Risk of Ruin Calculator

If these numbers were a coin, how often would the account hit the floor?

This worksheet computes a paper Risk of Ruin from a win rate you type, a reward-to-risk ratio, and a percent risked per trade. It does not estimate your win rate.

All you need is win rate %, R:R, risk per trade %, and a ruin floor. Optional: trade count for the seeded simulation.
