Missed call statistics: what unanswered calls cost

Every small business owner knows the feeling: you’re on a roof, under a sink or in a showing, and the phone buzzes in your pocket. You’ll call back later. Will they pick up? This page pulls together the research on how often business calls go unanswered, why customers still call, how people treat unknown numbers and voicemail, and what that means for how you cover the phone.

How we built this list: we only include figures we could trace to the original source, and each one links to it. Independent research (Pew Research Center, the FTC, CTIA) comes first. Studies by vendors that sell call tracking, caller ID or texting software are labeled as vendor research, and we only included vendor studies that describe how they collected their data. Last checked October 2026.

How often business calls get answered

There is surprisingly little public, well-documented data on missed calls. The largest dataset we found that states its method comes from a call-tracking vendor.

• 56% of inbound calls to businesses were answered by a person; for calls longer than 15 seconds the figure was 65%, and for calls over 30 seconds 71% — Invoca (vendor data, 2026, more than 70 million calls across 10 industries, averages across Invoca’s customers)
• 38% of answered calls were sales leads, and 42% of those leads converted on the call — Invoca (vendor data, 2026)
• In home services, 52% of inbound calls were answered by a person, ranging from 32% to 74% across sub-industries such as HVAC, plumbing, pest control and lawn and tree care — Invoca (vendor data, 2026)
• 55% of home services businesses didn’t ask phone leads to buy or book the job — Invoca (vendor data, 2026)

Keep in mind that these are averages across companies that pay for call tracking, often larger businesses running paid ads. A one-person contractor may do better or worse.

What this means for your team: if roughly four in ten calls don’t reach a person even at businesses that measure their phones, assume your own answer rate is lower than you think. Measure it for a month. Then work on the two gaps the data points to: calls nobody picks up, and calls that get picked up but end without a booked next step.

Why customers still call

Texting and forms keep growing, but for expensive or urgent jobs, people still want to talk to someone.

• 44% of consumers prefer calling a business when they need help with a purchase, up from 32% in 2022 — Invoca (vendor survey, 2025, n=1,000 US and UK consumers who made a high-stakes purchase in the prior 12 months, conducted by Sago)
• 67% called a business at some point during their buying journey — Invoca (vendor survey, 2025, n=1,000)
• 84% said human connection is important during high-stakes purchases — Invoca (vendor survey, 2025, n=1,000)
• Americans spent more than 2.4 trillion minutes on voice calls in 2024, 30 billion more than the year before — CTIA (2025, annual wireless industry survey covering 2024)
• 43% of consumers phone a business “always or most of the time” when they reach out, close to text at 46% — EZ Texting (vendor survey, 2026, n=959 US consumers)

What this means for your team: a phone call is often your highest-intent lead. Someone calling about a water heater or a listing is ready to talk now, and a missed call hands that moment to whoever answers next. Treat inbound calls like your most valuable form submissions, and route them the same way. Our guide to lead routing covers who should pick up and when.

Unknown numbers and voicemail

When you call a lead back, you’re an unknown number. The data on how people treat those calls is sobering.

• 19% of US adults say they generally answer calls from unknown numbers; 67% don’t answer but check voicemail, and 14% don’t answer and ignore voicemail too — Pew Research Center (2020, n=10,211 US adults, July 13–19, 2020)
• Only 14% of consumers immediately answer a call from a number they don’t recognize; 41% ignore it and wait to see if the caller leaves a voicemail, and 28% reject it immediately — Hiya (vendor survey, 2026, more than 12,000 consumers in the US, Canada, UK, France, Germany and Spain, fielded by Censuswide Dec. 17, 2025–Jan. 2, 2026)
• 73% agree that businesses should identify themselves in caller ID when they call — Hiya (vendor survey, 2026, 12,000+ consumers in six countries)
• Seeing a verified business name (29%) is the single detail most likely to make people answer a business call, followed by seeing that the number isn’t flagged as spam (24%); 20% say nothing would make them likely to answer — Hiya (vendor survey, 2026)

What this means for your team: a callback is not a guaranteed second chance. Most people will screen it and some won’t even listen to the voicemail. Leave a short voicemail that says who you are and what they asked about, then send a text right after so they can see your name in writing. Calling from the same number your customers already know helps too.

