What is Gross Domestic Product (GDP)?

Gross Domestic Product (GDP) is the total monetary value of all final goods and services produced within a country's borders during a specific period, typically a financial year or quarter. It is the most widely used indicator of a nation's economic health and size. GDP can be measured in three ways: the production (output) method, the income method, and the expenditure method -- all three yield the same result theoretically.

In India, GDP estimates are prepared by the Ministry of Statistics and Programme Implementation (MoSPI) under the National Statistical Office (NSO). The current base year for GDP calculation is 2022-23 (revised from 2011-12 in February 2026). India uses GDP at constant prices (real GDP) to measure growth by removing the effect of inflation, while GDP at current prices (nominal GDP) reflects the value at prevailing market prices.

India is the 5th largest economy in the world by nominal GDP (approximately $3.8 trillion in FY2025-26) and the 3rd largest by Purchasing Power Parity (PPP) at around $17.7 trillion (IMF, 2025), behind only the United States and China.

UPSC Exam Corner

Prelims: Key Facts

  • GDP is measured by NSO under MoSPI; new base year is 2022-23
  • GDP at factor cost was replaced by GDP at market prices and GVA at basic prices from the 2011-12 series onward
  • India is the 3rd largest economy by PPP and 5th largest by nominal GDP
  • Advance Estimate of GDP is released in January each year
  • GDP = C + I + G + (X - M) under the expenditure method
