What is EBITDA — and why does it matter in company results?

What the letters actually stand for

EBITDA is an acronym: Earnings Before Interest, Taxes, Depreciation, and Amortisation. Each of those four words names a cost that is deliberately left out of the calculation.

Think of it as working backwards from net profit. You start with the bottom line and add those four items back in — revealing what the business earned purely from running its operations, before financing decisions, accounting conventions, and the taxman took their share. The result is a figure that is easier to compare across different companies and different countries than net profit on its own.

Why those four items are stripped out

Each exclusion has a specific reason. Together they remove the noise that can make two similar businesses look very different on paper.

Interest

Interest is the cost of borrowing money. Two businesses that are operationally identical can have very different interest bills if one has chosen to fund its growth with debt while the other has not. Stripping out interest means you can compare the underlying businesses without being distracted by their financing choices. You can read more about how debt affects a company in our guide to what a balance sheet is.

Taxes

Corporation tax rates vary significantly between countries. A UK company and a US company in the same industry would look very different at net profit level simply because of the different tax regimes they face. Removing tax makes international comparisons cleaner.

Depreciation

When a company buys a piece of machinery or a vehicle, it does not record the entire cost as an expense in year one. Accounting rules spread that cost across the asset’s useful life — perhaps ten or fifteen years. Each year’s share of that original cost is called depreciation. The important thing to note is that depreciation is a non-cash charge: the cash was spent when the asset was purchased, not spread evenly over the following decade. EBITDA adds depreciation back in because it does not represent cash leaving the business in the current period.

Amortisation

Amortisation works exactly the same way as depreciation, but it applies to intangible assets rather than physical ones. When a company acquires another business, it often pays for things you cannot touch: brand recognition, customer lists, patents, or software licences. These intangibles are recorded on the balance sheet and written down gradually over time. That write-down is amortisation, and it is also non-cash — so EBITDA adds it back in too.

How to calculate EBITDA

There are two routes to the same number.

If you are starting from net profit (the bottom of the income statement and the basis for earnings per share):

EBITDA = Net profit + Interest + Taxes + Depreciation + Amortisation

If you are starting from operating profit (the figure that already excludes interest and tax, but still includes depreciation and amortisation):

EBITDA = Operating profit + Depreciation + Amortisation

A worked example: imagine a FTSE 250 manufacturer reports a net profit of £18m. It paid £4m in interest on its factory debt, £3m in corporation tax, recorded £9m of depreciation on its machinery, and £2m of amortisation on a brand licence it acquired two years ago.

EBITDA = £18m + £4m + £3m + £9m + £2m = £36m

The EBITDA is exactly double the net profit. That gap tells you this is a capital-intensive business with significant debt — worth investigating further.

EBITDA versus the other profit measures

It helps to see all the profit measures together to understand where EBITDA sits:

Profit measure	What has been removed from revenue
Gross profit	Direct costs of production only (raw materials, manufacturing)
Operating profit	Gross profit minus overheads (wages, rent, marketing, R&D) and depreciation/amortisation
EBITDA	Same as operating profit, but depreciation and amortisation are added back
Net profit	Everything — including interest on debt and the full tax bill

The three profit margins (gross, operating, net) are each expressed as a percentage of revenue. EBITDA is usually presented as an absolute figure, though analysts also track the EBITDA margin — EBITDA divided by revenue — to measure how efficiently a business converts sales into operating earnings.

The EV/EBITDA ratio — EBITDA in action

The most widely used application of EBITDA in share analysis is the EV/EBITDA multiple. EV stands for Enterprise Value — roughly, what it would cost to buy the whole company, calculated as market capitalisation plus net debt.

EV/EBITDA = Enterprise Value ÷ EBITDA

This multiple tells you how many years of core operating earnings you are effectively paying to acquire the business. A ratio of 10 means you are paying ten times annual EBITDA. As with price-to-earnings ratios, lower is not automatically better — a low multiple can reflect genuine cheapness or a business with serious structural problems.

