Understanding trading margin calculator

Trading margin is capital required to support a position, not the profit margin on a sale. More leverage reduces the initial funds shown here without reducing the position's price exposure. Actual requirements can change during a trade, and a broker may require more funds than a simple percentage scenario.

Formula and calculation method

Position value = price × quantity. Required funds = position value × margin percentage. Illustrative leverage = 100 / margin percentage.

Unlike the existing business profit-margin tool, this estimates trading capital from a user-entered margin requirement. Exchange, broker, instrument and risk rules can change; this does not calculate SPAN/exposure margin or guarantee leverage.

Factors affecting your result

Unlike the existing business profit-margin tool, this estimates trading capital from a user-entered margin requirement. Exchange, broker, instrument and risk rules can change; this does not calculate SPAN/exposure margin or guarantee leverage.

Changing trade price per unit changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
