This calculator shows what a given win rate, payout and stake would produce on average over a series of trades. It is a way to test your own assumptions, not a forecast. If the average result comes out negative, the win rate you entered is below break-even at that payout.
Profit and Expectancy Calculator
This is arithmetic on the numbers you enter, not a forecast. Real results vary around the average, and a negative figure means the win rate you entered is below break-even at that payout.
How to Use This Calculator
- Enter the stake per trade and the payout your platform quotes.
- Enter the number of trades and the win rate you want to test.
- Compare the average result with zero, and the win rate with the break-even rate shown.
The Maths Behind It
The average result per trade is the win rate times the profit on a win, minus the loss rate times the stake. Multiplying by the number of trades gives the average total. Real results scatter around that average, and a short series can differ widely from it; see the guide on sample size linked below.
Limits
This tool uses only the figures you enter. It does not know your broker, your fees or your market, and its output is not advice or a prediction. Test any strategy on a demo account first, and read your platform's own terms.
Frequently Asked Questions
Can this tell me what I will earn?
No. It shows the average implied by the numbers you enter. Actual results vary, and the win rate you will achieve is unknown.
What win rate should I enter?
Use a rate measured from a large, honest record such as a journal or demo log, rather than a hoped-for figure.
Why does a 55% win rate lose at some payouts?
If the payout is low, the break-even win rate rises above 55%, so the average result turns negative.
