Profit Factor Calculator
Divide gross positive realized outcomes by the magnitude of gross realized losses from one entered sample. The result describes the supplied records; it does not rate a strategy or predict future performance.
Enter one realized sample
Use one signed, same-unit outcome per line after the costs you intend to include.
Positive is profitable, negative is losing and zero is flat. Do not mix currencies, percentages, pips and R-multiples.

How observed profit factor is calculated
Zero outcomes remain in the sample count but add nothing to either gross total. Full precision is retained until display.
Worked example from the audited fixture
For realized outcomes of $400, −$200, $150, −$100 and $50, gross profit is $600 and the magnitude of gross loss is $300. Profit factor is therefore 600 ÷ 300 = 2.00. The same five-record sample has a net outcome of $300 and an average outcome of $60.
How to interpret the result
A 2.00 profit factor means gross positive outcomes in this entered sample were twice its gross losses. It does not show when the losses occurred, the drawdown path, whether records or costs are missing, or whether the ratio will persist. If there are no losing outcomes, the denominator is zero and this page reports profit factor as unavailable rather than infinity.
Assumptions and limits
- All rows must use one consistent unit and realization basis.
- Open positions, omitted costs and incomplete records can materially change the result.
- Order, path, drawdown, sample uncertainty and changing market conditions are not modeled.
- A larger ratio is not automatically safer, more robust or suitable.
- No result is a forecast, verified edge, grade or recommendation.
Frequently asked questions
- It compares gross positive realized outcomes with the magnitude of gross realized losses in the entered sample.
- Enter losses as negative numbers. The model converts their aggregate to a positive denominator magnitude.
- The numeric ratio is shown as undefined because gross loss is zero. Other descriptive totals remain available.
- Yes. They remain in the sample and average-outcome denominator but add nothing to gross profit or gross loss.
- Use one consistent record basis. If you intend to assess results after costs, enter outcomes after those verified costs.
- The arithmetic works with any one consistent signed unit, but the display currency selector is only a label. Do not mix units.
- No. Profit factor is a gross-profit-to-gross-loss ratio. Expectancy is the average outcome per trade.
- No. It describes only the entered realized sample and contains no future-performance model.
Sources and methodology
- Fidelity — Strategy-testing glossary — defines profit factor as gross profit divided by gross loss and distinguishes realized test records.
- CFTC — Trading system claims advisory — limitations of hypothetical and past-performance claims.
