Types of GDP
There are several different types of approaches to calculating GDP, each focusing on a specific aspect of economic activity. Here are some commonly recognized types of GDP:
|Nominal GDP||Nominal GDP measures the value of goods and services produced at current prices without adjusting for Inflation.|
|Real GDP||Real GDP adjusts for inflation by measuring the value of goods and services produced using constant base-year prices. It provides a more accurate reflection of changes in production levels over time.|
|Gross Domestic Income (GDI)||GDI measures the total income generated by the production of goods and services within a country’s borders. It includes employee compensation, business profits, rental income, and net interest.|
|Gross National Product (GNP)||GNP measures the total value of goods and services produced by a country’s residents, both domestically and abroad. It includes income earned by residents from foreign sources and excludes income earned by foreigners within the country.|
|Purchasing Power Parity (PPP) GDP||PPP GDP adjusts GDP figures to account for differences in the cost of living between countries, allowing for more accurate international comparisons of economic output.|
|Per Capita GDP||Per Capita GDP is calculated by dividing the total GDP of a country by its population. It provides an average measure of economic output per person and is often used to compare living standards between countries.|

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:
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)
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.

Real and Nominal GDP
Here is a table that give a comparative analysis of these two concepts.
|Nominal GDP||Real GDP|
|Definition||Value of goods and services produced using current market prices||Value of goods and services produced using constant base-year prices adjusted for inflation|
|Calculation||Does not adjust for inflation||Adjusted for inflation|
|Price Changes||Includes the impact of price changes||Removes the impact of price changes|
|Inflation Effects||Reflects both changes in output and changes in prices||Reflects changes in output only|
|Economic Performance||Can be influenced by changes in prices||Provides a more accurate measure of economic growth|
|Comparability||Not suitable for comparing GDP across different time periods||Suitable for comparing GDP across different time periods|
|Income Distribution||Does not consider changes in purchasing power||Reflects changes in purchasing power|
