Work out futures margin instantly with clear inputs, formula shown and shareable results.
Futures margin is a good-faith deposit against a much larger notional exposure. At 12% initial margin you control roughly eight times your capital, which magnifies both gains and losses on the full contract value.
Margin and leverage
Notional = price × lot size × lots; margin = notional × margin %; leverage = 1 / margin %
Figures are estimates for planning only. Market returns are not guaranteed, and rates, limits and tax rules change. This is not financial or tax advice — speak to a qualified adviser before acting.

Exchanges raise margin when volatility rises, which can force deleveraging exactly when markets are stressed.
