If the result is positive, it indicates growth.
If the result is negative, it indicates a decline.

Practical Examples
Example 1: Business Revenue Growth
- Old Value: $10,000
- New Value: $15,000
Calculation:
((15,000 – 10,000) / 10,000) × 100 = 50%
Result: 50% growth in revenue
Example 2: Population Decrease
- Old Value: 50,000
- New Value: 40,000
Calculation:
((40,000 – 50,000) / 50,000) × 100 = -20%
Result: 20% decrease in population
Example 3: Website Traffic Growth
- Old Value: 5,000 visitors
- New Value: 8,000 visitors
Calculation:
((8,000 – 5,000) / 5,000) × 100 = 60%
Result: 60% traffic growth
