Business valuation multiples vary significantly by industry, with Finance and Insurance commanding the highest SDE multiples at 3.4-5.1x, while Construction and Healthcare typically range 2.0-2.6x according to DealStats data from 2014-2023.

Wholesale Trade consistently commands above-average multiples at 2.8-3.7x, while Manufacturing maintains stability at 2.4-3.1x. Information sector businesses show high volatility ranging 2.0-3.7x.

Retail Trade ranges 2.2-2.9x and Professional Services ranges 2.2-2.7x. Transportation and Warehousing shows the widest range at 1.9-3.x, reflecting diverse business models within the sector.

Public company EBITDA multiples are significantly higher, ranging from 10x to 56x, creating substantial valuation arbitrage opportunities for roll-up strategies.

HVAC businesses typically trade at 1-2x earnings multiples for owner-operated companies with $1-2M revenue, but can achieve 7x+ multiples through strategic roll-ups and recurring revenue conversion.

A documented HVAC roll-up case shows progression from 2.5-3x multiple to 7x multiple while achieving 10x revenue growth through bundled services. The strategy involved acquiring complementary businesses like electrical, plumbing, pool cleaning, and landscaping.

Private equity firms actively target HVAC companies over $10M revenue, with one example showing $55M revenue generating $8.5M profit selling for $120M. Scale unlocks premium valuations in consolidating industries.

Seasonality challenges can be addressed through strategic acquisitions of businesses using the same crew in opposite seasons, creating year-round revenue streams.

Restaurant businesses require careful normalization to determine true valuation multiples, as reported earnings often understate actual owner economics due to family labor and personal expenses.

A documented specialty restaurant case with $2M annual revenue showed reported net income of only $64,000, but true Seller's Discretionary Earnings (SDE) of approximately $251,000 after proper adjustments.

Common restaurant SDE adjustments include normalizing owner compensation (removing excess family salaries), eliminating personal expenses coded as business costs, and adjusting rent to market rates.

Restaurant multiples typically fall within the Retail Trade range of 2.2-2.9x SDE, though specific multiples depend on concept, location, and operational efficiency.

Converting SDE to EBITDA requires subtracting owner benefits that would not continue under new ownership, providing the true economic basis for valuation multiples.

Owner benefits to subtract include: salary above market rate (if owner pays themselves $300K but replacement costs $100K, subtract $200K difference), personal vehicles on company books, and personal travel coded as business expenses.

Additional adjustments include removing family members on payroll who aren't essential to operations, country club memberships, and personal insurance through the company.

This conversion is critical because most industry EBITDA multiples assume professional management, while SDE reflects owner-operator benefits that inflate apparent profitability.

Healthcare and Social Assistance businesses (NAICS 62) typically trade at 2.0-2.6x SDE multiples according to DealStats data, placing them in the lower-middle range of industry valuations.

Medical practices require industry-specific multiple research rather than general healthcare ranges, as specialties, patient bases, and revenue models vary significantly within the sector.

The fragmented nature of healthcare creates roll-up opportunities, where individual practices trading at 2-4x SDE can be consolidated into portfolios commanding 7-9x multiples from private equity.

Scale becomes particularly important in healthcare, with larger medical service companies achieving premium valuations due to operational efficiencies and reduced regulatory compliance costs per unit.

Multiple free sources provide industry valuation data for negotiation support, starting with targeted Google searches for '[industry] multiples' or 'how much is a [business type] worth'.

Primary research sources include the Pepperdine Capital Markets Project, BizBuySell, FirstPage Sage, NYU Stern School of Business industry multiple tables, and Equidam industry reports.

For franchise businesses, contact the franchisor directly about typical deal pricing within their ecosystem, as established franchise systems often have comparable transaction data.

Consult multiple sources because each draws from different transaction cohorts, causing significant variation. Industry publications and M&A advisory firm reports provide additional validation.

The systematic formula begins by determining net asking price by subtracting any real estate value, since real estate is typically valued and sold separately from business operations.

Step two calculates the ask multiple by dividing net asking price by EBITDA (or converting SDE to EBITDA for owner-operated businesses by subtracting market-rate replacement salary).

Step three involves looking up public industry EBITDA multiples from sources like NYU Stern or Equidam, while step four divides the public multiple by four to approximate appropriate private company multiples.

This provides a reasonable valuation range within 15 minutes of desk research, establishing negotiation boundaries based on documented market data.

Published industry multiples typically reflect larger companies and must be adjusted downward for smaller businesses, with dramatic differences between size categories.

Smaller consulting businesses under $10M revenue trade at 0.75-1.25x earnings for small businesses and 0.25-3.5x for medium businesses, significantly below published industry averages.

Companies over $10M revenue command premium multiples due to scale advantages, operational efficiency, and reduced relative transaction costs for acquirers.

The size premium is particularly pronounced in consolidating industries where private equity actively acquires larger platforms, creating valuation arbitrage opportunities for strategic roll-ups.
