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 calculate real GDP growth?
In general, real GDP is calculated by multiplying nominal GDP by the GDP deflator (R). 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 GDP real growth rate?
Retail and wholesale trade industries led the increase in private inventory investment. The largest contributor to retail was inventory investment by automobile dealers. Increases in both products and services contributed to the increase in exports. Consumer products, industrial supplies and materials, and foods, feeds, and beverages were the biggest contributions to the growth in goods exports. Travel was the driving force behind the increase in service exports. The rise in PCE was mostly due to an increase in services, with health care, recreation, and transportation accounting for the majority of the increase. The increase in nonresidential fixed investment was mostly due to a rise in intellectual property items, which was partially offset by a drop in structures.
The reduction in federal spending was mostly due to lower defense spending on intermediate goods and services. State and local government spending fell as a result of lower consumption (driven by state and local government employee remuneration, particularly education) and gross investment (led by new educational structures). The rise in imports was mostly due to a rise in goods (led by non-food and non-automotive consumer goods, as well as capital goods).
After gaining 2.3 percent in the third quarter, real GDP increased by 6.9% in the fourth quarter. The fourth-quarter increase in real GDP was primarily due to an increase in exports, as well as increases in private inventory investment and PCE, as well as smaller decreases in residential fixed investment and federal government spending, which were partially offset by a decrease in state and local government spending. Imports have increased.
In the fourth quarter, current dollar GDP climbed 14.3% on an annual basis, or $790.1 billion, to $23.99 trillion. GDP climbed by 8.4%, or $461.3 billion, in the third quarter (table 1 and table 3).
In the fourth quarter, the price index for gross domestic purchases climbed 6.9%, compared to 5.6 percent in the third quarter (table 4). The PCE price index climbed by 6.5 percent, compared to a 5.3 percent gain in the previous quarter. The PCE price index grew 4.9 percent excluding food and energy expenses, compared to 4.6 percent overall.
Personal Income
In the fourth quarter, current-dollar personal income climbed by $106.3 billion, compared to $127.9 billion in the third quarter. Increases in compensation (driven by private earnings and salaries), personal income receipts on assets, and rental income partially offset a decline in personal current transfer receipts (particularly, government social assistance) (table 8). Following the end of pandemic-related unemployment programs, the fall in government social benefits was more than offset by a decrease in unemployment insurance.
In the fourth quarter, disposable personal income grew $14.1 billion, or 0.3 percent, compared to $36.7 billion, or 0.8 percent, in the third quarter. Real disposable personal income fell 5.8%, compared to a 4.3 percent drop in the previous quarter.
In the fourth quarter, personal savings totaled $1.34 trillion, compared to $1.72 trillion in the third quarter. In the fourth quarter, the personal saving rate (savings as a percentage of disposable personal income) was 7.4 percent, down from 9.5 percent in the third quarter.
GDP for 2021
In 2021, real GDP climbed 5.7 percent (from the 2020 annual level to the 2021 annual level), compared to a 3.4 percent fall in 2020. (table 1). In 2021, all major subcomponents of real GDP increased, led by PCE, nonresidential fixed investment, exports, residential fixed investment, and private inventory investment. Imports have risen (table 2).
PCE increased as both products and services increased in value. “Other” nondurable items (including games and toys as well as medications), apparel and footwear, and recreational goods and automobiles were the major contributors within goods. Food services and accommodations, as well as health care, were the most significant contributors to services. Increases in equipment (dominated by information processing equipment) and intellectual property items (driven by software as well as research and development) partially offset a reduction in structures in nonresidential fixed investment (widespread across most categories). The rise in exports was due to an increase in products (mostly non-automotive capital goods), which was somewhat offset by a drop in services (led by travel as well as royalties and license fees). The increase in residential fixed investment was primarily due to the development of new single-family homes. An increase in wholesale commerce led to an increase in private inventory investment (mainly in durable goods industries).
In 2021, current-dollar GDP expanded by 10.0 percent, or $2.10 trillion, to $22.99 trillion, compared to 2.2 percent, or $478.9 billion, in 2020. (tables 1 and 3).
In 2021, the price index for gross domestic purchases climbed by 3.9 percent, compared to 1.2 percent in 2020. (table 4). Similarly, the PCE price index grew 3.9 percent, compared to 1.2 percent in the previous quarter. The PCE price index climbed 3.3 percent excluding food and energy expenses, compared to 1.4 percent overall.
Real GDP rose 5.5 percent from the fourth quarter of 2020 to the fourth quarter of 2021 (table 6), compared to a 2.3 percent fall from the fourth quarter of 2019 to the fourth quarter of 2020.
From the fourth quarter of 2020 to the fourth quarter of 2021, the price index for gross domestic purchases grew 5.5 percent, compared to 1.4 percent from the fourth quarter of 2019 to the fourth quarter of 2020. The PCE price index climbed by 5.5 percent, compared to 1.2 percent for the year. The PCE price index increased 4.6 percent excluding food and energy, compared to 1.4 percent overall.

In Excel, how do you compute GDP growth rate?
Actually, the XIRR function in Excel may be used to quickly calculate the Compound Annual Growth Rate, but it needs you to construct a new table with the start and end values.
1. Create a new table with the following start and end values as shown in the first screen shot:
Note: You can put =C3 in Cell F3, =B3 in Cell G3, =-C12 in Cell F4, and =B12 in Cell G4, or you can simply enter your original data into this table. By the way, the End Value must be preceded by a minus.
2. Select a blank cell beneath this table, type the formula below into it, then hit Enter.
3. To convert the result to % format, select the Cell with the XIRR function, go to the Home tab, click the Percent Style button, and then modify the decimal places using the Increase Decimal button or Decrease Decimal button. Take a look at this screenshot:
In economics, what is the growth rate?
An economic growth rate is the percentage change in the value of all products and services produced in a country over a given time period when compared to a previous period. The economic growth rate is used to assess an economy’s relative health across time.
How fast am I growing?
How Do You Calculate a Population’s Growth Rate? A population’s growth rate can be calculated by subtracting the prior population size from the current population size, just like any other growth rate calculation. Subtract the previous size from the total. To get the percentage, multiply that by 100.
How is real GDP calculated using price and quantity?
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)
What is the formula for calculating real GDP per capita?
The formula for calculating a country’s total economic output per person after adjusting for inflation is known as the Real GDP Per Capita Formula. Real GDP per capita is computed by dividing the country’s real GDP (total economic output adjusted for inflation) by the total number of people in the country, according to the formula.
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.
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.
