What is my trade expectancy per trade if I know my win rate, average winner, and average loser?

How this is calculated

• Expectancy per trade equals (win rate × average winner) minus (loss rate × average loser). Loss rate is assumed to be 100% minus your win rate.
• This is the average dollar result you'd expect on a single trade, over a large enough sample, if your actual future win rate and average win/loss sizes end up matching the ones you entered.
• Profit factor is the ratio of total expected winning dollars to total expected losing dollars implied by these stats. A profit factor above 1 means the numbers you entered describe a strategy that makes money over time. Below 1 means it loses money over time.
• Break-even win rate needed is the minimum win rate that would make expectancy exactly zero, given your entered average winner and average loser. It equals average loser divided by the sum of average winner and average loser.
• If you enter a number of trades, the projected total simply multiplies expectancy per trade by that count. It assumes your win rate and average win/loss sizes stay constant, which rarely holds true over an actual trading history.
• This does not include commissions, fees, taxes, or slippage, all of which lower your actual expectancy below this estimate.
• This calculator uses the numbers you enter. It does not pull your actual trade history and does not verify that your past win rate or average win/loss sizes will continue into the future.
