Discuss on National Income. Gross and Net Domestic Product in detail.
Meaning of national income:- National income refers to the income which is earned by normal residents of a nation during a given period as a result of their productive services. It’s known as a national product.
Definition of national income:- According to Shapiro – National income is the sum of wages, rent, interest and profit which is received by residents of a nation in the form of income during their productive services.
National Income, Gross Domestic Product (GDP), and Net Domestic Product (NDP):
1. National Income:
Definition: National Income refers to the total value of all goods and services produced by a country’s residents (both domestic and abroad) over a specific period (usually a year), after adjusting for depreciation and indirect taxes.
Components: National Income includes:
- Wages and salaries (compensation of employees)
- Rent
- Interest
- Profits
- Mixed income of self-employed
Key Measures of National Income:
- Gross Domestic Product (GDP)
- Net Domestic Product (NDP)
- Gross National Product (GNP)
- Net National Product (NNP)
- National Income at Factor Cost
Uses of National Income:
- Indicator of economic health. Difference between gdp and ndp
- Helps in policy-making and planning.
- Basis for comparing the economic performance of countries.
- Guides investment and business decisions.
2. Gross Domestic Product (GDP):
Definition: GDP is the total market value of all final goods and services produced within a country’s borders during a given time period.
Gross Domestic Product (GDP) is the total monetary value of all goods and services produced within a country’s borders over a specific time period, usually a year or a quarter.
It’s a key indicator used to measure the size and health of a country’s economy. When GDP grows, it typically means the economy is doing well, and when it shrinks, it may indicate economic trouble. Difference between gdp and ndp

There are three main ways to calculate GDP:
- Production approach – Total value of goods and services produced.
- Income approach – Total income earned by people and businesses.
- Expenditure approach – Total spending on goods and services (consumption + investment + government spending + exports – imports0
There are three main ways to calculate GDP:
- Production approach – Total value of goods and services produced.
- Income approach – Total income earned by people and businesses.
- Expenditure approach – Total spending on goods and services (consumption + investment + government spending + exports – imports).
Types of GDP:
- Nominal GDP: Measured at current market prices.
- Real GDP: Adjusted for inflation, measured at constant prices.
Methods of Calculating GDP:
- Production Method: GDP = Value of Output – Value of Intermediate Consumption
- Income Method: GDP = Wages + Rent + Interest + Profits
- Expenditure Method: GDP = C + I + G + (X – M)
Where:
C = Consumption, I = Investment, G = Government spending, X = Exports, M = Imports Difference between gdp and ndp
Limitations of GDP:
- Doesn’t account for income inequality.
- Ignores non-market transactions (e.g., household work).
- Doesn’t consider environmental degradation.
- Excludes black market/underground economy.
3. Net Domestic Product (NDP):
Definition: NDP is GDP minus depreciation (also known as the consumption of fixed capital).
Formula: NDP = GDP – Depreciation
Explanation: Depreciation refers to the wear and tear or obsolescence of capital goods over time. NDP provides a more accurate measure of a country’s productive capacity and sustainable output. Difference between gdp and ndp
Importance:
- Gives insight into the actual productive efficiency of an economy.
- Useful for understanding long-term economic growth.
- Helps evaluate the true value of net investment in the economy.
Net Domestic Product (NDP) is an economic indicator that measures the total value of goods and services produced within a country in a given period (usually a year), after accounting for depreciation of capital goods (like machinery, buildings, etc.).
Formula:
NDP = GDP – Depreciation
- GDP (Gross Domestic Product): The total market value of all final goods and services produced within a country. Difference between gdp and ndp
- Depreciation: Also known as “consumption of fixed capital,” it’s the reduction in value of capital goods over time due to wear and tear, obsolescence, etc.
Why is NDP Important?
- It gives a more accurate measure of an economy’s actual productive capacity.
- It shows how much output is available for consumption or investment after maintaining the capital stock.
If you want, I can give examples or compare it with related terms like Net National Product (NNP) or Gross National Product (GNP).
Key Differences between GDP and NDP:
DEFINITION:
- GDP:- In gdp considered the total value of goods and services produced in the country. Difference between gdp and ndp
- NDP:- NDP refers to the value equal to the total value of final goods minus the depreciation.
- NDP = GDP – Depreciation
- GDP includes the depreciation. Difference between gdp and ndp
- Whereas NDP excludes the depreciation.
- GDP involves Broad Economic measurement.
- Whereas NDP- Focus on sustainability and net output.
Conclusion :-
Gross Domestic Product (GDP) and Net Domestic Product (NDP) are important economic indicators that help measure a country’s economic performance.
- GDP reflects the total value of all goods and services produced within a country, showing the overall economic strength.
- NDP is derived from GDP by subtracting depreciation (wear and tear of capital goods), giving a more accurate picture of the economy’s sustainable production level. Difference between gdp and ndp
In summary, GDP gives a broad overview of economic activity, while NDP provides insight into how much of that output is actually adding to the economy after accounting for the loss of value in assets. Both are crucial for understanding economic health and planning for long-term growth. You can check the syllabus of Business Economics on the official website of Gndu. Difference between gdp and ndp
