    Win Rate & Expectancy Calculator for Your Strategy

    A high win rate means nothing if your losses are bigger than your wins. Plug in your results and see the numbers that actually decide profitability.

    Win rate is only half the story

    A 40% win rate with 3:1 winners beats a 70% win rate with tiny gains and huge losses. Expectancy — average profit per trade — is the metric professionals track.

    How It Works

    1

    Enter wins and losses

    From your last 20–100 trades or a backtest.

    2

    Add average win size

    The average dollar profit on your winning trades.

    3

    Add average loss size

    The average dollar loss on your losing trades.

    4

    Read your expectancy

    Positive means an edge; negative means stop trading it.
