Missed-call statistics, checked.

Most numbers you've seen have no source. Here are the ones that do, with who measured them, how many, and what they don't show.

Updated · by the Nerro team

Numbers with a source.

We opened each one at its source on October 30, 2026.

  1. 56%

    of calls to businesses were answered by a person, across all industries. For calls over 15 seconds, it was 65%.

    Invoca, Lead Conversion Benchmarks Report, 2026. Sample: 70 million calls to businesses that use Invoca's call tracking.

    What it doesn't show: The time period isn't stated, and the report doesn't define a missed call. These are Invoca's own customers, often bigger companies, not a random sample.

  2. 28%

    of business calls go unanswered on average, from CallRail's own data.

    CallRail, press release, 2026. Sample: Not stated.

    What it doesn't show: The release gives no sample, time period or method. It comes from a company that sells phone tools.

  3. 27%

    of calls to home services businesses are not answered.

    Invoca, blog post, 2024. Sample: Not stated.

    What it doesn't show: No sample or method is given on the page. Treat it as a rough guide for home services only.

  4. 69%

    of missed business calls got no call back within 48 hours.

    Quo, small business callback data, 2026. Sample: 16.7 million missed calls logged by Quo users over three months.

    What it doesn't show: Quo users only. A call back means a call to the same number within 48 hours, so a text reply may not count.

  5. 78%

    of US consumers have given up on a business after an unanswered call. 82% say they'll call a competitor if you don't answer, and 21% immediately call another business. 42% leave a voicemail.

    CallRail, consumer survey, 2025. Sample: 1,000 US consumers.

    What it doesn't show: This is what people say they do, not what they were seen doing. The dates the survey ran aren't given, and CallRail sells call tools.

  6. 40%

    of law firms answered a call from a would-be client, down from 56% in 2019. 48% neither answered nor called back.

    Clio Legal Trends Report, as reported by the Illinois Supreme Court Commission on Professionalism, 2024. Sample: 500 US law firms, called by a research firm posing as a client.

    What it doesn't show: Law firms only. It shows whether the phone was picked up, not what happened to those clients.

  7. 14.1%

    of inbound calls to residential HVAC shops came outside business hours in June 2025, falling to 9.8% in October. Weekend calls peaked at 4.9% in August.

    ServiceTitan, State of the Trades, 2026. Sample: Residential HVAC contractors on ServiceTitan with calls in all 12 months of 2025.

    What it doesn't show: Not nationally representative, in ServiceTitan's own words. Off-hours means weekdays before 8 AM or after 5 PM, plus weekends. HVAC only.

  8. 19%

    of US adults answer their cellphone when an unknown number calls. 67% say they usually don't answer.

    Pew Research Center, 2020. Sample: 10,211 US adults, surveyed July 13 to 19, 2020.

    What it doesn't show: From 2020, and about personal cellphones. It hints at why a call back from a number people don't know may go unanswered too.

  9. 40%

    of home service owners name customer communication as one of the biggest drains on their time.

    Jobber, 2026 Home Service Trends Report, 2026. Sample: 1,050 US home service business owners, surveyed in December 2025.

    What it doesn't show: Owners' own view of their time, not a count of calls. Jobber sells software to these owners.

Numbers we couldn't trace.

You'll see these on many sites. We looked for where each one started. Here's what we found, and the closest number that does have a source.

“85% of callers who reach voicemail never call back.”

We found it on many sites, credited to different places or to nothing. We couldn't find a study that measured it.

Closest real number: 21% of consumers say they immediately call another business when no one answers (CallRail, 2025).

“62% of calls to small businesses go unanswered.”

This one has a source, but it's old and small: 85 businesses watched for 30 days in 2016 (411 Locals). It shouldn't be used as a number for today.

Closest real number: 56% of calls were answered by a person across 70 million calls (Invoca, 2026).

“80% of callers won't leave a voicemail.”

The oldest copy we found is a 2014 trade magazine item that credits "Forbes" but names no study. We couldn't find the Forbes piece.

Closest real number: 42% of consumers say they leave a voicemail (CallRail, 2025).

“Small businesses lose $126,000 a year to missed calls.”

We found no study that counted it. Any figure like this depends on how many calls you miss and what a job is worth to you.

Closest real number: Your own numbers, in the missed-call calculator.

“62% of callers call a competitor.”

We couldn't find a study behind it.

Closest real number: 82% of consumers say they'll call a competitor if you don't answer (CallRail, 2025). That's what people say, not what they did.

“78% of customers buy from the first business that responds.”

It's credited to a study we couldn't find, with no date or sample. Don't mix it up with CallRail's 78%, which is about giving up after an unanswered call.

Closest real number: None we could check.

“Over 40% of calls come after hours.”

We found no data set behind it.

Closest real number: 9.8% to 14.1% of calls to residential HVAC shops, by month (ServiceTitan, 2026).

Count your own.

A national number can't tell you about your phone. One week of your own call log can.

  1. 1

    Pick one normal week.

    Not a holiday week, and not your busiest. Write down the dates.

  2. 2

    Open your call log.

    Your phone's recent calls, or your business line's online call history. Count every call in that week, then count the missed ones. A call that went to voicemail counts as missed, even with no message.

  3. 3

    Check who you called back.

    For each missed call, did you call back that day? Count the ones you didn't. That's the number to fix first.

Then put your numbers in the missed-call calculator to see what those calls cost a month. More on the fixes: answering vs missing the call, calling leads back fast, after-hours calls and forwarding only the calls you miss.

How we checked.

Checked on . We read each original, not a page quoting it. Where the original wouldn't load for us, we used a trusted page that reported it and said so.

We quote each number the way its source said it, with its year, its sample and what it leaves out. Most of these come from companies that sell phone tools, so we say that too. We recheck every three months.

Questions about missed calls.

Something else? Ask us.

What percent of business calls go unanswered?

It depends on who measured it. Invoca found 56% of calls were answered by a person across 70 million calls (2026). CallRail says 28% of business calls go unanswered on average (2026). Invoca found 27% unanswered for home services (2024).

Do callers call back if no one answers?

Some do. In a 2025 CallRail survey of 1,000 US consumers, 21% said they immediately call another business. We couldn't find a study behind the "85% never call back" number.

How many callers leave a voicemail?

42% of consumers said they leave a voicemail in CallRail's 2025 survey. That's what people say they do, not a count of real calls.

Is the 62% unanswered number real?

It comes from a 2016 study of 85 businesses over 30 days. It was real then, but it's old and small, so it shouldn't stand for today.

How often do law firms answer the phone?

In Clio's 2024 secret-shopper study of 500 US law firms, about 40% answered, down from 56% in 2019. 48% neither answered nor called back.

How many calls come after hours?

For residential HVAC on ServiceTitan, 9.8% to 14.1% of calls came outside business hours, by month, in 2025. We found no data behind the "over 40%" claim.

Can I use these numbers in my article?

Yes. Link to the original source for each number, and to this page if it helped. If you have a primary source for a number we couldn't trace, email support@nerro.co and we'll check it.
