What is Wagering in Casino and How to Calculate It — Simple Explanation
Wagering x40 is not a gift, it is a task. We explain how to calculate the real cost of a bonus and when it is better to play without one.
What wagering really means
A casino offers you a $100 bonus with ×40 wagering. Sounds like a gift? Here's what it actually means: you have to place $4,000 in bets ($100 × 40) before you can withdraw any of the bonus money.
At an average slot RTP of 96%, statistically you'll lose $160 across $4,000 in bets. So a $100 bonus with ×40 wagering actually costs you $60 over the long run.
How to calculate the real value of a bonus
| Bonus | Wagering | Required bets | Loss (RTP 96%) | Real value |
| $100 | ×20 | $2,000 | −$80 | +$20 |
| $100 | ×30 | $3,000 | −$120 | −$20 |
| $100 | ×40 | $4,000 | −$160 | −$60 |
| $100 | ×60 | $6,000 | −$240 | −$140 |
Takeaway: a bonus with wagering above ×25 on slots with a 96% RTP is mathematically a losing deal. You give up more than you get.
When a bonus is worth taking
- Wagering of ×20 or lower
- A clearing window of 30 days (not 72 hours)
- No cap on the withdrawal of bonus winnings
- High-RTP slots count toward the wagering
When it's better to play without a bonus
If wagering is ×40 or above — play with your own money. You can withdraw your winnings at any moment, with no strings attached. Sometimes the best bonus is no bonus at all.
