Gross Margin

General

Gross Profit Margin

The percentage of revenue left after subtracting the direct cost of producing goods or services, before operating expenses, tax, or interest are deducted.

Definition

Gross margin measures what percentage of your revenue survives after paying for what it actually costs to produce or deliver a product or service. It excludes overhead like rent, marketing, and salaries that aren't tied directly to production, those get subtracted later to arrive at operating or net margin.

It's one of the fastest ways to gauge whether a business's core offering is fundamentally profitable before layering on the cost of running the company around it. A business with strong gross margin has room to absorb rising overhead; one with thin gross margin doesn't.

Formula

Gross Margin (%) = (Revenue − Cost of Goods Sold) / Revenue × 100

Worked Example

A company sells $500,000 worth of product in a quarter, with $320,000 in direct production costs.

  • Gross profit: $500,000 − $320,000 = $180,000
  • Gross margin: $180,000 / $500,000 × 100 = 36%

That means 36 cents of every dollar in revenue remains after covering direct production costs, before any overhead is subtracted.

Key Things to Know

  • Gross margin varies wildly by industry, so compare within sector. A 25% gross margin might be excellent for a grocery chain and alarming for a software company.
  • It doesn't account for fixed costs. Rent, salaries not tied to production, and marketing spend all come out after gross margin, in the move to operating margin.
  • Rising gross margin over time often signals pricing power or efficiency gains. A company improving gross margin is either raising prices, cutting production costs, or shifting toward higher-margin products.
  • Gross margin and markup are related but not identical. Markup is calculated on cost, gross margin is calculated on revenue, so the same numbers produce different percentages depending on which one you're asked for.
  • A high gross margin doesn't guarantee overall profitability. Heavy spending elsewhere in the business can still turn a strong gross margin into a net loss.

Frequently Asked Questions

What's the difference between gross margin and net margin?
Gross margin only subtracts the direct cost of producing what you sold, while net margin subtracts everything, operating expenses, interest, tax, marketing, on top of that. A business can have a healthy gross margin and still post a net loss if overhead is too high.
What counts as cost of goods sold?
Direct costs tied to producing what you sell, raw materials, manufacturing labor, and shipping for physical products, or hosting and support costs for software. Rent, marketing, and executive salaries don't count, those show up further down the income statement.
What's considered a good gross margin?
It varies enormously by industry. Software companies often run 70-90% gross margins since delivery costs are low, while grocery retailers often sit at 20-30% because inventory and logistics costs are high relative to sales price.
Can gross margin be negative?
Yes, if the direct cost of producing something exceeds what you sell it for. This happens with loss-leader pricing or early-stage products still working out production efficiency.
How does gross margin help with pricing decisions?
It shows how much room you have before a price cut eats into your actual production costs, not just your final profit. A product with 60% gross margin can absorb a discount much more comfortably than one sitting at 15%.
