A dental practice is valued using one or both of two standard methods. The collections method multiplies annual collections (total revenue) by a multiple. This calculator uses 0.60 to 0.80 of collections for a flat practice, 0.75 to 0.95 for a growing one and 0.45 to 0.60 for a declining one. The EBITDA method multiplies operating profit by a multiple; the calculator's range is printed under the result and rises for growing practices.
Most dental practice valuations use both methods and average them. Switch the growth trend between flat and growing in the calculator to see how much the multiple moves for your own numbers. The actual multiple depends on patient retention, payer mix, lease terms, staff stability, and buyer motivation. Use this calculator to benchmark your practice value, then hire a CPA and broker for a real appraisal.
How practice valuation works
Dental practices are valued using two common methods, often combined:
Method 1: Collections Multiple
Value = Annual Collections x 0.60 to 1.0 (depending on growth and profitability)
Method 2: EBITDA Multiple
Value = Annual EBITDA x 2.5 to 4.5 (depending on growth and stability)
Final estimate is the average or range of both methods, adjusted for growth trend and market conditions.
This tool uses these common multiples as assumptions:
- Collections multiple: 0.60-0.80 for flat or declining practices, 0.75-0.95 for growing practices
- EBITDA multiple: 1.5-2.5 for declining, 2.5-3.5 for flat, 3.5-4.5 for growing practices
These are standard in dental practice sales. Individual transactions vary based on patient retention, payer mix, location, and buyer motivation.
A worked example
A 12-year-old general dental practice with 3 operatories and flat growth:
- Annual collections: $900,000
- EBITDA: $200,000 (22% margin)
- Growth: flat (no year-over-year growth)
Valuation using both methods:
- Collections method: $900,000 x 0.70 (flat practice midpoint) = $630,000
- EBITDA method: $200,000 x 3.0 (flat practice midpoint) = $600,000
- Average: ($630,000 + $600,000) / 2 = $615,000
- Range: $550,000 to $700,000 depending on buyer and market
The practice would likely sell for $580,000-$650,000 in a normal market. If it were growing, the range would be $700,000-$850,000.
What is not included in this estimate
This calculator gives a ballpark range only. A real valuation for a sale or acquisition is much more detailed and requires professional help:
- Patient retention: A buyer pays a premium if 85%+ of patients stay through transition. Lower retention drops value by 10-20%.
- Payer mix: Practices with mostly insurance pay more predictably but often have lower margins. Cash-heavy practices are worth more per dollar of revenue.
- Goodwill: A buyer pays extra if the seller will introduce patients and stay involved for 1-2 years post-sale. Absentee sellers get less.
- Location and lease: Favorable lease terms and prime location add value. A poor location or unfavorable lease reduces it.
- Staff stability: Turnover or key staff leaving right before sale reduces value. Stable, trained staff is a major asset.
- Debt and liabilities: Equipment loans, office debt and lawsuits are subtracted from the valuation.
For a real sale, hire a CPA who specializes in dental practice valuation and a dental practice broker. A broker charges a commission on the sale; for most owners that is worth it for the buyer matching and the negotiation, but run this calculator first so you walk in knowing your range.
Improving practice valuation before sale
- Grow collections: Increase new patient flow by 10-20% in the year before sale. A growing practice sells for 20-40% more.
- Improve margins: Cut overhead, optimize staffing and reduce lab costs. A 25% EBITDA margin instead of 20% adds $100k+ to value.
- Increase patient retention: Show the buyer that 85%+ of patients stay. This is one of the biggest value multipliers.
- Systemize everything: Document your workflow, staff roles and patient follow-up systems. A turnkey practice is worth more.
- Stay in the practice: A seller who stays 1-2 years post-transition can add 10-20% to the sale price. Buyers value continuity.

Questions people ask
How is a dental practice valued by a broker?
A dental practice broker uses collections multiples, EBITDA multiples and adds adjustments for patient retention, payer mix, location, lease favorability, staff stability, and seller involvement. A real appraisal also factors in goodwill (relationship capital with patients), any debt, and comparable recent sales in your market. A broker's valuation is more precise than this calculator and comes with a commission on the sale, so use the calculator first to learn which levers move your number.
Is this valuation accurate for a real sale?
No. This is a benchmarking tool, not a formal appraisal. A real sale valuation done by a CPA or broker will consider patient retention, payer mix, location, lease terms, staff stability and many other factors. Use this to ballpark value and identify gaps, then hire professionals for a real number.
What is a good EBITDA margin for a dental practice?
20-25% is typical for a general practice. Specialty practices (ortho, implants) often run 25-35%. Solo practices may run lower due to owner withdrawal. A practice under 15% margin has cost or operational issues.
How much does growth boost a dental practice valuation?
Significantly. A growing practice sells for more than a flat practice with the same revenue because a buyer is paying for next year's collections, not last year's. Buyers see growth as de-risking. A declining practice sells for 30-50% less. Before selling, give yourself a year or two of documented growth; the calculator shows what the growing multiple does to your estimate.
Should I stay after selling?
If you want to maximize price, yes. Many buyers offer a seller earn-out or transition fee if you stay 1-2 years to introduce patients and train staff. This can add $50,000-150,000 to the total deal.
When is the right time to sell?
When your practice is stable and growing, your margins are strong, and you have documentation of patient retention and processes. Most sellers do best after 10-20 years of operations when buyer risk is lowest and valuation is highest.
How much does growth boost valuation?
Significantly. A growing practice (10%+ year-over-year growth) sells for 40-60% more than a flat practice with the same revenue. Buyers see growth as de-risking. A declining practice sells for 30-50% less.
