Class Capacity Utilisation Calculator

Work out class capacity utilisation instantly with clear inputs, formula shown and shareable results.

About Class Capacity Utilisation Calculator

Class utilisation is average attendance over capacity, and the empty places translate directly into foregone revenue because the instructor is paid whether the class is full or not. Consolidating two half-full classes is usually more profitable than filling both.

Formulas

Utilisation

Utilisation % = Average attendance / Class capacity x 100

Revenue foregone

Foregone = Empty places x Classes per week x Revenue per attendee

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What utilisation should I target?

70-85%. Above 90% regular members cannot get in, which is a churn risk; below 50% the timetable needs consolidating.

Should I cut poorly attended classes?

Look at who attends first. A quiet class that anchors a loyal member's routine may be worth keeping despite the utilisation figure.
