National Income Accounting: GDP, GNP, NNP, GVA, Base Year 2022-23 & the New GDP Series (UPSC Economy)
What GDP Counts and the Three Methods
🎯 Exam priority: Important. About eight direct questions in ten years — real sector, capital formation, GNP, intangible investment, PPP — plus constant use of GDP numbers inside current-affairs questions. The 2026 rebasing of GDP is brand new and exactly the kind of thing UPSC asks within a year.
"The economy grew 7.6 per cent." Behind that headline sits a precise accounting system — what counts, at which prices, measured in which year. This note gives you that system, from the circular flow of income to the new 2022-23 base year.
What is counted: final output, value added, flows
GDP (Gross Domestic Product) is the market value of all final goods and services produced within the geographical boundary of a country in a year. "Final" matters: counting intermediate goods (wheat sold to a flour mill) and the final product (bread) would be double counting.
Value added = value of output − value of intermediate consumption. Gross Value Added (GVA) is the sum of value added in all sectors before deducting depreciation; adding the right taxes gives GDP.
Worked example of value added. A farmer grows wheat and sells it to a miller for ₹100; the miller sells flour to a baker for ₹150; the baker sells bread to households for ₹200. Value added is ₹100 (farmer) + ₹50 (miller) + ₹50 (baker) = ₹200 — exactly the price of the final good. Adding the sales (100 + 150 + 200 = ₹450) would triple-count the wheat.
Circular flow. Households supply factors of production (land, labour, capital, entrepreneurship) to firms and receive factor incomes; they spend those incomes on firms' output. Leakages out of the loop (saving, taxes, imports) are matched by injections (investment, government spending, exports) — which is why the production, income and expenditure totals coincide.
Stock vs flow. GDP is a flow (per year); wealth, capital stock, foreign-exchange reserves and the public debt are stocks (at a point in time). Questions often hide this distinction.
What is excluded: purely financial transactions (buying shares, transferring money), second-hand goods (their original sale was counted already), and — in practice — unpaid household work and the unrecorded economy.
Three ways of measuring — one answer
Method | What it adds up | Formula / idea |
Product (value-added) method | Value added by each sector — primary, secondary, tertiary | Σ(GVA) + net product taxes = GDP |
Expenditure method | All spending on final goods and services | GDP = C + I + G + (X − M): private consumption + investment (capital formation) + government spending + net exports |
Income method | Incomes earned by factors of production | Wages + rent + interest + profit (operating surplus) + mixed income of the self-employed |
In theory the three give the same figure — what is produced is either spent or earned. In practice there is a statistical discrepancy between the production and expenditure sides, which the new GDP series (below) tries to shrink by integrating Supply and Use Tables.
The real sector means the part of the economy that actually produces goods and services — farming, manufacturing, trade, transport and so on — as opposed to the financial sector (banks, markets, insurance), a distinction UPSC used in 2022.
From GDP to Personal Disposable Income; Factor Cost, Basic and Market Prices
"GDP", "GNP", "NNP" and "National Income" are different cuts through the same circular flow. Know the staircase and the one-word difference at each step.
The staircase: GDP → GNP → NNP → NI → PI → PDI
Step | Measure | How you get it |
1 | GDP (at market prices) | Final output within the country's borders |
2 | GNP | GDP + Net Factor Income from Abroad (NFIA) = what citizens earn, wherever they work |
3 | NNP (at market prices) | GNP − depreciation (consumption of fixed capital) |
4 | National Income (NNP at factor cost) | NNP at market prices − net indirect taxes (indirect taxes − subsidies) |
5 | Personal Income | NI − undistributed profits − corporate tax − net interest paid by households + transfer payments to households |
6 | Personal Disposable Income | PI − personal tax and non-tax payments — the part households can consume or save |
NFIA = factor income earned by Indians abroad − factor income earned by foreigners in India. India's NFIA is typically negative (more income flows out as interest, profits and dividends than comes in), so GNP is a little lower than GDP. A Hyundai plant in India adds to India's GDP but not to India's GNP.
Remittances are not counted in factor income; they are transfers (see the Balance of Payments article).
Per capita income = national income ÷ population. UPSC's 2018 warning: a rise in absolute and per-capita real GNP does not connote a higher level of economic development if poverty and unemployment increase — growth in the headline does not guarantee welfare.
Factor cost, basic prices and market prices
Factor cost counts only payments to factors of production (wages, rent, interest, profit) — no taxes at all.
Basic prices add production taxes (net of production subsidies) — taxes tied to the act of production, independent of the volume produced, such as land revenue, stamp duty and registration fees.
Market prices add further product taxes (net of product subsidies) — taxes levied per unit of product, such as GST/excise and customs duties.
