The short answer, for anyone who wants the numbers up front: independent call studies have found that roughly 62% of phone calls to small businesses go unanswered, only about 37.8% ever reach a live person, and about 85% of callers who hit voicemail never call back. They call the next result instead. For a service business, the estimated cost of that gap runs to $126,000 a year.

Those are three different studies measuring three different things, so it is worth being precise about each.

Where the 62% comes from

The 62% figure comes from a study by 411 Locals, which placed real calls to 85 small businesses across 58 industries during normal business hours and recorded what happened. Most calls rang out, hit voicemail, or reached an automated dead end; only 37.8% connected to a human being. This was not an after-hours study. These were businesses that were, in theory, open.

The reason is rarely negligence. It is physics. A plumber under a sink cannot answer a phone. A two-person front office cannot answer three simultaneous calls. A solo owner driving between jobs is, legally and practically, unavailable. The call volume of a healthy small business exceeds the answering capacity of its humans at exactly the moments the business is busiest, which is to say, at exactly the moments new customers are most likely to be calling.

Why voicemail doesn't catch the fall

The 85% figure comes from Numa's Small Business Phone Report: the overwhelming majority of callers who reach voicemail simply hang up and dial a competitor. The behavior makes sense from the caller's side. Someone with water coming through a ceiling, or a toothache, or a Saturday free to tour apartments is not leaving a message and waiting. They are working down a search results page until a human, or something that sounds like one, picks up.

Voicemail does not capture demand. It timestamps the moment demand walked to a competitor.

What the gap costs

Invoca's call intelligence research puts the average annual revenue lost to unanswered calls at about $126,000 for a service business. You can sanity-check that with simpler math: in the trades, a single missed call is commonly valued around $1,200, the average booked job that went elsewhere. At even two genuinely missed opportunities a week, the annual number stops looking exaggerated.

What actually closes the gap

There are only three real options, and they sort cleanly by economics. Hire a receptionist: full coverage during their shift, roughly $35,000–45,000 a year, and the phone still goes unanswered nights and weekends, when a large share of consumer calling happens. Use a human answering service: 24/7 coverage billed per call or per minute; published entry pricing at the major services runs roughly $245–293 a month for a few dozen calls or minutes, with overage fees as volume grows. Use an AI receptionist: software pricing, always on, answering from knowledge you approve, the newest option, and the one changing the math fastest.

We build one of those AI options, so weigh our view accordingly: Rocketship's receptionist answers your existing number 24/7, books appointments on the call, and connects callers to a human live when one is needed, from $24.99 a month plus a $5 line. But whichever route a business chooses, the studies above point at the same conclusion: the phone is the highest-intent channel most small businesses have, and the default configuration, humans when available and voicemail otherwise, quietly loses most of it.
