Source-derived summary

In business, operating margin—also known as operating income margin, operating profit margin, EBIT margin and return on sales (ROS) - is the ratio of operating income ("operating profit" in the UK) to net sales, usually expressed in percent.

Operating margin

=

Operating income

Revenue

.

{\displaystyle {\text{Operating margin}}={\frac {\text{Operating income}}{\text{Revenue}}}.}

Net profit measures the profitability of ventures after accounting for all costs.

Return on sales (ROS) is net profit as a percentage of sales revenue. ROS is an indicator of profitability and is often used to compare the profitability of companies and industries of differing sizes. Significantly, ROS does not account for the capital (investment) used to generate the profit. In a survey of nearly 200 senior marketing managers, 69 percent responded that they found the "return on sales" metric very useful.

Unlike Earnings before interest, taxes, depreciation, and amortization (EBITDA) margin, operating margin takes into account depreciation and amortization expenses. {NNP = GNP- depreciation /GNP = GDP- depreciation}

Purpose

These financial metrics measure levels and rates of profitability. Probably the most common way to determine the successfulness of a company is to look at the net profits of the business.

Editorial summary

This brief starts where responsible research should: with the source description of “Operating margin” as relating operating profits to net sales. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 191-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Operating, margin and relating can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as relating operating profits to net sales. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q722249. None of the 0 selected statements returned an explicit reference.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
