EBITDA is earnings before interest, taxes, depreciation, and amortization. It starts from operating profit and adds back four costs that reflect how a business is financed and how its assets are accounted for, rather than how the underlying operation performs. Buyers use it because it makes different businesses comparable.
What does EBITDA actually measure?
It approximates the cash earnings an operation produces before the current owner's financing and tax decisions are layered on top.
Each of the four add-backs exists for that reason. Interest reflects how much the owner chose to borrow, and a buyer will bring their own capital structure. Taxes reflect the entity type and the owner's circumstances, which will change hands. Depreciation and amortization are non-cash accounting entries that spread historic spending across later years; they matter, but they are not money leaving the business this year.
Strip those out and you have a figure that lets a buyer compare two businesses on operating performance alone.
Why do buyers rely on it?
Because it is the closest widely-accepted shorthand for transferable earnings, and because valuation multiples are quoted against it.
For most established private companies, a buyer normalizes EBITDA and then applies a multiple typical for the industry. That makes EBITDA the number the multiple is applied to, which is why the earnings figure often matters more than the multiple itself. The mechanics are covered in how buyers value a privately held business.
Where does EBITDA mislead?
In three places worth knowing before you quote your own.
It is not cash flow. EBITDA ignores capital expenditure and working capital, both of which consume real money. A manufacturer that reinvests heavily in equipment, or one whose growth ties up cash in inventory and receivables, can show strong EBITDA and generate very little free cash.
It is not a GAAP measure. There is no single official definition, so calculations vary. The SEC's guidance on non-GAAP financial measures exists partly because adjusted versions of EBITDA can be presented in misleading ways, and it treats excluding normal recurring operating costs as a warning sign. Private transactions are not governed by that rule, but sophisticated buyers apply a similar test.
Reported EBITDA is rarely the number used. Buyers rebuild it, adding back above-market owner compensation and genuinely one-time costs, and subtracting where the owner has been underpaying themselves. That rebuilt figure is what gets multiplied. See which add-backs buyers accept and reject.
Does EBITDA apply to your business?
Not always. Smaller owner-operated businesses are usually assessed on SDE, which treats one working owner's compensation as a benefit of ownership rather than a cost of operating. The dividing line is largely about scale and how much the business depends on you: see EBITDA vs SDE.
If EBITDA is the right frame for your business, our valuation calculator applies a multiple to a normalized version of it and returns a range and midpoint. Treat that as a directional starting point rather than a formal appraisal.
