Doing the Arithmetic on a Wagering Requirement
A bonus is worth what is left after the conditions. Three numbers settle it, and the sum takes a minute.
Step one: how much has to be bet
A wagering requirement says how many times the bonus must be staked before any of it can be withdrawn. The total is simply bonus times multiple.
Take a real published example from the Taiwanese market. The information site 夜色娛樂城 lists a NT$368 trial credit that carries a 30x wagering requirement and a withdrawal cap of NT$1,500. Thirty times 368 is NT$11,040 in total bets before a withdrawal is possible.
Step two: what that turnover is expected to cost
Every bet has an expected cost equal to the stake times the house edge. On a game with a 4% edge, NT$11,040 of turnover has an expected cost of about NT$442. That is more than the NT$368 credit, so on average the credit runs out before the requirement is met. On a game with a 1% edge the expected cost is about NT$110, and something is likely to be left.
This is why the list of eligible games matters as much as the multiple. If only high-edge games count, the same headline offer is worth far less.
Step three: the ceiling
A withdrawal cap puts a limit on the best case. With a cap of NT$1,500, a lucky run that turns the credit into NT$10,000 still pays NT$1,500. The cap does not change the average much, but it removes the tail that makes long-shot play attractive.
A quick checklist
- Bonus amount, wagering multiple, and whether the multiple applies to the bonus alone or to deposit plus bonus.
- Which games count, and at what percentage.
- Maximum withdrawal, maximum bet while the bonus is active, and the time limit.
If any of those is missing from the page, ask before depositing. Terms that are hard to find are part of the answer.
