What share of business calls go unanswered?
Analysis of contractor phone lines puts the unanswered share around 62% (ServiceTitan analysis of 50,000+ contractor phone lines). The number looks implausible until you map when calls arrive: the morning dispatch rush while everyone is coordinating, mid-job hours when hands are full, and evenings after close. Each of those windows is precisely when nobody can pick up, which is why longer office hours alone move the number less than owners expect. The distribution matters more than the total — a business that answers 90% of Tuesday-morning calls can still miss most of its after-hours emergency calls, which are the highest-value calls it gets.
- 62% — of calls to home-service businesses go unanswered (ServiceTitan analysis of 50,000+ contractor phone lines)
- Misses cluster in three bands: morning rush, mid-job, after hours
- After-hours calls skew urgent, and urgent callers buy fastest
How many callers leave a voicemail, and how many call back?
Consumer phone-behavior research consistently finds that 86% of callers will not leave a voicemail at all. Of callers who reach voicemail, 85% of callers who reach voicemail never call that business back — and ~75% call a competitor next — usually within minutes. Read together, the three figures describe a simple behavior: a caller with a problem treats an unanswered line as a "no" and moves to the next search result. Voicemail is not a safety net; it is a record of the lead after it left.
What is the revenue math on a missed call?
The standard formula: average job value × close rate × monthly missed calls = monthly revenue at risk. A worked example — a home-services business with a $400 average ticket, a 50% close rate on qualified enquiries, and 30 missed calls a month is exposing roughly $6,000 a month in expected revenue. Two honest adjustments keep the estimate defensible: strip out spam and wrong numbers (often a fifth of inbound volume on a listed line), and weight after-hours calls above the average, because a 7pm call about a failed water heater is closer to a purchase than a Tuesday price-shopper.
- Average job value × close rate × missed calls = revenue at risk
- Example: $400 ticket × 50% close × 30 misses ≈ $6,000/month exposed
- Subtract spam; weight after-hours calls above average
What do these numbers imply about recovery tactics?
Speed dominates every other variable. The research picture — most callers refusing voicemail, most voicemail-leavers never calling back, and most missed callers dialing a competitor within minutes — means any recovery tactic that depends on the caller acting again (voicemail, a callback hours later) starts from a losing position. Tactics that act instantly on the business's side — answering the call in the first place, or texting the missed caller within seconds — are the only ones operating inside the window before the caller's next search. That is the behavioral case for missed-call text-back and for 24/7 answering, and it is why both beat longer office hours per dollar spent.
