Owners typically seek a valuation for one of several reasons: a potential sale, succession or exit planning, a partner buyout, estate or gift tax filings, divorce, ESOP administration, or a judicial proceeding. Each situation carries its own rules, standards, and expectations.
This article covers the three valuation approaches, the difference between enterprise value and equity value, the factors that push value up or down, and the steps an owner can take to prepare a valuation that holds up under scrutiny.
Key Takeaways
- Private company value depends on purpose, valuation date, and ownership interest—not a rule of thumb.
- Valuators weigh income, market, and asset-based approaches, then reconcile results with business-specific evidence.
- Enterprise value isn't walk-away proceeds; debt, cash, and ownership adjustments shape equity value.
- Formal valuations matter most when IRS, court, ESOP, or transaction requirements apply.
What Is a Privately Held Company Valuation?
A privately held company valuation gives an independent estimate of the worth of a business, or of a specific ownership interest in it, as of a particular date and for a particular purpose. The purpose matters more than most owners realize, because a valuation built for a family gift will not necessarily answer the question that a buyer or an ESOP trustee poses.
Private-company valuation is genuinely harder than valuing a public stock, and for good reason:
- No active market — there's no daily trading to signal price
- Limited comparable data — few truly similar private deals get disclosed
- Less public disclosure — financials aren't audited or filed with regulators in most cases
- Concentrated ownership — a handful of shareholders can distort incentives
- Transfer restrictions — buy-sell agreements or bylaws may limit who can buy shares and when
Under Rev. Rul. 59-60, the IRS defines fair market value as the price a willing buyer would pay a willing seller when neither party must act and both have reasonable knowledge of the relevant facts. That standard underlies most tax-driven valuations, but other standards of value also exist.
Not All Value Opinions Are Equal
There's a real difference between:
- An informal estimate — a back-of-envelope number based on a rule of thumb
- A broker's opinion of value — a likely sale price estimate, often used for listing purposes
- A formal valuation report — a supportable, documented conclusion prepared for a tax, legal, financial, or transaction purpose
The standard of value also shapes the outcome. Fair market value differs from investment value, which reflects the worth to a specific buyer, and from strategic value, which includes the worth of synergies.
Control matters too, since a control interest carries a different value than a minority stake in the same company, even on the same day.
How Do You Value a Privately Held Company?
Qualified valuators generally rely on three accepted approaches and apply one or more of them according to the industry, financial history, asset base, and purpose of the engagement. The AICPA Statement on Standards for Valuation Services (SSVS No. 1) identifies these approaches as the income approach, the market approach, and the asset-based approach.
Income Approach
This method converts expected future economic benefits into a present value. Two common techniques:
- Capitalization of earnings/cash flow: applies a single capitalization rate to a normalized, ongoing level of earnings
- Discounted cash flow (DCF): projects multiple years of cash flow and discounts them back to today, plus a terminal value
The reliability of a DCF depends heavily on whether projections rest on historical performance and realistic business risk instead of on optimism about growth next year.
Market Approach
Here, the valuator looks at what similar businesses actually sold for, using:
- Guideline public companies: comparable publicly traded firms, adjusted for size and risk differences
- Precedent transactions: actual sales of similar private businesses
Revenue, EBITDA, or other earnings metrics typically form the valuation base. The valuator then adjusts those figures for differences in size, growth rate, profitability, and risk between the subject company and the comparables.
Asset-Based Approach
This approach values tangible and intangible assets, less liabilities. It works particularly well for asset-heavy businesses, holding companies, or distressed operations, but it often understates the value of a profitable operating company because it does not fully capture going-concern earning power.
A simplified illustration uses hypothetical figures only. A valuator might capitalize the normalized EBITDA of $2 million for a company under the income approach, cross-check the result against a market multiple from comparable transactions, and reconcile it against net asset value if the company also holds significant real estate.
The valuator weighs these results according to the reliability of the data and the facts specific to the business, not a mechanical average.
One practical note: interest rates, financing conditions, and industry transaction data shift constantly, so a defensible valuation dates its market assumptions and does not treat them as fixed truths.
How Do You Calculate Equity Value for a Private Company?
Enterprise value represents the value of the operating business itself, before any consideration of how the owners finance it. Equity value equals what remains for the owners after balance-sheet adjustments. These two numbers differ, and confusion between them leads to bad expectations.
The general bridge from enterprise value to equity value looks like this:
- Start with enterprise value
- Add excess cash and other non-operating assets (where appropriate)
- Subtract interest-bearing debt and debt-like obligations
- Adjust for working capital or other transaction-specific items
As the Journal of Accountancy explains, a valuator subtracts debt net of excess cash from enterprise value to arrive at equity value.
Why the Details Matter
Practitioners do not treat cash, real estate, shareholder loans, leases, and contingent liabilities in one standardized way, and the treatment depends on the purpose and methodology of the engagement. A valuator must separate operating assets from non-operating ones, or the equity value will not reflect reality.
Ownership specifics also change the math. Voting rights, restrictions written into the ownership documents, and preferred versus common rights all affect the worth of a specific slice of equity, even when the business value of the company stays constant.
