National Income = Rent + Wages + Interest + Profit + Mixed-Income

Expenditure Method:

The expenditure method of calculating national income focuses on expenditures. Now expenditure refers to all the purchases made by residents, government, or business enterprises.

Hence, according to the expenditure method:

National Income = C + G + I + NX

Value-Added Method:

The value-added method of calculating national income focuses on the value added to a product at each stage of production.

Hence, according to the value-added method:

National Income = (NDPFC) + Net factor income from abroad
