Overview of Operating Income
Definition of
Operating Income

What is Operating Income? Operating Income is a measure of a company's profitability generated from its normal, ongoing core business operations. It is calculated before the deduction of interest expense and income taxes. The formula for operating income is: Operating Income = Gross Profit - Operating Expenses (OPEX). It essentially shows the profit a company makes from its primary business activities, without considering financing costs or tax burdens. It is also often referred to as Operating Profit or Net Operating Income (NOI), and is similar to Earnings Before Interest and Taxes (EBIT).

The Importance of
Operating Income
Operating Income is important because it isolates the profitability of a company's core business activities, excluding the effects of its capital structure (interest expense) and tax obligations. This makes it a valuable indicator of how well management is running the fundamental operations of the business. Investors and analysts often look at operating income to assess the earning power of a company's main activities and to compare operational efficiency between companies in the same industry. For business owners, tracking operating income helps in understanding the health of their primary revenue streams and the effectiveness of their operational cost management before considering financing and tax strategies.
