Win Rate &Expectancy

Home
Session tool · Not financial advice
Calculate your trading expectancy and projected monthly P&L. Most traders focus on win rate alone — but a 40% win rate with a 3:1 R:R is far more profitable than a 70% win rate with a 1:2 R:R. Expectancy tells you the real story.
Expectancy is the average amount you can expect to make per dollar risked over a large sample of trades. A positive expectancy means your strategy makes money over time. A negative expectancy means no amount of discipline or risk management will save you — the strategy itself is losing money. Most prop firm traders never calculate this number and wonder why they keep failing evaluations despite following their rules. This tool calculates your expectancy, your breakeven win rate, and projects your monthly P&L based on how many trades you take per day.

What is Expectancy?
Expectancy = (Win Rate × Avg Win)(Loss Rate × Avg Loss)

A positive expectancy means your strategy makes money over time regardless of any single trade result. A negative expectancy means you will lose money over time no matter how disciplined you are. Most prop firm traders with a 2:1 R:R only need to win 34% of their trades to be profitable.
Win rate alone means nothing. A 70% win rate with a 1:3 R:R (risking $300 to make $100) has negative expectancy — you lose money long term. A 40% win rate with a 3:1 R:R has strong positive expectancy. Focus on expectancy, not win rate. The 12-month projection assumes you reinvest profits — real results will vary.
