Understanding Class Fill Rate
How we calculate. Fill % = enrolled seats ÷ capacity × 100. See our methodology and accuracy policy .
Real-world scenario: A typical Class Fill Rate case uses enrolled 28 and capacity 30. Enter the same figures below to reproduce the worked path.
What is Class Fill Rate?
Scheduling and resource KPI. Over-enrollment above 100% may be allowed with overrides—policy dependent.
- Capacity = max seats
- Enrolled = current headcount
- Waitlists are separate
The Formula
Worked Example
Common Use Cases
- Registrar scheduling: section viability
- Department planning: add/cancel sections
- Classroom utilization: seat use
Pro Tips
- Track low-fill early
- Compare online vs in-person
- Don’t ignore pedagogy caps
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |
| Percent change | Comparing old vs new values |
Limitations: Class Fill Rate results are educational institutional planning aids—not accreditation determinations or financial-aid advice. Confirm measure specs with your registrar and IR office.

- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
