Example of Index Calculation
Let’s understand how the tool works with a real-life example.
Example 1: Stock Market Index
- Base Value: 200
- Current Value: 300
- Multiplier: 100
Formula:
Index = (300 ÷ 200) × 100
Index = 1.5 × 100
Index = 150
Result:
The index value is 150, meaning the value has increased by 50% compared to the base.
Example 2: Business Growth Analysis
- Base Revenue: 5000
- Current Revenue: 7500
- Multiplier: 100
Index = (7500 ÷ 5000) × 100
Index = 150
