What is Retail Prices Index?

  • The Retail Prices Index (RPI) is a measure of inflation published monthly by the Office for National Statistics.
  • RPI tracks changes in the cost of a fixed basket of goods and services.
  • It is produced by combining around 180,000 price quotes for over 650 items.

Pensioners were given some welcome news after the UK's top statistician said RPI, a key measure of inflation linked to retirement income and a raft of other investments and services, should remain unchanged.
