Margin Calculator
Calculate how much of your account a position will lock up as margin, essential for understanding how many trades you can run at once under a given leverage.
Position details
How this Margin calculator works
- Enter your account balance and currency (USD by default).
- Pick the instrument you trade and enter your position size in lots (standard, mini or micro; they stay in sync, so editing one updates the others).
- Enter your entry price (pre-filled with the current market price for built-in instruments) and the leverage your broker or challenge offers (e.g. 1:30 means a $1,000 position only ties up about $33 of your account).
- The calculator works out the notional value of the position (lots × contract size × price), then divides by leverage to get the required margin: the amount of your account that gets locked up to hold the trade.
- It also shows that margin as a % of your account balance, and the "free margin" left over for other trades or to absorb losses.
Why it matters for challenge-fit
Buy the wrong challenge and you can't open the positions you normally trade.
A 1 lot EUR/USD position at 1:100 requires $1,000 margin. At 1:10, that same lot requires $10,000. On a $5,000 account, you can't even open it.
Enter your position and leverage to see which challenges actually let you trade the size you want without hitting a margin limit.
