What Is EBITDA? A Plain-English Guide for Business Owners

EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It measures a company's operating profitability while ignoring how the business is financed, taxed, or how its assets are depreciated. Buyers and lenders use EBITDA to compare businesses on a like-for-like basis.

EBITDA is the most used and most misused word in the language of buying and selling businesses. Here is what it actually is, why anyone cares, and where it misleads.

The definition, unpacked

Start with net income, the bottom line of your profit and loss statement. Then add back four items:

• Interest, because how a business is financed is the owner's choice, not a feature of the operations.
• Taxes, because tax outcomes depend on entity structure and jurisdiction, which change with new ownership.
• Depreciation and amortization, because these are accounting allocations of past purchases, not cash leaving the building this year.

What remains is a rough proxy for the operating cash the business generates, independent of financing and accounting decisions. That neutrality is why a buyer comparing a plumbing company in Charlotte with a machine shop in Ohio reaches for EBITDA: it puts different businesses on the same footing.

Adjusted EBITDA: where the real conversation happens

In private company deals, the number that matters is usually adjusted EBITDA. Adjustments normalize the earnings for things that will not continue under new ownership: above-market or below-market owner salary, one-time expenses like a lawsuit or a flood repair, personal expenses run through the business, and rent paid to a related party at non-market rates.

Every adjustment will be scrutinized by a buyer's diligence team, so the standard is simple: an adjustment is credible if a reasonable stranger would agree it will not recur. Aggressive add-backs are one of the fastest ways to lose a buyer's trust.

Where EBITDA misleads

EBITDA ignores capital expenditure. A trucking company must continuously replace trucks; a consulting firm buys laptops. Both can show the same EBITDA while generating very different real cash flow. Buyers know this, which is why capital-intensive businesses often trade at lower multiples of EBITDA than asset-light ones. EBITDA is a comparison tool, not a substitute for understanding cash.

EBITDA or SDE?

For smaller, owner-operated businesses, the more common earnings measure is seller's discretionary earnings, which treats the owner's full compensation differently. Using the wrong measure with the wrong multiple produces nonsense numbers. We break down the difference in our SDE vs EBITDA guide.
