❓ FAQ
What is the difference between margin and markup?+
Margin is profit as a % of the selling price: (Profit ÷ Revenue) × 100. Markup is profit as a % of the cost: (Profit ÷ Cost) × 100. A 50% markup is NOT the same as a 50% margin — they use different bases.
How do I calculate gross margin?+
Gross Margin % = ((Revenue - COGS) ÷ Revenue) × 100. For a product costing $60 sold at $100: GM = ((100-60) ÷ 100) × 100 = 40%.
What is a good profit margin?+
Varies by industry. Retail: 2–10% net margin. Software/SaaS: 60–80% gross margin. Restaurants: 3–9% net. Professional services: 15–40% net. Gross margins above 50% are generally considered strong across most industries.
What is COGS?+
COGS (Cost of Goods Sold) is the direct cost of producing the goods or services sold. It includes materials, direct labour and manufacturing overhead but excludes operating expenses like marketing and admin.
How do I convert markup to margin?+
Margin = Markup ÷ (1 + Markup/100) × 100. For a 66.67% markup: Margin = 66.67 ÷ 1.6667 = 40%. A 100% markup equals a 50% margin. Use the Markup → Margin tab for instant conversion.
