Business valuation is the process of estimating the economic worth of a company, a business unit, or its equity. In M&A it underpins the price a buyer is willing to pay and the price a seller is willing to accept; in finance more broadly it underpins fund accounting, fair-value reporting, estate planning, litigation and shareholder disputes. Practitioners rarely rely on a single number. Instead they triangulate across several methods — and several scenarios within each method — to produce a defensible range.

The three approaches

Valuation methods fall into three classic approaches. The right combination for any given engagement depends on the company's stage, industry, profitability, deal context and the standard of value being applied.

Income approach

Values a business by the cash it is expected to generate, discounted for time and risk. The dominant technique is the discounted cash flow (DCF), an intrinsic method based on the firm's own projected free cash flows and a discount rate (WACC) that reflects the riskiness of those flows. A DCF is highly sensitive to assumptions about growth, margins, capex and terminal value — small changes in inputs produce large changes in output, which is why a DCF is almost always paired with sensitivity tables and scenario ranges rather than presented as a single point estimate.

Market approach

Values a business relative to what the market pays for similar companies:

  • Comparable company analysis ("trading comps") — multiples of similar public companies, typically EV / EBITDA, EV / Revenue and P/E. Trading comps reflect minority-stake valuations and exclude any control premium.
  • Precedent transaction analysis ("deal comps") — multiples paid in past acquisitions of similar businesses. Precedents embed a control premium and the deal-specific synergies an acquirer was willing to pay for.

In the lower-middle market and main street segments, the market approach is the dominant valuation method — businesses are usually valued at a multiple of EBITDA or, for owner-operator-scale deals, a multiple of SDE. The multiple comes from observed deal flow in the segment rather than a formal trading-comp set.

Asset (cost) approach

Values a business by its assets net of liabilities. Variants include book value, adjusted net asset value (book values revised to fair market values) and liquidation value. Asset-based valuation is most relevant for:

  • Asset-heavy businesses where earnings are volatile but assets are tangible (real estate, equipment, inventory).
  • Holding companies and conglomerates (often combined with sum-of-the-parts valuation).
  • Distressed businesses where going-concern value has collapsed below liquidation value.
  • Financial institutions where book value is a meaningful market reference point.

For a healthy operating company, the asset approach generally produces the lowest of the three valuations because it ignores the value of intangibles such as customer relationships, brand and assembled workforce — the things that drive goodwill in an acquisition.

The "football field"

Because each method yields a different figure, bankers summarise the results on a football field chart — a set of horizontal bars showing the valuation range implied by each method. The chart usually displays:

  • 52-week trading range (for public targets).
  • Trading comps range (typically the lowest band).
  • Precedent transactions range (typically above trading comps because of the control premium).
  • DCF range (often the widest band, depending on terminal-value assumptions).
  • 52-week premium analysis or analyst price targets (where relevant).
  • For LBO-able targets, an LBO valuation reflecting what a financial sponsor would pay to hit a target IRR.

Overlap among the bars suggests a defensible negotiating range. The recommendation that emerges is rarely a single number — it is a range with an explanation of which methods support its low and high ends.

Standards of value

The "right" value depends on the standard of value being applied:

  • Fair market value — the price at which a hypothetical willing buyer and willing seller, neither under compulsion and both reasonably informed, would transact. Standard for tax, gift, estate and most non-strategic contexts.
  • Fair value — used in accounting (ASC 820, IFRS 13) and in some legal contexts including dissenting-shareholder appraisal proceedings. Definitions differ between accounting and legal use.
  • Investment value — worth to a specific buyer with that buyer's particular synergies, financing, tax position and strategic context. Investment value can exceed fair market value, which is why competitive sell-side processes routinely clear at prices above any fair-market-value estimate.

The same business will often have meaningfully different fair-market and investment-value figures. Sell-side practitioners use this gap deliberately — by bringing strategically motivated buyers into a process, they convert investment value into realised price.

Enterprise value versus equity value

Most M&A valuation is expressed first as enterprise value (EV) — the value of the whole operating business, independent of how it is financed — and then bridged to equity value by subtracting net debt and other claims:

Equity value = Enterprise value − Debt + Cash − Preferred − Minority interest − Pension underfunding − Other debt-like items

Mixing these up is one of the most common valuation errors. EV/EBITDA and EV/Revenue multiples are enterprise multiples; P/E is an equity multiple. When comparing methods on a football field, all bars must be expressed on the same basis (usually EV).

