How to Value a Private Business for Sale in 2026: 5 Methods Every Owner Should Know

Most owners who try to value a private business start with the wrong question. They ask what the business is worth in a vacuum, when the real question is what a specific buyer will pay on a specific day under a specific deal structure. Private business valuation is not a single number. It is a defensible range that holds up against a buyer’s model, a lender’s underwriting, and a QoE firm checking the books line by line.

This guide walks through how to value a private business the way the buy side actually does it: the three approaches (income, market, asset), the SDE vs EBITDA breakpoint, the comparable transaction databases, the adjustments that move your number, and when a sell-side Quality of Earnings is worth $25,000 to $75,000. We close with a full worked example on a $1.5M revenue plumbing owner-operator and an 8-question FAQ.

The three approaches to value a private business

Every credentialed appraisal, every banker pitch deck, and every QoE memo reduces to the same three approaches. The art of private business valuation is knowing which one carries the most weight for your business and what the buy side will actually accept.

Income approach: capitalize what the business earns

The income approach asks one question: what is the present value of the cash this business will throw off? Two methods dominate. DCF projects 5 to 10 years of free cash flow and discounts back at WACC. Capitalization of earnings takes a normalized earnings number and multiplies by an industry-anchored multiple.

For owner-held businesses under $25M revenue, capitalization dominates. Buyers do not run 10-year DCFs on a $4M plumbing company; they take LTM SDE or EBITDA, apply a DealStats-anchored multiple, and call it a day. DCF returns when future cash flows diverge materially from trailing run rate (software growing 40%/yr, healthcare roll-ups with committed pipeline).

Our deeper breakdown lives at how to value a small business for sale, which covers the buyer side mechanics in more detail. For the broader small-business framework (including non-cash-flow methods and asset-heavy edge cases), see how to value a small business.

Market approach: anchor on closed comparable deals

The market approach is the workhorse for LMM private business valuation. Find businesses similar to yours that recently sold, observe the multiple the buyer paid (price / SDE or EBITDA), and apply that multiple to your earnings. The whole exercise hinges on comp set quality.

Four comparable transaction databases dominate:

• DealStats (Business Valuation Resources): largest searchable database of private company transactions, ~41,000 closed deals tagged by NAICS, revenue band, and earnings multiple. The database most credentialed appraisers (ASA, CVA, ABV) actually run.
• PitchBook: strongest on middle and upper middle market PE transactions, $10M to $1B enterprise value. The buy side uses it to underwrite platform deals; sellers use it to benchmark sponsor activity.
• IBBA Market Pulse: quarterly survey of Main Street and LMM brokers across 5 deal-size bands ($500K to $50M). Multiple ranges, days on market, buyer types. Free summary, paid full report.
• BizBuySell Insight Report: quarterly snapshot of listed and sold small businesses on the largest U.S. business-for-sale marketplace. Skews Main Street ($100K to $2M sale price), useful for sub-$1M SDE comps.

One-database setup: DealStats. Two-database setup: DealStats plus IBBA Market Pulse. That is what most independent appraisers carry into a credentialed report.

Asset approach: floor value, not market value

The asset approach sums the fair market value of tangible assets (equipment, vehicles, real estate, inventory) plus identifiable intangibles (customer lists, trademarks, software), minus liabilities. For an operating company with positive cash flow, it almost always produces a number well below the income or market result. That is the point: it gives you a floor.

The asset approach becomes the primary method only when the business is asset-heavy with negligible earnings (a holding company with real estate), being liquidated rather than sold as a going concern, or sold as an asset purchase rather than an entity purchase. For owner-operated businesses with consistent earnings, treat it as a sanity check.

SDE vs EBITDA: the breakpoint that decides your private business valuation

Whether the market values your business in SDE multiples or EBITDA multiples is the single most important decision in private business valuation, because it changes both the earnings number and the multiple. Get this wrong and your asking price is off by 30 to 50 percent.

