How the casino bonus calculator works
The casino bonus calculator helps you work out how much a deposit bonus really requires of you and how large the bonus’s effective value is after wagering.
A bonus headline often promises a big amount, but the real value depends on the wagering requirement, the bet contribution and the game’s return percentage, i.e. the RTP. The calculator brings these factors together in one place.
What is the wagering requirement?
The wagering requirement tells you how many times you must wager the bonus amount before you can withdraw a win as real money. The formula is simple:
Formula
Wagering amount = bonus amount × wagering multiplier
Example: a 100% welcome bonus
Suppose you deposit €100 and get a 100% bonus up to €200, with a 35× wagering requirement.
- Bonus given€100
- Required turnover€100 × 35 = €3,500
- Theoretical loss (96% RTP)€3,500 × 4% = €140
This means the effective value of a €100 bonus after the loss can be zero or negative — especially if the bet contribution is below 100%.
Why the bet contribution matters
Not all games count equally towards wagering. Slots usually give 100%, table games often 10% or less. With a low bet contribution the real required turnover grows by multiples, so it’s worth checking before you play.
Tips before depositing
- Always compare the wagering multiplier, not just the bonus percentage.
- Check whether the requirement is on the bonus (b) or on bonus plus deposit (d+b).
- For a more precise estimate, also use the other calculators and the offer value comparison.
- All results are theoretical decision aids, not guaranteed wins.
Frequently asked questions
Does a high bonus percentage always mean a good offer?
No. A 200% bonus with 50× wagering can be worse than a 100% bonus with a 25× requirement. What matters is the wagering amount and bet contribution, not the headline percentage.
How do you calculate bonus wagering?
Multiply the bonus amount by the wagering multiplier. For example, a €100 bonus with a 35× requirement means €100 × 35 = €3,500 of required turnover.
What is a bonus’s effective value?
It’s the amount that remains from a bonus on average after the RTP loss during wagering. With a low RTP and a high requirement the effective value can be zero.
