Meaning

Gross Domestic Product (GDP) is the market value of all final goods and services produced inside a country's borders in one year. Final goods are goods bought by the last user, not used up again to make something else. GDP includes output by both Indians and foreigners working in India.

• Textbook (NCERT) formula: GDP ≡ Σ GVAᵢ. This means you add up the gross value added (GVA) of all producers in the country.
• Official formula used in India: GDP = GVA at basic prices + product taxes − product subsidies [2].

GDP measures the size of an economy. In the words of Class 10 NCERT, "GDP shows how big the economy is." Its growth rate is the headline number for how fast the economy is growing. Many policy ratios are measured against it, such as the fiscal deficit as a % of GDP.

Explanation

How GDP is measured: the value-added (product) method

• Value added = value of output − value of intermediate goods used. Intermediate goods are inputs that a firm buys and uses up, like wheat bought by a baker.
• If we add the full output of every firm, the same input gets counted again and again. This error is called double counting.
• Worked example (Class 12 NCERT): farmer and baker

	Farmer	Baker
Total production	100	200
Intermediate goods	0	50
Value added	100	150

• Correct GDP = 100 + 150 = ₹250.

• It is not 100 + 200 = ₹300, because the ₹50 of wheat is already inside the price of the bread.

• Firm-level identity: GVAᵢ ≡ Qᵢ − Zᵢ ≡ Vᵢ + Aᵢ − Zᵢ.

• Qᵢ = value of output
• Vᵢ = sales, including exports
• Aᵢ = change in inventories

• Zᵢ = intermediate goods used

• Worked example (firm):

• Sales ₹900, inventory rise ₹50, intermediate goods ₹400.
• GVA = 900 + 50 − 400 = ₹550.

What GDP counts and what it leaves out

• It counts production, not just sales.
• When goods are made but not sold, the firm's inventories rise. This rise is treated as investment, so the goods are still counted in this year's GDP.

• When goods from last year's stock are sold, inventories fall. This fall is subtracted, so those goods are not counted a second time.

• It counts only economic activities. These are activities done for money or money's worth, including payment in kind (being paid in goods instead of cash).

• It leaves out non-economic activities. These are things done out of love, care, sevā or duty, such as parents cooking at home, langar, or volunteering.
• Trap: a paid domestic cook is counted in GDP. The same cooking done by an unpaid family member is not [2].
• It leaves out transfers of existing assets. Buying shares or second-hand goods only changes who owns something that already exists. No new output is created.

Gross vs net, and the three ways to measure GDP

• "Gross" means depreciation is still included. Depreciation, also called consumption of fixed capital, is the wear and tear of machines and buildings during the year.
• Net Domestic Product (NDP) = GDP − depreciation.
• Three methods, one answer. GDP can be measured in three ways, and in theory all three give the same total:
• Product method: add up value added.
• Income method: add up wages + rent + interest + profit.

• Expenditure method: add up spending, C + I + G + (X − M). This is consumption + investment + government spending + exports − imports.

• Why the methods can differ in practice: real data never match perfectly. The gap between production-side GDP and expenditure-side GDP is called the statistical discrepancy [2].

What makes GDP rise or fall

• Nominal GDP is measured at current prices. It rises with both more output and higher prices.
• Real GDP is measured at constant (base-year) prices. It rises only when the actual quantity of output rises.
• GDP also moves with demand, shown by unplanned inventory change:
• Unplanned build-up of stocks → demand is lower than output → firms cut production next year → GDP and incomes fall.

• Unplanned run-down of stocks → demand is higher than output → firms raise production → GDP rises.

• Official GDP vs GVA: in the official formula, GDP moves with net product taxes as well as with GVA.

• A cut in taxes such as GST, or a rise in subsidies, makes GDP grow more slowly than GVA.

In India

• Who measures it: the Ministry of Statistics and Programme Implementation (MoSPI), through the National Statistics Office (NSO) [3][4].
• Official method:
• Output of each sector is shown as GVA at basic prices, which is GVA before product taxes are added and product subsidies are taken out.

• Adding net product taxes to this GVA gives GDP [2].

• GVA-to-GDP example, 2022-23 (current prices):

• GVA at basic prices ₹237.64 lakh crore + net product taxes ₹23.54 lakh crore = GDP ₹261.18 lakh crore [4].

• Depreciation for the whole economy, 2022-23:

• GDP was ₹2,61,17,627 crore and NDP was ₹2,24,35,361 crore.

