Expected Loss Calculator for Casino Sessions.
Estimate theoretical casino loss from wager size, house edge, rounds per hour, and playing time. Includes the formula, assumptions, and interpretation.
How this calculator works
Expected loss equals average wager × decisions per hour × hours played × house edge. For a $25 wager, 50 rounds per hour, two hours, and a 2.7% edge, total action is $2,500 and expected loss is $67.50.
Assumptions and limits
Use the edge for the exact wager and rule set. The result is a long-run average, not a prediction of what one session will lose.
Interpretation: Calculator results are long-run mathematical estimates under the entered assumptions. They are not session predictions, guarantees or recommended loss limits.
