Consumer Price Index (CPI)
Compilation and Base Year
The Consumer Price Index measures changes in the price level of a weighted average basket of consumer goods and services purchased by households. In India, CPI is compiled and released by MoSPI (Ministry of Statistics and Programme Implementation), which releases data monthly with a one-month lag. Since January 2026, the CPI series has been revised to a new base year of 2024 (Base Year 2024 = 100), replacing the earlier 2012 base year series. Under the new 2024-base series, the weight of food and beverages has been revised to 36.75% (down from 45.86% under the 2012-base series), and the weight of housing has been revised upward to 17.66% (up from 10.07%). The revised weights are derived from the Household Consumption Expenditure Survey (HCES) of 2023–24.
