Example of CPI Calculation

1. Identify the Base Year CPI: Assume the CPI in 2019 was 250.
2. Current Year CPI: The CPI in 2021 is reported as 260.
3. Calculate the Percentage Increase:
\[
\text{Percentage Increase} = \left( \frac{\text{Current Year CPI} - \text{Base Year CPI}}{\text{Base Year CPI}} \right) \times 100
\]
\[
\text{Percentage Increase} = \left( \frac{260 - 250}{250} \right) \times 100 = 4\%
\]
This calculation indicates a 4% increase in the cost of living between 2019 and 2021.
