Prop firm risk calculator
Your position size in a prop firm account should come from the maximum loss, not the profit target: divide the max loss by the losing streak you want to survive, then by your stop's dollar value per contract or lot. Enter your numbers below; the result is rounded down and also shows how many losses at that size reach the daily limit.

How it works
- Risk per trade = max loss ÷ losing trades to survive.
- Risk per contract/lot = stop distance × value per tick or pip.
- Size = risk per trade ÷ risk per contract, rounded down.
- With an intraday trailing drawdown, open profit raises the floor — use a larger losing-streak number.
FAQ
- How do I calculate position size for a prop firm account?
- Divide the max loss by the number of consecutive losses you want to survive to get your dollar risk per trade, then divide that by stop distance × value per tick (or pip) to get contracts or lots, rounded down.
- What tick value should I use?
- Use your instrument's contract specification: for example $12.50 per tick on E-mini S&P 500 (ES), $1.25 on Micro E-mini (MES), $5 on E-mini Nasdaq (NQ) and $0.50 on Micro Nasdaq (MNQ). For forex, a standard lot is about $10 per pip on USD-quoted pairs.
