i What this calculator does
This calculator works out your actual, realised win rate from your trade history, along with your average win and loss size, giving you a genuine snapshot of your strategy's real performance so far.
Enter your number of winning trades, losing trades, and average win/loss amounts, and the calculator returns your win rate and expectancy, learn more in our guide on why win rate alone means nothing without risk-reward context.
This calculator is for educational purposes only. Enter average loss as a positive number.
How to use the Win Rate Calculator
It works immediately. Change one value, leave the others, and the difference belongs to that change.
- 1. Winning Trades
- 2. Losing Trades
- 3. Average Win (R)
- 4. Average Loss (R)
The result panel reports:
- Total P/L Across all
Alongside the headline figures, the calculator reports win rate, expectancy per trade, total p/l, loss rate. Those are the numbers that usually explain why the headline result came out where it did.
The working appears below the result, step by step, so the figure can be checked rather than trusted.
Keep a record of the inputs you used alongside the result. Six months later the figure on its own tells you nothing about what you assumed to reach it.
Save the inputs with the output. When circumstances change, knowing which assumption moved is faster than running the whole thing again from memory.
Frequently asked questions
How is this different from the Break-Even Win Rate Calculator?
The Break-Even Win Rate Calculator tells you the win rate your strategy needs to reach, based on your risk-reward ratio, before you've traded it. This calculator tracks your actual, realised win rate from trades you've already taken, a genuinely different, after-the-fact measurement.
What's considered a good win rate for a trading strategy?
There's no universal answer, win rate alone doesn't determine profitability, a strategy with a 40% win rate and strong risk-reward can be more profitable than one with a 65% win rate and poor risk-reward, always consider win rate alongside your average win/loss size.
How many trades should I include before trusting my win rate figure?
More trades generally produce a more statistically reliable win rate, many traders look for at least 30-50 trades as a starting reference, with 100+ considered more robust for drawing firm conclusions about a strategy's true performance.
Should I include break-even trades in my win count?
This is a personal tracking choice, some traders count trades closed at exactly break-even as neither wins nor losses (excluded from the calculation), others count them as losses, be consistent with whichever convention you choose across your journal.
Does a declining win rate over time necessarily mean my strategy stopped working?
Not automatically, normal variance means win rate will fluctuate over any given stretch of trades, a genuinely meaningful decline is easier to identify by comparing win rate across larger, non-overlapping sample periods rather than reacting to short-term dips.
