The maths
Notional (USD) = lots x contract size x base-to-USD rate Margin = notional / leverage
Margin is not a cost. It is the part of your balance the broker holds while the position is open, and it is released when you close.
Worked example
One standard lot of EUR/USD at 1.0850 is 108,500 USD of exposure. At 1:100 leverage the margin held is 1,085 USD.
Is margin a fee?
No. It is held, not spent. Costs on a position are the spread, the commission and any overnight swap.
What happens when free margin runs out?
The broker issues a margin call and, below its stop-out level, starts closing positions. The thresholds are set by the broker, not by the market.
Does the requirement move while the trade is open?
Brokers differ. Most hold the amount calculated at the open, while unrealised profit and loss move your free margin rather than the requirement itself.
