Position size calculator
Decide how much you are prepared to lose first, then let the calculator size the position to match your stop-loss distance.
Position size
- Lots (rounded down)
- 0.40
- Units
- 40,000
- Amount at risk
- 100.00 USD
- Risk at the rounded size
- 100.00 USD
- Value per pip per lot
- 10.00 USD
Lots = (balance × risk %) ÷ (stop distance × value per pip per lot). Spreads, commission and slippage can make the real loss larger than planned.
