Key Takeaways for Dental Practice Owners
- A dental practice valuation is not a single fixed number. It changes based on method, purpose, and who commissions it.
- Free broker estimates and bank collateral figures often anchor low, while a competitive, diligence-grade valuation can produce a bankable market-clearing price.
- Three primary valuation approaches, market (percentage of collections), income (EBITDA multiples), and asset (tangible assets plus goodwill), apply to different buyer types and situations.
- CPA-led normalization of EBITDA, including owner-compensation add-backs, can be critical because every $100,000 of adjusted EBITDA can translate to $600,000–$700,000 in purchase price at typical DSO multiples.
- McLerran & Associates delivers defensible, side-by-side valuations for both private-buyer and DSO markets, backed by CPA-led analysis and a track record of higher transaction success rates.

Three Core Ways To Value a Dental Practice
Three methods are commonly used to value dental practices, and each fits a different situation and buyer type.
- Market approach (percentage of collections). This is the most common method for doctor-to-doctor sales. Private Practice Research's 2026 Baseline Report places general dental practices in private, non-DSO transactions at roughly 65%–85% of annual gross collections. A practice collecting $1 million annually would value at approximately $650,000–$850,000 under this method. This approach ignores profitability, so two practices with identical collections can be worth very different amounts.
- Income approach (EBITDA or SDE). EBITDA, which means Earnings Before Interest, Taxes, Depreciation, and Amortization, is the standard metric for larger practices, multi-doctor groups, and DSO or private equity buyers. It measures what the practice earns after normalizing for owner-specific expenses. Ad Astra Equity's 2026 dental practice valuation framework places typical adjusted EBITDA multiples at 5x–11x, scaling sharply with practice size and buyer type. This method is the primary lens for any institutional transaction.
- Asset approach (tangible assets plus goodwill). This method values the practice's physical assets, such as chairs, imaging equipment, and leasehold improvements, plus its intangible goodwill. It functions as a valuation floor and is most relevant for distressed or rural practices. US Dental Practices reports that roughly 80% of a healthy dental practice's sale price is goodwill, so the asset approach alone usually understates value for a going concern.

Why Dental Practice Valuations Can Differ So Widely
Owners often receive multiple valuation numbers that do not match. The main drivers of those differences can be the method used, the purpose of the valuation, and who commissioned it.
Purpose shapes the assumptions. A valuation prepared for bank financing is built to satisfy a lender's collateral requirements. A valuation for a divorce proceeding applies a different legal standard of value. An internal associate buy-in uses different transfer assumptions than an open-market sale. Under the AICPA SSVS No. 1 framework, a valuation is a conclusion about a defined interest on a specified date for a stated purpose. Changing any one of those variables can change the answer.
The party who commissions the number also matters. A buyer-supplied free valuation is not an independent analysis. It is the output of an underwriting model designed to generate returns for the buyer. Windsor Drake states that a DSO's opening offer is anchored by buyer-controlled assumptions about provider retention, payer mix durability, and operational leverage that the seller typically cannot see. That number becomes the anchor for every negotiation that follows. Owners who accept it without an independent, diligence-grade valuation can end up negotiating against themselves.
The advisor category also shapes the outcome. Consider the trade-offs across the common options.
- Do-it-yourself / for-sale-by-owner: The valuation is set by the buyer, with no competitive tension or independent analysis; close rates run approximately 15%–20%.
- Local generalist broker: Limited market exposure, weaker underwriting, and relationships with only 1 or 2 buyers; DSOs bid less aggressively on infrequent listings.
- Multi-vertical advisor: Broader deal experience across many industries, but without the dental-only focus needed to read specialty dynamics or maintain a vetted national buyer pool.
- Free-valuation lead-generation firm: A back-of-the-napkin number used to attract a listing; the analysis is not built to withstand buyer scrutiny.
- Association benchmark or online calculator: Generic by design. Dentx.ca's 2026 guide notes that an online calculator gives a conservative starting estimate but does not replace a formal analysis that reviews tax returns, production reports, payer contracts, the lease, equipment, and local market comparables.
McLerran & Associates serves as a primary advisor for owners who want a practice-specific, side-by-side valuation. The firm provides a private-buyer number and a DSO number, both supported by CPA-led analysis that is built to hold up when buyers review the details. Its roughly 50/50 split between private-buyer and DSO transactions means owners see their worth in both markets before choosing a path. For more on how dual-agency conflicts can affect the number you receive, see How Broker Dual Agency Can Affect Your Practice Valuation.
EBITDA and Add-Backs: Establishing True Profitability
While the advisor you choose shapes the valuation, the underlying numbers can matter just as much. A key driver is EBITDA, which needs to be normalized before anyone can rely on it.
Normalized EBITDA reflects what the practice would earn under new ownership. The process removes the owner's personal and discretionary expenses and substitutes a market-rate clinical salary for the owner's actual compensation. McLerran's CPA-led process pulls practice-management software reports, cross-references them against financial statements and tax returns, and unpacks every discretionary, personal, and non-recurring expense to arrive at true profitability.
