Business value is not a number — it is a range, produced by applying recognized methods to verified financial data. The asking price on a business-for-sale listing is the seller's opinion of value. The offer a buyer makes is theirs. The final purchase price is where those opinions converge after due diligence confirms — or adjusts — the underlying numbers. Understanding how to value a business means understanding the five methods serious buyers use, which method applies in which situation, and what factors move the multiple up or down once the method is selected. This is the hub guide for business valuation on DealFlow OS — it covers each method, when to use it, and how to normalize your earnings before applying any multiple.
The Foundation: Normalize Your Earnings First
No valuation method produces a reliable result until the earnings it is applied to are normalized. Normalization removes the distortions that characterize owner-operated business financials — expenses that reflect the owner's personal decisions rather than the ongoing cost structure of the business — so that the earnings figure represents what a new owner would actually earn.
The two earnings metrics used in small and mid-market business valuation:
SDE (Seller's Discretionary Earnings) is the pre-tax, pre-debt earnings of the business before the owner's total compensation — salary, benefits, perks, and personal expenses run through the business. It represents the total economic benefit available to one full-time owner-operator. SDE is the appropriate metric for businesses under approximately $2M in revenue where the owner is actively involved in operations.
EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is used for larger businesses where the owner is paid a market-rate salary (which is already included in expenses) and the business has a management layer that allows it to operate without the owner's daily presence. EBITDA is the standard for mid-market transactions and PE acquisitions.
Common add-backs in the normalization process:
| Add-Back | What It Is | How to Document |
|---|---|---|
| Owner salary above market rate | Compensation above what a hired manager would earn | Compare to industry manager comp data |
| Owner's personal expenses | Health insurance, vehicle, cell phone, travel run through business | Receipts and bank statements |
| One-time expenses | Non-recurring costs in the period being presented | Invoices and explanation of non-recurrence |
| Owner's family members on payroll | Compensation for non-working family members | Payroll records |
| Depreciation and amortization | Non-cash expenses that don't reflect economic cost | Income statement line items |
| Rent above/below market | If owner owns the real estate and charges unusual rent | Market rent comparison |
Every add-back must be documented with evidence. Buyers and SBA lenders will verify each one. Undocumented add-backs are discounted or excluded entirely.

Run your estimate →Method 1: SDE Multiple (Most Common for Small Businesses)
The SDE multiple is the most widely used valuation method for small businesses — typically those with enterprise values under $2M. It works by applying a market-derived multiple to normalized SDE.
Formula: Business Value = Normalized SDE × Industry Multiple
If a business has normalized SDE of $250,000 and comparable businesses in that industry sell for 2.5x SDE, the implied value is $625,000.
SDE multiples in the small business market typically range from 1.5x to 4.0x, with the median around 2.0x–2.5x for most main-street businesses. The multiple varies significantly by: - Business quality: Clean books, documented processes, and staff depth move the multiple up. Owner dependency, concentrated customers, and disorganized financials move it down. - Industry: Some industries command higher multiples (recurring revenue businesses, essential services, licensed specialties) than others (restaurants, retail, seasonal businesses). - Earnings size: Larger SDE commands higher multiples. A business with $150K SDE might attract a 2x multiple; the same business with $400K SDE in the same industry might attract a 2.8x multiple, because larger cash flows are more attractive to a wider buyer pool. - Growth trajectory: Growing businesses command premium multiples; declining businesses face significant discounts.
SDE multiples are transaction-derived from databases of completed sales — BizBuySell, Pratt's Stats, IBA Market Data. They reflect what actual buyers paid for actual businesses, which is why they are the most market-grounded method for small business valuation.
Method 2: EBITDA Multiple (Mid-Market Standard)
EBITDA multiples are the standard valuation currency for mid-market transactions — businesses with $500K or more in EBITDA — where PE buyers, strategic acquirers, and institutional lenders are active participants.
Formula: Enterprise Value = Normalized EBITDA × Industry Multiple
Unlike SDE, which adds back the owner's full compensation, EBITDA assumes the owner is paid a market-rate salary that remains in the expenses. This makes EBITDA appropriate for businesses with professional management structures — where a new owner does not need to personally run the day-to-day operations.
