How it works

Enter balance, risk %, entry, and stop. The calculator returns a size that keeps dollar risk within limits, which makes it easier to survive losing streaks and compare trades on the same risk basis instead of changing size impulsively.

Formula

Position Size = (Account Balance × Risk %) ÷ (Entry − Stop) for longs. The smaller your allowed risk or the wider your stop distance, the smaller the position needs to be. That tradeoff is what keeps risk controlled.

Example

Balance $10,000, risk 1%, entry $100, stop $95 → size ≈ $2,000. A $5 move equals $100 risk (1%). If the same trade required a much wider stop, the calculator would force a smaller position, which is exactly what protects the account from oversized losses.

Tips

Set risk first, then size—never the other way around.
Adjust size when volatility widens stops.
Align with risk/reward targets before placing orders.
