Each margin gives insight into a different aspect of a business.
Gross Profit Margin Explained
Gross profit margin shows how efficiently a business produces or sells its products.
- Gross Profit Margin Formula
- Gross Profit Margin = (Gross Profit ÷ Revenue) × 100
- Where:
- Gross Profit = Revenue − Cost of Goods Sold (COGS)
- Revenue = Total sales income
Example: Gross Profit Margin
- Revenue = ₹50,000
- Cost of Goods Sold = ₹30,000
- Gross Profit = 50,000 − 30,000 = ₹20,000
- Gross Margin = (20,000 ÷ 50,000) × 100 = 40%
- The gross profit margin is 40%.
Net Profit Margin Explained
- Operating costs
- Rent
- Salaries
- Taxes
- Interest
Net-Profit Margin Formula
Net Profit Margin = (Net Profit ÷ Revenue) × 100
Example: Net Profit Margin
- Revenue = ₹50,000
- Total expenses = ₹42,000
- Net Profit = 50,000 − 42,000 = ₹8,000
- Net Margin = (8,000 ÷ 50,000) × 100 = 16%
- The net profit margin is 16%.
