How to Calculate Classroom Utilization in 3 Steps

Follow these steps to get results in under a minute

01
Add your campus rooms
Enter each room's name, type (lecture room, lab, auditorium, etc.), seating capacity, and total hours it is available per week. Available hours typically reflect your institution's operating hours multiplied by weekdays.
02
Enter scheduled hours per room
Input how many hours per week each room is actually booked for scheduled sessions — lectures, labs, tutorials, or exams. The tool computes utilization as scheduled hours divided by available hours.
03
Review bottlenecks and export
Rooms above 85% utilization are flagged as bottlenecks; below 40% are flagged as under-utilized. The colour-coded report identifies where space investment or timetable redistribution is needed. Export a PDF for estates management.

"We have over 80 rooms across four buildings. This tool helped us identify that our science labs were at 92% utilization while three seminar rooms across the road were barely at 30%. That insight alone justified a timetable restructure."

"Before I had to compile utilization manually from the timetabling system. Now I enter the weekly totals here and get an instant visual report I can share with the Dean before the next semester begins."

"The bottleneck flag at 85% is particularly useful. We used to only look at overall occupancy rates, but this showed us individual rooms creating scheduling conflicts for the engineering faculty."

"The PDF output is exactly what our accreditation reviewers ask for — a clear table of space utilization with capacity and hours data. We now run this every semester end."
