The total unduplicated value of products and services produced in a country’s or region’s economic territory over a certain period is known as gross domestic product (GDP).
GDP can be calculated in three different ways. There are three approaches: production, revenue, and expenditure.
To calculate value added, subtract an industry’s or sector’s output from its intermediate consumption (the commodities and services utilized to make the output). The gross value added of all industries or sectors for a certain province or territory is combined together to get total GDP for the economic territory. The GDP at market prices is calculated by adding all taxes and product subsidies to the total value added for all industries.
For example, if the automotive industry’s total output was $10 billion in cars and $6 billion in material inputs (steel, plastic, electricity, business services, etc.) were used to make the cars, the value added for the industry would be $10 billion in output minus $6 billion in intermediate consumption, or $4 billion.
Using the production approach to quantify GDP, the following tables show estimates of gross domestic product by province and territory by industry.
What is the formula for calculating GDP?
GDP is thus defined as GDP = Consumption + Investment + Government Spending + Net Exports, or GDP = C + I + G + NX, where consumption (C) refers to private-consumption expenditures by households and nonprofit organizations, investment (I) refers to business expenditures, and net exports (NX) refers to net exports.
What are the three methods for calculating GDP?
There are three major ways for calculating GDP. When computed correctly, all three methods should produce the same result. The expenditure method, the output (or production) approach, and the income approach are the three approaches that are commonly used.
How is GDP measured using the income approach?
- All economic expenditures should equal the entire revenue created by the production of all economic products and services, according to the income approach to computing gross domestic product (GDP).
- The expenditure technique, which starts with money spent on goods and services, is an alternative way for computing GDP.
- The national income and product accounts (NIPA) are the foundation for calculating GDP and analyzing the effects of variables such as monetary and fiscal policies.