Chain: GVA at factor cost + net production taxes = GVA at basic prices; GVA at basic prices + net product taxes = GDP at market prices.
January 2015 change: with the 2011-12 base year, the statistics office dropped "GDP at factor cost" as the headline and began reporting GVA at basic prices (to measure the supply side) and GDP at market prices (now simply "GDP"). That is why the Economic Survey quotes both a GDP growth and a (slightly different) GVA growth: for 2025-26 the First Advance Estimates were 7.4% real GDP growth and 7.3% GVA growth.
Nominal vs Real, the Deflator, PPP and the 2026 Rebasing
A rupee-value comparison across years is meaningless without stripping out price changes — hence the nominal/real distinction and the deflator.
Nominal vs real, GDP deflator, PPP
Nominal (current-price) GDP values output at the prices of the same year; real (constant-price) GDP values it at the prices of a fixed base year. Growth in real GDP measures growth in the volume of output; growth in nominal GDP also contains inflation.
GDP deflator = (nominal GDP ÷ real GDP) × 100. It is an economy-wide price index — wider than the CPI because it covers every domestically produced good and service (including capital goods and exports) and excludes imports, and its weights change every year with the output mix.
Purchasing Power Parity (PPP) exchange rates compare the price of the same basket of goods across countries. Because non-traded services are cheaper in poorer countries, GDP at PPP is larger than at market exchange rates for India — the reason India is ranked higher on PPP than on nominal GDP.
India's financial year is April–March; GDP is estimated by the National Statistics Office (NSO) in MoSPI, first as Advance Estimates (first in early January, second at the end of February), then Provisional Estimates (31 May) and later Revised Estimates.
The 2026 rebasing — base year 2022-23
On 27 February 2026 MoSPI released the new series of GDP with base year 2022-23, replacing the 2011-12 series (which itself had replaced the 2004-05 series in 2015). FY 2022-23 was picked as a recent "normal" year after COVID with robust data.
Why rebase? To capture structural change, use new data sources and improve methods. Base years are revised periodically; ordinary annual revisions change only numbers, not methods.
Key changes: (i) double deflation — inputs and outputs are deflated separately to get real value added — now used in agriculture and manufacturing (single extrapolation/volume extrapolation elsewhere); (ii) segregating activities of multi-activity enterprises in the private corporate sector; (iii) annual survey data for the unincorporated sector (informal economy); (iv) administrative data such as GST and the e-Vahan vehicle portal; (v) private consumption classified by COICOP 2018; (vi) Supply and Use Tables to reconcile production- and expenditure-side estimates.
Headline numbers (new series): real GDP growth 7.2% in 2023-24, 7.1% in 2024-25 and 7.6% (Second Advance Estimate) in 2025-26; nominal GDP growth 11.0%, 9.7% and 8.6% respectively. The 2025-26 figure is higher than the 7.4% First Advance Estimate (old base) quoted in the Economic Survey. Manufacturing emerged as a major driver of the three years.
A new CPI series (base 2024=100) was introduced at the same time — see the Inflation article.
GDP and Welfare; Capital Formation and Saving
Is higher GDP the same as higher well-being? NCERT's answer — and UPSC's — is "no, not necessarily".
Why GDP is not welfare
Distribution: if the rise in GDP is concentrated in a few hands, most people can be worse off. NCERT's example: 100 people earning ₹10 each (GDP ₹1,000) become 90 earning ₹9 and 10 earning ₹20 — GDP rises to ₹1,010 while 90% of people lose income.
Non-monetary transactions: household work done by women, barter and other unpaid activity are not counted, so GDP understates economic activity — especially in developing countries.
Externalities: pollution from a factory is a cost nobody is charged for, so GDP rises while welfare falls. Efforts such as Green GDP / environmental accounting try to correct for the depletion of natural capital; India has not adopted an official Green GDP.
Hence the use of broader indices alongside GDP — HDI, Multidimensional Poverty Index, Gross National Happiness (Bhutan) — covered in Article 24.
Capital, investment and saving
Capital formation (investment) is the addition to the stock of capital — machines, buildings, infrastructure, and also intangible assets. Gross Fixed Capital Formation (GFCF) is the main component; with changes in stocks (inventories) and valuables it makes up Gross Capital Formation. For 2025-26 the Economic Survey puts the GFCF share at 30.0% of GDP, while private consumption (PFCE) rose to 61.5% of GDP, the highest since FY12 — domestic demand is the anchor of growth.
Physical capital: fixed capital (tools, machinery, buildings that are used again and again — a farmer's plough, a tractor) vs working capital (raw materials and cash used up in production and repurchased each cycle — seeds, fertiliser, money in hand). UPSC set a pairs question on this in 2024.