The stakes can be high. At the 6x–7x multiples common in DSO offers, every $100,000 of normalized EBITDA is worth $600,000–$700,000 of purchase price. The quality and defensibility of each add-back can become a central valuation issue. The owner-compensation normalization resets the owner's pay to a market clinical rate, typically around 28%–32% of production for a general practitioner. This is the most contested add-back in quality-of-earnings diligence and often produces $80,000–$300,000 in normalized EBITDA uplift for solo-producer practices.
A weak analysis rarely survives diligence. Approximately 85% of lower-middle-market deals see a post-LOI price adjustment, almost always downward, and buyers usually expect those adjustments. In one example, a seller claiming $1.1 million of adjusted EBITDA but documenting only $800,000 would lose $1.8 million of enterprise value at a 6x multiple when the buyer removes the unsupported $300,000. The practice did not change, but the number could not be documented. McLerran's valuations are built to prevent that outcome. The homework is done before the deal goes to market, so the agreed value can hold when buyers scrutinize it.

Goodwill and Chart Value in Dental Practice Sales
Goodwill is the value of a practice's patient relationships, reputation, trained staff, location, payer contracts, and recall systems. It represents everything that makes the practice worth more than its physical assets. For a healthy general dental practice, goodwill can represent approximately 80% of the sale price, so it can be the largest and most easily damaged asset in any transition. Active patient records are sometimes benchmarked on a per-chart basis as a secondary check, although the income approach usually remains the primary method for going-concern practices.
A critical distinction in any valuation is between enterprise goodwill and personal goodwill. Enterprise goodwill arises from the practice's systems, location, brand, payer contracts, and multi-provider continuity. This value can transfer to a new owner. Personal goodwill arises when patients or referral sources are attached to a specific dentist rather than to the practice itself. IRS materials state that the loss of the manager of a one-person business can depress value if trained successors are lacking, so a founder-dependent dental practice typically suffers a sharper goodwill reduction in a sale. Many industry sources repeat this owner-dependence theme, and it can be one of the highest-leverage variables an owner can address before going to market.
Private Buyer vs. DSO: Comparing Valuation Paths
The 2 main buyer markets for dental practices use different metrics and deal structures and can produce very different numbers for the same practice. Doctor-to-doctor deals are typically priced on a percentage of revenue or a multiple of net cash flow, often called Seller's Discretionary Earnings (SDE), which is net income plus owner compensation and discretionary expenses. DSO and private equity deals are priced on a multiple of normalized EBITDA, which resets owner compensation to a market associate rate before applying the multiple.
Private Practice Research's 2026 Baseline Report describes a two-tier market in which DSO acquisitions can carry a 40%–80% premium over private-buyer valuations. A $2 million revenue practice with 20% EBITDA margins ($400,000 EBITDA) might transact at $2.4M–$2.8M to a DSO buyer at 6x–7x, versus $1.3M–$1.7M to a private buyer at 65%–85% of collections. That gap can be meaningful. DSO deals commonly pay roughly 60%–75% of the headline valuation in cash at closing, with the remainder in rollover equity and earnouts, so the selling dentist does not receive the full headline number at closing. Rollover equity, which is stock in the DSO, is illiquid, carries platform risk, and should be underwritten like any investment.
Owners who could reasonably pursue either path often benefit from seeing both numbers before choosing. Because McLerran & Associates works private-buyer and DSO transactions in roughly equal measure, it produces a side-by-side valuation that quantifies the practice's worth in both markets. Single-lane advisors cannot provide that comparison. For a fuller picture of what owners give up by going it alone, see Dental Practice Sale Without Broker: Why Owners Lose More.
What Can Move Your Practice Value Up or Down
Several practice-specific factors can move your final sale price up or down. The most impactful ones are backed by current industry data.
- Owner dependence. Practices where the selling doctor produces 90% or more of clinical revenue consistently see valuation reductions of approximately 10%–20%, because a buyer cannot underwrite production revenue that leaves with the seller.
- Hygiene production ratio. Hygiene revenue above 30% of collections can be tied to premium multiples and stronger DSO offers, because it signals recurring revenue that continues regardless of which dentist is in the chair.
- Payer mix. Payer mix can be one of the largest drivers of dental practice multiples, with higher fee-for-service revenue potentially worth several full multiple turns more than equivalent Medicaid or HMO earnings.
- Overhead. Two practices each collecting $1 million can differ by roughly $300,000 in value based on overhead alone, such as one running 55% overhead versus one running 72% overhead.
- Revenue durability and trend. Buyers treat a declining collections trend as a forecast. A practice that slid from $1.4 million to $1.2 million over 3 years is valued differently from one that grew from $950,000 to $1.2 million, even at the same current collections.
- Number of doctors and expandability. Multi-provider practices with associate depth can reduce transition risk and may access higher EBITDA multiple tiers.
- Location. DSO acquisition activity concentrates in metropolitan areas, with equivalent-revenue metro practices pricing 30%–40% above rural peers in many markets.
- Specialty demand. Specialty practices carry distinct buyer dynamics and multiple ranges. Oral and maxillofacial surgery and orthodontics often draw strong institutional interest, while lighter-demand specialties can sit at the lower end. Your advisory team can provide practice-specific guidance.
