PURCHASING POWER OF PESO

The Purchasing Power of Peso (PPP) in Marinduque decreased to PhP 0.75 in June 2025. The PPP was registered at PhP 0.77 in June 2024. As a result, the amount of goods that can be presently purchased by consumers were fewer compared to when the PPP was higher.

TECHNICAL NOTES

•  Consumer Price Index is an indicator of the change in the average prices of a fixed basket
  of goods and services commonly purchased by households relative to a base year.
• Market Basket is a sample of goods and services, which is meant to represent the totality
  of all the goods and services purchased by households relative to a base year.
  •  To determine the commodities that will form the market basket for the 2018-based
    CPI, the Survey of Key Informants (SKI) was conducted in March 2021. The
    survey, which was conducted nationwide to store managers, sellers or proprietors,
    obtained information on the most commonly purchased goods and availed services
    by the households.
  • The commodities in the 2018-based CPI market basket are grouped/classified
    according to the 2020 Philippine Classification of Individual Consumption
    According to Purpose (PCOICOP) which is based on the United Nations COICOP.
    Meanwhile, the commodities in the 2012-based CPI market basket used the 2009
    PCOICOP version of classification of commodities.
  • Base year is a reference period, usually a year, at which the index number is set to 100.
    It is the reference point of the index number series. The CPI is rebased from base year
    2012 to base year 2018.
  •  Inflation Rate is the annual rate of change or the year-on-year change in the Consumer
    Price Index (CPI).
  • Purchasing Power of Peso 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 

Inflation Rate (reference month, reference year)
= [(CPI (reference month, reference year) - CPI (reference month, previous year)) / CPI (reference month, previous year)] x 100%
For example,
INFLATION RATE (June 2025) = [(CPI (June 2025) - CPI(June 2024)) / CPI(June 2024)] x 100%
= [(133.0 – 129.9) / 129.] x 100%
= (3.1 / 129.9) x 100%
≈ 2.4%
