Enter the deposit match terms to see the wagering you need to do and what the bonus is likely to be worth.
If the game contributes less than 100%, you have to stake more to clear the same wagering, which raises the expected loss. A negative value means you are likely to lose more completing the wagering than the bonus is worth. Since 19 January 2026, UK-licensed sites cannot set wagering above 10x.

How to use the casino bonus value calculator
A deposit match can be worth a lot, or very little, depending on the wagering. This calculator estimates the bonus value after the cost of clearing the wagering. For the basics, read how casino bonuses work.
1. Deposit and match. Enter what you plan to deposit, the match percentage and the maximum bonus.
2. Wagering. Enter the multiple and whether it applies to the bonus only or to deposit plus bonus. Since 19 January 2026, UK-licensed sites cannot set wagering above 10x.
3. Game RTP and contribution. Slots usually count 100%. Table games often count 10–20% or not at all, which makes wagering far more expensive.
How the estimate works
The calculator multiplies the total you must stake by the house edge (100% minus RTP) to get the expected loss while wagering. It then subtracts that from the bonus. For example, a £20 bonus with 10x wagering on 96% RTP slots means £200 of wagering, an expected loss of £8 and an estimated value of £12.
