What is the cost of a missed lead?
A missed lead costs the expected value of one new customer — typically $200 to $2,500 for service businesses, depending on lifetime value and conversion rate at the missed step. The calculation: (lifetime value of one new customer) × (conversion rate from qualified lead) = expected revenue per qualified lead. If a roofing contractor's average customer is worth $8,000 LTV and converts at 30% from inbound qualified, every missed lead represents $2,400 in expected revenue. Across a year, missing 1 lead per week is ~$125,000 in missed revenue for that contractor. The most common cause of missed leads in service businesses is unanswered inbound calls — research shows 62% of unanswered business calls do not result in a callback. Aira eliminates this miss category by answering every call in 0.4 seconds, qualifying every lead, and routing in real time. See the missed-lead cost calculator.
Missed-lead cost by service business profile
Below are typical missed-lead costs across common service-business profiles. Numbers assume a typical inbound qualification rate (60% qualified) and post-qualification conversion (30%) — adjust to your actual rates for the most accurate calculation.
| Business profile | Typical customer LTV | Expected value per qualified lead | Annual cost of 1 missed lead/wk |
|---|---|---|---|
| Salon / spa | $300-$600 | $90-$180 | $4,700-$9,400 |
| Solo contractor | $500-$2,000 | $150-$600 | $7,800-$31,200 |
| Small law firm | $1,500-$5,000 | $450-$1,500 | $23,400-$78,000 |
| Dental / medical practice | $800-$2,500 | $240-$750 | $12,500-$39,000 |
| Roofing / specialty trade | $5,000-$15,000 | $1,500-$4,500 | $78,000-$234,000 |
Expected value calculation: LTV × 0.30 conversion = expected revenue per qualified lead. Annual cost: expected value × 52 weeks. Adjust the conversion rate to your actual close rate for a personalized number.
Why missed leads are systematically undercounted
Service businesses underestimate missed-lead cost because the missed leads don't appear in any system. A call that rolls to voicemail and isn't returned doesn't generate a CRM record, doesn't trigger a follow-up workflow, and doesn't show up in revenue reports. The miss is invisible — only the captured leads are counted.
The fix is instrumenting the inbound channel. Modern AI receptionists log every inbound call, every qualified outcome, every routed-to-human event, and every booked appointment. The qualified-but-missed bucket — leads that came in but didn't get a fast response — is what AI specifically eliminates. The first month a business runs an AI receptionist on inbound, they typically discover 20-50% more inbound demand than they had recorded under the old system.
