Missed call statistics: what verified studies actually show
Unanswered-call statistics are widely repeated and often exaggerated. Here is what the traceable studies measured, their sample sizes, and what they don't tell us.
The most-cited figure: 62% of calls to small businesses go unanswered
The statistic that small businesses fail to answer 62% of their incoming phone calls comes from a study published by 411 Locals, a local-SEO and directory company. The study monitored phone call activity at a sample of small businesses over a 30-day period and found that 62% of calls went unanswered during that window.
This figure is frequently misattributed to Harvard Business Review or to academic research. It is not — it comes from 411 Locals' own study, published on their site, and it has not been independently replicated or peer-reviewed. The sample and industry mix are not fully documented in the public version of the report, which limits how confidently the number generalizes to any specific trade or region.
Because the underlying study has known documentation gaps (sample composition, exact industries covered), treat 62% as a directional industry figure — plausible and widely cited, but not a rigorously peer-reviewed academic result.
What each commonly cited statistic actually measured
| Claim | Source | What was measured | Limits |
|---|---|---|---|
| 62% of calls to small businesses go unanswered | 411 Locals study | Call answer/no-answer rate across a sample of small businesses monitored for 30 days | Sample size and industry breakdown not fully disclosed; not peer-reviewed; single vendor-run study |
| Home services businesses miss a substantial share of inbound calls during and after business hours | Multiple call-tracking vendors (Invoca, CallRail) publish industry benchmark reports | Answer rates and call outcomes across calls tracked through each vendor's own platform | Vendor-tracked calls are a convenience sample of that vendor's customers, not a random sample of the industry; exact current published rates should be checked against the vendor's live report before citing a number |
Only the 411 Locals figure is used elsewhere on this site as a specific percentage; other vendor reports are referenced directionally without an unverified number attached.
Why service-business calls go unanswered
For contractors and field-service businesses specifically, calls are commonly missed for structural reasons rather than neglect: the owner or technician is on a job site or under a vehicle, on another call, driving, or it's after hours or during a lunch break. Service businesses are also disproportionately reliant on a single phone line answered by an owner-operator or a small office staff, unlike larger businesses with dedicated call centers.
A missed call from a prospective customer differs from a missed call from an existing customer in one important way: a new caller usually has other options and can call a competitor immediately, while an existing customer is more likely to leave a message or call back. This is a plausible operational explanation for why missed calls are frequently framed as a revenue risk specifically for new-customer acquisition, though we are not aware of a study that isolates this effect with hard numbers for the trades.
What this means operationally
Even taking 62% as a rough industry figure rather than a precise universal rate, the operational implication is the same: a phone that is not staffed continuously — nights, weekends, during jobs, during high call volume — will miss a meaningful share of inbound calls. Whether that translates into lost revenue for a specific business depends on additional factors covered on the missed call ROI page: how many of those callers would have booked, and at what average job value.
The practical questions to ask about your own business are: what share of your inbound calls currently go to voicemail or ring out, do you track that number at all, and what happens to a caller who doesn't reach a person. Call-tracking software, a phone carrier's own call log, or a receptionist service's reporting can usually answer the first question directly, without relying on an industry-wide average.
Frequently asked questions
Is the 62% missed-call statistic from Harvard Business Review?
No. It comes from a study published by 411 Locals. It is commonly and incorrectly attributed to Harvard Business Review, likely because HBR published a separate, unrelated study on lead response time in 2011.
Has the 62% figure been independently verified?
Not to our knowledge. It is a vendor-published study without full public disclosure of sample composition, and it has not been peer-reviewed or replicated by an independent researcher.
Do missed-call rates vary by industry?
Almost certainly, but we have not found a rigorously sourced breakdown by trade (plumbing, HVAC, electrical, etc.) with a transparent methodology. Vendor benchmark reports (e.g., Invoca, CallRail) publish industry splits based on their own tracked call volume, which is a convenience sample, not a random sample of the industry.
