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.
How do you figure out the real GDP growth rate?
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.
For example, how do you compute real GDP per capita?
The formula for calculating per capita is: measurement per capita = measurement / population. GDP per capita, for example, equals GDP divided by population.
Write out the formula
The average growth rate over time formula must first be written down. The formula will serve as a starting point for your calculations. You’ll need the numbers for each year and the number of years you’re comparing for the average growth rate over time formula. The average growth rate over time approach is calculated by dividing the current number by the previous value, multiplying to the 1/N power, and then subtracting one. The number of years is represented by “N” in this formula.
In Excel, how do you compute real GDP per capita?
Consider a country with a $10 trillion real GDP in 2018 and a population of 250 million people as of December 31, 2018. Calculate the country’s GDP per capita for the year 2018.
As a result, the country’s GDP per capita for the year 2018 was $40,000.
GDP Per Capita Formula Example #2
Take, for example, a country that has the following data for the year 2018. Calculate the country’s GDP per capita using the information provided.
Why does the real GDP growth rate differ from the real GDP per capita growth rate?
The average level of national income (adjusted for inflation) per person is measured as real GDP per capita. It provides an approximate idea of normal living conditions.
- GDP (Gross Domestic Product) is a measure of an economy’s national output/national income; it is a volume measure of goods and services generated in a given year.
- Inflation is factored into real GDP. To put it another way, Real GDP accounts for the actual increase in goods and services while excluding the impact of growing prices.
- The average GDP per person in the economy is included into real GDP per capita.
Importance of GDP per capita
- Between 2005 and 2015, this graph depicts the difference in real GDP and real GDP per capita in the United Kingdom.
- The increase in per capita GDP is much lower than standard real GDP due to population growth.
- As a result, while real GDP increased, average earnings did not. See also: per capita economic growth.
Comparisons of GDP per capita around the world
Purchasing power parity is used to calculate real GDP per capita (it takes into account local cost of living). Even when measured in terms of purchasing power parity, there remains a significant disparity between prosperous countries like Norway and impoverished countries like Ghana.
What effect does population growth have on GDP per capita growth?
Economic and Population Growth: What’s the Connection? Higher population growth rates would definitely lead to higher economic growth rates if population growth and per capita GDP growth are fully independent.
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.

With price and quantity, how do you calculate real GDP?
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)
