Use four calculations before you deposit: expected session cost, required wagering turnover, rakeback value, and a bonus's uncapped expected value. These are the same standard expected-value formulas used by casinos.
Expected cost is the long-run average: total wagered × house edge. Volatility means any single session lands far above or below it — find each slot's recorded RTP and source status in the database.
Select the exact base from the terms. A $100 bonus at 40× means $4,000 only when wagering applies to the bonus. If you actually deposited $250 and wagering applies to deposit + bonus, the base is $350 — even if the bonus was capped at $100.
This estimate applies the rakeback rate to theoretical loss: wager × house edge × rakeback rate. Programs can use different definitions, so check the casino's own rewards terms.
Enter the actual deposit whenever the terms include it; bonus percentage cannot recover that amount after caps or partial awards. The uncapped EV estimate is bonus − expected clearing cost. Weighting below 100% increases turnover; 0% means the game cannot clear it. A max-cashout clause can reduce value, but RTP alone cannot price that effect. Read the terms in our wagering guide.
All results are long-run expected values; short-term results vary wildly with volatility. 18+ · Play responsibly.
