How Established Businesses Are Valued: The Main Methods

Ask three advisers what a founder-led company is worth and you'll often get three numbers. That's not incompetence. A private business has no daily share price, so its value is an estimate built from evidence, and the estimate changes with the method, the purpose and the person asking.

This article explains the toolkit professionals use. It covers the three valuation approaches, how earnings get "normalised" before any method is applied, why SDE and EBITDA aren't interchangeable, what "value" even means (it depends on who's buying), and how discounts and owner dependence change the result. It's a reference for owner-CEOs preparing for an exit, a buyout, a partner dispute or a tax filing. It isn't a substitute for a qualified valuer, and it deliberately doesn't print "typical multiples", because those vary by sector, size, period and deal, and a stale number does more harm than none.

Why a private company's value is an estimate

For a listed company, the market prices every share every second. A closely held company has no such price. The US tax authority described the problem in its guidance on valuing the stock of closely held corporations: the shares are owned by a relatively limited number of people, so there is no established market, and the sales that do occur seldom reflect all the elements of a representative transaction. The same ruling adds that valuation "is not an exact science" and that common sense, informed judgment and reasonableness have to enter the process (Rev. Rul. 59-60, full text).

Two practical consequences follow. First, valuers triangulate: they apply more than one method and reconcile the results rather than trusting a single formula. Second, the purpose of the valuation matters. A number prepared for a divorce settlement, a share-option scheme, a sale to a competitor and an internal buyout can legitimately differ, because the question being answered differs. Standards bodies treat this seriously: the International Valuation Standards Council describes its standards as covering bases of value, valuation approaches and methods, which is why a competent report always states what kind of value it's measuring and why.

For general background on the concept, see valuation.

The three approaches at a glance

Almost every business valuation method falls into one of three families. They ask different questions.

Rev. Rul. 59-60 lists the same building blocks in older language: earning capacity, the book value and financial condition of the company, goodwill, and the market price of comparable companies. It also says the weight each gets depends on the case. In general, it says, appraisers give primary consideration to earnings when valuing companies that sell products or services to the public, while for investment or holding companies the greatest weight may go to the underlying assets (full text). That logic still holds today.

The income approach

The income approach values a business by what it will earn. Two methods dominate.

Discounted cash flow (DCF)

A DCF forecasts the free cash flow the business will generate over an explicit period, usually several years, then adds a terminal value for everything after. Each year's cash is discounted back to today at a rate that reflects the risk of receiving it. A riskier business gets a higher discount rate and therefore a lower value.

DCF's strength is that it forces explicit assumptions about growth, margins, reinvestment and risk. Its weakness is the same thing: small changes in the discount rate or terminal assumptions swing the result a lot, and a forecast prepared by the seller invites optimism. The more a founder's relationships drive the forecast, the less a buyer will believe it.

Capitalisation of earnings

For a stable, mature business, a simpler version often suffices. Take a single representative level of annual earnings (normalised, as described below) and divide it by a capitalisation rate, which is the discount rate minus expected long-run growth. A lower capitalisation rate means a higher multiple of earnings.

Rev. Rul. 59-60 is candid about the hard part. It says determining the proper capitalisation rate is "one of the most difficult problems in valuation" and that no standard tables can be formulated for closely held corporations. It points to the nature of the business, the risk involved and the stability or irregularity of earnings as the main influences on the rate (full text). It also warns against mechanical averaging: arbitrary five-or-ten-year averages applied without regard to current trends or future prospects won't produce a realistic valuation.

The market approach

The market approach prices a business by reference to what others have paid or what the market pays for similar ones. It comes in two flavours.

Guideline (comparable) public companies. You look at listed companies in a similar line of business, work out how the market prices them (for example, enterprise value divided by EBITDA), and apply a similar ratio to the subject company, adjusted for differences. Rev. Rul. 59-60 supports the idea but insists on real comparability: a company with a declining business and decreasing markets, for instance, isn't comparable to one with a record of progress and market expansion. For most small and mid-sized private companies, listed peers are far larger and more diversified, so the adjustments are heavy.

Precedent transactions. You look at actual sales of private businesses of similar type and size, and derive multiples from them. This reflects what real buyers paid for control, which is closer to what an owner selling the whole company cares about. The practical obstacles are data quality and disclosure: many private deals don't publish prices or terms, and the headline price often hides earn-outs, deferred consideration or working-capital adjustments.

