How much is your clinic losing to patient no-shows?

Patients who don't show up are expensive. In the United States, no-show rates run between 15% and 30% of scheduled appointments, and even well-run commercial practices report 5% to 7%. This calculator shows in 30 seconds how much your clinic loses per month and per year, and how much you could recover with automatic reminders and online rescheduling.

What is a no-show, and what does it cost

A no-show is when a patient misses the appointment without telling the clinic. The slot stays empty, the doctor sees nobody, and the overhead (rent, staff, utilities) keeps getting paid. In the United States, missed-appointment rates "remain between 15% and 30%" of scheduled visits, according to a 2024 report in the Annals of Family Medicine. Well-run commercial practices do better: the MGMA DataDive benchmark puts the rate at 5.55% in 2020, 5% in 2021-22 and 6.81% in 2023.

The cost is documented. In the US, no-shows cost the healthcare system roughly $150 billion per year (Healthcare Innovation, 2017), with an average cost of $196 per no-show in a study of ten US Department of Veterans Affairs clinics (BMC Health Services Research, 2016). An independent US practice loses around $150,000 a year to no-shows (Curogram, 2026). Specialties vary: gastroenterology reached 25.7% and audiology stayed at 12.6% in the same VA study.

Why patients no-show

Reason number one is memory. In a survey of patients who missed appointments (BMC Family Practice, 2005), more than 40% said they simply forgot; in a 2026 NEJM Catalyst study, 22% answered "I did not know I had an appointment". Other factors show up consistently across reviews: a long gap between booking and the visit, a history of prior no-shows, younger age and lower income (Health Policy, 2018).

This matters because forgetting is the one reason a tool can fix directly. A study of patients in Dublin (2011) found 55% preferred a text reminder, 19% a phone call and 19% an email. Most patients want to be reminded, and most no-shows happen precisely because nobody reminds them.

How automatic reminders reduce no-shows

The evidence is solid. In a randomized trial with 9,835 patients (American Journal of Medicine, 2010), the no-show rate fell from 23.1% without reminders to 17.3% with automated reminders, a 25% relative reduction. A review of 29 studies (Journal of Telemedicine and Telecare, 2011) found a 29% average reduction with automated reminders and 39% with manual phone calls. In ophthalmology, an observational study recorded a 38% reduction with SMS (BMC Ophthalmology, 2008).

On WhatsApp, the largest study to date (475,214 appointments, Buenos Aires, 2026) measured a 24% reduction with a single reminder sent about 24 hours before the visit. Timing matters more than quantity: one well-placed reminder captures most of the benefit.

Why online rescheduling also counts: when a patient can reschedule or cancel with one click (from the email link), a silent no-show becomes a cancellation the clinic can backfill. At a German ophthalmology practice (98,067 appointments, Frontiers in Digital Health, 2025), online bookings with self-cancellation had a 1.8% no-show rate versus 5.9% for offline bookings. Without that flexibility, the online rate was actually higher (14.3% vs 11.2%).

That is exactly the combination Veluni delivers: automatic email confirmation on every plan, automatic email and push reminders on the Elite plan, and a link in the confirmation email that lets the patient reschedule or cancel on their own, without calling the front desk.

Frequently asked questions

What is the average no-show rate for a clinic?

In the US, 15% to 30% (Annals of Family Medicine, 2024); well-run commercial practices report 5% to 7% (MGMA DataDive). If you do not measure yours, 15% is a safe starting estimate.

How do automatic reminders cut no-shows by 25% to 40%?

The range comes from peer-reviewed studies: a 25% relative reduction in a randomized trial (American Journal of Medicine, 2010), 29% with automated reminders in a review of 29 studies (Journal of Telemedicine and Telecare, 2011) and 38% with SMS (BMC Ophthalmology, 2008). The reminder fixes the main reason for no-shows, which is forgetting.

Do last-minute cancellations count as no-shows?

In this calculator, yes, if the cancellation is not rescheduled: the slot stays empty and the cost is the same. That is why the last-minute cancellation field is separate from the no-show field.

Does Veluni have automatic reminders?

Yes, on the Elite plan (US$ 179/month): automatic email and push reminders. Every plan sends an automatic email confirmation with the reschedule and cancel link.

Does this calculator use my data?

No. The calculation runs in your browser, nothing is sent to a server and no data is stored.
