How to Calculate Real GDP
Gross domestic product (GDP) is a measure of the value of all goods and services produced within a country’s borders in a specific time period. It is often used as a measure of a country’s economic health.
Real GDP is a measure of GDP that has been adjusted for inflation. This means that real GDP reflects the actual changes in the volume of goods and services produced, rather than just changes in prices.
Calculating Real GDP
Real GDP is calculated by dividing nominal GDP by the GDP deflator. The GDP deflator is a measure of the overall price level of goods and services produced in an economy.
The formula for calculating real GDP is:
Real GDP = Nominal GDP / GDP DeflatorExample
Suppose that nominal GDP is $1,000,000 and the GDP deflator is 1.1.
To calculate real GDP, we would divide $1,000,000 by 1.1, which would give us a result of $909,090.
Uses of Real GDP
Real GDP is used by economists, policymakers, and businesses to measure economic growth and track the performance of an economy.

Other Measures of Economic Growth
In addition to real GDP, there are other measures of economic growth, such as:
- Gross national product (GNP)
- Net national income (NNI)
- Personal income
- Disposable personal income
FAQ
What is the difference between nominal GDP and real GDP?
