Watch: Business Valuation Methods Explained: SDE Multiple, DCF, Asset-Based, and Market Comps

7 min

Every business owner has a number in their head. Every buyer has a different one. The gap between those numbers is where deals either come together or fall apart, and the method used to arrive at the number determines whether either party can defend their position with evidence. The average small business in the United States sold for 2.61 times its annual cash flow in 2025, generating $7.95 billion in total enterprise value across 9,586 closed transactions, per public and market data. But that average conceals enormous variation — a plumbing company and a car wash on the same street, each generating $200,000 in SDE, can sell for wildly different prices based on risk profile, growth trajectory, and buyer pool.

## The Foundation: SDE vs. EBITDA

Before applying any valuation method, you need the correct earnings metric. Choosing the wrong one is the single most common valuation error.

Seller's Discretionary Earnings represents the total economic benefit available to a single owner-operator: net income plus owner's compensation plus legitimate add-backs minus negative adjustments. Common add-backs include the owner's W-2 salary and payroll taxes, health insurance, personal auto expenses, depreciation, interest on the seller's debt, and above-market family compensation. Common negative adjustments include market-rate rent if the owner occupies the property for free and staffing costs to fill roles the owner performs. SDE is the standard metric for businesses below approximately $1 million to $2 million where the buyer will be an owner-operator. The add-back process — and the costly mistakes sellers make — is detailed in [The $200,000 Mistake: Add-Backs Your Accountant Isn't Telling You About](https://travisbusinessadvisors.com/articles/add-backs-business-valuation-austin-seller-mistake) .

EBITDA strips out financing, tax, and non-cash charges to reveal operational profitability independent of the owner. Unlike SDE, EBITDA does not add back owner's compensation — it assumes the business will pay a market-rate manager. EBITDA is standard for businesses above $2 million, those with professional management layers, and private equity buyers.

The critical distinction: SDE and EBITDA multiples are not interchangeable. A business generating $400,000 in SDE might show $250,000 in EBITDA after deducting a $150,000 manager salary. At 2.8x SDE it is worth $1.12 million. At 4.5x EBITDA it is worth $1.125 million — similar outcomes from different calculations. Applying a 4.5x EBITDA multiple to the $400,000 SDE figure would produce $1.8 million, a 60 percent overvaluation no lender would support.

## Method 1: The SDE/EBITDA Multiple Method

This is the most widely used method for Main Street and lower-middle-market businesses. The formula: business value equals earnings times an industry-derived multiple that reflects risk, growth potential, and desirability.

Current SDE multiple ranges for businesses commonly transacted in Austin: restaurants and food service 1.5x to 2.5x, retail 2.0x to 3.2x, professional services 2.0x to 3.5x, HVAC and plumbing and electrical 2.5x to 3.5x, landscaping 2.0x to 3.0x, construction 2.0x to 3.0x, manufacturing 2.5x to 4.0x, technology and SaaS 3.0x to 5.0x and above, auto repair 2.0x to 3.0x, and car washes 3.5x to 5.0x — per publicly available transaction data, industry valuation reports, and general market knowledge (2025-2026).

The multiple is not a fixed industry constant — it is risk-adjusted for the specific business. Factors that push multiples higher include diversified revenue across many customers, documented standard operating procedures, recurring or contracted revenue, multi-year growth, real estate included, professional management, and strong brand presence. Factors that push multiples lower include high owner dependency — the phenomenon described in [Owner Dependency: The Silent Valuation Killer (And a 6-Month Fix)](https://travisbusinessadvisors.com/articles/owner-dependency-business-sale) — customer concentration exceeding 20 percent in one account as covered in [Customer Concentration Is a Deal Killer. Here's How to Fix It Before Listing.](https://travisbusinessadvisors.com/articles/customer-concentration-selling-business) , declining revenue, deferred maintenance, and pending litigation.

Consider an Austin HVAC company generating $350,000 in SDE with an owner working 50 hours per week handling all estimating, 15 employees, no maintenance contracts, and minimal documentation. At 2.5x SDE: $875,000. If the owner spent 12 months adding maintenance contracts, hiring an estimator, and documenting processes, the same business at 3.2x SDE would be worth $1,120,000 — a $245,000 increase without changing revenue or profitability.

## Method 2: Discounted Cash Flow Analysis

DCF values the business based on what it will generate in the future: project free cash flows for 5 to 10 years, estimate a terminal value, and discount everything to present value using a rate reflecting risk. For private businesses, discount rates typically fall between 15 and 25 percent.

The fundamental weakness is sensitivity. A business projecting $200,000 in annual free cash flow growing at 5 percent produces a 5-year DCF value of $741,000 at a 15 percent discount rate but only $598,000 at 25 percent — a 24 percent swing. At 10 years the swing reaches 40 percent. DCF works well for businesses with predictable, modelable cash flows such as subscription models, long-term contracts, or stable recurring revenue. It adds value when significant growth or decline is expected and when evaluating businesses with substantial future capital expenditure requirements. It is less useful — and potentially misleading — for small owner-operated businesses with volatile earnings, businesses without reliable historical data, and Main Street transactions where buyers and lenders rely on SDE multiples. Most buyers in the $1 million to $5 million range run a DCF as a sanity check. If the SDE multiple method suggests $1.2 million and the DCF produces $900,000 to $1.4 million using conservative assumptions, the methods are converging on a defensible range. If the DCF produces $600,000 or $2 million, the assumptions need examination.

