What are missed calls costing you?
Four inputs, transparent math. See how much revenue slips away every month when calls go unanswered — and how much an AI receptionist recovers.
Missed-call revenue loss = monthly call volume × missed-call rate × close rate × average ticket value. For a business taking 250 calls/month at a 60% answer rate with a $680 average job, that's roughly $17,000 in lost revenue every month — over $200,000 per year going to competitors who answered.
Why missed calls cost more than you think
When a caller hits voicemail, the data is clear: most don't leave a message, and fewer still wait for a callback. They call the next business on the list. Your competitor answers, gets the job, and your marketing spend that drove that lead is wasted.
The after-hours window is the worst. A full 35–45% of service calls come after 5 PM or on weekends — exactly when most businesses go dark. An HVAC emergency at 9 PM means the homeowner calls until someone answers. That someone should be you. (See the full missed-call statistics.)
What changes with an AI receptionist
Keres AI answers every call in two rings, around the clock. The moment a call comes in, the AI picks up, qualifies the caller, and books the appointment before they have a chance to call anyone else. The missed-call rate drops to near zero — and so does the revenue leak this calculator quantifies.

Missed-call calculator FAQ
How do you calculate lost revenue from missed calls?
Missed leads = monthly leads × (100% − answer rate). Lost jobs = missed leads × close rate (default 25%, the industry-median answered-lead close rate for home services). Lost revenue = lost jobs × your average job value. After-hours percentage highlights the leads most at risk.
What is a typical answer rate for service businesses?
Many service businesses answer only 60–75% of inbound calls, and far fewer after hours. Every unanswered call is a lead that usually calls a competitor.
How does an AI receptionist recover this revenue?
An AI receptionist answers 100% of calls in two rings, 24/7, so the missed-call gap closes to nearly zero. See the AI receptionist page.
Which industries lose the most to missed calls?
HVAC, plumbing, and roofing lose the most — emergency calls go to the first business that answers. Towing, dental, and real estate follow. Any service business where the next call is the next job is at high risk.
