Futures Position Size Calculator — How Many Contracts to Trade

Futures contracts have fixed multipliers that make position sizing different from stocks and forex. One ES contract moves $50 for every 1-point move in the S&P 500. One NQ contract moves $20 per Nasdaq point. You cannot buy fractional contracts, so the math must result in whole numbers. Here is how to size futures positions correctly.

Futures Contract Specifications

Contract	Symbol	$/Point	$/Tick	Tick Size	Typical Daily Range
E-mini S&P 500	ES	$50	$12.50	0.25	30-80 points
E-mini Nasdaq	NQ	$20	$5.00	0.25	100-300 points
Crude Oil	CL	$1,000	$10.00	0.01	$1-$4
Gold	GC	$100	$10.00	0.10	$10-$30
Micro E-mini S&P	MES	$5	$1.25	0.25	30-80 points
Micro E-mini Nasdaq	MNQ	$2	$0.50	0.25	100-300 points
Micro Gold	MGC	$10	$1.00	0.10	$10-$30
Micro Crude Oil	MCL	$100	$1.00	0.01	$1-$4

Position Sizing Examples

Account	Risk (1%)	Contract	Stop Loss	$/Point	Contracts	Actual Risk
$25,000	$250	ES	5 pts	$50	1	$250 (1%)
$25,000	$250	MES	5 pts	$5	10	$250 (1%)
$50,000	$500	NQ	25 pts	$20	1	$500 (1%)
$50,000	$500	MNQ	25 pts	$2	10	$500 (1%)
$10,000	$100	ES	5 pts	$50	0.4 (cannot trade!)	N/A
$10,000	$100	MES	5 pts	$5	4	$100 (1%)
$100,000	$1,000	CL	$1.00	$1,000	1	$1,000 (1%)

Notice: a $10,000 account cannot safely trade 1 ES contract at 1% risk with a 5-point stop (minimum risk = $250 = 2.5%). Micro futures solve this problem.

Why Small Accounts Need Micro Futures

The minimum position on ES is 1 contract. At $50/point:

Account	1 ES Contract, 5-pt Stop	Risk %	Verdict
$5,000	$250 loss	5.0%	Too much risk
$10,000	$250 loss	2.5%	Aggressive
$25,000	$250 loss	1.0%	Perfect
$50,000	$250 loss	0.5%	Conservative

With MES (1/10th size), a $5,000 account can trade 1 micro contract with a 5-point stop = $25 loss = 0.5% risk. Proper sizing becomes possible.

Futures Position Sizing Formula

Contracts = (Account x Risk%) / (Stop Loss in Points x Dollar Per Point)

Always round DOWN to the nearest whole contract. You cannot trade 1.7 contracts - trade 1. If the formula gives you less than 1, either use micro contracts or skip the trade.

Common Futures Sizing Mistakes

• Trading full-size with a small account: 1 ES contract on a $5,000 account means every 5-point stop is 5% of your account. Use micros instead
• Ignoring the multiplier: A "10-point stop" sounds small. On ES, 10 points = $500 per contract. On NQ, 10 points = $200. The multiplier is everything
• Using the same number of contracts for every trade: A 5-point stop and a 20-point stop require completely different contract counts to maintain the same dollar risk
• Forgetting commissions: Futures commissions ($2-$5 per contract round trip) matter more on micro contracts where each contract has a smaller P&L
