Gross Domestic Product (GDP) stands out as a key factor in calculating a finished product's total monetary (money) value. In this article, we'll explain the concept of GDP, take a look into its formula, and focus on how to correctly use it for accurate analysis. Knowing everything about GDP helps businesses make informed decisions and keep up with the changing financial trends.
Let’s understand the importance of GDP, its limits, its key role as an information source for main decision-makers in different industries.
What Is Gross Domestic Product (GDP)?
Gross Domestic Product (GDP) represents the total value of all completed goods and services produced within the country over a specific timeframe. In addition to providing an overview of a country's overall domestic output, it acts as a complete report, showing the country's economic well-being.
Usually calculated annually, GDP is sometimes calculated quarterly as well. As a result, the figures in this report are presented in real terms, meaning they are adjusted for price changes, providing a net value that accounts for price change effects.
Understanding Gross Domestic Product (GDP)
A nation's Gross Domestic Product (GDP) includes a wide mix of factors, including private and public expenses, government expenses, investments, additions to private inventories, paid-in construction costs, and the foreign trade balance. In addition, exports contribute positively to the GDP value, while imports reduce it.
Foreign trade balance is very important among the various factors shaping a country's GDP. A country's GDP rises when the total value of goods and services sold by domestic producers to foreign countries is more than the value of foreign goods and services purchased by domestic customers. This scenario is commonly known as a trade surplus (gain).
On the other hand, if domestic buyers spend more on foreign products than domestic producers can sell to foreign buyers, it causes a trade deficit (shortage). In such instances, the GDP of a country tends to decrease.
GDP can be calculated using either a nominal or a real basis, the real basis accounting for price changes. Real GDP, expressed in real (constant) rupees, offers the best measure for tracking long-term national growth.
Here is a gross domestic product example:
- Imagine a country that had a total income of Rs. 7.5 lakh crore in the year 2012.
- Fast forward to 2022, and this income grew to Rs. 11.25 lakh crore.
At first glance, the country's economy is doing well. However, during this period, prices across the nation also increased by 100%, that is, inflation.
Now, if we only consider the total income (nominal GDP), the country is doing well. But when we factor in rising prices, the real income value is much less.
Let's understand this in simpler terms. Think of the total income as the money your family earns.
- In 2012, it was Rs. 7.5 lakh per year.
- If you jump to 2022, your family seems to make Rs. 11.25 lakh per year.
Great, right? But hold on, because prices of things you buy - like groceries, clothes, and other necessary items - also doubled during this time.
So, when we convert the 2022 income into the equivalent of 2012 rupees (real GDP), it's only Rs. 7.5 lakh. This means that even though it looks like your family is earning more when you consider the increased prices, the actual purchasing power has not grown. In fact, it might have decreased.
This is similar to what happens in a country's economy. Just looking at the total income (nominal GDP) doesn't give the full picture. We need to adjust for price changes to see if the country is truly better off. If, after accounting for inflation, the real GDP is less than the nominal GDP, the country's actual economic performance has not improved as much as it might seem.
Types of Gross Domestic Product
Gross Domestic Product (GDP) is measured in various ways. Each has a unique viewpoint on a nation's economic activity. Here, we understand the various types of GDP:
1. Nominal GDP
Nominal GDP represents the total value of all goods and services produced within a country's borders, measured at current market prices. It provides a simple picture of economic output without considering inflation (price changes).
2. Real GDP
Real GDP, on the other hand, takes inflation or deflation into account. By expressing the value of goods and services in real (constant) rupees, real GDP correctly represents changes in a nation's actual economic output over time.
3. GDP Per Capita
Gross Domestic Product per capita divides the total GDP of a country by its population, providing a per-person measure of economic performance. This method allows for comparisons of the standard of living between different countries.
4. Gross National Product (GNP)
GNP includes the total value of all goods and services produced by a country's citizens, both domestically and abroad, minus the value created by foreign residents within the country's borders. It provides a detailed view of a nation's economic output, including income generated abroad.
5. Gross National Income (GNI)
GNI calculates GNP by including payments received from abroad and subtracting payments made to foreign organizations. This method offers a more complete measure of a country's economic well-being.
