What a missed call costs, by trade
Based on industry benchmark job values and how missed callers actually behave. Ranges, not false precision.
| Trade | Avg booked call | Cost / missed call | Annual @ 5 missed/wk |
|---|---|---|---|
| HVAC | $450–950 | ~$360–760 | ~$94K–198K |
| Plumbing | $350–750 | ~$280–600 | ~$73K–156K |
| Electrical | $300–650 | ~$240–520 | ~$62K–135K |
| Dental / law (new-client value) | $1,000+ / yr | ~$800+ | ~$200K+ |
How we calculated this
Cost of one missed call = Average booked-call value × Loss rate Annual loss = Cost per missed call × calls missed / week × 52
Loss rate (~80%, conservative): when a call reaches voicemail, ~85% of callers leave no message, and a majority of those hire a competitor — the first business to answer wins the job. We use 80% as a conservative composite. Booked-call valuescome from published home-services operator benchmarks. Everything is shown as a range. This is HelmarOps’ analysis of public sources — not our own call data.
Frequently asked questions
How much does a missed call cost a service business?
For the trades, roughly $240–760 per missed call — driven by the average booked-job value ($300–950) and the ~80% of missed callers who never call back. For an HVAC business missing 5 calls a week, that's about $94,000–$198,000 a year.
Where do these numbers come from?
Two public inputs: average revenue per booked call (home-services operator benchmarks) and missed-caller behavior (industry missed-call studies). We multiply them with a conservative 80% loss rate and show ranges. It's HelmarOps' analysis of public sources, not our own call data.
Isn't voicemail a safety net?
Not really — about 85% of callers who reach voicemail leave no message, and even when they do, the business that answered first wins roughly three out of four jobs.
