Real GDP Per Capita Formula

Formula to Calculate Real GDP Per Capita

Real GDP Per Capita Formula refers to the formula that is used in order to calculate the country’s total economic output with respect to per person after adjusting the effect of the inflation and as per the formula Real GDP Per Capita is calculated by dividing the real GDP of the country (country’s total economic output adjusted by inflation) by the total number of persons in the country.

The formula to calculate real GDP per capita is represented as below

Real GDP Per Capita  = Nominal GDP/(1+ Deflator)/Population

  • Nominal GDP/Deflator will be Real GDP
  • Deflator adjusts for inflation

Steps to Calculate Real GDP Per Capita

The calculation of real GDP per capita will be done by using the below steps:

  1. One needs to first calculate Nominal GDPNominal GDPNominal GDP (Gross Domestic Product) is the calculation of annual economic production of the entire country's population at current market prices of goods and services generated by four main sources: land appreciation, labour wages, capital investment interest, and entrepreneur profits calculated only on finished goods and more either by using income method, expenditure method or production method.

  2. Find out the deflator which shall be provided by the government of that economy

  3. Now divide the nominal GDP computed in step 1 by deflator gathered in step 2 to arrive at Real GDPReal GDPReal GDP can be described as an inflation-adjusted measure that reflects the value of services and goods produced in a single year by an economy, expressed in the prices of the base year, and is also known as "constant dollar GDP" or "inflation corrected GDP."read more.

  4. From statistical and census report one can find out the population of the country.

  5. The final step is to divide the Real GDP by the population which shall yield Real GDP per capita.

Example #1

Country MNS has a nominal GDP of $450 billion and the deflator rate is 25%. The population of the country MNS is 100 million. You are required to calculate real GDP per capita.


We are given all the desired inputs to calculate Real GDP per capita.

  • Nominal GDP: 450000000000
  • Deflator: 25%
  • Population: 100000000

Therefore, the calculation will be as follows,

Real GDP Per Capita Formula Example 1.1
  • = ($450,000,000,000 / (1 + 25%)/100,000,000
Real GDP Per Capita Formula Example 1.2

Example #2

MCX is a developed economyDeveloped EconomyA developed economy is the one that has a high per capita income or per capita GDP, a high degree of industrialization, developed infrastructure, technical advances, and a relatively high rank in human development, health, and more and it is that time of the year when they are required to submit the GDP data which includes per capita as well. Below is the information gathered by the statistician department: The population of the country is 956,899 as per the last census report available. Based on the information given you are required to calculate Real GDP per capita assuming that the deflator to be used is 18.50%.

  • Private Consumption: 1500000
  • Government Expenditure: 2250000
  • Exports: 750000
  • Imports: 1050000
  • Deflator: 18.50%
  • Population: 956.89


Here, the ministry is trying to calculate real GDP per capita but before that, we need to calculate real GDP and for that, we will first calculate the nominal GDP.

Nominal GDP 

Real GDP Per Capita Formula Example 2.1

Nominal GDP FormulaNominal GDP FormulaThe nominal GDP formula is used to figure out the nation's gross domestic product at the current price without considering inflation. It is the total of private consumption, gross investment, government investment and trade more = Private Consumption + Govt Expenditure + Exports – Imports

=  15,00,000k + 22,50,000k + 7,50,000k – 10,50,000k

  • Nominal GDP = 34,50,000k

Therefore, the calculation of Real GDP Per Capita will be as follows,

Example 2.2

= 34,50,000k / (1 + 18.50%)/ 956.89

Example 2.3

Example #3

The analyst is looking for the next developing country where she can invest the clients’ funds of approx. $140 million. She has shortlisted 3 developing countries and now wants to select the country where she can invest either in the stock market or the bond market. Her criteria to select the country with the highest real GDP per capitaReal GDP Per CapitaReal GDP Per Capita is the resulting value arrived by dividing the entire economic output of the whole country by the total number of people after adjusting the impact of inflation for comparison of the living standard amongst the more. Below are the details that she has collected.

Example 3

If the difference in the GDP per capitaThe GDP Per CapitaGDP per capita is a parameter that divides a country's GDP by its entire population to determine the economic prosperity of its more is less than 10k then she will invest the client’s funds in the ratio of real GDP per capita.

You are required to calculate the real GDP of the three countries and determine where she would be investing and what would be the allocation of $140 million of the investment amount.


Therefore, the calculation of Real GDP Per Capita will be as follows,

Example 3.1


Example 3.2

Similarly, we can calculate Real GDP Per Capita for remaining countries.

Real GDP Per Capita Formula Example 3.3

Now from the above calculation of Real GDP, we can notice that the differences between all of them are less 10k and hence she would be investing in all the three countries with a ratio of Real GDP per capita and the investment, therefore, shall be:

Real GDP Per Capita Formula Example 3.4
  • Investment Amount = 37369543.45

Similarly, we can calculate the investment amount for the remaining countries.

 Example 3.5

Relevance and Uses

It is widely used in the world to make a comparison of the standard of living across countries over a time period. Per capita would mean what is the GDP per person for that economy. The higher the figure the better it is. Nominal GDP includes inflation and hence when one makes the comparison of Nominal GDP over different time periods then it would also include growth with respect to inflation and which would inflate the growth rate and the real picture would be hidden. Hence, using real GDP removes the effect of inflation which makes comparison smother.
