What Is Profit Factor in Trading?
Profit factor measures how many rupees a trading system earns for every rupee it loses, calculated by dividing total gross profit by total gross loss across all closed trades. A profit factor above 1 means the strategy is net profitable over the sample measured.
Formula
Profit Factor = Gross Profit ÷ Gross LossWorked example
Over a quarter, a trader’s winning trades add up to ₹1,80,000 in gross profit, and their losing trades add up to ₹90,000 in gross loss. Profit factor = 1,80,000 ÷ 90,000 = 2.0.
That means for every ₹1 this strategy loses, it earns ₹2 — a healthy, clearly profitable relationship between wins and losses, independent of how many trades were winners versus losers.
What's a good number?
A profit factor above 1 is technically profitable, but fragile — a small increase in costs or a short losing streak can flip it negative. 1.5 is generally considered a solid baseline, 2.0 is strong, and above 3.0 is excellent, though very high profit factors over small samples are often an outlier win skewing the number rather than a durable edge.
Below 1.2, treat the strategy as unproven — it is one bad month away from being unprofitable after real-world costs.
Common mistakes traders make with profit factor
- Calculating profit factor before subtracting brokerage, STT, and other transaction costs, which flatters the number versus what you actually keep.
- Using too small a sample size, so a single outsized winning trade dominates the ratio and misrepresents the system’s true edge.
- Looking at one blended profit factor across all strategies instead of calculating it per playbook, hiding which specific setups are actually working.
- Treating a high profit factor as the whole story while ignoring drawdown — a system can have an excellent profit factor and still be nearly unbearable to trade through its worst stretch.
TradeMind surfaces profit factor automatically for every playbook and strategy you log, alongside drawdown and expectancy, so you see the full risk picture, not just the ratio in your analytics dashboard.
