Margin Calculator

Required margin to open a position, by instrument, lot size and leverage. Uses measured contract sizes and live prices.

Margin ≈ (lots × contract size × price) ÷ leverage, in USD. Actual margin can vary with the broker's margin mode and tier rules; use a broker page for exact figures.

Frequently asked questions

How does the Margin Calculator work?
The Margin Calculator uses real, measured contract sizes per instrument, so the result matches what your MetaTrader terminal shows for that broker.
Are the contract sizes accurate?
Yes — contract sizes are measured directly from broker servers and are broker-invariant, verified against live accounts.
