Trading one futures contract costs far less than the value of the asset it controls, but “how much does a futures contract cost” has several answers stacked on top of each other. You post a margin deposit that typically runs 3% to 12% of the contract’s notional value — often a few thousand to tens of thousands of dollars for popular contracts. On top of that, each trade carries a few dollars per contract in commissions, exchange fees, and a small regulatory charge, plus the bid-ask spread, a monthly platform or data subscription, and, eventually, taxes on your gains.
The Margin Deposit
The biggest number you need to have ready isn’t a purchase price. It’s the initial margin, a performance bond that stays locked in your account as collateral against potential losses. Federal law requires futures commission merchants to hold these customer funds in accounts separate from the firm’s own money.1Office of the Law Revision Counsel. 7 U.S. Code 6d – Dealing by Unregistered Futures Commission Merchants or Introducing Brokers Prohibited
The deposit is a fraction of the contract’s full notional value, typically 3% to 12% depending on how volatile the underlying asset is. CME Group lists a maintenance performance bond of roughly $24,200 for one E-mini S&P 500 contract.2CME Group. E-mini S&P 500 Futures Margins With the index near 5,900 and a $50 multiplier, that contract controls about $295,000 in notional exposure, so the margin works out to roughly 8%.3CME Group. E-mini S&P 500 Futures and Options Less volatile products require less; commodities prone to sharp swings require more.
Smaller contracts bring the entry cost down. The Micro E-mini S&P 500 uses a $5 multiplier — one-tenth the standard size — with margin requirements and exchange fees scaled down proportionally.4CME Group. Micro E-mini S&P 500 Index Futures
Your broker can set its own margin requirement above the exchange minimum, and often does during volatile periods. These “house margins” give the brokerage an extra cushion. Check the number your broker actually charges, not just the exchange figure.
Day-Trading Margin Versus Overnight Margin
If you plan to open and close within the same session, the deposit can be dramatically smaller. One brokerage lists a day-trading margin of just $400 for the E-mini S&P 500, compared to an overnight maintenance margin above $26,000 at the same firm.5AMP Futures. Futures Margin Calculator The Micro E-mini S&P 500 may require as little as $40 intraday at some brokers versus roughly $2,600 overnight.
The catch: if you’re still holding when the overnight session begins, your broker applies the full exchange maintenance margin. If your account doesn’t have the funds to cover it, you’ll face an immediate margin call or forced liquidation.
Per-Trade Costs
Every trade carries direct, per-contract fees. Charges apply on each side (open and close) or as a single round-turn fee covering both. There are three main pieces:
- Broker commissions. What your brokerage collects for routing and execution. Depending on tier, commissions typically range from under $1 to several dollars per contract per side.
- Exchange and clearing fees. The exchange and its clearinghouse charge separately for matching orders and guaranteeing settlement. For the E-mini S&P 500, a non-member trading electronically pays roughly $1.38 per side in exchange fees; exchange members pay significantly less.6CME Group. Clearing and Trading Fees
- NFA assessment fee. The National Futures Association charges $0.02 per side on every futures contract traded in the United States, invoiced through your broker. The fee applies to all contract sizes and all domestic exchanges, with the only exception being traders who hold formal membership privileges on the exchange where the trade is executed.7National Futures Association. NFA Assessment Fees FAQs8National Futures Association. 9016 – NFA Bylaw 1301: NFA Assessment Fee Questions and Answers for FCMs
Added together, a round-turn trade on one E-mini S&P 500 contract typically runs roughly $4 to $8 or more in combined commissions, exchange fees, and regulatory charges. For traders placing dozens of round-turns a day, those costs compound quickly.
Inactivity Fees
Some brokers charge a monthly fee if your trading volume or balance falls below a threshold. These inactivity fees commonly run around $10 per month and are often waived once you meet minimum activity levels.9TradeStation. Service Fees Not every broker charges one, so check the fee schedule before you open an account.
The Bid-Ask Spread
Beyond listed fees, every trade carries an implicit cost in the price itself. The bid is the highest price a buyer will pay; the ask is the lowest price a seller will accept. The gap is a cost you absorb when entering or exiting.
