Ask a hundred owners what their business is worth and most will reach for one of two anchors: a multiple of revenue they half-remember from a competitor who sold, or the number they need to walk away and never work again. Both are fictions. A business is worth its normalized earnings multiplied by a market multiple, and that multiple is set by how risky, how fast-growing, and how transferable the cash flow is. Learn the formula and the handful of value drivers behind it, and you can do two things most sellers never manage: price the business honestly, and raise the price before you ever take it to market.
The two anchors that wreck a sale
The first wrong anchor is revenue. An owner doing four million dollars in sales hears that "businesses sell for around one times revenue" and decides the company is worth four million. But revenue is not what a buyer takes home; earnings are. A four-million-dollar shop that nets one hundred thousand in owner cash is worth a fraction of a two-million-dollar shop that nets six hundred thousand. Top line tells you almost nothing about value until you know what falls to the bottom.
The second wrong anchor is need. An owner has done the retirement math, knows the number that funds the rest of their life, and quietly decides the business must be worth at least that. The market does not care what you need. It prices the cash flow and the risk attached to it, full stop. When the honest valuation lands below the retirement number, the answer is not to demand a higher multiple from buyers who will not pay it. The answer is to spend the next two or three years moving the drivers that actually set the multiple.
The formula: earnings times a multiple
Almost every Main Street and lower-middle-market business is valued the same way: take a measure of normalized annual earnings, and multiply it by a market multiple. For owner-operated businesses that earnings figure is usually SDE, seller discretionary earnings, which is net profit with the owner salary, perks, interest, taxes, depreciation, and one-time costs added back. For larger businesses with a management layer, buyers shift to EBITDA, earnings before interest, taxes, depreciation, and amortization. The structure is identical: earnings times multiple equals value.
The number people obsess over is the earnings figure, because it feels concrete and they can grow it by selling more. But the earnings figure is only half the equation, and on most deals it is the half that moves least year to year. The multiple is where value is won and lost. A business earning three hundred thousand can be worth six hundred thousand or one and a half million depending entirely on the multiple a buyer is willing to apply, and that multiple is a direct readout of risk, growth, and transferability.
A useful rule of thumb runs through all of it: smaller and more owner-dependent businesses trade lower, often in the rough range of two to three times SDE, while larger, cleaner, more systematized businesses trade higher, frequently four to six times EBITDA or more. BizBuySell closed-transaction medians and IBBA Market Pulse broker surveys both show the same shape, multiples climbing with deal size and with the quality of the earnings underneath. Treat these as defensible ranges, not precise quotes; the right multiple for a specific business comes from comparable closed sales in its sector and size band, not from a single headline number.
What actually moves the multiple
If earnings are the what, the multiple is the how much they trust it. Five drivers do most of the work. Each one is a question the buyer is really asking: how predictable is this cash flow, how dependent is it on you, where is it heading, how concentrated is the risk, and can I even verify the numbers. Move these and you move the multiple.
| Value driver | What the buyer is asking | Direction it moves the multiple |
|---|---|---|
| Recurring revenue % | Will the cash flow still be here next year without re-selling every customer? | Higher recurring share raises the multiple; one-off, project revenue lowers it |
| Owner dependence | Does the business run, or does it run on the owner? | Less owner dependence raises the multiple; an owner who is the salesperson, the relationship, and the operator lowers it |
| Growth trend | Is this line going up, flat, or quietly shrinking? | A credible upward trend raises the multiple; flat is neutral; decline cuts it hard |
| Customer concentration | What happens if the biggest account leaves? | A broad, diversified base raises the multiple; one customer at thirty percent or more lowers it |
| Clean, verifiable books | Can I trust and finance these numbers in due diligence? | Clean financials and tax returns that tie out raise the multiple; messy or cash-heavy books lower it and can kill the deal |
A three-step valuation walk-through
Pricing a business is not a black box. Work it in three steps, in order, and you arrive at a number you can defend to a buyer and their bank.
Put a number on it
The calculator below is the whole formula in two inputs: normalized earnings and a market multiple. It does the one piece of arithmetic that the rest of this article exists to inform, so that the number you walk away with reflects a defensible multiple rather than a hopeful one.
Run the defaults and the math is simple: three hundred thousand dollars of SDE multiplied by a market multiple of 3.2 gives an indicated value of nine hundred and sixty thousand dollars. Now notice where the leverage sits. The earnings figure is largely set by how the business performed last year and is hard to move quickly. The multiple is the part the value drivers control. Push that same three hundred thousand of earnings from a 3.2 multiple up to a 4.0 by building recurring revenue and removing yourself from daily operations, and the indicated value climbs to one million two hundred thousand, a two-hundred-and-forty-thousand-dollar gain on the identical profit. That is the entire argument of this article in one comparison: the multiple, not the earnings alone, is what risk and transferability move.
Why some sectors break the simple rule
The earnings-times-multiple formula is the default, but a few business types are valued on a different basis, and knowing which camp you are in matters. Asset-heavy, real-estate-like businesses such as self-storage are often valued by capitalizing net operating income rather than on an SDE multiple, because the income stream is tied to the property and runs largely on autopilot. Service trades like HVAC sit squarely in the multiple world, where signing customers to maintenance agreements converts one-off jobs into recurring revenue and visibly lifts the multiple a buyer will pay. And some categories, restaurants being the classic example, trade at thin multiples no matter how the food tastes, because the cash flow is fragile, owner-dependent, and easily disrupted. The formula still holds; the inputs and the defensible range simply differ by model.
For an owner two or three years out from a sale, the practical takeaway is that value is not a fixed fact you discover at the closing table. It is partly a number you build. The earnings will be what they will be, but the multiple is a scorecard of risk and transferability that you can study, target, and improve. Owners who treat the multiple as something done to them leave money on the table. Owners who treat it as a set of drivers to work on, starting well before they hang the sign, are the ones who sell at the top of the range.
