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 real GDP calculated using nominal GDP and a price index?
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.

What is the difference between nominal and real GDP?
The total value of all products and services produced in a specific time period, usually quarterly or annually, is referred to as nominal GDP. Nominal GDP is adjusted for inflation to produce real GDP. Real GDP is a measure of actual output growth that is free of inflationary distortions.
What is economics of real GDP?
The inflation-adjusted value of goods and services produced by labor and property in the United States is known as real gross domestic product.
What is the formula for calculating nominal GDP for two goods?
GDP is the total monetary worth of all products and services produced in a given economy over a given time period (usually a year).
There are nominal and real prices (or values – but continue with the term “prices” because it is clearer).
The present nominal prices, that is, the prices for the current year, are referred to as nominal prices. Nominal prices, on the other hand, are based on the current year’s pricing. Real prices are calculated using prices from a single year, which can be chosen purposefully with (usually) no issues for the analysis.
It is not a good idea to utilize nominal prices since they exaggerate GDP, as prices in an economy fluctuate from one period to the next (generalized and continuous increase in prices). Real pricing do not include this because they are based on prices from a given year. To compute real GDP, for example, you’ll need the GDP deflator (which is rather simple to calculate and can be found in databanks such as the World Bank and the IMF).
Now that definitions have been properly acknowledged, you can calculate nominal GDP in a basic model with two goods/services by multiplying the price of the good by its quantity.
What method do you use to compute actual GDP? You select a base year and multiply each year’s quantities by the prices from that year. I could go on, but let me finish with a question: what is the GDP for those years in 2014 dollars?
As can be seen, the real GDP incorporates the drop in burger production and the “stagnation” of fries production in 2014, and measures the increase in GDP in 2015 without exaggeration.
Last but not least, it’s worth noting that real GDP equals nominal GDP in your base year.
What is the formula for GDP?
Gross domestic product (GDP) equals private consumption + gross private investment + government investment + government spending + (exports Minus imports).
GDP is usually computed using international standards by the country’s official statistical agency. GDP is calculated in the United States by the Bureau of Economic Analysis, which is part of the Commerce Department. The System of National Accounts, compiled in 1993 by the International Monetary Fund (IMF), the European Commission, and the Organization for Economic Cooperation and Development (OECD), is the international standard for estimating GDP.
How do you figure out actual GDP?
To calculate Real GNP, first compute nominal GNP by adding foreign earnings capital gains to GDP, then factor in inflation by dividing the total by the Consumer Price Index and multiplying by 100.
How are real GDP and economic growth calculated?
The real GDP growth rate illustrates how much a country’s real GDP has changed over time, usually from one year to the next. It’s computed by first calculating real GDP for two consecutive periods, then calculating the change in GDP between the two periods, dividing the change in GDP by the beginning GDP, then multiplying the result by 100 to produce a percentage.
What is a nominal GDP example?
The GDP Deflator method necessitates knowledge of the real GDP level (output level) as well as the price change (GDP Deflator). The nominal GDP is calculated by multiplying both elements.
GDP Deflator: An In-depth Explanation
The GDP Deflator measures how much a country’s economy has changed in price over time. It will start with a year in which nominal GDP equals real GDP and multiply it by 100. Any change in price will be reflected in nominal GDP, causing the GDP Deflator to alter.
For example, if the GDP Deflator is 112 in the year after the base year, it means that the average price of output increased by 12%.
Assume a country produces only one type of good and follows the yearly timetable below in terms of both quantity and price.
The current year’s quantity output is multiplied by the current market price to get nominal GDP. The nominal GDP in Year 1 is $1000 (100 x $10), and the nominal GDP in Year 5 is $2250 (150 x $15) in the example above.
According to the data above, GDP may have increased between Year 1 and Year 5 due to price changes (prevailing inflation) or increased quantity output. To determine the core cause of the GDP increase, more research is required.
Key Points
- The GDP deflator is a price inflation indicator. It’s computed by multiplying Nominal GDP by Real GDP and then dividing by 100. (This is based on the formula.)
- The market value of goods and services produced in an economy, unadjusted for inflation, is known as nominal GDP. To reflect changes in real output, real GDP is nominal GDP corrected for inflation.
- The GDP deflator’s trends are similar to the Consumer Price Index, which is a different technique of calculating inflation.
Key Terms
- GDP deflator: A measure of the level of prices in an economy for all new, domestically produced final products and services. The ratio of nominal GDP to the real measure of GDP is used to compute it.
- A macroeconomic measure of the worth of an economy’s output adjusted for price fluctuations is known as real GDP (inflation or deflation).
- Nominal GDP is a non-inflationary macroeconomic measure of the value of an economy’s output.
