GDP, GNP, NNP
GDP, GNP, NNP
1. Definitions and Concepts
GDP (Gross Domestic Product)
- Definition: Total value of all final goods and services produced within a country’s borders in a given period (usually a year).
- Scope: Domestic production, regardless of ownership.
- Purpose: Measure of economic activity and standard of living.
GNP (Gross National Product)
- Definition: Total value of all final goods and services produced by a country’s residents, regardless of where they are produced.
- Scope: National ownership, includes income earned abroad.
- Purpose: Measure of economic output from a country’s citizens.
NNP (Net National Product)
- Definition: GNP minus depreciation (i.e., consumption of fixed capital).
- Scope: Net income from national output after accounting for capital depreciation.
- Purpose: Reflects the net income available for consumption and saving.
2. Calculations at Factor Cost and Market Price
A. Factor Cost Method
| Concept | Definition | Formula |
|---|---|---|
| GDP at Factor Cost | Total value of goods and services produced by all factors of production (land, labor, capital, enterprise) | GDP at Factor Cost = Wages + Rent + Interest + Profit |
| GNP at Factor Cost | Total income earned by the factors of production of a country’s residents | GNP at Factor Cost = Wages + Rent + Interest + Profit (from abroad) |
| NNP at Factor Cost | GNP at Factor, Cost minus depreciation | NNP at Factor Cost = GNP at Factor Cost - Depreciation |
B. Market Price Method
| Concept | Definition | Formula |
|---|---|---|
| GDP at Market Price | Total value of goods and services produced within a country at market prices | GDP at Market Price = GDP at Factor Cost + Indirect Taxes - Subsidies |
| GNP at Market Price | Total value of goods and services produced by a country’s residents at market prices | GNP at Market Price = GNP at Factor Cost + Indirect Taxes - Subsidies |
| NNP at Market Price | GNP at Market Price minus depreciation | NNP at Market Price = GNP at Market Price - Depreciation |
3. Key Differences
| Concept | GDP | GNP | NNP |
|---|---|---|---|
| Definition | Domestic production | National ownership | Net national income |
| Scope | Within the country | By residents | After depreciation |
| Formula | GDP = C + I + G + (X - M) | GNP = GDP + Net Income from Abroad | NNP = GNP - Depreciation |
| Focus | Location | Ownership | Net income |
4. Important Terms and Concepts
- Factor Cost: Price paid to the factors of production (land, labor, capital, enterprise).
- Market Price: Price at which goods and services are sold in the market.
- Indirect Taxes: Taxes on goods and services (e.g., sales tax, excise duty).
- Subsidies: Government financial assistance to producers.
- Depreciation: Reduction in the value of capital assets due to wear and tear.
- Net National Product (NNP): Net income available for consumption and saving after depreciation.
5. Commonly Asked Questions (SSC, RRB)

6. Examples
GDP at Factor Cost
- A factory in India produces 100 units of goods. Wages = ₹50,000; Rent = ₹20,000; Interest = ₹15,000; Profit = ₹15,000.
- GDP at Factor Cost = ₹100,000
GNP at Market Price
- A company in India earns ₹100,000 from domestic sales and ₹20,000 from foreign sales. Indirect taxes = ₹10,000; Subsidies = ₹5,000.
- GNP at Market Price = (₹100,000 + ₹20,000) + ₹10,000 - ₹5,000 = ₹125,000
NNP at Factor Cost
- GNP at Factor Cost = ₹125,000; Depreciation = ₹10,000
- NNP at Factor Cost = ₹125,000 - ₹10,000 = ₹115,000
7. Summary Table
| Concept | Formula | Notes |
|---|---|---|
| GDP at Factor Cost | Wages + Rent + Interest + Profit | Measures income earned by factors within the country |
| GNP at Factor Cost | Wages + Rent + Interest + Profit (from abroad) | Measures income earned by residents |
| NNP at Factor Cost | GNP at Factor Cost - Depreciation | Net income after depreciation |
| GDP at Market Price | GDP at Factor Cost + Indirect Taxes - Subsidies | Reflects market value of output |
| GNP at Market Price | GNP at Factor Cost + Indirect Taxes - Subsidies | Reflects market value of national output |
| NNP at Market Price | GNP at Market Price - Depreciation | Net income after depreciation and taxes |
