Key Takeaways
-
The collections percentage range of 65–85% is only a starting screen for doctor-to-doctor deals. Normalized profitability, measured as EBITDA or SDE, can be some of the main factors that drive final value.
-
Two practices with the same collections can sell for very different prices once overhead, payer mix, owner production, and hygiene revenue are reviewed.
-
DSO and private-equity buyers typically value practices on a multiple of EBITDA instead of a percentage of collections, which can create a different and often higher valuation path.
-
The collections rule of thumb often breaks down for high-overhead, owner-dependent, declining, or Medicaid-heavy practices because it treats every revenue dollar as equally valuable.

How The Collections Rule Of Thumb Really Works
A dental practice sold in a doctor-to-doctor transaction is often screened at roughly 65% to 85% of trailing annual gross collections, based on dental-specific valuation benchmarks. This range works as a quick screen rather than a final number. The final price usually reflects profitability, measured as EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) or SDE (Seller’s Discretionary Earnings), and the specific fundamentals of the practice.
The range stays wide because practices vary widely. A practice near the top of the band often has strong hygiene revenue, a favorable payer mix, associate-driven production, and consistent growth. A practice near the bottom often carries risk factors such as high overhead, owner-dependent production, or declining collections. The bottom of the range tends to apply to practices with high overhead, owner-dependent production, deferred technology, declining collections, or rural locations with thin buyer pools, while the top tends to apply to practices with associate-driven production, modern digital workflow, growing patient bases, and metropolitan locations.
The collections percentage also fits most cleanly with doctor-to-doctor (private-buyer) transactions. DSO and private-equity buyers usually apply a different framework that focuses on a multiple of EBITDA. Collections sits at the top line and does not show what the practice actually keeps after expenses. The table below shows how the two buyer types differ on method, range, and the main driver behind each number.

How Collections And EBITDA Connect In A Real Valuation
Collections set the revenue base, and EBITDA or SDE set the earnings base that usually drives the price. Together they form the bridge between a quick rule of thumb and a defensible valuation for a $1.2 million-collections practice.
Step 1: Use The Collections-Based Screen. At 70% of collections, the rule of thumb suggests a value of $840,000 for a $1.2 million practice. That figure is often the number a broker or DSO representative quotes during an early conversation.
Step 2: Normalize The Income Statement. A diligence-grade valuation goes deeper than collections. It reviews the profit-and-loss statement to find true profitability. This process adds back expenses that are discretionary, personal, or non-recurring and that would not continue for a new owner. Common add-backs in a dental practice include owner compensation above a fair-market replacement salary, personal vehicle expenses, continuing education with a personal travel component, one-time equipment purchases, and discretionary retirement contributions above the staff plan match. A clean add-back schedule lists each expense, the amount, the year, the reason for the adjustment, and supporting documentation.
Step 3: Select The Right Earnings Metric. SDE (Seller’s Discretionary Earnings) adds back the owner’s full compensation and usually applies when the buyer will be another owner-operator dentist. EBITDA normalizes owner compensation to a market-rate replacement salary, because a DSO or private-equity buyer must pay an associate to cover that production after the seller exits. A dental practice might show $400,000 in SDE but only $200,000 in normalized EBITDA. That gap reflects the value of the owner’s own labor and often creates confusion in dental valuations.
Step 4: Apply The Appropriate Valuation Method. A doctor-to-doctor deal typically uses a percentage of revenue or a multiple of SDE. A DSO or private-equity deal usually uses a multiple of EBITDA. The same $1 million practice can be valued at $700,000 using a 70% collections multiple or $850,000 using an EBITDA multiple. That $150,000 difference comes from method, not from a change in the practice.
Step 5: Focus On The EBITDA Number That Survives Diligence. When a buyer’s diligence team reviews a deal, they test every add-back. If a seller claims $1.1 million of adjusted EBITDA but can only document $800,000, the $300,000 gap becomes $1.8 million of enterprise value at a 6x multiple. The practice did not change, but the unsupported number did. A collections-based screen that never ties back to normalized profitability rarely survives that review.
For a $1.2 million-collections practice, the collections screen and the EBITDA-validated value can differ by hundreds of thousands of dollars. Overhead, owner production, and buyer type usually drive that gap. The EBITDA-based figure is the one that tends to hold through diligence and shape what the seller receives at closing.

