Missed Call Revenue Calculator
Enter how many calls you miss in a week and what an average job is worth. The calculator shows roughly what those calls could be worth each month if someone answered them, using a booking rate of one in nine, a working assumption printed under the result. It is sample math, not a promise.

Assumption
Based on one in nine missed calls becoming a booked job once it is answered, the same rate the example roadmap uses. The roadmap replaces it with your own call log.

Book a RoadmapHow to Calculate Revenue Lost From Missed Calls
Missed calls per week, times 4.3 weeks in a month, times the share that would have booked, times your average job value. In a worked example, a three-truck HVAC shop that misses 8 calls a week at a $400 average job loses about 34 calls a month; at one in nine, that is about 3.8 booked jobs, or roughly $1,530 a month.
Why One in Nine?
It is a deliberately low working assumption, the same rate every example on this site uses. Some missed callers leave a voicemail, some call back, and some were never going to book. Counting only one in nine keeps the estimate from overstating the problem. Your own call log and booking rate should replace it, and the roadmap does exactly that.
What Counts as a Missed Call?
Any call nobody picked up live: calls that rang out, calls that went to voicemail and weren't returned the same day, and after-hours calls. Your phone system's call log shows them. Count a normal week, not your busiest or slowest.
What to Do With the Number
Compare it with the cost of answering those calls. For a small shop, phone and AI software for an after-hours receptionist runs about $50 to $150 a month; a done-for-you build is a one-time cost, and it should pay back in under six months. See how it works in practice in missed call text back for HVAC and an AI receptionist for plumbers, or check the home services and dental pages. The $500 roadmap replaces every assumption here with your own numbers.
Frequently Asked Questions
- How do I calculate revenue lost from missed calls?
- Multiply your missed calls per week by 4.3 to get a month, multiply by the share that would have booked if someone answered, then multiply by your average job value. This calculator uses one in nine as the booking rate, a working assumption, so 8 missed calls a week at a $400 job comes to about $1,530 a month.
- How much does a missed call cost a small business?
- It depends on your average job and how many missed callers would have booked. At the calculator's working assumption of one in nine, each missed call is worth about one ninth of an average job: roughly $44 for a $400 job. Your own call log and booking rate replace that assumption.
- Will customers call back if I miss their call?
- Some leave a voicemail or call back, and many try the next business on the list, especially for urgent work. This calculator does not assume every missed caller is lost; it counts only one in nine as a job you would have booked, which keeps the estimate on the low side.
- What is the average missed call rate for a small business?
- We don't quote a single industry figure, because it varies with staffing, season, and hours. Your phone system's call log shows your own rate: count calls that went unanswered or to voicemail over a normal week. The $500 roadmap measures it for you and replaces every assumption on this page.
