GDP is the total value of all final goods and services, produced in an economy, during a particular period of time (usually a year). When this value gets adjusted for inflation, it becomes real GDP.
In other words, the inflation adjusted total value of all goods and services, produced in an economy, in a year is known as real GDP.
For measuring real GDP, first nominal GDP is measured of the given year. Then this value of nominal GDP is divided by GDP deflator of that year. The GDP deflator measures the level of prices of all new domestically produced goods and services, in that country during that year. GDP deflator is a measure of inflation.
