Ask a profitable trader for a single number to judge a strategy and many will say the same thing: profit factor. It's the closest thing trading has to a one-number health check — and most retail traders have never calculated their own.
What profit factor actually is
Profit factor is your gross profit divided by your gross loss over a set of trades. Add up every rupee your winners made, add up every rupee your losers cost, and divide the first by the second.
- Below 1.0 — you're losing money; your losses outweigh your wins.
- Exactly 1.0 — break-even before costs (and a net loss after brokerage and taxes).
- 1.25–1.5 — a real, tradeable edge.
- 1.5–2.0 — a strong system.
- Above 2.0 — excellent, and worth checking it isn't just a small, lucky sample.
Because it combines how often you win with how big those wins are, profit factor exposes broken systems that a flattering win rate hides. A trader winning 65% of the time can still have a profit factor below 1.0 if the occasional loss wipes out many small wins.
Why it beats raw P&L
Your total P&L can look fine because of one lucky trade, or look terrible during a normal drawdown in a healthy system. Profit factor normalises for that — it tells you about the process, not the mood of the last week. A consistent 1.6 profit factor across 200 trades is far more reassuring than a big green number built on two outliers.
The trap: profit factor on too few trades
Profit factor on 15 trades is noise. One big winner can push it to 3.0; one big loser can crush it to 0.6. It becomes meaningful somewhere around 50–100 trades, and trustworthy beyond that. Judge your system on a real sample, not last week.
How to calculate yours automatically
You could tally your winners and losers by hand in a spreadsheet — or log your trades once and have profit factor (plus win rate, expectancy, R-multiples and drawdown) computed instantly, updating with every trade. It also shows which setups and symbols carry your profit factor and which quietly drag it down.

- What is a good profit factor in trading?
- A profit factor above 1.0 means you're net profitable. 1.25–1.5 is a genuine edge, 1.5–2.0 is strong, and above 2.0 is excellent (verify it isn't from too small a sample). Below 1.0 means your losses outweigh your wins.
- How do you calculate profit factor?
- Divide your gross profit (the sum of all winning trades) by your gross loss (the sum of all losing trades, as a positive number). For example, ₹80,000 in wins and ₹50,000 in losses gives a profit factor of 1.6.
- Is profit factor better than win rate?
- Yes, as a single measure. Profit factor accounts for the size of your wins and losses, not just how often you win, so it reveals losing systems that a high win rate can disguise.
