Dental Practice Valuation Guide: SDE Multiples, Asset-Based & Market Comparison Methods
Learn the three primary methods for valuing a dental practice with step-by-step examples, benchmarks, and practical tips for buyers and sellers.
Why Dental Practice Valuation Matters
Whether you're buying your first practice, selling after decades of building a patient base, or bringing on a partner, understanding what a dental practice is truly worth is the foundation of every deal. Overpay and you'll struggle under debt; underprice and you leave years of goodwill on the table.
There is no single "right" number — but there are three widely accepted approaches that, used together, give buyers and sellers a defensible range. In this guide we walk through each method with real-world dental benchmarks.
Method 1: Seller's Discretionary Earnings (SDE) Multiples
What Is SDE?
Seller's Discretionary Earnings represent the total financial benefit a single owner-operator extracts from the practice. It starts with net income and adds back:
- Owner's salary and benefits
- Personal expenses run through the business
- One-time or non-recurring expenses
- Interest, depreciation, and amortization
Practice Value = SDE x Multiple
Typical Dental SDE Multiples
| Practice Profile | Revenue Range | SDE Multiple |
|---|---|---|
| Solo GP, rural | $500K–$800K | 1.5x–2.0x |
| Solo GP, suburban | $800K–$1.5M | 2.0x–2.5x |
| Multi-doctor, urban | $1.5M–$3M | 2.5x–3.5x |
| Specialty (ortho, perio) | Varies | 2.0x–4.0x |
Multiples vary based on patient retention, payer mix, location, lease terms, staff stability, and the condition of equipment. A practice with heavy Medicaid revenue or a short remaining lease will command the low end.
Worked Example
Dr. Smith's suburban general practice collects $1.2M per year. After normalizing the financials:
Net Income: $180,000
+ Owner Salary: $220,000
+ Personal Auto Expense: $12,000
+ Depreciation: $35,000
+ One-time legal fees: $8,000
SDE = $455,000
Estimated Value: $455,000 x 2.25 = $1,023,750
Using a 2.25x multiple for a well-run suburban GP practice.
Method 2: Asset-Based Valuation
The asset-based method tallies the fair market value of everything the practice owns — tangible and intangible — and subtracts liabilities. It's particularly useful for practices with significant equipment investments or real estate.
Components of an Asset-Based Valuation
Tangible Assets
- Dental chairs & operatory equipment
- Digital imaging systems (CBCT, panoramic)
- CAD/CAM milling units
- Sterilization equipment
- Office furniture & computers
- Supplies inventory
Intangible Assets
- Patient charts / active patient base
- Practice name & reputation (goodwill)
- Phone number & web presence
- Assembled workforce
- Non-compete agreements
- Favorable lease terms
When Asset-Based Works Best
- New or declining practices where earnings don't reflect asset value.
- Equipment-heavy specialties (oral surgery, orthodontics with iTero scanners, etc.).
- Real estate included in the transaction — value the building separately from the practice.
- Floor value — ensures the buyer isn't paying less than the replacement cost of hard assets.
Method 3: Market Comparison Approach
The market comparison (or "comps") approach values a practice by looking at what similar practices have actually sold for in recent transactions. Think of it as the "Zillow estimate" for dental practices.
Key Comparison Metrics
Price-to-Revenue Ratio
GP practices typically sell for 65%–85% of annual collections. Specialty practices can exceed 100%.
Price-per-Active-Patient
A common shorthand is $350–$600 per active patient (seen within the last 18 months). Quick sanity check, not a primary valuation method.
Price-per-Operatory
Fully equipped operatories in desirable locations are valued at $150K–$250K each, depending on the market.
Where to Find Comparable Sales Data
- Dental practice brokers (AFTCO, Henry Schein Practice Transitions, etc.)
- ADA Health Policy Institute reports
- BizBuySell and DealStream transaction databases
- State dental association surveys
- Your accountant's network of recent transactions
Bringing the Three Methods Together
No single method tells the whole story. A robust dental practice valuation triangulates all three:
SDE Multiple
$1,023,750
Asset-Based
$870,000
Market Comps
$960,000
Defensible Range
$870,000 – $1,023,750
Most deals settle near the midpoint — approximately $950K in this example.
