GDP measures economic production within a country's territory. GNP, traditionally called Gross National Product, focuses on production income associated with its resident economy. Learn how they differ, how to calculate them, and why economists use both measures.
GDP Focus
Domestic Production
Production taking place within India's economic territory contributes to India's GDP, subject to national accounting rules.
GNP / GNI Focus
Net Primary Income
Adds primary income received from abroad and subtracts primary income paid abroad.
GDP and GNP are related measures of economic activity, but they answer different questions. One focuses on the location of production; the other adjusts GDP for primary income flows between the domestic economy and the rest of the world.
Gross Domestic Product
GDP is the value of final goods and services produced within a country's economic territory during a specified period, usually a quarter or a year.
Main Question
Where was the production carried out?
A foreign-owned factory operating in India contributes to India's GDP because its production takes place in India.
Gross National Product / Gross National Income
GNP is the traditional term for a closely related gross national measure. Modern national accounts commonly use GNI, which adjusts GDP for net primary income from abroad.
Main Question
What primary income accrues to resident units?
Income received by Indian residents from foreign investments can increase India's GNI, while primary income payable to non-residents can reduce it relative to GDP.
Important Terminology
GNP is often taught in textbooks, while GNI is commonly used in modern national accounts. The formula below uses GNI, the modern national-income measure corresponding to the traditional GNP concept. National accounts use residence rules, not simply citizenship or a company's brand name.
Imagine an economy connected to the rest of the world through wages, interest, dividends, and other primary income flows. GDP measures domestic production first; GNI then adjusts that figure for net primary income flows.
Goods and services produced within India's economic territory.
Income received from abroad minus income payable abroad.
GDP adjusted for the net primary income flow.
GNI = GDP + Primary Income Received From Abroad − Primary Income Paid Abroad
If receipts exceed payments, GNI is higher than GDP. If payments exceed receipts, GNI is lower than GDP.
To calculate the national gross measure, start with GDP and adjust it for primary income transactions between residents and the rest of the world.
GDP Formula
GDP = Domestic Production Value
In practice, national statisticians calculate GDP through production, expenditure, and income approaches, using national accounting rules to avoid double counting.
GNI / Traditional GNP Formula
GNI = GDP + Net Primary Income From Abroad
Net primary income includes relevant cross-border compensation of employees and property income, such as interest and dividends, under national accounting rules.
Do Not Confuse Income With Remittances
Money sent home by a relative working abroad is not automatically primary income. Personal remittances are generally classified as transfers, not primary income, and therefore are not simply added to GNI. The classification depends on the nature of the payment and the relevant residence rules.
These fictional examples use realistic types of economic transactions to demonstrate the calculation. The figures are illustrative and are not official Indian statistics.
Suppose a fictional country has domestic production worth ₹100 lakh crore. Residents receive ₹4 lakh crore of primary income from abroad, while ₹9 lakh crore of primary income is payable to non-residents.
GDP
₹100 lakh crore
Income Received
₹4 lakh crore
Income Payable
₹9 lakh crore
Step-By-Step Calculation
Net primary income from abroad = ₹4 − ₹9 lakh crore
Net primary income = −₹5 lakh crore
GNI = GDP + Net primary income from abroad
GNI = ₹100 − ₹5 = ₹95 lakh crore
In this example, GDP is higher than GNI because more primary income is payable abroad than received from abroad.
Now suppose another fictional country has GDP of ₹80 lakh crore. Its residents receive ₹7 lakh crore in primary income from abroad and pay ₹3 lakh crore to non-residents.
Calculation
Net primary income = ₹7 − ₹3 = ₹4 lakh crore
GNI = ₹80 + ₹4 lakh crore
GNI = ₹84 lakh crore
Here, GNI is higher than GDP because the country receives more primary income from abroad than it pays to non-residents.
The following examples explain how the concepts apply in the real world. They describe the direction of the accounting effect, not the actual value of a particular company's contribution.
Imagine a foreign company operating a factory in India. The factory's production contributes to India's GDP because the production takes place in India.
GDP Effect
Production in India is included in India's GDP.
GNI Effect
Primary income payable to non-resident owners can make India's GNI lower relative to GDP, all else equal.
Suppose an Indian resident receives interest or dividends from an eligible overseas investment. The income may count as primary income received from abroad under national accounting rules.
GDP Effect
The overseas production itself is not added to India's GDP merely because an Indian resident receives investment income.
GNI Effect
The eligible primary income received can increase India's GNI relative to GDP, all else equal.
A worker living abroad may send money to family in India. Such remittances are generally classified as transfers rather than primary income.
Key Lesson
Do not automatically add all remittances to GNI. The worker's residence status and the nature of the payment matter.
An Indian-headquartered group may own a subsidiary producing goods in another country. The subsidiary's production generally contributes to that country's GDP, because the subsidiary is usually a resident producer there.
Key Lesson
The overseas subsidiary's output is not automatically part of India's GDP. Certain primary income accruing to Indian residents may affect India's GNI.
Note: International accounting distinguishes resident units from non-resident units. Ownership, incorporation, tax status, and residence can interact in complex ways; the examples above are simplified explanations.
Neither measure answers every economic question. GDP is central to understanding domestic production, while GNI helps show how cross-border primary income changes the income associated with the resident economy.
Example
A country with large payments of investment income to non-residents may have GNI below GDP. GDP alone does not show that difference.
Example
A country can receive substantial primary income from abroad, but policymakers still need GDP and sector data to understand production and employment inside the country.
GDP helps explain domestic production; GNI helps explain the effect of net primary income flows on national income. Using both gives a fuller picture than relying on either indicator alone. For living standards, also examine real per-capita income, inequality, employment, and other social indicators.
| Basis | GDP | GNP / GNI |
|---|---|---|
| Main focus | Domestic production | GDP adjusted for net primary income from abroad |
| Core question | Where did production occur? | What primary income accrues to resident units? |
| Starting point | Value of domestic production | GDP plus net primary income from abroad |
| Foreign-owned factory in India | Its Indian production contributes to GDP | Income payable to non-resident owners can affect GNI |
| Primary income received from abroad | Not added to GDP just because it is received | Added, subject to national accounting rules |
| Primary income paid abroad | Not directly subtracted from GDP | Subtracted in calculating GNI |
| Best use | Domestic output and economic growth | National income and cross-border primary income flows |
Both measures are useful, but neither tells the complete story of a country's economic well-being.
A high GDP or GNI does not mean income is shared equally among residents.
A large total figure does not reveal average output or income per person.
Many unpaid household activities are not included in GDP in the same way as market production.
Economic production can rise even when pollution or environmental damage also increases.
Nominal figures can rise because prices rise, so real measures are important for growth comparisons.
Neither indicator directly measures health, education, leisure, personal wealth, or quality of life.
GNP is the traditional term for a gross national product measure. Modern national accounts commonly use GNI, which is GDP adjusted for net primary income from abroad. Terminology and presentation can vary by statistical framework.
Yes. If primary income received from abroad exceeds primary income payable to non-residents, GNI can be higher than GDP.
Yes. If primary income payable abroad exceeds primary income received from abroad, GNI can be lower than GDP.
Not automatically. Remittances are generally classified as transfers rather than primary income. Whether a payment affects GNI depends on its nature and the residence status of the people or units involved.
Neither is universally more important. GDP is essential for measuring domestic production; GNI helps explain net primary income flows. Economists choose the measure that fits the question.
Not necessarily. Total GDP can rise because the population grows or because prices rise. Real GDP per capita, income distribution, wages, and other indicators help provide a fuller picture.
