What Is EBITDA?

01 · Perspective

What Does EBITDA Stand For, and What Does It Measure?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. You calculate it by starting with a business's net income and adding each of those four items back, and what you get is a number that approximates how much cash the core operation throws off before financing decisions, tax situations, and asset-purchase accounting get involved.

Interest gets added back because how a business is financed is a decision, not a measure of how well it operates. A manufacturing business that borrowed $2 million to buy CNC equipment and one that paid cash for the same equipment can have identical operations and identical revenue, yet very different net income once interest expense is factored in. Adding interest back removes the owner's financing choices from the picture.

Taxes get added back because tax burden depends on entity structure, state of operation, and elections that have nothing to do with how the business actually performs. An S corporation and a C corporation running the same operation in the same state will show different net income purely because of how they are taxed. Removing taxes lets you compare the operations, not the tax paperwork.

Depreciation gets added back because it is a non-cash accounting expense. It spreads the cost of equipment, vehicles, or buildings over years for accounting and tax purposes, but no actual cash left the business the day depreciation was recorded. Two businesses that bought identical machines five years apart will show different depreciation schedules even though the machines cost roughly the same and generate the same output today.

Amortization works the same way for intangible assets, things like capitalized software, patents, or goodwill from a prior acquisition. It is the accounting write-down of an asset that was already paid for, not a new cash expense.

Why EBITDA Exists: Comparing Businesses on the Same Footing

EBITDA exists to let you compare businesses on operating performance alone, independent of how they are financed, how they are taxed, or how they are structured. Two businesses with identical revenue and margins can show very different net income simply because one carries debt and the other does not, or because one is taxed as an S corporation and the other as a C corporation. Look at EBITDA instead and the operational picture converges, which is why a buyer, a lender, or an advisor uses it to set financing and tax differences aside.

EBITDA is not a perfect number, and its real limitations come later in this article, but it remains the most widely used starting point for comparing businesses that otherwise look nothing alike on paper.

How to Calculate EBITDA: A Step-by-Step Example

You calculate EBITDA by starting with net income from the financial statements and adding back interest, taxes, depreciation, and amortization, each pulled directly from the profit and loss statement.

Here is how that looks for a precision metal fabrication business doing $8.2 million in annual revenue.

Net income: $620,000
Add back interest expense: $180,000 (bank term loan on CNC equipment)
Add back income taxes: $210,000
Add back depreciation: $340,000 (machinery and equipment)
Add back amortization: $40,000 (capitalized ERP software)

EBITDA: $1,390,000

That is it. No adjustments yet, no judgment calls, just addition. This raw EBITDA figure does not yet tell a buyer what the business is worth, since it still includes one-time items and owner-specific expenses sitting inside that net income figure. That is where adjusted EBITDA comes in.

04 · Buyer View

Adjusted EBITDA: The Number Buyers Actually Use

Adjusted EBITDA, also called normalized EBITDA, takes raw EBITDA and further adjusts for expenses or income that would not carry forward to a new owner. This is the number that actually shows up in a letter of intent, not raw EBITDA.

The most common legitimate adjustments include:

• Above-market owner compensation. If the owner pays themselves $400,000 and a market-rate general manager would cost $150,000 to run the same operation, the $250,000 difference gets added back.
• One-time legal expenses. A lawsuit settlement or a one-off contract dispute that will not recur gets added back, provided it is genuinely non-recurring and documented.
• Personal expenses run through the business. A vehicle used personally, a family member on payroll who does not work in the business, or travel unrelated to operations. Common in smaller businesses, and buyers expect to see some of it.
• A non-recurring move or relocation. The cost of relocating a facility or a one-time system conversion that will not happen again.
• Related-party rent adjusted to market. If the owner also owns the building and charges the business rent above or below what an unrelated landlord would charge, that difference gets normalized in either direction.

