Valuing a business isn’t an exact science, but understanding the math and methodologies that acquirers use can save you hundreds of thousands of dollars when you decide to sell. For most small-to-midsize businesses in the United States, valuation comes down to one core metric: EBITDA, multiplied by a factor determined by your industry, growth, and operations.
The Core Valuation Equation: Earnings x Multiple
At its simplest, the value of an operating business is calculated by taking its recurring earnings and multiplying them by a number (the "multiple"). However, the definitions of both "earnings" and "multiple" vary depending on the size and nature of your business.
- Seller's Discretionary Earnings (SDE): Typically used for owner-operated businesses with revenues under $2 million. SDE calculates the total financial benefit available to a single owner-operator, adding back owner salary, personal vehicles, health insurance, and other discretionary expenses.
- EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization): Used for larger, management-led businesses (generally over $1 million in net earnings). EBITDA represents the company's operating profitability under a neutral capital structure and without owner-specific perks.
Understanding SDE vs. EBITDA Multiples by Industry
Multiples represent the buyer's risk and the rate of return they expect. A lower multiple implies higher risk, while a higher multiple represents stability and growth. In the lower middle-market, most businesses sell for multiples between 2.0x and 6.0x.
- Service & Contracting (HVAC, Plumbing, Electrical): Typically command 2.5x to 4.5x SDE/EBITDA. Highly recurring service agreements and commercial accounts push this to the higher end.
- Manufacturing & Logistics: Typically command 3.5x to 5.5x EBITDA. Heavy asset ownership (machinery, real estate) and proprietary production processes attract higher multiples.
- Software & B2B Tech: Can command 4.0x to 7.0x+ EBITDA due to high gross margins and high recurring revenue (ARR/MRR) stability.

Adjustments and Add-Backs: Finding Your True EBITDA
Most business owners run their companies to minimize tax liabilities, which means their tax returns show artificially low net income. Before selling, we perform a process called "financial normalization" or calculating "Adjusted EBITDA." This involves adding back non-recurring, personal, or non-operational expenses.
Common legitimate add-backs include one-time lawsuit settlements, the excess salary paid to the owner above market rate for a CEO, personal club memberships, and discontinued product line startup costs. However, keeping these add-backs defensible with clean CPA-compiled records is crucial; aggressive or fabricated add-backs will quickly kill a buyer's trust during due diligence.
Key Value Drivers That Expand Your Multiple
Two businesses with the exact same EBITDA can sell for wildly different multiples. If you want to push your business valuation from a 3.0x multiple to a 4.5x or 5.0x multiple, you must focus on the following value drivers:
- Low Customer Concentration: No single customer should represent more than 10-15% of your total revenue. High customer concentration is a primary driver of deal failure.
- Operational Systems: Standardized Operating Procedures (SOPs) that allow the business to run smoothly without the owner's active daily involvement.
- Management Depth: A capable second-in-command who is staying with the business post-acquisition.
