Formula Explained – How Profit Margin is Calculated
Our profit margin calculator uses the exact industry-standard formulas trusted by accountants worldwide:
Gross Profit Margin Formula
Gross Profit Margin = ((Revenue − COGS) / Revenue) × 100
- Measures how efficiently you produce or deliver your product/service
- Ignores operating expenses, taxes, and interest
- Ideal for comparing product lines or manufacturing efficiency
Net Profit Margin Formula
Net Profit Margin = ((Revenue − COGS − Operating Expenses) / Revenue) × 100
- The “bottom line” — true profitability after ALL costs
- Includes rent, salaries, marketing, taxes, utilities, etc.
- The most important metric for overall business health
Real Example Breakdown (Net Profit Margin)
Revenue: $10,000
COGS: $6,000 → Gross Profit = $4,000
Expenses: $2,000 → Total Costs = $8,000
Net Profit = $2,000
Net Profit Margin = ($2,000 / $10,000) × 100 = 20%
