Quick answer: EBITDA valuation takes your business's earnings before interest, taxes, depreciation, and amortization, then multiplies by an industry-specific number (the "multiple") to arrive at an estimated enterprise value. For most small businesses, EBITDA multiples range from 2–6x. A business with $500,000 EBITDA and a 4x multiple would be valued at $2,000,000 — before adjusting for debt and working capital.
Calculating EBITDA for a Small Business
EBITDA starts with net income and adds back interest expense, income taxes, depreciation, and amortization. For owner-operated businesses, buyers also add back owner's compensation above market rate (the excess you pay yourself above what a hired manager would cost) and any personal expenses run through the business — this adjusted figure is called "Seller's Discretionary Earnings" (SDE) for businesses under $1M EBITDA. Example: $300,000 net income + $50,000 owner excess salary + $30,000 personal expenses + $40,000 depreciation = $420,000 adjusted EBITDA. At a 3.5x multiple, that's $1.47M enterprise value. Subtract business debt, add excess cash = equity value.
What Drives the Multiple Higher or Lower
Industry, size, and quality all affect the multiple. Factors that increase a multiple: recurring revenue (subscriptions, contracts), low customer concentration (no single client is more than 10–15% of revenue), strong management team that can operate without the owner, 3+ years of consistent growth, proprietary products or defensible market position, and clean financial records. Factors that compress the multiple: owner-dependent operations, customer concentration risk, declining revenue, industry disruption, or a single location with no scalability. A business transitioning from owner-dependent to systems-driven can meaningfully increase its multiple before sale.
Why EBITDA Matters Before You're Ready to Sell
Many business owners think valuation only matters when they're ready to exit. In reality, understanding your EBITDA multiple now lets you make decisions that increase value over time — reducing owner dependence, improving margins, diversifying your customer base. EBITDA also drives buy-sell agreement pricing; your agreement should specify how EBITDA is calculated and how often the valuation is updated. Outdated fixed-price buy-sells often result in estates being dramatically underpaid. Have a business valuation professional review your number every 2–3 years, and consult your CPA and financial advisor on how to systematically increase it.
