How This Calculator Works
Enter the all-in investment (acquisition or build-out + equipment + working capital) and cumulative net profit across the years (revenue less operating costs less owner pay). The calculator reports total ROI, net profit, and the annualized rate.
The Formula
Return on Investment
V_start = amount invested, V_end = amount returned; annualized ROI = (V_end / V_start)^(1/n) − 1
Worked Example
A $500,000 dental practice investment producing $1,500,000 of cumulative net profit over 10 years posts a 200% total ROI — about 11.6% annualized. Successful dental practices commonly clear 10% to 20% annualized ROI on the investment, separate from the dentist's owner pay (which typically runs $150k to $400k+). Selling the practice for 60% to 90% of trailing revenue at exit adds materially to total return.
Key Insight
Dental practice ROI splits into two components: operating profit during ownership (10% to 20% annualized typical) and sale proceeds at exit (60% to 90% of trailing annual revenue typical for solo practices). Many dentists treat the practice as a job rather than an investment and miss the exit value calculation — yet the sale proceeds often equal 5 to 10 years of operating profit compressed into one transaction. Practices acquired with the exit in mind tend to outperform those run purely for current income.

ACQUISITION ECONOMICS.
Practice purchase price typically 60-80% of annual collections. $1M revenue = $600-$800K.
Hard assets (equipment, supplies): 15-25% of price.
Goodwill: 75-85% of price.
FINANCING. Dental practice loans up to 100% LTV via specialty lenders (Bank of America Practice Solutions, Live Oak, etc.). 10-year amortization typical.
Buyer doctor takes over substantially seamlessly — patients largely retained.
Specialty practices, DSOs, scaling, valuation
SPECIALTY PRACTICES.
Orthodontics. Substantial $1.5M-$5M revenue. Higher margins 35-45% net.
Periodontics. $1M-$3M. Substantial implant revenue.
Endodontics. $800K-$2M. Substantial procedural focus.
Pediatric. $900K-$2.5M.
Oral surgery. $1M-$3M+. Substantial.
Higher specialty revenue partially offset by higher equipment + specialty staff costs.
DSO MODEL (Dental Support Organization).
Corporate ownership of practice (Heartland, Pacific, Aspen, MB2). Substantial 25-30% U.S. practices DSO 2024.
Dentists become employees or partners.
Substantial benefits: business management offload, group purchasing, marketing scale.
Substantial loss: clinical autonomy, brand identity.
PE investment substantial driver — multiple valuations 6-12× EBITDA.
SCALING.
Solo → group practice (multiple associates). Substantial growth path.
Multi-location. Substantial management complexity.
DSO acquisition. Substantial exit option — premium valuations.
VALUATION.
Solo GP: 60-80% annual collections (~1× annual revenue typical).
Group practice: 70-90% collections.
Specialty (perio, endo, ortho): 75-95% collections.
DSO acquisition: 6-12× EBITDA, substantial premium.
ROI CALCULATION example. Purchase $800K. Annual revenue $1.1M. Owner-dentist comp $250K. Net practice profit $130K. ROI to owner = ($250K + $130K) / $800K = 47.5%.
Substantial — includes owner labor.
Pure financial ROI (excluding owner labor): $130K / $800K = 16%. Substantial vs S&P 500 ~10% historical.

Owner-dentist compensation substantial — pure financial ROI excludes this. Practice loans up to 100% LTV from specialty lenders. DSO (~25-30% U.S. practices) substantial alternative ownership model. ADA Health Policy Institute + Henry Schein practice surveys for benchmarks.
Frequently Asked Questions
What goes into all-in investment?
For new practices: build-out ($150k to $400k), equipment ($150k to $400k including chairs, X-ray, sterilization), first-year operating capital, working capital. For acquisitions: purchase price (typically 60% to 80% of trailing annual revenue for solo practices, higher for groups).
What's a typical dental practice ROI?
Operating ROI on the investment: 10% to 20% annualized for established practices. Including sale proceeds at exit: total return often equivalent to 15% to 25% annualized. Specialty practices (orthodontics, oral surgery, endodontics) often higher operating margins than general dentistry.
What's owner pay versus net profit?
Owner pay (the dentist's salary as practitioner) is an expense — typical $150k to $400k for general dentistry, higher for specialty. Net profit is what remains after owner pay — the actual return on the investment, separate from the dentist's labor compensation.
What about practice valuation at sale?
Solo general practices typically sell at 60% to 80% of trailing 12-month revenue. Specialty practices at 70% to 100%+. Multi-practitioner groups and DSO-attractive practices at higher multiples. Add expected sale proceeds to net profit for total exit return.
Should I buy or build?
Buying captures an existing patient base immediately; building requires marketing-driven growth from zero. Buy works best for mid-career dentists wanting cash flow from day one; build works for entrepreneurial dentists comfortable with 2- to 3-year ramp-up to profitability.
When is this calculator unreliable?
Less reliable when owner-doctor compensation not allocated (treats as profit instead of labor — substantially inflates ROI), when DSO (Dental Support Organization) corporate practice has different structure than independent, when insurance vs cash-pay mix affects collections (in-network rates substantially below billed), when deferred equipment upgrades pending (impacts buyer ROI), or when goodwill vs hard asset allocation affects tax treatment (Section 197 amortization vs depreciation).

Methodology & Review
Dental office ROI = (annual net income / total practice investment) × 100%. Typical dental practice acquisition: $400K-$1.5M (1-2× annual revenue). Operating margins 30-45% (gross), 18-28% net to owner-dentist. Solo GP practice annual revenue $700K-$1.2M typical; specialty $1M-$3M+. Owner-doctor compensation often 25-35% revenue. RELIABILITY: Reliable for documented practice P&L + acquisition cost. Less reliable when (a) owner-doctor compensation not allocated (treats as profit instead of labor); (b) DSO (Dental Support Organization) corporate practices have different structure; (c) insurance vs cash-pay mix affects collections; (d) deferred maintenance / equipment upgrades pending; (e) goodwill vs hard asset allocation affects tax treatment.
