Retail Prices Index

(RPI).

Historically, RPI was the primary measure of consumer price inflation in the UK, calculated as the change from month to month in the prices of a standard basket of retail goods and services.

Different goods and services are included in the RPI compared with the UK Consumer Prices Index (CPI) and the method of calculation of the two indices is different.
