Producer and Retail Price Indices

Published 18 July 19

The Producer Price Index (PPI) measures changes in the prices of goods sold by UK based manufacturers in the form of an index. It is therefore useful as an indicator of movements in factory-gate* prices of manufactured products.

A PPI is available for manufactured liquid milk and cheese and curd.

The Retail Price Index (RPI) measures changes in the prices of goods sold by retailers (or prices paid by consumers). RPIs for fresh milk and cheese are reported here.

Using the PPI together with the Retail Price Indices (RPI) provides some insight into the relative rate of change in prices of goods sold at different parts of the supply chain.

*The ONS definition of the ‘factory-gate’ price is “the price of goods sold by UK manufacturers and is the actual cost of manufacturing goods before any additional charges are added, which would give a profit. It includes costs such as labour, raw materials and energy, as well as interest on loans, site or building maintenance, or rent.” The ‘factory-gate price is a measure of the price of goods before they reach the distribution or retail sector.

The PPIs are calculated using data supplied from individual UK manufacturers, importers and exporters. A full explanation of how the PPI is calculated can be obtained from the ONS through this link.
