Gross Domestic Product (GDP) is the total value of all final goods and services produced within a country over a period, usually a quarter or a year. It is the most widely used measure of the size and health of an economy.
What GDP is
GDP counts what an economy produces: cars, crops, software, haircuts, hospital care and much more, valued at market prices. Only final goods and services are counted, to avoid double counting: the steel in a car is counted once, as part of the car's value. When people say an economy is "growing", they usually mean GDP is rising.
How GDP is measured
GDP can be measured in three ways that should give the same result. The production approach adds up the value added by every sector. The expenditure approach adds consumption, investment, government spending and net exports (exports minus imports). The income approach adds wages, profits, rents and interest earned in the economy.
Nominal GDP uses current prices. Real GDP removes the effect of inflation, so it shows the true change in output. Growth rates reported in the news are usually real GDP growth.
How it works in India
India's GDP data is compiled by the National Statistics Office (NSO) under the Ministry of Statistics and Programme Implementation. Quarterly estimates are released about two months after each quarter ends, and annual estimates are revised as more data arrives. India's economy is driven by services, industry and agriculture, with private consumption forming a large share of spending.
A simple example
If India's real GDP in one year is ₹100 lakh crore and the next year ₹107 lakh crore, real GDP growth is 7%. If prices also rose 5%, nominal GDP growth would be roughly 12%. Dividing GDP by population gives GDP per capita, a rough measure of average income.
Why it matters for investors
GDP growth affects company revenues and profits, employment, government finances and interest rate decisions. Strong growth often supports corporate earnings and markets over time, while slowing growth can weigh on them. Investors also watch which sectors drive growth.
GDP and the stock market
The link between GDP and share prices is real but loose. Markets look ahead and often move before GDP data confirms a trend. Listed companies are only part of the economy, and some sectors, such as IT services, earn much of their revenue abroad. Over long periods, however, economies that grow strongly tend to support rising corporate profits.
Other indicators to watch alongside GDP
Because GDP data arrives with a delay, analysts also follow faster indicators: the Index of Industrial Production for factory output, Purchasing Managers' Indices (PMI) for business activity, GST collections, credit growth, auto sales and power demand. Together, these give an earlier picture of how the economy is moving before official GDP figures confirm it.
Common misconceptions
"High GDP means everyone is richer." GDP does not show how income is distributed.
"GDP growth means stocks will rise." Markets often anticipate data and react to many other factors.
"Nominal and real growth are the same." Real growth removes inflation.

Summary
GDP is the total value of final goods and services produced in a country. It can be measured by production, expenditure or income; real GDP removes inflation. India's NSO publishes quarterly data. GDP growth influences profits, jobs and interest rates, but markets often move ahead of the data, and GDP says nothing about income distribution.
