How do you calculate no-show rate?
No-show rate is the number of missed appointments divided by the number of appointments booked, multiplied by 100. A sales team that booked 80 appointments and had 24 people fail to attend has a no-show rate of 30%.
Appointments that were cancelled or moved in advance are usually left out of the missed count, because the slot could be offered to someone else.
What is show rate?
Show rate is the share of booked appointments that were attended, which makes it the no-show rate subtracted from 100. The example above has a show rate of 70%.
Appointment-setting agencies tend to quote show rate, and clinics and service businesses tend to quote no-show rate. The tool works as a show rate calculator as well, since both figures appear in the results.
What do missed appointments cost?
Missed appointments cost you the value of each appointment multiplied by the number missed, and the ad spend that produced them is already gone. At 450 per attended appointment, 24 no-shows in a month represent 10,800 of lost value.
The cost is sharper for an agency paid per appointment that shows. Every no-show is a lead the agency bought, qualified and booked without being paid. Put a price on that lead with the cost per lead calculator.
How do you reduce no-shows?
You reduce no shows by booking people who mean to attend, confirming the right phone number and reminding them before the appointment. The first two are decided on the form, before the booking exists.
A Growform form asks about the project and the timing first, so a booking reflects a real need. Phone validation checks the number while the lead is still on the form, which means your reminders have somewhere to go. For the reminders themselves, the appointment reminder text generator writes a confirmation, two reminders and a follow-up for anyone who misses the slot.
How to use the no-show rate calculator
Enter missed appointments
Count the people who did not attend. Leave out anyone who cancelled or rescheduled ahead of time.
Add a value and a target
The value shows what no-shows cost you. The target shows what a better rate would be worth each month.
How Growform improves your show rate
People keep appointments they asked for with accurate details. The form is where both are settled.
- Bookings come from people with a real need.
Qualifying questions come before the contact step, so the lead has described the job before booking.
- Phone numbers are checked before the form is sent.
Every phone field checks the format for its country, and Twilio Lookup can validate the number in real time.
- The thank-you screen sets expectations.
A custom ending can confirm what happens next, show a short video and link to your booking page.
- Your calendar tool receives the lead at once.
A webhook or Zapier passes the lead to GoHighLevel or your scheduling software, where reminders begin.
Frequently asked questions
Should cancellations count as no-shows?
Most teams count them separately. A cancellation gives you notice, and a no-show leaves the slot empty with no chance to fill it.
How often should I measure no-show rate?
Measure it monthly, and weekly while you are testing a change such as a new reminder. Use the same definition of a missed appointment each time.
Does asking more questions lower the number of bookings?
A few short questions spread across steps feel lighter than one long page. The bookings you do receive come from people who have told you what they need.
What is a good show rate for booked sales calls?
The right figure depends on how the appointment was booked and how far ahead. Track your own rate, set a target a few points better, and use the calculator to see what reaching it would return.
Why this tool is different
The calculator measures no-shows in money as well as in percentages.
- Booked and missed appointments are the only required fields, and the ring shows the share that attended.
- The value of an attended appointment turns missed slots into lost revenue for the month.
- A target rate shows the appointments and revenue a lower no-show rate would return, so a reminder sequence can be justified with a figure.
