How the Futures Lot Size Calculator Works
Futures trading requires precise calculation of position size based on:
- Account Balance: Total capital available for trading
- Risk Per Trade: The percentage of account balance you’re willing to risk on a single trade
- Stop-Loss Distance: The number of points you are willing to tolerate before exiting a trade
Step 1: Risk Calculation
Determine the dollar amount you are willing to risk per trade:
Risk Amount ($) = Account Balance × Risk Percentage Step 2: Determine Contract Risk
Calculate the dollar risk per contract based on stop-loss points and tick value:
Contract Risk ($) = Stop-Loss (points) × Tick Value ($ per point) Step 3: Calculate Lot Size
Divide the risk amount by the contract risk to determine the number of contracts to trade:
Lot Size = Risk Amount ÷ Contract Risk Plain Text Formulas
- Risk Amount:
Risk Amount = Account Balance × Risk Percentage - Contract Risk:
Contract Risk = Stop-Loss Points × Tick Value - Lot Size Calculation:
Lot Size = Risk Amount ÷ Contract Risk How to Use the Futures Lot Size Calculator

Example Calculations
Example 1: Single Contract Risk
- Account Balance: $50,000
- Risk per Trade: 2%
- Stop-Loss: 10 points
- Tick Value: $50
Step 1: Risk Amount
Risk Amount = 50,000 × 0.02 = $1,000 Step 2: Contract Risk
Contract Risk = 10 × 50 = $500 Step 3: Lot Size
Lot Size = 1,000 ÷ 500 = 2 contracts Result:
Trade 2 contracts to maintain 2% risk per trade.
Example 2: Adjusting Risk Percentage
- Account Balance: $100,000
- Risk per Trade: 1%
- Stop-Loss: 20 points
- Tick Value: $25
Step 1: Risk Amount
Risk Amount = 100,000 × 0.01 = $1,000 Step 2: Contract Risk
Contract Risk = 20 × 25 = $500 Step 3: Lot Size
Lot Size = 1,000 ÷ 500 = 2 contracts Result:
Trade 2 contracts to risk only 1% of your account.
