What is Consumer Price Index (CPI)?

CPI stands for consumer price index which is an index of inflation calculated based on the price changes of everyday products that people purchase. It measures a ‘basket’ of goods and services including food, transport, health, and education at the retail level. The Consumer Price Index India is viewed as an important economic measure to trace changes in the cost of living and changes in the levels of inflation throughout the nation. This blog will cover what is consumer price index, the formula applied in calculating it, and why it even matters. We will also cover the different types of CPI and their distinct applications. 

Types of Consumer Price Index

The Consumer Price Index is one of the means to measure inflation since it reflects changes in the prices of a fixed basket of goods and services over time. There are two major types of CPI indexes published by the Bureau of Labor Statistics every month for the US: 

• Consumer Price Index for All Urban Consumers (CPI-U): The index is for 93 percent of the U.S. population, and covers urban district areas, excluding the most remote rural areas. This index accounts for households that do not live on farms, in institutions, or on military bases. The CPI-U is the primary series for measuring the overall economy's inflation rate for financial markets. 
• Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W): The index covers 29% of the United States population, targeting households whose income comes mostly from clerical and wage jobs. This index serves as a base for the adjustment of Social Security benefits, federal pensions, and income tax brackets to keep such adjustments in line with the living costs and to avoid increases in taxes due to inflation. 

Both the CPI-U and the CPI-W are of central importance in the reckoning of inflation and in making informed decisions economically.

How is CPI Calculated in India?

The Consumer Price Index formula is used to calculate this index by comparing the current cost of a fixed basket of goods and services to the cost in a base year. In simple words, the Consumer Price Index finds out how prices of goods and services change over time in India.  

Annual CPI = (Value of basket in the current year/ Value of basket in the base year ) ×100

For instance, if the basket costs ₹1,200 in the current year and ₹1,000 in the base year:

Annual CPI = (1200/1000)×100=120

The CPI of 120 indicates a 20% increase in prices compared to the base year.

Here is an example: 

If the CPI this year is 125 and last year it was 120:

Inflation Rate = (125−120/120) × 100

This indicates a 4.17% inflation rate over the year.

By using these formulas, one can measure inflation to understand how price changes affect the cost of living for consumers.

How is the Consumer Price Index (CPI) Used?

The CPI is an informative tool used in many ways. Those who work in financial markets use the CPI to find out exactly how prices change with time, thus enabling them to make well-informed investment decisions.

For example, companies may use the index to set up the prices for their products or services, whereas consumers can use it to budget their spending or negotiate salary. Because the CPI is a reflection of changes in the cost of living, this would be an important index for estimating reasonable wages and ensuring increases in people's earnings along with inflation. Researchers often use the consumer price index table to compare historical data and evaluate how inflation has impacted different sectors of the economy.
