Formula & Methodology
The IPI is calculated using the following formula:
IPI = [(Current Year's Index / Base Year's Index) * 100 - 100] * (Base Year's Value / Current Year's Value)
Real-World Examples
Example 1
Base Year: 2010, Index: 100, Current Year: 2020, Index: 120
IPI = [(120 / 100) * 100 – 100] * (100 / 120) = 8.33%
Example 2
Base Year: 2015, Index: 110, Current Year: 2022, Index: 130
IPI = [(130 / 110) * 100 – 100] * (110 / 130) = 15.38%
