Profit Margin Types Overview

A profit margin is defined as a ratio that divides a profitability metric by revenue.

By comparing the profit metric to revenue, one can evaluate the profitability of a company after deducting certain types of expenses – which helps triangulate where a company’s expenses are concentrated (i.e. cost of goods sold, operating expenses, non-operating expenses).

Profit Margin Formula

For practically all profit margins, the general “plug-in” formula follows the following format:

Profit Margin = (Profit Metric / Revenue)

Typically, profit margins are denoted in percentage form, so the figure is then multiplied by 100.

Profit Margin Types Summary Chart

The chart below lists the most common profit margins used for assessing companies.

Profit Margin Definition Formula
Gross Margin
  • The percentage of revenue remaining once COGS have been subtracted.
  • COGS are the direct costs associated with the revenue generation of a company (e.g. direct materials, direct labor).
Gross Margin = Gross Profit / Revenue
Operating Margin
  • The percentage of profitability remaining once operating expenses have been deducted from gross profit.
Operating Margin = EBIT / Revenue
Net Profit Margin
  • The percentage of accrual profitability remaining after all expenses have been subtracted.
Net Profit Margin = Net Income / Revenue
  • The percentage of revenue remaining after all operating direct and indirect costs have been deducted – but D&A is added back due to being a non-cash expense.
EBITDA Margin = EBITDA / Revenue

Profit Margin Comparisons

Core Operating Line Items

The operating margin (or EBIT) represents the line on the income statement that splits core, ongoing business operations from non-operational line items.

Financing activities like interest on debt obligations are categorized as a non-operating expense because decisions on how to finance a company are discretionary to management (i.e. the decision to fund using debt or equity).

For comparative purposes, EBIT and EBITDA are used most frequently due to how the company’s operational performance is portrayed – while remaining independent of capital structure and taxes.

Profit margins that are independent of discretionary decisions such as the capital structure and taxes (i.e. jurisdiction-dependent) are most useful for peer comparisons.

When it comes to company-to-company comparisons, isolating the core operations of each company is important – otherwise, the values would be skewed by non-core, discretionary items.

Non-Core Line Items

By contrast, profitability metrics that are below operating income line (i.e. post-levered) have adjusted EBIT for non-operating income/(expenses), which are classified as discretionary and non-core to the company’s operations.

An example is the net profit margin, since non-operating income/(expenses), interest expense, and taxes are all factored into the metric.

Unlike the operating margin and EBITDA margin, the net profit margin is directly impacted by how the company is financed and the applicable tax rate.


For purposes of comparison among different comparable companies, the two most commonly used profit margins are:

  1. Operating Margin
  2. EBITDA Margin

The notable difference between the two is that EBITDA is a non-GAAP measure that adds back non-cash expenses (e.g. D&A).

In particular, depreciation and amortization represent non-cash accounting conventions used to match CapEx spend with the corresponding revenue generated under the matching principle.

Besides D&A, EBITDA can also be adjusted for stock-based compensation as well as other non-recurring charges. The adjustments are done to remove the effects of non-cash expenses and non-recurring, one-time items.

Profit Margin by Industry

Determining whether a company’s profit margin is “good” or “bad” depends on the industry in question.

Hence, comparisons among companies operating in different industries are not recommended and are likely to lead to misleading conclusions.

To provide some brief examples, software companies are well-known for exhibiting high gross margins, yet sales & marketing expenses often cut into their profitability significantly.

On the other hand, retail and wholesale stores have low gross margins due to most of their expenses being related to:

  • Direct Labor
  • Direct Material (i.e. Inventory)

Salesforce – Software CRM Example

As a real-life example, we’ll look at the margin profile of Salesforce (NYSE: CRM), a cloud-based platform oriented around customer relationship management (CRM) and related applications.

In the fiscal year 2021, Salesforce had the following financials:

  • Revenue: $21.3bn
  • COGS: $5.4bn
  • OpEx: $15.4bn

Given those data points, Salesforce’s gross profit is $15.8bn whereas its operating income (EBIT) is $455m.

Of the core operating costs – i.e. COGS + OpEx – the corresponding % of revenue amounts were:

  • COGS % Revenue: 25.6%
  • OpEx % Revenue: 72.3%

Furthermore, the gross and operating margins of Salesforce in 2021 were:

As mentioned earlier, Salesforce is an example of a software company with high gross margins but with substantial operating costs, especially for sales & marketing.

Walmart – Retail Chain Example

Next, we’ll look at Walmart (NYSE: WMT) as a retail industry example, which we’ll contrast against our prior software industry example.

For the fiscal year 2021, Walmart had the following financial data:

  • Revenue: $559.2 bn
  • COGS: $420.3 bn
  • OpEx: $116.3bn

Therefore, Walmart’s gross profit is $138.8bn while its operating income (EBIT) is $22.5bn.

Just like we did for Salesforce, the operating cost breakdown (i.e. % of revenue) is as follows:

  • COGS % Revenue: 75.2%
  • OpEx % Revenue: 27.7%

Furthermore, the margins of Walmart were:

  • Gross Margin: 24.8%
  • Operating Margin: 4.0%

From our retail example, we can see how inventory and direct labor comprised the majority of Walmart’s total core expenses.
