# Operating Margin: What It Is and Formula

> **Definition**

> Operating margin is a company's profit for every dollar of sales after deducting production costs like wages and raw materials but before accounting for interest and taxes.

## What Is Operating Margin?

A company's operating margin is the amount it makes on every dollar of sales after deducting the [variable costs](https://www.investopedia.com/terms/v/variablecost.asp) involved but before accounting for interest or taxes. Operating margin is calculated by dividing the company’s operating income by its [net sales](https://www.investopedia.com/terms/n/netsales.asp).

A higher ratio in an operating margin is generally better, as it indicates the company is efficient in its operations and is good at turning sales into profits. 

### Key Takeaways

*   A company's operating margin indicates how effective it is at generating a profit through its core operations.
*   The formula for operating margin yields the percentage profit made on each dollar of sales.
*   Operating margin is reduced by the company's variable costs of production but does not consider the costs of interest or taxes (EBIT).
*   To calculate operating margin, divide operating income (earnings) by sales (revenues).

## Understanding Operating Margin

A company’s operating margin, sometimes referred to as [return on sales](https://www.investopedia.com/terms/r/ros.asp) (ROS), is a good indicator of how well it is being managed and how efficient it is at generating profits from sales. It shows the proportion of revenues that are available to cover non-operating costs, such as paying [interest](https://www.investopedia.com/terms/i/interest.asp), which is why investors and lenders pay close attention to it.

Highly variable operating margins are a prime indicator of business risk. By the same token, looking at a company’s past operating margins is a good way to gauge whether a company's performance has been getting better. The operating margin can improve through better management controls, more efficient use of resources, improved pricing, and more effective marketing.

In its essence, the operating margin is how much profit a company makes from its core business in relation to its total revenues. This allows investors to see if a company is generating income primarily from its core operations or from other means, such as investing.

## Calculating Operating Margin

The formula for operating margin is:

﻿ $\begin{aligned} \text{Operating Margin}=\frac{\text{Operating Earnings}}{\text{Revenue}} \end{aligned}$﻿﻿

When calculating operating margin, the numerator uses a firm's [earnings before interest and taxes](https://www.investopedia.com/terms/e/ebit.asp) (EBIT). EBIT, or [operating earnings](https://www.investopedia.com/terms/o/operatingearnings.asp), is calculated simply as revenue minus [cost of goods sold](https://www.investopedia.com/terms/c/cogs.asp) (COGS) and the regular selling, general, and administrative costs of running a business, excluding interest and taxes.

### Example

For example, if a company had revenues of $2 million, COGS of $700,000, and [administrative expenses](https://www.investopedia.com/terms/a/administrative-expenses.asp) of $500,000, its operating earnings would be $2 million - ($700,000 + $500,000) = $800,000. Its operating margin would then be $800,000 / $2 million = 40%.

If the company was able to negotiate better prices with its suppliers, reducing its COGS to $500,000, then it would see an improvement in its operating margin to 50%.

## Limitations of the Operating Margin

The operating margin should only be used to compare companies that operate in the same industry and, ideally, have similar [business models](https://www.investopedia.com/terms/b/businessmodel.asp) and annual sales. Companies in different industries with wildly different business models have very different operating margins, so comparing them would be meaningless. It would not be an apples-to-apples comparison.

To make it easier to compare profitability [between companies and industries](https://www.investopedia.com/ask/answers/052015/which-industries-tend-have-greatest-ebitda-margins.asp), many analysts use a profitability ratio that eliminates the effects of financing, accounting, and tax policies: [earnings before interest, taxes, depreciation, and amortization](https://www.investopedia.com/terms/e/ebitda.asp) (EBITDA). For example, by adding back depreciation, the operating margins of big manufacturing firms and heavy industrial companies are more comparable.

EBITDA is sometimes used as a proxy for [operating cash flow](https://www.investopedia.com/terms/o/operatingcashflow.asp) because it excludes non-cash expenses, such as depreciation. However, EBITDA does not equal cash flow. This is because it does not adjust for any increase in [working capital](https://www.investopedia.com/terms/w/workingcapital.asp) or account for capital expenditure that is needed to support production and maintain a company’s asset base—as operating cash flow does.

## Other Profit Margins

By comparing EBIT to sales, [operating profit margins](https://www.investopedia.com/ask/answers/010815/what-difference-between-gross-profit-margin-and-operating-profit-margin.asp) show how successful a company's management has been at generating income from the operation of the business.  There are several other margin calculations that businesses and analysts can employ to get slightly different insights into a firm's profitability.

The [gross margin](https://www.investopedia.com/terms/g/grossmargin.asp) tells us how much profit a company makes on its cost of sales or COGS. In other words, it indicates how efficiently management uses labor and supplies in the production process.

The [net margin](https://www.investopedia.com/terms/n/net_margin.asp) considers the net profits generated from all segments of a business, accounting for all costs and accounting items incurred, including taxes and depreciation. In other words, this ratio compares [net income](https://www.investopedia.com/terms/n/netincome.asp) with sales. It comes as close as possible to summing up in a single figure how effectively the managers are running a business.

## Why Is Operating Margin Important?

The operating margin is an important measure of a company's overall profitability from operations. It is the ratio of operating profits to revenues for a company or business segment.

Expressed as a percentage, the operating margin shows how much earnings from operations is generated from every $1 in sales after accounting for the direct costs involved in earning those revenues. Larger margins mean that more of every dollar in sales is kept as profit.

## How Can Companies Improve Their Operating Profit Margin?

When a company's operating margin exceeds the average for its industry, it is said to have a [competitive advantage](https://www.investopedia.com/terms/c/competitive_advantage.asp), meaning it is more successful than other companies that have similar operations. While the average margin for different industries varies widely, businesses can gain a competitive advantage in general by [increasing sales or reducing expenses](https://www.investopedia.com/ask/answers/122214/company-it-more-important-lower-costs-or-increase-revenue.asp)—or both.

Boosting sales, however, often involves spending more money to do so, which equals greater costs. Cutting too many costs can also lead to undesirable outcomes, including losing skilled workers, shifting to inferior materials, or other losses in quality. Cutting advertising budgets may also harm sales.

To reduce the cost of production without sacrificing quality, the best option for many businesses is expansion. [Economies of scale](https://www.investopedia.com/insights/what-are-economies-of-scale/) refer to the idea that larger companies tend to be more profitable. A large business's increased level of production means that the cost of each item is reduced in several ways. For example, raw materials purchased in bulk are often discounted by wholesalers.

## How Is Operating Margin Different From Other Profit Margin Measures?

Operating margin takes into account all operating costs but excludes any non-operating costs. Net profit margin takes into account all costs involved in a sale, making it the most comprehensive and conservative measure of profitability. Gross margin, on the other hand, simply looks at the costs of goods sold (COGS) and ignores things such as [overhead](https://www.investopedia.com/terms/o/overhead.asp), fixed costs, interest expenses, and taxes.

## What Are Some High and Low Profit Margin Industries?

High-profit margin sectors are typically those where competitive pressures allow companies to generate sales that are produced without having to spend much on development, marketing, overheads, and production. Initially, start-up companies may make losses until they establish themselves. For example, software or gaming companies may invest initially while developing a particular software/game and cash in big later by simply selling millions of copies with very few expenses.

Operations-intensive businesses such as transportation, which may have to deal with fluctuating fuel prices, drivers’ perks and retention, and vehicle maintenance, usually have lower profit margins. Automobiles also have low profit margins, as profits and sales are limited by intense competition, uncertain consumer demand, and high operational expenses involved in developing dealership networks and logistics.
