What is a Trade Expectancy Calculator?

Trade expectancy combines win rate, average winner and average loser into one estimate of the average result per trade. Positive historical expectancy does not guarantee that future trades will remain profitable.

Formula

Expectancy = (Win rate × Average win) − (Loss rate × Average loss)

Example calculation

A 50% win rate, $200 average win and $100 average loss produces $50 estimated expectancy per trade before costs.

How to use this tool responsibly

  • Use net results after costs.
  • Update with new trades.
  • Review drawdown alongside expectancy.
