Key Takeaways
- Most dentists’ largest financial asset is their practice, so knowing how to estimate its value can be essential for retirement, partnerships, and sale planning.
- Rules of thumb, such as 60–85% of 3-year average collections, give a quick ballpark but overlook profitability, growth, and buyer type.
- Private-buyer deals often use 1.5–3× SDE, while DSO and private-equity deals often use 4–13× EBITDA, which can create very different prices for the same practice.
- A DIY estimate can be a starting point. A professional, CPA-led valuation is more likely to hold up during buyer due diligence and reduce the risk of price cuts.
- McLerran & Associates offers side-by-side valuations for both private-buyer and DSO paths so you can compare options before choosing a direction. Get your side-by-side valuation to see what your practice may be worth.
The Quick Rule of Thumb: 60–80% of Collections
One of the most frequently cited rules of thumb for valuing a dental practice is 0.6 to 0.8 times annual gross revenue (collections), though some sources cite 65–85% or 60–75% of collections. For a solo general practice, EBITDA multiples often range from about 3× to 5×, with some sources citing 2.5×–4× or 4×–6×, depending on buyer type and practice characteristics. Many advisors use these figures as a starting point for a rough estimate.
Rules of thumb can help with a quick sanity check, but they carry significant limitations.
- They ignore profitability. Two practices with identical collections can differ by hundreds of thousands of dollars in value if one runs a 55% overhead ratio and the other runs 75%. Overhead ratio is the percentage of gross revenue consumed by operating expenses. Lower overhead usually means higher profitability.
- They ignore growth trends, patient demographics, and payer mix. A practice growing 10% year-over-year can be worth more than a flat or declining one at the same revenue level.
- They ignore the single biggest variable: who the buyer is. A private buyer and a DSO use different valuation methods and apply different multiples to the same practice.
A rule of thumb can show whether you are in the right ballpark. It does not usually produce a number that will survive a buyer’s due diligence review.
Three Core Valuation Approaches for Dental Practices
Professional appraisers generally use three recognized methods. The right method can depend on the practice and the purpose of the valuation.
Asset-Based Approach
This method adds the fair market value of tangible assets, such as equipment, supplies, and technology, plus intangible assets such as goodwill and patient records. It can be most relevant for startup practices, struggling practices, or situations where earnings do not support a higher income-based value. For a profitable, established practice, this method usually produces the lowest number and is rarely the primary method in a sale.
Income-Based Approach
This method focuses on the practice’s ability to generate future income and is often the most relevant approach for a sale. It splits into two calculations based on buyer type: SDE for private buyers and EBITDA for DSOs. The step-by-step examples below use this approach.
Market-Based Approach
This method compares the practice to similar practices that have recently sold in the same region. It is the source of valuation multiples, which are the numbers applied to SDE or EBITDA to arrive at a purchase price. Multiples vary by specialty, region, practice size, and market conditions. They are best viewed as ranges influenced by fundamentals rather than fixed tables. For a deeper look at how multiples are derived, see McLerran’s guide on how dental practice valuation multiples are calculated.
Step-by-Step: Estimating Value Using Gross Collections
This method is one of the fastest ways to generate a rough value band. Follow these three steps.
- Determine average annual gross collections over the last 3 years. Pull the total production collected (not billed) for each of the past 3 years and calculate the simple average.
- Apply the 60–80% range. Multiply the average collections figure by 0.60 and by 0.80 to create a rough value band.
- Adjust for practice-specific factors. Shift within or outside the band based on overhead ratio, patient concentration, location, and growth trend. High overhead or high patient concentration can push the value toward the lower end or below it. Strong growth and low overhead can push it higher.
Dr. Smith’s practice averaged $1.2 million in gross collections over the last 3 years. At 70%, that equals $840,000. Dr. Smith’s overhead runs 75%, which is well above the 60–65% benchmark for a healthy practice. A knowledgeable buyer would likely discount that number, so his value in this method might land closer to $700,000–$750,000.
