How wagering requirements turn a big bonus into a small one
The short answer
A 200% bonus at 40x wagering can be worth less than nothing. Here is the arithmetic that decides it, and why no-wagering rakeback usually wins.

A wagering requirement is the multiplier a casino applies to a bonus before the money becomes yours. At 40×, a $200 bonus has to be wagered $8,000 before any of it can be withdrawn. That single number does more to determine what a bonus is worth than the headline percentage does, and it is the reason two offers that look ten times apart in the advert can be worth roughly the same amount.
The cost of turnover
Every wager you place to clear a requirement passes through a game that returns slightly less than it takes. That gap is the house edge — one minus the RTP. At 96% RTP the edge is 4%, so every $100 of turnover has an expected cost of $4.
Put the two together and the expected net value of a deposit bonus is:
net = bonus − (bonus × wagering × houseEdge)For a $200 bonus at 40× on 96% RTP games, that is $200 − ($200 × 40 × 0.04), which is $200 − $320 — a net expected loss of $120. The bonus costs more to clear than it pays out. This is not a trick specific to any operator; it falls straight out of the arithmetic whenever the wagering multiplier exceeds the reciprocal of the house edge.
Where the break-even sits
The break-even multiplier is 1 ÷ houseEdge. On 96% RTP games that is 25×, and on 96.8% games — the highest average we track — it is about 31×. Above that multiplier, a deposit bonus has negative expected value no matter how large the percentage attached to it is.
This is why the 40× requirements common in this vertical matter so much more than the percentage beside them, and why our best-bonuses ranking orders offers by structure rather than by headline number.
Why rakeback breaks the pattern
Set the multiplier to zero and the entire cost term disappears. Rakeback returns a share of the house edge on wagers you were making anyway, with no turnover condition attached, so its expected net value is simply its face value.
That is the structural reason a 15% rakeback with no wagering can beat a 200% match at 40×, despite advertising a number more than ten times smaller. You can check any specific pair of terms in the bonus calculator.
What to check before depositing
The percentage is the least informative number in a bonus offer. Before depositing, find the wagering multiplier, whether it applies to the bonus alone or to bonus plus deposit, the game weighting, and the expiry window. Any one of those can turn a positive-looking offer negative, and all four are usually a click or two further into the terms than the percentage is.
