Frequently Asked Questions
What is gross profit margin?
Gross Profit Margin = (Revenue − COGS) ÷ Revenue × 100. COGS (Cost of Goods Sold) includes direct costs: materials, manufacturing, and direct labour. It excludes operating expenses like rent, salaries, and marketing. Example: Revenue ₹1,00,000, COGS ₹60,000 → Gross Margin = 40%.
What is net profit margin?
Net Profit Margin = Net Profit ÷ Revenue × 100. Net profit = Revenue − All expenses (COGS + operating expenses + taxes + interest). It shows what percentage of revenue becomes actual profit. A healthy net margin varies: retail 2–5%, SaaS 20–40%, professional services 15–25%.
What is a good profit margin?
It depends heavily on industry. Grocery retail: 1–3%. Restaurants: 3–9%. E-commerce: 5–15%. Software/SaaS: 20–40%. Consulting: 30–50%. Compare against competitors in your sector, not cross-industry averages.
What is the difference between profit margin and markup?
Profit margin is calculated as a percentage of revenue (selling price). Markup is calculated as a percentage of cost. Same product: Cost ₹80, Sell ₹100. Margin = (20÷100)×100 = 20%. Markup = (20÷80)×100 = 25%. Markup is always higher than margin for the same dollar profit.
How do I improve profit margin?
Increase revenue (raise prices, increase volume, upsell). Reduce COGS (negotiate supplier prices, reduce waste, optimise production). Reduce operating expenses (automate, reduce overhead). Improve product mix (sell more high-margin items). Even a 5% improvement in margin can double profit on thin-margin businesses.
