How it is calculated

Margin = lots × contract size × price ÷ leverage. The margin is held while the position is open; it is not a fee.

1.00 × 100,000 × 1.1000 = 110,000.00110,000.00 ÷ 20 = 5,500.00

What to do next

Compare the margin with your free funds before sending the order.

If margin takes most of the balance, a small move against you leaves no room. Position size comes from the stop; margin only checks that the trade fits.

This page explains what a margin calculator shows. It helps you see what a position may hold aside before you open it.

What each input means

Margin is the part of your account set aside while a position is open. It is not a fee and it is not a loss. Your platform shows the required amount on the order ticket before you confirm.

Position size is the amount of the market you plan to control. Price is the current level shown on your chart or ticket. The margin rate comes from your platform and can differ between instruments, so check it there.

How to read the result

The result is the amount your account must hold aside for that position. It changes when the position size or the price changes. A larger position usually holds aside more.

It does not include spread, commission or swap. It does not show what happens if price gaps over a weekend. It cannot tell you your future profit or loss. Treat it as one input to your planning, not a forecast.

A common mistake

A common mistake is treating the margin figure as the most you can lose. Your loss depends on price movement and can exceed the amount held aside.
