Why Use the Futures Position Size Calculator?
One ES contract controls $250,000+ of S&P 500 exposure. Trading even one contract more than your risk allows can turn a manageable stop-loss into an account-threatening event. This calculator gives you the exact number of contracts so your risk stays precisely within your 1–2% rule regardless of stop loss size.
Formula Used
Contracts = (Account Balance × Risk %) ÷ (Stop Loss Ticks × Tick Value)Worked Example
$75,000 account, 1% risk ($750), trading ES with a 12-tick stop (3 points). Tick value = $12.50. Stop loss cost per contract = 12 × $12.50 = $150. Contracts = $750 ÷ $150 = 5 contracts. Total dollar risk = 5 × $150 = $750 (exactly 1% of account). At 2:1 R:R target (24 ticks), potential profit = 5 × 24 × $12.50 = $1,500.
How to Use the Futures Position Size Calculator — Step by Step
- 1
Select your futures contract
Choose your contract from the dropdown: ES, NQ, MES, MNQ, YM, CL, or GC. Each contract has a different tick size and tick value that the calculator uses automatically.
- 2
Enter your account balance
Input your total trading account balance in USD. The calculator uses this with your risk percentage to determine the maximum dollar risk per trade.
- 3
Set your risk percentage
Enter the percentage of your account you are willing to risk. Professional futures traders typically risk 1–2% per trade. For a $25,000 account at 1% risk, maximum loss = $250.
- 4
Enter stop loss in ticks
Enter your stop loss distance from entry in ticks. For example, if you are trading ES and your stop is 8 ticks (2 points) away from entry, enter 8.
- 5
Read your contract count
The calculator shows how many contracts to trade, your total dollar risk, and risk per contract. Always round down to the nearest whole number — you cannot trade fractional futures contracts.
What Your Futures Position Size Calculator Results Mean
Number of Contracts
The maximum number of contracts you should trade to keep risk within your defined percentage. Always round down — you cannot trade fractional futures contracts.
Dollar Risk
The total dollar amount at stake if your stop loss is hit. This should equal your account balance × risk percentage. Verify this matches your intended risk before placing the trade.
Risk as % of Account
Confirms that the calculated contract count produces the correct percentage risk. Should match your intended risk percentage (e.g. 1.0%). Small rounding differences are normal due to integer contract counts.
Futures Position Size Calculator — Frequently Asked Questions
Q.How do I calculate futures position size?
Futures position size = (Account Balance × Risk %) ÷ (Stop Loss in Ticks × Tick Value per Contract). Example: $50,000 account, 1% risk = $500 max loss. ES stop = 10 ticks × $12.50 = $125 risk per contract. Contracts = $500 ÷ $125 = 4 contracts.
Q.What is the tick value of ES, NQ, MES, and MNQ?
ES: 1 tick = $12.50 (0.25 points). NQ: 1 tick = $5.00 (0.25 points). MES: 1 tick = $1.25 (0.25 points). MNQ: 1 tick = $0.50 (0.25 points). YM: 1 tick = $5.00 (1 point). CL: 1 tick = $10.00 ($0.01/barrel). GC: 1 tick = $10.00 ($0.10/oz).
Q.How many ES contracts should a $25,000 account trade?
At 1% risk ($250) with a 10-tick stop loss: $250 ÷ (10 × $12.50) = $250 ÷ $125 = 2 contracts. At a 20-tick stop: $250 ÷ $250 = 1 contract. Tighter stops allow more contracts; wider stops require fewer. Never exceed your calculated number.
Q.Should I trade ES or MES as a beginner?
Start with MES (Micro E-mini S&P 500). The MES is 1/10th the size of ES with a tick value of $1.25 vs $12.50. A $5,000 account can trade MES with proper position sizing whereas the same account would be over-leveraged trading full ES contracts. Master position sizing on MES before scaling to ES.
Q.What percentage of account should I risk per futures trade?
Most professional futures traders risk 1–2% per trade. Prop firm traders often target 0.5–1% per trade to protect their funded accounts. At 1% risk on a $50,000 account, your max loss per trade is $500. This ensures even 10 consecutive losses only cost 10% of your account, giving you room to recover.