GDP Formula
The most common gross domestic product formula is the expenditure approach, which is calculated as:
[GDP = C + G + I + (N- X)]
Where: “C” is household consumption expenditure, “G” is government spending, “I” is gross private domestic investment, “NX” is exports and imports of goods and services.
GDP can also be calculated using the income approach, which sums up all the incomes earned in producing goods and services. The formula for income approach is:
GDP= Compensation of Employees + Gross Profit + Gross Rental and Royalty Income + Taxes on Production and Imports − Subsidies.
Another approach is the production or output approach. In this, we calculate the value of all goods and services produced within a country during a specific period. The formula for GDP using the production approach is:
GDP= Value of Output − Value of Intermediate Consumption.
In this formula: Value of Output is the total value of goods and services produced by all industries within a country. Value of Intermediate Consumption is the value of goods and services used in the production process. It includes raw materials, intermediate goods, and services used to produce final goods and services.
Adjustments to GDP
Gross Domestic Product (GDP) is an important measure of a nation's wealth, but its use in measuring the standard of living is limited. Variations in population size and cost of living across countries prevent direct GDP comparisons. To solve this, economists often turn to gross domestic product per capita, calculated by dividing total GDP by the population. However, this measurement is imperfect because it doesn’t take into account the differences in the cost of living.
For instance, comparing India’s nominal GDP to the USA's without considering their vast population difference gives little idea of the living conditions. To make better comparisons, economists use Purchasing Power Parity (PPP), adjusting for exchange rates to measure how much a unit of money can buy in different countries. Real per-capita GDP, adjusted for PPP, provides a more accurate measure of true income, which is important for measuring well-being. This approach includes nominal income and relative living costs, offering a more detailed understanding of economic growth per person.
How to Use GDP Data
Countries regularly publish GDP data on a monthly and quarterly basis. Although GDP data is not current and has a limited effect on markets because of the delay between the quarter-end and the release, major variations from forecasts can still affect the market.
Despite its non-current nature, GDP is a key indicator of economic health and growth. Businesses can use GDP data to shape their strategies, while government agencies use GDP growth rates and related research to make financial decisions.
Real GDP is closely checked regularly by economists, analysts, investors, and policymakers. The release of the latest data typically affects markets but with a sometimes limited impact, highlighting its importance in shaping and impacting economic decisions.
GDP and Investing
Investors closely monitor GDP as it offers valuable data for decision-making. Comparing GDP growth rates across countries is important in financial management decisions.
Corporate profits and inventory data within the GDP report are handy for equity investors, providing a complete view of total growth during the period. Corporate profits data further breaks down pre-tax profits, net cash flows, and sector-specific information.
Investors decide whether to invest in quickly growing foreign economies and, if so, which presents the most promising opportunities.
History of GDP
The concept of Gross Domestic Product (GDP) goes back to 1937 when economist Simon Kuznets introduced the concept in reaction to the Great Depression as part of a report to the U.S. Congress. Even though the traditional use of Gross National Product (GNP) as the primary measurement system, GDP gained popularity after the Bretton Woods conference in 1944. However, the United States used GNP as its official measure of economic welfare until 1991, when it officially shifted to GDP.
By the 1950s, doubts about GDP grew among economists and policymakers. Critics highlighted its limitation in providing key indicators of national well-being, such as health, happiness, and inequality. While some argued that GDP served as an absolute indicator of economic success, with every increase leading to a drop in unemployment, others, like Arthur Okun, acknowledged a difference between economic progress and broader social progress. This ongoing debate has shaped the discussion on the limitations and usefulness of GDP as an overall measure of a nation's success.
Global Sources for Country GDP Data
There are various sources which you can use to understand GDP of a nation.
- The World Bank stands out with its extensive web-based database for accurate country GDP data, offering detailed information on various countries.
- The International Monetary Fund (IMF) is another reputable source, presenting GDP data through various databases like World Economic Outlook and International Financial Statistics.
- The Organization for Economic Cooperation and Development (OECD) is a reliable option, offering historical GDP data and growth forecasts.
- The Fed database lacks real-time updates for GDP data and may not cover all countries, it remains a valuable resource.
- The Bureau of Economic Analysis (BEA), a U.S. Department of Commerce division, provides informative documents with each GDP release. These documents serve as valuable tools for investors, offering a detailed review of figures, trends, and highlights from the in-depth full release.
