Summary
The Forex Margin Required Calculator computes the collateral your broker locks when you open a trade. Enter the currency pair, lot size, leverage, and current exchange rate to get the exact margin in your account currency. Understanding required margin helps you avoid margin calls and manage free margin effectively.
How it works
- Select the currency pair (e.g., EUR/USD, GBP/JPY).
- Enter the lot size — 1 standard lot = 100,000 units of the base currency.
- Enter your broker leverage (e.g., 1:100).
- Enter the current exchange rate for the pair.
- If your account currency differs from the quote currency, enter the conversion rate.
- The calculator applies: Margin = (Lot Size x Contract Size x Rate) / Leverage, then converts to your account currency.
Use cases

- Calculate free margin remaining after opening multiple positions.
- Compare margin requirements across different leverage settings.
- Plan trade size to stay within safe margin utilization limits.
