How Much Money Are You Losing to Missed Calls?
The average local service business misses 35–40% of inbound calls. Most owners know it's a problem. Few know what it actually costs. Using published research on local-business call handling and the math below, here's how to put a dollar figure on the gap.
The miss rate is higher than you think
Before installing their AI receptionist, our customers averaged a **38% miss rate** on inbound calls. That means nearly 4 in 10 calls went to voicemail — or rang out.
When was that? Most often:
• During a job (hands dirty, can't pick up)
• During appointments (dentist, medspa, salon)
• During peak volume (3–6 PM, Monday mornings)
• After hours (6 PM–8 AM, weekends)
Voicemail conversion rate: approximately 20–25% of voicemail callers leave a message. Of those, about 40% reach a human before booking elsewhere.
What a missed call actually costs by industry
These are median ticket values based on our customer data, not estimates:
| Industry / call type | Avg ticket value | Cost per missed call (38% × 70% close) |
|---|---|---|
| Plumbing (emergency) | $2,500 | $950 |
| Plumbing (service call) | $380 | $152 |
| HVAC (installation) | $8,200 | $3,116 |
| HVAC (service call) | $290 | $110 |
| Dental (new patient) | $1,800/yr LTV | $684 |
| Auto repair | $620 | $236 |
| Law firm (consult) | $3,500+ | $1,330+ |
| Hair salon (new client) | $85/visit | $32 |
The math for a plumbing business
Take a 2-truck plumbing operation getting 60 calls per month:
• **60 calls/mo × 38% miss rate = 23 missed calls/month**
• Of those 23, ~17 were booking calls (70% of total volume)
• Average ticket: $600 (blended service + emergency)
• Conversion rate if answered: 65%
**17 missed booking calls × 65% close rate × $600 = $6,630/month in lost revenue**
At $99/month, the AI receptionist has a **67× ROI** on prevented missed calls alone — and that's before counting reviews, repeat business, or referrals from satisfied customers who got through.
The Saturday 9 AM problem
The highest-value missed calls happen Saturday mornings. Customers who woke up with an emergency (burst pipe, A/C dead in summer, car won't start before a trip) are highly motivated buyers.
Most service businesses answer Saturday morning at 60–70% capacity. The ones at 100% capacity — because their AI answers everything — win a disproportionate share of weekend revenue.
Businesses that answer every weekend call — instead of the typical 60–70% — win a disproportionate share of that high-intent revenue.
Calculate your own number
**Step 1:** Estimate your monthly call volume (check your phone's call log for the last 30 days).
**Step 2:** Estimate your miss rate. If you're typically on jobs 4–6 hours/day, assume 35–45%.
**Step 3:** Multiply missed calls × average ticket × close rate.
**Example:** 80 calls/mo × 38% miss = 30 missed × $800 average × 60% close = **$14,400/month**.
That's the upper bound of recoverable revenue. In practice, half of missed callers call a competitor. The realistic capture is 50–60% of that number — still $7,200–8,640/month.
Vs. $99/mo to fix it.
