What is a good profit factor for a trading strategy?
Profit factor tells you how much you make for every dollar you lose. Enter your gross profit and gross loss (or your average win, average loss, and trade counts) and get the ratio, its interpretation, and where it sits against the standard bands.
How it works
Profit factor is gross profit divided by gross loss
Profit factor equals gross profit divided by the absolute value of gross loss. Gross profit is the sum of every winning trade's P&L; gross loss is the sum of every losing trade's P&L, taken as a positive number. A profit factor of 2 means you made two dollars for every dollar you lost across the trades in the sample.
- 01
Pull gross profit and gross loss from your trade history
Add up the P&L of every winning trade for gross profit, and every losing trade for gross loss. Most journal or broker exports can filter by result and sum a column directly.
- 02
Enter the totals, or the averages and counts
If you already have the two totals, use Totals mode. If you only know your average win, average loss, and how many of each you had, switch to Averages mode — it multiplies those out for you.
- 03
Read the number against the band
The calculator shows the ratio to two decimals and which of the five standard bands it falls in, from losing money to outstanding.
- 04
Weigh it against your sample size
A profit factor from 10 trades is close to noise. The same ratio from 200 trades is a real signal. Check the trade count behind the number before you act on it.

Two ways to calculate it
Totals mode divides gross profit by gross loss directly. Averages mode multiplies average win by win count and average loss by loss count first, then does the same division, and also shows your win rate since it already has the counts. Everything runs in your browser — nothing is saved or sent anywhere.
Enter totals if you already have them, or averages plus trade counts.

| Profit factor | Band | What it means |
|---|---|---|
| Below 1.0 | Losing | The system loses money overall — gross loss outweighs gross profit. |
| 1.0 – 1.5 | Marginal | Barely profitable. Costs, slippage, or one bad stretch can flip this negative. |
| 1.5 – 2.0 | Good | A solid, tradeable edge. |
| 2.0 – 3.0 | Excellent | A strong edge, worth protecting and repeating. |
| Above 3.0 | Outstanding | Very strong — but check the sample size before trusting it. |
Review
A single profit factor number can mislead you
Profit factor on 10 trades is close to meaningless — a couple of results either way can swing it dramatically. It also says nothing about drawdown: a strategy can have a high profit factor and still string together a losing streak that's hard to sit through. And a very high profit factor, especially on a small sample, usually means one outlier win or too few losing trades yet, not a discovered edge.

This calculator works off numbers you type in by hand. Traders Journal computes profit factor, win rate, drawdown, and the rest directly from your logged trades, and keeps it updated as you add more.

What is a good profit factor?
Above 1.5 is generally considered solid, 2.0 to 3.0 is strong, and above 3.0 is outstanding but worth double-checking against your sample size. Below 1.0 means the strategy is losing money overall; between 1.0 and 1.5 is marginal and can turn negative with costs, slippage, or a bad run.
What is the difference between profit factor and win rate?
Win rate is the percentage of trades that were profitable. Profit factor is the ratio of total money made to total money lost. A strategy can have a low win rate but a high profit factor if its winners are much bigger than its losers, and vice versa — the two numbers answer different questions and neither one alone tells the full story.
Can profit factor be negative?
No. Profit factor is a ratio of two amounts that are both treated as positive (gross profit and the absolute value of gross loss), so the result is never negative. A losing strategy shows a profit factor below 1.0, not a negative number.
How many trades do I need before profit factor is meaningful?
There's no strict cutoff, but treat anything under 30 to 50 trades as a rough early read rather than a settled result. The fewer trades in the sample, the more a single big win or loss can swing the ratio.
Does profit factor account for drawdown?
No. Profit factor only looks at the total gross profit and gross loss across a sample — it says nothing about the order the trades happened in, or how deep or long any losing streak got. Two strategies can have the same profit factor while one is far harder to trade because of its drawdown.
