Consumer Price Index (CPI)

The CPI is an indicator of the change 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 monitoring indicator of the government economic policy.
• Measures the composite change in the consumer prices in various commodities overtime.

Computation of CPI

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

1. Base Period – The reference date or base period is the benchmark or reference date or period at which the index is taken as equal to 100.
2. Market Basket – A sample of the thousands of varieties of goods purchased for consumption and the services availed by the households in the country selected to represent the composite price behavior of all goods and services purchased by consumers.
3. Weighting System - The weighting pattern uses the expenditures on various consumer items purchased by households as a proportion to total expenditure.
4. Formula - The formula used in computing the CPI is the weighted arithmetic mean of price relatives, the Laspeyre’s formula with a fixed base year period (2018) weights.
5. Geographic Coverage – CPI values are computed at the national, regional, and provincial levels, and or selected cities.

Inflation Rate

The inflation rate is the annual rate of change, or the year-on-year change of CPI expressed in percent. Inflation is interpreted in terms of declining purchasing power of money.
