Reference & details

How it works

Gross Profit Margin

Gross margin measures profit as a percentage of revenue. It shows how much of each dollar of sales is retained after direct costs.

Gross Margin % = ((Revenue − Cost) ÷ Revenue) × 100

Profit Amount

The absolute profit is the difference between what you sold for and what it cost to produce or acquire.

Profit = Revenue − Cost

Scope of the Result

This is a gross product or transaction margin based only on the revenue and direct cost entered. Operating expenses, returns, tax, payment fees, financing, and allocation choices can materially change net profitability.

Markup % = Profit ÷ Cost × 100 (undefined when cost is zero)

Example Scenarios

An online seller analyzes gross margin on a product sold for $79 with $32 cost of goods.

Revenue: $79Cost: $32

Profit: $47, margin: 59.5%

A software company calculates gross margin on a monthly subscription with minimal delivery cost.

Revenue: $99Cost: $12

Profit: $87, margin: 87.9%

A seller tests a discounted price equal to or below direct cost and confirms that the calculator reports break-even or a negative margin instead of a positive industry label.

Common Mistakes to Avoid

Using markup percentage as margin percentage

A product with 100% markup has only 50% margin. Markup divides by cost; margin divides by revenue. Convert between them before comparing.

Ignoring operating expenses in margin analysis

Gross margin excludes rent, salaries, and marketing. A 60% gross margin product can still be unprofitable if operating costs exceed 60% of revenue.

FAQ

The arithmetic follows gross margin = (revenue − direct cost) ÷ revenue. The result is only as complete as the costs entered and should not be treated as net margin, tax advice, or an industry benchmark.
