Understanding Differences Between Operating Income and EBITDA

Understanding your company’s financial health means knowing the right numbers to focus on. Two common metrics you’ll hear about to assess business performance are operating income and EBITDA. While they might seem similar, each tells a different story about your business’s profitability and cash flow.

EBITDA is typically higher than operating income because it adds back depreciation and amortization, which can be a significant portion of operating expenses, sometimes exceeding 90% of operating income. Understanding the difference between operating income vs. EBITDA helps you make smarter decisions and manage daily operations. In this blog, we’ll explain what operating income and EBITDA mean, how they’re calculated, and when to use each.

What Is Operating Income?

Operating income, also known as operating profit or EBIT (Earnings Before Interest and Taxes), measures the profit a company earns from its core business activities. It reflects the amount of money remaining after covering the costs necessary to run the business, but before paying interest or taxes.

How to Calculate Operating Income

There are two common ways to calculate operating income:

• Bottom-Up Approach:
  Start with gross profit (revenue minus cost of goods sold). Then, subtract operating expenses, such as selling, general, and administrative costs, as well as depreciation and amortization. This method isolates the profit generated solely from core business operations.

Bottom-Up Formula: Operating Income = Gross Profit − Operating Expenses − Depreciation − Amortization

Depreciation accounts for the wear and tear on physical assets, such as equipment, while amortization spreads out the cost of intangible assets, like patents or trademarks, over their useful life. '

Amortization is the gradual expense of spreading the cost of an intangible asset, like patents or trademarks, over its useful life to reflect its declining value over time.

This method begins with gross profit (revenue minus the cost of goods sold) and then subtracts operating costs and non-cash expenses, such as depreciation.

• Top-Down Approach:
  Begin with net income, then add back interest and tax expenses. This removes the effects of financing costs and taxes, highlighting the earnings from operating activities.

Top-Down Formula: Operating Income = Net Income + Interest Expenses + Tax Expenses

Both approaches yield the same operating income figure but offer different perspectives depending on the available data. 

Now that we’ve covered operating income, let’s take a look at EBITDA and what it means.

What Is EBITDA?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It’s a financial metric that helps you understand a company’s operating performance by focusing on earnings from its core business activities. By excluding interest, taxes, and non-cash expenses such as depreciation and amortization, EBITDA provides a clear view of the company’s ability to generate cash from operations.

This measure is useful when comparing companies, as it removes factors that can vary widely due to financing decisions or accounting policies.

How to Calculate EBITDA

If you want to calculate EBITDA yourself or interpret reported figures, here’s the basic formula:

EBITDA = Operating Income + Depreciation + Amortization

Some companies also report an “adjusted EBITDA,” which removes one-time or unusual expenses to give a clearer view of ongoing performance.

While EBITDA gives valuable insight, it’s important to remember that it doesn’t account for all expenses, such as interest payments or investments in equipment. Therefore, it’s best used with other financial metrics to gain a comprehensive understanding of a company’s financial health.

To make these ideas straightforward, let’s walk through some examples of how to calculate both operating income and EBITDA.
