How to Calculate EBITDA
EBITDA is calculated by taking a company's net income and adding back four specific expenses: interest, taxes, depreciation, and amortization. The formula is straightforward: Net Income + Interest + Taxes + Depreciation + Amortization = EBITDA. You can find all these numbers on a company's financial statements — the income statement and cash flow statement — so you do not need to estimate or guess.
The reason you add these items back is that EBITDA shows what a company actually earned from its core operations, before financing decisions (interest), tax situations (taxes), and accounting write-downs (depreciation and amortization) change the picture. A company with high debt might look unprofitable on paper because of interest payments, but EBITDA strips that away to show the underlying business strength.
You can also calculate EBITDA by starting with operating income (also called EBIT) and adding back depreciation and amortization. This second route is simpler if you already have operating income in front of you: Operating Income + Depreciation + Amortization = EBITDA. Both methods produce the same result.
Key Takeaways
- EBITDA equals net income plus interest, taxes, depreciation, and amortization — all numbers you can find on the company's income statement and cash flow statement.
- You can also calculate it as operating income plus depreciation and amortization, which is faster if you have operating income already.
- Depreciation and amortization are non-cash expenses, so adding them back shows cash-generating ability rather than accounting losses.
- EBITDA is useful for comparing companies in the same industry, but it does not account for capital spending or debt repayment.
Where to Find the Numbers on Financial Statements
The income statement is your main source. It lists net income (the bottom line), operating income (also called EBIT), interest expense, and tax expense. All of these appear in order from top to bottom, so you can read them directly without calculation.
Depreciation and amortization are trickier because they sometimes appear on the income statement and sometimes on the cash flow statement. Check the income statement first — many companies list depreciation and amortization as a line item there. If you do not see them, turn to the cash flow statement, where they appear under operating activities.
For public companies in the United States, these statements are filed with the Securities and Exchange Commission (SEC) on forms called 10-K (annual report) and 10-Q (quarterly report). You can find them free on the SEC's EDGAR database or on the company's investor relations website. Private companies may not publish these statements, so EBITDA is less commonly used for them.
The Difference Between the Two Calculation Routes
The first route — Net Income + Interest + Taxes + Depreciation + Amortization — starts from the bottom of the income statement and works backward. This method is thorough and shows exactly what you are adding back, but it requires you to find four separate line items.
The second route — Operating Income + Depreciation + Amortization — starts partway down the income statement. Operating income already excludes interest and taxes, so you only need to add back depreciation and amortization. This is faster if the income statement clearly labels operating income.
Both produce identical results. Choose whichever route matches the financial statement in front of you. If the company clearly shows operating income, use the second method. If you are working from a detailed breakdown, use the first.
Why Depreciation and Amortization Matter in the Calculation
Depreciation and amortization are non-cash expenses — the company does not actually write a check for them each month. Instead, they are accounting entries that spread the cost of an asset over several years. A factory bought for $10 million might be depreciated over 20 years, so $500,000 appears as an expense each year even though the cash left the company years ago.
When you add depreciation and amortization back to net income, you are removing these non-cash charges. This shows how much cash the business actually generated from operations, separate from how accountants decided to write down assets. A company with heavy machinery might have large depreciation charges that make it look less profitable than it actually is in cash terms.
This is why EBITDA is popular in industries with lots of physical assets — manufacturing, utilities, telecommunications, and real estate. In these fields, depreciation can be so large that it masks the true operating performance.
What EBITDA Does and Does Not Tell You
EBITDA shows operating profitability — whether the core business makes money before you account for how it is financed or taxed. It is useful for comparing two companies in the same industry because it removes differences in tax rates, debt levels, and asset age that would otherwise cloud the comparison.
EBITDA does not account for capital spending (money spent on new equipment, buildings, or technology), debt repayment, or working capital changes (money tied up in inventory or accounts receivable). A company with high EBITDA might still be cash-poor if it spends heavily on new equipment or carries large debt payments. For a complete picture, you need to look at free cash flow or cash flow from operations as well.
EBITDA also does not account for one-time or unusual expenses — lawsuits, asset sales, restructuring costs — that might appear on the income statement. Some analysts adjust EBITDA to remove these items, creating what they call "adjusted EBITDA," but there is no standard definition for what counts as an adjustment.
A Worked Example
Suppose a company's income statement shows:
- Net Income: $50 million
- Interest Expense: $8 million
- Tax Expense: $12 million
- Depreciation: $15 million
- Amortization: $5 million
Using the first formula: $50 million + $8 million + $12 million + $15 million + $5 million = $90 million EBITDA.
If the same income statement shows Operating Income of $70 million, you can verify this using the second formula: $70 million + $15 million + $5 million = $90 million EBITDA. Both routes confirm the same answer.
Common Mistakes When Calculating EBITDA
The most common mistake is double-counting. If you start with operating income (which already excludes interest and taxes) and then add interest and taxes back again, you will overstate EBITDA. Stick to one formula and follow it consistently.
Another mistake is confusing depreciation with amortization or missing one of them. Depreciation applies to physical assets like buildings and equipment. Amortization applies to intangible assets like patents, trademarks, and goodwill. Both must be added back. Check both the income statement and the cash flow statement to make sure you have found them both.
A third mistake is using the wrong tax figure. Some companies list income tax expense (the tax they actually owe), while others list tax provision (an estimate). Use whichever one appears on the income statement — do not try to calculate taxes yourself.
Frequently Asked Questions
Can I calculate EBITDA if the company does not list depreciation and amortization separately?
Yes. Check the cash flow statement under operating activities — depreciation and amortization are usually listed there as adjustments to net income. If they are still not visible, you may need to read the footnotes to the financial statements, where companies sometimes bundle these items together or explain how they are treated.
Is EBITDA the same as operating income?
No. Operating income (EBIT) excludes interest and taxes but includes depreciation and amortization as expenses. EBITDA adds depreciation and amortization back, so it is always higher than operating income. Think of EBITDA as operating income plus non-cash charges.
Why would a company have negative EBITDA?
Negative EBITDA means the core business is losing money before you account for financing and taxes. This can happen in early-stage companies that are spending heavily to grow, or in mature companies facing declining sales. It is a warning sign that the business is not generating cash from operations.
Should I use EBITDA to decide whether to invest in a company?
EBITDA is one piece of information, not a complete picture. Use it alongside free cash flow, debt levels, and growth trends. A company with high EBITDA but heavy debt and negative free cash flow may be riskier than it appears. Always look at multiple metrics before making a decision.
What is adjusted EBITDA?
Adjusted EBITDA removes one-time or unusual expenses from the standard EBITDA calculation — things like lawsuit settlements, restructuring costs, or gains from asset sales. There is no standard definition, so different analysts may adjust for different items. Always ask what adjustments were made before comparing adjusted EBITDA figures.
