Economists use the BEA's real GDP headline data for macroeconomic analysis and central bank planning. As the table above indicates, the main difference between nominal GDP and real GDP is the taking of inflation into account. Since nominal GDP is calculated using current prices, it does not require any adjustments for inflation. This makes comparisons from quarter to quarter and year to year much simpler to calculate and analyze. Keep in mind, though, that any comparisons are less relevant.

As such, real GDP provides a better basis for judging long-term national economic performance than nominal GDP. Using a GDP price deflator, real GDP reflects GDP on a per-quantity basis. Without real GDP, it would be difficult to identify just from examining nominal GDP whether production is actually expandingor it's just a factor of rising per-unit prices in the economy.
