Explanation:
GDP is the total value of a country's output. Its calculation involves additions of all the finished goods and services produced in the economy per period. GDP is either expressed as either nominal or real. Nominal or stated GDP is the most commonly referred to when discussing economic growth.
Real GDP is nominal GDP adjusted for inflation. Calculation of real GDP involves the comparison of current GDP against the base year GDP. Real GDP gives a more realistic measure of economic growth as it accounts for changes in the price levels.
