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.
What is the nominal GDP formula?
C + I + G + (X M) = GDP The value of items is taken at current year’s prices to compute nominal GDP, which is done using the consumer price index of the basket of goods.
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.
Is nominal GDP and real GDP the same thing?
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.
In economics, what is nominal GDP?
The nominal GDP of a country is calculated using current prices and is not adjusted for inflation. Compare this to real GDP, which accounts for the impact of inflation on a country’s economic output. While both indices measure the same output, they are employed for quite different purposes: value changes versus volume changes.
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.
Expenditure Approach
The most widely used GDP model is the expenditure approach, which is based on the money spent by various economic participants.
C = consumption, or all private consumer spending in a country’s economy, which includes durable goods (things having a lifespan of more than three years), non-durable products (food and clothing), and services.
G stands for total government spending, which includes salaries, road construction/repair, public schools, and military spending.
I = the total amount of money spent on capital equipment, inventory, and housing by a country.
Income Approach
The total money earned by the goods and services produced is taken into account in this GDP formula.
Total National Income + Sales Taxes + Depreciation + Net Foreign Factor Income = Gross Domestic Product
What was the nominal GDP of the economy in the first year?
Assume that in year one of a three-good economy, annual output is 3 quarts of ice cream, 1 bottle of shampoo, and 3 jars of peanut butter. The production mix shifts to 5 quarts of ice cream, 2 bottles of shampoo, and 2 jars of peanut butter in year two.
What was the economy’s nominal GDP in the first year if ice cream was $4 per quart, shampoo was $3 per bottle, and peanut butter was $2 per jar?
Year 1: 3 quarts of ice cream, 1 bottle of shampoo, and 3 jars of peanut butter are the outputs.
In year two, the output combination is changed to 5 quarts of ice cream, 2 shampoo bottles, and 2 jars of peanut butter.
Ice cream is $4 per quart, shampoo is $3 per bottle, and peanut butter is $2 per jar in both years.
Remember that GDP is the most basic indicator of an economy’s health. Price movements are not taken into account while calculating nominal GDP (also known as currentdollar economic data). You must use the formula Nominal GDP= P*Q to calculate nominal GDP (the value of all final products and services valued at current-year prices).
Economists prefer to use real GDP to get a true picture of a country’s economic growth. You must apply the formula Real GDP= P*Q to calculate real GDP (the value of all final goods and services valued at base-year prices for each year).
In this scenario, you’ll need to take a few actions. The first step is to figure out how much each item costs. The second step is to tally up the nominal worth of each year’s commodities separately.
- Assume that the output mix changes again in year three, to 3 quarts of ice cream, 1 bottle of shampoo, and 3 jars of peanut butter. Consider the first year to be the starting point.
2.1. What is the economy’s real GDP in year 3 if the price of a quart of ice cream is $5, a bottle of shampoo is $4, and a jar of peanut butter is $3?
In years 1 and 2, compute nominal GDP, real GDP, and the GDP price index. Fill in the blanks in the accompanying table and exhibit your work.
The base year is the year in which the index is equal to 100.
To compute the GDP price index, multiply the price of a group of goods and services in a given year (year 2 or year 3) by the price of the same goods and services in a base year (year 1) multiplied by 100. To calculate real GDP, divide nominal GDP by the price index (in hundredths).
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 nominal real GDP and CPI 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.

What is the distinction between nominal and real GDP?
The annual production of goods or services at current prices is measured by nominal GDP. Real GDP is a metric that estimates the annual production of goods and services at their current prices, without the impact of inflation. As a result, nominal GDP is considered to be a more appropriate measure of GDP.
If you are a business owner or a customer, you should understand the difference between a nominal and actual gross domestic product. These notions are crucial because they will help you make vital purchasing and selling decisions.
