Frequently Asked Questions
Why is operating margin considered superior to net margin for comparing companies?↓
Operating margin excludes debt interest structures and corporate tax jurisdiction differences, allowing investors to evaluate pure operational efficiency without capital structure distortion.
What is an average operating margin across US industries?↓
The average operating margin across S&P 500 companies historically ranges between 11% and 13%. Asset-light software companies often achieve 25% to 35%, while retail grocery stores operate on 2% to 4%.
What causes operating margin compression?↓
Operating margin compression occurs when selling, general, and administrative (SG&A) overhead increases faster than sales revenue, or when input material inflation cannot be passed on to customers through price increases.
How does operating leverage affect operating margin expansion?↓
When a company has high fixed operating overhead, incremental sales increases flow almost entirely to operating profit, producing dramatic operating margin expansion as scale increases.
