Valuation Approaches

Overview of Main Approaches

There are three primary approaches to business valuation:

  1. Income Approach: Values based on expected future benefits
  2. Market Approach: Values based on comparable company data
  3. Asset Approach: Values based on net asset value

Each approach has multiple methods within it, and professional valuations often use multiple methods to triangulate a value.

Income Approach

The income approach values a business based on the present value of expected future cash flows or earnings.

1. Discounted Cash Flow (DCF) Method

DCF is the most comprehensive income approach method, calculating the present value of projected future cash flows.

Steps in DCF Analysis

Step 1: Project Future Cash Flows

Project free cash flow for 5-10 years:

Free Cash Flow = EBIT ร— (1 - Tax Rate) + Depreciation & Amortization 
               - Capital Expenditures - Change in Working Capital

Step 2: Determine Terminal Value

Calculate value beyond the projection period:

  • Perpetuity Growth Method: TV = Final FCF ร— (1 + g) / (WACC - g)
  • Exit Multiple Method: TV = Final Year EBITDA ร— Industry Multiple

Step 3: Calculate Discount Rate

Determine weighted average cost of capital (WACC):

WACC = (E/V) ร— Re + (D/V) ร— Rd ร— (1 - Tc)

Where:
E = Equity value
D = Debt value
V = Total value (E + D)
Re = Cost of equity
Rd = Cost of debt
Tc = Corporate tax rate

Step 4: Calculate Present Value

Discount all cash flows to present value:

Enterprise Value = ฮฃ (FCFt / (1 + WACC)^t) + (Terminal Value / (1 + WACC)^n)

Example Calculation

Assumptions:

  • Projected FCF: $500,000 (Year 1), growing 10% annually
  • Terminal growth rate: 3%
  • WACC: 12%
  • Projection period: 5 years

Year 1-5 Cash Flows:

  • Year 1: $500,000
  • Year 2: $550,000
  • Year 3: $605,000
  • Year 4: $665,500
  • Year 5: $732,050

Terminal Value: $732,050 ร— 1.03 / (0.12 - 0.03) = $8,384,907

Present Value Calculation:

  • PV of cash flows: $2,125,000 (sum of discounted years 1-5)
  • PV of terminal value: $4,732,000
  • Enterprise Value: $6,857,000

2. Capitalization of Earnings Method

Simpler than DCF, this method capitalizes current earnings at an expected rate of return.

Formula

Business Value = Annual Earnings / Capitalization Rate

Example

  • Normalized Earnings: $300,000
  • Capitalization Rate: 15%
  • Business Value: $300,000 / 0.15 = $2,000,000

When to Use

  • Stable, predictable earnings
  • Smaller businesses
  • When DCF projections are uncertain

3. Multiple of Discretionary Earnings

Common for small businesses, this method multiples seller’s discretionary earnings (SDE).

What is SDE?

SDE = Net Profit + Owner's Compensation + Interest + Taxes + Depreciation 
    + Non-recurring Expenses

This adds back any expenses that would not exist under new ownership.

Typical Multiples by Industry

Industry SDE Multiple Range
Restaurants 2.0 - 3.0
Retail 2.0 - 3.5
Service 1.5 - 2.5
Manufacturing 3.0 - 4.0
Technology 3.0 - 5.0

Market Approach

The market approach values a business based on what similar companies have sold for or their trading multiples.

1. Comparable Company Analysis (Trading Multiples)

Uses multiples from publicly traded companies to value private businesses.

Common Multiples

Multiple Formula Interpretation
EV/Revenue Enterprise Value / Revenue Revenue multiple
EV/EBITDA Enterprise Value / EBITDA Operating profitability
P/E Price / Earnings Earnings multiple
P/S Price / Sales Sales multiple
P/B Price / Book Value Asset multiple

Process

  1. Select Comparable Companies: Find similar public companies
  2. Calculate Multiples: Compute multiples for each comp
  3. Determine Median Multiple: Use median to reduce outliers
  4. Apply to Subject Company: Multiply by subject’s metrics
  5. Adjust for Differences: Control for size, growth, risk

Example

Comparable Companies:

  • Company A: EV/EBITDA = 8.5x
  • Company B: EV/EBITDA = 7.2x
  • Company C: EV/EBITDA = 9.1x
  • Median: 8.5x

Subject Company:

  • EBITDA: $1,000,000
  • Implied Value: $1,000,000 ร— 8.5 = $8,500,000

2. Precedent Transaction Analysis

Uses multiples from actual sales of similar companies.