Whichever source is used, the multiple is only as good as the earnings number it's applied to. That brings us to the step most owners underestimate.

Normalising earnings: add-backs and adjustments

Reported profit in a founder-led company often isn't a clean picture of what a new owner would earn. Normalisation restates earnings to show the business as a buyer would run it. Typical adjustments include:

• Owner compensation. If the founder pays themselves far above or below what a replacement manager would cost, the difference is adjusted to a market-level salary for the role.
• Personal or discretionary expenses run through the company (vehicles, travel, family payroll for roles that don't exist) that a buyer wouldn't continue.
• One-off items: a lawsuit settlement, a large bad debt, a fire, a one-time consulting project. Rev. Rul. 59-60 makes the same point, saying an appraiser should be able to separate recurrent from nonrecurrent items of income and expense and to distinguish operating income from investment income (full text).
• Non-operating assets and income, such as idle property or an investment portfolio, which are valued separately from the operating business.
• Related-party arrangements at non-market rates, such as rent paid to the founder's own property company or below-cost services supplied by a relative.

Add-backs cut both ways. Some adjustments increase earnings (removing a personal expense), but others reduce them (paying a market salary to a manager the founder never paid because the founder did the job for free). A buyer's due diligence will test each add-back, and every one that can't be documented gets challenged or disallowed. The same discipline applies in venture settings; see startup due diligence for how scrutiny works from the buyer's side.

SDE versus EBITDA

These two earnings measures are applied to different kinds of company, and mixing them up is a common source of bad numbers.

The key difference is how the owner is treated. EBITDA charges the business a fair cost for management, so it measures what a hired-management business earns. SDE leaves the owner's work in the profit, so it measures what a hands-on owner can take home. A multiple derived from SDE deals can't be applied to EBITDA, or vice versa, without distorting the result. If a quoted multiple doesn't say which earnings measure it sits on, treat it with suspicion. For the definition and mechanics of EBITDA, see EBITDA.

This is also where the founder's role shows up in the numbers. A company that can only earn its SDE if the founder keeps working is, in effect, selling a job. A company that earns its EBITDA with a management team in place is selling an asset.

The asset approach

The asset approach values the business as the sum of its parts. The usual method is adjusted net asset value: restate each asset and liability from its book figure to fair value, then subtract liabilities from assets. Property might be revalued to market, inventory written down if obsolete, and intangible assets that appear nowhere on the balance sheet (customer lists, software, brands) added at estimated value.

Rev. Rul. 59-60 says that for a holding or real-estate company, adjusted net worth should be accorded greater weight than earnings or dividends. It also treats goodwill as a function of earning capacity: its value rests on the excess of net earnings over a fair return on net tangible assets (full text). That's the link back to the income approach. Where earnings are strong, the asset approach gives a floor, and the gap above it is goodwill. Where earnings are weak, the asset approach may be the best evidence of value, and a liquidation basis can be the relevant premise.

The asset approach is rarely the headline method for a profitable services or technology business, because most of its value sits in people, relationships and know-how that don't appear as assets.

What kind of value? Standards of value

Before choosing a method, the valuer has to settle the standard of value, meaning whose perspective defines "worth".

Fair market value. This is the standard used in US tax law. The regulations define it as the price at which property would change hands between a willing buyer and a willing seller, neither under compulsion and both with reasonable knowledge of relevant facts (26 CFR 20.2031-1). The rule for business interests uses the same test and tells valuers to weigh all relevant factors, including a fair appraisal of all assets (tangible and intangible, including goodwill) and the demonstrated earning capacity of the business (26 CFR 20.2031-3). Fair market value is hypothetical: it asks what a typical buyer would pay, not what your best-matched buyer would.

Strategic (investment) value. This is the value to a specific buyer, including benefits only that buyer can capture, such as cost savings, cross-selling or removing a competitor. It can sit well above fair market value, which is why a competitor or a well-matched acquirer may outbid financial buyers. The strategic vs financial buyers article covers how this plays out in a sale process, and private equity explained covers how financial buyers think about price and leverage.

An owner who hears "your business is worth X" should always ask which standard X refers to. A valuation for a share transfer between partners and the price a strategic acquirer will pay are different questions with different answers.

Discounts and premiums

After the base value is estimated, valuers often adjust it for the characteristics of the specific ownership interest being valued.

