Questions about no-show cost
How do I calculate my no-show rate?
For one consistent period, divide appointments that were missed without enough notice by all scheduled appointments, then multiply by 100.
Why account for refilled slots?
A cancelled or missed slot does not create the full revenue loss when a waitlist, walk-in, or reschedule fills it. The refill input keeps the estimate from overstating the impact.