EBITDA multiples in the lower-middle market (businesses with $500K–$5M EBITDA) typically range from 3x to 8x depending on industry, growth, and buyer type. Industries with recurring revenue, high barriers to entry, or consolidation activity command higher multiples. For industry-specific EBITDA multiple data, the DealFlow OS valuation multiples library covers ranges and buyer criteria by industry.
The critical distinction between EBITDA and SDE: - SDE includes the owner's full economic benefit (salary + perks) in the numerator - EBITDA assumes the owner is paid at market rate; that salary stays in expenses
Applying a mid-market EBITDA multiple (say, 5x) to the SDE of a small business where the owner earns $200K above a market manager salary produces a significantly overstated value. Always match the multiple type to the earnings metric type.
Method 3: Discounted Cash Flow (DCF)
DCF values the business based on the present value of its expected future free cash flows. It is the most rigorous method and the most sensitive to assumptions — making it both the most defensible when done well and the most manipulable when done poorly.
The DCF in five steps: 1. Project free cash flow for 5 years based on historical performance and credible growth assumptions 2. Estimate a terminal value at the end of Year 5 (using a terminal growth rate or exit multiple) 3. Select a discount rate (WACC) that reflects the business's cost of capital and risk 4. Discount all projected cash flows and the terminal value back to present value 5. Sum the present values to arrive at enterprise value
For small private businesses, discount rates typically run 20–35% to reflect illiquidity, key-person risk, and lack of diversification — much higher than the 8–12% rates applied to large public companies. This means the terminal value (which is furthest in the future) is heavily discounted, and near-term cash flows dominate the value.
DCF is most reliable when: the business has stable, projectable cash flows; historical performance is a credible basis for projections; and the discount rate can be estimated with reasonable confidence. It is least reliable for: businesses with high owner dependency, unpredictable revenue, or limited track record.
Buyers primarily use DCF as a cross-check against market multiples — to confirm that the multiple they are paying implies a return they can justify on a cash flow basis.
Method 4: Market Comparables
The market comparables method values the business by reference to what comparable businesses have sold for in recent transactions. It is intuitive, grounded in actual market data, and the most common method used in business broker valuations.
How it works: The analyst identifies completed transactions involving businesses of similar size, industry, and quality. From those transactions, they extract key multiples (revenue multiple, EBITDA multiple, SDE multiple) and apply them to the subject business's financial metrics.
Data sources for private company comparables: - BizBuySell data: Aggregates sold listings on the platform; most accessible but skews toward main-street businesses - Pratt's Stats / DealStats: Curated database of verified private company transactions; used by professional appraisers - IBA Market Data: Institute of Business Appraisers transaction database - Capital IQ / PitchBook: Used for mid-market and larger transactions
The limitation of comparables: no two businesses are truly comparable. Differences in geography, customer concentration, growth rate, lease terms, and owner dependency all affect value in ways that raw multiple data does not capture. The analyst's judgment in selecting and adjusting comparables is a significant driver of the concluded value.
For service businesses where comparables are particularly important — and where owner-dependency adjustments most commonly apply — see how to value a service-based business.
Method 5: Asset-Based Valuation
The asset-based method values the business by calculating the fair market value of its assets minus its liabilities. It produces a floor value — what the business is worth if it were liquidated or if its assets were sold individually.
When to use it: - Asset-intensive businesses where physical assets (equipment, real estate, inventory) represent most of the value - Businesses where the going-concern value (what the business earns as a running operation) is less than the asset value - As a floor in any acquisition — you should never pay less than the net asset value for a business
When not to use it as the primary method: - Service businesses, professional practices, and technology companies, where relationships and intellectual property generate most of the value - Businesses with intangible assets (brand, customer lists, proprietary processes) that far exceed balance sheet values
For most small service businesses, the asset-based value is a fraction of the income-based or market-based value. A home cleaning company with $30,000 in equipment and supplies might have an asset value of $25,000 but an SDE-based value of $300,000. The income and market approaches reflect the going-concern value of the customer base and relationships; the asset approach does not.
