Margin calculator

Margin is what your broker sets aside while a position is open. It is not what the position is worth, and it is not what you can lose — both of those are larger, and confusing them is how accounts disappear.

  1. Position value = 100,000 EUR × 1.00 lots × 1.16249 = $116,249.00.
  2. Margin = $116,249.00 ÷ 100 = $1,162.49.
  3. That is what is set aside, not what is at risk. The whole $116,249.00 moves with the market.

Prices shown are our last stored reading and are indicative only. Contract sizes follow the standard market conventions and are printed above the calculator; your account’s own specification is what applies to a real position. Nothing here is a recommendation.

The number that matters is the one underneath

A standard lot of EUR/USD at 1.0900 is a $109,000 position. At 100:1 leverage the margin is $1,090. Both figures are real, and the one people remember is the small one.

The whole $109,000 moves with the market. A 1% move against you — an ordinary day — is $1,090, which is the entire margin. This is what leverage does: it does not reduce your exposure, it reduces the deposit needed to take it.

Lower leverage on the same position size does not make you safer, because the position is identical; it only ties up more of your balance. What makes you safer is a smaller position.

Margin call and stop-out

As a position moves against you, your equity falls while the margin requirement stays roughly the same. The ratio between them is your margin level. Below a certain level you are warned; below a lower one, positions are closed automatically to stop the account going negative.

That automatic close happens at the market price at that moment, which in a fast market may be well past the level you expected. It is not a stop loss you chose, and it is not a protection you can rely on to preserve capital.

Common questions

Is margin a fee?
No. It is your own money, held aside while the position is open and released when it closes. What costs you money is the spread, any commission, and overnight financing.
Does higher leverage mean higher risk?
Not by itself. It permits a larger position on the same deposit, and it is the larger position that carries the risk. The same one lot behaves identically at 30:1 and 100:1; only the deposit differs.
What happens if my margin runs out?
Positions are closed automatically, starting with the largest loss, until the account is back above the required level. You do not choose which or at what price.
Why is USD/JPY margin the same at any price?
Because the dollar is the base currency: one lot is 100,000 US dollars by definition, so the position value does not move with the rate the way a EUR/USD position does.