For heavily traded contracts, that gap is tight. The E-mini S&P 500 typically trades with a spread of 0.25 index points, one tick, worth $12.50 per contract. Buy at the ask and later sell at the bid, and you’ve already given up $12.50 before commissions. Less liquid contracts have wider spreads, which can make entry and exit considerably more expensive. The cost applies on both legs of a round-turn.
Platform and Market Data Subscriptions
Access to the market itself carries ongoing overhead. Trading platforms often charge a monthly subscription, ranging from around $30 to over $200 depending on features. Some brokers waive the platform fee if you hit a monthly trading-volume threshold.
Real-time price data is a separate line. CME Group’s fee schedule shows non-professional subscribers paying $1.50 per month for basic top-of-book data from a single exchange, or $11.35 for full depth-of-market data. A bundle covering all four CME Group exchanges (CME, CBOT, NYMEX, COMEX) runs $4.50 for top-of-book or $34.25 for depth-of-market. Professional subscribers pay substantially more; the listed real-time device fee is $125.75.10CME Group. CME Group Market Data Fee List
The non-professional rate isn’t just a volume category. You’re classified as professional if you work for a financial institution, are registered with any securities or commodities regulator, manage money for others, or use the data for any commercial purpose, among other criteria. Even someone employed at a bank in an unrelated role is classified as professional. If none of that applies and you trade only for your own account, you typically qualify as non-professional.
Rollover and Delivery
Most traders close positions before expiration, but contracts on physical commodities like crude oil, gold, or agricultural products can produce actual delivery obligations if held through the final trading day. Delivery means paying for storage, insurance, and transportation (carrying charges), which is a central reason most speculators exit well before expiration.
Even without delivery, keeping a position open across contract months has a cost. When the current contract nears expiration, you roll by closing the expiring contract and opening the same position in the next month. Each leg incurs the full set of commissions, exchange fees, and the bid-ask spread, so a roll effectively doubles your per-trade transaction costs. Some brokers offer discounted commissions on the calendar spread order used to roll, but exchange and regulatory fees still apply on both sides.
Financially settled contracts like the E-mini S&P 500 don’t involve physical delivery. At expiration, the clearinghouse credits or debits the cash difference based on the final settlement price. Rollover transaction costs still apply if you want continuous exposure.
What a Margin Call Can Cost
Once a position is open, your account equity has to stay above the maintenance margin. If the market moves against you and your balance drops below that line, you’ll get a margin call demanding you deposit enough to bring the account back to the initial margin level. ICE Futures rules give customers fewer than five business days to meet a call, counted from the day the account became undermargined.11ICE Futures US, Inc. Margin Rules
In practice, brokers often demand faster action, sometimes within hours, especially on leveraged day-trading accounts. If you don’t meet the call, your broker can liquidate positions without further notice. Some brokers add a flat fee on top of the trading loss. One major brokerage charges $75 per margin or risk liquidation on futures accounts.9TradeStation. Service Fees
Taxes on Futures Gains
Futures get distinct tax treatment under federal law. Under Section 1256 of the Internal Revenue Code, gains and losses on regulated futures contracts are automatically split 60% long-term and 40% short-term capital gains, regardless of how long you held the position.12Office of the Law Revision Counsel. 26 USC 1256 – Section 1256 Contracts Marked to Market The split applies even to a trade opened and closed the same day.
The practical effect is a lower blended rate for active traders. For 2026, the top federal rate on long-term capital gains is 20%, while short-term gains are taxed as ordinary income at rates up to 37%.13IRS. IRS Releases Tax Inflation Adjustments for Tax Year 2026 A futures trader in the top bracket effectively pays a blended rate of about 26.8% on gains (60% × 20% + 40% × 37%), compared to the full 37% a stock day-trader would owe on identical short-term profits.
Section 1256 contracts are also marked to market at year end. If you’re still holding an open position on December 31, the IRS treats it as if you sold and immediately repurchased it at fair market value on the last business day of the year. Unrealized gains or losses are reported on Form 6781 and taxed that year under the same 60/40 rule.14IRS. Form 6781 – Gains and Losses From Section 1256 Contracts and Straddles You can’t defer gains by simply holding into the next calendar year, so plan for a tax bill on paper profits you haven’t actually banked.
