Formula and calculation

Run repeated browser-based bet sequences from fixed odds, win probability, stake, and bankroll assumptions to explore possible bankroll paths.

Each simulated win adds stake × (odds − 1); each loss subtracts stake. A trial is marked ruined when the bankroll cannot fund the next fixed stake.

Calculations run locally in your browser. No betting data is transmitted.

Worked example

With a $1,000 bankroll, $25 fixed stake, 2.00 odds, and 50% win probability, the mathematical expected bankroll after 100 bets remains $1,000, while simulated paths vary.

Assumptions and limits

Fixed probability and odds ignore changing markets, limits, correlation, and estimation error. More trials reduce simulation noise but do not repair unrealistic assumptions.

This informational tool does not recommend a wager or guarantee a result. Confirm operator terms and local rules.

When are displayed figures rounded?

Calculations use JavaScript numeric precision and values are rounded only for display, normally to two decimal places.

Does a positive result mean the bet will win?

No. The output describes the entered numbers and assumptions; it does not predict an event or guarantee a return.