Key premium drivers across all methods:
| Factor | Direction | Why |
|---|---|---|
| Recurring revenue (contracts, subscriptions) | Up | Predictable cash flow reduces buyer risk |
| Diversified customer base (no single >20%) | Up | Removes concentration risk discount |
| Staff depth / reduced owner dependence | Up | Business operates without the seller |
| Long lease with renewal options | Up | Removes location risk |
| Clean, documented financials | Up | Reduces due diligence risk premium |
| Owner doing 80%+ of revenue-generating work | Down | Key-person risk |
| Top customer = 40%+ of revenue | Down significant | Concentration discount |
| Declining revenue trend (3-year) | Down | Trajectory risk |
| Lease expiring within 12 months | Down | Operational continuity risk |
Frequently Asked Questions
How do you value a small business?
Small businesses (under $2M enterprise value) are most commonly valued using SDE (Seller's Discretionary Earnings) multiples. First, normalize the earnings by adding back the owner's total compensation, personal expenses, and any one-time items. Then apply an industry-appropriate multiple — typically 1.5x–4.0x for main-street businesses, with the specific multiple determined by business quality, growth, and comparable transactions. Cross-check the result against any asset values and review comparable sold businesses in the industry.
What is the difference between SDE and EBITDA in business valuation?
SDE (Seller's Discretionary Earnings) adds back the owner's full compensation — salary, benefits, and personal perks — to the business's earnings. It represents the total economic benefit available to one full-time owner-operator. EBITDA assumes the owner is paid a market-rate salary that stays in expenses; it represents earnings available for debt service, reinvestment, and return to investors above that salary. SDE multiples are applied to small owner-operated businesses; EBITDA multiples are applied to mid-market businesses with professional management. Applying the wrong metric to the wrong multiple produces a materially wrong value.
What multiple should I use to value a business?
The multiple depends on the industry, the size of the earnings, the business's quality, and the buyer type. For small businesses (under $2M revenue), SDE multiples of 1.5x–4.0x are typical, with the average around 2.0x–2.5x for most sectors. For mid-market businesses ($500K+ EBITDA), EBITDA multiples of 3x–8x are common depending on industry and consolidation activity. Higher multiples apply to businesses with recurring revenue, strong management depth, and diverse customer bases. Lower multiples apply to owner-dependent, customer-concentrated, or declining businesses.
How do buyers actually calculate business value?
Serious buyers typically apply at least two methods: (1) a market comparable multiple (SDE or EBITDA) applied to normalized earnings, and (2) a DCF or capitalization of earnings model to verify the implied return. They then stress-test the result by modeling what happens to value if EBITDA drops 20%, if the top customer leaves, or if the owner takes 12 months to transition. The price they offer reflects both the calculated value and their assessment of the risks they are underwriting.
What factors increase a business's value the most?
The factors that most consistently move business value upward are: recurring revenue (contracts, subscriptions, repeat customers), a diverse customer base with no single customer above 20% of revenue, staff depth that allows the business to operate without the selling owner, a long lease with renewal options, and clean, documented financials that require few add-backs. The factors that most consistently depress value are owner-dependence (the seller is the primary revenue generator), customer concentration, declining revenue trends, and short remaining lease terms.
What is a good EBITDA multiple for a small business?
A "good" EBITDA multiple depends entirely on the industry, business size, and market conditions. For small businesses under $500K in EBITDA, multiples typically run 3x–5x. For businesses with $500K–$2M EBITDA, ranges of 4x–7x are common in stable industries. Businesses in sectors with active PE consolidation — healthcare services, home services, specialty trades — can reach higher multiples when platform buyers compete. The DealFlow OS valuation multiples library covers current ranges by industry.
Valuing a business correctly is the foundation of every good acquisition and every successful exit. For buyers, it prevents overpaying on optimistic projections and under-verified earnings. For sellers, it establishes a defensible floor backed by method and market data, not just intuition. The method that matters most is the one whose inputs you can most credibly document: normalized SDE or EBITDA, supported by three years of tax returns and financial statements that tell a consistent story.
