Definition
Gross profit is revenue minus the cost of goods sold. It shows how much a business earns from its products before operating expenses, interest and tax. Expressed as a percentage of revenue it becomes the gross margin, a key measure of pricing power and production or purchasing efficiency.
How it works
Gross profit sits near the top of an income statement presented by function, between cost of sales and operating expenses. A falling gross margin usually means rising purchase costs, discounting or a shift in sales mix toward cheaper products.
Gross margin is not the same as markup: a product bought for 60 and sold for 100 has a 40% gross margin but a 66.7% markup on cost. Use the margin and markup calculator to convert between the two. Gross profit also differs from contribution margin, which deducts all variable costs, including variable selling costs, and excludes fixed production overhead.
Formula
Gross profit = Revenue - Cost of goods sold
Gross margin % = Gross profit / Revenue × 100
Example: gross margin of an online shop
An online shop sells 250,000 of goods in a year. The goods cost 160,000 including inbound freight. Gross profit is 90,000 and the gross margin is 90,000 / 250,000 = 36%. Out of every 100 of sales, 36 is left to pay staff, rent, marketing and tax.
