EBITDA

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It measures a business’s operating profitability by removing the effects of financing decisions, tax jurisdiction, and non-cash accounting entries. For small business owners, the most practical thing to understand about EBITDA is that it is the number buyers and lenders apply a multiple to when valuing a business: a company generating $500,000 in EBITDA at a four-times multiple is worth $2 million.

The formula

EBITDA can be calculated in two ways that produce the same result. The most common starting point is net income [1]:

Alternatively, starting from revenue:

In practice, the D&A (depreciation and amortization) figure comes from the cash flow statement rather than the income statement, since most income statements embed it inside cost of goods sold or operating expenses rather than breaking it out on a separate line [2]. Both paths reach the same number when applied to the same financial data.

What each letter strips away

Each add-back in the formula removes a factor that reflects something other than the business’s core operating performance.

Interest. Interest expense depends on how a business is financed, not on how well it operates. A company that borrowed heavily to buy equipment will show more interest expense than an identical company that used owner capital. Removing interest makes it possible to compare two businesses on operational merit regardless of their financing history [1] [2].

Taxes. Corporate tax rates vary by jurisdiction, entity structure, and tax planning decisions made in prior years. Two identical businesses in different states or with different organizational histories will owe different taxes. Adding taxes back produces a pre-tax measure that is not penalized or rewarded for tax outcomes the operator may not fully control [1].

Depreciation. When a business buys a piece of long-lived equipment, accounting standards require spreading the cost over the asset’s useful life as a depreciation expense. This is a non-cash charge: no money moves when it is recorded. The cash left the building when the equipment was purchased. Adding depreciation back removes this timing artifact and focuses on cash-generative operations [2] [3].

Amortization. Amortization does for intangible assets what depreciation does for tangible ones. A company that purchased a trademark or customer list records amortization to allocate that cost over time. Like depreciation, it is non-cash. Both add-backs were described formally in the Berkshire Hathaway 2002 letter, where Warren Buffett also noted that the add-backs can obscure real costs when the assets in question must eventually be replaced [5].

EBITDA in valuation: the multiple

The reason EBITDA matters to business owners is not accounting theory. It is valuation. Buyers of private companies generally pay a price expressed as a multiple of EBITDA, called the EV/EBITDA multiple (enterprise value divided by EBITDA). A business with $400,000 of EBITDA selling at a five-times multiple trades for $2 million. The same business at a three-times multiple trades for $1.2 million. The multiple is the terrain that determines the exit price [4] [6].

Multiples vary by industry, size, and growth rate. Aswath Damodaran of NYU Stern School of Business publishes annual EV/EBITDA multiples by sector that are widely used as benchmarks [4]. For small and lower-middle-market businesses, the International Business Brokers Association’s Market Pulse survey tracks actual transaction multiples by sector and deal size [7]. As of recent surveys, main street businesses (under $2 million in revenue) typically sell at three to five times EBITDA, while lower-middle-market deals (enterprise value between $5 million and $50 million) commonly range from five to eight times EBITDA, with the spread driven largely by industry fragmentation, recurring revenue, and customer concentration [7].

The difference between a three-times and a five-times multiple on $500,000 of EBITDA is a $1 million difference in proceeds. That spread is why business owners preparing to sell spend as much time analyzing the multiple they can expect as they do improving the EBITDA itself [6].

Adjusted EBITDA and addbacks

Reported EBITDA is rarely the number buyers use to set a price. In the sale of a closely held business, the seller and buyer negotiate an adjusted EBITDA that adds back expenses that are personal, one-time, or above market. This adjusted figure is also called normalized or recasted EBITDA [8] [9].

Common addbacks include owner compensation in excess of a market-rate salary for a replacement manager, personal expenses that run through the business such as automobile payments, family travel, and health insurance for non-employee family members, one-time legal or consulting fees not expected to recur, and accelerated depreciation on assets that are fully functional and will not require near-term replacement [8].

A simple example: an owner of a distribution business who pays a personal car lease through the company and takes a salary of $450,000 while a market-rate general manager would cost $180,000 can add back $270,000 in excess compensation plus the car lease. If EBITDA as reported is $600,000, adjusted EBITDA could reach $900,000. At four times, that addback discussion alone shifts the valuation by $1.2 million. Addback discipline is the central work of quality of earnings analysis, and the Harvard Law School Forum on Corporate Governance has documented how inconsistent addback practices produce material discrepancies in transaction pricing [8].

Sellers should maintain clean documentation for every addback. Buyers and their advisors will scrutinize each one. Undocumented addbacks that cannot be traced to tax returns or bank statements are typically rejected during due diligence.

What EBITDA does not show

EBITDA removes depreciation to neutralize accounting timing differences. The practical consequence is that it also removes the signal that assets are wearing out and will eventually need to be replaced. A manufacturing business with $1 million in EBITDA and $600,000 in annual capital expenditures to replace aging machinery has a very different cash profile than a services business with the same EBITDA and no required reinvestment [2] [3].

For this reason, analysts and acquirers in capital-intensive industries often prefer EBITDA minus capex (sometimes called maintenance capex) as a closer proxy for distributable cash. The gap between EBITDA and free cash flow is larger in manufacturing, transportation, and logistics than in software or consulting, which is one reason EV/EBITDA multiples differ so much by sector [4].

Working capital also disappears from the EBITDA calculation. A growing business that funds 60-day receivables while paying suppliers in 30 days consumes cash as revenue grows, even as EBITDA rises. The cash flow statement, not the EBITDA figure, captures this friction.

Finally, EBITDA ignores debt service. A business with $800,000 in EBITDA and a $750,000 annual loan payment has very little free cash for the owner, regardless of how the top-line metric reads. Lenders frequently use debt service coverage ratios built from EBITDA as covenant benchmarks, but the ratio must be read alongside the absolute size of the obligation, not the EBITDA in isolation [6] [9].

How to use EBITDA as a business owner

EBITDA works well as a comparative measure over time within the same business. Tracking it monthly alongside revenue shows whether the margin between revenue and core operating costs is expanding or contracting, independent of financing or accounting changes. A rising EBITDA margin, calculated as EBITDA divided by revenue, signals improving operational efficiency [3] [10].

When preparing to sell or raise financing, the owner’s job is to arrive at an accurate adjusted EBITDA, document every addback with source records, and understand the typical multiple range in the relevant industry and deal size. Deloitte’s annual M&A trends reports publish context on transaction volume and valuation dynamics that help calibrate expectations at the sector level [6].

The metric becomes misleading when treated as a proxy for cash available to the owner. That figure is EBITDA minus taxes paid, minus debt service, minus maintenance capital expenditures, minus increases in working capital. In a capital-light, low-debt business with stable receivables, EBITDA and distributable cash will track each other closely. In most other businesses, the gap is the part worth understanding before any financial decision that depends on it [2] [5].
