Margin calculations vary by context but all measure the relationship between cost, revenue, and profit, or the amount of capital required for leveraged trading.
Where:
• Cost = The amount spent to produce or acquire the product.
• Revenue = The total income from selling the product.
• Profit Margin = The percentage of each dollar that remains as profit.
• Markup = (Revenue − Cost) / Cost × 100%
Stock Margin Formula:
The amount you must invest = Total position value × Margin percentage. The remainder is borrowed from the broker.
Forex Margin Formula:
Leverage = 100 / Margin Ratio. A 2% margin ratio gives 50:1 leverage, meaning you control $50 of currency for every $1 of your own money.
M = (R - C) / R × 100%
Sreq = P × N × (MR / 100)
Freq = U × E × (MRfx / 100)
Profit Margin Example: A company buys a product for $40 (cost) and sells it for $100 (revenue).
For every dollar of revenue, the company keeps 60 cents as profit before other expenses.
Stock Margin Example: You want to buy 200 shares of a $100 stock with a 50% margin requirement.
You control $20,000 worth of stock with only $10,000 of your own money, effectively doubling your purchasing power — and your risk.
Forex Margin Example: Trading 100,000 units of EUR/USD at 1.20 exchange rate with 2% margin requirement.
With just $2,400, you control a $120,000 currency position. A 1% move in your favor doubles your investment, but a 1% against you wipes it out.
Tip: Higher leverage means higher potential returns AND higher potential losses. Always understand your risk tolerance before trading on margin.
