GDP Calculation 

GDP (Gross Domestic Product) can be calculated using three main approaches, each focusing on a different aspect of economic activity. These approaches are known as the expenditure approach, income approach, and production (value-added) approach. Here’s a brief overview of each method:

Expenditure Approach

This approach calculates GDP by summing up the total expenditure on goods and services within a country during a specific time period. It accounts for four major components:

• Personal Consumption Expenditure (C): Spending by households on goods and services.
• Gross Private Domestic Investment (I): Investment in capital goods, residential structures, and business inventories.
• Government Consumption and Investment (G): Government expenditure on goods and services.
• Net Exports (X – M): The difference between exports (X) and imports (M).

GDP = C + I + G + (X – M)

Income Approach

This approach calculates GDP by summing up the total income generated in the economy during a specific time period. It accounts for various types of income, including wages, salaries, profits, rents, and interest.

GDP = Compensation of Employees + Rents + Interest + Profits + Taxes – Subsidies + Depreciation

Production (Value-Added) Approach

This approach calculates GDP by adding up the value-added at each stage of production within an economy. It focuses on the incremental value created by each producer in the production process and avoids double-counting.

GDP = Value Added by all Industries + Taxes – Subsidies

GDP Calculation in India Since 2015

Changes in GDP Calculation Methodology in India since 2015 for National Income:

Change of Base Year

The base year for GDP calculation was changed from 2004-2005 to 2011-2012, following the recommendation of the National Statistical Commission. There is now consideration to change the base year again to 2017-18.

Replacement of Factor Cost with Market Prices

GDP is now measured using the gross value added (GVA) method at basic prices, rather than at factor cost. Industry-wise estimates are presented as GVA at basic prices, while GDP at market prices is referred to as GDP.

Alignment with International Practices

The new GDP methodology follows the international practice recommended by the United Nations System of National Accounts in 2008. This ensures the comparability of India’s GDP Growth numbers with those of developed nations in the future.

Broadening of Data Pool

The earlier data was based on the Annual Survey of Industries (ASI), which covered around two lakh factories. However, the new methodology incorporates data from the Ministry of Corporate Affairs (MCA21), including more than five lakh registered companies. This expanded data pool provides a more comprehensive view at the enterprise level, moving beyond the factory-level perspective.

Improved Coverage of Financial Corporations

The revised GDP calculation includes a wider range of financial corporations such as stock brokers, stock exchanges, asset management companies, mutual funds, pension funds, and regulatory bodies like SEBI, PFRDA, and IRDA. This enhanced coverage ensures a more accurate representation of the financial sector’s contribution to GDP.

Changes in Calculation of Agricultural Income

The calculation of agricultural income now includes not only value addition in farm produce but also value addition in livestock. For example, the value added to by-products of meat, such as the head, skin, and legs, is now included in the calculation. These changes in GDP calculation methodology aim to improve accuracy, align with international standards, capture a more comprehensive picture of economic activity, and reflect the evolving structure of the Indian Economy
