About Retail Inflation
- Retail inflation, also known as Consumer Price Index (CPI) inflation, tracks the change in retail prices of goods and services which households purchase for their daily consumption.
- CPI is calculated for a fixed basket of goods and services that may or may not be altered by the government from time to time.
- The change in the price index over a period of time is referred to as CPI-based inflation, or retail inflation.
- What Does the CPI tell? Following are a few things that the CPI index interprets:
- Cost of living
- The purchasing power of consumers
- The expensiveness of different articles that consumers buy and services that are availed
- Value of the Indian rupee
- How is CPI calculated?
- CPI is calculated as a percentage. It is a comparison of the general price level in the markets in a particular time period from a time frame in the past. This is known as the base year.
- CPI, therefore, is calculated by referring to a base year, which is a benchmark. Currently, the base year is 2012.
- The formula for calculating the CPI index is:
- CPI = (Cost of a Fixed Basket of Goods and Services in the Current Year/Cost of a Fixed Basket of Goods and Services in the Base Year) * 100
- The National Statistical Office (NSO), Ministry of Statistics and Programme Implementation (MoSPI), compiles All India as well as state-wise CPI for Rural, Urban, Combined sectors and releases the CPI numbers every month.
- How is the Consumer Price Index (CPI) Used?
- It is used as a macroeconomic indicator of inflation, as a tool by the central bank and government for inflation targeting and for inspecting price stability, and as a deflator in the national accounts.
- CPI also helps understand the real value of salaries, wages, and pensions, the purchasing power of the nation’s currency, and regulating rates.
