How many calls does a small business miss?
There is no single national number. Here is what each study counted, why they disagree, and how to count your own calls in one week.

In this article
Search for how many calls small businesses miss and you will find confident, round numbers. Many trace back to a vendor blog quoting another vendor blog. Some trace back to nothing.
So we went to the studies themselves. The short answer is that there is no single national number. Each study counts something different: calls to its own customers, calls placed by a secret shopper, calls in one industry or one month.
Read side by side, they still say something useful. And they point to the number that matters more than any of them: your own.
What each study actually counted
These are the six studies we could trace to their source, with what each one measured. Most come from companies that sell call answering or call tracking, including some that compete with SpiderLabs. Their data is real, but it describes their own customers or their own test, not every business.
| Study | Whose calls | What it found |
|---|---|---|
| 411 Locals, 2016 | 85 businesses in 58 industries, over 30 days | 37.8% answered, 37.8% to voicemail, 24.3% no response |
| CallRail, 2025 | Home services businesses on its own platform | 14% of calls missed |
| Invoca, 2026 | Home services businesses on its own platform | 52% answered by a person; 65% leaving out calls under 15 seconds |
| Clio, 2024 | 500 U.S. law firms, called by a secret shopper | 40% answered; 48% could not be reached by phone at all |
| Patient Prism, 2026 | 11.55 million calls to 8,280 dental locations on its platform in 2025 | 31 of every 100 callers hung up before reaching anyone |
| Peerlogic, 2026 | One group of 26 dental practices, February 2026 | 62% answered live |
Why the numbers disagree
They are not measuring the same thing. A secret shopper calling law firms measures whether a stranger gets through. Platform data measures a vendor’s own customers, who bought call tracking because they care about calls.
One study counts voicemail as unanswered. Another counts a caller as reached once the firm calls back. One figure leaves out calls shorter than 15 seconds, which removes misdials and quick hang ups.
So never add these figures together or average them into one rate, and be wary of anyone who does. Taken together they support one modest claim: in every one of these studies, a real share of calls never reached a person.
Read the base before the number
Before you trust a missed call figure, ask three questions. Whose calls were counted? Over what period? Does voicemail count as answered? A number without those answers is a guess with a decimal point.
Not every unanswered call is lost business
Some unanswered calls are robocalls, wrong numbers or regulars who will call back. Others are new customers with a need today, and they are the ones that cost you. No study above can tell you that mix for your business. Your own phone records can.
Count your own in one week
You do not need a study. You need seven days of your own call records, which most phone systems and carriers already keep.
- Export every incoming call for one ordinary week from your phone system or your carrier’s portal: date, time, length and whether someone picked up.
- Mark each call answered, voicemail or unanswered. Count a voicemail as unanswered unless your team called back the same day.
- Split the unanswered calls into open hours and closed hours. They are two different problems with two different fixes.
- Check the numbers that did not get through. A number you have never seen before is the one to care about most.
- Write down three counts: all calls, calls a person answered, and unanswered calls from numbers you did not recognize.
That last count is your number. It is more useful than any national statistic, because it is your callers, your hours and your staff.
If you cannot see them
If your phone system cannot show you unanswered calls, that is the first finding. A business that cannot see its missed calls cannot fix them.
What to do with your number
If most unanswered calls come in open hours, the desk is busy, not careless: the second and third calls ring out while the first caller is being helped. If most come in closed hours, callers are reaching you when nobody is there.
Both have the same cure: something that answers every call, captures who called and why, and hands your team a list in the morning. That is what an AI front desk does. Read what it does and does not do, or how it compares with an answering service.
Common questions
What percentage of calls do small businesses miss?
No single study measures all small businesses. In a 2016 study of 85 businesses by the marketing agency 411 Locals, 37.8% of calls were answered, 37.8% went to voicemail and 24.3% got no response. Newer studies cover one industry each, such as home services or law firms, and each uses its own definitions.
Do most callers leave a voicemail?
Fewer than half say they do. In a 2025 CallRail survey of 1,000 U.S. consumers, 42% said they leave a voicemail when a business does not answer. That is what people say they do, not what they did. We could not trace the more popular voicemail figures to a reliable source, so we do not quote them.
How do I find out how many calls my business misses?
Export one ordinary week of incoming calls from your phone system or carrier, mark each one answered, voicemail or unanswered, and split them into open and closed hours. The unanswered calls from numbers you do not recognize are the ones that matter most.