• Control and minority. A controlling interest can set strategy, pay dividends, sell the company and change management. A minority holder can't. Rev. Rul. 59-60 acknowledges both sides: a minority interest in an unlisted company is more difficult to sell than a similar block of listed stock, while control, representing an added element of value, may justify a higher value for a specific block (full text). In practice that's expressed as a discount for lack of control (DLOC) or a premium for control, depending on how the base value was derived.
• Marketability. Shares in a private company can't be sold quickly at a known price. A discount for lack of marketability (DLOM) reflects that illiquidity. Whether and how much to apply depends on the standard of value, the jurisdiction, the facts and the valuer's judgment, and it's often contested in disputes. This article doesn't give a percentage because no single figure is safe to quote.
• Order of application. Discounts apply to different bases. A value built from control-level transactions may need a control adjustment before a minority interest is priced; a value built from minority public-market data may not. Applying a discount twice, or to the wrong base, is a common error.

For a 100% sale of a company to an acquirer, these discounts typically play little role, because the buyer is paying for control. They matter most in minority transfers, partner buyouts, gifting and estate planning, and disputes between shareholders.

Why owner dependence changes the number

Valuation methods are mechanical. The inputs aren't, and the founder is usually the biggest input. Rev. Rul. 59-60 addresses this directly: the loss of the manager of a so-called "one-man" business may have a depressing effect on the value of its stock, particularly where there's a lack of trained personnel able to succeed to management. It tells the valuer to weigh the effect of that loss on future expectancy and the absence of management-succession potential, and also to weigh offsetting factors such as life insurance or the ability to hire competent management (full text).

The mechanism works through the formulas in three ways:

1. Earnings quality. If profit depends on the founder's personal selling, relationships or technical skill, the normalised earnings a buyer will believe are lower, because a market-rate replacement has to be paid for.
2. Risk and the discount rate. Uncertainty about whether income continues raises the discount or capitalisation rate, which lowers value. The ruling states the principle: uncertainty as to the stability or continuity of future income decreases value by increasing the risk of loss.
3. Deal structure. Buyers often respond to dependence with earn-outs, deferred payments or a required founder transition period instead of cash at closing, so some of the headline price becomes conditional.

Customer and supplier concentration works the same way. If one customer accounts for a large share of revenue, the cash flows are less certain and the rate goes up. The practical fix is the same for both: reduce reliance on any single person or account before a sale. The articles on founder dependence and key person risk describe how to measure and reduce it.

Choosing and combining methods in practice

A sensible valuation for an established private company usually looks like this:

1. Fix the purpose and standard of value, and the date.
2. Normalise earnings and document every add-back.
3. Apply at least two approaches. For an operating business, that's typically a market multiple cross-checked against a capitalised-earnings or DCF figure, with the asset approach as a floor.
4. Reconcile the results and explain the weighting, rather than averaging mechanically. Rev. Rul. 59-60 says no useful purpose is served by simply averaging factors such as book value, capitalised earnings and capitalised dividends.
5. Apply any control or marketability adjustments appropriate to the interest being valued.
6. Stress-test the owner-dependence assumptions, since that's where buyers will push hardest.

If the purpose is a sale, a valuation is only the starting point. A buyer's price reflects negotiation, financing, competing bidders and fit, not just the output of a model. For ownership routes beyond a third-party sale, such as a management buyout, the same methods are used, but the price is also shaped by what the buying managers can finance.

Key Facts: Business valuation methods

• There are three families of method: income (DCF, capitalisation of earnings), market (comparable companies, precedent transactions) and asset (adjusted net asset value).
• Rev. Rul. 59-60 says valuation "is not an exact science" and that no general formula is applicable to all situations.
• The same ruling says determining the capitalisation rate is "one of the most difficult problems in valuation" and that no standard tables can be formulated for closely held corporations.
• US regulations define fair market value as the price between a willing buyer and a willing seller, neither under compulsion and both with reasonable knowledge of relevant facts.
• Rev. Rul. 59-60 states that the loss of the manager of a "one-man" business may depress the value of the stock, especially without trained personnel able to succeed.
• The IVSC says International Valuation Standards cover bases of value and valuation approaches and methods.
• SDE adds back the owner's whole compensation and suits small owner-operated businesses; EBITDA charges a market salary for management and suits larger ones. Multiples from one can't be applied to the other.
