Why Position Sizing Matters in Futures Trading
Position sizing determines how many contracts you can safely trade without exposing your account to excessive risk. Many traders focus too much on entry and exit strategies but forget that risk control is what keeps them in the game.
Proper position sizing helps you:
- Avoid over-leveraging your trades
- Maintain consistent risk per position
- Protect your trading capital
- Improve emotional discipline
- Ensure sustainable account growth
The Futures Position Size Calculator is built to make this process fast, simple, and accurate.
How the Futures Position Size Calculator Works
The calculator uses a simple but effective formula based on your trading parameters. Here’s how it calculates your position size and risk amount:
Formula Explanation
- Risk Amount = Account Balance × (Risk % ÷ 100)
- Position Size (contracts) = Risk Amount ÷ (Stop Loss × Contract Value per Point)
This ensures your total loss on a trade does not exceed your chosen risk percentage, no matter what your stop loss level is.
How to Use the Futures Position Size Calculator
Follow these easy steps to get accurate position sizing for your trades:
- Enter Your Account Balance
Input your total trading capital (for example, $10,000). - Enter Risk per Trade (%)
Specify what percentage of your account you’re willing to risk per trade (e.g., 1% or 2%). - Enter Stop Loss (Points)
This is the number of points you are willing to lose if the trade goes against you. - Enter Contract Value per Point ($)
Define how much one point is worth per contract. For example, if one point equals $5, enter “5.” - Click on “Calculate”
Instantly see your position size (number of contracts) and the risk amount in dollars. - Click “Reset” to start over with new inputs.
The results will appear below the form, showing exactly how many contracts to trade and how much you are risking.
Example of a Futures Position Size Calculation
Let’s go through a real-world example:
- Account Balance: $10,000
- Risk per Trade: 2%
- Stop Loss: 5 points
- Contract Value per Point: $20
Step 1: Calculate Risk Amount
Risk Amount = $10,000 × (2 ÷ 100) = $200
Step 2: Calculate Position Size
Position Size = $200 ÷ (5 × $20) = $200 ÷ $100 = 2 contracts
✅ Result: You should trade 2 contracts, risking $200 in total (2% of your account).
This simple calculation helps you stay disciplined and prevent oversized losses.
