The Retail Price Index (RPI) measures the monthly change in the cost of a representative basket of retail goods and services in the United Kingdom. Unlike the Consumer Price Index, the RPI includes housing costs such as mortgage interest payments and council tax, making it a broader measure of inflation for households. It is a legacy measure but remains highly significant as it is used to calculate interest payments on index-linked gilts and for various wage negotiations.
The index is calculated by collecting prices for approximately 700 goods and services from various retail outlets. These prices are weighted based on household spending patterns to reflect their relative importance in the average budget.