## Method 3: Market Comparable Approach

The market approach asks what other buyers recently paid for similar businesses. Identify 3 to 5 recent comparable sales matched by industry, size, geography, and profit level, calculate the implied multiple from each, adjust for differences, and apply the resulting range to the subject business. Sources include public market databases tracking thousands of closed transactions annually, the IBBA Market Pulse Report, and industry transaction databases.

For Austin specifically, the median sale price reached $349,000 in Q1 2025 with median cash flow of $160,000 and median revenue of $700,000. The approach is grounded in reality — it reflects actual buyer behavior rather than theoretical projections. Its limitations include that truly comparable businesses are rare, databases contain self-reported data that may not capture all terms, and historical data may not reflect current conditions if comparable sales are more than 12 to 18 months old. The reality that identical-looking businesses can produce very different valuations based on specific characteristics is illustrated in [Why Two Identical Car Washes in Austin Can Sell for $800K Apart](https://travisbusinessadvisors.com/articles/car-wash-valuation-austin-800k-difference) .

Market comparables are only as good as the data behind them. Transaction databases — which collectively analyze tens of thousands of closed transactions per year — are among the few accessible sources of real comp data available to business buyers and sellers. They won't tell you what your specific business is worth, but they will tell you what businesses like yours are actually selling for.

## Method 4: Asset-Based Valuation

This method totals the fair market value of all tangible and intangible assets and subtracts liabilities. It is most relevant for asset-heavy businesses — manufacturing, distribution, construction — where physical assets represent a significant portion of value, for wind-down or liquidation scenarios, and as a floor value in any transaction.

For real estate-intensive businesses, the asset-based approach captures value the income approach may understate. A restaurant generating $150,000 in SDE at 2.5x supports a $375,000 business valuation, but if the owner also owns the building worth $800,000, the total transaction must account for both. The dual-asset valuation challenge is covered in [Buying a Business With Real Estate: The Opportunity Most Buyers Overlook](https://travisbusinessadvisors.com/articles/buy-business-real-estate-austin-sba-504) .

## When the Methods Disagree

In practice, the four methods rarely produce identical results. Professional appraisers reconcile differences by weighting each method based on relevance. For owner-operated service businesses, the primary method is SDE multiple with market comps as secondary and asset-based as a floor. For manufacturing or distribution, EBITDA multiple leads with asset-based and DCF as cross-checks. For businesses with real estate, a split approach uses income method for operations and cap rate for the property. The full reconciliation framework for when you receive divergent numbers — and how to determine which is right — is in [I Got Three Different Valuations for My Business. Which One Is Right?](https://travisbusinessadvisors.com/articles/business-valuation-range-austin-which-one-right) .

Regardless of method, SBA lenders apply their own filter: can the business service the acquisition debt? Most lenders require a DSCR of at least 1.25x based on historical tax returns. This constraint effectively caps SDE-based valuations at 3.0x to 3.5x for most Main Street deals financed through SBA 7(a), because the debt service math does not work at higher multiples without substantial equity injection or seller financing.

## The Austin Market Context

Austin-area transactions reflect distinctive characteristics. The median sale price increased to $349,000 in Q1 2025, 4 percent above the prior year. The cash flow multiple across all industries averaged 2.57 in 2024, up from 2.49 in 2023, per public and market data. Service businesses and professional services command premium multiples due to Austin's educated workforce and corporate relocation demand. Real estate-intensive businesses carry dual-valuation complexity that increases average deal sizes — Texas has the highest average SBA loan size of any state at $796,513, per SBA lending data.

## Common Valuation Mistakes

Using the wrong earnings metric — applying EBITDA multiples to SDE or vice versa — produces meaningless results. A $400,000 SDE figure multiplied by a 4.5x EBITDA multiple produces a $1.8 million valuation that no lender will support because the math assumes no owner compensation. Fixating on revenue multiples ignores profitability: two businesses with identical revenue can have vastly different values based on margins. Cherry-picking the single highest comparable sale while ignoring lower comparables that may be more representative is a common seller mistake. Ignoring debt serviceability means producing a valuation the business cannot afford to repay — functionally meaningless for SBA-financed transactions. Conflating asking price with market value produces misleading benchmarks — listings represent what sellers hope to receive, while closed transactions represent what buyers actually paid. Use transaction data, not listing prices.

## When You Need a Professional Valuation

As of June 2025, SBA SOP 50 10 8 requires a third-party valuation for any change-of-ownership transaction where financing exceeds $250,000. The valuation must be ordered by the lender, follow generally accepted standards, and typically costs $3,000 to $10,000 with a 2 to 3 week completion time. A certified appraiser holding ASA, CBA, CVA, or ABV credentials applies all four methods with the rigor required for lending and tax purposes.

Sellers who obtain a professional valuation before listing gain a data-driven asking price defensible to buyers and lenders, identification of value-enhancing improvements, and a smoother due diligence process — addressing the problem described in [Your CPA Loves You. But Their Valuation Is Probably Wrong.](https://travisbusinessadvisors.com/articles/cpa-business-valuation-wrong-austin) . The cost is typically recovered many times over through better pricing and reduced renegotiation.
