How to calculate your no-show rate, and what to do with it
The no-show rate formula, the three mistakes that distort it, how to split it so it tells you something, and the fixes that match each pattern.
Frontiva · · 3 min read
Your no-show rate is the number of appointments where the customer did not arrive and did not cancel, divided by the number of appointments that were due to happen, over the same period. Count late cancellations separately. Then split the rate by service, day, time and booking source, because a single average hides the pattern that tells you what to fix.
The formula
No-show rate = no-shows ÷ (appointments that were still booked at their start time)
Use a month or more. A week is too noisy for most small businesses.
Three mistakes that distort it
Counting cancellations as no-shows. A customer who cancels the day before gave you a chance to refill the slot. Track late cancellations (inside your policy window) as their own number.
Dividing by everything ever booked. Appointments cancelled days ahead are not part of the risk. Divide by what was still on the calendar at start time.
Forgetting who did not get a reminder. If some customers never agreed to reminders, compare their rate with everyone else's. The difference is the value of reminders for your business.
Split it
A 9% average is not actionable. These splits usually are:
- By service. Long, expensive services and first visits often behave differently from routine ones.
- By day and time. Monday mornings and Friday afternoons have their own patterns.
- By booking source. Self-booked online, booked by phone, booked from a message.
- By lead time. Appointments booked weeks ahead no-show more than ones booked this week.
- By customer history. First-time customers versus regulars.
Match the fix to the pattern
| Pattern | Likely fix | |---|---| | High for first visits | A reminder the day before, plus clear directions and what to bring | | High for bookings made weeks ahead | A reminder closer to the date, and an easy way to reschedule | | High for one service | A deposit policy for that service only | | High on one day | Shorter booking windows or overbooking that day, carefully | | High for customers without reminders | Ask for reminder consent at every booking |
What a good rate looks like
It varies too much by industry to quote a number worth trusting. Compare against your own last quarter, not a benchmark from someone else's business.
Frequently asked questions
Should I charge no-show fees?
Only with a policy stated before booking. Our post on reducing no-shows with deposits covers the wording.
Do reminders really help?
Reminders with an easy way to reschedule are the most reliable fix. See reducing no-shows with appointment reminders.
How do I mark a no-show?
Your booking system should have a status for it. If it does not, keep a simple tally for a month; the rate is worth knowing even from a spreadsheet.
What Frontiva does here
Frontiva's bookings send 24-hour and 2-hour SMS reminders to customers who agreed and keep a full appointment history. Marking an appointment as a no-show is not built yet, which is also why the no-show recovery automation is listed as unavailable, so track the rate by hand for now. Analytics report appointments booked against the previous period.
