How to use this calculator
Formula:
Margin = (Lot size × Contract size) ÷ Leverage
For a standard lot (100,000 units) on a USD-quoted pair at 100:1 leverage, the margin is $1,000. At 50:1 it's $2,000. At 30:1 (EU regulated) it's $3,333.
Margin is not the same as risk. Margin is what the broker locks; risk depends on your stop-loss distance. A large position with a tight stop can have small risk despite high margin.
