Betting Bankroll Ruin
A precise tool.
What is the Betting Bankroll Ruin & How does it work?
The Kelly criterion determines the optimal fraction of your bankroll to wager on each bet when you have a positive edge, maximizing long‑term growth while controlling risk.
Risk of ruin quantifies the probability that a series of bets will deplete your bankroll to zero, even when you follow the Kelly fraction. It is crucial for bankroll management and psychological comfort.
Using the Kelly fraction f and current bankroll B, the probability of eventual ruin can be expressed analytically, allowing you to see how changes in bankroll size or edge affect safety.
R = left( frac{1 – f}{1 + f} right)^{frac{B}{2f}}
R = probability of ruin