Factors That Move A Practice Above Or Below The Collections Range
Several practice fundamentals can move value toward the top or bottom of the collections range, and sometimes outside it. Each factor works through a specific mechanism that a buyer’s diligence team can usually test.
-
Payer mix. Fee-for-service and PPO revenue often support higher valuations. Government payer (Medicaid plus state programs) above 35% of collections can reduce the multiple by 10% to 30% and limit the buyer pool. Lower reimbursement rates compress margin, and many institutional buyers exclude Medicaid-heavy practices from their criteria.
-
Hygiene revenue as a share of production. Hygiene above 30% of collections with strong recall often supports top-of-band pricing. Hygiene revenue tends to be recurring and provider-independent, which usually aligns with what buyers want to underwrite.
-
Owner production. Owner-doctor production above 50% of collections can reduce the EBITDA multiple and often leads to heavier earnouts and longer post-close employment commitments. A buyer generally wants to purchase a practice that functions beyond the current owner’s chair time.
-
Overhead and staffing structure. National median dental practice overhead often runs around 55% to 65% of collections, with high performers closer to the mid-50s. Practices in that high-performing range tend to command premium pricing, while practices above 70% overhead usually see compressed value.
-
Active patient count and new-patient flow. Practices with hygiene recall rates above 85%, fee-for-service payer mix above 60%, associate coverage, and active DSO interest often reach 78% to 85% of collections. Active patient count reinforces that pattern. Practices above 1,500 active patients with steady new-patient flow usually support above-average pricing, and the strongest premium multiples often go to practices exceeding 1,800–2,000 active patients with documented growth.
-
Equipment and facility condition. Modern digital dentistry, CBCT, and well-maintained operatories reduce the capital spending a buyer must plan for after closing. The concept of “Tech Debt,” meaning the cost to modernize an analog practice after closing, often reduces sale price because the buyer pool shrinks and competitive bidding weakens.
-
Revenue durability. A practice that grew from $950,000 to $1.2 million over 3 years usually looks very different from one that declined from $1.4 million to $1.2 million, even though both collected $1.2 million last year. Buyers often read a declining trend as a forecast and adjust pricing accordingly.
Specialty also shapes buyer demand and valuation. Oral and maxillofacial surgery often commands the highest multiples and is consolidating quickly. Orthodontics and pediatric dentistry tend to draw strong institutional interest. General dentistry still earns aggressive, near-all-time-high valuations in many markets. Lighter-demand specialties usually sit at the lower end of the range. McLerran & Associates tracks these specialty-by-specialty dynamics rather than treating every practice the same.

When The Collections Rule Of Thumb Breaks Down
The collections percentage can work as a first screen for small, stable general practices with typical overhead and a predictable patient mix. It often breaks down, sometimes sharply, in several specific situations.
High-overhead practices. Consider two practices that each collect $1 million. One runs 60% overhead and produces $400,000 in operating profit. The other runs 75% overhead and produces $250,000 in operating profit. Under a 75% of collections multiplier, both would be valued at $750,000 despite very different underlying economics. A buyer focused on profit, and a lender focused on repayment, will usually view those practices very differently.
Owner-dependent practices. When the owner produces most of the revenue and holds key patient relationships personally, the collections figure often overstates transferable value. When the owner performs 70% or more of the dentistry, the buyer is effectively purchasing a job that may disappear when the owner leaves.
Declining or volatile collections. A practice with 2 years of revenue decline going into a transaction usually faces tougher questions in diligence. Applying a collections percentage to a shrinking top line often produces a number that does not match the practice’s forward trajectory.
Heavy Medicaid or capitation exposure. Low reimbursement rates compress margin. A collections-based multiplier treats a Medicaid dollar and a fee-for-service dollar the same, even though buyers often value them differently.
Inflated or non-recurring collections. A seller might present $1.1 million in “collections” when $950,000 was actually received and $150,000 remains in accounts receivable. That $150,000 can be valued at 70%, adding $105,000 to the asking price for revenue the buyer may spend months collecting, if it is collected at all.

