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, whereas GDP at Factor Cost reflects the actual earnings of factors of production by excluding Net Indirect Taxes.
Why are intermediate goods excluded while calculating National Income?
Intermediate goods are used up in the production of other goods. Excluding them avoids the problem of double counting, ensuring that only the value of final goods is measured.
How do we convert Gross values into Net values?
By subtracting depreciation (consumption of fixed capital) from the Gross value, you obtain the Net value.
