A small worksheet for simultaneous booking capacity

Last materially reviewed 2026-09-23

Quick answerUse the worksheet to expose a bottleneck under explicit assumptions, not to predict a merchant scheduler or maximize utilization.
What to know

What the model calculates

The interactive worksheet uses identical appointments. Each needs one eligible staff member, one room and one equipment unit throughout the same occupied interval. Simultaneous capacity is the minimum of those three available counts. A separate cycle calculation adds service, preparation and reset minutes, then fits complete cycles into the entered working window. The resulting daily figure is a simple planning ceiling under synchronized starts, not a recommendation to fill every minute.

What to know

What it deliberately leaves out

The model does not include breaks, mixed services, variable travel, partial resource use, group attendance, late arrivals or demand. It cannot know whether staff are qualified or equipment is usable; you must enter the relevant available counts. It also does not connect to Trafft or any other booking product. A numerical answer therefore does not verify a product configuration, and a larger number does not mean that customers will actually book those appointments.

What to know

Read the example as an example

With three eligible staff, two rooms and one equipment unit, simultaneous capacity is one. If the service lasts forty minutes with ten minutes preparation and ten reset, a four-hour window contains four complete sixty-minute cycles under this model. The equipment is the binding constraint. Buying a second unit would change the arithmetic, but the worksheet does not evaluate whether that purchase is sensible, affordable or supported by actual demand.

What to know

Use the result to ask a better question

Compare the model with a hand-drawn schedule and investigate any difference. A difference may be caused by a legitimate staggered workflow or by an omitted constraint. Use the collision-test guide to translate the model into expected booking behavior. Inputs stay in the page and are not submitted or saved by this worksheet. Leave unknown inputs blank rather than substituting optimistic counts simply to obtain a more appealing capacity number.

Next: Model staff, rooms and equipment together

List the resources required by one appointment, then find which requirement limits simultaneous bookings.

Count the capacity.
Keep the assumptions.

Identical appointments, one person + one room + one item each, all occupied for the full cycle. No breaks, mixed services, travel or group attendance.

What this does not prove

This is an original planning aid, not a Trafft preview, live booking engine, purchase recommendation or demand forecast. It assumes synchronized full cycles and does not optimize a timetable. Reloading clears the inputs.
