What Is Net Profit Margin?
Net profit margin is the percentage of revenue that remains as net profit after deducting all business costs and expenses: cost of goods sold (COGS), operating expenses (rent, salaries, utilities), financial expenses, and taxes on profit.
Net Margin (%) = (Net Profit ÷ Net Sales Revenue) × 100
It's the most complete profitability indicator. A company might have a 50% gross margin, but if operating expenses are high, the net margin could be 3% or even negative.
How to Calculate Net Profit Margin Step by Step
-
Calculate Net Revenue
Gross revenue − returns − discounts given − sales taxes (such as VAT and other sales taxes). -
Subtract COGS
Cost of goods or services sold in the period. Result = Gross Profit. -
Subtract Operating Expenses
Rent, salaries, benefits, utilities, internet, marketing, depreciation. Result = Operating Profit. -
Account for Financial Income and Expenses
Interest paid on loans, returns on investments. Result = Profit Before Tax. -
Subtract Income Tax
Final result = Net Profit. -
Calculate Net Margin
Net Margin = Net Profit ÷ Net Revenue × 100.
