# Missed call cost calculator for HVAC, plumbing & electrical businesses

Enter your weekly calls and typical job value. See a low–high range based on published unanswered-call assumptions.

**In short:** Enter weekly calls and a typical job value to get a low-to-high range of monthly and yearly revenue at risk from unanswered calls. The range uses published unanswered-call shares of 14% and 27% and a 42% default booking rate you can change.

We assume 3% of missed callers leave voicemail and are recovered at your booking rate; all other missed callers are assumed lost. The source reports fewer than 3%. These are scenarios, not measured losses for your business. Use your actual booking rate if you know it.

## 01 / About the estimate

### Is this my actual lost revenue?

No. These are scenarios using your inputs and published benchmarks. Your call logs, repeat callers, and actual booked jobs will give you a more accurate picture.

### Why show a range?

The model uses 14% and 27% unanswered-call shares from different sources. The difference shows how sensitive the estimate is to your actual missed-call rate.

### Can I change the booking rate?

Yes. The default is 42%, based on a ServiceTitan benchmark. Replace it with the share of relevant calls your business typically turns into booked jobs.