The multiple a buyer offers usually reflects your practice's specific numbers and market, not a fixed table. Every benchmark range in this article describes the U.S. dental market broadly rather than any single practice.
Defending the Number Through Diligence
A valuation that cannot survive buyer scrutiny functions as a starting point for a price reduction. The re-trade, when a buyer uses diligence findings to push the agreed price down after exclusivity begins, can be one of the most common ways sellers lose value quietly. Once a letter of intent is signed, competing bidders go home. The seller then negotiates alone against a clock. That is precisely when unsupported add-backs can get removed and multiplied away at the multiple.
McLerran & Associates builds quality-of-earnings defense into the process from the start. Because the CPA-led analysis is done before the deal goes to market, the numbers can hold when buyers review the details. The firm reports a transaction rate of approximately 85%–90% among its clients, versus an industry norm closer to 35%–40%. That gap reflects both the quality of the upfront work and the competitive process that creates leverage throughout diligence.
The impact of a diligence-grade valuation can be significant. In one case, a practice a free valuation pegged at $2.5 million was valued by McLerran & Associates at $4.5 million and sold for $5.25 million after a competitive process. The free number served as an anchor rather than a defensible value. McLerran's clients typically achieve approximately 30% higher valuations than owners who sell on their own, a result of both the quality of the analysis and the competitive bid process that often generates around 10 offers over a 45–60-day window.

Frequently Asked Questions
What Is the 80/20 Rule in Dentistry?
In the context of dental practice valuation, the 80/20 rule most commonly refers to the observation that roughly 80% of a healthy dental practice's sale price is attributable to goodwill, the intangible value of patient relationships, reputation, trained staff, location, and recall systems, with about 20% attributable to tangible assets like equipment and leasehold improvements. A secondary application of the rule describes revenue concentration. When 80% of a practice's production comes from 20% of its procedures or patients, buyers flag that concentration as a risk factor that can compress the multiple. Both applications highlight that transferability of value can matter more than the headline revenue number.
How Much of a Dental Practice's Value Is Goodwill?
As mentioned earlier, goodwill often makes up about 80% of a practice's sale price. That share can be higher for practices with strong associate production, diversified payer mix, and deep patient recall systems, and lower for practices where most value is tied to the departing owner personally. The distinction between enterprise goodwill, which can transfer, and personal goodwill, which may not, can be one of the most consequential issues in any dental practice sale and is a central focus of a diligence-grade valuation.
Is a Free Dental Practice Valuation Accurate?
A free valuation typically functions as a lead-generation tool rather than a diligence-grade analysis. It may use a percentage-of-collections rule of thumb or a generic EBITDA estimate without pulling practice-management reports, cross-referencing financials, or unpacking add-backs. The result is a number that looks authoritative but has not been tested against the data a buyer's quality-of-earnings team will examine. When that team arrives on an institutional transaction, unsupported add-backs can get removed and multiplied away at the multiple. A free valuation that anchors the negotiation low, or that collapses in diligence, can cost far more than the fee a diligence-grade analysis would have required.
Should I Get a Broker or an Appraiser?
The right answer depends on the purpose. A certified appraiser producing a formal Conclusion of Value under AICPA SSVS No. 1 can be appropriate for divorce proceedings, estate planning, partner buy-ins, or any matter that may end up in court or before a tax authority. For an actual market sale, where the goal is to maximize proceeds and close a deal, a dental-specific, CPA-led sell-side advisor can be the more suitable choice. McLerran & Associates occupies that role. Its valuations are CPA-led and diligence-grade, built not just to establish a number but to defend it through the full transaction process. The firm is sell-side only, so its incentives align with the seller at every stage.
Is My Practice My Retirement?
For many dental practice owners, the practice is the single largest asset on their personal balance sheet, often worth more than their home, retirement accounts, and other investments combined. That reality makes the valuation number both a transaction figure and a retirement planning figure. An inaccurate or undefended number can affect the sale price and the owner's financial security for decades. Owners within 10 years of a planned transition can benefit from understanding what their practice is worth, in both the private-buyer and DSO markets, before a buyer arrives with their own number.
Conclusion: Choose a Number You Can Explain and Defend
A dental practice valuation reflects a negotiation and a process outcome rather than a single fact to look up. The same practice can receive three different numbers depending on method, purpose, and who commissioned the work. A CPA-led, diligence-grade valuation that can withstand quality-of-earnings scrutiny can be the most bankable version of that number.
McLerran & Associates serves as a dental practice valuation advisor for owners who need a defensible, bankable number. Its valuations are CPA-led and diligence-grade, the firm has evaluated more than 10,000 dental practices, and it works both the private-buyer and DSO paths in roughly equal measure so owners see their worth in both markets. The evaluation criteria that can matter most include a dental-only focus, CPA-led valuation, access to both transition paths, a competitive process that creates the market rather than accepting one buyer's anchor, and quality-of-earnings defense that helps the agreed value hold through closing. McLerran & Associates has approximately 2,000 successful practice sales and approximately $2 billion in closed transaction volume built on that foundation.
