For instance, if prices in an economy have risen by 1% since the base year, the deflated number is 1.01. If nominal GDP is $1 million, real GDP equals $1,000,000 divided by 1.01, or $990,099.
How is the GDP deflator calculated using the base year?
The GDP deflator (implicit price deflator for GDP) is a measure of the level of prices in an economy for all new, domestically produced final goods and services. It is a price index that is calculated using nominal GDP and real GDP to measure price inflation or deflation.
Nominal GDP versus Real GDP
The market worth of all final commodities produced in a geographical location, generally a country, is known as nominal GDP, or unadjusted GDP. The market value is determined by the quantity and price of goods and services produced. As a result, if prices move from one period to the next but actual output does not, nominal GDP will vary as well, despite the fact that output remains constant.
Real gross domestic product, on the other hand, compensates for price increases that may have happened as a result of inflation. To put it another way, real GDP equals nominal GDP multiplied by inflation. Real GDP would remain unchanged if prices did not change from one period to the next but actual output did. Changes in real production are reflected in real GDP. Nominal GDP and real GDP will be the same if there is no inflation or deflation.
What is the formula for real GDP?
The percentage change in real GDP per capita between two consecutive years is used to compute the annual growth rate of real GDP per capita. GDP at constant prices is divided by the population of a country or area to get real GDP per capita. To make calculating country growth rates and aggregating country data easier, real GDP data are measured in constant US dollars.
Why is GDP calculated using the base year?
The Gross Domestic Product, or GDP, is a metric that is commonly used to assess a country’s economic development.
GDP can be calculated in one of two ways: by adding up what everyone made in a year (income approach) or by adding up what everyone spent in a year (spend approach) (expenditure method). Both measures should, in theory, yield nearly the same total. The income approach, often known as GDP (I), is determined by summing total employee remuneration, gross earnings for incorporated and unincorporated businesses, and taxes, minus any subsidies. The expenditure technique is more commonly used, and it involves adding total consumption, investment, government spending, and net exports together.
The Central Statistical Organisation of India determines the country’s gross domestic product (GDP) (GDP). The GDP of India is estimated using two methods: one based on economic activity (at factor cost) and the other based on expenditure (at market prices). The performance of eight distinct industries is evaluated using the factor cost technique. The approach for calculating GDP estimates is to divide the entire economy into distinct sectors, which include primary, secondary, and tertiary activity. The production approach is used to estimate GDP in agriculture, forestry and logging, fishing, mining and quarrying, registered manufacturing (establishments registered under the Factories Act, 1948), and building. Unregistered manufacturing (establishments not registered under the Factories Act), trade, hotels and restaurants, transportation, storage, communication, banking and insurance, real estate, ownership of dwellings, business services, public administration and defense, and other services all use the income approach to estimate GDP. Estimates for various public services are compiled by analyzing budget documents and annual reports of departmental and non-departmental commercial undertakings; estimates for the organized (registered) manufacturing sector are based on data from the Annual Survey of Industries; and estimates for the unorganized sectors in various economic activities are based on per worker value added figures obtained from the results of follow-up surveys.
In general, the estimate of GDP for unorganized sectors is gathered for the base year or benchmark survey year, and estimates for succeeding years are generated by shifting the base year estimate using suitable physical indicators (www.mospi.gov.in/133-gross-domestic-product).
In order to understand development in real terms, a specific year is used as the Base Year when computing GDP. If GDP is measured based on current year’s prices, actual growth cannot be assessed due to price increases.
In India, a new series was announced in 2015 to calculate GDP by upgrading the methodology with new data sources to meet UN standards, and since then, there have been questions about the measure’s suitability and accuracy, with 2011-12 as the base-year, replacing the previous series with the base-year 2004-05. It contained information on all companies registered with the Ministry of Corporate Affairs, and each company was assigned a unique 21-digit code, hence the MCA-21 designation. But we’re all aware of a huge issue, which I’m bringing up again. According to a news article from May 2019, roughly 38% of enterprises polled by the NSSO from the MCA-21 database of companies used to calculate GDP could not be traced or were incorrectly categorised.
According to different media, the Central Statistics Office (CSO) plans to replace the 2011-12 GDP series with a new set of National Accounts using 2017-18 as the base year in the coming months.
At this point, I’d want to point out that the positive or negative impacts of anticipation cannot be assessed. Only after it has been implemented can a proposition and its ramifications be assessed. It’s worth noting that the base year was changed from 2004-05 to 2011-12, implying a 6-7-year gap, with the same period now being considered (the base year 2017-18). Only time will tell whether the base year has positive or negative impacts, but defects should not exist (as I have mentioned one flaw).
Without real GDP, how can you calculate GDP deflator?
