the game weighting conditions are satisfied, and any maximum cashout cap is applied. The cash balance and the bonus balance are governed by different rules, and the cashier displays them separately for that reason.
Why did my bonus winnings disappear after I met the requirement?
The most common reason is the maximum cashout cap. If your bonus-derived winnings exceeded the cap stated in the terms, the excess is removed when the withdrawal is processed. Another possibility is that the wagering requirement was not completed because some wagers did not count toward it, due to game exclusions or minimum odds thresholds.
Do loyalty points work the same way as bonus funds?
No. Loyalty points are earned from tracked play and are calculated from theoretical loss, which is average bet times decisions per hour times house edge. Bonus funds are a fixed promotional credit with a wagering requirement. Loyalty value is a rebate on expected loss, while bonus funds are a conditional credit that must be cleared before withdrawal.
