Nominal GDP vs. Real GDP — What's the Difference?

Conversely, Real GDP accounts for inflation or deflation, offering a more accurate representation of an economy’s size and how it’s growing over time. Real GDP is calculated using prices from a base year to provide a more realistic perspective on economic growth and productivity, disregarding price changes. Thus, Real GDP is a more reliable metric when comparing economic growth over different time periods or between different economies as it reflects the real quantity of goods and services produced.

These metrics are significant for governments, policymakers, and economists to formulate economic policies, understand economic health and growth, and make international comparisons. While Nominal GDP might be easier to calculate and helpful for year-to-year comparisons, Real GDP provides a deeper insight into the economic well-being of a nation, revealing the actual increase in production and services.

Nominal GDP and Real GDP are pivotal components for economic analysis, providing different perspectives on a country's economic performance and growth.

Nominal GDP refers to the total market value of all goods and services produced within a country in a specific time period, usually a year, without adjusting for inflation or deflation. It's evaluated at current market prices, incorporating all the changes in market prices that have occurred during the current year due to inflation or deflation. For instance, if there's significant inflation, Nominal GDP might give an impression of economic growth when, in actuality, the output might not have increased.
