Frequently Asked Questions
What is the difference between GDP at Market Price and GDP at Factor Cost?
GDP at Market Price includes indirect taxes and excludes subsidies, reflecting the actual prices paid by consumers. GDP at Factor Cost measures the income received by the factors of production, calculated by subtracting Net Indirect Taxes from GDP at Market Price.
Why are intermediate goods excluded from the calculation of National Income?
Intermediate goods are used as raw materials in the production of other goods. Including them would lead to the problem of double counting, which artificially inflates the value of national income.
What is the difference between Real GDP and Nominal GDP?
Nominal GDP is calculated using current year prices and can fluctuate due to inflation. Real GDP is calculated using a base year's constant prices, making it a true indicator of economic growth as it reflects changes in physical output only.