Process

  1. Find Comparable Transactions: Identify recent sales
  2. Calculate Transaction Multiples: Determine multiples paid
  3. Adjust for Timing: Consider economic changes
  4. Apply to Subject Company: Use median multiple
  5. Control Premium: Add control premium if applicable

Control Premium

A buyer typically pays more for control:

  • Typical control premium: 20-40%
  • Based on synergies expected
  • Reflects value of control

3. Comparable Acquisition Method

Similar to precedent transactions but may include private deals.

Asset Approach

The asset approach values a business based on the fair market value of its assets minus its liabilities.

1. Adjusted Net Asset Value Method

Starts with balance sheet and adjusts assets/liabilities to fair value.

Formula

Business Value = (Adjusted Assets) - (Adjusted Liabilities)

Common Adjustments

Asset Increases:

  • Real estate to market value
  • Accounts receivable minus bad debt reserve
  • Inventory to net realizable value
  • Intangible assets (patents, goodwill)

Liability Adjustments:

  • Unrecorded liabilities
  • Deferred tax liabilities
  • Warranty reserves

2. Liquidation Value

Value if the business were forced to liquidate:

  • Typically lower than going concern value
  • Assets sold at discount (20-50%+)
  • Costs of liquidation considered
  • Used in distress situations

Special Considerations

Value Drivers and Adjustments

Positive Factors:

  • Strong management team
  • Recurring revenue
  • High growth rate
  • Proprietary products/technology
  • Strong brand
  • Diversified customer base

Negative Factors:

  • Customer concentration
  • Key person dependency
  • Outdated technology
  • Regulatory issues
  • High debt levels

Minority Discount

For less than 50% ownership:

  • Typical discount: 20-35%
  • Reflects lack of control
  • Depends on shares outstanding
  • Consider marketability

Lack of Marketability Discount

For private company shares:

  • Typical discount: 20-50%
  • No public market for shares
  • Restricted stock studies
  • Combined with minority discount

Valuation for Different Purposes

Purpose Preferred Methods Key Focus
M&A Transaction DCF, Precedent Transactions Strategic value
Investor Pitch Comparable Companies, DCF Growth potential
Estate Planning Asset Approach, DCF Defensible value
Divorce Multiple Methods Court-acceptable
Bank Financing Asset Approach, Multiple of Earnings Conservative value
Exit Planning Multiple Methods Optimizing value

Valuation Adjustments and Premiums/Discounts

Control Premium

When acquiring a controlling interest (over 50%), buyers typically pay a premium above the minority share price:

Minority Share Price:     $50/share
Control Premium (30%):    $15/share
Control Price:            $65/share

Why control commands a premium:

  • Ability to set strategy and direction
  • Control over dividends and distributions
  • Ability to sell or merge the company
  • Access to synergies

Typical control premiums: 20โ€“40% above minority value (varies by industry and deal)

Minority Interest Discount

When valuing a minority stake (under 50%), apply a discount for lack of control:

Pro-rata value of 30% stake:    $3,000,000
Minority discount (25%):          ($750,000)
Minority interest value:         $2,250,000

Discount for Lack of Marketability (DLOM)

Private company shares are less liquid than public company shares โ€” no ready market exists:

Marketable minority value:      $2,250,000
DLOM (30%):                      ($675,000)
Non-marketable minority value:  $1,575,000

DLOM range: 20โ€“50% depending on:

  • Company size (larger = smaller discount)
  • Profitability and growth
  • Dividend history
  • Likelihood of IPO or sale

Combined Discounts

For a minority, non-marketable interest:

Control value:                  $10,000,000
Minority discount (25%):         ($2,500,000)
Marketable minority value:        $7,500,000
DLOM (30%):                      ($2,250,000)
Non-marketable minority value:    $5,250,000

The combined discount is 47.5% from control value โ€” significant for estate planning and shareholder disputes.

Industry-Specific Valuation Approaches

SaaS and Subscription Businesses

SaaS companies are typically valued on revenue multiples rather than earnings:

Key metrics:

  • ARR (Annual Recurring Revenue)
  • MRR (Monthly Recurring Revenue)
  • Net Revenue Retention (NRR)
  • Customer Acquisition Cost (CAC)
  • Lifetime Value (LTV)

Typical multiples (2026):

High-growth SaaS (>50% growth, >80% NRR): 8โ€“15ร— ARR
Mid-growth SaaS (20โ€“50% growth):           4โ€“8ร— ARR
Slow-growth SaaS (<20% growth):            2โ€“4ร— ARR

Rule of 40: Growth rate + profit margin should exceed 40%

  • 50% growth + -10% margin = 40 (meets threshold)
  • 20% growth + 25% margin = 45 (exceeds threshold)

Professional Services Firms

Valued on revenue multiples or EBITDA:

  • Accounting firms: 0.5โ€“1.5ร— revenue
  • Law firms: 0.3โ€“0.8ร— revenue
  • Consulting firms: 0.5โ€“1.2ร— revenue
  • Key person risk is a major discount factor

