Philippine Inflation Rate (1957-2014)

1. Price Increase Per Administration - How much has the prices of goods change within a specific administration. We use a  base price of Php 100 at the beginning of each administration. We then compute how much the prices of  goods has increased at the end of each administration.
2.Purchasing Power - This determines how much the purchasing power of money has reduced each administration. If the purchasing power of money has  reduced to 50% after 10 years, then Php 100 worth of goods purchased 10 years earlier can only purchase Php 50 worth of goods today.
