Preguntas frecuentes
¿Cómo se calcula el cambio porcentual?
Resta el valor inicial del valor final, divide el resultado entre el valor absoluto del valor inicial y multiplica por 100: Cambio (%) = ((Nuevo − Anterior) ÷ |Anterior|) × 100.
¿Puede ser negativo el cambio porcentual?
Sí. Si el valor nuevo es menor que el anterior, la diferencia es negativa, lo que indica una disminución porcentual. Por ejemplo, de 100 a 80 es un cambio de −20%.
¿Qué pasa si el valor inicial es cero?
El cambio porcentual desde cero es matemáticamente indefinido porque la división por cero no es posible.
