One client not turning up is annoying, and then you get on with your day. It's the steady trickle that hurts. A couple a month, a few late cancellations you couldn't fill, and by the end of the year it can easily be thousands of dollars. Put your own figures in below and see. It also shows what reminders could save, which is the one fix with strong research behind it.
The opportunity cost of an empty slot
When someone doesn't show, the whole price of that appointment is gone. You'll save a bit on product, maybe. The rest carries on regardless (the chair or room rent, your time) and if you're mobile you've usually done the drive before you find out nobody's home.
Late cancellations are the same story unless you can fill the gap. Plenty of notice changes things, because you can usually offer the time to someone else. Which is why anything that turns a no-show into an early cancellation is worth having, even if that client never rebooks.
Pick your main service below (it fills in a typical Auckland price to start you off) and change the numbers to yours. It updates as you go.
Your appointments
Missed appointments in a typical month
These start as an example, not an average. Finding your own numbers explains why, and how to count yours. An unfilled cancellation is one that came too late for you to fill the time.
The reminder saving assumes you don't send reminders yet. If you do, their effect is already in your numbers. This is an estimate to help you decide, not financial advice.
How this is worked out
- Each no-show or unfilled cancellation costs its full price. Rent, your time and any travel are spent whether or not the client comes. You might save a little on products, but it's a small part of the price, so it isn't counted.
- A year is 12 of your typical months. If you take long breaks, the yearly figures will be a little high.
- Reminders cut no-shows by 25%, the pooled result of 16 randomised comparisons in healthcare, with a likely range of 18% to 32%. Clients who are reminded are assumed to turn up; some will cancel or move instead, so the real saving may be a little lower. Reminders aren't assumed to change cancellations.
- Starting prices are the Auckland figures from our pay calculator, and change with your service. The missed-appointment figures are only an example.
- GST: if you're registered, 3/23 of what clients pay is GST, so your real loss is a little lower than shown.
What the research says about reminders
The research behind this guide comes mostly from healthcare, where missed appointments have been studied for decades. We couldn't find any independent research on beauty or massage appointments, so we've said where each figure comes from and how far it's likely to carry over.
Of all the fixes for missed appointments, reminders are the one that's been studied most, and the evidence for them is good.
Text reminders get more people through the door. A Cochrane review of healthcare trials found they raised attendance compared with no reminder at all, and did about as well as a phone call for less effort. Across the trials, 78.6% of people who got a text turned up, against 67.8% of those who didn't. The reviewers rated that evidence moderate quality (Cochrane).
The 25% used above comes from a 2016 review that pooled 16 randomised comparisons counting no-shows specifically. With a text reminder, people were about 25% less likely to miss without cancelling, most likely somewhere between 18% and 32% (BMJ Open). The same review found a second reminder lifted attendance a little more, though it made no clear difference to no-shows.
How you word it seems to matter. Two NHS trials, about 20,000 hospital appointments between them, tried a reminder that spelled out what a missed appointment cost the health service, and missed appointments fell from 11.1% to 8.4% compared with the hospital's usual message. A vaguer version that only said not attending "wastes NHS money" didn't do as well (PLOS ONE).
Would that work for a small business? No one's tested it, and it could easily come across as a telling-off. The researchers' own advice was to keep reminders specific, which for you just means the day, the time, where, and an easy way to reply if something's changed. Most of the trials sent theirs within three days of the appointment. If you'd like wording to start from, our cancellation policy guide has confirmation and reminder messages you can fill in and copy.
Healthcare isn't hairdressing, of course. Patients don't always get to pick their appointment; your clients chose theirs, so they may be keener to keep it. Still, plain forgetting is one of the most common reasons people give for missing one (Cochrane), and forgetting is exactly what a reminder fixes. So take the saving above as a fair guide rather than a promise.
Deposits and fees
There's far less research on deposits. A 2023 review of 61 studies into cutting missed healthcare appointments found just two that tried money at all, one reward and one fine (BMC Health Services Research). We couldn't find a single independent study of whether deposits get people to turn up. A few booking software companies say they do. They also sell deposit features, and the ones we found don't say how they measured it.
That's why deposits are left out of the figures above. A deposit does cover some of your loss when someone doesn't come; it just isn't shown to stop the no-show happening.
Fines after the fact don't look promising either. A Danish trial of 6,746 hospital appointments told patients they'd be fined about €34 if they didn't turn up, and it made no difference: about 5% missed either way. By the end of the study only 27 of the 130 fines had been paid, and that was after up to two reminder letters (BMJ Open).
A public hospital isn't a business with regulars, mind you, and a client who wants to keep their spot with you may well pay up. But a fee you can't collect doesn't cover anything. A deposit taken when the client books is usually the more practical option, and our cancellation policy guide goes into how much is fair to ask and what New Zealand law expects.
Refilling late cancellations
The cheapest fix for a late cancellation is someone else in the chair. Keep a short list of regulars who'd happily come in earlier, or put up a quick post on your socials, and a gap can turn back into a paid appointment without anyone being charged a cent.
Reminders help with this as well. They prompt people to cancel rather than just not show, and a cancellation the day before is a lot easier to fill than a gap you only discover when nobody walks in.
It's harder when you're mobile, because whoever takes the slot has to be free and close by. Grouping bookings by area gives you a better chance of someone nearby squeezing in.
Finding your own numbers
The result's only as good as what you put in. Most booking apps keep track of no-shows and cancellations, so it's worth looking back over the last three months; if it's a paper diary or your phone calendar, count the gaps. Three months will tell you more than one bad week.
We don't know of any reliable figures for how often beauty and massage clients miss appointments. The ones online come from booking software companies' blogs, and they sell the fix and don't say how they counted. So the figures above start with an example, 2 no-shows and 2 unfilled cancellations a month, not an "average".
If you're happy to share yours anonymously, send them to hello@booknatty.com. With enough of them we could publish real numbers for Auckland.
Natty will send reminders for you. We're building Natty, an Auckland booking service for independent professionals, and once it's live it'll remind your clients about their bookings (and hold a card to secure each booking). If that sounds useful, register your interest.
