In India, inflation is primarily measured by two main indices — WPI (Wholesale Price Index) and CPI (Consumer Price Index), which measure wholesale and retail-level price changes, respectively. The CPI calculates the difference in the price of commodities and services such as food, medical care, education, electronics etc, which Indian consumers buy for use.
On the other hand, the goods or services sold by businesses to smaller businesses for selling further is captured by the WPI. In India, both WPI (Wholesale Price Index) and CPI (Consumer Price Index) are used to measure inflation.
