The Gross Margin formula
Gross Margin = (Revenue − COGS) ÷ Revenue × 100
Gross margin isolates the cost of goods sold from revenue, before overhead, marketing or other operating costs — the number most product-level pricing decisions are based on.
Example
$50,000 in revenue against $22,000 in cost of goods sold.
(($50,000 − $22,000) ÷ $50,000) × 100 = 56% gross margin