Buyers and their advisors accept adjustments that are specific, documented, and genuinely non-recurring. They push back on vague entries like "miscellaneous," on expenses claimed as one-time that show up three years running, and on owner compensation add-backs with no market data behind them. An add-back you cannot document with an invoice, a payroll record, or a comparable market rate is one a buyer's advisor will strike before they calculate your price.

EBITDA vs. SDE: Which One Applies to Your Business?

The difference comes down to who runs the business day to day. SDE, or Seller's Discretionary Earnings, adds back the full compensation of one working owner, while EBITDA assumes a market-rate manager is already in place drawing a market salary. That single distinction is why the same business can produce two very different numbers, and why neither one is wrong.

SDE is the standard for owner-operated businesses, typically those where the owner is actively working full time and the business could not run tomorrow without replacing that labor. EBITDA is the standard for businesses large enough to already have, or easily support, a management layer that runs operations independent of the owner. The convention generally shifts somewhere around $1 million to $2 million in annual earnings, though the real trigger is not the dollar figure. It is whether the business already runs on a management team or still runs on the owner.

Here is the same HVAC company valued both ways. The business generates $2.4 million in revenue. The owner works full time as the general manager and draws a $140,000 salary, plus the business covers his truck and phone, worth another $15,000 a year.

To calculate SDE, you start with net income and add back the owner's full salary and personal benefits, along with interest, taxes, depreciation, and amortization. Say that totals $380,000. That is SDE: the full financial benefit available to an owner who works in the business exactly the way the current owner does.

To calculate EBITDA, you start with that same $380,000 and subtract what it would cost to hire a general manager to do the owner's operating job, roughly $95,000 in most markets for a business this size. Adjusted EBITDA comes out to $285,000.

SDE assumes the buyer will step in and work the business personally, the way most individual buyers intend to. EBITDA assumes the buyer will hire someone to run it, the way a private equity buyer or strategic acquirer with existing management typically will. The number you lead with depends on who you expect your buyer to be.

EBITDA vs. Net Income vs. Cash Flow vs. Free Cash Flow

Each of these four numbers answers a different question, and using the wrong one to make a decision is a common and expensive mistake.

Net income is the bottom line after every expense, including interest, taxes, depreciation, and amortization. It is shaped so heavily by financing and tax decisions that it can hide the underlying operating trend.

EBITDA strips out financing and tax effects to show operating performance on a comparable basis, but it hides the capital expenditures and working capital swings covered later in this article.

Operating cash flow captures the actual cash moving through the business, including the working capital swings EBITDA ignores. It is closer to reality, but still does not account for the capital expenditures needed to replace aging equipment or vehicles.

Free cash flow, operating cash flow minus capital expenditures, is the number closest to what an owner can actually pull out of the business without slowly starving it of the assets it needs to keep operating. It is the least commonly quoted of the four and the most honest.

How EBITDA Multiples Work in a Sale

A buyer arrives at a purchase price by multiplying your adjusted EBITDA by a multiple that reflects risk, growth, and industry demand. The same EBITDA dollar can be worth very different amounts depending on what drives that multiple, customer concentration, recurring revenue, owner dependency, growth trends, and industry conditions among them. The EBITDA figure is only the starting point; the multiple is where most of your value actually gets negotiated. How multiples get set and what buyers look for is covered in depth elsewhere in this series.

What EBITDA Doesn't Tell You: The Honest Criticisms

EBITDA ignores four things that determine what an owner actually gets to keep: the capital expenditures required to maintain the business, the working capital needed to fund growth, the real cost of servicing actual debt, and the asset intensity of the business itself. Say it plainly: EBITDA can flatter a business that requires heavy, ongoing reinvestment just to stay in place.

A regional trucking company is the clearest example. It might report $900,000 in EBITDA, a number that looks strong on paper. But its fleet of 18 tractors, averaging six years old, will need eight replaced within three years at roughly $150,000 each, a $1.2 million capital expense EBITDA never mentions. The owner is not pocketing $900,000 a year; a meaningful share has to go back into the fleet, and a buyer who values the business on EBITDA alone without accounting for that replacement cycle will overpay.

