Bonus value calculator
Enter a bonus offer and pick a game — we simulate thousands of playthroughs to show what it's really worth.
A negative expected value means the bonus costs you money on average; the clear % is your chance of finishing the wagering before running out.
How wagering requirements work
If a €100 bonus has 35x wagering, you must bet €3,500 before withdrawing. Game contribution and RTP decide how much that really costs you.
Why most bonuses are negative value
High wagering, low game contribution and a max cashout all erode a bonus. The calculator prices all of that in.
How games count toward wagering
Typical contribution rates — always confirm in your bonus terms.

Bonus types explained
- Cashable: You can withdraw the bonus and winnings after wagering.
- Sticky: The bonus itself can't be withdrawn — only winnings above it.
- Free spins: Spins on set games; winnings usually carry their own wagering.
- Cashback: A percentage of losses returned, often with light or no wagering.
Worked example
A 100% up to €500 bonus at 35x on a 96% RTP slot: you must wager €3,500, expect to lose about 4% of turnover, and clear it roughly half the time.
