GDP is the acronym for Gross Domestic Product and refers to the income accumulated by a country from sales of goods and services in a given period, which is usually a quarter, a semester or a year.
Income is calculated based on what is generated by natural and legal persons that live within the country, regardless of their nationality or country of origin of the company.
GNP is the acronym for Gross National Product, a macroeconomic value to measure the income generated by the sale of goods and services carried out by natural and legal persons who live in the country, regardless of their nationality or the origin of the company.

The Gross Domestic Product (GDP) is a macroeconomic variable that is used to measure the monetary value of all the products and services generated by a country during a period, generally one year. The function of this indicator is to evaluate the growth or decline of a country.
The GDP takes into account the income from the production of the productive factors found within the country, regardless of their nationality..
For example, a French car assembler is based in Mexico. What is produced in that country will be part of its GDP, even if the company is of French origin.
There are three types of GDP:
1 GDP per capita
Values the products and services produced by a country based on its number of inhabitants.
2.Nominal GDP
It is the monetary value of the products and services produced by a country at current prices, that is, at current market prices. These prices are subject to the variations (inflation or deflation) of the period studied.
3.Real GDP
It is the value of the products and services generated by a country considering the inflation of the analyzed period. It allows to know if the value of a product rose because the economy is strengthening or if it is due to a price variation.
GDP deflator
It is a macroeconomic index that measures price variations as a function of GDP. Since nominal GDP takes inflation into account and real GDP does not, the GDP deflator helps correct any deviations that can arise from using GDP as a macroeconomic indicator..
Each of the types of Gross Domestic Product has its own formulas, as does the GDP deflator, which is key to knowing the real GDP.
Nominal GDP formulas
There are three methods for calculating nominal GDP:
The formula, then, would be:
GDP = C + I + G + (Ex - Im)
An example of GDP calculated with this method could be (in trillions of dollars):
GDP = 3,000 + 120,000 + 60,000 + (4750-2550)
GDP = 183000 + 2200
GDP = 185,200 trillion USD
The formula includes the income of the workers, the income from the income of the companies' assets, called Gross Operating Surplus, and the value obtained after subtracting the government subsidies from the income obtained from taxes. Would:
GDP = Workers' income + E.B.E + (Taxes - subsidies)
An example of GDP calculated with the income method would be (in trillions of dollars):
GDP = 14000 + 7400 + (8900-5320)
GDP = 21400+ 3580
GDP = $ 24,980 trillion
GVA = value of sales - intermediate consumption value
This is done so that only the raw material values remain, and are not added back to the finished product.
With that value, and the value obtained after subtracting government tax subsidies, this formula remains:
GDP = GVA + (Taxes - Subsidies)
An example of GDP with the value added method would be:
GDP = 27,850 + (12,500 - 7,400)
GDP = 27,850 + 5100
GDP = $ 32.95 billion
Real GDP formula
Real GDP is calculated by dividing nominal GDP by the GDP deflator. Therefore:
Real GDP = Nom GDP / GDP Deflator
An example of real GDP calculation would be (in trillions of USD)
Real GDP = 519 / 2064.92
Real GDP = 251 MM USD
GDP per capita formula
The formula for calculating GDP per capita takes the account of nominal GDP and is as follows:
GDP pc = GDP (nominal) / number of inhabitants.
An example of calculating GDP per capita is that of Mexico in 2018, which had a GDP of 1,221 trillion dollars and 126.2 million inhabitants. Then,
GDP pc = 1221 / 126.2
GDP pc = 9673 trillion USD.
GDP deflator formula
The GDP deflator formula requires knowing the nominal and real GDP of a country. Then:
GDP deflator = nominal GDP / real GDP x 100
For example, if a country's nominal GDP in 2010 was $ 1.750 trillion, and its real GDP was $ 1.3 trillion, the calculation would be:
GDP deflator = 1750/1300 x 100
GDP deflator = 1.34 x 100
GDP deflator = 134 trillion USD
The Gross National Product is a macroeconomic variable that is used to measure the monetary value of the products and services generated by the residents of a country during a period, generally one year..
Residents are all natural or legal persons living in a country, regardless of their nationality.
For example, a Mexican lecturer goes on a tour of Germany. The income it generated is part of the Mexican GNP but not of the GDP, since they correspond to the calculation of the German GDP.
The formula to calculate the Gross National Product requires knowing the country's GDP, the value of national production and the value of foreign production carried out in the country. Then,
GNP = GDP + Pn - Pex
An example of a Gross National Product calculation would be (in billions of dollars)
GNP = 1221 + 934 - 693
GNP = 2155 - 693
GNP = USD 1,462 trillion.
In closed economies, in which there are no commercial links with abroad, only the Gross Domestic Product is taken as a reference.
