Owners typically seek a valuation for one of several reasons: a potential sale, succession or exit planning, a partner buyout, estate or gift tax reporting, divorce, ESOP administration, or a judicial proceeding. Each of these situations comes with its own rules, standards, and expectations.
This article walks through the three valuation approaches, the difference between enterprise and equity value, the factors that push value up or down, and how to prepare so your valuation 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 is an independent estimate of what a business — or a specific ownership interest in it — is worth as of a particular date, prepared for a particular purpose. That last part matters more than most owners realize. A valuation built for a family gift won't necessarily answer the question a buyer or an ESOP trustee is asking.
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, with neither party compelled to act and both having reasonable knowledge of the relevant facts. That standard underlies most tax-driven valuations, but it isn't the only one.
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 (worth to a specific buyer) and from strategic value (worth including synergies).
Control matters too. A controlling interest is worth something different 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, applying one or more depending on the industry, financial history, asset base, and purpose of the engagement. The AICPA Statement on Standards for Valuation Services (SSVS No. 1) identifies these as the income, market, and asset-based approaches.
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 are grounded in historical performance and realistic business risk, not wishful thinking about next year's growth.
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. Those figures are then adjusted 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's particularly useful for asset-heavy businesses, holding companies, or distressed operations, but it often understates value for a profitable operating company, since it doesn't fully capture going-concern earning power.
A simplified illustration (hypothetical figures only): a company with $2 million in normalized EBITDA might be capitalized using the income approach, cross-checked against a market multiple from comparable transactions, and reconciled against net asset value if the company also holds significant real estate.
The valuator weighs these results based on data reliability and business-specific facts, not a mechanical average.
One practical note: interest rates, financing conditions, and industry transaction data shift constantly. A defensible valuation dates its market assumptions rather than treating 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 considering how it's financed. Equity value is what's left for the owners after balance-sheet adjustments. These two numbers are not the same, and confusing 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, debt net of excess cash is subtracted from enterprise value to arrive at equity value.
Why the Details Matter
The treatment of cash, real estate, shareholder loans, leases, and contingent liabilities isn't standardized. It depends on the engagement's purpose and methodology. Operating assets need to be separated from non-operating ones, or the resulting equity value won't reflect reality.
Ownership specifics also change the math. Voting rights, governing-document restrictions, and preferred versus common rights all affect what a specific slice of equity is worth, even when the underlying business value stays constant.
Discounts Aren't Automatic
Discounts for lack of control (DLOC) and lack of marketability (DLOM) may apply to certain interests, but they're fact-specific.
In Mandelbaum v. Commissioner, the U.S. Tax Court applied a 30% marketability discount after weighing several specific factors, as detailed in the Tax Court's Mandelbaum decision. That figure was not a default rate. Copying a discount percentage from another case is a fast way to get a valuation challenged.
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. Here's what typically moves the needle.
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 depending on who's asking. A strategic buyer may price in synergy a court would ignore; a taxing authority applies fair market value without regard to any one buyer's plans.
Quick sensitivity example (hypothetical): if a company's projected growth rate drops from 8% to 4%, or its discount rate rises by even a couple of percentage points, the resulting value conclusion can shift materially. A credible valuation report therefore shows sensitivity to key assumptions—not only a single point estimate.
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
Here's the part owners often miss: a valuation prepared for one purpose may not answer another. The valuation date, applicable standard of value, and 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.
Timing 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 a buyer would flag, giving the owner time to fix problems instead of discovering them 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, then reconcile the results. The right method depends on the company, valuation purpose, valuation date, and available information.
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. Ownership-interest adjustments may also apply depending on the specific stake being valued.
How many times earnings is a business worth?
There's no universal multiple. The appropriate figure depends on industry, size, growth, profitability, risk, customer concentration, market conditions, and how "earnings" is defined for that specific business.
When should a business owner obtain a formal valuation?
Common triggers include a sale, succession, partner buyout, gift, estate settlement, trust funding, ESOP compliance, or tax filing. Defining the intended purpose first 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 they're fact-specific and purpose-specific. They should never be copied from a generic percentage or another case.
What information does a valuator need from a private company?
Expect requests for financial statements, tax returns, forecasts, ownership and governing documents, debt schedules, contracts, customer and industry details, and explanations for any unusual financial items.