Seller’s Discretionary Earnings (SDE) adds back full owner comp, benefits, perks, and non-cash expenses to net income. It assumes the buyer replaces the owner with themselves, takes home the same cash, and does not pay a market-rate manager. SDE is the right metric for owner-operators working 40+ hours a week with total comp under roughly $250,000.

EBITDA (earnings before interest, taxes, depreciation, amortization) does not add back owner comp. It assumes the buyer hires a market-rate GM ($100,000 to $250,000 depending on sector and geography) and runs the business as an investment, not a job. EBITDA is the right metric for management-run businesses, replaceable-owner businesses, and any business with $1M+ in cash flow.

Practical breakpoint: around $1M in earnings. Below $1M, the deal market quotes SDE multiples and the buyer pool is individuals, search funds, and small holding companies. Above $1M, the market quotes EBITDA multiples and the buyer pool tilts to LMM private equity, family offices, and strategics.

The full mechanics of the swap (including how the same business can carry a 3.5x SDE multiple and a 5.5x EBITDA multiple simultaneously) are covered in SDE vs EBITDA business valuation.

Quick example of the SDE to EBITDA swap

Consider a $4M residential HVAC company with $800K net income. The owner pays themselves $180K, runs $40K of personal vehicle and travel through the business, expenses $25K family health, and has $60K depreciation.

• SDE = $800K + $180K + $40K + $25K + $60K = $1,105,000
• EBITDA = SDE minus $150K market-rate HVAC ops manager = $955,000

At 3.5x SDE the value is $3.87M. At 5.0x EBITDA the value is $4.78M. Same business, two earnings frames, $900K of valuation difference. The above-$1M buyer pool pays the higher EBITDA multiple because they are buying an investment, not a job, and they are baking in the GM expense.

Real industry multiple ranges (2026 market data)

Before commissioning any appraisal, anchor on the multiple range your sector actually trades in. The ranges below blend DealStats LTM transaction data, IBBA Market Pulse Q1 2026, PitchBook LMM reports, and our own buy-side deal flow across 76+ active U.S. buyers.

Notice the spread inside each row. A $1.5M EBITDA HVAC company in Phoenix with 35% residential recurring service plans, dense route geography, and a working ops manager clears the top of the range (8x to 9x EBITDA). The same earnings number with 80% new-construction work, no service agreements, and the owner as the only estimator clears the bottom (4x to 5x). Same earnings, double the enterprise value, driven entirely by what the buy side considers buyable.

How to find comparable transactions for your business

If you are not paying for DealStats or PitchBook directly, you still have credible paths to comp data. Most owners stop too early.

Free and low-cost comp sources

• BizBuySell Insight Report (free quarterly). Median sale price, revenue and cash flow multiples, days-on-market by sector and region.
• IBBA Market Pulse (free summary, paid full ~$300). Quarterly broker survey across 5 deal-size bands ($500K-$50M+); multiples with bid-ask spread.
• Axial (free seller newsletter). Active deals with revenue, EBITDA, and asking multiples in the LMM range.
• SBA 7(a) loan data (USAspending.gov). Loan + seller note + down payment back-solves to purchase price for sub-$5M SBA deals.

What makes a comp actually comparable

A clean DealStats search returns 80 to 400 deals in a popular NAICS code. Do not average all of them. Strip the comp set to deals that match yours on at least four of these six axes:

1. Size: revenue within 50% of yours, cash flow within 40%.
2. Geography: same Census region minimum; same state ideal for service-area businesses.
3. Sub-sector: residential plumbing is not commercial mechanical; pediatric dental is not general dental.
4. Recurring mix: service-agreement-heavy businesses trade 1.0x to 2.0x above project-based peers.
5. Growth rate: trailing 3-year revenue CAGR within 5 percentage points.
6. Recency: closed inside the trailing 24 months; older comps reflect a different rate environment.

Five to twelve clean comps beat fifty messy ones every time. The trimmed set gives you a defensible median and interquartile range you can present to a buyer without flinching.

The four adjustments that move your number the most

Once you have a comparable multiple anchored, the next question is whether your business lands at the top, middle, or bottom of the range. Four adjustments dominate.

