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:

  1. Captured Revenue: Bookings from calls you currently miss
  2. Cost Savings: Reduced staffing and answering service costs
  3. 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

Frequently Asked Questions

Most medical spas see 8x-40x ROI on their AI receptionist investment. The break-even point is typically just 1-2 additional bookings per month.
Multiply your missed/after-hours calls by your booking conversion rate, then by your average appointment value. Example: 50 missed calls × 35% conversion × $300 = $5,250/month in missed revenue.
