How this is calculated
Notional position size equals lot size times 100,000 units, converted to USD using the exchange rate you enter.
Broker margin required equals notional position size divided by your broker's leverage. This is the bare minimum your broker requires to open the position.
Minimum account size equals margin required divided by your own target usage percentage. Choosing a smaller target percentage, meaning you want this one trade to use less of your account, raises the account size this tool recommends.
Margin requirements vary by broker and by currency pair, and cross pairs require conversion at the current exchange rate. This is a simplified, USD-based estimate.
Risk & liability disclaimer: This calculator performs simple arithmetic on the numbers you enter and does not pull live exchange rates or your actual broker's margin schedule. Actual margin requirements vary by broker, account type, and currency pair. This is not financial advice.

Forex trading involves substantial risk of loss, and leveraged trading can amplify losses beyond your initial margin in some account types.
Meeting the Margin Requirement Is Not the Same as Trading Responsibly
