PRICE STATISTICS
• PRICE STATISTICS INCLUDES
COLLECTION OF RETAIL AND WHOLE
SALE PRICES AND COMPUTATION OF
FOLLOWING INDICES:-

• 1. CONSUMER PRICE INDEX (C.P.I)
• 2. WHOLESALE PRICE INDEX (W.P.I)
• 3. SENSITIVE PRICE INDICATOR (S.P.I)

Consumer Price Index
• “ Consumer Price Index is the main
measure of price changes at the retail level.
It measures changes in the cost of buying a
representative fixed basket of goods and
services and is generally accepted as a
measure of inflation in the country”.

SENSITIVE PRICE
INDICATOR (SPI)

• Sensitive Price Indicator (SPI) is
designed to assess price movement of
essential consumer items at short
intervals (on weekly basis ).

WHOLE SALE PRICE INDEX (WPI)

Wholesale price index ( WPI) is designed to
measure the change of price in the primary
and wholesale markets.

Why Three Types of Indices?
• CPI measures Inflation rate in the country
• SPI is computed to assess the price
movement of essential commodities at short
interval of time to review the price situation
in the country.
• WPI measures the General Price level in
the whole sale market.

WHAT CPI MEASURES?
• It measures Price changes of fixed market
basket of goods and services of constant
quality and quantity.
• It tells how much cost of living has risen or
fallen due to price changes irrespective of
changes in consumer behaviour or quality
of goods.
• It does not reflect the cost of living or in
house hold consumption expenditure as
such but only the influence of price
fluctuation on the trend.

Selection of Markets/Outlets
and Cities
• Items are selected on the basis of Family Budget
Survey
• Markets are selected through retail and wholesale
trade survey.
• Outlets are selected on transaction value basis.
• Cities are selected on population basis
• Stratified sampling are used for selection of
cities.

Weights for CPI
The results of Family Budget Survey provide the average
percentage expenditure(Consumption pattern) of Households on
each item/each commodity group and for each income group for
the cities covered in CPI. These average percentage expenditures
on item and commodity groups are called weights and are being
used in computation of the CPI.
Po x qo
Wi = ------------- x 100
∑ Po x qo

Example: 1. Total Expenditure: Rs. 3000,
2. Expenditure on Wheat Flour:- Rs. 100
3. % of Expenditure on Wheat flour = (100/3000)*100 = 3.33
Weight of Wheat flour = 3.33%

FORMULA USED FOR COMPUTATION OF CPI

Laspeyre's formula as given below is being used for
the computation of CPI.
∑ (Pn/Po) x wi
In = --------------------- x 100
∑ wi
Where In = CPI for the nth period
Pn = price of an item in the in the nth period
Po = price of an item in the base period
wi = weight of the ith item in the base period =
Po x qo / ∑ Po x Qo
∑ wi = Total weight of all items.

WEIGHTS FOR WPI
• The value of marketable surplus is being used for
deriving weights of commodities/items included in
WPI. The value of marketable surplus is the value
of commodity available for sale in wholesale
market. It is equal to the total value of production
less consumption by the producers less exports (if
any) plus imports.
• Example:- Production – Self Consumption +Imports- Exports
Wheat = (100 )-(20) + (10) – (10) =80
Value of Marketing Surplus= 80 x 1000 = 80000
Total Value of all the Items included in WPI =100,0000
% of Wheat in Total Value = (80000/1000000) x 100 = 8%