We can calculate the actual GDP deflator now that we know both nominal and real GDP. To do so, multiply the result by 100 and divide nominal GDP by real GDP. This gives us the change in nominal GDP that cannot be attributable to changes in real GDP (from the base year). Take a look at the formula below:
Returning to our example, we can observe that the 2015 GDP deflator is 100 (*100). Because nominal and real GDP must be equal, the GDP deflator for the base year will always be 100. When we move ahead a few years, however, things start to get more intriguing. The GDP deflator for the year 2016 is 7 160.9 (*100). That is, the price level increased by 60.9 percent (160.9 100) from 2015 to 2016. Similarly, the GDP deflator for 2017 is 243.4, reflecting a 143.4 percent increase in price levels over the base year.
What are instances of real GDP and nominal GDP?
Real GDP is GDP that has been adjusted for price fluctuations. Nominal GDP is GDP that hasn’t been adjusted for price fluctuations. If real GDP is $1,000 in Year 1 and $1,028 in Year 2, the production growth rate from Year 1 to Year 2 is 2.8 percent; (1,028-1,000)/1,000 =
How are nominal GDP and real GDP price index calculated?
Multiplying by 100 produces a beautiful round value, which is useful for reporting. To calculate real GDP, however, the nominal GDP is divided by the price index multiplied by 100.
The price index is set at 100 for the base year to make comparisons easier. Prices were often lower prior to the base year, so those GDP estimates had to be inflated to compare to the base year. When prices are lower in a given year than they were in the base year, the price index falls below 100, causing real GDP to exceed nominal GDP when computed by dividing nominal GDP by the price index. For the base year, real GDP equals nominal GDP.
Another way to calculate real GDP is to count the volume of output and then multiply that volume by the base year’s prices. So, if a gallon of gas cost $2 in 2000 and the US produced 10,000,000,000 gallons, these figures can be compared to those of a subsequent year. For example, if the United States produced 15,000,000,000 gallons of gasoline in 2010, the real increase in GDP due to gasoline might be estimated by multiplying the 15 billion by the $2 per gallon price in 2000. After that, divide the nominal GDP by the real GDP to get the price index. For example, if gasoline cost $3 a gallon in 2010, the price index would be 3 / 2 100 =150.
Of course, both methods have their own set of complications when it comes to estimating real GDP. Statisticians are forced to make assumptions about the proportion of each sort of commodity and service purchased over the course of a year.

How do you determine the base year?
A base year is used for comparison when determining a commercial operation or economic indicator. The base year, or the first year in the chosen period, is, for example, determining the inflation rate between 2013 and 2018. The base year can also serve as a beginning point for calculating same-store sales by serving as a growth point or a benchmark.
Many financial ratios are based on growth because investors want to know how much a given figure changes over time. (Current year – Base year) / Base year is the growth rate calculation. In ratio analysis, the base period is the past.
Growth analysis is a frequent approach of describing a company’s success, particularly in sales. For instance, if a company’s income increases from Rs.50,000 to Rs.60,000, it has raised revenues by 20%, with Rs.50,000 as the base year.
How can you figure out the difference in real GDP between two years?
What proportion of the growth in GDP is due to inflation and what proportion is due to an increase in actual output? To answer this topic, we must first examine how economists compute Real Gross Domestic Product (RGDP) and how it differs from Nominal GDP (NGDP). The market value of output and, as a result, GDP might rise due to increased production of products and services (quantities) or higher prices for commodities and services. Because the goal of assessing GDP is to see if a country’s ability to generate larger quantities of goods and services has changed, we strive to exclude the effect of price fluctuations by using prices from a reference year, also known as a base year, when calculating RGDP. When calculating RGDP, we maintain prices fixed (unchanged) at the level they were in the base year. (1)
Calculating Real GDP
- The value of the final products and services produced in a given year represented in terms of prices in that same year is known as nominal GDP.
- We use current year prices and multiply them by current year quantities for all the goods and services generated in an economy to compute nominal GDP. We’ll use hypothetical economies with no more than two or three goods and services to demonstrate the method. You can imagine that if a lot more items and services were included, the same principle would apply.
- Real GDP allows for comparisons of output volumes throughout time. The value of final products and services produced in a given year expressed in terms of prices in a base year is referred to as real GDP.
- For all the products and services produced in an economy, we utilize base year prices and multiply them by current year amounts to calculate Real GDP. We’ll use hypothetical economies with no more than two or three goods and services to demonstrate the method. You can imagine that if a lot more items and services were included, the same principle would apply.
- Because RGDP is calculated using current-year prices in the base year (base year = current-year), RGDP always equals NGDP in the base year. (1)
Example:
Table 3 summarizes the overall production and corresponding pricing (which you can think of as average prices) of all the final goods and services produced by a hypothetical economy in 2015 and 2016. The starting point is the year 2015.
Year 2016
Although nominal GDP has expanded tremendously, how has real GDP changed throughout the years? To compute RGDP, we must first determine which year will serve as the base year. Use 2015 as the starting point. Then, in 2015, real GDP equals nominal GDP equals $12,500 (as is always the case for the base year).
Because 2015 is the base year, we must use 2016 quantities and 2015 prices to calculate real GDP in 2016.
From 2015 to 2016, RGDP increased at a slower rate than NGDP. If both prices and quantity rise year after year, this will always be the case. (1)
