The percentage version of gross profit. Gross margin lets you compare profitability across periods and against industry peers in a way absolute dollar amounts can't.

Definition

Gross Margin - gross profit expressed as a percentage of revenue. Tells you how much of each dollar of sales is left after the direct cost of producing that sale.

Formula

Gross Margin = Gross Profit ÷ Revenue × 100%

Or: Gross Margin = (Revenue − COGS) ÷ Revenue × 100%

Common uses

Industry benchmarking - compare to direct peers
Trend monitoring - the single best early warning for margin compression
Pricing analysis - shows the impact of pricing changes on product economics

Watch out

A 2-3 point drift in gross margin over 6 months is rarely random. Diagnose the cause before the compression compounds.

Frequently asked questions

What's the difference between gross profit and gross margin?

Gross profit is a dollar amount; gross margin is the same number as a percentage of revenue. A business with $100K revenue and $40K gross profit has a 40% gross margin.

What's a healthy gross margin?

Depends entirely on industry. Software 70-85%, professional services 40-60%, retail 25-40%, grocery under 25%. Compare to industry, not absolute numbers.

What causes gross margin compression?

Input cost inflation, hidden discounting, customer mix shift (more lower-margin customers), vendor price increases, payment processing fees creeping up.

How often should I watch gross margin?

Monthly. Gross margin compression is one of the most reliable early warnings of structural trouble - catch it within 2-3 months.

Can gross margin be negative?

Yes - it means you're selling each unit for less than it costs to produce. An existential problem; no scale fixes it.

How is gross margin different from net margin?

Gross margin only subtracts direct production costs. Net margin subtracts everything (operating expenses, interest, taxes). Net is always smaller than gross.
