1. What is Inflation Calculation?

Inflation is calculated using a weighted Consumer Price Index (CPI) basket that includes various goods and services. The CPI measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services.

\[ Inflation = \frac{Current\ CPI - Base\ CPI}{Base\ CPI} \times 100\% \]
