Wagering Requirements: The One Calculation That Decides Whether a Bonus Is Worth Taking
One line of arithmetic settles almost every bonus offer in both directions, and the three terms that modify it are all published. Here is the line, and here are the three.

A wagering requirement specifies how many times the bonus amount must be staked before anything derived from it can be withdrawn. A $500 bonus at 35x means $17,500 of turnover.
That much is usually understood. What is less often done is the next step, which converts the requirement into a cost — and the whole subject reduces to that one line.
The line
Expected cost of a bonus = bonus × wagering multiple × house edge.
Turnover has a cost because every unit staked passes through the game's edge. A bonus is worth taking when the amount received exceeds that cost, and not otherwise.
| Bonus | Wagering | Turnover | Cost at 4% edge | Net |
|---|---|---|---|---|
| $100 | 20x | $2,000 | $80 | +$20 |
| $100 | 25x | $2,500 | $100 | Break-even |
| $100 | 35x | $3,500 | $140 | −$40 |
| $500 | 35x | $17,500 | $700 | −$200 |
The pattern is the whole subject. At a 4% edge, a wagering multiple above roughly 25x makes an offer negative before variance is even considered; below it, positive. The size of the bonus does not change that — only the multiple and the edge do.
The first modifier: game weighting
Not every dollar staked counts the same toward the requirement. Slots typically contribute 100%, table games far less, live tables often nothing.
A game contributing 20% requires five times the turnover to clear the same requirement — which multiplies the expected cost by five. That single term outweighs almost any difference in return figure between two games, and it is the reason a bonus cleared at a live table can be a completely different proposition from the same bonus on slots.
The weighting table is published with the offer. Reading it takes seconds and changes the answer more often than the headline multiple does.
The second modifier: maximum bet
Nearly every bonus carries a maximum stake for as long as wagering is outstanding, usually well below the normal table limit. Exceeding it once — including by accident, including on autoplay, which does not pause when a limit is crossed — is grounds for voiding the bonus and the winnings attached to it.
This is the single most common way a cleared bonus disappears at the withdrawal stage. It is not a technicality applied selectively; it is a stated term, and it is enforced.
The third modifier: the clock
Wagering requirements run for a fixed period. When the window closes, remaining bonus funds and everything won from them go with it, regardless of how close the requirement was to being met.
A $500 bonus at 35x needs $17,500 of turnover. At $1 per spin and 400 spins an hour, that is roughly 44 hours of play. Whether that fits inside a 30-day window is a question worth asking before accepting rather than on day 29.
The requirement people do not expect
Most terms also require the deposit itself to be wagered at least once, sometimes more, before the associated funds can be withdrawn — with no bonus involved at all.
The reason is regulatory rather than commercial: money in and straight back out without play is the textbook laundering pattern, and licensed operators are required to prevent it. The practical effect is that a deposit made by mistake cannot simply be reversed. Our terms page states the multiple that applies here.
A worked example, start to finish
An offer gives 100% up to $500 at 35x, slots weighted 100%, maximum bet $5, 30-day expiry, and you deposit $500.
- Bonus received: $500. Balance in play: $1,000.
- Turnover required: $500 × 35 = $17,500.
- Expected cost of that turnover at a 4% edge: $700.
- Expected value of the offer: $500 − $700 = −$200.
- On a 96% game the edge is 4%; on a 98% game it is 2%, and the cost falls to $350 — turning the same offer positive.
That final line is the useful one. The offer's value depends as much on which game you clear it on as on the offer itself, and the return figure is one tap away in the information panel.
Declining a bonus costs nothing at all. Accepting one you cannot clear inside its window can cost the winnings attached to it. Between those two facts sits every decision in this subject, and the arithmetic above resolves it in about fifteen seconds — considerably faster than the reasons people accept anyway.
The checklist
- Multiple × bonus = turnover required.
- Turnover × edge of the game you will actually play = expected cost.
- Compare that to the bonus. If the cost is higher, decline.
- Check the weighting — anything below 100% multiplies step one.
- Check the maximum bet and set your stake below it before the first spin.
- Check the expiry against how many hours the turnover actually needs.
Six steps, all from published numbers. Our bonuses page covers the offer types this applies to, and the payment route changes none of it.