Spam calls shape behavior

Customers aren’t screening you personally. They’re screening the flood of scam calls.

• 68% of US adults say they get scam phone calls at least weekly, and 31% get them at least daily — Pew Research Center (2025, n=9,397 US adults, April 14–20, 2025)
• The National Do Not Call Registry held about 258.5 million active registrations as of Sept. 30, 2025, and robocalls made up most Do Not Call violation complaints — Federal Trade Commission (2025, fiscal-year registry data)
• 34% say their overall trust in phone calls has decreased in the past 12 months, while 16% say it has increased — Hiya (vendor survey, 2026, 12,000+ consumers in six countries)

What this means for your team: you can’t fix spam, but you can stop looking like it. Call leads back quickly while they still expect to hear from you, and pair calls with a text or email that names your business. And only call or text people who asked to hear from you; our TCPA-friendly texting guide covers the basics (general information, not legal advice).

Text back after a missed call

Texting data from vendor surveys suggests a text can rescue a conversation a missed call would lose.

• 42% of respondents said phone calls are the channel they ignore most, versus 8% for SMS — Textmagic and Pollfish (vendor survey, 2025, n=1,800 US adults, March 2025)
• 30% say they texted a business and got no reply — Textmagic and Pollfish (vendor survey, 2025, n=1,800)
• 70% expect a business to reply to a text within one hour — EZ Texting (vendor survey, 2026, n=959)
• For customer questions, 33% prefer texting and 18% prefer phone calls — SimpleTexting (vendor survey, 2026, n=1,000 US consumers, Jan. 7–8, 2026)

What this means for your team: when you miss a call from someone who has agreed to receive texts, a quick “Sorry we missed you, this is Dana from Avery Plumbing. Is this about a repair or a quote?” keeps the lead warm and lets them answer on their own time. Then reply within the hour. For a deeper look at combining both channels, see texting vs calling new leads.

People, AI and the phone

AI voice agents can answer when nobody else can, but customers are clear about one condition.

• 67% prefer human support when AI and human options are equally available — Invoca (vendor survey, 2025, n=1,000 US and UK consumers)
• 77% are more willing to use a brand’s AI assistant when they can easily reach a human — Invoca (vendor survey, 2025, n=1,000)
• 74% prefer AI when it resolves their issue faster than a human would — Invoca (vendor survey, 2025, n=1,000)

What this means for your team: use an AI receptionist to cover the gaps (after hours, weekends, when everyone is on a job), not to hide your team. In Exa, the AI receptionist answers inbound calls, qualifies the caller, checks availability and books appointments, then saves the transcript, recording and summary to the lead’s timeline so a person can follow up. Our AI receptionist guide covers scripts, disclosure and handoff to humans.

Popular stats we left out

You’ll see these numbers on many websites. We couldn’t trace them to an original study with a stated method, so they aren’t on this page:

• “85% of people whose calls go unanswered won’t call back.”
• “80% of callers sent to voicemail don’t leave a message.”
• “62% of calls to small businesses go unanswered.” This is often credited to a 411 Locals study reported around 2016; we couldn’t open the original report.
• Dollar figures for what missed calls cost a “typical” small business per year.

They may be directionally right, but you don’t need them. The traceable data above makes the same point.

Final thoughts

The verified research points one way. A large share of business calls never reach a person, the people calling are often your most motivated leads, and once you miss them, spam-weary customers make it hard to reconnect by phone alone.

You don’t need a call center to fix this. Measure how many calls you miss, decide who covers the phone during busy hours, follow every missed call with a named text where you have consent, and use an AI receptionist for the hours nobody can pick up. If you work in the trades, our contractors page shows how this fits a typical day in the field.
