The Margin Calculator is powered by Investing.comA Margin Calculator in forex is a tool that calculates how much money (margin) you need in your trading account to open and maintain a leveraged trade.
In forex, you usually trade with leverage, meaning you control a large position using a smaller amount of your own money.
What is margin?
Margin = the amount of money your broker locks as collateral for a trade.
Example:
Trade size = $100,000
Leverage = 100:1
Required margin:
100
100000
Result:
Margin required = $1,000
So you only need $1,000 to control a $100,000 position.
What does a Margin Calculator use?

currency pair
trade size (lot size)
