Missed calls don't show up on any invoice, which is exactly why they're so dangerous. You never see the job you didn't win. Let's put a real dollar figure on it, because once you do, the problem is impossible to ignore.
Start With the Miss Rate
Across the home services trades, contractors miss 20% to 30% of inbound calls. They're on a job, it's after hours, or two calls come in at once. And here's the part that turns a missed call into lost revenue. The majority of callers who hit voicemail never call back. They call the next company in the search results.
The Formula
To estimate what missed calls cost you per year:
Annual lost revenue =
Monthly calls
× Miss rate
× Booking rate (of answered calls)
× Average job value
× 12
It's a conservative formula. It only counts the missed callers you would have booked at your normal rate.
A Worked Example
Take a mid-sized HVAC company:
- 400 inbound calls/month
- 25% missed, which is 100 missed calls
- Of calls you answer, you book 40%, so apply that to the missed ones: 40 lost jobs/month
- Average job value: $450 (mix of service calls and bigger tickets)
That works out to 40 lost jobs at $450 each, which is $18,000 per month, or $216,000 per year.
And that's before counting the high-ticket after-hours emergencies. A $9,000 system replacement that went to a competitor at 11 p.m. doesn't even fit the "average job" line.
Run Your Own Numbers
Plug in your real figures. Even a cautious estimate, say 15% missed and a $300 average ticket, usually lands in the tens of thousands of dollars a year. For most contractors, missed calls are the single largest invisible leak in the business.
The Fix Is Simpler Than Hiring
You don't need to add staff or work later nights. An AI receptionist for home service contractors answers every call on the first ring, 24/7, including the after-hours and surge calls you miss today. It qualifies the lead and books the job into your CRM. Owners using it answer 100% of calls and routinely recover leads that used to vanish into voicemail.
Whether you run HVAC, plumbing, roofing, or electrical, the math is the same. Stop the leak and the system pays for itself many times over.
