How is CPI Used: Meaning, Working and Process
How Is CPI Used?
The type of calculation involved during the estimation of CPI is quite complicated. Different categories and sub-categories are made to segregate the consumption items based on consumer groups, including urban and rural inhabitants. The national statistical organisations compute the final overall price index based on these indices and sub-indices.
In recent times, CPI has become the most prevalent method to analyse price inflation and is applied as a macroeconomic indicator by the Indian Government and the Reserve Bank of India (RBI). They use CPI to determine price inflation and plan their economic rules and strategies accordingly.
Which Agencies Uses CPI to Take Economic Decisions?
Mentioned below is the list of eight agencies that use the Consumer Price Index (CPI) to predict inflation and take economic decisions:
- Attire
- Food and Drink
- Housing
- Education
- Healthcare
- Transportation
- Communication
- Leisure
If you are wondering how CPI works, look at the easy steps to calculate the consumer price index.
What Is the Step-by-Step Process to Calculate the Consumer Price Index (CPI)?
Step 1: Gather Prices for Certain Products and Services from the Past
First, conduct thorough research online on the prices of some products and services from last year. Also, collect information from their bills and receipts for purchases made earlier. Also, make sure that you gather information about their demand in the preceding year.Step 2: Gather Prices for Current Products and Services
After collecting information about the demand and prices of certain goods and services from last year, carry out the same procedure for the current year. Also, if necessary, check the prices of the goods from similar brands to make a better comparison.Step 3: Sum Up All Prices Together
After this, add all the prices of previous goods and services and jot down those numerals. In the same way, add all the prices of products bought in the current year.Step 4: Divide Total Present Product Price by Total Past Product Price
After jotting down the addition of the entire goods price from the preceding and prevailing year, divide the total current product price by the total past product price.Step 5: Multiply the result by 100
Once you get the values from the last step, multiply the numeral by 100 to get the exact Consumer Price Index (CPI).
To get a better elaboration, check out the formula to calculate the CPI in an economy.
Consumer Price Index (CPI) = (Cost of Fixed Basket of Goods and Services in Current Year/Cost of Fixed Basket of Goods and Services in Base Year) X 100.
Remember that this formula only applies to figure out the inflation rate once you have computed the Consumer Price Index for two years.
An Example Showing the Computation of Consumer Price Index (CPI)
The formula to calculate Consumer Price Index in an economy is:
CPI = Cost of market basket in the current year/Cost of market basket in the base year X 100
Suppose that the cost of market basket in the present year is ₹11.50 and cost of market basket in the base year is ₹8.75.
Then, the equation will stand at ₹11.50 / ₹8.75 = 1.32
After this, multiply this number by 100, which will be 1.32 X 100 = 132
Now, deduct this numeral from 100 in order to get the final percentage of change, i.e. 32%.
Thus, there is total 32% change in product prices since the base year.
What Are the Uses of Consumer Price Index (CPI)?
To Measuring Inflation
Inflation signifies an escalation in prices which causes adverse effects on purchasing power of individuals. With a price increase, your money cannot do much since you must pay more while buying your desired product or service. CPI helps to point out the level of inflation within an economy alongside their current trending, consumer behaviour, the average change in the price of goods over time, etc.To Measure Deflation
Unlike inflation, CPI also helps measure deflation, which also affects a country's economy. During this phase, the costs of products and services fall significantly, and inflation goes below 0%. As a result, the purchasing capacity of consumers starts to upsurge, and the supply of money starts to fall.To Adjust Cost-of-Living
The Consumer Price Index (CPI) also helps adjust Cost-of-Living. This cost of living index comprises food, shelter, energy, healthcare, transportation, clothing, childcare, and more. The cost-of-living index helps determine Social Security benefit amounts and compares expenditures from one location or geographic region to another. This adjusted cost of living data obtained from CPI helps employers increase the salaries paid to workers.
In a nutshell, Consumer Price Index is a term used to measure inflation in an economy. Since CPI determines the value of money, it sets a particular base for every transaction. Knowing how CPI is used may help consumers and businesses to foresee an inflationary situation and make well-versed economic decisions.
