Casino bonus value calculator
Enter the offer as its terms state it. The calculator gives the total you must stake, what that costs on average, and, for even-money bets, the exact chance of finishing the wagering before your balance runs out.
How it works
- Total to stake = the wagering multiple × the bonus (or deposit plus bonus), divided by the share of each stake your game counts.
- Average cost if fully staked = total to stake × the house edge. It is the worst case: players who go bust stop staking, and lose only their balance.
- Chance to finish and average cash out are exact for even-money bets, such as red or black at roulette: the balance, counted in stakes, moves up or down by one each bet, and every possible path is added up. Slots swing far more than even-money bets, so fewer players finish; their average result lies between the worst case and the bonus.