This method gives a ballpark. It does not fully account for the practice’s true profitability, which can be one of the main drivers of value in a real transaction.
Step-by-Step: Estimating Value Using SDE and EBITDA
The income-based approach usually produces a more detailed and defensible number. The method shifts based on who the buyer is.
SDE (Seller’s Discretionary Earnings) for Private-Buyer Sales
SDE is the total economic benefit an owner-operator receives from the practice. It includes net profit plus the owner’s salary, personal perks, and any discretionary or non-recurring expenses that run through the business. A private buyer, another dentist, is buying a job as well as an investment. They will work in the practice, so they focus on what the practice pays the person in the chair.
To calculate SDE:
- Start with net profit from the practice’s tax return or profit-and-loss statement.
- Add back the owner’s salary and any owner benefits, such as health insurance and retirement contributions.
- Add back personal expenses run through the business, such as auto, travel, or meals.
- Add back non-recurring expenses, such as one-time legal fees or a major equipment repair that will not repeat.
Dr. Jones’s practice shows $400,000 in net profit. Add back her $250,000 salary, $20,000 in auto expenses, and $15,000 in non-recurring legal fees. Her SDE is $685,000. With a 2× multiple, the practice is worth approximately $1.37 million to a private buyer.
EBITDA for DSO and Private Equity Sales
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It measures the practice’s operating profitability, separate from the owner’s compensation and the practice’s financing. A DSO is buying a platform for growth, not a job for an owner-operator. The selling owner usually stays on under a multi-year employment agreement at a market-rate salary, so the DSO focuses on what the practice earns as a business.
To calculate EBITDA:
- Start with net profit.
- Add back interest, taxes, depreciation, and amortization, which are accounting or financing items rather than operating costs.
- Add back the owner’s compensation above a market-rate replacement salary. The excess is a discretionary add-back.
- Add back other documented, defensible non-recurring or personal expenses.
Dr. Lee’s practice has $500,000 in EBITDA. With a 5× multiple, the practice is worth $2.5 million to a DSO buyer.
Critical warning: Every add-back should be defensible and documented. A buyer’s quality-of-earnings team, which is the group of accountants and analysts a DSO hires to review the financials, will examine each line item. If an add-back cannot be supported with records, it may be removed, and EBITDA can drop. That change can reduce the purchase price. McLerran’s CPA-led analysis aims to address these issues before the deal goes to market.
For a full explanation of valuation methods and how they interact, see McLerran’s article on dental practice valuation methods explained.
Private Buyer vs. DSO: How Buyer Type Changes Valuation
Buyer type can be the strategic core of any valuation exercise. The same practice can carry two very different price tags depending on who sits across the table.
- Private buyer (another dentist): Often uses SDE or a percentage of collections. Multiples are generally lower, typically in the 1.5–3× SDE range, because the buyer is an individual with limited capital who will work in the practice. Deals are usually structured as all cash at closing.
- DSO or private equity buyer: Uses EBITDA. Multiples are generally higher, often 4–6× EBITDA for smaller or less desirable add-on acquisitions, 5–8× for most add-on deals, 9–11× for platform acquisitions, and up to 11–13×+ for larger platforms. These buyers acquire a platform for growth and can create efficiencies across a larger network. Deal structures are often more complex, with a portion of the price paid in equity or as an earnout rather than cash at closing.
The practical impact can be significant. A practice with $685,000 in SDE and $500,000 in EBITDA might be worth about $1.37 million to a private buyer and $2.5 million to a DSO. That difference can exceed $1 million for the same practice. An owner who explores only one path may never see the full range of options.
McLerran & Associates works both transition paths in roughly equal measure and provides a true side-by-side valuation so owners can compare options with more complete information before choosing a direction.

Key Value Drivers That Can Move Your Multiple
Multiples usually reflect the risk and opportunity a buyer sees in the practice. Several common factors tend to influence where a practice lands within any given range.
