Gross margin

Also known as: margin, profit margin, gross profit margin

Definition

The percentage of revenue a business retains after subtracting the direct costs of producing its goods or services.

The ratio of gross profit to net sales, representing the percentage of each dollar of revenue that a company retains as gross profit.

Why it matters

Gross margin reveals the fundamental efficiency of a business model. However, founders must not treat gross margin as personal profit. For instance, a fifty percent margin on one hundred thousand dollars of revenue leaves fifty thousand dollars in gross profit, which must still cover operating expenses like rent, marketing, taxes, and founder salaries.

Formula

Gross Margin Percentage = ((Revenue - Cost of Goods Sold) / Revenue) * 100

Improvement tips

  • Track the cost of goods sold accurately by including all direct labor, materials, and hosting costs.
  • Review pricing structures periodically to ensure that rising supplier costs do not erode your gross margin.
  • Negotiate volume discounts with vendors or optimize internal workflows to lower the unit cost of production.

Common mistakes

  • Treating gross profit as personal disposable income before accounting for fixed operating expenses and taxes.
  • Confusing gross margin, which is a percentage, with gross profit, which is the absolute dollar value.
  • Underestimating the direct costs of delivery, such as credit card processing fees or cloud infrastructure usage.