Size premium

Larger businesses sell for higher multiples of the same earnings. A $500K SDE landscape company trades 2.8x to 3.5x. A $3M EBITDA landscape company trades 5.5x to 7.5x. The same dollar of profit is worth roughly twice as much inside the bigger entity, because of deeper management bench, lower concentration risk, eligibility for institutional buyer pools, and bank debt instead of seller financing. If you are within 18 months of the next size tier, holding the sale to cross that threshold is often the highest-ROI lever you have.

Growth rate

A business growing 15% per year trades 0.5x to 1.5x above a flat peer. A business growing 25%+ that can defend the growth into the forecast period can clear 2.0x premium. A business in trailing decline trades 0.5x to 1.5x below, and many buyers exit the process entirely.

Recurring revenue mix

Recurring revenue (membership plans, service agreements, MSP contracts, SaaS subscriptions) is valued well above transactional revenue. In home services, 40%+ revenue from service agreements typically clears 1.0x to 2.0x EBITDA above a transactional peer. In SaaS, ARR with 110%+ net revenue retention clears multiples no other business model can touch.

Customer concentration

The fastest way to compress your multiple is one customer over 20% of revenue, or two customers over 35% combined. Buyers underwrite to the worst case (that customer leaves at close) and discount accordingly. A 25%-concentrated business typically loses 1.0x to 2.0x EBITDA off the median, and the buyer will often require an earnout to bridge the remaining gap.

When to commission a sell-side Quality of Earnings

A sell-side Quality of Earnings (QoE) is the biggest lever an owner has between the back-of-envelope number and the price they actually clear at close. A QoE is a forensic accounting report from an independent CPA firm that normalizes EBITDA, validates revenue recognition, identifies one-time items, and stress-tests working capital. It runs $25,000 to $75,000 for LMM deals and is now expected upfront from any credible sale.

Commission a sell-side QoE when:

• Your trailing EBITDA is $1M or more (below that, the cost is hard to justify against deal size).
• You expect the buyer pool to include private equity or family offices (they assume a QoE will exist; if you do not produce one, they will commission their own and the findings will drive purchase price down, not up).
• Your financials have any complexity: multi-entity structure, intercompany activity, related-party leases, owner add-backs over $200K, cash sales, or revenue recognition that is not pure point-of-sale.
• You want to defend your asking price against a re-trade. The single highest-stakes moment in any LMM transaction is the gap between LOI signing and definitive agreement, when the buyer’s diligence team finds reasons to renegotiate. A sell-side QoE is your defense.

Full QoE scope, cost, and timeline are at our Quality of Earnings guide. Plan 4 to 6 weeks of fieldwork and budget it as a deal-close expense, not overhead.

Why CPA-style valuation and M&A-style valuation produce different numbers

One of the most expensive mistakes is taking your long-time tax CPA’s number to market. The CPA is not wrong. They are answering a different question.

CPA-style valuation (calculation of value, tax-purpose valuation) is built for IRS audit defense, estate planning, divorce, partnership buyouts, and shareholder disputes. The methodology applies conservative discount rates, large discounts for lack of marketability (DLOM) and lack of control (DLOC), and rarely incorporates strategic-buyer synergies. The number is defensible to a court or the IRS, which means it sits below what a competitive buyer auction produces.

M&A-style valuation (market-clearing, transaction-purpose) asks what a real buyer in the current market will actually pay, with all add-backs, synergies, and strategic premiums on the table. It anchors on recent closed comps, runs SDE-to-EBITDA conversions explicitly, and prices in buyer-pool competition. The number is what the LOI reflects.

On the same business, the spread between the two can be 30% to 60%. The CPA number is correct for its purpose. It is the wrong anchor for your asking price. Deeper at accountant vs M&A advisor. For how the buy side actually models, see how investment bankers value a business.

Worked example: value a private business owned by a $1.5M revenue plumbing owner-operator

Concrete numbers beat methodology. Full private business valuation walkthrough on a representative residential plumbing company.