• So depreciation was about ₹36.8 lakh crore, roughly 14% of GDP [4].

• Base-year history:

• On 30 January 2015, the base year moved from 2004-05 to 2011-12. From then on, headline figures stopped using "GDP at factor cost" [5].
• On 27 February 2026, a new series with base year 2022-23 replaced the 2011-12 series [2][6].
• 2022-23 was chosen because it was a "normal" year. The years 2017-18 to 2021-22 were ruled out because of the GST rollout and COVID-19. The choice was recommended by ACNAS (Advisory Committee on National Accounts Statistics), set up in 2024 [2].

• MoSPI aims to revise the base every five years [2].

• Standards followed:

• India uses SNA 2008 (the UN's System of National Accounts) and plans to move to SNA 2025 at the next base revision [2].

• India subscribes to the IMF's SDDS (Special Data Dissemination Standard) [2].

• Main changes in the new series:

• Double deflation (removing price changes from output and from inputs separately) is used for manufacturing and agriculture [2].
• Supply and Use Tables, a large cross-check of production against use, brought the statistical discrepancy to 0 in 2022-23 [4].
• The informal sector is now measured directly every year through the ASUSE and PLFS surveys [2].

• GST data is used for quarterly estimates and cross-checks [2].

• Latest figures:

• FY 2025-26 (Provisional Estimates, 5 June 2026):
  • Real GDP was ₹323.12 lakh crore, growth 7.7%. Nominal GDP was ₹346.36 lakh crore, growth 8.9% [4].
  • The Second Advance Estimate had put growth at 7.6% [6].
• Q1 (April–June) 2026-27:
  • Real GDP was ₹81.36 lakh crore, growth 7.8%.
  • Real GVA grew 8.2% [3].
• Largest sector shares in nominal GVA, 2025-26 [4]:
  • Financial, real estate, IT, professional services and ownership of dwellings: 27%
  • Agriculture, livestock, forestry and fishing: 18%
  • Manufacturing: 15%
• Investment inside GDP, 2022-23:
  • GFCF (Gross Fixed Capital Formation) was 32.4% of GDP.
  • Changes in Stocks was 0.7% and Valuables was 1.4% [4].

Don't confuse with

• GVA at basic prices: this measures output by sector. It does not include net product taxes. GDP = GVA + product taxes − product subsidies [2].
• GNP / GNI (Gross National Product / Income): GDP is domestic. It counts output inside India's borders, whoever produces it. GNP is national. It counts income earned by Indian residents anywhere, so GNP = GDP + net factor income from abroad.
• NDP (Net Domestic Product): this is GDP minus depreciation. GDP is "gross" because depreciation has not been taken out.
• Nominal vs real GDP: nominal GDP uses current prices and real GDP uses base-year prices. For 2025-26, nominal growth was 8.9% and real growth was 7.7% [4].

Prelims Hooks

• GDP counts final goods only. Adding the value of intermediate goods too causes double counting. By the product method, GDP = Σ value added.
• Official identity: GDP = GVA at basic prices + product taxes − product subsidies [2].
• Current base year = 2022-23, released on 27 February 2026 by MoSPI/NSO. It replaced 2011-12, which had been introduced on 30 January 2015 [2][5].
• Unsold output is still counted in GDP, as change in inventories (investment). Buying shares or second-hand goods is not counted.
• Trap: a paid domestic worker's work is counted in GDP. The same work done unpaid by a family member is not [2].
• "Domestic" means inside the borders: a foreign firm's output in India is counted in India's GDP. "National" (GNP) means owned by residents.

Mains Points

• GDP vs welfare:
• GDP leaves out unpaid care work, sevā and volunteering, so it undercounts women's contribution and people's well-being.
• It also says nothing about how income is shared, or about damage to the environment.

• Use this in GS-III answers on growth vs development, and in GS-I answers on the gender care gap.

• Better data, better policy:

• The 2022-23 series answers old criticism of the 2011-12 series. The main changes are double deflation, Supply and Use Tables (discrepancy 0 in 2022-23), and yearly ASUSE/PLFS surveys for the informal sector [2][4].

• More reliable GDP helps RBI's monetary policy, fiscal deficit targets set as % of GDP, and Finance Commission transfers.

• Reading the GDP–GVA gap:

• In Q1 2026-27, GDP grew 7.8% while GVA grew 8.2% [3]. This means net product taxes grew more slowly, for example because of GST rate cuts or higher subsidies.
• GVA gives the cleaner picture of production by sector. GDP gives the market-price figure used to compare countries.
