Net Foreign Factor Income (NFFI)


Net Foreign Factor Income (NFFI) refers to the difference between the money a country’s citizens and businesses earn abroad and what foreign citizens and businesses earn within that country. It comprises income from investments and work. Therefore, positive NFFI indicates that a nation’s citizens and businesses are earning more overseas than foreigners are earning in that nation, and negative NFFI implies the opposite.


Net Foreign Factor Income (NFFI) in phonetics is pronounced as: Net: /nɛt/Foreign: /ˈfɔːrɪn/Factor: /ˈfæktər/Income: /ˈɪnkʌm/NFFI: /ˈɛn ˈɛf ˈɛf ˈaɪ/

Key Takeaways

  1. Definition: Net Foreign Factor Income (NFFI) is a measure of the net income from foreign investments. Essentially, it calculates the difference between the total economical income a country makes from its overseas investments and the total payments it makes to foreign investors investing within its territory.
  2. Relevance: NFFI is a fundamental component of the Gross National Product (GNP), which is one of the key indicators of a country’s economic performance. A positive NFFI indicates that a country has earned more from its overseas investments than it has paid out to foreign investors, which can be a sign of a strong and internationally competitive economy.
  3. Determinants: The NFFI figure can be affected by numerous factors, such as changes in exchange rates, tax laws, political stability, and the overall profitability of businesses. A more open and robust economic policy that encourages foreign investment can, in turn, boost a country’s NFFI.


Net Foreign Factor Income (NFFI) is a critical metric in macroeconomics as it helps evaluate the total income generated by a country’s domestic factors of production. This includes labor and capital on foreign soil, and income from domestic sources operated by foreign entities. Essentially, it measures the difference between the income received from overseas by citizens and businesses within a country and the income generated domestically by foreign citizens and entities. By providing this balance, NFFI enables policymakers and economists to gain insights into the economic interdependence between nations, understand the balance of trade, and evaluate the economic performance of a country. It can also influence a country’s Gross Domestic Product (GDP), thereby impacting economic strategies and policies. Thus, the importance of NFFI lies in its ability to reflect a country’s foreign economic relations and influence economic planning and decision making.


Net Foreign Factor Income (NFFI) plays a crucial role in determining a nation’s overall economic output and provides vital insights into its global financial interactions. By measuring the difference between the total economic output residents and companies of a country generate abroad and the economic output produced by foreign entities within the same country, NFFI assesses the profitability and effectiveness of a country’s international investments and its appeal to foreign investors. Moreover, NFFI is utilized to adjust Gross Domestic Product (GDP) to Gross National Product (GNP). These two metrics, while both significant indicators of economic health, offer different perspectives. GDP accounts for all income generated within a country’s borders, whereas GNP includes all income made by its nationals, regardless of geographical location, and excludes income made within its borders by foreigners. By incorporating NFFI into calculations, economists and analysts can gain a more accurate, comprehensive understanding of a country’s economic standing and performance in the global market.


1. Japan’s Automobile Industry: Japan is known for its massive automobile industry, with well-established companies like Toyota and Honda, distributing goods globally. If the profits generated by these Japanese car companies from other countries (like the U.S., Canada, or Germany) are higher than what foreign companies in Japan are earning, then Japan will have a positive Net Foreign Factor Income (NFFI). 2. Indian IT Sector: Indian IT service companies such as Tata Consultancy Services or Infosys provide software services around the world. They have many clients in the U.S. and Europe. The profits earned from these international ventures, if greater than the earnings of foreign companies operating in India, would contribute to India having a positive NFFI.3. Australian Mining Industry: Australia is a major exporter of iron ore, coal and other minerals. Much of the mining industry is owned by Australian entities. When these companies sell their resources to other nations, the revenue comes back to Australia. Additionally, Australia also has foreign companies operating in its home front. If the income from Australian companies abroad is more than foreign companies in Australia, then Australia would also have a positive NFFI.

Frequently Asked Questions(FAQ)

What is Net Foreign Factor Income (NFFI)?

Net Foreign Factor Income (NFFI) is the difference between a country’s income earned from foreign countries and the income paid to foreign entities. It helps to calculate a nation’s gross domestic product and gives a clear picture of the country’s economic performance.

How is NFFI calculated?

NFFI is calculated by subtracting the income paid to foreign entities from the income earned from overseas. The formula is: NFFI = Income from foreign countries – Payments to foreign entities.

What factors contribute to a positive NFFI?

A country may have a positive NFFI if the residents, corporations, and government of the country earn more income from foreign countries than what they pay to foreign entities. This can be through interest, dividends from foreign investments, and income from work performed overseas.

Does a negative NFFI indicate a poor economy?

Not necessarily. A negative NFFI means that the country pays more to foreign entities than it earns from foreign countries. This can be due to factors like higher investments abroad or the country being a debt importer. However, it is just one aspect of the economy and doesn’t fully determine the health of an economy.

How does NFFI affect GDP calculations?

NFFI is included in the calculation of the Gross Domestic Product (GDP) as it alters the difference between the Gross National Product (GNP) and GDP. The formula is GDP = GNP – NFFI.

How often is NFFI calculated?

Typically, NFFI is calculated on a yearly basis, during the calculation of a country’s national income account. However, for countries with large amounts of international transactions, it can also be computed on a quarterly basis.

What entities contribute to NFFI?

Various entities contribute to NFFI. These include individuals who are working overseas, businesses that have operations or investments abroad, and the government if it has foreign income.

How does NFFI vary by country?

NFFI can significantly vary by country, depending upon the respective country’s involvement in foreign trade, the economic strength of the country, and its investment in foreign entities.

Where can I find information about a country’s NFFI?

You can typically find information about a country’s NFFI in economic publications and databases, on the websites of central banks, or in the annual and quarterly economic reports released by the country’s national statistical office.
