Difference between GNP GDP and GNI

Difference between GNP GDP and GNI

Reading Time: 4 minutes

In macroeconomics, several metrics are utilized to measure a country's economic activity and overall well-being. Gross Domestic Product (GDP), Gross National Product (GNP), and Gross National Income (GNI) are three widely-used measures that provide insights into a country's economic growth, output, and standard of living. 

This article highlights the distinctions between these metrics, emphasizing their relevance and usage in analyzing economic development.

GDP and Its Significance

Gross Domestic Product (GDP) represents the total value of all goods and services produced within a country's borders during a specific period. 

It is a widely used indicator to measure a country's economic output. Economists and policymakers can assess the economic growth and overall health of a nation's economy by evaluating GDP.

The metric is made up of four main economic activities, including government spending, investment, household spending, and net exports (exports minus imports).

GDP Formula:





G=Government Spending

X=Net Exports

GNP and Its Distinctions

On the other hand, Gross National Product (GNP) focuses on the total income earned by a country's residents, both within and outside its borders, during a specific time frame.

GNP considers the income generated by citizens of a country, irrespective of their location. It means that it includes the income generated by citizens living abroad whilst excluding the income earned by foreign residents within the country.

Gross National Product Formula:

GNP = C+ I + G + X + Z or GNP = GDP + Z


C = Consumption

I = Investment

G = Government Expenditure

X = Net Exports (Value of imports - value of exports)

Z = Net Income ( Net income inflows from abroad- net income outflows to foreign countries)

GNP captures the national economy's overall performance and helps analyze the economic well-being of a country's citizens.

GNI and Its Comprehensive Nature

Gross National Income (GNI) is a broader metric encompassing GDP and GNP. It reflects the total income a country's residents receive, including net factor income from abroad.

GNI accounts for net income receipts, which are the difference between income earned from foreign investments and the income flowing out of the country.

GNI Formula:



GNI= Gross National Income

GDP=Gross Domestic Product

EXFS=Money flowing from foreign countries

IMFS=Money flowing from foreign countries

This measure provides a comprehensive understanding of a country's economic activity and citizens' total income, regardless of residency.

Comparing GDP, GNP, and GNI

Whilst all three metrics—GDP, GNP, and GNI—contribute to understanding a country's economic development, their distinct characteristics and focus set them apart. 

  • GDP concentrates solely on economic activity within a country's borders and disregards the nationality of those involved. 
  • GNP focuses on the income a country's residents generate, regardless of location. 
  • GNI offers the most comprehensive perspective by accounting for GDP and GNP, incorporating the net factor income from abroad.

The Role of National Accounts

National accounts play a crucial role in determining these metrics. National accounts are records that capture and compile data on a country's economic activities, including production, income, and expenditure.

These accounts provide each factor for calculating GDP, GNP, and GNI, enabling policymakers and economists to assess economic performance and make informed decisions about how to proceed to maintain the health of their own economy.

GDP per Capita and Standard of Living

One valuable application of GDP, GNP, and GNI is the calculation of per capita figures. Dividing these metrics by a country's population yields GDP per capita, GNP per capita, and GNI per capita, respectively.

These figures give insights into each individual's average economic output and income, aiding in comparing the standard of living across different countries. It is important to note that whilst these figures are informative, they may only partially represent a nation's wealth distribution. It’s also important to note that these figures in a vacuum do not provide the whole picture as averages may not show skewed distributions of wealth, and nominal figures do not account for things like inflation or correct for cost of living. For these reasons, more complex methods can be used to get a more accurate picture of living standards. Examples include inflation-adjusted or “real” figures. Purchasing power parity can be used to account for the cost of living and get a more accurate depiction of overall living standards regardless of nominal value.

Considering Depreciation and Net Exports

In calculating GDP, GNP, and GNI, depreciation, and net exports play significant roles. 

Depreciation represents the wear and tear of capital goods over time, and it is deducted from GDP to obtain Net Domestic Product (NDP). Similarly, net exports (exports minus imports) are incorporated in GDP calculations to account for the impact of international trade.

These adjustments provide a more accurate reflection of a country's economic performance.


GDP helps to monitor the overall output of a country's economy. It is generally used to measure whether an economy is growing or experiencing a recession.

GNP does a better job of measuring the economic well-being of a country’s citizens as it includes income from abroad, rather than just what is produced within the borders of the country.

GNI provides an understanding of the growth or decline of an economy over a range of years. It measures an economy's ability to maintain minimum production standards, i.e., consistently providing a national output of goods and services.


In summary, GDP, GNP, and GNI are crucial metrics that offer unique perspectives on a country's economic activity, growth, and citizens' income.

Whilst GDP measures the total value of goods and services produced within a country's borders, GNP focuses on the income generated by its residents, regardless of their location.

GNI provides a comprehensive picture by incorporating both GDP and GNP, encompassing net factor income from abroad.

Understanding these distinctions is essential for policymakers, economists, and researchers to gain comprehensive insights into a country's economic development, standard of living, and overall well-being.
