Most business owners do not know their EBITDA. They have heard the term. They know it has something to do with valuation. But if asked to calculate it on the spot, they could not. That gap matters more than most owners realize, because EBITDA is what determines what their business is worth.
EBITDA is also what determines whether a lender will extend credit, what terms a partner will accept, and what a buyer will offer. It is the single most-asked-about number in any serious conversation about the financial health of a business. Owners who can speak to their EBITDA confidently are positioned differently in every one of those conversations than owners who cannot.
This article walks through what EBITDA is, why it matters, and what most owners get wrong about it.
What EBITDA Stands For
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. Each layer of cost gets removed for a specific reason.
Interest is removed because it reflects how the business is financed, not how well it operates. Two identical businesses can have very different interest expense based on whether they borrowed to buy equipment or paid cash. Removing interest from the comparison strips out the financing decision.
Taxes are removed because they reflect how the business is structured (S-corp, C-corp, LLC) and how the owner has chosen to optimize. Tax structure varies significantly between businesses and is a separate decision from operational performance.
Depreciation and Amortization are removed because they are non-cash items. Depreciation reflects the gradual recognition of long-term asset costs (equipment, real estate, vehicles) for accounting purposes. The cash for those assets was spent in a prior period. Removing depreciation from EBITDA gives a cleaner picture of the cash-generating potential of the operating business.
What is left after those four are removed is the operating earnings of the business itself, independent of how it has been financed, taxed, or accounted for.
Why Buyers and Lenders Use It
EBITDA is the standard metric in mergers, acquisitions, and lending because it allows businesses to be compared on equal footing.
A business with $500,000 in EBITDA can be compared directly against another business with $500,000 in EBITDA, regardless of how each is financed or how each owner has structured their taxes. That comparison is impossible if the conversation is about net income, where one business might be carrying $200,000 in interest expense and the other might be debt-free.
Buyers also use EBITDA because it is the input into the multiple-of-earnings valuation method. When a buyer says they will pay 4x EBITDA for a business, they mean the purchase price will be four times the Adjusted EBITDA. That single relationship determines what a business is worth.
EBITDA is what determines what their business is worth.
How to Calculate It
The simplest way to calculate EBITDA starts from operating income and adds back depreciation and amortization:
EBITDA = Operating Income + Depreciation + Amortization
Operating income is already on the P&L (also called operating profit or income from operations). Depreciation and amortization come from the P&L or the cash flow statement, depending on how they are reported.
As an example, a business with $2,100,000 in revenue, $798,000 in COGS, $864,000 in operating expenses, and $45,000 in depreciation generates $483,000 in EBITDA. The math: $2,100,000 minus $798,000 equals $1,302,000 in gross profit. Minus $864,000 in operating expenses equals $438,000 in operating income. Plus $45,000 in depreciation equals $483,000 in EBITDA.
That number is the starting point. It is not the final number.
Adjusted EBITDA: The Number That Actually Drives Value
Raw EBITDA is what shows up in the financial statements as reported. Adjusted EBITDA is the number a buyer or sophisticated lender will actually use.
Adjustments fall into three categories.
Owner compensation normalization. If an owner pays themselves above what a market-rate replacement would cost for the same role, the difference is added back. The buyer is not going to pay the seller; they are going to hire someone at market rate. The true earnings of the business are therefore higher than the raw number suggests.
One-time and non-recurring items. Unusual legal expenses, equipment repairs that will not repeat, costs associated with a specific project that has ended, or any other expenses that are not part of the normal ongoing operation of the business get added back. Conversely, one-time revenue events get removed.
Personal expenses run through the business. Vehicles, phones, club memberships, and other personal costs that have been classified as business expenses get added back. They are not true operating expenses and they should not reduce the apparent earnings of the business.
The gap between raw EBITDA and Adjusted EBITDA is often substantial. For a business with raw EBITDA of $483,000, an owner paid $80,000 above market, $50,000 in one-time legal fees, and $12,000 in personal vehicle expenses, Adjusted EBITDA might be $590,000 (after also removing a $35,000 one-time equipment sale revenue). At a 4x multiple, that $107,000 difference is worth $428,000 in enterprise value.
What Most Owners Miss
The single most common mistake is treating raw EBITDA as the number that drives valuation. It does not. Adjusted EBITDA does. Owners who present raw EBITDA in a sale conversation undersell their business. Owners who claim Adjusted EBITDA without documentation cannot defend the number under diligence. Both extremes leave value on the table.
The second mistake is confusing EBITDA with cash. EBITDA is not cash flow. A business can have strong EBITDA and still run out of cash if collections are slow, inventory is rising, or capital expenditures are consuming the operating earnings. EBITDA tells you about earnings power. It does not tell you about timing.
The third mistake is waiting until a sale process to think about EBITDA. EBITDA is a health number that matters every year, not just at exit. Owners who track Adjusted EBITDA quarterly understand their business better. They know what is driving value up and what is dragging it down. They can make deliberate decisions about owner compensation, one-time costs, and personal expenses years before any sale is on the horizon.
What to Do With It
Knowing the EBITDA of a business is useful at every stage of ownership. For an owner who is years away from selling, it is a scorecard for whether the business is being built well. For an owner who is approaching a sale, it is the floor for negotiation.
The Owner’s Financial Playbook calculates raw and Adjusted EBITDA from the reader’s own QuickBooks data, then teaches how to read what those numbers are saying about the business. By Module 9 the reader has a complete valuation range built from their own EBITDA, with a clear list of what is driving the multiple up or down.
