Investopedia explains 'Real Gross Domestic Product (GDP)'
Unlike nominal GDP, real GDP can account for changes in the price level, and provide a more accurate figure.
Let's consider an example. Say in 2004, nominal GDP is $200 billion. However, due to an increase in the level of prices from 2000 (the base year) to 2004, real GDP is actually $170 billion. The lower real GDP reflects the price changes while nominal does not.
