Arithmetic on the leverage shown. Broker and regulatory margin requirements differ by instrument and jurisdiction.
How it works
Margin is the part of a position's value that has to be set aside to open it with leverage. The notional value of a position is its size multiplied by its price; divide that by the leverage and the result is the margin required. At 30:1, margin is about 3.33% of the position's value; at 10:1 it is 10%.
For a forex position the notional is naturally expressed in the base currency — one lot of EUR/USD is 100,000 euros — and in the quote currency after multiplying by the price. Kinzan shows the margin in the quote currency and converts it into the account currency with a live rate from its board.
Margin requirements are set by each broker and, in many jurisdictions, capped by regulators for retail clients at different levels for different asset classes. Treat the result as arithmetic on the leverage entered, not as any broker's requirement.
Formula: Margin = (Units × Price) ÷ Leverage.
Questions
How is forex margin calculated?
Multiply the position size in units by the price to get the notional value, then divide by the leverage. One lot of EUR/USD at 1.1000 with 30:1 leverage needs about $3,667 of margin.
What is the difference between margin and leverage?
Leverage is the ratio of the position's value to the capital committed; margin is that committed capital. Higher leverage means lower margin for the same position.
Does lower margin mean lower risk?
No. Margin changes how much capital a position ties up, not how much it gains or loses for a given move. The same position has the same profit and loss at any leverage.
