Concepts and Definitions

Consumer Price Index (CPI)

        The CPI is an indicator of the changes in the average retail prices of a fixed basket of goods and services commonly purchased by households relative to a base year.

Uses of CPI

         The CPI is most widely used in the calculation of the inflation rate and purchasing power of peso. It is a major statistical series used for economic analysis and as a monitoring indicator of government economic policy.

Computation of CPI

                The computation of the CPI involves consideration of the following important points:

       a. Base Period- The reference date or base period is the benchmark orreference date or period at

            which the  index is taken as equal to 100.

       b. Market Basket- A sample of the thousands of varieties of goods purchased for consumption and

          services availed by the households in the country selected to represent the composite price behavior of all      

          goods and services purchased by consumers.

       c. Weighting System- The weighting pattern uses the expenditures on various consumers’ items purchased

           by households as a proportion to total expenditure.

       d. Formula-The formula used in computing the CPI is the weighted arithmeticmean of price relatives, the

           Laspeyre’s formula with a fixed based year period (2006) weights.


         Inflation Rate is the rate of change of the CPI expressed in percent. Inflationis interpreted in terms of

         declining purchasing power of peso.


         Headline Inflation refers to the rate of change in the CPI, a measure of theaverage standard “basket” of goods

         and services consumed by a typical family.


              Purchasing Power of Peso shows how much the peso in the base period is worth in the current period.

         It is computed as the reciprocal of the CPI for the period under review multiplied by 100.
