Find out how much margin you need to open a position at your chosen leverage, so you never over-leverage or run out of free margin.
Works with any broker and platform, including MetaTrader 4 (MT4), MetaTrader 5 (MT5), cTrader, NinjaTrader, TradingView, DXtrade and Match-Trader.
Margin is the deposit your broker holds to keep a leveraged position open. Higher leverage means less margin required, but the same risk on the underlying position. This calculator shows both the full notional value you control and the margin locked up.
Required margin = (lot size × contract size × price) ÷ leverage. One lot of EUR/USD at 1.10 with 1:100 leverage needs $110,000 ÷ 100 = $1,100 of margin. Forex contract size is usually 100,000 units per lot; gold is often 100 ounces.

Start free trialMultiply the lot size by the contract size and the current price to get the notional value, then divide by your leverage. One lot of EUR/USD at 1.10 with 1:100 leverage requires $1,100 margin.
Leverage does not change your risk on a given position size, only the margin required. Many EU and UK regulated brokers cap retail leverage at 1:30, while offshore brokers offer 1:500 or more. Trade the position size your risk allows, not the maximum leverage available.
A margin call happens when your account equity falls too close to the margin required to hold your open trades. The broker may close positions automatically. Keeping plenty of free margin avoids this.