Working capital creates a similar blind spot: a growing manufacturing business often needs to fund more inventory and carry more in receivables before the cash from that growth shows up in the bank, and EBITDA does not capture that drain. Interest, the very thing EBITDA adds back, is still a real payment coming out of the business every month if that debt needs to be serviced. Adding it back for comparison purposes does not make the payment optional.

None of this means EBITDA is useless. It means EBITDA is a starting point for comparison, not a final answer about what a business, or a buyer, actually gets to keep.

EBITDA Margin: A Useful Benchmark, With Real Limits

EBITDA margin is EBITDA divided by revenue, expressed as a percentage, and it lets you compare operating profitability across businesses of different sizes within the same industry. A business generating $500,000 in EBITDA on $10 million in revenue has a 5 percent margin; the same $500,000 on $2.5 million in revenue is a 20 percent margin, a difference that says a great deal about how efficiently each business turns revenue into earnings.

Margin benchmarks vary enormously by industry, which is why comparing your margin to your own industry matters more than to a number you saw elsewhere. An online business selling digital products might run EBITDA margins of 30 to 40 percent, with almost no inventory or physical facility, while a manufacturing business in the same revenue range might run 10 to 18 percent because of raw material costs, equipment, and labor-intensive production. The comparison that matters is always against your own industry, not across industries.

How to Calculate Your Own EBITDA

Start with net income from a CPA-prepared financial statement, then add back interest expense, income tax expense, depreciation, and amortization as they appear on your profit and loss statement and fixed asset schedule. That gives you raw EBITDA; adjusted EBITDA takes more work and more documentation.

To do this properly, you will need at least three years of financial statements and tax returns, a general ledger detailed enough to identify one-time and personal expenses, a fixed asset schedule showing depreciation by asset, loan statements showing interest expense, and payroll records showing owner and family compensation. If you own the real estate separately and charge the business rent, you will need that lease and market comparables to support the adjustment.

A rough EBITDA calculation is useful for your own planning or a preliminary conversation with an advisor, but it is not what you take to a buyer. Once you are preparing to go to market, have a CPA experienced in transactions, or an M&A advisor working alongside your CPA, document your adjusted EBITDA properly. A number you cannot defend during due diligence will get renegotiated downward at the worst possible time in the process.

This article explains EBITDA in general terms, not tax or accounting advice. How EBITDA and its add-backs interact with your specific entity structure, depreciation elections, and tax filings should always be reviewed with your CPA before you rely on the number.

Common Mistakes Business Owners Make When Using EBITDA

• Treating raw EBITDA as the number a buyer will actually pay on. Buyers negotiate off adjusted EBITDA, and every add-back you have not documented gets challenged or removed before a price gets set.
• Confusing SDE and EBITDA and presenting the wrong one to the wrong buyer. An individual buyer looking to run the business personally thinks in SDE terms. A private equity buyer or strategic acquirer with existing management thinks in EBITDA terms, and leading with the wrong number creates confusion and erodes trust early in a conversation.
• Ignoring the capital expenditures sitting behind depreciation. Depreciation is added back because it is non-cash, but the equipment it represents still wears out and still needs to be replaced with real cash at some point.
• Padding the add-back list with expenses that are not truly one-time. An expense claimed as non-recurring that shows up on three consecutive years of tax returns is not one-time, and a buyer's advisor will catch it.
• Leaving related-party rent unaddressed. Paying yourself above or below market rent through a real estate entity you own distorts EBITDA in either direction and needs to be normalized before the number means anything to an outside buyer.
• Comparing your EBITDA margin to a completely different type of business. A manufacturing business and an online business will never carry the same margin profile, and benchmarking against the wrong peer group leads to false conclusions about your own performance.
• Waiting until a buyer is already in due diligence to calculate EBITDA for the first time. By then there is no time to gather documentation, and unsupported numbers get renegotiated downward under pressure instead of being resolved calmly ahead of time.
