How to Value Private Companies Ask a public company what it's worth, and the stock ticker answers instantly. Ask a private business owner the same question, and things get complicated fast.

There's no ticker for a $40 million distribution company in Massachusetts. No daily quote for a family-owned specialty food producer. Owners eventually ask "what is my company worth" anyway, usually because a sale is on the horizon, they're raising capital, planning their estate, or just curious where they stand financially.

The honest answer is that a private company is not priced against a public comparable at all. It is priced against the return the buyer has to earn, and the debt the business can carry is part of that calculation. This guide walks through the three core valuation approaches, the arithmetic a buyer runs behind them, the factors that move your multiple, the discounts unique to private businesses, and how to prepare.

Key Takeaways

  • Credible private company valuations blend income, market, and asset-based approaches rather than relying on one method
  • Private businesses face discounts (marketability, control, key-person) that public companies never encounter
  • Customer concentration, founder dependency, and financial quality shift multiples as much as revenue growth does
  • Institutional buyers target returns of roughly 20% to 30% a year, and they build the price they can pay backward from that hurdle

What Is Private Company Valuation?

Private company valuation is an estimate of fair market value built from financials, market comparables, and future earning potential. Unlike public stocks, there's no live market price to check, so appraisers have to build one from the ground up.

The AICPA's valuation standards apply this framework to transactions, financing, taxation, mergers, and litigation. The core challenge is always the same: limited data, illiquid shares, and no continuously updated price feed to sanity-check your number.

Owners typically request a valuation for one of these reasons:

  • Preparing to sell the business
  • Tax or estate planning
  • Buying out a partner or co-owner
  • Litigation or shareholder disputes
  • Understanding net worth ahead of a major decision

IRS Revenue Ruling 59-60 still sets the baseline: when stock is closely held or infrequently traded, "some other measure of value must be used." That standard continues to guide how appraisers build private company valuations today.

The Three Core Approaches to Valuing a Private Company

Income Approach: Valuing Future Cash Flow

The Discounted Cash Flow (DCF) method projects your company's future free cash flow and discounts it back to today's dollars using a discount rate that reflects risk.

Private companies often warrant a higher discount rate than public peers. That is not a blanket markup. It reflects real risk factors such as illiquidity, a thinner management bench, and customer concentration. The rate should match the risk of the specific cash flow stream being valued.

For businesses with steady, predictable earnings, Capitalization of Earnings is a simpler alternative:

  • Start with a normalized earnings figure
  • Divide by a capitalization rate that reflects risk and growth
  • Use it when recent results reasonably represent the near term, without a full multi-year forecast

Market Approach: Comparing to Similar Companies

Two methods dominate here:

  1. Comparable Company Analysis: applies multiples (EV/EBITDA, EV/Revenue) from similar businesses to your company's financials
  2. Precedent Transaction Analysis: looks at actual M&A deals in your sector to infer what buyers have recently paid

The catch: finding truly comparable private transactions is harder than pulling public comps. Deal terms and financials from private M&A are often incomplete or stale. For middle-market companies, current sector-specific deal data matters more than generic public multiples alone.

Asset-Based Approach: Valuing the Balance Sheet

This approach calculates net asset value: total assets minus liabilities. It fits asset-heavy businesses or holding companies, such as real estate portfolios or investment holding structures.

For a profitable operating business, this method alone usually falls short. It ignores goodwill, customer relationships, and future earning power. Appraisal standards generally treat it as a floor or cross-check, not the primary answer, unless buyers and sellers in that industry customarily value businesses that way.

How analysts blend these three approaches: There is no fixed formula. Weighting follows the quality of the evidence:

  • Income approach when forecasts are credible and earnings power drives value
  • Market approach when solid comparable companies or transactions exist
  • Asset approach when non-operating assets or holding-company economics dominate

The goal is a defensible range, not a mechanically averaged number.

The Number a Buyer Backs Into

The three approaches above are how an appraiser builds a value. They are not how an acquirer arrives at a price. An institutional buyer starts from the return it has promised its own investors and works backward to the most it can pay and still earn it.

Institutional investors typically target internal rates of return between 20% and 30% a year. Everything else follows from that. The buyer models what your EBITDA becomes over a five-year hold, how much of the purchase it can fund with debt, and how much debt the business repays out of its own cash flow. Whatever price satisfies the return at the end is the price you are offered.

Capital structure is therefore part of your valuation, not a detail settled afterward. Senior bank lenders in middle-market transactions generally lend two to three times EBITDA. On $8 million of EBITDA at 2.5 times, that is $20 million of senior debt. A capital structure the client's own material describes puts a $57.6 million enterprise value together as $20.0 million of senior debt and $37.6 million of equity, with the remaining layers drawn from subordinated or mezzanine debt, investor equity, and seller rollover.

This is why a public comparable rarely transfers. A public multiple prices a liquid minority share in a company with audited statements and a full management team. Your buyer is pricing a controlling stake it has to finance, hold, improve and sell inside five years. Different question, different number.

