Why Profit Margin Matters
Revenue shows how much a business sells, but margin shows how much remains after the costs included in the calculation. Tracking margin helps compare products, customers, projects, channels, and periods even when their sales values differ.
Profit margin is usually profit divided by revenue, multiplied by 100. The meaning of profit must be stated. Gross margin uses direct cost of goods or services, operating margin includes operating expenses, and net margin includes a broader set of expenses according to the accounting definition used.
How Hemiley Calculates Profit Margin
Enter revenue and the relevant cost amount. Hemiley calculates profit as revenue minus cost and expresses that profit as a percentage of revenue.
Use consistent figures. Tax-inclusive versus tax-exclusive revenue, refunds, shipping, commissions, overhead allocation, depreciation, interest, and owner compensation can change the result. A margin based only on direct cost should not be labelled net margin.
