What Is Real GDP?

Real GDP measures economic output in constant prices, removing the distorting effects of inflation or deflation to reveal genuine changes in the quantity of goods and services produced. It is calculated by deflating nominal GDP using a price index (typically the GDP deflator or chain-weighted price index). Real GDP is the standard measure used to compare economic growth across time periods and is the basis for determining whether an economy is in recession (commonly defined as two consecutive quarters of negative real GDP growth). The U.S. Bureau of Economic Analysis reports real GDP in chained 2017 dollars. Real GDP growth rates provide the most accurate picture of whether an economy is producing more or fewer goods and services, independent of price changes.

Real GDP Example

  • 1U.S. real GDP contracted 3.4% in 2020 during the pandemic, then rebounded 5.7% in 2021.
  • 2If nominal GDP grows 8% and the GDP deflator shows 5% inflation, real GDP growth is approximately 3%.
  • 3Two consecutive quarters of negative real GDP growth is the common (though unofficial) definition of a recession.
