COMPONENTS OF CPI:

A. 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. Starting February 2022, the base period is 2018.

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 consumer items purchased by households as proportion to total expenditure.

D. 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.

E. Geographic Coverage      
CPI values are computed at the national, regional, and provincial levels, and for selected cities.

INFLATION RATE      
The inflation rate is the annual or monthly rate of change of the CPI expressed in percent. Inflation is interpreted in terms of declining purchasing power of money.

HEADLINE INFLATION RATE      
The headline inflation rate refers to the rate of change in the CPI, a measure of the average standard “basket” of goods and services consumed by a typical family.

YEAR-ON-YEAR INFLATION RATE      
Year-On-Year Inflation Rate is the annual percentage change of CPI. For example, the percentage change of CPI between August 2023 and August 2024.

MONTH-ON-MONTH INFLATION RATE      
Month-On-Month Inflation Rate is the monthly percentage change of CPI. For example, the percentage changes of CPI between August 2024 and July 2024.

PURCHASING POWER OF PESO (PPP)      
The purchasing power of peso (PPP) shows how much 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.

For example, the PhP 1.00 in 2018 is valued only at PhP 0.78 in 2023.
