Expenditure method
Topic: National Income Accounting: GDP, GVA and Welfare · NCERT: Class 12, Ch 2 "National Income Accounting"
Meaning
The expenditure method measures GDP (Gross Domestic Product: the value of all final goods and services produced inside a country in one year) by adding up all the money spent on final goods and services made inside the country:
GDP ≡ C + I + G + X − M
where C = consumption, I = investment, G = government spending, X = exports and M = imports.
It measures the economy from the demand side. It shows who buys the country's output: households, firms, the government or foreigners. So it tells us what is driving growth: consumption, investment or trade.
Explanation
How it works: count only final spending
- Final goods are goods bought for end use. They are not processed or resold in the same year.
- Intermediate goods are goods used up while making other goods. Example: wheat that a baker turns into bread.
- Only final spending is counted. The value of intermediate goods is already inside the price of the final good. Adding it again is double counting.
- Farmer–baker example:
- Consumers spend ₹200 on bread.
- Households also buy ₹50 of wheat directly for their own use. This is final use.
- Expenditure-method GDP = ₹200 + ₹50 = ₹250.
-
The wheat that bakers buy is intermediate, so it is not added again.
-
Cotton–cloth check (NCERT Tables 2.2–2.3):
- Firm A grows cotton worth ₹50. Firm B turns it into cloth and sells the cloth for ₹200.
- Final spending is only on the cloth, so GDP = ₹200.
- Adding total sales (50 + 200 = ₹250) is wrong, because the cotton gets counted twice.
- The value-added and income methods also give ₹200.
The components: C, I, G and X − M
| Symbol | Component | Simple meaning |
|---|---|---|
| C | Consumption | Households buy goods and services for their own use |
| I | Investment | Firms buy capital goods (machines, buildings). These last longer than one year. I also includes the change in stocks |
| G | Government spending | Government consumption (salaries, services) plus government investment (roads, dams) |
| X | Exports | Foreigners buy goods made at home |
| M | Imports | Subtracted, because imports are made abroad |
- Why imports are subtracted:
- Part of C, I and G is spent on imported goods. Call these parts Cₘ, Iₘ and Gₘ.
- Imports are not part of India's GDP, so they must be removed.
-
GDP ≡ (C − Cₘ) + (I − Iₘ) + (G − Gₘ) + X ≡ C + I + G + X − M, where M = Cₘ + Iₘ + Gₘ.
-
Open-economy identity: Y + M = C + I + G + X
- Left side = total supply (home output Y plus imports M).
- Right side = all the ways those goods are used.
-
Rearranged: Y = C + I + G + NX, where net exports (NX) = X − M.
-
Worked example:
- C = ₹600, I = ₹250, G = ₹150, X = ₹200, M = ₹220.
- NX = 200 − 220 = −₹20.
- Y = 600 + 250 + 150 − 20 = ₹980.
-
When imports are bigger than exports, NX is negative and pulls GDP down.
-
The sign "≡" means an identity. It is true by definition in the accounts. It is not a theory about how people behave.
Investment: why the identity always holds
- Investment is the most unstable component. Firms raise or cut it sharply when their expectations change.
- In the accounts, I has two parts:
- Planned investment: machines, buildings and stocks that firms meant to add.
-
Unplanned investment: a change in stocks (inventories) that firms did not expect. Example: goods that did not sell and stayed in the warehouse.
-
Unsold output is counted as investment in stocks:
- Suppose demand falls short of what firms produced.
- The unsold goods are recorded as an addition to stocks, which is part of I.
-
So spending always equals output ex post (after the event).
-
Valuables (gold, jewellery) are counted under investment, not consumption.
What makes expenditure-side GDP rise or fall
- Rises when households spend more (C), firms invest more (I), the government spends more (G), or exports grow faster than imports.
- Falls when any of these weaken, or when imports grow faster than exports (NX becomes more negative).
In India
- Who measures it: MoSPI (Ministry of Statistics and Programme Implementation) publishes GDP by expenditure. The main items are:
- PFCE (Private Final Consumption Expenditure): household consumption.
- GFCE (Government Final Consumption Expenditure): government spending on current goods and services, such as salaries.
- GFCF (Gross Fixed Capital Formation): spending on fixed assets such as machines, buildings and roads.
-
Change in stocks, valuables, exports, imports, and a discrepancies line.
-
New base year: MoSPI released a new GDP series with base year 2022-23 on 27 February 2026. It replaces the 2011-12 base [2][4].
- The Advisory Committee on National Accounts Statistics (ACNAS), set up in 2024, chose 2022-23 because it was a "normal" year [4].
- The years 2017-18 to 2021-22 were not used because GST and COVID-19 disturbed them [4].
-
MoSPI aims to revise the base about every five years [4].

