Nominal GDP
Quick Definition
Gross domestic product measured at current market prices without adjusting for inflation.
Key Takeaways
- Measured at current market prices — includes inflation effects
- Can overstate real growth during high-inflation periods
- Real GDP = Nominal GDP adjusted for inflation using a deflator
- Still useful for debt ratios and current-period financial comparisons
What Is Nominal GDP?
Nominal GDP measures a country's total economic output valued at current prices in the period being measured, without any adjustment for inflation or deflation. It reflects both changes in real output (quantity of goods and services) and changes in the price level. Because nominal GDP includes price effects, it can overstate real economic growth during inflationary periods and understate it during deflationary periods. For example, if an economy produces the same quantity of goods but prices double, nominal GDP doubles even though real output is unchanged. To isolate genuine growth in production, economists use real GDP, which removes the inflation component using a base-year price level or chain-weighted deflator. Nominal GDP is still useful for certain comparisons, such as debt-to-GDP ratios.
Nominal GDP Example
- 1U.S. nominal GDP grew 10% in 2021, but after subtracting 4.7% inflation, real GDP growth was approximately 5.7%.
- 2A country with 3% real growth and 8% inflation would report approximately 11% nominal GDP growth.
- 3Government debt-to-GDP ratios use nominal GDP because debt is denominated in nominal terms.
