System of National Accounts & GDP Concepts
GDP = C + I + G + (X–M). Three ways to compute it. GDP vs GNP vs NDP vs NNP — what’s the difference? Real vs Nominal GDP, GVA vs GDP, Factor Cost vs Market Price. This chapter demystifies how India measures its economy’s size.

National accounts are the scoreboard of the economy — and your bank’s performance
Section 4 — Key Definitions and Concepts
SNA framework, three GDP computation methods, all variants — from the textbook
The System of National Accounts (SNA) is a coherent, consistent and integrated collection of macroeconomic accounts, balance sheets and tables based on internationally agreed concepts, definitions, classifications and accounting principles. Countries use the SNA developed by the United Nations for global uniformity. All UN member nations are advised to prepare and report National Accounts Statistics (NAS) in accordance with the 2008 SNA (updated version of the 1993 SNA). In India, the GDP Series Base Year was amended from 2004-05 to 2011-12 and issued on January 30, 2015, following the adoption of SNA 2008 sources and techniques. Key change: Headline growth rate now measured by GDP at constant market prices (previously at factor cost). GVA at basic prices replaced GDP at factor cost in sectoral estimates.
Gross Domestic Product (GDP) is the total market value of all the final goods and services produced within the territorial boundary of a country, using domestic resources, during a given period of time, usually one year. GDP does NOT include value of intermediate goods and services. May be produced by private or public sector. Three ways to compute: (1) Expenditure method: GDP = C + I + G + (X – M) where C = consumption, I = investment, G = government spending, X–M = net exports. (2) Income approach: sum of compensation of employees + property income + production taxes and depreciation. (3) Product/Output/Value-added method: Sum of value added across all sectors.
All three methods yield the same GDP value — they just measure from different angles (spending, income, production)
All National Income Aggregates — Definitions and Formulae
GDP — Gross Domestic Product
Does NOT differentiate owners of factors of production. Includes production by foreign companies within India. Does NOT include intermediate goods.
GNP — Gross National Product
Measures value of final goods/services produced by nationals of an economy regardless of where production takes place. Includes Indian-owned business in USA. When income from abroad is included in GDP, it becomes GNP.
NDP — Net Domestic Product
Deducts depreciation (wear and tear of factory machines, office equipment) from GDP. Net means after accounting for capital consumption (depreciation). Alternatively: GDP = NDP + Depreciation
NNP — Net National Product
Also called National Income at Market Prices. Deducts depreciation from GNP. NDP = NNP – NFIA. NNP = NDP + NFIA. National Income (NI) = NNP at Factor Cost.
GNI — Gross National Income
More comprehensive than GNP. Accounts for all primary income flows between residents and non-residents.
GVA — Gross Value Added
GVA measures value of goods/services produced in an area/industry less intermediate consumption. GVA better for comparing SECTORS within economy. GDP better for COMPARING ECONOMIES. GVA at Basic Prices = GVA at factor cost + Production taxes – Production subsidies.
Factor Cost vs Basic Price vs Market Price
| Price Concept | Definition | Formula |
|---|---|---|
| Factor Cost | Total cost of all factors of production consumed in producing a good/service (wages, rent, interest, profit) | GDP at Factor Cost = GDP at Market Prices – Net Indirect Taxes (= indirect taxes – subsidies) |
| Basic Price | Amount receivable by producer from purchaser minus any tax payable plus any subsidy receivable on production or sale | Basic Price = Factor Cost + Production taxes – Production subsidies |
| Market Price | Economic price at which a good or service is offered in the marketplace. Includes taxes imposed and subsidies provided by government | Market Price = Basic Price + Product taxes – Product subsidies |
| Real GDP | Value of today’s output at BASE YEAR (yesterday’s) prices — removes inflation impact. Reflects real growth in volume. | Real GDP = Nominal GDP / GDP Deflator × 100 |
| Nominal GDP | Value of today’s output at TODAY’S current market prices. Simply current year output × current year prices. | Nominal GDP = Output × Current Year Prices |
Complete Formulae — All National Income Aggregates
| Aggregate | Formula | Key Note |
|---|---|---|
| GDP = C + I + G + (X-M) | Private consumption + Gross investment + Govt spending + Net exports | Expenditure method | Demand side |
| NDP | GDP – Depreciation | Net of capital consumption |
| GNP | GDP + NFIA | NFIA = Net Factor Income from Abroad |
| NNP (= National Income at MP) | GNP – Depreciation | Also = NDP + NFIA |
| National Income (NNP at FC) | NNP at MP – Net Indirect Taxes (= indirect taxes – subsidies) | Also written NI = NNP_fc |
| GDP at FC | GDP at MP – Net Indirect Taxes | Factor cost = removes tax/subsidy distortions |
| GVA at Basic Prices | GVA at Factor Cost + Production taxes – Production subsidies | New measure replacing GDP at factor cost (since 2011) |
| GDP at MP | GVA at Basic Prices + Product taxes – Product subsidies | Headline GDP measure |
| GDP Deflator | (Nominal GDP / Real GDP) × 100 | Quarterly | Comprehensive | No fixed basket |
| Personal Income | Private Income – Undistributed profits – Corporate profits – Retained foreign earnings – Taxes | Income actually received by individuals |
| Personal Disposable Income (PDI) | Personal Income – Personal taxes – Direct taxes – Fines/fees | Available for actual consumption |
| Operating Surplus | Rent + Interest + Profit + Dividend | Capital’s share of income |
| GNDI (Gross National Disposable Income) | GNP at MP + Net current transfers from rest of world | Broader than GNP |
| NDP at FC | NDP at MP – Net Indirect Taxes | = Compensation of Employees + Operating Surplus + Mixed Income |
(1) GDP is aggregate — doesn’t show distribution: A country may have high GDP but skewed income distribution. Per capita income also doesn’t indicate distribution pattern. (2) Regional disparity: Few developed states contribute most of GDP, majority contribute meagre — visible in India. (3) Higher GDP ≠ higher welfare: Welfare encompasses health, education, sanitation — all not captured by GDP. India has grown GDP but social indicators lag. Should be supplemented by HDI. (4) For export-oriented economies: GDP doesn’t reflect total income — GNP is more accurate as it includes external earnings. (5) GDP doesn’t show financial inclusion: Financial exclusion is a global challenge not reflected in GDP. (6) Green GDP emerging: Traditional GDP doesn’t capture environmental degradation — “Green GDP” concept being developed globally.
