Futures Margin & Leverage Calculator
See the true leverage of a futures trade: enter price, contract multiplier and initial margin to get notional value, effective leverage and margin percentage.
How it works
Notional = price × multiplier × contracts · Leverage = notional ÷ total margin · Margin % = total margin ÷ notional × 100
Futures are inherently leveraged: you post an initial margin that is a small slice of the contract’s notional value, and your effective leverage is the notional divided by that margin. High leverage magnifies both gains and losses on the same price move, and if losses erode your margin below the maintenance level the broker issues a margin call. Knowing the ratio up front keeps position sizing honest.
Worked example
One E-mini S&P 500 contract at 5,000 points with a $50 multiplier has a notional value of 5,000 × $50 = $250,000. On $12,000 of initial margin that is 250,000 ÷ 12,000 = 20.8:1 leverage, or a 4.8% margin.
Frequently asked questions
What is a contract multiplier?
The multiplier converts each point of the contract’s price into dollars. The E-mini S&P 500 uses $50 per index point, so a one-point move changes the contract value by $50.
What is the difference between initial and maintenance margin?
Initial margin is what you post to open a position; maintenance margin is the lower balance you must keep. If your equity falls below maintenance, you get a margin call to top up or the position is liquidated.
Is 20:1 leverage risky?
It means a 5% adverse move in the underlying wipes out your entire margin. Leverage does not change the odds of a price move, but it makes each move a much larger fraction of your capital, so most traders use only part of the maximum available.