Here is a rough guide to typical ranges (though these shift with market conditions and vary significantly by sector):

• Utilities and telecoms: typically 7–12× — stable, predictable cash flows command moderate multiples
• Consumer goods and retail: often 8–15×
• Technology and software: frequently 15–30× or higher — investors pay a premium for fast growth and high margins
• Mining and commodities: highly variable, driven by commodity cycle

The right benchmark is always the company’s own sector. A 12× multiple looks expensive for a utility but cheap for a high-growth software business.

The limitations of EBITDA — what it hides

EBITDA is useful, but it is not a complete picture. Three limitations are worth keeping in mind.

It can flatter capital-intensive businesses. A steel plant or an airline needs to spend enormous sums on replacing ageing assets. Depreciation is excluded from EBITDA, but the actual cash to buy new equipment still has to come from somewhere. A business with strong EBITDA but heavy capital expenditure requirements will have far less real cash available to shareholders than the headline figure suggests. This is why analysts in capital-intensive industries often prefer to look at free cash flow instead.

It is not the same as cash flow. EBITDA adds back non-cash charges (depreciation and amortisation) but ignores changes in working capital — the cash tied up in stock, the money owed by customers, and the money owed to suppliers. A fast-growing company can have excellent EBITDA and yet be consuming cash rapidly because it is funding its growth with ever-larger inventories and longer customer payment terms.

“Adjusted EBITDA” requires scrutiny. Companies sometimes present an “adjusted” version that strips out additional items — restructuring costs, share-based compensation, one-off legal expenses. Each adjustment may be perfectly reasonable, or it may be quietly removing recurring costs to make the number look cleaner. Always check the footnotes of a results announcement to see exactly what has been excluded from the adjusted figure and whether it has appeared year after year.

Using EBITDA in the Student Investor Challenge

When one of your virtual portfolio companies releases its half-year or full-year results, EBITDA gives you a fast way to assess whether the business is becoming more or less operationally efficient — independently of how it is financed or how aggressive its accountants have been with depreciation.

Here are three quick checks to run:

1. Is EBITDA growing alongside revenue? If revenue is rising but EBITDA is flat or falling, costs are outrunning sales. Margins are being squeezed, which is usually a warning signal for future earnings and dividends.
2. Is the EBITDA margin improving? Divide EBITDA by revenue. If that percentage is trending upward, the company is converting each extra pound of sales into more operating profit — a sign of improving efficiency, often called operating leverage.
3. How does the EV/EBITDA multiple compare to peers? If a company in your portfolio trades at a noticeably higher multiple than its competitors, the market is pricing in strong future growth. That is a reasonable bet when it comes true, but a sharp de-rating risk if results disappoint.

You can find EBITDA figures in the results announcement’s financial highlights section or in the chief executive’s commentary. Most FTSE companies include it explicitly; for smaller companies, you may need to calculate it yourself using the income statement figures from the London Stock Exchange company profiles or a financial data provider such as Morningstar.

For a clear companion explanation of what depreciation and amortisation are from an accounting perspective, HMRC’s guidance on the accounting treatment of business assets is authoritative and publicly available.

Frequently asked questions

What does EBITDA stand for?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortisation. It measures how much profit a company generates from its core operations before financing costs and non-cash accounting charges are included. It sits above net profit on the income statement because those four items are excluded from the calculation.

Is EBITDA the same as profit?

No. EBITDA is a measure of operating profitability, not bottom-line profit. A company with strong EBITDA can still have weak net profit if it carries heavy debt (high interest costs), faces a large tax bill, or records significant depreciation on an ageing asset base. Always look at both figures alongside each other.

Why do analysts use EBITDA instead of net profit?

EBITDA makes it easier to compare companies across different countries and capital structures. It removes interest (which depends on how much debt a company has chosen to carry), tax (which varies by jurisdiction), and depreciation and amortisation (which depend on accounting choices and the age of a company’s assets). Stripping these out lets analysts focus on the underlying operational performance without being distracted by financing and accounting differences.

What is a good EV/EBITDA ratio?

It depends heavily on the sector. Technology and consumer brand companies often trade at 15 to 25 times EBITDA, while more stable businesses such as utilities or mature industrial companies may trade at 8 to 12 times. The right comparison is always against sector peers rather than a single universal benchmark — a multiple that looks expensive in one industry can be entirely normal in another.
