Understanding Margins Across Commerce, Stocks, and Forex
The term "margin" carries different meanings across business commerce, equity brokerage, and currency trading. Understanding these distinctions is crucial for profitable pricing and disciplined risk management.
Margin vs. Markup in Retail
Profit Margin measures the percentage of final selling revenue that is pure profit ($P/R$), whereas Markup measures the percentage by which the cost price is increased to reach selling price ($P/C$). A 50% markup equals a 33.3% gross margin.
Stock Buying Power & Regulation T
In US equities under Federal Reserve Regulation T, standard margin requires 50% initial equity, granting 2:1 purchasing power. FINRA requires a minimum 25% maintenance margin; falling below triggers a mandatory margin call.
Forex Leverage & Required Margin
In currency trading, brokers offer high leverage (e.g. 20:1, 50:1, or 100:1), requiring only 1% to 5% collateral deposit to control large notional positions. Leverage magnifies both potential gains and rapid liquidation risks.

Margin Calculator — Frequently Asked Questions
Q1 What is the difference between Profit Margin and Markup? ▾
Profit Margin is the percentage of selling revenue that is profit ((Revenue - Cost) / Revenue × 100), whereas Markup is the percentage added onto the initial cost price to reach the selling price ((Revenue - Cost) / Cost × 100). For example, a 50% markup yields a 33.33% margin.
Q2 How do stock margin requirements work under Regulation T? ▾
Under US Federal Reserve Regulation T, the initial margin requirement for buying equities is 50%, meaning you must provide at least half of the total purchase value in cash or marginable securities. FINRA also mandates a 25% minimum maintenance margin.
Q3 What is a Margin Call and how is it triggered? ▾
A margin call occurs when account equity drops below the broker's maintenance margin threshold due to adverse stock price movements. The investor must immediately deposit additional funds or close securities to restore required equity levels.
Q4 How is Forex required margin calculated from leverage? ▾
Forex required margin represents the collateral deposit necessary to open a leveraged position. It equals Total Notional Value divided by the Leverage Ratio (e.g. at 50:1 leverage, you only deposit 1/50th or 2% of the trade's total value).
Q5 Can margin be negative or 100%? ▾
A 100% margin occurs if an item has zero cost ($0 cost, $100 revenue = 100% margin). A negative margin occurs if an item is sold below cost (at a loss), resulting in negative profit.
