How profit factor is calculated
Profit factor = gross profit ÷ gross loss. Add up every winning trade to get gross profit, add up every losing trade (as a positive number) to get gross loss, then divide.
For example, if your winners add up to $4,500 and your losers add up to $3,000, your profit factor is 4,500 ÷ 3,000 = 1.5.
| Profit factor | What it usually means |
|---|---|
| Below 1.0 | Losing. Total losses exceed total profits. |
| 1.0 to 1.3 | Thin edge. Trading costs can erase it. |
| 1.3 to 2.0 | Solid, if it holds over many trades. |
| Above 2.0 | Strong, but check the sample size before trusting it. |
These bands are common rules of thumb, not guarantees. Past results don’t predict future performance.
Other numbers worth tracking
- Payoff ratio: your average win divided by your average loss.
- Break-even win rate: the win rate you need, at your payoff ratio, to make nothing and lose nothing.
- Expectancy: the average amount you make or lose per trade, including the wins and the losses.

Profit factor questions
What is profit factor?
Profit factor is your gross profit divided by your gross loss. A value of 1.5 means you made $1.50 on winning trades for every $1.00 you lost on losing trades. Above 1 is profitable, below 1 loses money.
What is a good profit factor?
As a rule of thumb, 1.3 to 2 is solid and above 2 is strong, but only across a large sample. A profit factor of 3 from 12 trades says very little. Costs such as spread and commission also reduce your real result, so a figure under about 1.2 can disappear after fees.
Is profit factor the same as win rate?
No. Win rate is the percentage of trades that win. Profit factor compares the size of your total profits to your total losses. A trader who wins only 35% of trades can have a profit factor above 1.5 if the winners are much bigger than the losers.
How many trades do I need for profit factor to mean anything?
There is no exact number, but many traders look for at least 30 trades, and more is better. With few trades, one large win or loss can swing the result.
What does an infinite profit factor mean?
It means you entered profits but no losses, so the formula divides by zero. Check that you included every losing trade.
