A valuation multiple is only ever half of a number — it has to be applied to an earnings figure, and manufacturing deals use two of them: SDE and EBITDA. Owners get tangled here more than anywhere else, and the tangle is expensive, because comparing a multiple quoted on one measure to a multiple quoted on the other is how an owner talks themselves into a figure the market never offered. This is general education, not legal, tax, or financial advice; a CPA, a certified business appraiser, and an M&A advisor reading your real numbers are who decide which measure fits your business and what it is worth.
You do not need to be selling to want this straight. Understanding which earnings measure your shop would be valued on, and why, is part of reading the market honestly — and it is what keeps a quoted multiple from becoming a story you tell yourself. So before any number means anything, it is worth being precise about the two measures underneath it.
SDE: what it measures and who it fits
Seller’s discretionary earnings (SDE) takes the business’s profit and adds back the owner’s salary, benefits, and discretionary expenses. It answers a specific question: what does this business produce for one owner-operator who works in it? That framing is why SDE is the common measure for smaller, owner-run shops — roughly those under one to two million dollars of owner earnings — where the owner is central to quoting, scheduling, and the customer relationships, and where the owner’s pay is genuinely part of what the business throws off.
Because SDE adds the owner’s pay back, it is the larger of the two earnings figures, and an individual buyer or an SBA-backed search buyer reads it that way: they are buying a job and a cash flow, and they underwrite conservatively. That is part of why the multiples quoted on SDE sit lower than the multiples quoted on EBITDA — a point that trips up more owners than any other.
EBITDA: what it measures and who it fits
EBITDA — earnings before interest, taxes, depreciation, and amortization — measures the business’s earnings with a hired management team already in place. It does not add the owner’s pay back, because it assumes the owner’s seat is filled by a paid manager the buyer inherits or hires. That makes EBITDA the smaller earnings figure, and the right measure for larger plants and most private-equity and strategic acquisitions, where the buyer is not stepping into the owner’s chair and the business already runs on a bench rather than one person.
Because EBITDA is the smaller number, the multiples quoted on it run higher than SDE multiples — not because the business is worth more, but because the math has to land at roughly the same enterprise value from a smaller starting figure. Keeping that straight is the whole game.
The crossover, and the trap of comparing the two
Advisory commentary, including from firms such as Sofer Advisors and the pattern visible in BizBuySell’s sold-business data, often puts the crossover between the two measures near two million dollars of EBITDA — below it the deal usually speaks SDE, above it the deal usually speaks EBITDA. Treat that as a directional marker, not a hard line: where a specific business sits depends on how much it leans on the owner versus a management bench, which is a judgment your advisors make from the real numbers.
The trap is comparing the measures as if they were the same. Because SDE adds the owner’s pay back and EBITDA does not, the same business shows a larger SDE figure and a smaller EBITDA figure — and the multiples move in the opposite direction to keep the value consistent. So an EBITDA multiple that sounds higher than an SDE multiple is not automatically a better outcome, and a number you hear at a trade show or read in a headline is meaningless until you have asked the only question that matters first: which earnings measure is this multiple sitting on?
What the market ranges actually say
With that distinction in hand, the reported ranges become readable rather than misleading. The BizBuySell marketplace, which tracks completed small-business sales, has reported an all-industry median selling price on the order of 2.7 times SDE in recent quarterly insights, with manufacturing among the stronger categories. Advisory commentary from M&A firms such as CT Acquisitions and The Precision Firm puts general, owner-operated machine shops in a rough 3 to 5 times SDE range, broader lower-middle-market manufacturing nearer a 5 to 7 times EBITDA consensus, while research-style sources such as First Page Sage and valuation platforms like Equidam report manufacturing averages in a wider 4.5 to 8 times EBITDA band, scaling with size from roughly 4 to 6 times for the smallest businesses upward.
Notice that the SDE ranges and the EBITDA ranges are quoted on different earnings figures — which is exactly why you cannot stack them against each other. Read them as reported industry ranges that vary by source, methodology, and deal size, and as a way to understand the drivers, never as a valuation of your operation. A figure pulled from a chart and applied to your revenue without first settling which earnings measure it belongs to is a guess dressed up as a number.
Real-World Scenario: Two shops post the same annual revenue and, after the books are normalized, the same true earning power. One is run hands-on by its owner, who quotes the jobs and holds the customer relationships, so it is valued on SDE and the owner’s pay is added back into the earnings a buyer reads. The other already runs on a plant manager and a full management team, so it is valued on EBITDA, with that management cost already subtracted. The two land at a similar enterprise value, but they get there on different earnings figures and therefore different-looking multiples — and an owner who compared the SDE multiple of the first to the EBITDA multiple of the second, without noticing the measures differ, would badly misread which shop the market valued more.
From earnings measure to a defensible number
Knowing which measure fits is the start of a real valuation, not the end of one — the figure itself belongs to professionals who can read your actual financials. A CPA normalizes the earnings and handles the add-backs and tax, a certified business appraiser or M&A advisor builds a defensible value from the right measure for your size, and an attorney handles the structure and what transfers. Their work turns “roughly the industry range” into “this business, this number.”
The earnings measure is only one lever, so it is worth reading it alongside how certifications drive manufacturing valuation and who buys machine shops and manufacturers, and against the full picture in what your machine shop or manufacturing business is worth. The insurance side meets the deal quietly: the general liability and products-liability loss runs a buyer reads are part of what shapes the deal, and the new policy has to be issued to the entity that actually closes. When you are ready to make sure the operation is insured to the way it actually runs, start a quote. This is general education to sharpen the conversations with your own CPA, appraiser, and M&A advisor — not a substitute for their advice on your specific business.
