How Forex Margin Works
Margin is the portion of your account balance your broker sets aside as collateral to open a leveraged position — it isn’t a fee, but it is capital you can’t use for other trades while the position is open. This margin calculator tells you exactly how much margin a position will require before you open it.
How leverage changes the margin required
Margin required is your position’s total value divided by your leverage ratio. At 1:100 leverage, a $100,000 position only needs $1,000 in margin; at 1:500, the same position needs just $200. Higher leverage frees up more of your balance for other trades, but it also means a smaller adverse price move can trigger a margin call.
Avoiding a margin call
Knowing your required margin in advance lets you keep enough free margin in your account to absorb normal price fluctuation without your broker automatically closing positions. Checking this before every trade, not just when opening your account, is good practice as position sizes change.
