Technical Notes

Consumer Price Index (CPI) A single number used to measure changes in the average retail prices of a market basket or collection of goods and services commonly purchased by an average Filipino household. It shows how much on the average, prices of goods and services have increased or decreased from a particular reference period known as base year.

The CPI measures the changes in the price level of goods and services that most people buy for their day-to-day consumption relative to a base year (currently at year 2018)

The Purchasing Power of Peso (PPP) gives an indication of the real value of the peso (how much it is worth) in a given period relative to its value in a base period. Or it measures how much the peso in the reference year is worth in another year.

Inflation Rate (IR) is the rate of change in the average price level between two periods (year-on year/month-on-month as measured by the CPI). 

Base Year (BY) is the reference point of the index number series, at which the index number is set to zero.

Market Basket (MB) is a sample of goods and services used to represent all goods and services produced or bought.

The monthly Consumers Price Index is computed based on the average retail prices of goods and services collected during the first week and mid-month of the reference month. 

Retail Price - the actual price at which retailers sell a commodity on spot or earliest delivery, usually in small quantities for consumption and not for resale. It is confined to transactions on cash basis in the free market and excludes black-market prices and prices of commodities that are on sale as in summer sales, anniversary sales, Christmas sales, etc.
