Wondering if an AI receptionist is worth the investment? This guide helps you calculate the exact ROI for your medical spa using real numbers from your practice.
The ROI Formula
AI receptionist ROI comes from three sources:
- Captured Revenue: Bookings from calls you currently miss
- Cost Savings: Reduced staffing and answering service costs
- Efficiency Gains: Staff time freed for higher-value activities
Total ROI = (New Revenue + Cost Savings + Efficiency Value) - AI Cost
Step 1: Calculate Your Missed Call Revenue
Find Your Numbers
Answer these questions about your practice:
- A. Total monthly calls: Check your phone system or estimate (avg medical spa: 200-400)
- B. Calls that go to voicemail: Typically 20-40% of total calls
- C. After-hours calls: Typically 40-65% of total calls
- D. Your booking conversion rate: When you answer, what % book? (avg: 30-40%)
- E. Average appointment value: (avg medical spa: $250-$400)
The Calculation
Monthly Missed Revenue = (B + C) × D × E
Example calculation:
- Total calls: 300/month
- Voicemail calls: 60 (20%)
- After-hours calls: 150 (50%)
- Total missed opportunities: 210 calls
- Conversion rate if answered: 35%
- Average appointment value: $300
Missed revenue: 210 × 35% × $300 = $22,050/month
With AI: Capture 80%+ of These
AI receptionist answer rate: 100%
AI booking conversion: 70-85% (immediate booking vs callback)
Recovered revenue: $22,050 × 80% = $17,640/month
Step 2: Calculate Cost Savings
Current Front Desk Costs
| Cost Category | Your Current Cost |
|---|---|
| Receptionist salary | $____/year |
| Benefits (health, PTO, etc.) | $____/year |
| Training costs | $____/year |
| Turnover/hiring costs | $____/year |
| Answering service fees | $____/year |
| Overtime for coverage | $____/year |
Industry Benchmarks
- Full-time receptionist: $35,000-$50,000/year salary
- Benefits: $8,000-$15,000/year
- Training: $2,000-$5,000/year
- Turnover (60% annual rate): $5,000-$10,000/year
- Answering service: $3,000-$12,000/year
- Total: $53,000-$92,000/year
AI Doesn't Replace—It Augments
Most practices keep their receptionist for in-person tasks while AI handles:
- After-hours calls (100%)
- Overflow during busy periods
- Routine scheduling calls
Typical savings: Eliminate answering service + reduce overtime + hire fewer staff as you grow
Conservative annual savings: $5,000-$20,000
Step 3: Calculate Efficiency Gains
When AI handles routine calls, your staff can focus on revenue-generating activities:
Time Freed Per Day
- Average call length: 4 minutes
- Calls AI can handle: 20-30/day
- Time saved: 80-120 minutes/day = 1.5-2 hours
Value of That Time
Instead of answering phones, staff can:
- Provide better in-person patient experience (increases retention)
- Upsell treatments and products (increases revenue per visit)
- Handle complex patient needs (improves satisfaction)
- Follow up with leads (improves conversion)
Conservative value: $500-$2,000/month in additional revenue from freed time
Step 4: Calculate Total ROI
Sample ROI Calculation
| Category | Monthly Value | Annual Value |
|---|---|---|
| Recovered missed revenue | $17,640 | $211,680 |
| Cost savings | $1,000 | $12,000 |
| Efficiency gains | $1,000 | $12,000 |
| Total Benefit | $19,640 | $235,680 |
| Eva AI Cost | $499 | $5,988 |
| Net ROI | $19,141 | $229,692 |
ROI Multiple: 39x annual investment
Conservative ROI Estimate
Even with conservative assumptions:
- Only 10 additional bookings/month from AI
- $250 average appointment value
- $299/month AI cost
Conservative monthly ROI: $2,500 revenue - $299 cost = $2,201 net
ROI Multiple: 8x
Break-Even Analysis
How many additional bookings does AI need to pay for itself?
- Eva AI cost: $299-$499/month
- Average appointment value: $300
- Break-even: 1-2 additional bookings per month
Most practices see 10-50 additional bookings monthly, making ROI nearly immediate.
How to Track Your ROI
Once you implement AI, track these metrics:
- After-hours bookings: Should jump from ~0 to 20-50/month
- Total bookings: Compare month-over-month
- Call answer rate: Should approach 100%
- Booking conversion rate: Should increase 20-40%
- No-show rate: Should decrease with automated reminders
- Staff satisfaction: Less phone stress, more patient focus
