Most missed-call statistics quoted online cannot be traced to a real study. This page is the stricter version: twelve figures that do trace to a named source, each cited inline and linked below, plus an honest list of the popular numbers we could not verify.
The most cited field measurement comes from 411 Locals (2016), a local-SEO firm that monitored inbound calls at 85 businesses across 58 industries for 30 days. Only 37.8% of calls were answered by a live person. Another 37.8% went to voicemail, and 24.3% got no response at all, meaning about 6 in 10 calls were unattended. Even more telling: 70% of the businesses studied answered less than half of their calls.
It is a single study and a decade old, so treat it as a benchmark rather than a law. But its core finding keeps being reproduced: owner-operated businesses miss calls because the owner is the one doing the work, and most US small businesses are one-person operations where the person answering the phone is also the person on the job.
Meanwhile the phone itself is under pressure. Hiya (State of the Call, 2025) reports that 80% of calls from unrecognized numbers now go unanswered, and the YouMail Robocall Index (2026) counted about 4.3 billion robocalls to US phones in June 2026 alone. Callers still call, but they are more suspicious and less patient.
The cleanest primary data on caller behavior is older than most assume, but it comes from Google. In a 2013 study Google commissioned from Ipsos covering 3,000 mobile searchers, 70% had used click-to-call directly from search results, and 61% said calling is most important in the purchase phase. The finding that matters here: 47% said that when a business has no call option, they feel frustrated and are more likely to explore other brands.
Expectations have only hardened since. The Zendesk CX Trends 2026 report found 74% of consumers now expect customer service to be available 24/7, and 88% expect faster responses than they did a year earlier. A HubSpot (2022) consumer survey put a finer point on speed: 90% of customers rate an immediate response as important or very important for a service question, and 60% define immediate as 10 minutes or less.
The foundational dataset is the 2007 Lead Response Management Study, led by James Oldroyd using InsideSales.com platform data: three years of records from six companies, more than 15,000 leads, and over 100,000 call attempts. The odds of contacting a lead dropped about 100-fold when the first call moved from 5 minutes to 30 minutes after the inquiry. The odds of qualifying that lead dropped about 21-fold over the same window, and fourfold just between 5 and 10 minutes.
A 2011 Harvard Business Review audit (Oldroyd, McElheran, Elkington) then measured how real companies perform. Of 2,241 US companies sent a test web lead, only 37% responded within an hour, 16% within one to 24 hours, 24% took more than 24 hours, and 23% never responded at all; average response time was 42 hours. Companies responding within an hour were nearly 7 times more likely to qualify the lead than those waiting even an hour longer, and more than 60 times more likely than those waiting 24 hours or more.
Both studies measured web-form leads, not phone calls. The honest inference: an inbound call is the same race with less slack, because the caller is on the line now and a missed call is not a slow response, it is no response.
Two official numbers frame why this matters at scale. The US Census Bureau (Business Formation Statistics, 2024) counted a record 5,481,437 new business applications in 2023. The SBA Office of Advocacy (2024) estimates about 34.8 million small businesses operate in the US, 99.9% of all businesses. Most have no front desk; when the phone rings, there is often literally nobody whose job it is to answer.
There is no verified universal cost per missed call. The large figures you may have seen, such as the $75 billion annual loss from NewVoiceMedia (2018), measure poor customer service broadly, not missed calls specifically. The only defensible way to price a missed call is with your own numbers. Here is the formula, with every assumption labeled:

For the staffing comparison, the official baseline is the BLS (2024) median receptionist wage of $37,230 per year, which buys 40 hours of coverage out of the 168 hours in a week, about 24%. Fully loaded cost (taxes, benefits, turnover) runs higher still, though that loading factor is an estimate, not a BLS figure.
Part of the value of this page is what is missing from it. Each of these circulates widely in marketing blogs, and each failed our traceability test:
If you find a primary source for any of these, we would genuinely like to see it.
About 62% in the most cited field study: 411 Locals (2016) monitored 85 businesses across 58 industries for 30 days and found only 37.8% of calls answered live, 37.8% going to voicemail, and 24.3% with no response at all. 70% of businesses answered less than half their calls.
Minutes, not hours. The 2007 Lead Response Management Study (Oldroyd, InsideSales.com data) found contact odds drop about 100-fold between a 5-minute and a 30-minute response, and Harvard Business Review (2011) found firms responding within an hour were nearly 7 times more likely to qualify the lead.
Yes. Google/Ipsos (2013) found 70% of mobile searchers had used click-to-call and 61% rated calling most important in the purchase phase. Zendesk (2026) found 74% of consumers now expect 24/7 service availability and 88% expect faster responses than a year ago.
There is no credible universal average. The honest formula is missed calls per month, times the share that are real prospects, times your close rate, times your average customer value. Our calculator runs it with your numbers.
Full disclosure: we build an AI receptionist, so we have an interest in this data. It answers every call around the clock for a flat published price, $149, $349, or $799 per month, versus the $37,230 median annual wage of a receptionist covering 40 of the week's 168 hours. The numbers above stand on their own sources either way.
The data says the phone still decides who wins the customer. Hear the AI answer live, then decide.
