Trade Expectancy Calculator
A system only makes money if the math is positive. Enter your win rate and average win and loss (in dollars or R) to get expectancy per trade, your profit factor, and the projected result over 100 trades.
FAQ
What is trade expectancy?
Expectancy is the average amount you can expect to win or lose per trade: (win rate × average win) − (loss rate × average loss). A positive number means a profitable edge over many trades.
What is profit factor?
Profit factor = gross profit ÷ gross loss. Above 1.0 is profitable; many traders look for 1.5 or higher. It tells you how many dollars you make for every dollar you lose.
Should I use dollars or R?
Either — just keep average win and average loss in the same unit. Entering them in R (multiples of your risk) makes the result comparable across account sizes.
