Trade Analysis
Win Rate & Expectancy Calculator
A win rate and expectancy calculator turns your trade wins, losses, and average win/loss into win rate, expectancy per trade, and profit factor. Traders use it to judge whether a system is profitable over many trades, not from a single lucky streak.
Calculate win rate, expectancy, and profit factor from your trade results.
Frequently asked questions
What is trading expectancy?
Expectancy is the average amount you expect to win or lose per trade over many repetitions. Positive expectancy means the strategy is profitable before costs; negative expectancy means it loses over time.
How do I calculate win rate from trading results?
Win rate = winning trades ÷ total trades × 100. Use closed trades only and the same date range you use for average win and average loss.
