Quick answer

This calculator makes promotion assumptions visible. It does not promise profit and it cannot model every term, variance or bankroll-ruin scenario.

Estimate bonus turnover and theoretical game cost

Enter the promotion assumptions.

Formula

Credited requirement = requirement base × multiplier. Actual action = credited requirement ÷ contribution rate. Theoretical game cost = actual action × house edge.

Interpretation

Bonus amount minus theoretical game cost is only a first-pass benchmark. Restrictions and variance can make practical value materially lower.

Use current terms

Enter the exact requirement base, contribution and game assumptions from the promotion you are evaluating.
