Gross Margin
Gross margin is the first profitability line and often the most informative. It describes the raw economics of the product before any overhead.
Why this matters for beginners
A low gross margin limits everything that follows. No amount of cost control below that line can turn thin product economics into strong profits.
Main explanation
Gross profit is revenue minus the cost of goods sold, which covers the direct costs of producing or delivering what was sold. Gross margin expresses that as a percentage of revenue.
Margins differ by business model, not by management quality. Supermarkets operate on low margins and high turnover, while software carries very high margins and different costs elsewhere.
The trend matters more than the level. A falling gross margin suggests rising input costs, discounting, or a shift towards lower-margin products.
Compare only within an industry, and check how the company defines cost of goods sold, since some include delivery or support costs while others do not.
Example using a real company
Revenue of 500 with cost of goods sold of 300 gives gross profit of 200 and a gross margin of forty percent.
- →Revenue 500, cost of goods 300, gross margin 40 percent.
- →The same revenue with cost of goods 420 gives a gross margin of 16 percent, leaving far less for overhead.
Common beginner mistakes
- ✕Comparing gross margins across unrelated industries.
- ✕Ignoring a steady decline because the absolute level still looks acceptable.
- ✕Assuming every company defines cost of goods sold the same way.
