Office Hours Capacity Calculator
Estimate appointment capacity from instructors, available minutes, meeting length, and reset time between students.

Protect usable appointment time
- Count simultaneous instructors.
- Protect nonappointment duties.
- Combine session and reset time.
- Compare capacity with actual demand.
Transition time protects the next meeting
Notes, privacy, file opening, and a short overrun can make back-to-back 15-minute slots unrealistic.
A reset allowance keeps those minutes visible rather than stealing them repeatedly from later students.
Fitting appointments into two hours
Two instructors each offering 120 minutes can fit six 18-minute appointment blocks, for 12 students total. Demand from 18 students exceeds that capacity by six.
Capacity does not measure access quality
Demand may cluster around deadlines or conflict with student schedules. Drop-in and booked formats also use time differently.
A shortfall can prompt another window, group support, or triage rather than simply shorter conversations.
Support demand may also understand workload that may drive support demand or plan another sequence of timed student slots.
Working through the denominator
Scope: Each appointment consumes one full session-plus-reset block; unused fragments do not become partial appointments.
Track demand and service separately
Record requested, booked, attended, cancelled, and unserved appointments. Capacity utilization based only on bookings can conceal no-shows or unmet demand.
If shortfall repeats, compare another window, group session, asynchronous response, or additional instructor. Do not shrink appointments below the time needed for useful support merely to improve the capacity number.
Appointment demand is not uniform through the term. Measure ordinary weeks and deadline peaks separately before deciding that a low average utilization means the service is oversized.
Accessibility accommodations, interpretation, sensitive concerns, or complex feedback may require longer slots. Reserve an appropriate appointment type rather than forcing every request into the same duration.
When students book but do not attend, record no-shows separately from unserved demand; the remedies are different.
For drop-in hours, average meeting length can estimate throughput but cannot guarantee a queue length. Arrival patterns matter: ten students arriving together experience waiting even when total capacity across the window is adequate.
Privacy and room availability may also limit the number of instructors who can work simultaneously, even when staff time exists.
Questions that affect interpretation
Why is leftover time ignored?
A fragment shorter than one full session-plus-reset block cannot support another standard appointment.
Can group office hours increase capacity?
Yes, but group support is a different service model and should be planned separately.
What if no students request meetings?
Utilization is zero while the calculated appointment capacity remains available.
