## How Per-Pupil Spending is Calculated
Per-pupil expenditure (PPE) is a key metric for comparing educational investment across schools and districts.
### Formula
**PPE = Total Budget / Total Enrollment**
**Instructional PPE = Budget x Instructional % / Enrollment**
### Context
- U.S. national average: approximately $14,000 per pupil
- Range varies enormously: from under $8,000 to over $25,000 per pupil
- Higher spending does not always mean better outcomes, but chronic underfunding correlates with lower achievement.

Exemplo Resolvido
A school with an $8M budget, 600 students, and 65% instructional spending.
- Per-pupil: $8,000,000 / 600 = $13,333
- Instructional: $8,000,000 x 0.65 / 600 = $8,667
- Non-instructional: $8,000,000 x 0.35 / 600 = $4,667
