What Is a Good Profit Factor in Trading?

Profit factor is gross profit divided by gross loss. If your winning trades add up to 4,200 and your losing trades add up to 3,100, your profit factor is about 1.35. It condenses a record into one comparison: how much you made for every unit you lost.

Reading it is straightforward at the extremes. Above 1, your winners outweighed your losers, so you were profitable before costs you left out. Below 1, you lost money. At exactly 1 you broke even. But there is no profit factor that is good in itself, because the question is always good compared to what, and over how many trades.

It links directly to win rate and payoff. If you win 40% of trades and your average win is 1.5 times your average loss, your profit factor is exactly 1: you break even. At a 50% win rate with the same payoff, it is 1.5. This is why the figure can be raised in two ways, by winning more often or by making wins larger compared with losses, and why two very different traders can share the same value.

Its weaknesses are worth knowing. It ignores the order of results, so it does not show how deep the losing periods were, and a high profit factor can come with a painful drawdown. It is sensitive to a single large win, which can lift the number on its own. And it takes no account of how many trades are behind it, so a high figure from a small sample is weak evidence.

Used with those cautions, it is a good first check. Read it alongside expectancy, maximum drawdown and the number of trades, and judge it after fees. The analyzer reports all of those from your own history.
