A dental practice valuation estimates what a practice is worth to a buyer today. It matters whether you are selling, buying, bringing in a partner, refinancing, or planning your retirement. The value is not a single formula: a credible valuation looks at the practice from several angles and reconciles them into one supportable number.
Most of a practice’s value is goodwill: the patient base, reputation, staff and systems that keep patients coming back after the owner leaves. Equipment and supplies usually make up a much smaller share.
The Three Main Valuation Methods
| Method | How it works | When it carries the most weight |
|---|---|---|
| Market approach (percentage of collections) | Price is set as a share of annual collections, based on what similar practices have sold for. Rules of thumb commonly fall around 60% to 80% of collections. | Traditional dentist-to-dentist sales of solo practices; a quick reasonableness check for any valuation |
| Income approach (earnings multiple) | Adjusted earnings, owner’s discretionary income (ODI) or adjusted EBITDA, are multiplied by a factor or capitalized at a rate that reflects risk and growth. | Most valuations today; DSO and private equity purchases (often 3x to 8x+ adjusted EBITDA depending on size and growth); lender underwriting |
| Asset approach | The fair market value of equipment, technology, furniture and supplies, less any liabilities assumed. | Practices with low or declining profit; it sets a floor on value |
The percentage-of-collections method is simple, but it ignores profit: two practices that each collect $1.2 million can be worth very different amounts if one keeps 40% of its collections and the other keeps 20%. That is why buyers and lenders rely most on the income approach.
A Worked Example
Consider a hypothetical solo general practice collecting $1,200,000 a year, with owner’s discretionary income of $510,000 and adjusted EBITDA of $300,000 after paying a replacement dentist at market rates.
| Method | Calculation | Indicated value |
|---|---|---|
| Percentage of collections | $1,200,000 × 65% to 75% | $780,000 – $900,000 |
| Earnings multiple | $300,000 adjusted EBITDA × 3.0 to 3.5 | $900,000 – $1,050,000 |
| Asset approach (floor) | Equipment, technology and supplies at fair market value | ≈ $150,000 |
| Reconciled value | Weighted toward the earnings method | $850,000 – $950,000 |
Figures are illustrative only.
What Drives Value Up or Down
| Raises value | Lowers value |
|---|---|
| Steady or growing collections over three years | Declining collections or new-patient counts |
| Strong profit margin and overhead in benchmark ranges | Supplies, lab or payroll well above benchmarks |
| Healthy fee-for-service share; sustainable PPO fees | Heavy dependence on one low-paying PPO or a recent network exit |
| Associates and hygienists producing a large share | Most production tied to the selling dentist |
| Long-tenured, stable staff | High staff turnover or key staff leaving with the seller |
| Assignable lease with long remaining term at fair rent | Short lease, unfavorable terms or a difficult landlord |
| Modern equipment and technology (CBCT, scanners, digital X-ray) | Old equipment that needs replacing soon |
| Desirable location with room to grow | Saturated market or poor visibility and parking |
| Clean, documented financials | Undocumented add-backs or books that do not tie to tax returns |
Information Needed for a Valuation
-
Three years of business tax returns and profit and loss statements, plus the current year to date
-
Production and collections reports by provider and by procedure code
-
Accounts receivable aging and payer mix by carrier
-
Active patient counts and new patients per month
-
Fee schedule and PPO contracts
-
Staff roster with pay, benefits and length of service
-
Office lease, equipment list with ages, and any loans or liens
-
Documentation for every proposed add-back
Purchase Price Allocation Matters Too
The total price is only part of the deal. How it is split among asset classes changes the after-tax result for both sides, so it should be negotiated, not left to the end.
| Asset class | Buyer | Seller |
|---|---|---|
| Goodwill | Amortized over 15 years | Generally long-term capital gain |
| Equipment and furniture | Depreciated over a shorter life, often faster | Depreciation recapture taxed as ordinary income |
| Non-compete agreement | Amortized over 15 years | Ordinary income |
| Supplies | Deducted as used | Ordinary income |
Both parties report the same allocation to the IRS on Form 8594, so it should be agreed in the purchase agreement.
Common Valuation Mistakes
-
Relying on a rule of thumb alone. A percentage of collections says nothing about profit, overhead or risk.
-
Using unadjusted tax-return income. Owner pay, benefits and personal expenses must be normalized, and every add-back documented.
-
Ignoring the doctor-compensation adjustment when the likely buyer is a DSO or investor.
-
Overlooking lease and payer risk. A lease that cannot be assigned or a pending network change can derail a sale.
-
Waiting until the last year. Buyers review three years of results; preparation should start two to three years before a sale.
Know your number before you negotiate. An independent valuation by a CPA who specializes in dental practices shows your practice the way buyers and lenders will see it, so you can set a realistic price, plan for taxes and avoid surprises at the closing table.
