Which GDP measure is adjusted for changes in price levels over time?

Real GDP is the measure adjusted for changes in price levels over time. It uses a price index (like the GDP deflator or base-year prices) to value output at a constant price, removing the effects of inflation or deflation. This lets you compare actual production across years, not just changes driven by price changes. For example, if nominal GDP rises 5% but inflation is 3%, real GDP grows about 2%, reflecting real increases in output rather than higher prices. Nominal GDP uses current prices and thus shifts with inflation, potential GDP is about the economy’s sustainable capacity, and GDP can be reported in nominal or real terms—the real version specifically accounts for price level changes.
