How break-even enrolment is calculated

Fixed costs ÷ contribution margin

Contribution margin per student = fee − variable cost (materials, variable utilities, payment gateway fees, etc.).

Break-even count = ceil(fixed costs ÷ margin). If margin ≤ 0, break-even is impossible at the given fee.

Source

breakEvenStudents = ceil(fixedCosts ÷ (feePerStudent − variableCostPerStudent)). Requires positive contribution margin. Standard managerial accounting model.

Frequently asked questions

What counts as fixed costs?

Rent, salaried core staff, annual licences — costs that do not change with one more student in the short run.

What about scholarships?

Use average realised fee, not headline fee, or raise variable cost to reflect average discount.

Is this the same as batch break-even?

Same formula — scope fixed costs to the batch/course you are analysing.

Why do I get an error?

If variable cost ≥ fee, each student loses money and no enrolment level covers fixed costs.
