Your numbers
Costs that don't change with enrollment: rent, admin salaries, insurance, base operations.
Annual tuition, or your state's per-pupil funding.
The added cost of each student: curriculum, supplies, incremental staffing.
Max students your facility holds — shows break-even as a share of capacity.

How it's calculated
Break-even enrollment = fixed costs ÷ (revenue per student − variable cost per student). The denominator is your contribution margin per student - what each student adds toward fixed costs after covering their own variable cost.

How to use this calculator
- 1
Enter your fixed costs
Add the annual costs that don't change with enrollment - rent, admin salaries, insurance, and base operations.
- 2
Enter revenue per student
Your annual tuition, or your state's per-pupil funding for a charter.
- 3
Enter variable cost per student
The added cost of each student - curriculum, supplies, and incremental staffing.
- 4
Read your break-even
The calculator divides fixed costs by the per-student contribution margin to show the minimum enrollment that covers your costs - and, if you add capacity, how much cushion you have.
Frequently asked questions
How do you calculate break-even enrollment?
Break-even enrollment = fixed costs ÷ (revenue per student − variable cost per student). The denominator is your contribution margin per student - what each student contributes toward fixed costs after their own variable cost.
What is a healthy break-even relative to capacity?
Breaking even at 40% of capacity is a strong margin of safety; around 70% is manageable with solid enrollment marketing; 90%+ is tight - a small shortfall could mean operating at a loss.
Why can't I break even in the calculator?
If your variable cost per student is equal to or higher than your revenue per student, each additional student loses money, so there's no enrollment that covers fixed costs. Raise revenue per student or cut variable cost per student.