Intangible investments — brand recognition, intellectual property, software, a proprietary mailing list of clients — are assets with no physical form that give returns over several years; inventory is a tangible asset. This was the 2023 question.
Saving → investment. Gross domestic saving (households, private corporates, public sector) funds investment; any shortfall is financed by foreign saving, i.e. a current-account deficit. A high saving rate does not guarantee output growth if the capital–output ratio is high (each extra unit of output needs a lot of capital) — UPSC's 2018 answer on why capital formation may not raise output in a high-saving economy.
Why this matters for UPSC
Expect a question that tests one precise difference: GDP vs GNP, factor cost vs basic vs market prices, production tax vs product tax, nominal vs real, GVA vs GDP. Memorise the staircase and the chain.
Currency: base year 2022-23, the 27 Feb 2026 date, double deflation, and the 7.6% / 7.1% / 7.2% growth path are the new facts — and the 2025-26 First Advance Estimate (7.4%) in the Survey was on the old base.

Test Yourself: Practice Questions & PYQs
Nine practice questions on the staircase of aggregates, price concepts and the new GDP series, followed by real UPSC questions on this topic.
Practice Questions
Q1. Consider the following statements:
1. Gross National Product equals Gross Domestic Product plus net factor income from abroad.
2. Net National Product at market prices equals GNP minus depreciation.
3. National Income (NNP at factor cost) equals NNP at market prices plus net indirect taxes.
Which of the statements given above are correct?
(a) 2 and 3 only
(b) 1, 2 and 3
(c) 1 and 3 only
(d) 1 and 2 only
Show answer
Answer: (d) — 1 and 2 are correct. National Income is NNP at market prices MINUS net indirect taxes (indirect taxes less subsidies) — the taxes inflate market prices but never reach the factors of production — so 3 is wrong.
Q2. GVA at basic prices differs from GDP at market prices in that
(a) GDP at market prices includes net product taxes while GVA at basic prices does not
(b) GVA at basic prices includes imports
(c) GDP at market prices excludes government services
(d) GVA at basic prices includes depreciation while GDP excludes it
Show answer
Answer: (a) — GVA at basic prices + (product taxes − product subsidies) = GDP at market prices. Since January 2015 India reports both: GVA for the supply side, GDP for the headline.
Q3. An Indian software engineer working in the USA sends part of her salary home. Which of the following is correct?
(a) Her salary is included in neither India's GDP nor India's GNP
(b) Her salary is included in India's GNP but not in India's GDP
(c) Her salary is included in India's GDP but not in India's GNP
(d) Her entire salary is included in India's GDP
Show answer
Answer: (b) — GDP counts production inside India's borders; GNP counts incomes of India's residents wherever earned (via net factor income from abroad). The money she remits is a transfer in the balance of payments, not a separate item of production.
Q4. In national income accounting, 'production taxes' differ from 'product taxes' because production taxes are
(a) levied on production regardless of the volume of output (e.g., land revenue, stamp duty)
(b) levied per unit of output sold
(c) paid only on imported goods
(d) paid only by the government sector
Show answer
Answer: (a) — Production taxes (net of production subsidies) are added to factor cost to reach basic prices; product taxes (GST, excise, customs) are per unit and are added to basic prices to reach market prices.
Q5. Statement-I: Growth in nominal GDP can be higher than growth in real GDP in the same year.
Statement-II: Nominal GDP is measured at current prices and therefore also reflects inflation.
Which one of the following is correct in respect of the above statements?
(a) Both Statement-I and Statement-II are correct but Statement-II does not explain Statement-I
(b) Statement-I is not correct but Statement-II is correct
(c) Both Statement-I and Statement-II are correct and Statement-II explains Statement-I
(d) Statement-I is correct but Statement-II is not correct
Show answer
Answer: (c) — When prices rise, current-price GDP grows faster than constant-price GDP because it carries the inflation component as well as the volume growth. (In India's FY26 new series: real growth 7.6%, nominal 8.6%.)
Q6. The new series of GDP released by the Ministry of Statistics and Programme Implementation in February 2026 uses which base year?
(a) 2004-05
(b) 2011-12
(c) 2022-23
(d) 2024-25
Show answer
Answer: (c) — FY 2022-23 — a recent 'normal' post-COVID year — replaced 2011-12 as the base. (The CPI new series is separately based on 2024=100.)
Q7. Consider the following statements about the new GDP series (base 2022-23):
1. It uses double deflation in agriculture and manufacturing.
2. It integrates Supply and Use Tables to reduce the discrepancy between production-side and expenditure-side estimates.
3. It treats government subsidies as part of product taxes only.
Which of the statements given above are correct?
