The ROI Formula

Based on our analysis, here's the formula to predict your ROI:

Annual Benefit = A + B + C + D + E

A: Recovered Missed Calls

• Weekly calls × Missed call rate × Conversion rate × Appointment value × 52

B: Reduced No-Shows

• Weekly appointments × No-show rate × Reduction (typically 60%) × Appointment value × 52

C: Staff Savings

• Current receptionist cost - AI cost

D: After-Hours Bookings

• After-hours calls (typically 30% of total) × Conversion rate × Appointment value × 52

E: Time Savings

• Hours saved per week × Your hourly rate × 52

ROI = (Annual Benefit - AI Cost) / AI Cost × 100

Real Examples Using the Formula

Example 1: Dental Practice

Inputs:

• Weekly calls: 100
• Missed call rate: 25%
• Conversion rate: 30%
• Appointment value: $200
• Weekly appointments: 80
• No-show rate: 20%
• Current receptionist cost: $3,500/month
• AI cost: $299/month

Calculation:

A: Recovered Missed Calls 100 × 0.25 × 0.30 × $200 × 52 = $78,000

B: Reduced No-Shows 80 × 0.20 × 0.60 × $200 × 52 = $99,840

C: Staff Savings ($3,500 - $299) × 12 = $38,412

D: After-Hours Bookings 30 × 0.30 × $200 × 52 = $93,600

E: Time Savings 5 hours × $100 × 52 = $26,000

Total Benefit: $335,852 AI Cost: $3,588 ROI: 9,260%

Example 2: Small Salon (Low ROI Scenario)

Inputs:

• Weekly calls: 40
• Missed call rate: 10%
• Conversion rate: 40%
• Appointment value: $65
• Weekly appointments: 35
• No-show rate: 8%
• Current receptionist cost: $0 (owner answers)
• AI cost: $149/month

Calculation:

A: Recovered Missed Calls 40 × 0.10 × 0.40 × $65 × 52 = $5,408

B: Reduced No-Shows 35 × 0.08 × 0.60 × $65 × 52 = $5,678

C: Staff Savings $0

D: After-Hours Bookings 12 × 0.40 × $65 × 52 = $16,224

E: Time Savings 3 hours × $50 × 52 = $7,800

Total Benefit: $35,110 AI Cost: $1,788 ROI: 1,864%

Note: Still great ROI, but not life-changing like high-volume businesses.
