About WPI vs PPI

The Wholesale Price Index (WPI) is a vital economic indicator that measures price changes at the producer or wholesale level, serving as a key tool for monitoring inflation on the production side of the economy. While it does not account for retail margins, WPI remains a widely used inflation measure in India and plays a crucial role in economic analysis and policy formulation.

On the other hand, the Producer Price Index (PPI) captures the average change in prices of goods and services as they leave the place of production or enter further production stages. PPI offers a more precise understanding of inflationary trends across various stages of the supply chain. It is conceptually aligned with the System of National Accounts (SNA) and is valuable as a deflator for estimating real values in national accounts.

The compilation of WPI and PPI is undertaken by DPIIT under the Ministry of Commerce and Industry, while the IIP is compiled by the Ministry of Statistics and Programme Implementation (MoSPI).
