The Formula

Net Profit = Total Revenue - COGS - Operating Expenses - Interest & Taxes

Net Profit Margin (%) = (Net Profit ÷ Total Revenue) × 100%

Worked Example

500,000 Total Revenue, 200,000 COGS, 150,000 OpEx, 50,000 Interest & Taxes.

• Net Profit: 500,000 - 200,000 - 150,000 - 50,000 = 100,

000.

• Net Profit Margin: (100,000 ÷ 500,000) × 100 = 20.00%.

Understanding Your Result

Gross margin and markup are different: 50% markup = 33% gross margin. Pricing strategy varies by industry: SaaS software targets 70–85% gross margins; e-commerce typically 30–50%; professional services 50–70%; retail 25–50%; restaurants 60–75% (gross food cost margin). A gross margin below your industry average signals pricing pressure or high COGS — investigate before scaling. Contribution margin (revenue minus variable costs only) is the more useful metric for short-term pricing and production decisions.
