What Is Operating Income?
Operating income is the amount of revenue left after subtracting operating expenses and cost of goods sold (COGS). Operating income is a measure of profitability directly related to a company’s operations.
Operating income is sometimes referred to as Earnings Before Interest and Taxes (EBIT). They are not synonymous terms because EBIT also includes other income or expenses that are not central to a company's business. For example, income from the firm's financial investments would be added to the operating income to determine EBIT.
How to Use Operating Income
Operating income tells investors and company owners how much revenue will eventually become profit for a company.
Operating income is important because it is an indirect measure of efficiency. The higher the operating income, the more profitable a company's core business is.
Several things can affect operating income, including:
prices for raw materials, or
These items directly relate to daily decisions that managers make. This means operating income also measures managerial competency.
The Operating Income Formula
The formula for calculating operating income is:
How to Calculate Operating Income
You will use the company income statement to calculate operating income. It is important to understand what expenses are included and what items are excluded when calculating operating income.
To calculate operating income, you must find the total revenue (gross income), COGS, and the operating expenses on the income statement. Operating expenses include:
Labor and salaries
Day-to-day expenses like rent and utilities
Operating income does not account for the following:
non-recurring items such as accounting adjustments, legal judgments, or one-time transactions, and
other income statement items not directly related to a company's core business operations
Operating Income Examples
Let’s look at two examples of operating income.
Figure 1: Company X Income Statement
Using the Income Statement for Company X and the formula found above, we can calculate the operating income:
Figure 2: Company Z Income Statement
Using the Income Statement for Company Z and the formula above, we can calculate Company Z's operating income as:
Operating Income vs Net Income
Both operating income and net income can be found on the company income statement.
Operating income subtracts COGS and operating expenses from total revenue. Net income subtracts COGS, operating expenses, interest, and taxes from total revenue.
Net income is also referred to as “the bottom line” because it’s the last entry on an income statement. Net income accounts for all expenses while operating income only accounts for expenses related to operations. To see the difference, look again at the income statement for Company X: The net income is $30,000, while the operating income is $50,000.
Operating Income vs EBITDA
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. Both operating income (which is the same as EBIT for a company without non-operating income or expenses) and EBITDA are measures of profit. Each measure of operating profitability excludes certain financial decisions, tax environments, and accounting decisions.
EBITDA shows earnings (income) before interest, taxes, depreciation, and amortization. Operating income shows income after operating expenses have been paid.
Both operating income, EBIT and EBITDA provide investment analysts with useful information for evaluating a company’s operating performance. These numbers remove variables that may be unique from company to company and enables financial experts to analyze operating profitability as a singular measure of performance. Such analysis is particularly important when comparing similar companies across a single industry because of varying capital structures or tax environments.
It is also important to note that some industries have higher labor or materials costs than others. For example, a construction company will likely have higher material costs, whereas a law firm will likely have higher labor or salary costs. That’s why comparing operating income and EBITDA is most meaningful for comparison among companies within the same industry.
