Frequently asked questions
How is the cost of a no-show calculated?
No-shows per month = your monthly bookings × your no-show rate. Multiply that by the average value of a booking to get the monthly loss, then by 12 for the annual figure. This calculator does exactly that with the numbers you enter.
What is an average no-show rate for appointments?
It varies widely by industry — many service businesses see 10–30% of booked appointments turn into no-shows, and it is higher for free-to-book slots with no reminder. Enter your own rate for an accurate figure; use 15–20% as a starting estimate if you don't track it yet.
How do I reduce no-shows?
The two biggest levers are taking payment upfront at the time of booking (a paid slot is rarely skipped) and sending automatic reminders — WhatsApp reminders in particular see 95%+ open rates in India. Book A Sloth does both out of the box.