(a) 1, 2 and 3
(b) 2 and 3 only
(c) 1 only
(d) 1 and 2 only
Show answer
Answer: (d) — 1 and 2 are stated in MoSPI's press note. Statement 3 is invented — subsidies are netted from taxes in the ordinary way and nothing about them is special to the new series.
Q8. A GDP deflator differs from a Consumer Price Index mainly because the deflator
(a) is calculated only for agricultural goods
(b) includes imported goods but not exports
(c) covers all goods and services produced domestically and excludes imports, whereas the CPI tracks a fixed basket bought by consumers
(d) is published monthly while the CPI is annual
Show answer
Answer: (c) — GDP deflator = (nominal GDP ÷ real GDP) × 100 — an economy-wide price measure of domestic output; CPI follows the consumer basket (including imported consumer goods).
Q9. Which of the following is a reason why a rise in GDP does not always imply a rise in welfare?
1. The additional income may go to a small section of the population.
2. Unpaid household work is not counted in GDP.
3. Pollution costs are not deducted from GDP.
(a) 1 and 2 only
(b) 1, 2 and 3
(c) 2 and 3 only
(d) 1 only
Show answer
Answer: (b) — All three are NCERT's reasons — distribution, non-monetary activity and externalities.
UPSC Previous Year Questions (PYQs)
Real UPSC Prelims questions, checked against the official paper and answer key.
Q1. (2018) Increase in absolute and per capital real GNP do NOT connote a higher level of economic development, if
(a) imports grow faster than exports.
(b) industrial output fails to keep pace with agricultural output.
(c) poverty and unemployment increase.
(d) agricultural output fails to keep pace with industrial output.
Show answer
Answer: (c) — Rising GNP or per-capita income is only an average. If poverty and unemployment are rising, the growth has not translated into development — that is the point of the NCERT 'GDP and welfare' discussion.
Q2. (2018) Despite being a high saving economy, capital formation may not result in significant increase in output due to
(a) illiteracy
(b) high population density
(c) high capital-output ratio
(d) weak administrative machinery
Show answer
Answer: (c) — A high saving rate gives resources for investment, but output depends on how much output each unit of capital yields. A high capital–output ratio means each extra unit of output needs a lot of capital, so heavy capital formation may raise output only slightly.
Q3. (2022) Which of the following activities constitute real sector in the economy?
1. Farmers harvesting their crops
2. Textile mills converting raw cotton into fabrics
3. A commercial bank lending money to a trading company
4. A corporate body issuing Rupee Denominated Bonds overseas
Select the correct answer using the code given below:
(a) 1 and 2 only
(b) 1, 3 and 4 only
(c) 1, 2, 3 and 4
(d) 2, 3 and 4 only
Show answer
Answer: (a) — The real sector produces goods and services — harvesting crops (1) and turning cotton into fabric (2). Bank lending (3) and a company issuing rupee bonds abroad (4) are financial-sector activities.
Q4. (2023) Consider the investments in the following assets:
1. Brand recognition
2. Inventory
3. Intellectual property
4. Mailing list of clients
How many of the above are considered intangible investments?
(a) All four
(b) Only three
(c) Only one
(d) Only two
Show answer
Answer: (b) — Intangible investments have no physical form but yield returns over years: brand recognition (1), intellectual property (3) and a client mailing list (4). Inventory (2) is a tangible asset, so three of the four qualify.
Q5. (2024) With reference to physical capital in Indian economy, consider the following pairs: Items Category
1. Farmer's plough Working capital
2. Computer Fixed capital
3. Yarn used by the weaver Fixed capital
4. Petrol Working capital
How many of the above pairs are correctly matched?
(a) Only three
(b) Only two
(c) All four
(d) Only one
Show answer
Answer: (b) — Fixed capital (tools, machines, computers) is used repeatedly; working capital (raw material, fuel) is used up in each cycle. A computer — fixed ✔; petrol — working ✔. A plough is fixed capital (not working) and the weaver's yarn is working capital (not fixed). Two pairs are right.
Q6. (2024) With reference to the sectors of the Indian economy, consider the following pairs: Economic activity Sector
1. Storage of agricultural produce Secondary
2. Dairy farm Primary
3. Mineral exploration Tertiary
4. Weaving cloth Secondary
How many of the pairs given above are correctly matched?
(a) All four
(b) Only one
(c) Only two
(d) Only three
Show answer
Answer: (c) — Primary = extraction/farming (dairy farm ✔, and mineral exploration is primary, not tertiary); secondary = manufacturing (weaving cloth ✔); tertiary = services (storage of produce is a service, not secondary). Two pairs are correct.