Buyer And Seller Perspectives On Anchoring
A collections-based offer often serves as an anchor that sets the frame of the negotiation before the seller has established their own number. Practices taken to market through a structured multiple-buyer solicitation process often receive final sale values above initial unsolicited offers.
A seller who speaks with only one buyer usually has no competitive tension to move the price higher. The buyer understands this dynamic. The collections percentage they quote typically reflects their acquisition model and risk tolerance rather than full market value.
A more balanced approach starts with an independent, diligence-grade valuation and a plan to create competition among multiple vetted buyers. Many free valuations function as lead magnets and produce quick estimates that may not hold up under scrutiny. Weak valuations often get re-traded when a buyer’s diligence team reviews the details.
McLerran & Associates works solely on the sell-side and represents the practice owner, not the buyer. The firm typically runs a structured, auction-like process among a vetted pool of qualified buyers, often generating around 10 offers. That structure usually helps owners negotiate from a position of strength instead of from a single anchor number set by the other side of the table.
What To Do Next: Timing And Contents Of A Real Valuation
A diligence-grade valuation goes far beyond a calculator estimate or a quick broker opinion. It usually involves remote access to practice management software and cross-referencing production and collections reports against financials. From there, every discretionary and non-recurring expense is reviewed to arrive at true profitability. Value is then calculated by the method that fits the likely path: a percentage of revenue or multiple of net cash flow for doctor-to-doctor deals, and a multiple of EBITDA for DSO and private-equity deals.
McLerran & Associates has evaluated more than 10,000 dental practices and typically delivers a side-by-side valuation that shows worth in both the private-buyer and DSO markets. If an owner is not ready to sell, the firm can update the valuation a year later at no additional cost, which gives owners time to prepare without pressure to transact.
The right time to request a detailed dental practice valuation often comes 1 to 3 years before a planned transition, so there is time to act on the findings. A change in normalized EBITDA can translate into hundreds of thousands of dollars in deal value at an EBITDA multiple, which makes the preparation period a potentially high-return investment for many practice owners.

Frequently Asked Questions
How Do You Value a Dental Practice Based on Collections?
The 65–85% of collections range works as a quick screen for doctor-to-doctor deals, as described above. To use it safely, many owners compare the percentage-based figure to a valuation built on normalized EBITDA or SDE. That comparison often highlights whether overhead, payer mix, or owner production patterns support the percentage or call for an adjustment before relying on it.
Does the Collections Percentage or EBITDA Matter More?
EBITDA usually matters more for the final price because it reflects what the practice earns after normalizing owner compensation and removing discretionary and non-recurring expenses. Collections provides a top-line screen and a quick reference point. EBITDA shows the earnings that a buyer’s diligence team and lenders typically underwrite, so it often becomes the figure that shapes the actual offer.
Why Is the Collections Range So Wide?
The 65% to 85% range reflects wide variation in practice fundamentals. Factors such as hygiene revenue, payer mix, associate coverage, equipment, growth trend, and location can move a practice toward either end of the band. The same collections figure can therefore support very different valuations once those fundamentals are reviewed in detail.
When Does the Collections Rule of Thumb Fail?
The collections rule of thumb often produces misleading results for high-overhead practices, owner-dependent practices, practices with declining or volatile collections, Medicaid-heavy practices, and practices with inflated or one-time revenue. In these situations, normalized earnings usually give a clearer picture of value than a simple percentage of collections.
Are DSO Deals Valued the Same Way as Doctor-to-Doctor Deals?
DSO and private-equity deals are generally valued on a multiple of EBITDA rather than a percentage of collections. A private buyer who will sit in the chair often underwrites SDE, which includes the full value of the owner’s clinical production. A DSO buyer typically underwrites EBITDA after subtracting a market-rate associate salary to replace that production. This difference can create very different offer structures for the same practice.
What Does a Diligence-Grade Valuation Include?
A diligence-grade valuation usually includes remote access to practice management software, cross-checking production and collections reports against tax returns and financial statements, and a line-by-line review of discretionary, personal, and non-recurring expenses. It then calculates value using a percentage of revenue or multiple of SDE for doctor-to-doctor deals, and a multiple of EBITDA for DSO and private-equity deals. The result is a number designed to hold up when a buyer’s diligence team reviews it.
Conclusion
The collections rule of thumb can serve as a helpful starting screen, but it does not stand on its own. The percentage a seller hears usually gains meaning only after it is connected to normalized profitability, such as EBITDA or SDE, and tested against the practice’s fundamentals, including payer mix, hygiene revenue, owner production, overhead, patient count, equipment condition, and revenue trend.
A single collections figure can translate into valuations that differ by hundreds of thousands of dollars once buyer type, overhead structure, and documentation quality enter the picture. A diligence-grade valuation that focuses on normalized earnings and real market data often captures that range more accurately than a simple percentage.
The most practical next steps often include reviewing current financials, clarifying transition goals, and learning how both doctor-to-doctor and DSO paths would view the same practice. From there, a formal valuation can help anchor expectations before any percentage-based offer appears. Market conditions and buyer appetite change over time, so periodic reassessment can be a valuable habit for owners who are within a few years of a transition.