Latest data: 2025-26 Provisional Estimates (5 June 2026), constant 2022-23 prices [3]:
| Component | ₹ lakh crore | Share of real GDP |
|---|---|---|
| PFCE | 179.94 | 55.7% |
| GFCE | 32.65 | 10.1% |
| GFCF | 104.35 | 32.3% |
| Change in stocks | 4.22 | 1.3% |
| Valuables | 3.03 | 0.9% |
| Exports | 71.65 | 22.2% |
| Imports | 76.62 | 23.7% |
| Net exports | −4.97 | ~−1.5% |
| Discrepancies | 3.90 | 1.2% |
| GDP | 323.12 | 100% |
- Total investment (GFCF + stocks + valuables) in 2025-26 was ₹111.60 lakh crore, about 34.5% of GDP (worked out from [3]).
- In 2025-26, real GDP grew 7.7%. PFCE also grew 7.7%, and GFCF grew 8.2% in real terms [3].
- PFCE was 56.5% of GDP at current prices in both 2023-24 and 2024-25 [2].
- Statistical discrepancy:
- This is the balancing item that makes expenditure-side GDP equal production-side GDP.
- India's official GDP comes from the production side. Spending data is incomplete or arrives late, so a gap remains [4].
-
The discrepancy is ₹0 in the base year 2022-23 [3]. MoSPI balanced the accounts using Supply and Use Tables (SUT), which match what is produced against how it is used [4].
-
Better data in the new series [4]:
- PFCE now draws more on the Household Consumer Expenditure Survey, the commodity flow approach (tracking goods from producers to final buyers), COICOP 2018 (a UN list that groups consumer spending by purpose) and e-Vahan vehicle data.
-
GFCE now uses actual central government spending from PFMS (Public Financial Management System), instead of Revised Estimates.
-
Old and new figures cannot be compared directly. Real GDP for 2024-25 is ₹299.89 lakh crore at 2022-23 prices [3], but ₹187.97 lakh crore at 2011-12 prices (NCERT Table 2.6).
- NCERT printing error (Table 2.6): net exports and discrepancies are printed as positive numbers. The table only adds up when both are negative (−1.61 and −2.92 lakh crore), which gives a total of ₹1,87,96,955 crore.
Don't confuse with
- Value-added (production) method: adds the value each firm adds (output minus inputs). The expenditure method adds final spending. Both give the same GDP, but India's official GDP comes from the production side [4].
- Income method: adds factor incomes (wages + profits + interest + rent). This sum equals NDP at factor cost, not GDP at market prices. You must add depreciation and net indirect taxes to reach GDP.
- Total sales: adding every firm's sales counts intermediate goods twice. In the cotton–cloth case this gives ₹250 instead of the correct ₹200.
- GFCE vs G: in NCERT's formula, G covers government consumption and government investment. In India's tables, GFCE is only current government spending (such as salaries). Government-built assets like roads are counted in GFCF.
Prelims Hooks
- GDP ≡ C + I + G + X − M, where M = Cₘ + Iₘ + Gₘ. Open-economy identity: Y + M = C + I + G + X.
- Unsold output is counted as investment (change in stocks). This is why expenditure-side GDP always equals output ex post.
- Valuables (gold, jewellery) are part of investment (capital formation), not consumption.
- PFCE is the largest component (55.7% of real GDP in 2025-26), and GFCF is second (32.3%) [3].
- Net exports are negative for India: imports were 23.7% and exports 22.2% of real GDP in 2025-26 [3].
- Current base year = 2022-23 (series released 27 February 2026). The statistical discrepancy is zero in the base year because of Supply and Use Tables [3][4].
Mains Points
- Growth led by consumption, but investment must rise:
- PFCE is about 56–57% of GDP [2][3]. This makes growth less exposed to global shocks.
- GFCF has stayed around 32% [3]. Private investment must rise for a lasting 8%+ growth rate.
-
Link this to capex-led budgets, PLI schemes and the "crowding-in" debate (whether government investment pulls in private investment).
-
Net exports drag GDP down:
- Imports are larger than exports (NX ≈ −1.5% of real GDP in 2025-26) [3]. This shows India's dependence on imports of oil, electronics and gold.
-
Valuables were 2.0% of GDP at current prices in 2025-26 [3]. This shows household savings going into gold, which does not add to productive capacity.
-
Data credibility:
- A large, changing statistical discrepancy weakens trust in any analysis based on demand-side data.
- The 2022-23 series uses SUT balancing, PFMS and e-Vahan data, and double deflation (removing price changes separately for inputs and outputs) [4]. These answer past criticism of the 2011-12 series.
- The back series (older years recalculated on the new base) is still pending and is due by December 2026 [4].
