Margin & Leverage Calculator
See how much capital a position actually ties up. Enter the position size in units, the price, and your leverage to get the margin your broker locks and the full notional value you control.
1 standard lot = 100,000 units · 1 mini lot = 10,000 · 1 micro lot = 1,000. Margin and notional are expressed in the price's currency.
FAQ
How do I calculate required margin?
Required margin = position value ÷ leverage, where position value = units × price. A 100,000-unit EUR/USD position at 1.1000 with 100:1 leverage needs 110,000 ÷ 100 = $1,100 of margin.
What does leverage like 100:1 mean?
100:1 leverage lets you control a position 100× the size of the margin you put up — so 1% margin. Higher leverage frees up capital but magnifies both gains and losses.
What is notional or position value?
It's the full size of the position you control (units × price), not the cash you put down. Margin is only the deposit your broker locks to hold that position open.
