Expected loss is a long-run average based on the RTP you enter—not a prediction for one session. Volatility can produce a very different result. Operators can add max-bet rules, excluded games, expiry dates and maximum cashouts. Their live terms always override this estimate.
The formula behind the result
First calculate the bonus: deposit × match percentage, capped at the stated maximum. Then identify the wagering base. “35x bonus” uses the bonus alone; “35x deposit + bonus” uses both balances.
Multiply that base by the wagering number. Finally account for game weighting: slots may count 100%, while table or live games can contribute much less—or nothing. The theoretical expected-loss estimate applies the game's house edge (100% minus RTP) to that adjusted betting volume. Read the operator's live terms before claiming.
Put the number in context
Compare the result with the offer structure and how often you actually deposit. Large multi-deposit headlines only reach their maximum after every qualifying step.
Wagering calculator FAQ
- How do you calculate casino wagering requirements?
- Direct answer: multiply the amount covered by the requirement by the wagering multiplier. A €100 bonus at 35x bonus wagering means €3,500 of credited turnover. If the terms apply to deposit plus bonus, the base is larger.
- What does 35x wagering mean?
- Direct answer: 35x means the specified balance must be wagered 35 times. Check whether the operator means bonus only or deposit plus bonus — the difference can double the required turnover.
- How does game weighting change wagering?
- Direct answer: a game contributing 20% only credits €0.20 toward wagering for every €1 bet. You would need five times as much actual betting as a game weighted at 100%.
- Does the calculator predict how much I will lose?
- Direct answer: No. It estimates turnover, not losses, wins or cashout value. Casino games are random and operator rules such as max bets, exclusions, expiry and max cashout still apply.
