The maths, in plain words
Bonus
Deposit times the match percentage, up to the cap.
Rollover
Wagering times the bonus (or deposit plus bonus), divided by how much your game counts.
Expected cost
Rollover times the house edge. That is what the casino keeps on average while you clear it.
Value
Bonus minus expected cost. Above zero, the bonus pays on average. Below, you are better off without it.
Questions about this tool
Why is a big bonus often worth less than nothing?
Because the casino keeps a share of every bet you make while clearing the wagering. With 40x on the bonus and a 4% house edge, you pay 1.6 times the bonus on average to unlock it.
Which games clear a bonus cheapest?
Games with a low house edge that still count 100% toward wagering. That is rare: most casinos count blackjack and live games at 10 to 20%, which makes the rollover five to ten times longer.
