Real GDP: Definition, Formula, And Example
Gross domestic product (or "GDP") is one of the most important, poorly understood parts of political debate.
This is what economists refer to when they talk about the size of an economy. It's what politicians refer to when they talk about economic growth. Depending on who you talk to, it's either the cornerstone of modern policy or a grossly overrated figure.
Here's what you need to know about real GDP.
What Is GDP?
Gross Domestic Product measures the total output of all the goods and services in an economy as measured by the price of those products. Typically GDP is expressed in U.S. Dollars, the world's standard reserve currency, however, economists can measure GDP in any currency they choose.
For example, take a sample economy with the following outputs:
If we assume that this represents the total of all work and production in our make-believe economy, it has the following GDP:
• ($10 x 20) + ($50 x 100) + ($25 x 10) + ($1,000 x 2) = $7,450
The total amount of goods, services, and work produced by this economy, otherwise known as its size, is $7,450.
Services
The gross domestic product also includes services and government-produced value. Service outputs are businesses that charge for time or labor rather than a per-unit product, such as lawyers, doctors, plumbers, electricians. The GDP typically (although not always) measures them based on revenue.
It also measures many forms of government work such as teaching or military services. This is typically calculated based on the salaries paid to those service providers given that they create value (protection and education create real, tangible benefits to consumers, for example) but don't directly charge consumers for that product. (Citizens pay for government services through taxes, but since not all tax dollars create value, it would be inaccurate to include the government's tax base in the GDP.)
Finished Products
Note that gross domestic product only measures final products sold to consumers. It does not include components or intermediate products. For example, in our study above, GDP would not measure the value of the lumber sold to the carpenter.
This is to avoid double-counting the same product.
What Is Real GDP?
Real GDP is a measure of gross domestic product that adjusts for inflation and deflation. This is as opposed to nominal GDP which measures gross domestic product based on unadjusted prices.
Inflation/Deflation
Inflation and deflation are the processes of prices changing on the same product from year to year either up or down respectively. For example, take a loaf of bread that costs $10 in 2019. If that same loaf of bread costs $11 in 2020 it has experienced inflation of 10%. If that bread, on the other hand, costs $9 in 2020 it has experienced deflation of 10%.
Deflation happens rarely in modern economies. Most experience annual rates of inflation, as prices go up due to increased access to cash and purchasing power by consumers.
Real GDP vs. Nominal GDP
Real GDP generally measures an economy's actual value more accurately than nominal GDP.
Nominal GDP measures the total output of an economy based only on prices. This means that the metric will increase both with economic output and also price inflation. For example, consider the bakery in our sample economy above. Under a measure of nominal GDP we might have two situations:
In both cases, the nominal GDP would grow by 10% (from $200 per year to $220). However in the second case that growth would be illusory. It wouldn't represent an economy generating more goods and services, just an economy charging more for the same ones.
By accounting for inflation or deflation, real GDP will only grow when an economy actually produces more and/or more valuable outputs. In our case above, for example, real GDP would show growth in the first situation but not in the second.
Using Nominal GDP
While real GDP measures an economy more accurately, economists use nominal GDP to measure an economy against factors that don't change with inflation. The most common example of this is debt. The national debt has an interest rate but it doesn't necessarily change with inflation. As a result, economists usually measure a nation's debt-to-GDP ratio based on nominal GDP.
How to Calculate Real GDP
Real GDP is calculated by the following formula: Real GDP = Nominal GDP / Deflator.
The deflator is a figure produced based on the rate of inflation. For example, say the national rate of inflation was 2% in a given year (indicating that the same goods and services cost an average of 2% more than they did the year before). In this case, the deflator will be 1.02.
For example, say an economy has a nominal GDP of $100 million, the raw total of all goods and services as measured by their prices. Assume also that the economy has experienced 2% inflation over the course of the year. We would calculate real GDP as:
After accounting for inflation, the economy actually produced approximately $98 million worth of goods and services.
How To Calculate The GDP Of A Country
How To Calculate The GDP Of A Country
The gross domestic product (GDP) of a nation is an estimate of the total value of all the goods and services it produced during a specific period, usually a quarter or a year. Its greatest use is as a point of comparison: Did the nation's economy grow or contract compared to the previous period measured?
Key Takeaways
There are two main ways to measure GDP: by measuring spending or by measuring income.
And then there's real GDP, which is an adjustment that removes the effects of inflation so that the economy's growth or contraction can be seen clearly.
Calculating GDP Based on Spending
One way of arriving at GDP is to count up all of the money spent by the different groups that participate in the economy. These include consumers, businesses, and government. All payments for goods and services that contribute to the GDP total.
In addition, some of the nation's goods and services are exported for sale overseas. And some of the products and services that are consumed are imports from abroad. The GDP calculation accounts for spending on both exports and imports.
Thus, a country’s GDP is the total of consumer spending (C) plus business investment (I) and government spending (G), plus net exports, which is total exports minus total imports (X-M).
Calculating GDP Based on Income
The flip side of spending is income. Thus, an estimate of GDP may reflect the total amount of income paid to everyone in the country.
This calculation includes all of the factors of production that make up an economy. It includes the wages paid to labor, the rent earned by land, the return on capital in the form of interest, and the entrepreneur’s profits. All of these make up the national income.
This approach is complicated by the need to make adjustments for some items that don't always appear in the raw numbers. These include:
In this income approach, the GDP of a country is calculated as its national income plus its indirect business taxes and depreciation, plus its net foreign factor income.
