Calculadora de Tasa de Retención Escolar — Fórmula
## How School Retention Rate is Calculated
Retention rate measures the proportion of non-graduating students who return the following year.
### Formula
**Retention Rate = Returning Students / (Start Enrollment - Graduates) x 100**
**Attrition Rate = 1 - Retention Rate**
High retention (above 90%) indicates student and family satisfaction. Attrition drives enrollment decline and budget instability.

Ejemplo Resuelto
500 students at start, 25 graduates, 460 return next year.
- Eligible to return: 500 - 25 = 475
- Retention rate: 460 / 475 x 100 = 96.8%
- Attrition: 475 - 460 = 15 students lost
- Attrition rate: 3.2%
