Call abandonment rate for veterinary clinics: what's normal and how to measure yours

Ask a practice manager what their clinic's call abandonment rate was last month and the honest answer, almost always, is that they have no idea. The number does not exist anywhere they can see it. A carrier line or a basic VoIP plan reports minutes used and not much else: not how long callers waited before hanging up, how many calls timed out into voicemail, or how many heard a busy signal and never got in.

A clinic that does find its number has nothing trustworthy to compare it to. As of August 2026, there is still no veterinary-specific abandonment rate or average daily call volume in the published literature. We would rather say so plainly than repeat figures we could not trace to a source.

The closest published measurement is a 2025 secret-shopper study of 5,053 US practices in JAVMA, which found 15.1% of booking attempts could not reach a staff member and 8.2% ended after more than five minutes on hold. That is not the same construct as a practice's missed-call rate — it measures new-client wellness calls during business hours, not total call traffic — but it is real, it is peer-reviewed, and it is the number we would use.

So: the definitions, precisely enough to compute; the benchmarks that do exist and where each comes from; and how to get your own number from a carrier export, a tally sheet, or a veterinary phone system that reports it automatically.

The definitions, with formulas

Start with offered calls: every inbound call that reached your number in the period, whether or not anyone picked up.

Answered rate = calls answered by a person ÷ offered calls. A call that rang through to voicemail was not answered, even if the system logs it as completed.

Abandonment rate = calls the caller hung up on before a person answered ÷ offered calls, whether during the auto-attendant, while ringing, or in the queue.

Short abandons — calls that drop in the first 5 to 10 seconds — are mostly misdials, and contact centers usually exclude them. That is reasonable, and it flatters your rate, so pick a threshold, write it down, and keep it every month.

Average speed of answer (ASA) = total time answered calls waited before pickup ÷ answered calls. Abandoned calls are not in it, so ASA can look fine while many callers give up.

Average hold time = total time callers spent on hold after a person answered ÷ calls placed on hold. Many people say "hold time" when they mean the wait before anyone picks up; they are different problems with different fixes.

Service level is "X% of calls answered within Y seconds." ICMI, the contact-center industry body, calls 80/20 (80% within 20 seconds) a moderate objective, not an ambitious one; it describes what most callers experienced, which ASA does not. ICMI also advises against treating abandonment as a standalone KPI, because it measures callers' patience as much as your desk; read it alongside answered rate and service level.

Queue timeouts and overflow to voicemail are calls that waited as long as your system allows and were sent to voicemail, or never entered the queue because it was full. Count them as unanswered, whatever your system calls them.

The benchmarks that exist, and where they come from

None of the following is veterinary. Each can be traced to a named source, which most numbers in this category cannot.

Contact-center guidance. SQM Group, a call-center benchmarking firm, publishes abandonment guidance whose durable direction is lower is better, and past roughly one call in ten you have a problem. Published thresholds vary between sources, so we quote the direction rather than a single number — and treat all of it as large-contact-center guidance: a 3-person front desk should not hold itself to a call center's figures without help.

The closest thing to healthcare data. A peer-reviewed study of the US Department of Veterans Affairs call centers (Griffith et al., American Journal of Managed Care, 2019) is the best data point we have. The VA targeted an average speed of answer at or under 30 seconds and abandonment at or under 5%. Across 285 facilities between 2014 and 2016, ASA improved from 87 to 69 seconds and abandonment fell from 12.0% to 8.3%. A very large health system, working at it for 2 years, got to 8.3%, not 5%.

How long callers will wait. The best published measurement we have is from the JAVMA study above: 8.2% of callers trying to book gave up after more than five minutes on hold. A widely circulated "90-second hang-up point" is sometimes attributed to an AT&T survey; we could not locate that publication, so we do not use the figure. Every benchmark we do use is documented — source, sample, and scope — on our verified statistics page.

What automated menus do to callers. A 2019 Vonage study (Opinion Matters, 2,010 US adults) found 85% had hung up on an interactive voice response (IVR) system and 51% had abandoned a business entirely after a bad automated-phone experience. Top complaints: reason for calling not listed (65%), irrelevant options (63%), could not reach a live person (54%), menu too long (46%). Every one is a design decision a clinic controls.

What one veterinary clinic's numbers looked like

With no veterinary benchmark, the most useful thing we can offer is one clinic's numbers: one general practice, 5 weekdays before and 5 after, our own platform data — a case and not a study. More in what one clinic's phone data showed.