Key Factors That Influence Your Company's Valuation

Revenue and EBITDA trends set the baseline, but buyers pay premiums or apply discounts based on what sits underneath those numbers.

Revenue quality matters more than revenue size. Buyers pay up for recurring, diversified, and predictable revenue streams over lumpy, project-based income.

Customer concentration drags on value. Academic research consistently links heavy reliance on a few large customers to higher cost of equity for the supplier. Buyers price in the risk that losing one account could sink the business.

Exit Boston has seen this firsthand: one label manufacturer client converted short-term purchase orders from large customers into extended supply agreements to improve revenue visibility ahead of a sale.

Founder dependency is often the biggest hidden discount. A business that can't function without its owner isn't really transferable.

Exit Boston worked with a regional label manufacturer that initially couldn't clear 4.8x EBITDA because institutional buyers saw excessive founder reliance and no management incentive structure. After six months building an independent leadership team, a Management Incentive Program, and a founder transition plan, the company sold at 6.4x EBITDA. The multiple later expanded to 8.2x as EBITDA grew from $3.4 million to $9.0 million, but that took four and a half years and three bolt-on acquisitions under the new private equity owner, not the six months of preparation.

Other factors buyers weigh:

  • Industry positioning: fast-growing sectors and defensible niches command higher multiples
  • Management depth: a capable team beyond the founder signals continuity to buyers
  • Financial cleanliness: GAAP-consistent statements build confidence; commingled personal expenses raise red flags and slow deals

Valuation Discounts Unique to Private Businesses

Private companies carry discounts public stocks never face, because there's no easy exit for the owner. Discount for Lack of Marketability (DLOM). Private shares can't be sold in a day like public stock. Investors demand a higher return to compensate, which lowers present value. A 2025 Pepperdine report found controlling-interest DLOM medians ranging from 15.0% for $100K-revenue companies down to 5.3% for $250M-revenue companies. Smaller businesses generally see steeper marketability discounts. Minority interest discount (lack of control). If you don't hold full control (say you own 30% of the company), your stake is worth less proportionally than a controlling interest, since you can't unilaterally decide to sell, merge, or liquidate. Key person discount. Businesses overly dependent on the founder or a small handful of employees carry real transition risk. Reducing that dependency before a sale is one of the most direct ways to raise your valuation, as the label manufacturer example above shows. These figures are benchmarks, not automatic deductions. Every valuation needs to justify its specific discount based on the actual company, not a published average.

Preparing Your Business for a Premium Valuation

Valuing a business for a future exit is different from a routine appraisal. Institutional buyers such as private equity firms, strategic acquirers, and family offices pay premiums for companies that already resemble institutional-quality assets. Exit Boston evaluates readiness through its Seven Pillars:

  1. Owner Independence: what breaks if you step away?
  2. Management Depth: who is actually running this business post-close?
  3. Financial Clarity: can a buyer trust the numbers and model the future?
  4. Margin Quality: are the margins sustainable, or are they risk?
  5. Recurring Revenue: how much of next year is already visible?
  6. Operating Infrastructure: will the business scale, or break under growth?
  7. Growth Pathways: where does new capital go, and what does it return? Owner independence is the threshold question, and the one that moves the multiple most. Documented systems turn day-to-day effort into transferable enterprise value. Competitive tension among buyers also drives premium outcomes. Exit Boston's research team maps the buyer landscape and identifies which buyer type is most likely to pay a premium for a specific business. The firm then positions the opportunity around that buyer's investment-committee criteria before going to market. Across documented transactions, this approach has driven outcomes averaging 20%+ above initial expected valuation ranges. One precision-manufacturing client saw valuation grow from an initial $61 million estimate to a $165 million platform sale. Exit Boston works with founders of companies generating $10 million to $100 million in revenue and $2 million to $10 million in EBITDA to assess true market value and position the business for premium acquisition offers before it reaches the market.

Frequently Asked Questions

How do you value a private business?

Valuers combine the income approach (DCF or capitalization of earnings), the market approach (comparable companies or precedent transactions), and the asset-based approach to build a defensible value range. No single method stands alone.

What is private market valuation?

It's the process of estimating what a company is worth when its shares aren't publicly traded. Because there's no live stock price, appraisers rely on financial analysis and comparable deal data instead.

How much does a business valuation typically cost?

Costs vary by business complexity and purpose, often ranging from a few thousand dollars to well over $10,000. M&A advisors frequently provide informal valuation guidance as part of a broader exit planning engagement.

What's the difference between a valuation for tax purposes and one for selling my business?

Tax and estate valuations follow strict IRS fair market value standards. Sale valuations reflect what a specific buyer will actually pay, which often includes synergies a tax appraisal wouldn't count.

Can I increase my company's valuation before selling?

Yes. Reducing owner dependency, diversifying your customer base, and cleaning up financials in the 1-3 years before a sale can meaningfully raise your multiple. Owner independence is the pillar that moves it most.

How long does a business valuation take?

Most valuations take a few weeks, depending on data quality and how deep the analysis needs to go. Messy financial records extend the timeline significantly.
