Does a class cover
its costs in reality?

Calculate contribution, practical break-even attendance and required occupancy from your attributed revenue and costs. The result describes a typical class, not studio profit.

01

Attribute

Revenue and costs on a consistent basis.

02

Calculate

Contribution, occupancy and break-even attendance.

03

Interpret

Using the method and its limitations.

Mathematical break-even attendance = attributed fixed costs ÷ (attributable revenue per attendance − variable cost per attendance). Practical break-even attendance is rounded up to the next whole place.

Non-contractual educational result. Contribution does not mean net profit, available cash or ROI. The monthly projection models neither seasonality nor changes in demand.

Contribution.
Not net profit.

The calculation isolates a typical class. It does not replace an income statement, a cash-flow budget or a complete studio analysis.

  1. 01
    Allocation changes the result

    Packs and subscriptions require a consistent revenue allocation convention.

  2. 02
    Break-even remains conditional

    It depends on the costs and revenue entered, not on guaranteed demand.

  3. 03
    The month is only a multiplication

    The projection models neither seasonality nor changes in behaviour.

  4. 04
    Capacity can make break-even impossible

    If break-even attendance exceeds available places, the business model must be reviewed.

Straight answers

Frequently asked questions

What is the difference between revenue, contribution and profit?

Revenue is the amount attributed to attendance. Contribution deducts the costs attributed to the class. Net profit requires all studio expenses, financing, taxes and other accounting items; this tool does not calculate it.

How should I account for a credit pack or subscription?

Use a documented, consistent revenue allocation rule. The face value of a pack or subscription does not automatically correspond to the revenue attributable to one attendance.

Does the break-even threshold guarantee a profitable time slot?

No. Break-even attendance is a conditional result based on the revenue, costs and attendance entered. It guarantees neither demand, attendance nor stable costs.

Is the data I enter transmitted?

No. The calculation runs in your browser. The values you enter are neither sent to GE2studio nor stored by the calculator.
