Cost Of Revenue

Cost of revenue, also called cost of goods sold (COGS) or cost of sales, represents the direct costs incurred to produce goods or deliver services that generated revenue. This expense includes materials, direct labour, and manufacturing overhead directly tied to production. Subtracting cost of revenue from revenue yields gross profit—the first measure of profitability on the income statement.

Components vary by business type:

• Manufacturing: Raw materials, direct labour, factory overhead, shipping to warehouse
• Retail: Wholesale cost of merchandise, freight-in
• Software: Cloud hosting, third-party licenses, customer support
• Services: Direct labour costs, subcontractor fees, project materials

What cost of revenue excludes:

• Sales and marketing: Advertising, sales commissions
• General and administrative: Corporate overhead, executive salaries
• Research and development: Product development costs
• Interest expense: Financing costs

Why cost of revenue matters:

• Gross margin calculation: (Revenue - COGS) / Revenue = Gross Margin
• Unit economics: Shows profitability of each sale before overhead
• Pricing insight: Reveals the floor below which pricing destroys value
• Operational efficiency: Lower COGS relative to revenue indicates better efficiency

Analysing cost trends:

• COGS as % of revenue: Should remain stable or decline over time
• Input cost inflation: Rising raw material costs pressure margins
• Scale benefits: Larger companies often achieve lower unit costs
• Mix shifts: Changes in product mix affect overall cost ratios

Industry context:

• Software: Cost of revenue typically 15-30% of sales
• Retail: Cost of revenue typically 60-75% of sales
• Manufacturing: Cost of revenue typically 50-70% of sales
• Groceries: Cost of revenue often 75-85% of sales

Track cost of revenue trends relative to revenue growth. Rising costs as a percentage of revenue signals margin pressure that may indicate competitive dynamics, supply chain issues, or declining pricing power.