Discounts Aren't Automatic
Discounts for lack of control (DLOC) and lack of marketability (DLOM) may apply to certain interests, but each one depends on the specific facts.
In Mandelbaum v. Commissioner, the U.S. Tax Court applied a 30% marketability discount after it weighed several specific factors, as detailed in the Tax Court's Mandelbaum decision. The court did not treat that figure as a default rate. A valuator who copies a discount percentage from another case invites a challenge to the valuation.
Before accepting an equity value conclusion, ask:
- What value premise was used (going concern, liquidation)?
- What liabilities were deducted, and why?
- What specific ownership interest was valued (controlling, minority, voting, non-voting)?
- What valuation date applies?
- What assumptions or discounts were applied, and are they supported?
What Factors Can Increase or Reduce Private Company Value?
Two companies with identical revenue can carry very different values, and the factors below typically move value the most.
Financial performance quality:
- Recurring revenue and repeatable earnings generally support stronger value than one-time gains
- Owner-specific or discretionary expenses need to be normalized out of earnings
- Credible growth prospects, not just historical performance, factor into forward-looking methods
Operational and market position:
- Customer concentration (heavy reliance on one or two accounts raises risk)
- Supplier dependence that limits negotiating power or continuity
- IP strength, regulatory exposure, and barriers to entry that protect—or erode—pricing power
Key-person risk:
- A business that can't run without its founder is riskier than one with real management depth
- NACVA's Core Body of Knowledge flags key-person dependence, employment agreements, and non-competes as items that may need a distinct risk adjustment
Balance-sheet and financial quality:
- Debt load and working-capital needs
- Capital expenditure requirements
- Accounting quality and tax compliance history
- Reliability of management's forecasts
The same company can also look different to different audiences. A strategic buyer may price in synergy that a court would ignore, and a tax authority applies fair market value without regard to the plans of any one buyer.
A quick sensitivity example, with hypothetical figures, shows the effect: if the projected growth rate of a company drops from 8% to 4%, or its discount rate rises by even a couple of percentage points, the value conclusion can shift materially. A credible valuation report therefore shows sensitivity to key assumptions and does not rest on a single point estimate alone.
When Might a Private Company Need a Valuation?
Valuation needs generally fall into four buckets:
- Transaction: sale or acquisition analysis, exit planning, partner buyouts
- Tax and estate: gifting, estate administration, trust funding, tax return support
- Ownership: succession planning, buy-sell agreements, ESOP compliance
- Legal: judicial proceedings, shareholder disputes
Owners often miss that a valuation prepared for one purpose may not answer another. The valuation date, the applicable standard of value, and the required report format can all differ. A valuation built for a family gift under Form 709 disclosure rules follows different documentation expectations than one prepared for a buy-sell agreement trigger.
The point at which an owner orders a valuation also matters more than people assume. Owners who commission a valuation years before a planned sale get a roadmap, not just a number. A good valuation identifies specific value drivers and weaknesses that a buyer would flag, which gives the owner time to fix problems before they surface during due diligence.
How to Prepare for a Defensible Private Company Valuation
A defensible conclusion starts with organized information. Here's what a valuator typically needs:
- Financials: several years of statements and tax returns, interim financials, budgets, and forecasts
- Accounting detail: general ledger or trial balance, debt schedules, fixed-asset records
- Ownership documents: governing documents, cap tables, buy-sell agreements
- Business context: customer and supplier information, employee data, leases, litigation history, material contracts
The Typical Workflow
- Define the purpose and valuation date
- Gather financial and operational information
- Interview management about the business and its risks
- Analyze the industry and company-specific position
- Select appropriate methods and normalize financial results
- Assess risks, apply discounts if supported, and run sensitivity analysis
- Issue the appropriate report for the intended use
Practical prep tips that speed things up:
- Reconcile financial records before the engagement starts
- Document unusual or non-recurring items
- Separate personal expenses run through the business
- Clearly document customer concentration and recurring revenue
Projections need defensible assumptions, not optimism.

Frequently Asked Questions
How do you value a privately held company?
Valuators generally apply the income, market, and asset-based approaches and then reconcile the results. The right method depends on the company, the purpose and date of the valuation, and the information available.
How do you calculate equity value for a private company?
Equity value typically starts with enterprise value, adds appropriate cash or non-operating assets, and subtracts debt and debt-like obligations. Adjustments for the ownership interest may also apply, according to the specific stake that the valuator values.
How many times earnings is a business worth?
No universal multiple exists. The appropriate figure depends on industry, size, growth, profitability, risk, customer concentration, market conditions, and the definition of earnings for that specific business.
When should a business owner obtain a formal valuation?
Common triggers include a sale, succession, a partner buyout, a gift, an estate settlement, the funding of a trust, ESOP compliance, or a tax return. The owner should first define the intended purpose, because the purpose shapes everything else about the engagement.
Do private companies receive discounts in a valuation?
Discounts for lack of control or lack of marketability may apply to certain ownership interests, but each depends on the facts and the purpose of the valuation. A valuator should never copy a discount from a generic percentage or from another case.
What information does a valuator need from a private company?
A valuator typically requests financial statements, tax returns, forecasts, ownership and governing documents, debt schedules, contracts, customer and industry details, and explanations for any unusual financial items.
