Gross Profit vs Net Profit: What Is the Difference and Why Does It Matter?

Gross Profit

Gross profit is revenue minus the direct costs of producing goods or services — the cost of goods sold (COGS). It measures how efficiently a business produces its product or delivers its service before any overhead costs. Gross Profit = Revenue - Cost of Goods Sold. Gross profit margin = Gross Profit / Revenue x 100.

What Goes Into Cost of Goods Sold?

COGS includes the direct costs directly attributable to production: raw materials, direct labour, and direct overheads like factory costs. It does not include selling costs, administration, marketing, or financing costs. For a retailer, COGS is the purchase price of goods sold. For a manufacturer, it includes materials, production labour, and manufacturing overhead.

Net Profit

Net profit (also called the bottom line or profit after tax) is what remains after all costs — including COGS, operating expenses, interest, and tax — have been deducted from revenue. Net Profit = Revenue - All Costs (COGS + Operating Expenses + Interest + Tax). Net profit margin = Net Profit / Revenue x 100.

Why the Difference Matters

A high gross profit margin with a low net profit margin reveals that overhead costs are eating into profitability — a signal to look at operating expenses, headcount, or cost structure. A low gross margin suggests the core business model is challenged — either pricing is too low or production costs are too high. Analysing both margins together gives a far clearer picture than either one alone.

Other Profit Measures

EBIT (Earnings Before Interest and Tax) removes the effect of financing decisions and tax jurisdiction. EBITDA further removes depreciation and amortisation, giving a rough proxy for operating cash flow. These measures sit between gross and net profit on the income statement and are widely used in financial analysis, valuation, and covenant reporting.
