Retail Prices Index, UK

This shows the sectors and sub-sectors which make up the Retail Prices Index. Each index is normalized to a value of 100 as of January 1987. RPI is one of two major measures of headline inflation; the other is CPI, the Consumer Prices Index. RPI was first calculated in 1947, and although it has been replaced by CPI for government planning purposes, it's still used for calculating index-linking (for instance, for pensions). RPI is also often used as a place to start in salary negotiations. Find out more on the National Statistics website here.
