Prop-firm challenge calculator
How many trades a target takes at your win rate and reward-to-risk, and how many losses in a row your risk per trade survives before each loss line.
What that implies

- 1,000
- Expectancy per trade
- 0.35R
- Trades to the target at that expectancy
- 29

What this calculator assumes
- Expectancy is win rate times reward-to-risk, less the losses. It is an average; a real run is streakier than its average.
- The trades-to-target figure is the target divided by expectancy times risk per trade, rounded up. It is not a probability of passing.
- The losing-streak figures are consecutive losses that leave the line still open; the loss that reaches it ends the day or the account.
- The figures it opens with are an example. It runs in your browser and stores nothing.
- A prop firm measures its own rules on its own server, in its own time zone, with its own rounding. This shows where you stand by the arithmetic above; the firm’s measurement is the one that ends an evaluation.
