No-Show Cost Calculator
This free No-Show Cost Calculator shows exactly how much revenue missed appointments cost you every month and year - and how much of it you could win back with automated reminders and confirmations.
TL;DR - The average business loses roughly one in four booked appointments to no-shows, at about $200 a pop. Enter your appointments, no-show rate, and average value to see your monthly and yearly cost - then see how much automated reminders (which cut no-shows by ~38%) could recover. Numbers are grounded in our appointment no-show statistics.

At a 20% no-show rate you lose 12 appointments a month. Automated reminders and confirmations cut no-shows by about 38% - which would bring your rate down to 12.4% and recover roughly $912 every month.
LeadResponse confirms and reminds every booked lead over Instagram DM - so more of them actually show up.

How the calculator works
1. Set your no-show rate
Drag the slider to the share of booked appointments that don't show up - or tap an industry preset if you're not sure of your exact rate.
2. Add your appointment numbers
How many appointments you book each month and what an average one is worth. These turn your rate into real dollars.
3. See what no-shows cost you
We show the revenue lost each month and year, plus how much automated reminders and confirmations could recover.
The data behind the numbers
No-shows are one of the largest silent drains on an appointment-based business - expensive, common, and almost entirely preventable. The research is consistent:
- The global average no-show rate is 23.5% - roughly one in four booked appointments - ranging from 5.5% at the best practices to 50%+ (Curogram).
- Each missed appointment costs an average of $200 or more once staff time, overhead, and opportunity cost are included (Artera).
- The average dental practice loses over $105,000 a year to no-shows; the average beauty salon loses about $67,000 (Arini AI, Bella Booking).
- 37.6% of no-shows happen simply because the client forgot - which means more than a third are preventable with a reminder (Curogram).
- Text-message reminders cut no-show rates by 38%, and multi-touch reminder sequences reduce them by 50-70% (Klara, Prospyr Med).
- Requiring a deposit reduces no-shows by 29-70%, and same-day appointments account for just 2% of no-shows (Shortcuts Software, Tebra).
This calculator multiplies your appointments by your no-show rate and average value to size the loss, then applies a 38% recovery rate for automated reminders - the figure from a medical-research study on text-message reminders, and the conservative end of the 50-70% range that multi-touch sequences reach.

Frequently Asked Questions
What is the average no-show rate by industry?+
No-show rates vary widely by specialty. The global healthcare average is 23.5%, with dentistry around 15%, beauty salons and spas typically 10-30%, dermatology and pediatrics near 30%, and sleep clinics highest at 39%. The best-run practices hold rates as low as 5.5%, while some clinics see 50% or more. Set the calculator to the benchmark closest to your business to estimate your own cost.
How much do no-shows cost a business?+
Each missed appointment costs an average of $200 or more once you count staff time, overhead, and the opportunity cost of turning others away. Across a year that compounds fast: the average dental practice loses over $105,000 to no-shows and the average beauty salon loses about $67,000. Enter your appointments, rate, and average ticket above to see your specific monthly and yearly cost.
Do appointment reminders actually reduce no-shows?+
Yes, and the effect is well documented. A study published in medical research found no-show rates were 38% lower among patients who received a text-message reminder than among those who did not - which is the recovery rate this calculator uses. Multi-touch sequences that reach out at 72 hours, 24 hours, and 2 hours before the appointment push that reduction to 50-70%.
How can I reduce my no-show rate?+
The proven levers are automated text reminders (down 38%), multi-touch reminder sequences (down 50-70%), two-way confirmation messaging (23% more effective than one-way), shorter booking windows (same-day appointments are just 2% of no-shows), and deposits (down 29-70%). The common thread is fast, automatic follow-up that keeps the appointment top of mind and secures a commitment.
Do deposits and confirmations help prevent no-shows?+
They do. Requiring a deposit has been shown to cut no-shows by 29-70% because a client with money on the line is far more motivated to show up. Two-way confirmation messages add a similar effect: when a client actively confirms, they make a micro-commitment that raises the odds they attend - and any cancellations surface early enough to refill the slot.
Is the No-Show Cost Calculator free?+
Yes. It is completely free, runs entirely in your browser, and requires no sign-up or email. Adjust the appointments, no-show rate, and average value as many times as you like.
