It is most widely used in the calculation of the inflation rate and purchasing power of the peso (PPP). 

Relative to this, daily, weekly, and bi-monthly price surveys are conducted nationwide at the provincial offices including the District Offices of the National Capital Region (NCR) to be able to generate monthly CPI for All Income Households and CPI for the Bottom 30% Income Households. Indicators produced from price surveys are regarded as designated statistics.
