Frequently asked questions
How is it calculated?
Bookings per week × no-show rate × guests per booking × revenue per guest. Year = weekly value × open weeks per year, month = yearly value ÷ 12.
What does “avoidable” mean?
It is an assumption you set yourself: which share of no-shows reminders and easy cancellation links can prevent. It is not a promise.
Are my numbers stored?
No. The calculation runs entirely in your browser; nothing is sent.
