How to calculate EBITDA from a company's financial statements

EBITDA is earnings before interest, taxes, depreciation, and amortisation. You calculate it by starting with net income (the bottom line of the income statement) and adding back four specific costs that reduce reported profit but don't involve actual cash outflow in the current period. The formula is: Net Income + Interest + Taxes + Depreciation + Amortisation = EBITDA.

You will find all the numbers you need on two standard financial documents: the income statement (also called the profit and loss statement) and the cash flow statement. Both are public for companies listed on stock exchanges and available through the SEC's EDGAR database or the company's investor relations website. For private companies, you may need to request these statements directly.

The calculation takes five minutes once you have the documents in front of you. The harder part is understanding what each add-back represents and why it matters for the specific decision you are making — whether that is comparing two companies, understanding cash generation, or assessing how much debt a business can service.

Key Takeaways

  • EBITDA starts with net income and adds back interest expense, income tax expense, depreciation, and amortisation — all found on the income statement.
  • Depreciation and amortisation appear on the income statement but not as cash outflows, so adding them back shows operating cash generation more clearly.
  • Interest and taxes are added back because they depend on financing choices and tax jurisdiction, not on how well the business operates.
  • The same company can report different EBITDA figures depending on accounting choices for depreciation methods and asset useful life, so always check the notes to the financial statements.

Finding net income and the four add-back items on the income statement

Open the company's income statement and locate net income at the bottom — this is your starting point. Then work backwards up the statement to find the four items you will add back. Interest expense appears as a line item, usually near the bottom after operating income. Income tax expense is the line immediately above net income. Depreciation and amortisation may appear as a single line or two separate lines; if they are not visible on the income statement itself, check the cash flow statement under operating activities.

Write down each number with its sign. Interest expense and tax expense are usually shown as positive numbers (costs that reduce profit), so you will add them as positive amounts. Depreciation and amortisation are also shown as costs, so you add them back as positive amounts. The formula in practice looks like this: $50 million net income + $5 million interest + $12 million taxes + $8 million depreciation + $3 million amortisation = $78 million EBITDA.

If depreciation and amortisation do not appear on the income statement, turn to the cash flow statement. Under "Operating Activities," you will see a line for depreciation and amortisation (often grouped together). Use that figure instead. Some companies break them into separate line items; use both if they are separate.

Why you add back interest and taxes

Interest expense reflects how a company chose to finance itself — whether through debt or equity — not how well the business operates. Two identical businesses, one financed entirely with equity and one with 50% debt, will report very different net income because the debt-financed one pays interest. EBITDA removes this difference so you can compare operating performance across companies with different capital structures.

Taxes work the same way. A company's tax bill depends on its jurisdiction, tax credits, loss carryforwards, and other factors outside the control of day-to-day operations. Adding taxes back shows what the business earned before these location-specific and structure-specific costs. This matters most when comparing a company to its competitors or to itself across years when tax rates changed.

Why you add back depreciation and amortisation

Depreciation and amortisation are non-cash expenses. When a company buys a $10 million factory, it does not expense the full amount in year one. Instead, it spreads the cost over the asset's useful life — say, 20 years — and deducts $500,000 per year as depreciation. That $500,000 reduces reported profit but no cash leaves the company in that year; the cash left when the factory was purchased, years earlier.

Adding depreciation and amortisation back shows how much cash the business actually generated from operations, separate from accounting allocation decisions. A company with old, fully depreciated assets will report higher net income than an identical company with new assets still being depreciated, even though both generate the same cash. EBITDA corrects for this distortion.

Amortisation works identically but applies to intangible assets like patents, software, and goodwill (the premium paid in an acquisition). Like depreciation, it reduces reported profit without reducing cash in the current period.

Adjustments and variations in EBITDA calculations

The basic formula — net income plus interest, taxes, depreciation, and amortisation — is standard. However, some analysts and lenders add or subtract other items depending on the purpose of the calculation. Common adjustments include stock-based compensation (which reduces profit but is not a cash expense in the period it is recorded), one-time restructuring costs, or gains and losses from asset sales.

