The difference between national income and disposable income lies in the tax and transfer payment components. National income represents the total income earned by all factors of production within an economy, while disposable income is the amount of income available for consumption, saving, or investment after accounting for personal income taxes and transfers.

National Income:

  • It is the total income earned by all factors of production within an economy.
  • It includes compensation of employees, corporate and government enterprise profits before taxes, interest income, unincorporated net income of businesses, rent, indirect business taxes, and subsidies.
  • National income is calculated as follows: National Income = Compensation of employees + Corporate and government enterprise profits before taxes + Interest income + Unincorporated net income of businesses + Rent + Indirect business taxes – subsidies.

Disposable Income:

  • It is the amount of money that a population has left after paying personal income taxes and other direct taxes.
  • Disposable income represents the actual amount of money available for households to spend on goods and services, save, or invest.
  • It is calculated by subtracting personal income taxes and other direct taxes from personal income.

In summary, national income represents the total income earned by all factors of production within an economy, while disposable income represents the actual amount of money available for households to spend on goods and services, save, or invest after accounting for personal income taxes and transfers.
