What are missed calls costing you?
A free calculator from Keres AI. Four inputs, transparent math: see how much revenue slips away every month when calls go unanswered, and how much an AI receptionist could recover.
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, Keres AI’s working assumption is that most don't leave a message, and fewer still wait for a callback, because the next business on the list is one tap away. Your competitor answers, gets the job, and your marketing spend that drove that lead is wasted.
The after-hours window is the worst. Keres AI estimates that 30–45% of service calls arrive outside business hours, at night, at weekends and on holidays, which is exactly when most offices are closed. That range is an estimate, not a measured figure. 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
Remi by Keres AI answers every call it receives in two rings, around the clock. The moment a call comes in, Remi picks up, qualifies the caller and books the appointment before they have a chance to call anyone else, and a call Remi could not take gets a text back within 60 seconds. Fewer calls end in voicemail, and the revenue leak this calculator measures shrinks with them.

Questions
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%, a Keres AI assumption for home services, not a measured industry figure). 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?
Remi by Keres AI answers every call it receives in two rings, 24/7, and texts back any call it could not take within 60 seconds, so far fewer calls end in voicemail. 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.
