Margin is an amount; a ratio needs a denominator
Futures margin and leverage describe related but different things. In CME’s futures education, margin is money deposited and kept with a broker for an open position. A leverage comparison relates exposure to a named amount of funds. Before reading “10 times” as a useful number, ask: ten times which amount?
Separate the contract’s notional, the margin required, the funds actually posted and the account-equity figure used in the comparison. Dividing notional by posted funds answers a different question from dividing it by account equity. Neither calculation tells you the required margin unless that requirement is separately supplied.
Name notional, required margin, posted funds and equity
Notional describes the exposure value of a contract. It is distinct from the funds put up as margin. CME’s FAQ illustrates notional with a contract value factor multiplied by an index level. We use only that distinction here and stipulate a notional directly; we do not apply one notional formula to every futures contract.
CME distinguishes futures margin from money borrowed to buy securities. In its conventional futures explanation, the deposit is not a purchase down payment and does not give you ownership of the underlying commodity. That distinction does not settle the financing arrangements of every product. The separate guide to product rights and obligations explains why the instrument matters.
The following labels will stay separate throughout our fictional example. All amounts use the same illustrative currency unit, CU. Account equity is an explicitly chosen input, not a balance-sheet formula derived here.
| Amount | Role in this guide | Fictional input or limit |
|---|---|---|
| Notional, N | Exposure-value amount | 1,000 CU, stipulated |
| Required margin | Amount specified by the applicable requirements | No numerical requirement is stipulated or calculated |
| Posted amount, C | Funds put up in the illustration | 100 CU, not a verified required minimum |
| Account equity, E | Separately stipulated account amount | 100 or 200 CU; no account-equity formula is assumed |
In particular, the posted 100 CU is not a claim that 100 CU would satisfy a real requirement. Nor does posting 100 CU establish that the whole account’s equity is 100 CU.
Keep notional fixed, then change the denominator
Compare two invented alternatives at one instant. Both have notional N of 1,000 CU and posted funds C of 100 CU. Alternative A has stipulated account equity E of 100 CU; alternative B has E of 200 CU. These are alternative account states, not consecutive steps in a trade.
| Alternative | Notional N (CU) | Posted C (CU) | Stipulated equity E (CU) | N ÷ C | N ÷ E |
|---|---|---|---|---|---|
| A | 1,000 | 100 | 100 | 10 | 10 |
| B | 1,000 | 100 | 200 | 10 | 5 |
Notional divided by posted funds is 1,000 ÷ 100 = 10 in both rows. Notional divided by stipulated equity is also 10 in A, but 1,000 ÷ 200 = 5 in B. Each ratio is dimensionless because the numerator and denominator use the same currency unit.
The exposure has not changed between these alternatives. The account-equity input has. That is why you need the denominator’s name beside the ratio. We are not declaring either ratio to be the single official definition of leverage, or using E as a universal account-equity calculation.
The required margin is still unknown in both rows. The arithmetic does not supply a missing requirement or show that either account is sufficiently funded.
A requirement is different from a changing balance
CME’s lesson describes initial margin as the funds required by CME Clearing to initiate a futures position. It also notes that a broker may collect additional funds. A clearing requirement and the amount a customer is asked to provide should therefore keep their own labels.
In CME’s FAQ, performance bonds are deposits held at CME Clearing to help ensure clearing members can meet their obligations to customers and to CME Clearing. Requirements vary by product and market volatility. The FAQ distinguishes initial margin from maintenance margin, the minimum level to be maintained in the account, and describes a call to restore initial margin when margin equity falls below maintenance.
The FAQ also describes account balances being debited or credited as futures prices change. These explanations give context for requirements and balances; they are not a current broker rulebook. They do not establish a universal threshold, call deadline or automatic-liquidation sequence for every account.
These ratios do not calculate the loss or liquidation price
A ratio of 10 or 5 is not a recommended leverage level. Our two rows contain no price path, profit or loss, fees, cash flows, maintenance threshold or broker configuration. They cannot establish a maximum loss, liquidation price, suitable position size or entitlement to trade.
Those are different questions from naming an amount. For the distinction between planned price distances, costs and account risk, see the risk–reward guide’s units and costs discussion. For a separate notional-based periodic payment, see the fictional funding-payment ledger. Neither task is performed by these margin ratios.
Common questions about futures margin and leverage
Is futures margin the same as a stock-margin loan?
Not in the distinction CME makes here. Its futures deposit supports obligations on a position; it is not a down payment that buys the underlying commodity. CME contrasts this with borrowing to buy securities. That comparison is not a statement that every derivative or financing arrangement is free of borrowing.
Are required margin and posted funds always the same amount?
They describe different roles: a requirement states what must be provided, while posted funds describe an amount put up. Our example supplies only the latter, 100 CU. It leaves the required amount unknown and makes no claim that the two match.
Why can the same notional produce 10 and 5?
Because the denominator differs. With notional of 1,000 CU, division by 100 CU gives 10, while division by 200 CU gives 5. State whether you are using posted funds or the separately stipulated account equity; “10 times” alone omits that choice.
Does posted margin tell me the maximum loss?
This illustration establishes no loss limit. It names amounts and divides them; it models no outcome, liquidation rule or cash flow. Do not read the posted 100 CU as a calculated maximum loss.
What is the difference between initial and maintenance margin?
In CME’s explanation, initial margin relates to opening the position, while maintenance margin is the level to be maintained in the account. Its FAQ describes a call to restore initial margin if margin equity falls below maintenance. You still need the applicable current requirements to assess a real account; this guide supplies no current threshold or liquidation timetable.

The texts were checked on 19 October 2026; that is a source-check date, not a publication date. We use their educational concepts, not current margin percentages, contract prices or a broker rulebook. All amounts in the two alternatives are invented. Required margin is left unspecified, and account equity is stipulated rather than derived from an account formula.
