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.
