Futures Position Size Calculator Formula
How to Calculate Contracts
To calculate your futures position size manually, use this institutional formula:
For example, if you risk $500 on the E-mini Nasdaq 100 (NQ) with a 20-point stop loss:
$500 / (20 × $20) = 1.25 Contracts.
Since you cannot trade fractions, you round down to 1 Contract.
Forex Lot Size Logic
For Forex, risk is calculated based on Pips.
Switch the calculator to FOREX mode to instantly calculate Standard, Mini, or Micro lots for pairs like EURUSD and GBPUSD.
Why Risk Management Matters
The difference between a hobbyist and a professional trader is risk management. By using a Futures Position Size Calculator, you ensure that no single trade on ES, NQ, or Gold can damage your account significantly.
