(revenue − cost of goods) ÷ revenue × 100.

Gross margin measures the share of revenue left after cost of goods sold: (revenue − cost of goods) ÷ revenue × 100. Revenue of 100,000 and cost of goods of 65,000 produce gross profit of 35,000 and a 35% gross margin. The calculator reports a percentage, not the currency amount of gross profit.

Margin and markup are different

Margin divides profit by selling revenue, while markup divides profit by cost. The same transaction therefore has different margin and markup percentages. Use the term required by the business decision and avoid substituting one for the other.

Define cost of goods consistently

Inventory accounting, direct labour, freight and manufacturing overhead may be treated differently across businesses. A comparison is meaningful only when revenue and cost of goods use the same period and accounting policy. Operating expenses are normally below gross profit, not inside this calculation.

Interpret movement, not just the level

Compare margin across consistent periods and investigate changes in price, product mix, purchasing cost, discounts, returns and wastage. A rising revenue total can coexist with a falling margin if lower-margin products or discounting drive the growth.

Interpretation checklist

  • Match revenue and costs to the same period.
  • Exclude sales taxes collected for authorities.
  • Use a consistent cost classification.
  • Review gross profit amount with the percentage.

Continue the analysis with calculate required unit sales, review broader profitability, compare investment return, and track margin movement. These tools answer different parts of the decision and should not be treated as interchangeable results.

For product-level analysis, calculate margin using revenue and cost attributable to the same product. Company-wide overhead should not be allocated inconsistently merely to improve one product figure. A stable definition makes margins useful for pricing, sourcing and product-mix decisions.

Retain the underlying gross-profit amount so the commercial scale of every percentage movement remains visible.

Questions people ask about Gross Margin Calculator

Is gross margin the same as net profit margin?

No. Gross margin excludes operating, financing and tax expenses.

Can margin exceed 100%?

Not under ordinary positive revenue and cost inputs.

Why can markup be higher than margin?

Markup uses cost as the denominator, while margin uses the higher selling revenue.

Should discounts reduce revenue?

Use net revenue after discounts and returns when that matches the accounting comparison.