These adjusted versions are sometimes called "Adjusted EBITDA" or "Pro Forma EBITDA." They are useful for specific decisions — for example, a lender might add back restructuring costs to see what EBITDA would be once the company stabilises. However, there is no standard definition of what adjustments to make, so always ask what adjustments a company or analyst has included before comparing EBITDA figures across sources.

Depreciation methods also affect the calculation. A company using accelerated depreciation (larger deductions early on) will report lower net income in early years than one using straight-line depreciation (equal deductions each year), even if both own identical assets. Check the notes to the financial statements to see which method the company uses, especially when comparing EBITDA across companies in the same industry.

Using EBITDA to compare companies or assess debt capacity

EBITDA is most useful for comparing operating performance across companies with different financing or tax situations. If you are deciding between two acquisition targets, EBITDA removes the noise of different debt levels and tax rates, letting you see which business generates more cash from its core operations.

Lenders also use EBITDA to assess how much debt a company can service. A company with $100 million in EBITDA can typically service more debt than one with $50 million EBITDA, regardless of how much depreciation each reports. Many loan agreements include covenants tied to EBITDA — for example, a requirement that the company maintain a debt-to-EBITDA ratio below 3.0.

However, EBITDA is not a substitute for net income or cash flow. A company with high EBITDA but large capital expenditure needs (new factories, equipment) may generate less actual cash than its EBITDA suggests. Always look at free cash flow — operating cash flow minus capital expenditures — for a complete picture of cash generation.

Common mistakes when calculating EBITDA

The most common error is forgetting to add back all four items. Double-check that you have included interest, taxes, depreciation, and amortisation. If any are missing, your EBITDA will be too low.

A second mistake is using the wrong numbers. Interest expense on the income statement is not the same as interest paid (which appears on the cash flow statement). Use the income statement figure for EBITDA calculations. Similarly, make sure you are using the tax expense for the period, not the cash taxes paid, which may differ due to timing.

A third mistake is comparing EBITDA across companies without checking for adjusted items. One company's reported EBITDA may exclude stock-based compensation while another's includes it. Always read the footnotes or ask the company directly what adjustments, if any, have been made.

Frequently Asked Questions

Where do I find the income statement and cash flow statement?

For publicly traded companies, download the 10-K (annual report) or 10-Q (quarterly report) from the SEC's EDGAR database at sec.gov, or visit the company's investor relations website. Both documents include the income statement and cash flow statement. For private companies, you will need to request these statements directly from the company or its accountant.

What if depreciation and amortisation are combined into one line?

Use the combined figure. The calculation does not require you to separate them — you add back the total amount regardless of whether the company reports them together or separately. If you need to know the individual amounts for another purpose, check the notes to the financial statements or the cash flow statement, where they are often broken out.

Can EBITDA be negative?

Yes. If a company's net income is negative and the add-backs do not exceed that loss, EBITDA will be negative. This usually signals that the business is not generating cash from operations, even before accounting for financing and taxes. A negative EBITDA is a red flag for lenders and investors.

Is EBITDA the same as operating cash flow?

No. EBITDA is an accounting measure based on the income statement. Operating cash flow, found on the cash flow statement, shows actual cash in and out. They often differ because of changes in working capital (receivables, payables, inventory) and other timing differences. Use operating cash flow to understand actual cash movement; use EBITDA to compare operating performance.

Why do companies report EBITDA if it is not a standard accounting measure?

EBITDA removes the effects of financing, taxes, and accounting choices, making it easier to compare how well different businesses operate. Lenders rely on it to assess debt capacity. However, because there is no single standard definition, companies sometimes adjust EBITDA in ways that make their performance look better. Always calculate EBITDA yourself from the financial statements to verify what a company reports.
