How to read this result

  • What the required margin is

    The amount locked in your account to hold that position. It is the trade size divided by the leverage.

  • What the margin level is

    How many times your balance covers the required margin. The lower it is, the closer a stop-out becomes.

  • Points to watch

    The stop-out price is calculated at a 100% margin level. The actual level differs between brokers.

Method and specification

  • Main inputs used

    Currency pair / Lot size / Leverage / Current rate / Account balance

  • When to use it

    Checking locked funds before entry / Checking headroom before adding positions

  • Notes

    Calculated at 1 lot = 100,000 units (100 ounces for gold). The margin your broker actually requires may differ.

Frequently Asked Questions

How is the required margin calculated?

It is trade size divided by leverage. Trade size is lot size x contract size (normally 100,000 units, or 100 ounces for gold) x rate. For example, trading one lot of USD/JPY at a rate of 150 with 1:25 leverage gives a trade size of 100,000 units x 150 = 15,000,000 JPY, not 1,000,000 units, so the required margin is 600,000 JPY.

What margin level should I keep?

Margin level is account balance divided by required margin x 100. Many Japanese brokers close positions once it falls below 100%. To absorb open losses and sudden moves, many traders keep 300-500% or more in practice, and the more headroom you keep, the further price can travel before a stop-out.

Does higher leverage make losses bigger?

Leverage itself only lowers the margin required; what decides the size of your profit or loss is the lot size. That said, needing less margin makes it easier to open a large lot, which is how losses end up growing. It is safer to decide the loss amount first with the lot calculator.