How To Calculate The GDP Of A Country Real GDP
Since GDP measures an economy’s output, it is subject to inflationary pressure. Over a period of time, prices typically go up, and this will be reflected in GDP.
A nation's unadjusted GDP can't tell you whether GDP went up because production and consumption increased or because prices went up.
Real GDP is a measure of an economy's output adjusted for inflation. The unadjusted figure is referred to as nominal GDP.
Real GDP adjusts nominal GDP so that it reflects the price levels that prevailed in a reference year, called“the "base year.”
How GDP Is Used
GDP is an important statistic that indicates whether an economy is growing or contracting. In the U.S., the government releases an annualized GDP estimate for every quarter and every year, followed by final figures for each of those periods.
Tracking GDP over time helps a government make decisions such as whether to stimulate the economy by pumping more cash into it or to cool it by pulling money out.
Businesses may use GDP as a factor when deciding whether to expand or contract production or whether to undertake major projects.
Investors watch GDP to get a sense of where the economy may be headed in the weeks ahead.
Drawbacks of GDP
While GDP is a useful way to get a sense of the state of an economy, it is by no means a perfect approach. One criticism is that it does not account for activities that are not part of the legalized economy. The proceeds of off-the-books labor, some cash transactions, drug dealing, and more are not factored into GDP.
Another criticism is that some activities that provide value are not factored into GDP. For instance, if you hire a maid to keep your house clean, a cook to prepare your meals, and a nanny to care for your children, you will pay these hired helpers and the payments will factor into GDP. If you do those jobs yourself, your contribution is not counted in GDP.
What is GDP (gross domestic product)- GDP definition and Types.
GDP:
The full form of GDP is Gross Domestic Product. The definition of GDP is as follows.
GDP is the monetary measure of the market values of all the goods and services produced in a specific period of time. It is usually calculated annually.
GDP is considered as the “most powerful statistical indicator of national development and progress” of a country. It is the world’s best yardstick of measuring the growth, economic status and living standards of the people of a country. It helps to compare the living standards between nations.
GDP Nominal: It is the GDP calculated using current market prices. Therefore, nominal GDP will include all of the changes in market prices that have occurred during the current year due to inflation or deflation.
History of GDP:
The basic concept of GDP was first introduced at the end of the 18th century. Simon Kuznets in 1934 an American economist, presented the modern concept of GDP. In 1944, at the Bretton Woods conference GDP was adopted as the main measure of a country's economy.
What is the GDP used for?
Some very important uses of GDP are as follows
1) GDP is the most commonly used measure of economic activity.
2) GDP is the world’s best yardstick of measuring the growth, economic status and living standards of the people of a country.
3) GDP helps to compare the living standards between nations.
4) GDP is a measure of the economic output of a country.
4) GDP is a measure of the economic output of a country.
Types of GDP:
There are three types of GDP
1) GDP (E): It is the GDP calculated using the Expenditure approach.
2) GDP (I): It is the GDP calculated using the Income approach.
3) GDP (P): It is the GDP calculated using the Production approach.
2) GDP (I): It is the GDP calculated using the Income approach.
3) GDP (P): It is the GDP calculated using the Production approach.
Note: Each type of GDP is calculated using different formulas, using respective parameters
Why we shouldn’t judge a country by its GDP?
GDP is very volatile and dynamic, it may change from constantly. GDP can change due to various factors. It does not portray the true living conditions, basic human needs like food, water, shelter, medication, and factors of wellbeing like education, IT, social liberty, equality, freedom of living, freedom of speech, happiness index, etc. of the population of a country.
So instead of GDP, the above-mentioned factors should be used as parameters to measure the growth of a country.
A good example of this is that during Barak Obama’s term US GDP never crossed 3%. So it doesn’t mean that during his term the USA did not progress and were unemployed and hungry. So Barak Obama is the only president on USA history to never have a year of 3% US GDP growth. But people of the US elected him for the second term even after the low GDP of the USA.
This fact is recently stated in a tweet by Donald Trump Jr. “Incredible numbers. I remember when “the experts” laughed about breaking 3%. Just because Obama never broke 2% doesn’t mean that someone with great policies can’t. Let’s keep this going”.
Some facts about the GDP of various counties of the world:
- Bangladesh has a GDP of 8.5 in 2019.
- Bangladesh has a GDP greater than that of India in 2019.
- Under PM. Naredar Modi India’s GDP declined from 9.0 in 2014 to 4.5% in 2019.
- USA has the highest GDP in 2019.
- Philippines has a GDP of 6.9.
- In India generally three states Karnataka, Tamil Nadu, and Maharashtra have more GDP than 20 other states of India.
- In the GDP of the US, state of Florida was the highest contributor in 2017 but in 2018 it was in fourth place with Columbia at the top. In 2019 it will again differ.
- so the social wellbeing parameters are better than the volatile GDP to calculate the development of a country.
Which country has the highest GDP in 2019?
Top Twenty counties with the highest GDP in 2019. GDP of US is the highest.
1) The United States of America 2) China 3) Japan 4) Germany 5) United Kingdom 6) France 7) India 8) Italy 9) Brazil 10) Canada 11) Russia 12) South Korea 13) Spain 14)Australia 15) Mexico 16) Indonesia 17) Netherland 18) Saudi Arabia 19) Turkey 20) Switzerland
