Understanding Profit Margin and Markup
Profit margin and markup are related but distinct concepts essential for pricing strategy. Margin is profit as a percentage of revenue: (Revenue - Cost) / Revenue x 100. Markup is profit as a percentage of cost: (Revenue - Cost) / Cost x 100. For example, with $120 cost and $160 revenue, profit is $40. Margin = $40/$160 = 25%, while Markup = $40/$120 = 33.33%. The same dollar profit yields different percentages depending on the base. Margin answers "what percentage of my selling price is profit?" while markup answers "how much did I add above my cost?" Retailers often think in markup terms ("50% markup" means selling at 1.5x cost), but margin better reflects business viability since expenses are typically expressed as percentages of revenue. To achieve a target margin, use the formula: Price = Cost / (1 - Margin%). For 25% margin on $120 cost: $120 / 0.75 = $160. Our calculator displays both metrics simultaneously, eliminating confusion and enabling accurate pricing decisions. Use our Break-Even Calculator to determine the sales volume needed to cover all costs.
Stock Trading Margin Requirements
Stock trading margin allows investors to purchase securities by borrowing funds from a broker, amplifying both potential gains and losses. The margin requirement is the percentage of the total purchase value you must deposit as collateral. For example, with a 30% margin requirement, purchasing 100 shares at $18.30 per share requires $549 in your account. Broker, security, account, and jurisdiction rules can differ, so enter the requirement quoted by your platform and review the margin agreement before trading.

Currency Exchange Margin for Forex Trading
Forex margin uses leverage to control a currency position with a smaller deposit. The margin ratio determines how much currency exposure each unit of deposited capital supports. To calculate required margin, use (exchange rate x units) / leverage ratio. For example, buying 100 EUR at 1.30 USD/EUR with 20:1 leverage requires $6.50 of margin. Rules and available leverage vary by broker and jurisdiction, so use the ratio quoted for your account and treat this calculator as a planning estimate.
