Calculate the true expected value of any casino bonus after accounting for wagering requirements, max bets, and game restrictions.

Enter the casino bonus details: the bonus amount, wagering requirement multiplier, maximum allowed bet while the bonus is active, the RTP of your preferred game, the game's contribution percentage, and any maximum withdrawal cap. Click Calculate to see the true expected value (EV) of the bonus.
A £100 bonus with 35x wagering sounds generous, but the true value depends on many factors. A low RTP game or strict max-bet rule can turn a seemingly profitable offer into a guaranteed loss. The max bet restriction is particularly important — if it forces you to bet at £5 or less, it extends your play time and total variance exposure significantly.
Withdrawal caps can also gut a bonus's value. A cap of £100 on a £100 bonus means any winnings above that are forfeit — effectively capping your upside while you still bear all the downside risk of the wagering requirement. Use this calculator to compare offers across casinos and find the best real-money value.
