How the numbers shift across typical situations for this calculator:
| Scenario | Total ROI | Annualized ROI | Net profit |
|---|---|---|---|
| $500k · $1.5M · 10yr | 200.00% | 11.61% | $1,000,000.00 |
| $300k startup · $800k · 8yr | 166.67% | 13.04% | $500,000.00 |
| $1M acquisition · $3M · 12yr | 200.00% | 9.59% | $2,000,000.00 |
| $700k · $500k · 5yr (struggling) | -28.57% | -6.51% | -$200,000.00 |
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.
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.

Methodology & Review
Return is cumulative net profit (revenue less operating costs and dentist owner pay) against all-in startup investment or acquisition cost. Annualized return is the constant yearly rate over the period. The figure is pre-tax and excludes any sale of the practice — for a true exit ROI, include sale proceeds in net profit.