Before the switch, the practice received about 160 inbound calls a day and its team answered about 105. Over 5 days, roughly 280 calls — 35% of everything that rang — were never picked up by a person. Strictly that is an unanswered rate, not an abandonment rate: the old system could not tell a caller who hung up from one sent to voicemail, which is itself the point.

And 35% is the floor. A phone system can only log the calls that reach it. Callers who met a full queue, timed out, or hung up before entering the queue never registered at all. Real unmet demand was larger, and the phones that would have measured it were the phones missing the calls.

After the practice put AI coverage on its lines, an equivalent 5 days recorded nearly 2,000 interactions: more than 1,000 transferred with context to reception, a nurse, or the pharmacy, and about 900 handled on the line (questions, triage, other routine needs). Across all of them, 4.3% of callers asked not to deal with the AI and were moved to a person. As far as we know, that 4.3% is the first opt-out figure published in this category.

For a cost figure, multiply your own unanswered calls by the share that were bookable and your average transaction value; the industry figures we found had no stated basis.

How to measure yours

On a carrier line or basic VoIP plan:

1. Ask the carrier for a call detail record (CDR) export for the main number, 30 to 90 days, with timestamp, wait time before answer, duration, and disposition. Many carriers supply timestamps and durations but not wait time or disposition; with only those you get answered rate and after-hours volume, not abandonment. A 4-second "answered" call is probably a hang-up on the auto-attendant, but you cannot prove it.

2. If the export does not exist, run a tally sheet at the desk for 2 weeks. It undercounts, because the person tallying is also the person answering and the busiest 10 minutes are when the sheet gets ignored — so treat the result as a floor.

3. Log, for every call the desk is aware of: half-hour block; whether a person answered; rough wait (under 30 seconds, 30 to 90, over 90); voicemail or hang-up; hold, and roughly how long; and second-line calls that rang while the first was in use.

4. Separate business hours, the lunch window, and after-hours before computing anything. A day-level average blends a 95% morning with a 60% lunch hour. Voicemail-to-text transcripts give an exact count of after-hours callers who left a message; that is not after-hours demand, because the callers who did not leave one are the ones you are trying to count.

What a modern phone system reports without being asked: offered, answered, and abandoned calls with the short-abandon threshold set once; average speed of answer and average hold time; service level; queue timeouts and overflow to voicemail; voicemail to text; texts counted alongside calls; each by hour of day and by business hours versus after-hours. The hour-of-day view is what tells you where to put the next person.

What actually moves the number

In rough order of effect.

1. Answer more calls in the first 30 seconds, by staffing the peak hour rather than the day. Abandoned calls concentrate in the busiest 60 to 90 minutes, usually first thing and again after lunch. If a quarter of the day's calls arrive between 8 and 9, the fix is a second person on the phones from 8 to 9:30, not all day. Aim at the VA's 30-second ASA for that hour first.

2. Shorten the tree. The Vonage complaints above describe most veterinary auto-attendants. 3 options, a way to reach a person from every branch, no announcements callers must sit through. We have written up phone tree examples for veterinary clinics, with scripts, so you can shorten yours without losing the routing you need.

3. Give people in the queue a way out that is not hanging up. A callback that holds the caller's place, or the option to text from your main clinic number instead. A caller who switches to text has not abandoned; the desk can work texts between check-ins. The caveat: a text nobody answers is a missed call with a written record.

4. Send after-hours and overflow somewhere that answers. Voicemail is where abandoned calls go to be counted, not answered. Voicemail-to-text makes the messages that do arrive faster to act on, but does nothing for the callers who hung up instead of leaving one — which consumer surveys have long found is most of them.

This is where AI on the line earns its keep. PupPilot's AI answers the calls the team cannot get to (after hours, overflow when every line is busy, and when the desk is helping someone at the counter), handles the routine ones, and transfers the call with context to your staff, with the caller's name, patient, and reason for calling already on screen. A caller who asks for a person, or sounds frustrated, is moved to one and added to an opt-out list so their next call skips the AI. It isn't a replacement for your receptionists. It's the part of the phone system that makes sure every call reaches someone — and, because the same system logs those calls, the part that finally lets you count them.

Where to set the first target

Borrow the targets that exist: an abandonment rate of 5% or under and an average speed of answer of 30 seconds or under in the peak hour, with the same short-abandon rule every month, split by business hours, lunch, and after-hours. They come from contact-center and VA practice, not veterinary data, so treat them as a starting line rather than a verdict. For answered rate there is no borrowed target; set one from your own first month (the clinic above started around 65%). The first month's number will probably be worse than you expect; the VA started at 12% abandonment. The number that matters is the second month's, and whether it moved.
