How to Value a Small Business — EBITDA Multiples Explained

Why EBITDA and Not Net Income

Net income is the wrong starting point for business valuation because it is heavily influenced by decisions that have nothing to do with the business's underlying economics. A seller who ran $200K in personal expenses through the business, paid himself $600K in salary against a market rate of $120K, and depreciated a fleet of trucks over 5 years is reporting dramatically different net income than the same business would show under new ownership.

EBITDA removes these distortions by adding back interest (financing choice, not operations), taxes (tax strategy, not operations), depreciation, and amortization. Then buyers apply additional adjustments — called add-backs — to normalize the remaining expenses to what a new owner would actually experience. The result is "adjusted EBITDA" — the number that gets multiplied.

For owner-operated businesses under $1M in earnings, buyers often use SDE (Seller's Discretionary Earnings) instead of EBITDA. SDE adds back the owner's total compensation on top of the EBITDA adjustments, representing the total economic benefit available to a full-time owner-operator. SDE multiples run lower than EBITDA multiples because SDE includes compensation that must be replaced.

How to Calculate Adjusted EBITDA

Start with the business's net income from its tax return. Add back: federal and state income taxes, interest expense, depreciation, and amortization. This is unadjusted EBITDA.

Then add back legitimate normalizing adjustments: (1) excess owner compensation — the difference between what the seller paid themselves and what a qualified manager would cost in the market; (2) personal expenses run through the business, documented with receipts; (3) one-time non-recurring expenses like legal settlements, facility moves, or equipment replacements that won't recur; and (4) rent above or below market rate if the seller also owns the real estate.

Buyers scrutinize every add-back. The standard of proof is documentation: payroll records, invoices, tax forms, bank statements. Sellers who present undocumented add-backs as given will face pushback during diligence — and often end up with a lower purchase price because the buyer can't underwrite what they can't verify. Have your CPA prepare a clean add-back schedule before going to market.

EBITDA Multiple Ranges by Industry

EBITDA multiples in the lower middle market ($1M–$5M revenue range) vary significantly by industry. Here are typical ranges for common acquisition targets.

• Home services (HVAC, plumbing, electrical, roofing): 3.5x–6.0x, driven by recurring maintenance revenue and licensing moats
• Healthcare practices (dental, veterinary, urgent care, physical therapy): 4.5x–8.0x, driven by licensed revenue and high switching costs
• Professional services (accounting, financial planning, insurance agencies): 4.0x–7.0x, driven by recurring client relationships and retention rates
• B2B services and IT managed services: 4.0x–7.0x, driven by contract length and revenue predictability
• Manufacturing and distribution: 3.5x–6.5x, driven by customer diversity and asset value
• Retail and restaurants: 2.0x–4.5x, driven by lease risk and competition intensity
• Self-storage and laundromats: 5.0x–9.0x, driven by low labor cost and semi-passive income

What Drives Premium vs. Discount Multiples

Within any industry range, individual deals land at the high or low end based on five primary factors.

Revenue quality and predictability is the largest driver. A business with 70% recurring contract revenue trades at 1–2x higher multiple than a comparable business that is entirely transactional. Customers under contract cannot leave tomorrow morning.

Management depth is the second. If the business can run without the seller for 90 days — because there is a real management team, documented processes, and no key-person dependencies — buyers price it significantly higher than a business where all operations flow through the founder.

Growth trajectory matters too. A business showing 15% year-over-year revenue growth with margin expansion commands a premium. A business with flat or declining revenue requires buyers to underwrite a turnaround, which compresses multiples.

Customer concentration, EBITDA margin versus industry peers, and clean compliance/legal history round out the top five. See our industry-specific valuation guides for accounting firms, septic services, and urgent care clinics to understand how these factors play out in practice.

Comparable Transactions Analysis

EBITDA multiples are not invented — they are derived from actual market transactions. Sell-side advisors and business brokers reference recent deals in the same industry and size range to benchmark asking price. As a buyer, you should do the same.

Sources for transaction comparables include: BizBuySell closed transaction data, IBBA (International Business Brokers Association) market reports, BizBuySell transaction reports, and private database subscriptions like PitchBook or PrivCo for larger deals. For industries with active PE rollup activity — home services, healthcare, landscaping — PE firms often publish acquisition criteria that imply their purchase price multiples.

The goal is not to find one transaction that justifies your price — it is to establish a credible range from multiple data points. A CIM (Confidential Information Memorandum) from a quality sell-side advisor will include a comp set. If you are buying without a sell-side advisor involved, you will need to build your own.

Building Your Valuation Case

Whether you are a buyer defending your offer or a seller justifying an ask, the structure of a valuation case is the same: start with adjusted EBITDA, apply a multiple supported by comparable transactions, and adjust up or down for the specific business's quality factors.

For buyers, present a range: your view of adjusted EBITDA (with conservative, base, and optimistic scenarios), a multiple range based on comps, and a resulting price range. Anchor your initial offer at the low end of the range with a clear explanation of what would need to be true to support the higher end — and invite the seller to provide evidence supporting the upside.

For sellers, the valuation case starts 12–24 months before going to market: cleaning up add-backs, reducing customer concentration, and increasing the management team's operational independence. A business that can demonstrate three years of clean, growing EBITDA with documented recurring revenue and a capable management team will consistently command the top of its industry multiple range.