- Practice size: Larger revenue and patient counts can support higher multiples because they often represent more durable, scalable businesses.
- Profitability: For a general dental practice, a healthy overhead ratio is typically 60–65% of collections. Under 60% is excellent, while above 68% can signal a problem. Higher overhead usually compresses value.
- Growth trend: Consistent year-over-year revenue growth signals opportunity and can support a higher multiple. Flat or declining revenue tends to signal risk.
- Payer mix: Heavy Medicaid or government-program exposure can lower value. Fee-for-service and commercial PPO revenue can raise it, as these streams often carry more predictable and higher margins.
- Patient concentration: When a single patient or small group represents a large share of revenue, buyers may see concentration risk and discount the multiple.
- Facility condition: Modern, well-maintained facilities reduce the capital investment a buyer must make after closing and can support stronger pricing.
- Equipment age and technology: Digital scanners, digital X-rays, and paperless systems can reduce a buyer’s upfront capital needs and signal an operationally current practice.
- Staff stability: Long-tenured hygienists and office managers often represent embedded goodwill, including relationships and reputation, and can increase value.
- Location: Urban and growing suburban markets tend to attract more buyers and can support higher multiples than rural or declining markets.
Once you have a sense of the potential valuation, it helps to understand that the headline price usually differs from what you actually keep. Several deductions sit between the valuation and the cash that reaches your account.
From Valuation to Proceeds: What You Will Actually Walk Away With
Purchase price and net proceeds rarely match. Several common deductions sit between the headline valuation and the cash that reaches the seller’s account.
- Outstanding debt: Equipment loans, lines of credit, and other practice liabilities are typically paid off at closing and reduce net proceeds.
- Transaction costs: Legal fees, accounting fees, and advisory fees reduce the net amount received.
- Taxes: The tax treatment of a dental practice sale can be significant and can vary by deal structure. DSO deals are often structured to capture long-term capital gains treatment on part of the proceeds, which can be lower than ordinary income rates. A qualified tax advisor can provide guidance for your situation.
- Equity and earnout portions: In a DSO deal, up to about 40% of the purchase price may be paid in equity rather than cash at closing. That equity is not liquid at the time of sale.
If a practice sells for $2 million, but the owner carries $300,000 in debt and incurs $100,000 in transaction costs, net proceeds before taxes are $1.6 million. If 30% of the deal is structured as equity, cash at close is closer to $1.12 million. Understanding this gap before signing a letter of intent can help an owner decide whether a deal supports their financial goals.
Why a Professional Valuation Can Be Worth the Investment
A DIY calculation or a free valuation from a broker can serve as a starting point. When a buyer’s quality-of-earnings team reviews every add-back and assumption, a weak valuation often gets renegotiated, and the seller may walk away with less than expected.
Many free valuations function as lead magnets. They often provide back-of-the-napkin numbers designed to generate interest rather than withstand scrutiny. A paid, CPA-led valuation is typically more thorough and documented and is performed by advisors who regularly close practice sales. For more on this distinction, see McLerran’s article on whether a free dental practice valuation is worth it.
In one case, a free valuation pegged a practice at $2.5 million. McLerran valued it at $4.5 million, and it sold for $5.25 million after a competitive process. That outcome reflected diligence-grade work done up front, a structured auction among vetted buyers, and quality-of-earnings support through closing.
McLerran’s track record reflects this approach, with approximately 2,000 successful practice sales, an 85–90% transaction rate (versus an industry norm closer to 35–40%), and an average valuation lift of about 30% compared to what many owners achieve selling on their own.
Conclusion: Simple Math, Complex Strategy
The basic math of dental practice valuation can be straightforward. You can often reach a rough number in about 15 minutes with a calculator and spreadsheet. That number usually serves as a starting point rather than a final answer. The method that produces the most realistic value can depend heavily on who is buying, and a defensible number usually requires professional, CPA-led analysis that holds up when buyers review the details.
