What is Profit Factor — And Why It's the One Metric to Watch
May 29, 2026
Profit factor is the single most useful trading-performance metric most traders ignore in favour of win rate. Here's what it is, why it matters, and how to use it.
The formula
Profit Factor = Gross Profit ÷ Gross Loss. If your winning trades total $10,000 and your losing trades total $5,000, your profit factor is 2.0.
Above 1.0 means you're net-positive. Below 1.0 means you're net-negative. The further from 1.0, the more skewed your distribution is.
Why it beats win rate
Win rate tells you how often you're right. Profit factor tells you whether being right has paid you. A 70%-win-rate trader who lets losses run twice as far as winners has a profit factor of 0.86 — losing money — while a 35%-win-rate trader who cuts losses tight and lets winners breathe can sit at 1.8.
Profit factor captures both expectancy and discipline in a single number, which makes it more useful for review than either piece in isolation.
What's a good profit factor?
For futures day traders, profit factor above 1.5 over a 90-day window is solid. Above 2.0 is strong. Below 1.2 is unstable — small changes in execution can flip you net-negative.
Single-day or single-week profit factors are noisy and not useful for evaluation. Look at rolling 60-day or 90-day windows.
How to use it in review
Track profit factor week-over-week and look for trends, not absolute values. Falling profit factor with stable win rate means losers are growing — usually a discipline issue. Falling win rate with stable profit factor means setups are working less often but you're still cutting losses well.
TradeRR computes profit factor on a rolling basis and surfaces it in the dashboard alongside win rate and expectancy so you can read the three together.
Frequently asked questions
What is a good profit factor for day trading?
Above 1.5 over a 60-90 day window is solid; above 2.0 is strong; below 1.2 is unstable. Single-week values are too noisy to evaluate.
Is profit factor better than win rate?
Profit factor captures both expectancy and discipline in one number, which makes it more useful in isolation. But the two read best together — both moving in the right direction is the signal you want.
How do I calculate profit factor?
Gross profit (sum of all winning trades) divided by gross loss (absolute sum of all losing trades). Above 1.0 means net-positive.
