How We Value a Casino Bonus
A headline like "200% up to £500" tells you almost nothing about what an offer is actually worth. The number that matters is the expected value once wagering requirements, game contribution rates, max-bet rules and time limits are applied. We work that out before recommending anything, and you can run the same maths on any offer with our bonus calculator. The formula and the assumptions behind it are documented in our bonus EV methodology.
The five main bonus types, from best to worst value
- No-wagering offers. Winnings are paid as withdrawable cash with no playthrough attached. The headline amounts are usually smaller, but what you win is yours. We track which operators offer these in our guide to no-wagering casinos.
- Cashback. A percentage of net losses returned, ideally as cash. Check whether the cashback itself carries wagering; if it does, the deal is weaker than it looks.
- Welcome match bonuses. The biggest headlines and the most strings. A typical 35x requirement on a £100 bonus means £3,500 of turnover before you can withdraw a penny.
- Free spins. Value depends on the spin stake and the attached game. Fifty spins at 10p is £5 of stake value, often with wagering applied to any winnings on top.
- VIP and loyalty programs. Genuine value for high-volume regulars through rakeback and reloads; close to irrelevant for casual players.
Why expected value beats headline numbers
Wagering is not a formality, it is a cost. Clearing £3,500 of turnover on slots with a 96% RTP costs roughly £140 in expected losses, which is more than the £100 bonus is worth. That is why some of the biggest offers on the market are net-negative, and why a modest low-wagering deal can beat a flashy one. Our reviews score every bonus this way instead of repeating the marketing figure.
One caveat applies to everything above: a bonus is a discount on play you were going to do anyway, never a reason to deposit more. If an offer tempts you past your budget, skip it. Our responsible gambling page covers deposit limits and self-exclusion tools.
