Risk of Ruin Calculator
Simulate the risk of reaching a loss threshold using win rate, payoff and risk per trade. Review model assumptions before interpreting the estimate.
How to use this calculator
Use consistent currency units and net trading results where fees apply. Check the model assumptions shown with the result. Historical win rates and average payoffs do not guarantee future performance.
Limits and validation
Broker contract specifications, rounding rules, funding, gaps and execution costs can change the actual outcome. Liquidation estimates apply only to the stated isolated linear model. Risk of ruin uses independent fixed-payoff simulated trades and a fixed fractional risk model.
