Différence en pourcentage
Comparez deux valeurs (approche symétrique)
Result = (|V1 - V2| / ((V1 + V2) / 2)) * 100 Aucun calcul pour le moment.
Comment calculer
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.
* Exemple: 40 vs 60 → 40% difference

Comment ça marche
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.

Foire aux questions
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|).
