CPI = (updated cost / base period cost) X 100
Inflation Rate = ((New CPI - Old CPI)/Old CPI)) X 100
If the base period market basket is $200 and the 2014 market basket is $330, what is my CPI. If 2013 CPI was 162, what is my inflation rate for 2014?
CPI = ($330/$200) X 100 = 165
Inflation Rate = (165-162)/162) X 100 = 1.85% inflation rate
