How Small Businesses Are Actually Valued

Most small businesses are valued as a multiple of their earnings — a buyer looks at what the operation reliably produces each year, applies a multiplier that reflects how risky and transferable those earnings are, and arrives at a price range. The math takes minutes. The number that comes out, though, is only as good as two inputs owners control long before a sale: which earnings figure the books can support, and how believable those books are.

The two earnings figures that anchor a valuation

Seller’s discretionary earnings (SDE) is the usual anchor for owner-operated businesses. It starts from profit and adds back everything that exists because of the current owner personally: their salary and benefits, discretionary perks run through the business, one-time expenses. SDE answers the question a buyer who will run the company themselves actually has — how much does this business generate for the person who owns and operates it?

EBITDA — earnings before interest, taxes, depreciation, and amortization — takes over for larger businesses that will keep professional management after the sale. It measures the operation without the current financing and accounting effects. (We wrote a full plain-English guide to EBITDA.)

The dividing line is roughly whether the buyer is buying a job plus an asset (SDE) or an investment that runs without them (EBITDA). Many small-business sales are discussed in SDE terms even when the listing says EBITDA — worth clarifying early in any conversation.

What moves the multiple

Multiples vary widely by industry, size, and deal — there is no universal chart, and anyone quoting your business a multiple without looking at it is guessing. But the direction of what moves multiples is consistent:

• Owner dependence. If revenue follows the owner’s personal relationships and skills out the door, earnings are riskier and the multiple compresses. Documented processes and a team that runs without daily heroics push it the other way.
• Revenue quality. Recurring contracts and repeat customers beat one-off project work. Concentration hurts: one customer being a large share of revenue is a discount waiting to happen.
• Earnings credibility. Clean, reconciled, consistent books get believed. Books that need explaining get discounted — or kill the deal in diligence.
• Trend. Three years of steady or growing earnings read very differently from one great year after two rough ones, even at the same average.

A simple illustration

Suppose an owner-operated business shows $250,000 of SDE, and businesses of its type and size have been changing hands somewhere between 2× and 3× SDE. That frames a range of $500,000 to $750,000 — a quarter-million-dollar spread decided almost entirely by the risk factors above. The hypothetical numbers matter less than the shape of the math: the multiple is where your operational choices get priced.

Where owners quietly lose value

The most common damage we see isn’t a bad business — it’s good earnings the books can’t prove. Personal expenses mixed into the P&L in ways nobody documented. Add-backs that live in the owner’s memory instead of a schedule. Prior years categorized three different ways, so trends look noisier than the business really was. Every one of those turns into either a lower offer or a longer, more invasive diligence process.

Our free Business Valuation Calculator gives you an educational starting range from your earnings and a multiple you choose. It is not an appraisal and no calculator replaces a professional valuation — but it’s the right way to frame the conversation before you talk to a broker, a buyer, or a lender. And if the earnings number itself is the shaky part, that’s a books problem before it’s a valuation problem: our cleanup service and executive reporting exist for exactly this.
