Profit factor is one of the most useful trading metrics because it compares how much money your winning trades generated with how much your losing trades gave back.
If your winning trades generated $15,000 and your losing trades totaled $10,000, your profit factor would be 1.50. That means your strategy generated $1.50 in gross profits for every $1.00 lost.
So what is a good profit factor?
There is no universal cutoff, but a simple framework is:
- Below 1.00: Historically unprofitable over the measured sample
- Around 1.00: Roughly breakeven before costs
- 1.10 to 1.25: Positive, but relatively thin margin
- 1.25 to 1.75: Potentially solid historical performance
- 1.75 to 2.00 and above: Strong historical results, assuming the sample is meaningful
A higher number is not automatically better. A profit factor of 3.0 based on 12 trades may be much less meaningful than a profit factor of 1.55 across 500 trades.
Sample size matters
Imagine a trader with five trades: +$100, +$150, +$125, -$100, +$2,500. The profit factor looks extremely strong because one large winner dominates. Now imagine another trader producing a 1.50 profit factor over 600 trades with relatively consistent outcomes. The second dataset provides much more useful information about actual performance.
Profit factor should be stable
A useful question is not simply what your profit factor is. Instead ask how stable it is. Compare your last 25, 50, 100, 250, and all trades. If your lifetime profit factor is 1.60 but your last 100 trades are at 0.92, something may have changed worth investigating.
Analyze profit factor by strategy
Overall profit factor can hide major differences. For example: breakouts 1.82, reversals 0.74, trend continuation 1.47. Your total account might still be profitable but one setup could be dragging down your results. You can also calculate profit factor by instrument, time of day, day of week, long vs short trades, and market condition.
Profit factor is not enough by itself
Use it alongside win rate, average winner, average loser, expectancy, maximum drawdown, and total number of trades. A strategy can have an attractive profit factor while still experiencing drawdowns that are difficult to tolerate.
Track your own profit factor
MyTraderScore can calculate profit factor from your trading history and help you compare it with other metrics that give the number context. The goal is not to reach someone else's idea of a perfect profit factor. The goal is to understand whether your own trading process has historically produced more gross profits than gross losses and how consistently it has done so.
