The Philippine Statistics Authority generates and announces the monthly Consumer Price Index (CPI) based on a nationwide survey of prices for a given basket of goods and services. Two important indicators, the inflation rate and purchasing power of the peso (PPP), are derived from the CPI which are important in monitoring price stability and the value of the country’s currency. 

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.

Retail Price is the price at which a commodity is sold for spot in small quantities for consumption.

Base Period/Base Year is the period, usually a year, at which the index number is set to 100. It is the reference point of the index number series.

Market Basket is a term used to refer to a sample of goods and services that are commonly purchased and bought by an average Filipino household.

Weight is a value attached to a commodity or ground of commodities to indicate the relative importance of that commodity or group of commodities in the market basket.

Inflation Rate is equivalent to a decline in the purchasing power of the peso. It is the change in the CPI over a specific period of time (usually a month or a year). That is, 


CPI1 - is the CPI in the previous period

CPI2 - is the CPI in the current period

The Purchasing Power of the Peso (PPP) is a measure of the real value of the peso in a given period relative to a chosen reference period. It is computed by getting the reciprocal of the CPI and multiplying the result by 100. That is,

Headline Inflation is the rate of change in the weighted average prices of all goods and services in the CPI basket.
