Drawdown Survival + Risk of Ruin Calculator
Built for serious traders. Estimate account survival, risk of ruin, and prop firm rule violations. Supports daily loss resets and trailing drawdown rules.
Inputs
Display only (no FX conversion).
Used to show money amounts.
Measured from each day start equity.
Trailing from peak equity (high-water mark).
ON = harder after profits (peak moves up). OFF = fixed overall limit from the start.
What this means
This tool is designed for traders who want to survive long enough to let their edge work. Most accounts fail from poor position sizing and drawdown rule violations — not from lack of indicators.
Prop Firm Mode simulates a daily loss rule that resets each day plus an overall max loss rule. If trailing drawdown is ON, the overall limit follows your peak equity (high-water mark).
FAQ
What is trailing drawdown?
Trailing drawdown means your overall max loss is calculated from your peak balance (high-water mark). After you make profits, the allowed drawdown level can move up, making the rule tighter.
How does daily reset work?
Each simulated day starts with that day’s equity. If you breach the daily loss limit within the day, you fail the rules — then the daily limit would reset next day (but the failure already happened).
