The Number Everyone Wants — and Nobody Can Agree On
Ask a business owner what their company is worth and you'll get one number. Ask a potential buyer and you'll get a different one — usually 30 to 50 percent lower. Neither is making it up. They're simply looking at the same business through different valuation lenses, weighting different factors, and arriving at conclusions that reflect their respective positions.
This gap is not a failure of the process. It's a feature of it. Valuation is not a calculation with a single correct answer. It's an analytical exercise that produces a defensible range — and the rigor of that analysis determines whether the range holds up under scrutiny or collapses during negotiation.
Understanding how valuation actually works — not the shorthand version, but the real methodology — is the difference between walking into a deal with conviction and walking in with a guess.
Three Approaches, Not One
Professional business valuation relies on three standard approaches, each of which examines value from a different angle. A credible valuation considers all three and weighs them based on the nature of the business, the quality of available data, and the purpose of the valuation. Relying on a single approach — especially a rule-of-thumb multiple — is where the most expensive mistakes are made.
The Income Approach
The income approach values the business based on its expected future cash flows or earnings, discounted back to present value. The most common methods are capitalization of earnings (used for businesses with stable, predictable cash flows) and discounted cash flow (DCF) analysis (used when future growth or changing cash flows need to be modeled explicitly).
This approach answers the fundamental buyer question: "If I pay this price today, what return will I earn on my investment?" The discount rate — which reflects the risk of achieving the projected cash flows — is where much of the analytical judgment lives. A higher-risk business gets a higher discount rate, which produces a lower present value. A stable, well-documented business with recurring revenue earns a lower discount rate and, consequently, a higher valuation.
Why it matters: The income approach is the most commonly used method in M&A transactions because it directly reflects the economic value of the business to a buyer. It's also the method most sensitive to the quality of financial documentation — clean, audited financials produce more defensible valuations than reconstructed or estimated numbers.
The Market Approach
The market approach values the business by comparing it to comparable transactions — either publicly traded companies in the same industry (the guideline public company method) or private company sales of similar size and type (the comparable transaction method). The comparison typically uses multiples of earnings (EBITDA, SDE, or net income) or revenue to establish a valuation range.
This is where the "industry multiple" enters the conversation — and where it becomes dangerous. When an owner says "my industry trades at 4x EBITDA," they're referencing the market approach. But that 4x is an average across transactions that vary enormously in size, geography, growth rate, profitability, customer concentration, and a dozen other factors. A business with $800,000 in EBITDA, high customer concentration, and flat growth does not trade at the same multiple as a business with $3 million in EBITDA, diversified revenue, and 15% annual growth — even if both are in the same industry.
Why it matters: The market approach provides a reality check grounded in actual transactions. But it requires careful selection of truly comparable businesses and thoughtful adjustment for differences. An unadjusted industry average multiple is not a valuation — it's a starting point that requires significant refinement.
The Asset Approach
The asset approach values the business by calculating the fair market value of all its assets minus the fair market value of all its liabilities. This can be done on a going-concern basis (the business continues operating) or a liquidation basis (the assets are sold off individually).
For most operating businesses in the $1M–$30M revenue range, the asset approach produces the lowest valuation because it doesn't capture the earning power of the business — the intangible value of customer relationships, brand, systems, and the assembled workforce. However, it serves as an important floor: a business should generally be worth at least the net value of its tangible assets. When the income or market approach produces a value below the asset value, that's a signal worth investigating.
Why it matters: The asset approach is most relevant for capital-intensive businesses (manufacturing, distribution, real estate holding companies), businesses that are not profitable, or situations where the buyer intends to acquire the assets rather than the operating entity. It also establishes the tax basis for purchase price allocation in asset sales.
Why Rule-of-Thumb Multiples Are Dangerous
The most common valuation mistake in the lower middle market is relying on a single industry multiple as if it were a fact. An owner hears "construction companies sell at 3 to 5 times EBITDA" and mentally anchors on the high end. A buyer hears the same range and anchors on the low end. Neither has done the work to understand where this specific business falls within the range — or whether the range even applies.
A rule-of-thumb multiple doesn't account for owner dependency, customer concentration, the quality of financial records, the strength of the management team, revenue predictability, capital expenditure requirements, or any of the other factors that move a multiple up or down within its range. On a business with $1.5 million in EBITDA, the difference between a 3.5x and a 5x multiple is $2.25 million. That gap is not resolved by a conversation — it's resolved by analysis.
A rule-of-thumb multiple is not a valuation. It's a guess with the appearance of precision — and it's the starting point of most valuation arguments that cost business owners real money.
What a Proper Valuation Provides
A rigorous business valuation — whether it's a formal CVA opinion or a detailed summary valuation — does several things that a back-of-napkin multiple cannot. It identifies and adjusts for non-recurring items, owner compensation above market, and one-time expenses that distort true earnings. It benchmarks the business against actual comparable transactions, adjusting for meaningful differences. It models the specific risk profile of the business and translates that into a defensible discount rate. And it produces a documented analysis that can withstand buyer scrutiny, lender review, and — if necessary — legal challenge.
Perhaps most importantly, a proper valuation tells the owner not just what the business is worth, but why it's worth that number. That understanding is what makes the difference between walking into a negotiation with a number you hope is right and walking in with a range you can defend — because you know exactly what assumptions it's built on and what would change it.
The purpose of a valuation is not to produce the highest possible number. It's to produce the most accurate possible number — because an accurate number is the one that survives contact with a buyer, a lender, and a due diligence process. An inflated valuation that collapses during negotiation costs more than a conservative one that holds.
