The True ROI of 24/7 AI Call Answering: A Numbers-Only Analysis
Skip the testimonials and case studies. Let’s talk pure math. What does 24/7 AI call answering actually return for a typical service business? We’ll use conservative, verifiable assumptions and show the full calculation.
The Baseline Assumptions (Conservative)
• Monthly inbound calls: 200
• Current answer rate (human only): 75% = 150 answered, 50 missed
• Callers who don’t call back after voicemail: 62% = 31 permanently lost
• Average customer value (new customer): $1,500
• Conversion rate (answered calls → customers): 30%
Monthly lost revenue: 31 × $1,500 × 30% = $13,950
With AI Coverage: The Numbers Shift
• New answer rate: 100% = 200 answered, 0 missed
• Previously missed calls now captured: 50/month
• AI conversion rate (live answer): 30% same as human
• New customers from previously missed calls: 15/month
Additional monthly revenue: 15 × $1,500 = $22,500
