EBITDA vs. SDE: Which Number Actually Values Your Business?

SDE and EBITDA both measure your business’s true earning power, but SDE includes the owner’s compensation, while EBITDA excludes it. SDE is used to value smaller, owner-operated businesses where the buyer steps into the owner’s role. EBITDA is used for larger businesses run by a management team. Use the wrong one and you can misjudge your value by hundreds of thousands of dollars.

That single difference, whether the owner’s pay counts as profit or as an expense, is the whole story. Here’s why it matters so much, and which one applies to you.

The difference at a glance

If you only remember one row, make it the owner’s salary. That’s the lever that swings everything else.

What is SDE?

Seller’s Discretionary Earnings (SDE) is the total financial benefit a single owner-operator pulls from the business in a year. You build it by starting with net profit and adding back:

• The owner’s full salary and payroll taxes
• The owner’s benefits (health insurance, retirement contributions)
• Interest, taxes, depreciation, and amortization
• One-time and non-recurring expenses
• Personal or discretionary expenses run through the business

The logic: a buyer of a small, owner-operated business is buying a job and an income stream. They’ll step into the role you’re playing, so the money you currently pay yourself becomes money available to them. It belongs in the earnings number.

SDE is the standard metric for Main Street and lower-middle-market deals, the corner HVAC company, the two-truck plumbing shop, the solo-owner accounting practice, the boutique agency where the founder is still the rainmaker.

What is EBITDA?

EBITDA strips out financing and accounting decisions to show core operating profit, by adding back to net income:

• Interest
• Taxes
• Depreciation
• Amortization

Critically, EBITDA does not add back the owner’s salary. It treats owner and executive compensation as a real, ongoing cost of running the business, because in a company this size, it is. The next owner won’t personally do the work; they’ll pay a team to. So that payroll has to stay in the expense column to reflect what the business really costs to operate.

EBITDA is the language of larger lower-middle-market deals, private equity, and strategic acquirers. Once a business runs on a management team rather than on the owner, buyers switch to EBITDA because it reflects the company as a standalone, transferable asset.

What’s the main difference between EBITDA and SDE?

It comes down to one question: does the owner’s pay count as profit or as a cost? In SDE, it’s profit, because the buyer takes over the role. In EBITDA, it’s a cost, because the buyer keeps paying someone to do the role. Everything else is bookkeeping; this is the fault line.

It’s also why you can’t compare an SDE multiple to an EBITDA multiple directly. They’re measuring different things. A “3x” on SDE and a “5x” on EBITDA can describe nearly the same valuation, because the underlying earnings numbers aren’t the same.

Which one applies to your business?

There are two tests, and the second one matters more.

At what size does a business switch from SDE to EBITDA?

As a rule of thumb, businesses with under roughly $1M in normalized earnings are valued on SDE; above that, buyers shift to EBITDA. The line isn’t rigid, but it’s a reliable starting point. The more telling test is owner-dependence. Ask honestly: if I stepped away for 90 days, would the business run?

• If the answer is “no, it depends on me” → you’re an SDE business, and a buyer prices you as someone buying your job.
• If the answer is “yes, the team runs it” → you’re approaching an EBITDA business, and you’ll attract larger, better-capitalized buyers who pay stronger multiples.

That second test is the one to obsess over. Moving from an owner-dependent SDE business to a management-run EBITDA business is one of the single largest value-creating shifts an owner can make, it changes not just how you’re valued, but who shows up to buy and how much they’ll pay.

Why is my EBITDA lower than my SDE?

Because EBITDA subtracts the owner’s salary that SDE adds back, so the same business almost always shows a higher SDE than EBITDA. That’s expected, and it’s exactly why the two metrics use different multiple ranges. It also explains how one company can carry two very different price tags depending on which method a buyer applies.

Imagine a DFW commercial landscaping company with $350,000 in net profit and an owner paying themselves a $150,000 market-rate salary.

• On SDE, you add the salary back: earnings are ~$500,000. At a 3x SDE multiple, that’s a $1.5M valuation.
• On EBITDA, the salary stays as an expense: earnings are ~$350,000. At a 5x EBITDA multiple, that’s a $1.75M valuation.

Same company, two methods, two numbers, and the right method depends on whether the business genuinely runs without the owner. This is exactly why owners who quote themselves a number from a generic online calculator so often get blindsided in real negotiations. The metric has to match the business.

Do add-backs apply to both EBITDA and SDE?

Yes, both rely on normalizing earnings with add-backs. The difference is only that SDE adds back owner compensation and EBITDA does not. And in both cases, the add-backs have to survive scrutiny.

This is where owners hurt themselves. The instinct is to add back everything to inflate the number. The result is a bloated earnings figure that collapses under diligence, and a buyer who now distrusts the entire financial picture. A defensible add-back is documented, genuinely non-recurring or genuinely discretionary, and survives a CPA’s review. An aggressive add-back is a negotiating gift to the buyer, who gets to “discover” it, strip it out, and re-anchor the price lower while questioning everything else you’ve claimed. Conservative and clean beats inflated and shaky every time.

Which is better, EBITDA or SDE?

Neither, they’re the right tools for businesses at different stages, not competing methods. Smaller and owner-run? SDE. Larger and team-run? EBITDA. The mistake isn’t preferring one over the other; it’s applying the wrong one to your business and walking into a negotiation with a number that doesn’t hold. And if your goal is a bigger exit, the most valuable move is the one that carries you across the line between them: building a business that runs without you.
