Gross Margin
Gross margin is gross profit expressed as a percentage of revenue after subtracting cost of goods sold or cost of revenue under a defined accounting policy.
The formula is simple, but the classification of direct costs can vary by accounting framework and business model. Gross margin is not contribution margin or net margin.
Calculate gross profit as revenue minus COGS or cost of revenue, then divide gross profit by revenue. Use consistent classifications and handle zero or negative revenue with care.
Move from revenue to gross profit and margin
Classification determines what is subtracted before the percentage is calculated.
Costs classified under the applicable policy
Revenue less the classified cost
Multiply by 100 to express gross margin as a percentage.
What is Gross Margin?
Gross margin measures the share of revenue remaining after cost of goods sold or cost of revenue is subtracted. Gross profit is the currency amount. Gross margin is that amount divided by revenue and expressed as a percentage.
What belongs in COGS or cost of revenue depends on the business model, accounting framework, and consistently applied policy. A manufacturer may include inventory costs assigned to goods sold. A service or software company may use cost of revenue for selected delivery costs. Employee, hosting, support, payment-processing, freight, or other costs are not classified universally.
Gross margin can help explain changes in pricing, mix, delivery cost, or production economics, but it does not show all operating expenses, financing, taxes, or cash movement.
Gross Margin versus gross profit
Gross profit is an amount: revenue minus COGS or cost of revenue. Gross margin expresses gross profit as a share of revenue. A company can increase gross profit while its gross margin falls if revenue grows with a less favorable cost mix.
Gross Margin versus contribution margin
Contribution margin commonly subtracts variable costs defined for a particular decision, product, or unit analysis. It may include costs that are not classified as COGS, or exclude costs that accounting includes there. State the contribution policy before comparing it with gross margin.
Gross Margin versus net margin
Net margin reflects net income as a percentage of revenue after the wider set of expenses, interest, taxes, and other applicable items. Strong gross margin can coexist with a net loss when operating and other costs exceed gross profit.
Classification and comparability
A margin trend is only as comparable as its revenue and cost classifications. Reclassifications, acquisitions, channel mix, currency, refunds, and revenue-recognition changes can affect the result. Reconcile policy changes before interpreting the trend.
Why it matters
Gross margin helps a business understand how much reported revenue remains after the cost assigned to delivery. It can support pricing, product mix, supplier, capacity, and operating-plan discussions.
There is no universal good margin for every industry or company. Business model, stage, mix, accounting policy, and strategic choices all affect the result. Use relevant context rather than applying an unsupported benchmark.
Gross margin formulas
Gross Profit = Revenue - COGS or Cost of Revenue Gross Margin % = Gross Profit / Revenue x 100
Illustrative gross margin
A business reports $200,000 of revenue and $70,000 of cost of revenue under its approved policy. Gross profit is $130,000, and gross margin is 65%.
If the business later reclassifies a delivery cost between operating expense and cost of revenue, it should restate or reconcile the comparison before attributing the margin change to operations.
How RunwayCal helps
