Comparing UK Inflation Measures
Compare the main UK annual inflation measures. All three show the percentage change in prices over 12 months.
CPI is the main measure used for the Bank of England's 2% inflation target and international comparisons. It tracks the cost of a representative basket of goods and services purchased by UK households.
CPIH includes owner occupiers' housing costs and is ONS's lead consumer price inflation measure. It provides a more comprehensive view of household costs by including the costs associated with owning a home.
RPI is an older legacy measure. It is still published and used in some contracts (including some index-linked gilts and rail fare increases), but it is not an Accredited Official Statistic and should be treated carefully.
The inflation rate shows how quickly prices are rising compared with a year earlier (expressed as a percentage). A price index shows the cumulative price level relative to a base year (e.g. 2015=100).
