Margin Metrics

Definition

Operating profit margin measures the percentage of revenue remaining after subtracting both the direct cost of goods sold and all operating expenses — including sales, general and administrative expenses, research and development, and depreciation. It is calculated by dividing trailing twelve-month operating income by trailing twelve-month revenue.

Operating margin shows how much profit the company's core business operations generate before interest expense and taxes. It is a better measure of operational efficiency than gross margin because it includes all the costs of running the business, not just production costs.

Formula

Operating Profit Margin = Operating Income (TTM) / Revenue (TTM)

How GeminIQ calculates this metric

GeminIQ divides TTM operating income by TTM revenue, both from SEC filings.

FAQ

Q: What is a good operating profit margin?

A: Software: 20-40%. Financials: 25-45%. Consumer staples: 10-20%. Retail: 3-8%. Airlines: 5-15%. Higher is better within a peer group, but the absolute level depends on industry structure.

Q: How does operating margin differ from net profit margin?

A: Operating margin measures profit before interest and taxes. Net profit margin measures profit after all expenses including interest, taxes, and non-operating items. The gap between the two reveals how much of the company's profit is consumed by financing costs and taxes.

Q: Why might operating margin differ between platforms?

A: Platforms may define operating income differently — some include non-recurring charges, others exclude them. Some aggregators reclassify items between operating and non-operating categories. GeminIQ uses Operating Income as reported in the filing.