Manufacturing Companies

Typically valued on EBITDA multiples:

  • Commodity manufacturing: 4โ€“6ร— EBITDA
  • Specialty manufacturing: 6โ€“10ร— EBITDA
  • Defense/aerospace: 8โ€“12ร— EBITDA
  • Asset-heavy businesses may use asset approach as floor

Real Estate

Valued using:

  • Cap rate: NOI / Cap Rate = Value
  • Comparable sales: Price per square foot
  • Replacement cost: Cost to rebuild
Net Operating Income (NOI):    $500,000
Market Cap Rate:                    6%
Property Value:              $8,333,333

Retail Businesses

  • Small retail: 2โ€“3ร— SDE (seller’s discretionary earnings)
  • Franchise locations: 2.5โ€“4ร— EBITDA
  • E-commerce: 2โ€“5ร— EBITDA (higher for strong brands)
  • Key factors: Location, lease terms, customer concentration

Valuation in M&A Transactions

The Acquisition Process

Phase 1: Strategic rationale

  • Why acquire this company?
  • What synergies are expected?
  • How does it fit the strategy?

Phase 2: Preliminary valuation

  • Comparable company analysis
  • Preliminary DCF
  • Determine bid range

Phase 3: Due diligence

  • Financial due diligence (verify the numbers)
  • Legal due diligence (contracts, litigation, IP)
  • Operational due diligence (customers, employees, systems)
  • Adjust valuation based on findings

Phase 4: Final valuation and negotiation

  • Incorporate due diligence findings
  • Negotiate price and terms
  • Structure the deal (asset vs. stock purchase)

Synergy Valuation

Acquirers often pay above standalone value because of expected synergies:

Standalone value of target:     $50,000,000
Revenue synergies (PV):          $8,000,000
Cost synergies (PV):             $5,000,000
Total synergy value:            $13,000,000
Maximum price to pay:           $63,000,000

Types of synergies:

  • Revenue synergies: Cross-selling, new markets, pricing power
  • Cost synergies: Eliminating duplicate functions, procurement savings
  • Financial synergies: Lower cost of capital, tax benefits

Purchase Price Allocation (PPA)

After an acquisition, the purchase price must be allocated to acquired assets and liabilities:

Purchase Price:                 $50,000,000
Fair Value of Net Assets:       $30,000,000
Goodwill:                       $20,000,000

Allocation:
  Tangible assets (fair value):  $25,000,000
  Customer relationships:         $8,000,000
  Technology/IP:                  $5,000,000
  Trade name:                     $2,000,000
  Liabilities assumed:          ($10,000,000)
  Net identifiable assets:       $30,000,000
  Goodwill (residual):           $20,000,000

Identified intangibles are amortized; goodwill is tested annually for impairment.

Valuation for Specific Purposes

Estate and Gift Tax Valuation

IRS requires “fair market value” โ€” the price a willing buyer would pay a willing seller, both having reasonable knowledge of the facts, neither under compulsion.

Key considerations:

  • Minority and marketability discounts are generally allowed
  • IRS may challenge aggressive discounts
  • Qualified appraisal required for gifts over $10,000
  • Qualified appraiser must meet IRS standards

Divorce Proceedings

Business valuation in divorce is often contentious:

  • Both spouses may hire competing appraisers
  • Courts must resolve conflicting valuations
  • Personal goodwill (attached to owner) vs. enterprise goodwill (transferable) is a key issue
  • Some states exclude personal goodwill from marital estate

Employee Stock Ownership Plans (ESOPs)

ESOPs require annual independent appraisal:

  • Must reflect fair market value
  • Trustee has fiduciary duty to employees
  • DOL scrutinizes ESOP valuations closely
  • Typically uses income and market approaches

409A Valuations (Startup Stock Options)

Startups granting stock options must establish fair market value of common stock:

  • Required by IRS Section 409A
  • Typically done by independent appraiser
  • Common stock valued at discount to preferred stock
  • Updated when material events occur (funding rounds, acquisitions)

Conclusion

Business valuation is both an art and a science. While multiple methods exist, the key is selecting the appropriate method(s) for your specific situation and understanding the assumptions underlying each approach.

Key takeaways:

  • Use multiple methods and triangulate to a value range
  • Income approach (DCF) is most theoretically sound for going concerns
  • Market approach provides real-world benchmarks
  • Asset approach is the floor for asset-heavy businesses
  • Premiums and discounts significantly affect minority interest values
  • Industry-specific metrics matter (ARR for SaaS, NOI for real estate)
  • Purpose of valuation affects methodology (M&A vs. estate vs. divorce)

For important valuations, engage a credentialed professional (CVA, ABV, ASA) who can provide an objective, defensible estimate of your company’s worth.
