Question

Why do we take value added in estimating national income?

Answer 1

We take value added in estimating national income to ensure that the income is calculated accurately without double counting. National income is the total value of final goods and services produced in an economy. Since many goods pass through different stages of production and involve multiple enterprises, simply adding all outputs would overstate the income due to the repetition of intermediate goods’ values.

Value added refers to the net contribution of each enterprise, calculated as:

Net Value Added at Factor Cost = Gross Output − Intermediate Consumption − Depreciation − Net Indirect Taxes

By taking the value added by each production unit, we avoid including the same product’s value multiple times and ensure that only newly created value is counted, giving a correct estimate of national income.
