# WHAT ARE THE METHODS OF CALCULATING NATIONAL INCOME

## METHODS OF CALCULATING NATIONAL INCOME

2. Expenditure method
3. Income method
4. In India, The Central Statistics Office (CSO) calculates India’s GDP. It comes under the Ministry of Statistics and Program Implementation (MOSPI). It gathers data and maintains statistical records.
5. On May 23, the government announced that the National Sample Survey Office (NSSO) will be merged with the Central Statistics Office to form the National Statistical Office (NSO).
6. The expenditure method has the capacity to calculate illegal income.
7. In 1999 national income from the expenditure method was 10 times more than the income method.

## VALUE ADDED METHOD

• Value-added means the addition of value-added to raw material by the firm by productive activities.
• The value-added method gives GVAMP and the sum of GVAMP of all the sectors gives GDPMP.
• The value-added method is also known as product method, inventory method, net output method, industrial origin method, commodity service method.

Value added or GVAMP = value of output – intermediate consumption

• Intermediate consumption refers to the value of input used by a firm to produce goods and services. Also known as the purchase of raw material.

Intermediate consumption= domestic purchase+ imports+ any other charge or expenditure made by firm during production

• Value of output refers to market value of goods and services produced during a period of one year.

Value of output= sales+ change in stock+ drawings of the product

OR

Value of output= (quantity × price) + change in stock

• Sales refers to total units sold by firm in a year.

Sales= sales A + sales B + sales C ……. + domestic sales + exports

• Drawings refer to products used by producers from production for self-consumption.
• Change in stock refers to the difference between closing and opening stock.

Change in stock= closing stock- opening stock

## PRECATIONS OF VALUE ADDED METHOD

1. INTERMEDIATE GOODS ARE NOT INCLUDED IN NATIONAL INCOME: the value of intermediate goods is already included in the value of final goods. If they are included again, it will lead to the problem of double counting.
2. SALES AND PURCHASE OF SECOND-HAND GOODS IS NOT INCLUDED IN NATIONAL INCOME: value of these goods were included in the year they were produce.
3. BROKERAGE OR COMMISSION ON SALES OF SECOND-HAND GOOD IS INCLUDED IN NATIONAL INCOME
4. PRODUCTION OF SERVICES FOR SELF-CONSUMPTION IS NOT INCLUDED IN NATIONAL INCOME: domestic services like service of homemade, kitchen gardening, etc. are not included in national income is it is difficult to measure their market value. Services of maid, driver, private tutors, etc. are included in national income.
5. PRODUCTION OF GOODS AND SERVICES FOR SELF-CONSUMPTION IS INCLUDED IN NATIONAL INCOME: as they contribute to current output.
6. IMPUTED VALUE OF OWNER-OCCUPIED HOUSES IS INCLUDED IN NATIONAL INCOME
7. CHANGE IN INVENTORY IS INCLUDED IN NATIONAL INCOME

DOUBLE COUNTING: it refers counting of an output more than once while calculating national income.

## HOW TO PREVENT PROBLEM OF DOUBLE COUNTING?

1.  Final output method: the only value of final goods should be added to determine national income.
2. Value-added method: sum of value added by each productive unit should be taken while estimating national income.

## INCOME METHOD

• According to this method, all the income generated through the factor of production( rent, wages, profit, and interest ) is summed to get national income.
• It gives NDPFC.
• System of national accounts (SNA) 1993 elaborated components of income method.
• This method is also known as the distributive share method and factor payment method.

Profit= corporate tax + dividend + retained earnings

•  MIXED INCOME: income generated by own account workers or self-employed.

OPERATING SURPLUS: it refers to sum of income from property and entrepreneurship.

Operating surplus = rent and royalty + interest + profit

Income method (NDPfc) = compensation of employees + rent and royalty + interest + profit + mixed income

OR

Income method (NDPfc) = compensation of employees + operating surplus + mixed income

Expenditure method (GDPMP): Private Final Consumption Expenditure + Government Final Consumption Expenditure + Gross Domestic Capital Formation + Net Exports (X-M)