The company

• Revenue (LTM): $1,510,000
• Reported net income: $215,000
• Owner role: 25 hours/week in the field, 20 hours/week running estimates and dispatch; age 58, retiring in 18 months
• Headcount: 1 owner, 4 service techs, 1 part-time dispatcher
• Service mix: 72% residential service/repair, 18% residential repipe/remodel, 10% small commercial
• Recurring: 320 active service agreement members at $16/month, about 6% of revenue
• Customer concentration: none over 4% (clean)
• Trailing 3-year revenue CAGR: 8%
• Market: single MSA, 1.2M population, moderate competition

Step 1: Normalize earnings to SDE

SDE of $414K places this business clearly in the sub-$1M cash flow band, which means the market quotes in SDE multiples and the buyer pool is individuals, search funders, holding companies, and small home services platforms.

Step 2: Anchor the multiple in comparable transactions

DealStats query: NAICS 238220, residential service, $1M to $2.5M revenue, closed 2024 to Q1 2026. 27 transactions; 11 clean comps after filtering for size, geography, and sub-sector fit.

• Median SDE multiple: 3.2x
• Interquartile range: 2.7x to 3.8x
• Top quartile (recurring-heavy, dense routes): 4.0x to 4.5x

IBBA Market Pulse Q1 2026 confirms: residential trades sub-$2M revenue trading 3.0x to 3.4x SDE median, with recurring-revenue businesses at the upper end.

Step 3: Apply the adjustments

• Size: middle of band, no adjustment.
• Growth: 8% trailing CAGR is above sector median (around 5%), modest +0.2x premium.
• Recurring mix: only 6% from service agreements, well below the top-quartile threshold of 25%+. No premium.
• Customer concentration: clean (no customer over 4%). No discount.
• Owner dependency: owner runs estimates and dispatch; high. -0.3x discount for the transition risk.

Net adjusted multiple: 3.2x base + 0.2x growth – 0.3x owner dependency = 3.1x SDE.

Step 4: Calculate enterprise value

3.1x × $414,300 SDE = $1,284,000 enterprise value

For an SBA-financeable residential trades deal, that typically structures as: $1.0M cash at close, $200K seller note at 8% over 5 years, $84K in a 12-month earnout tied to revenue retention. Inventory ($45K) and accounts receivable handling are negotiated separately.

Step 5: The “what if” levers

The same business in 12 months, with deliberate work, can clear $1.55M to $1.75M:

• Grow service-agreement base from 320 to 800 members (+19% recurring mix, +0.6x multiple)
• Promote senior tech to dispatch/estimating, removing owner from daily ops (kills the -0.3x discount)
• Hit $475K SDE on 10% organic growth plus the membership uplift

3.7x × $475K = $1,757,000. That is a $470K delta to the owner on the back of roughly $40K of process work and one hire. Full menu in what actually affects your business valuation in a sale.

How to validate your private business valuation before going to market

Once you have a number, validate it three ways before building an asking price around it:

1. Run the same exercise in EBITDA (if earnings are above $1M) and check the two ranges overlap. If SDE math says $4.2M and EBITDA math says $5.8M, something is wrong (usually a missing add-back or a misapplied multiple band).
2. Pressure-test with our valuation tool. The free valuation survey returns a range from DealStats + IBBA comp data. If your number is more than 25% outside it, the assumptions need a second look.
3. Get a buy-side read. The fastest sanity check is a confidential conversation with a firm that talks to your buyer pool every week. Our 30-minute strategy call is free, no retainer, no contract.

For the buyer pool itself (the 76+ active U.S. LMM buyers we work with directly), see the partners page.