- Rules of thumb, such as 60–80% of collections, can serve as starting points rather than full valuations.
- Income-based methods, SDE for private buyers and EBITDA for DSOs, often provide more accurate pictures, and the right one depends on the buyer.
- As shown earlier, the same practice can be worth over $1 million more to a DSO than to a private buyer, so calculating both paths can be valuable.
- A professional valuation is more likely to survive due diligence and reduce the risk of renegotiation at the closing table.

Frequently Asked Questions
What is the typical rule of thumb for valuing a dental practice?
As mentioned earlier, many advisors use a rule of thumb of 60–80% of annual gross revenue (collections), with some citing slightly different ranges. For private-buyer dental practice transactions, SDE multiples commonly range from 1.75× to 2.25×, based on Private Practice Research’s 2026 framework. DSO transactions are often priced on EBITDA multiples of 5×–7× or higher. These figures can be starting points only. They do not fully account for profitability, growth trends, payer mix, or buyer type. Two practices with identical collections can differ by hundreds of thousands of dollars in value based on overhead and operational factors alone.
How do I calculate EBITDA for my dental practice?
Start with the practice’s net profit from its tax return or profit-and-loss statement. Add back interest expense, income taxes, depreciation, and amortization, which are accounting or financing items rather than operating performance. Then add back the owner’s compensation above a market-rate replacement salary, along with any other documented, non-recurring, or personal expenses that ran through the business. The result is EBITDA, which reflects the practice’s operating earnings, separate from how it is financed or how the owner is paid. As noted earlier, every add-back should be documented so it can withstand a buyer’s quality-of-earnings review. A CPA-led analysis can help ensure the add-backs are defensible before the practice goes to market.
Why does a DSO pay more for a dental practice than a private buyer?
A DSO or private equity buyer is acquiring a platform for growth rather than a job. These buyers can create operational efficiencies across a larger network, use centralized administrative infrastructure, and pursue returns on the practice’s earnings at scale. Because they focus on operating profitability instead of an owner-operator income stream, they often apply higher multiples to EBITDA. A private buyer, another dentist, is buying a practice they will work in, with limited capital and no network efficiencies to draw on. Their valuation usually anchors to what the practice pays the person in the chair, which is SDE, and their multiples reflect that more modest investment profile. The same practice can be worth significantly more to a DSO than to a private buyer, so calculating both values before choosing a transition path can be helpful.
What factors most commonly reduce a dental practice’s valuation?
Several factors can push a practice’s value below the midpoint of a typical range. High overhead, generally above 65% of gross revenue, compresses profitability and can reduce value. Heavy reliance on Medicaid or government-program revenue can also lower value because these streams often carry lower margins and more regulatory risk. Patient concentration risk, where a small number of patients account for a large share of revenue, signals fragility to buyers. Aging or outdated equipment increases the capital investment a buyer must make after closing. Flat or declining revenue trends can suggest limited growth opportunity. Facility condition also matters, because a poorly maintained or outdated space tends to attract fewer buyers and lower offers than a comparable practice in a modern, well-equipped facility.
How is a professional dental practice valuation different from a free one?
A professional, CPA-led valuation is built from the ground up using the practice’s actual financial data, including management software reports, tax returns, and profit-and-loss statements. Every discretionary, personal, and non-recurring expense is unpacked and documented. The result is a diligence-grade number that is more likely to hold up when a buyer’s quality-of-earnings team reviews it, which can reduce the risk that the agreed price gets renegotiated at closing. A free valuation typically serves as a lead-generation tool. It often provides a quick estimate that may be inflated to generate interest but lacks the documentation and rigor needed for due diligence. When a weak valuation meets a sophisticated buyer, the seller often loses ground. McLerran’s paid valuation process is designed to reduce that risk, and the firm’s approximately 85–90% transaction rate reflects the impact that diligence-grade work can have.
