About Profit Margin Calculator (Gross & Net)

The Profit Margin Calculator calculates key business profitability metrics: Gross Margin (revenue minus COGS), Operating Margin (operating income), and Net Margin (bottom line net profit after all taxes and interest).

Formula & Mathematical Calculation

Gross Profit Margin (%) = [ ( Revenue - Cost of Goods Sold (COGS) ) / Revenue ] × 100

Net Profit Margin (%) = [ ( Net Profit after Taxes ) / Revenue ] × 100

Calculation Example

$500,000 Revenue ($200k COGS, $180k OpEx, $20k Tax → $100k Net Profit): Gross Margin = 60.0% | Operating Margin = 24.0% | Net Profit Margin = 20.0%.
