The Bureau of Labor Statistics calculates both the CPI and the PPI.
It is a branch of the US Department and serves as a crucial agency for the US Federal Statistical System. It also serves as the main agency for fact-finding for the US government in the broad subject of labor economics and statistics. The CPI, or consumer price index, is a measurement and tracking tool for changes in consumer prices over time. The Producer Price Index (PPI) is a collection of indices that tracks the normal change in selling prices that domestic producers of goods and services receive over time. PPIs, which track price changes, are computed from the seller's point of view. The Consumer Price Index (CPI), which gauges average price changes, is derived from a market basket of goods and services. PPIs monitor price variation from the standpoint of the seller.
