How This No-Show Calculator Works
This calculator uses a simple business model: your weekly appointment volume, your current no-show rate, and your average appointment value. It then projects annual losses over 50 working weeks so you can quickly understand the size of the problem.
The savings estimate assumes reminder workflows can recover a large share of avoidable missed appointments. That percentage varies by industry, but the goal here is to give you a practical decision number to guide next steps.
What Is an Appointment No-Show and Why Does It Happen?
An appointment no-show happens when a client or patient does not attend a scheduled booking and does not cancel in time. For appointment businesses, that creates an empty slot that staff still had to prepare for.
The most common reasons are simple: people forget, plans change at the last minute, or rescheduling feels inconvenient. That is why reminder systems that include fast confirmation or reschedule options often outperform reminder-only flows.
How to calculate your no-show rate
Your no-show rate is the share of booked appointments that were neither attended nor cancelled in time. Pick a period (one month is enough), count the appointments you scheduled and the ones that were missed without notice, then:
Worked example: a salon schedules 160 appointments in a month and 22 clients neither turn up nor cancel in time. 22 ÷ 160 × 100 = 13.75, so the no-show rate is about 14%. Put 14% into the slider above to see what that costs over a year.
What to count: an appointment is a no-show when the client did not attend and did not cancel before your notice deadline. Track late cancellations you could not refill as a separate late-cancellation rate; if you mix them into the no-show rate, the number stops being comparable from month to month.
What is a good no-show rate? There is no single target. Across 105 published studies of appointment scheduling, the average no-show rate was around 23% (Dantas et al., Health Policy, 2018), and a twelve-year study of ten US clinics measured 18.8% (Kheirkhah et al., BMC Health Services Research, 2016). Compare your rate with your own previous months first; sectors differ too much for one benchmark to fit everyone.
How to Calculate Your No-Show Cost
The formula is straightforward:
For example, a salon with 25 weekly appointments, a 15% no-show rate, and an average price of A$65 loses approximately A$12,188 per year. That is money that was never earned, staff time that was wasted, and opportunity cost from clients who could have filled those slots.
No-Show Rates by Industry
| Industry | Avg. No-Show Rate |
|---|---|
| Hair Salon / Barber | 15% |
| Beauty & Nails | 14% |
| Dental Practice | 12% |
| Medical / Clinic | 18% |
| Gym / Personal Trainer | 20% |
| Spa / Wellness | 13% |
| Tutor / Coach | 16% |
| Consulting | 10% |
Text reminders raise attendance; a Cochrane review of SMS reminders found the effect comparable to phone-call reminders (Gurol-Urganci et al., 2013). How far your own rate falls depends on why clients miss appointments, so model it with the recovery-rate control above rather than a fixed benchmark.

5 Proven Strategies to Reduce No-Shows
Send SMS appointment reminders
A Cochrane review found SMS reminders increase attendance compared with no reminder (Gurol-Urganci et al., 2013). A well-timed SMS 24 hours before the appointment is the highest-impact step for most businesses. You can use automatic SMS appointment reminders with Etisia to automate this from your Google Calendar.
Offer easy rescheduling
When clients can cancel early and reach you through a clear call or booking path, they are far less likely to simply disappear. Make it frictionless.
Implement a cancellation policy
A transparent policy communicated at booking time encourages clients to cancel ahead of time rather than not showing up.
Send confirmation at booking
An immediate booking confirmation SMS locks the appointment in the client's mind and gives them a reference to check later.
Build a waitlist system
When a cancellation does happen, a waitlist lets you fill that slot quickly, turning a loss into revenue.
Why SMS Reminders Outperform Email and Phone Calls
Email reminders often get buried in crowded inboxes, and manual call reminders consume staff time. SMS tends to be faster to notice and easier to act on, especially when the message includes a clear cancellation path or phone number.
In practice, the winning setup is consistency: automatic reminders, clear timing, and low-friction next steps for clients. That is usually what moves missed appointment rates down month over month.
