EV/EBITDA: What It Is, How to Calculate It and When to Use It

EV/EBITDA is one of the most widely used valuation multiples in finance — a quick, powerful way to gauge what a business is worth relative to its earnings. Analysts, investors and dealmakers reach for it constantly, especially when comparing companies. This guide explains what EV/EBITDA is, how it's calculated, why it's so popular, and its limitations. It's essential knowledge for anyone studying valuation or working in corporate finance.

What is the EV/EBITDA multiple?

EV/EBITDA compares a company's enterprise value (EV) to its earnings before interest, tax, depreciation and amortisation (EBITDA). In essence, it tells you how many times a company's annual operating earnings the market is valuing the whole business at. A lower multiple can suggest a company is relatively cheap; a higher one suggests it's more expensive (or expected to grow faster). Because it's a ratio, it lets you compare businesses of very different sizes on a like-for-like basis.

The two components

• Enterprise value (EV) is the value of the whole business — to all providers of capital, both equity and debt. It's typically calculated as market capitalisation plus total debt, minus cash and cash equivalents. The idea is that EV represents what it would effectively cost to acquire the entire business: you'd pay for the equity, take on the debt, but benefit from the cash on the balance sheet.
• EBITDA is a measure of operating profitability that strips out interest, tax, depreciation and amortisation. By removing these, EBITDA aims to show the underlying cash-generating performance of the core operations, independent of how the company is financed, its tax position, or its accounting for non-cash charges.

A simple example

Suppose a company has a market capitalisation of £400m, debt of £150m and cash of £50m. Its enterprise value is £400m + £150m − £50m = £500m. If its EBITDA is £100m, its EV/EBITDA multiple is £500m / £100m = 5×. To value a similar private company with EBITDA of £20m, you might apply a comparable sector multiple — say 6× — to estimate an enterprise value of around £120m. There's no universal "good" multiple, though: what's normal varies widely by industry, growth prospects and market conditions, which is exactly why the comparison must be like-for-like.

Why EV/EBITDA is so popular

EV/EBITDA has some real advantages over simpler multiples like the price-to-earnings (P/E) ratio. Because EV captures both debt and equity, and EBITDA is measured before interest, the multiple is capital-structure neutral — it lets you compare companies with very different levels of debt on a fair basis, which P/E doesn't. Stripping out depreciation and amortisation also reduces the distortion from different accounting policies and investment levels. And because EBITDA is before tax, it eases comparison across different tax regimes. For comparing companies in the same sector, these features make it a favourite.

How it's used

EV/EBITDA is used mainly for relative valuation: you calculate the multiple for a set of comparable companies, establish a typical or benchmark multiple for the sector, and apply it to the EBITDA of the company you're valuing to estimate its enterprise value. It's central to comparable company analysis and is widely used in mergers and acquisitions to gauge whether a deal price is reasonable relative to the market.

The limitations

EV/EBITDA is useful but not flawless, and its main criticism centres on EBITDA itself. By ignoring depreciation and amortisation, EBITDA overlooks the real cost of the capital investment a business needs to keep running — which matters a lot for asset-heavy companies. It also ignores changes in working capital and isn't a measure of free cash flow, so a healthy EBITDA doesn't always mean healthy cash generation. And like all multiples, it's only as good as the comparables used: the companies must be genuinely similar for the comparison to be meaningful. It's best used alongside other methods, such as discounted cash flow, rather than on its own.

Frequently asked questions

What does EV/EBITDA tell you?

How many times its annual operating earnings (EBITDA) the market values the whole business (enterprise value) at — a way to gauge whether a company is relatively cheap or expensive.

How is enterprise value calculated?

Typically as market capitalisation plus total debt, minus cash and cash equivalents — the effective cost of acquiring the whole business.

Why is EV/EBITDA preferred over P/E?

Because it's capital-structure neutral (EV includes debt and EBITDA is before interest), allowing fair comparison of companies with different debt levels, and it reduces accounting and tax distortions.

What are the limitations of EV/EBITDA?

EBITDA ignores the real cost of capital investment (depreciation), working capital and cash flow, so it can flatter asset-heavy businesses. It also depends on genuinely comparable companies.
