National Income Calculator

Calculating national income is an essential task for understanding the economic health and productivity of a country. It encompasses various components that reflect both domestic and international economic activities.

Historical Background

National income accounting is a critical aspect of macroeconomics that helps in assessing a country's economic performance. It originated in the 20th century as economists sought better ways to measure economic activity, especially to guide recovery efforts during and after economic downturns such as the Great Depression.

Calculation Formula

To compute the national income, the formula is as follows:

\[ NI = C + GE + I + E - IM + FPNR - DPBNR \]

where:

• \(NI\) is the national income,
• \(C\) is the total consumption,
• \(GE\) is the government expenditures,
• \(I\) is investments,
• \(E\) is exports,
• \(IM\) is imports,
• \(FPNR\) is foreign production by national residents,
• \(DPBNR\) is domestic production by non-national residents.

Example Calculation

Suppose a country has the following economic indicators:

• Total consumption: $500 billion
• Government expenditures: $300 billion
• Investments: $200 billion
• Exports: $100 billion
• Imports: $50 billion
• Foreign production by national residents: $20 billion
• Domestic production by non-residents: $10 billion

Using the national income formula:

\[ NI = 500 + 300 + 200