How values are normalised: adjusted EBITDA and SDE

Reported earnings rarely match the run-rate earnings a buyer is paying for. Practitioners apply normalisation adjustments — non-recurring items, owner-specific expenses, market-rate compensation, related-party transactions — to produce adjusted EBITDA or, in owner-operator businesses, seller's discretionary earnings. The adjusted figure is the denominator on which the multiple is applied. Sell-side advisors increasingly commission a quality-of-earnings report (QofE) before going to market to defend the adjusted figure to buyers.

Choosing the right method

The right method (and weighting) depends on the business and the deal context:

Business profile Primary method Supporting methods
Mature, profitable, predictable DCF + EV/EBITDA comps Precedents
Lower-mid-market, $1M–$10M EBITDA EV/EBITDA precedents EV/EBITDA comps, DCF as cross-check
Owner-operator, sub-$1M EBITDA SDE multiple from precedents Asset value as floor
High-growth, unprofitable EV/Revenue precedents and comps DCF with extended horizon
Asset-heavy / cyclical Asset-based + EV/EBITDA mid-cycle DCF
Distressed Liquidation / break-up value Going-concern DCF if turn-around plausible
Financial institution Book value, P/B comps Dividend-discount model
Holding company / conglomerate Sum-of-the-parts Discount applied to SOTP

Common adjustments and their typical magnitude

A clean valuation engagement applies four sets of adjustments:

  1. Normalisation adjustments to EBITDA — owner compensation to market, one-time items, related-party rent, discontinued lines. Typical magnitude: 5–25% of reported EBITDA.
  2. Working-capital adjustment — at closing, the seller delivers a normalised level of working capital. Variances above or below the target move price dollar-for-dollar.
  3. Net-debt adjustment — converting EV to equity. Includes capital-lease obligations, contingent liabilities and underfunded pensions.
  4. Control premium / minority discount / DLOM — applied where the standard of value or the share class differs from the comparable set.

Common valuation mistakes

The mistakes that cause the most damage are remarkably consistent:

  • Picking the wrong comparable set — small public companies in the same industry can be wildly different businesses from the private target.
  • Using stale precedents — multiples shift with the credit cycle; precedents older than three to four years should be re-cut.
  • Mixing EV and equity multiples, particularly when comparing across methods.
  • Over-weighting the DCF without disclosing that 60–80% of the value comes from terminal value, which is typically derived from the same multiples already in the comp set.
  • Ignoring QofE adjustments — taking management EBITDA at face value and discovering the real number 60 days into diligence.
  • Building synergies into the standalone valuation — synergy value belongs in the negotiating range, not the standalone DCF.
  • Confusing investment value with fair market value — every buyer thinks the seller's business is worth more in their hands; only the actual auction settles whose investment value gets paid for.

Frequently asked questions

What is business valuation?

Business valuation is the analytical process of estimating the economic worth of a company or its equity. It uses three classic approaches — income (DCF), market (multiples) and asset-based — and almost always produces a range rather than a single number.

How do you value a business?

Most practitioners triangulate across at least three methods: a DCF anchored on free-cash-flow projections and WACC; a comparable-company analysis based on multiples of similar public companies; and a precedent-transaction analysis based on multiples paid in similar acquisitions. The output is a "football field" of overlapping ranges from which a defensible negotiating range emerges.

What is the most accurate valuation method?

There is no single "most accurate" method — every method makes different assumptions and is more or less appropriate for different businesses. For mature, profitable companies the DCF is usually treated as the most rigorous, but it is also the most assumption-sensitive. The market approach (comps and precedents) is more defensible because it anchors to observed transactions, but only when the comparable set is genuinely comparable.

What is a typical EBITDA multiple?

Multiples vary widely by industry, size, growth and quality of earnings. Lower-middle-market private businesses typically trade at 4–8× adjusted EBITDA; owner-operator businesses at 2–4× SDE; mid-market businesses at 6–12×; high-quality, recurring-revenue businesses (SaaS, subscription home services) often above 10×. See the Home-Services M&A Multiples Report for current ranges in lower-middle-market home-services M&A.

What is the difference between enterprise value and equity value?

Enterprise value is the value of the entire operating business, independent of capital structure. Equity value is what shareholders own — enterprise value minus net debt and similar claims. EV/EBITDA is an enterprise multiple; P/E is an equity multiple.

What is a "football field" valuation?

A bar chart that summarises the valuation ranges produced by each method (DCF, trading comps, precedents, LBO) on a single page. Overlap among the bars defines the defensible negotiating range. Bankers use it to anchor price discussions in board meetings and fairness opinions.
