What is the Gross Domestic Product?

GDP is the final value of the goods and services produced within the geographic boundaries of a country during a specified period of time, normally a year.

GDP growth rate is an important indicator of the economic performance of a country.

To avoid double counting, GDP includes the final value of the product.

The calculation method of GDP is
Personal Expenditure + Gross Investments + Government Spending + (Exports-Imports)

When the economists talk about the size of the economy, it indicates GDP

Nominal GDP – This is the raw measurement that includes price increases

Real GDP – Real GDP is arrived after removing the inflation effects from nominal GDP. Hence real GDP will always be lesser than the Nominal GDP. 

Growth Rate – The GDP growth rate is the percentage increase in GDP from quarter to quarter

GDP per capita – It can be arrived dividing GDP by the number of residents. It is a good measure of living standard in a country

2. GDP also does not cover the black economy.
3. GDP does not include unpaid services
