Margin calculator

Leverage lets you control a large position with a smaller deposit. This calculator shows how much margin you need to open a position of a given size at your chosen leverage.

Contract size · Pip size

These are typical standard values — they vary by broker and instrument, so confirm and adjust them to match your own account.

How to use it

  1. 1 Pick your instrument and enter the current price.
  2. 2 Enter your lot size and your leverage (e.g. 1:100).
  3. 3 Choose your account currency and, if needed, the conversion rate.
  4. 4 Read the required margin and the notional value of the position.

How the margin is calculated

Notional value (in the quote currency) = contract size × lots × price. Required margin = notional value ÷ leverage, converted to your account currency. Higher leverage means less margin — but the same exposure and risk.

Frequently asked questions

What is margin?

Margin is the deposit your broker sets aside to keep a leveraged position open. It is not a cost or a fee — it is returned when you close the position, adjusted for your profit or loss.

How does leverage affect the margin?

Margin is inversely proportional to leverage: at 1:100 you need 1% of the notional value; at 1:500, 0.2%. Leverage reduces the deposit required but does not reduce the risk of the full position size.

What is a margin call?

If your account equity falls too close to the required margin, your broker may issue a margin call or close positions automatically. Margin and stop-out levels vary by broker — check yours.
