Estimate operating room no show impact with inputs that match day-to-day operating room operations. The calculator keeps workload, available capacity, and operational assumptions visible, so you can test a baseline and then change one driver at a time. Results are planning estimates: use locally observed rates and apply clinical, labor, safety, and scheduling requirements before making an operational decision.
Missed visits = scheduled visits × no-show rate
Unfilled slots = missed visits × (1 − refill rate)
Lost contribution = unfilled slots × max(0, collected revenue − avoided variable cost)
The estimate isolates contribution lost from slots that stay empty after same-day recovery or wait-list fills.
Planning estimate only. Validate assumptions against local policy, staffing rules, equipment constraints, case mix, and patient-safety requirements.
For 120 scheduled visits at a 6% no-show rate, 7.2 are missed. After a 20% refill rate, 5.8 remain unfilled.
5.8 × ($1,800 − $350) = $8,352.00
No. It estimates lost contribution after avoided variable cost and recovered slots, not gross charges or total revenue.
Some costs are not incurred when a visit is missed. Subtracting them avoids treating gross collections as contribution.
Include them in the no-show rate only if they leave an unusable slot; use the refill input when the slot is recovered.
The calculator floors contribution at zero rather than reporting a negative loss per missed visit.
Use expected collected revenue for a completed visit, because billed charges may not reflect actual payment.