The big mistakes owners make in private business valuation

Patterns we see across hundreds of LMM conversations:

• Anchoring on revenue. “We did $8M last year” is not a valuation statement. An $8M business at 4% margins is worth a fraction of a $3M business at 22% margins.
• Quoting SDE on a business the market values in EBITDA. Owners with $1.5M EBITDA who add back $250K of their own comp and quote “$1.75M SDE × 4x = $7M” systematically over-price. The buyer pool above $1M values EBITDA, not SDE.
• Stale or apples-to-oranges comps. A 2022 strategic-platform transaction at 11x EBITDA is not a valid comp for a 2026 single-location sub-$1M EBITDA sale.
• Ignoring working capital peg. Roughly 90% of LMM deals are sold cash-free, debt-free with a working capital peg. The peg moves your final wire 5% to 10% of enterprise value. Plan for it.
• Treating the appraisal as the asking price. An appraisal is a defensible point inside a range. Your asking price is a market-clearing number, usually 10% to 25% above the point estimate to leave negotiation room.

Frequently asked questions about private business valuation

What is the average multiple to value a private business?

For sub-$1M cash flow businesses, the market median is roughly 2.8x to 3.5x SDE across sectors per IBBA Market Pulse and DealStats LTM data. For $1M to $5M cash flow it is roughly 4.5x to 6.5x EBITDA. Healthcare, software, and platform-eligible trades businesses clear materially higher; transactional and project-based businesses with high concentration clear lower. Anchor on your specific sector and size band, not a blended average.

Should I use SDE or EBITDA?

Use SDE if you are an owner-operator working 30+ hours/week with total owner comp under ~$250,000. Use EBITDA if earnings exceed $1M, a market-rate GM could run the business without you, or the buyer pool will include PE or family offices. In the $750K to $1.5M gray zone, run both and present both ranges.

How much does a sell-side Quality of Earnings cost?

$25,000 to $75,000 for LMM deals, most landing $35K to $55K. Cost scales with revenue size, chart-of-accounts complexity, legal-entity count, and whether the firm builds a normalized TTM adjusted EBITDA from scratch versus tying out an existing one. The investment is typically recovered many times over in defended purchase price; the alternative is a buyer-led QoE that finds reasons to re-trade.

CPA valuation vs M&A valuation?

A CPA valuation is built for tax, estate, and litigation defensibility, applying conservative discount rates and DLOM/DLOC discounts that push the number down. An M&A valuation clears the market: anchored on recent comps, prices in strategic premiums, explicit SDE/EBITDA conversions. Same business, the two can differ 30% to 60%. Only the M&A number should drive your asking price.

How long is a private business valuation good for?

6 to 12 months under stable conditions. Any material change (loss of a top customer, 200+ bps interest rate move, a sector-defining transaction, new regulation) resets the clock. Owners 24+ months from market should refresh annually.

Can I value my private business without DealStats or PitchBook?

Yes for sub-$5M deals. The free BizBuySell Insight Report, IBBA Market Pulse summary, Axial deal flow, and SBA 7(a) loan database give enough data to triangulate. Above $5M enterprise value, comp quality drops sharply without paid databases; the cost of even a 10% mis-pricing easily justifies a one-time DealStats pull through an independent appraiser (~$1,500 to $3,000).

Does owner dependency really lower the multiple?

Yes, and it is the largest discretionary discount in LMM private business valuation. An owner who holds the top customer relationships, is the only estimator, or makes every operational decision typically costs 0.5x to 1.5x off the median multiple. Fix: promote or hire a GM, document SOPs, distribute customer relationships, and ideally run at arm’s length 6 to 12 months before going to market.

What does a buyer need to underwrite a defensible price?

3 years of P&L and balance sheets, TTM monthly P&L, full general ledger for the last 12 months, customer concentration analysis (top 10 / % revenue, last 3 years), employee roster with comp and tenure, equipment list with age, and add-back schedule with support. A sell-side QoE bundles all of this. Full checklist in our Quality of Earnings guide.

Next step: anchor your number in real buy-side data

Private business valuation is not a one-shot deliverable. It is a working range you refine as the deal comes together. The two fastest ways to get from a guess to a defensible range: the free valuation tool (5 minutes, real deal comps) and a confidential 30-minute strategy call. Both free, both before any retainer or contract. The goal: walk into your sale with the same numbers the buyer is using on the other side of the table.
