About CPI

Consumer Price Index is an index which measures the weighted average of prices of a basket of consumer goods and services such as transportation, food and medical care.
It is calculated by measuring price changes for each item in the predetermined basket of goods and services and averaging them.

How does the Consumer Price Index help?

The Reserve Bank of India and other statistical agencies study CPI so as to understand the price change of various commodities and keep a tab on inflation.
CPI is also a helpful pointer in understanding the real value of wages, salaries and pensions, the purchasing power of a country’s currency, and regulating prices.
