Diferencia porcentual
Compara dos valores de forma simétrica
Result = (|V1 - V2| / ((V1 + V2) / 2)) * 100 Sin cálculos aún.
Cómo calcular
Result = (|V1 − V2| ÷ ((V1 + V2) ÷ 2)) × 100
The formula calculates the absolute difference between two numbers |V1 - V2| as the numerator. The denominator is the average of the two numbers, calculated as (V1 + V2) ÷ 2. Dividing the absolute difference by the average and multiplying by 100 yields the percentage difference.
* Ejemplo: 40 vs 60 → 40% difference

Diferencia porcentualEjemplos resueltos
Cómo funciona
Percentage difference measures the relative discrepancy between two numbers when neither number is designated as the 'original' or 'baseline' starting point. Unlike percentage change, which assumes a time-based direction from old to new, percentage difference compares two independent measurements neutrally by dividing by their average value.

Preguntas frecuentes
When should I use percentage difference instead of percentage change?
Use percentage difference when comparing two static numbers where neither number represents a starting 'before' or 'after' state. If you are tracking progress over time, use percentage change.
Why does the formula divide by the average of the two numbers?
Dividing by the average ensures symmetry. It guarantees that comparing Value A to Value B produces the exact same percentage difference as comparing Value B to Value A.
Can percentage difference be negative?
No, percentage difference is always a positive number because the numerator uses absolute value (|V1 - V2|).
