A "200% up to 1 BTC" headline is marketing. What matters is how much you have to bet to unlock it and how much that betting costs you on average. Type the terms in, get the honest number out.

The formula
Total to wager = (bonus, or bonus + deposit) × multiplier ÷ contribution. A 10% contribution means you need ten times the raw turnover.
Expected loss = total to wager × (1 − RTP). This is the house edge applied to every bet you are forced to make.
Bonus EV = bonus − expected loss. Above zero the bonus is worth something on average; below zero you are paying for the privilege. The verdict threshold is exactly EV > 0, and I do not adjust it for variance, caps or your sanity.
Bets at max bet = total to wager ÷ max bet. A rough count of how long you will be grinding.
Wagering FAQ
What is a wagering requirement?
The total amount you must bet before bonus money (and often the deposit) becomes withdrawable. "40x bonus" on a $100 bonus means $4,000 of bets. "40x bonus + deposit" on $100 + $100 means $8,000.
Why does game contribution matter so much?
If table games count 10%, every $1 bet on blackjack clears only $0.10 of wagering, so you effectively need ten times the turnover. That is why "bonus abuse" rules push you onto slots, which also have lower RTP.
Is a positive EV a guaranteed profit?
No. It is the average over many attempts. Variance is huge and max-bet rules, excluded games and max-cashout caps can quietly turn a positive EV into a negative one. Read the terms, then use this tool again.
