**Quick answer:** Appointment no-show rates typically run between **5% and 30%** depending on the setting, and the research is consistent that **reminders help**. In a Cochrane systematic review of randomized trials, attendance rose from **67.8% with no reminder to 78.6% with a text-message reminder**. Below is a sourced roundup you can rely on — every figure links to its source.

## Key no-show statistics at a glance

- No-show rates across healthcare settings commonly range from **5% to 30%**, varying by specialty and how they are measured. ([MGMA](https://www.mgma.com/mgma-stat/patient-no-shows-still-an-issue-despite-more-automated-reminders))
- Text-message reminders raised appointment attendance from **67.8% to 78.6%** in a Cochrane review of randomized trials. ([Cochrane / PubMed](https://pubmed.ncbi.nlm.nih.gov/22786507/))
- In a pediatric randomized controlled trial, the no-show rate was **23.5% with reminders vs 38.1% without**. ([NCBI](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5227159/))
- Patients with an active patient portal had a **6.2%** no-show rate vs **7.9%** without one, in a 2024 analysis. ([Epic Research](https://www.epicresearch.org/articles/patient-portal-use-associated-with-21-million-fewer-visit-no-shows-in-2024/))
- A widely cited industry estimate puts the annual cost of missed appointments to the U.S. healthcare system at about **$150 billion**. ([HCI Innovation Group](https://www.hcinnovationgroup.com/clinical-it/article/13008175/missed-appointments-cost-the-us-healthcare-system-150b-each-year))

## How common are appointment no-shows?

There is no single "average" no-show rate, because studies count them differently and rates swing widely by setting. Published figures generally land between **5% and 30%**. Primary care often sits toward the lower end, while behavioral health and certain specialties run higher ([MGMA](https://www.mgma.com/mgma-stat/patient-no-shows-still-an-issue-despite-more-automated-reminders)).

The trend is not simply improving on its own. In a 2024 MGMA poll, most medical groups reported their no-show rates had **stayed the same or decreased**, but a meaningful share still saw them rise ([MGMA](https://www.mgma.com/mgma-stat/patient-no-shows-still-an-issue-despite-more-automated-reminders)). And no-shows are not a healthcare-only problem — any appointment-based business, from salons to trainers to trades, loses the same way when a booked slot goes empty.

## How to calculate your no-show rate

Your no-show rate is the share of booked appointments where the client didn't turn up and didn't cancel in time:

**No-show rate = (no-shows ÷ total booked appointments) × 100**

For example, 6 no-shows out of 120 booked appointments in a month is a 5% no-show rate. Track it monthly and count late cancellations separately, so you can see whether reminders are moving the number. To put a dollar figure on it, try the free [no-show cost calculator](https://www.smsreminder.app/tools/appointment-no-show-calculator/).

## What do no-shows cost?

The cost of a missed appointment is more than one empty slot: it is the prep time, the staff time, and the chance to have booked someone else. At scale, a **widely cited industry estimate** puts the annual cost of missed appointments to the U.S. healthcare system at roughly **$150 billion** ([HCI Innovation Group](https://www.hcinnovationgroup.com/clinical-it/article/13008175/missed-appointments-cost-the-us-healthcare-system-150b-each-year)). Treat that as an estimate rather than a precise measurement — but it captures the scale.

For a small business, the math is simpler: multiply your average appointment value by the number of no-shows you get each month. Even a small reduction adds up across a full calendar.

Want to run these numbers against your own business? The [appointment no-show cost calculator](https://www.smsreminder.app/tools/appointment-no-show-calculator/) estimates what missed appointments may be costing you each month.

## Do appointment reminders actually reduce no-shows?

Yes — this is one of the better-evidenced findings in the area. The strongest evidence is a **Cochrane systematic review** of randomized controlled trials:

| Reminder type | Appointment attendance |
|---|---|
| No reminder | 67.8% |
| Text-message (SMS) reminder | 78.6% |
| Phone-call reminder | 80.3% |

Text reminders performed **similarly to phone calls**, at lower cost per attendance ([Cochrane / PubMed](https://pubmed.ncbi.nlm.nih.gov/22786507/)). Individual trials point the same way — a pediatric randomized controlled trial found a no-show rate of **23.5% with reminders vs 38.1% without** ([NCBI](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5227159/)).

## Why text reminders work

Two things make text reminders effective. First, **texts get seen** — they are opened far more reliably than email. Second, and more importantly, they **lower the effort of responding**. A client who can confirm with a one-word reply is more likely to act than one who has to open a link, log in, or call back during business hours.

That is also why [*two-way* reminders](https://www.smsreminder.app/guides/conversational-appointment-reminders/) — ones a client can reply to in order to confirm, cancel, or ask to reschedule — tend to outperform one-way notices: they remove the steps between "I got the reminder" and "I responded." The same logic shows up in the patient-portal data, where giving patients an easy digital touchpoint was associated with **fewer no-shows (6.2% vs 7.9%)** ([Epic Research](https://www.epicresearch.org/articles/patient-portal-use-associated-with-21-million-fewer-visit-no-shows-in-2024/)).

## What Kalama's own data adds

We don't track attendance, so we can't give a no-show rate of our own. But two patterns in Kalama's anonymised 2026 data explain where no-shows come from: **about 1 in 4 online bookings is for an appointment less than 24 hours away**, so a day-before reminder misses them, and **about 1 in 10 client replies to a reminder is a cancellation**, which you can still refill. [See the data and what to do about it](https://www.smsreminder.app/google-calendar-sms-reminders/#kalama-data).

## How Kalama (formerly SMS Reminder) helps

Kalama (formerly SMS Reminder) sends automatic text reminders from your Google Calendar before each appointment, and clients can reply to confirm or cancel — or tap the link. If they need a different time, they ask and finish rescheduling on the booking page. It puts the research above into practice: timely texts that are easy to respond to.

## Frequently asked questions

**How do you calculate a no-show rate?**

Divide the number of no-shows by the total number of booked appointments for the period, then multiply by 100. For example, 6 no-shows out of 120 appointments is a 5% no-show rate.

**What is the average appointment no-show rate?**

It varies widely by setting — published figures range from about 5% to 30%. Primary care often sits at the lower end, while behavioral health and some specialties run higher. There is no single universal rate because studies measure it differently.

**Do text message reminders actually reduce no-shows?**

Yes. A Cochrane systematic review of randomized trials found appointment attendance rose from 67.8% with no reminder to 78.6% with a text-message reminder — a level of improvement similar to phone-call reminders, at lower cost.

**How much do missed appointments cost?**

A widely cited industry estimate puts the cost to the U.S. healthcare system at around $150 billion a year. It is an estimate rather than a precisely measured figure, but it reflects the scale of the problem across providers.

**What is the single best way to reduce no-shows?**

The research points to timely reminders that make it easy to respond. Reminders clients can reply to — to confirm, cancel, or reschedule — reduce the effort of acting, which is what drives higher attendance.
