Common Mistakes to Avoid

⚠️
Confusing operating margin with net margin

Operating margin excludes interest and taxes. Net margin is after all deductions. Operating margin isolates operational efficiency; net margin shows bottom-line result.

⚠️
Not separating COGS from operating expenses

Gross margin = revenue minus COGS. Operating margin subtracts operating expenses (sales, marketing, G&A). Mixing them gives misleading results.

⚠️
Benchmarking against wrong peers

Software: 15-30% operating margin is normal. Retail: 2-8%. Healthcare: 10-20%. Compare against your own industry, not averages across all sectors.

The core business is losing money from operations. Common in early-stage growth companies investing in sales/marketing ahead of revenue. Concerning if persistent without clear path to positive margin.
