**Input Fields (example):**

**Implementation Costs:**$197 (one-time setup fee)**Ongoing Maintenance Costs:**$197/month = $2,364/year**Expected Benefit from Increased Customer Retention:**We’ll assume an average increase in revenue based on customer retention.**Expected Benefit from Sales Growth:**We’ll assume an average increase in revenue based on sales growth.

**Assumptions:**

- Average annual revenue for a dentist in the USA: $400,000 (source: ADA)
- Expected increase in revenue from customer retention: 5%
- Expected increase in revenue from sales growth: 3%

Using these assumptions, we can calculate:

**Expected Benefit from Increased Customer Retention:**5% of $400,000 = $20,000/year**Expected Benefit from Sales Growth:**3% of $400,000 = $12,000/year

Now we can calculate the ROI:

**Total Annual Benefit:** $20,000 + $12,000 = $32,000 **Total Annual Cost:** $2,364 (maintenance) + $197 (setup, averaged over one year) ≈ $2,561

**ROI Calculation:** ROI=Total Annual Benefit−Total Annual CostTotal Annual Cost×100\text{ROI} = \frac{\text{Total Annual Benefit} – \text{Total Annual Cost}}{\text{Total Annual Cost}} \times 100ROI=Total Annual CostTotal Annual Benefit−Total Annual Cost×100

Substituting the values: ROI=32000−25612561×100≈1149.39%\text{ROI} = \frac{32000 – 2561}{2561} \times 100 \approx 1149.39\%ROI=256132000−2561×100≈1149.39%

This high ROI suggests that implementing an AI customer service system could be very beneficial for a dental practice.
