GDP stands for Gross Domestic Product. It is often quoted in newspapers, TV news, and government, central bank, and business reports. It is widely used as a reference point for the health of the domestic and global, Indian economy [3]. In this research paper we collected a secondary data from Indian budget website (1950–1951 to 2021–2022). The factors [4] involved in the GDP [1] are PFCE (Personal Consumption Expenditure), GFCE (Government Final Consumption Expenditure), GFCF (gross fixed capital formation), CIS (change in stock), exports of goods and services, imports of goods and services, Discrepancies. We apply Simple regression to analyze GDP on PFCE, GFCE, GFCF, CIS, exports of goods and services, imports of goods and services, Discrepancies we compute that PFCE, GFCE, GFCF, imports of goods and services and exports of goods and services are highly significant and CIS is moderately significant but there is low significant effect of Discrepancies, we also used Multiple regression on PFCE, GFCE, GFCF, CIS, exports of goods and services, imports of goods and services, Discrepancies are effecting significantly.
