Wagering Calculator
Casino bonuses look generous until you account for wagering. This calculator shows the real turnover a bonus demands and whether it's +EV before you claim it. See our no-deposit bonus list and casino reviews for bonuses worth your time. 18+.

How it works
Required turnover = base × multiplier ÷ weighting. Expected cost = turnover × (1 − RTP). Net expected value = bonus − expected cost. A positive EV means the bonus is, on average, worth claiming; negative means it likely costs you money.
Worked example
A €100 bonus, 35× wagering on the bonus only, 96% RTP slots, 100% weighting: turnover = 100 × 35 = €3,500; expected cost = 3,500 × 0.04 = €140; net EV = 100 − 140 = −€40 → Avoid. The same bonus at 20× flips to +€30 (worth it).
Wagering calculator FAQ
How is wagering (playthrough) calculated?
Required turnover = the base amount (bonus, or deposit + bonus) × the wagering multiplier, divided by the game's weighting. A €100 bonus at 35× on 100%-weighted games means €3,500 of bets before you can withdraw.
What does the expected cost mean?
Every bet returns slightly less than it stakes (1 − RTP). Expected cost = required turnover × (1 − RTP). At 96% RTP, €3,500 of turnover costs about €140 in expected losses — which can exceed the bonus itself.
What's a good wagering requirement?
Lower is better. 35× or under is reasonable; 60×+ is predatory. Game weighting matters too — if table games count 10%, your real turnover requirement is 10× higher.
