Gross Profit, Margin & Cost of Goods Sold (COGS

Managerial Accounting: What Belongs in COGS vs. OpEx?

Accurately calculating Gross Profit requires strictly separating product costs from operational expenses:

• COGS (Cost of Goods Sold): Direct expenses tied to manufacturing or purchasing the product (raw materials, factory labor, shipping freight, manufacturing equipment depreciation).

• OpEx (Operating Expenses): Indirect general overhead (corporate salaries, office rent, marketing ads, software subscriptions, legal fees).

The Formula

Cost of Goods Sold (COGS) & Gross Profit equations: COGS = Direct Materials + Direct Labor + Manufacturing Overhead Profit (\) = Revenue - Total COGS Margin (\%) = ((Gross Profit) / (Revenue)) × 100\% Markup (\%) = ((Gross Profit) / (Total COGS)) × 100\%-Unit Profit Contribution = (Gross Profit) / (Units Sold) = Price per Unit - COGS per Unit

Worked Example

For example, selling 3,000 units for 150,000 revenue with 42,000 materials, 24,000 labor, and 9,000 packaging overhead: Gross Profit is . The Gross Profit Margin is . Each unit yields a 25.00 gross contribution margin.

Understanding Your Result

EBITDA margin benchmarks by industry: Software/SaaS 20–40%, Healthcare services 10–20%, Retail 8–15%, Manufacturing 12–20%, Professional services 20–35%. EBITDA is not a GAAP metric and excludes capital expenditures — companies with heavy capex requirements (manufacturing, infrastructure) need to evaluate EBIT or free cash flow instead. Net profit margin below 5% indicates thin operating leverage; above 20% suggests strong pricing power or low competition in the niche.
