Where this number comes from
A caller who reaches voicemail is holding a list of other numbers, and the next one that answers usually gets the job. An always-on answer is the difference between a booked job and a lost one.
Reasoning from how callers behave, not a published study

How this calculation works
Three numbers drive the result: 1. Recovered jobs: missed calls × booking rate. These are jobs you'd capture once calls get answered 24/7. 2. Recovered revenue: those jobs × your average ticket. 3. Cost savings: if you're paying a receptionist or answering service, subtract the AI cost from that line item too. Net benefit = recovered revenue + cost savings. Payback period is how many days into the month the recovered revenue covers the AI cost. ROI is monthly net benefit ÷ AI cost. Default assumes 200 calls/month, 35% missed (typical for owner-operated service businesses), 50% booking rate on answered calls, $350 average job, and $150/month AI usage (200 calls × ~3 min avg × $0.25/min).

HVAC shop with 4 techs
300 calls/month, 35% missed, was paying an answering service $400/mo.
AI costs ~$225/mo (less than the answering service it replaced) and recovers ~25 jobs/month at $450 each. Net annual benefit: ~$135K.
Solo plumber, 24/7 emergency
250 calls/month, 40% missed (mostly nights/weekends), no current coverage.
After-hours emergency tickets average $700+. AI handles them, books the morning slot, and texts the on-call tech. Payback in under 2 days.
Owner replacing front-desk hire
Part-time receptionist costs $3,500/mo and doesn't cover nights or weekends.
AI is $300/mo, runs 24/7, and never calls in sick. Direct savings of ~$38K/year before recovered jobs.
