Calculate profit margin, markup, and selling price
Profit margin is a profitability ratio that measures how much profit you make for every dollar of sales. It's expressed as a percentage of the selling price. A higher profit margin indicates that you're keeping more of each dollar earned as profit.
Markup is the amount added to the cost of a product to determine its selling price. It's expressed as a percentage of the cost. Markup helps businesses cover operating expenses and generate profit.

Margin is profit as a percentage of selling price, while markup is profit as a percentage of cost. For example, if something costs $50 and sells for $100: the margin is 50% (profit/price = $50/$100) but the markup is 100% (profit/cost = $50/$50). Margin can never exceed 100%, but markup can be any percentage.
To find selling price from cost and desired margin, use this formula: Selling Price = Cost / (1 - Margin%). For example, if your cost is $50 and you want a 40% margin: Price = $50 / (1 - 0.40) = $50 / 0.60 = $83.33. This ensures your profit is 40% of the selling price.
A "good" profit margin varies by industry. Software companies often have 70-90% gross margins, while grocery stores operate on 1-3% net margins. Generally, a net profit margin of 10% is considered average, 20% is good, and anything above 20% is excellent. However, always compare your margins to industry benchmarks for accurate assessment.
No, you cannot have a 100% profit margin because that would mean your entire selling price is profit with zero cost, which is impossible. The maximum theoretical margin approaches 100% as costs approach zero. However, you CAN have a 100% markup, which means you're doubling your cost (e.g., cost $50, sell for $100 = 100% markup but only 50% margin).
To convert markup to margin, use this formula: Margin% = (Markup% / (100 + Markup%)) × 100. For example, a 50% markup converts to: (50 / (100 + 50)) × 100 = (50 / 150) × 100 = 33.3% margin. To convert margin to markup: Markup% = (Margin% / (100 - Margin%)) × 100.
Both are useful, but for different purposes. Use markup when setting prices (easier to calculate: cost × markup = price). Use margin when analyzing profitability and comparing to industry standards (shows what percentage of each sale is profit). Many retailers use markup for pricing but report margins to stakeholders. Understanding both helps you make better business decisions.
Gross margin only considers direct costs (cost of goods sold), while net margin includes all expenses (operating costs, taxes, interest, etc.). For example, if you sell a product for $100 with $40 direct cost, your gross margin is 60%. But after paying $30 in operating expenses, your net profit is $30, giving you a 30% net margin. Gross margin shows product profitability; net margin shows overall business profitability.
