Difference Between National Income and Private Income

Download PDF 📄

The scope, components, and role are the factors that differentiate national income from private income. National income reflects the total output of a country’s economy, including all earnings that any individual in that economy receives during a particular period, including wages, profits, rents, and revenue from governments. Private income focuses on the income earned through individuals’ and privately owned businesses’ activities, including transfers like pensions and remittances. Although both metrics are essential to an understanding of an economy, distinctions between them raise some aspects of economic performance and wealth distribution.

What is National Income?

National income is the total monetary value of all final goods and services produced by the residents of a country over a specified period, mostly within one calendar year. This is, however usually considered to be an important indicator of a country’s economic performance and productivity.

National Income (NI) is calculated as:

NI or National Income= NDP at Factor Cost + Net Factor Income from Abroad

Where:

NDP: Net Domestic Product.

Key Features of National Income

Comprehensive Economic Measure: National income embraces all incomes generated both within and outside the country by residents, whether individuals, firms, or the state.
Focus on Economic Output: It counts the value of only final goods and services, thus not considering double counting for intermediate goods.
Inclusion of International Earnings: It includes international earnings in national income accounting, which accounts for the income realized from investments and employment abroad, reflecting the global economic contribution of the country.
Inclusion of Transfer Payments: Non-productive incomes such as pensions, social security, and gifts are excluded from this because these incomes are not based on any productive activity.

Components of National Income

Wages and Salaries: Remunerations earned by employees for their work.
Profits of Enterprises: Incomes generated from undertakings and industries.
Rents and Interests: Income from properties and investments.
Net Income from Abroad: Earnings from foreign investments minus payouts to foreign investors.
Government Revenues: Taxes, penalties, and payments charged by the government to give public services.

What is Private Income?

Private income is the aggregate income earned by private people and businesses in an economy during a particular period. It encompasses all the earnings from employment, business profits, and any other forms of income such as transfer payments.

Private Income is calculated as:

Private Income=National Income − Income from Government Sector + Transfer Payments

Key Features of Private Income

Exclusion of Government Revenues: Unlike national income, private income does not include earnings generated by the government through taxes, fines, or fees.
Inclusion of Transfer Payments: Private income includes non-productive incomes such as pensions, unemployment benefits, and remittances, which are excluded from national income.
Focus on Private Earnings: It highlights the financial well-being of individuals and private businesses, excluding public sector contributions.

Components of Private Income

Earned Income: Wages, salaries, and profits from business activities.
Unearned Income: Interest, rents, and dividends from private investments.
Transfer Payments: Social security benefits, pensions, and remittances received from family members abroad.

Difference Between National Income & Private Income

Although national income and private income are interconnected, they differ significantly in terms of scope, components, and application. Here is a detailed comparison:

Scope

National Income: National income gives a comprehensive view of the economy, including contributions from all sectors public and private, and earnings from abroad. It covers the total economic output due to residents, whether in the form of individual persons, private businesses, or the government itself.
Private Income: Private income is a relatively narrow concept, concentrating solely on the income earned by private individuals and enterprises. It excludes the revenues generated by the government and public sector entities and therefore represents a subset of national income.

Components

National Income: National income includes wages, profits, rents, interest, and government revenues. It reflects all earnings arising from productive activities within the economy.
Private Income: Private income comprises wages, profits, rents, interest, and transfer payments like pensions and remittances. While it includes unearned incomes, it excludes public sector revenues.

Transfer Payments

National Income: National income does not account for transfer payments since these have no direct linkage to productive activities. Examples of such payments are social security benefits or remittances, for which no resultant effect comes from economic output.
Private Income: Transfer payments are a significant component of private income. They improve the disposable income of the individuals and are included despite not being directly related to production.

Measure of Wealth

National Income: National income is a macroeconomic indicator that reflects the total wealth and productivity of the nation. It is used to assess the overall economic performance and growth trends.
Private Income: Private income measures the earnings and financial status of private individuals and enterprises. It offers insights into consumer spending power and private sector contributions.

Role in Economic Planning

National Income: National income is important data used by governments to devise fiscal and monetary policies, determine economic targets, and distribute resources in each sector. It is thus necessary for macroeconomic planning and development.
Private Income: Private income helps the policymaker understand consumer behavior, savings patterns, and the role of the private sector in driving the economy. It comes in handy for formulating tax and welfare policies.

Conclusion

The distinction between national income and private income reveals two different factors of measurement of economic activity and wealth. National income gives an all-around view of the economic development of a nation, encompassing all sectors and productive activities. Whereas private income measures the income earned by individuals and private enterprises, providing a narrow viewpoint of consumer purchasing capacity as well as private sector contribution.
