No-Show Cost Calculator
Free no-show cost calculator for salons, beauty pros, therapists, and personal trainers. A no-show feels like an inconvenience — the numbers make it look different. See what empty slots are costing you per month, per quarter, and per year, and what automated reminders would change.
No-show cost calculator for service business owners — find out what empty slots are really costing you per month and per year
See your monthly and annual revenue lost to no-shows, the hours you're spending on prep that never gets used, and how much of that is recoverable with reminders.
Why no-shows hit harder than they look
A no-show isn't just one missed payment — it's a slot that can't be resold, an hour you've already prepared for, and a small dent in your week's predictability. Across a year, the numbers add up faster than most service businesses realise. Two no-shows a week at $130 each is $13,520 a year, plus the time you spent setting up, prepping, and waiting.
This calculator turns that drift into a number. You enter your typical session price, the number of slots that go unfilled in a week, and the calculator does the rest — including a rough estimate of the wasted prep time at your real hourly rate. It's the same maths a deposit policy or a reminder system pays back against.
In an NHS trial, a clearer reminder message cut missed appointments from 11.1% to 8.4%. The calculator below shows what your specific number looks like — and how much of it is recoverable.

How to calculate your no-show rate
Your no-show rate is the share of booked appointments where the client did not turn up. Count a month, so one quiet week does not skew it.
No-show rate = no-shows ÷ booked appointments × 100
For example, say you booked 120 appointments last month and 6 clients did not arrive. That is 6 ÷ 120 × 100, a no-show rate of 5%. Late cancellations you could not refill cost the same slot, so many owners count those too. Then use the rate with your session price in the calculator above.
Common questions
How is the cost of a no-show calculated?
It is the price of the missed appointment plus the time you have already invested — preparation, setup, waiting. Multiplied across a year of weekly no-shows, even one or two a week becomes a four- or five-figure number for most solo service businesses.
What's a typical no-show rate for a service business?
Anywhere from 3% to 15% of appointments depending on the industry. Beauty and wellness tend to sit in the 5-10% range without a deposit policy, and drop sharply once one is in place. Therapy and counselling sit a little lower, and personal trainers somewhere in the middle.
How much can reminders actually reduce no-shows?
The best-measured evidence comes from healthcare. In an NHS trial with the Behavioural Insights Team, a clearer reminder text cut missed appointments from 11.1% to 8.4%. That is about a quarter fewer no-shows. Your own result will depend on your clients and your policy.
