Profit Factor
Gross profit divided by gross loss — how many dollars you make for every dollar you lose.
Profit Factor, explained
Profit factor is total gross profit divided by total gross loss over a period. A profit factor of 1.0 is break-even; above 1.0 is profitable, and most robust, tradeable strategies sit somewhere around 1.3 to 2.0.
Unlike win rate, profit factor captures the size of wins and losses, not just how many there were. It is a quick health check on a track record: very high figures over small samples are often luck, while a steady factor above 1.2 over many trades suggests a real edge.
It is worth knowing what the number literally means. A profit factor of 1.5 says that for every $1 lost, $1.50 was won — so the gross winnings outweigh the gross losses by half again. That framing makes it easy to sanity-check: a claimed profit factor of 5 over thirty trades is almost certainly small-sample luck, not a durable edge.
Read it alongside maximum drawdown. A strong profit factor with a shallow drawdown is far more tradeable than the same profit factor earned through stomach-churning equity swings. The same 1.6 can come from a smooth grind or from a few enormous wins masking a violent equity curve.
On the desk we treat profit factor as one lens among several. We look at it together with expectancy, win rate and drawdown over a meaningful sample, because any single statistic can be flattered by a short run or an unusual market regime.
Frequently asked questions
- What is a good profit factor?
- Most robust, tradeable strategies sit around 1.3 to 2.0. Below 1.0 loses money; right at 1.0 is break-even. Very high figures (3+) over small samples are usually luck rather than a durable edge.
- What does a profit factor of 1.5 mean?
- For every $1 of gross loss, the strategy made $1.50 of gross profit — winnings outweigh losses by half again. It accounts for the size of wins and losses, not just how many there were.
