GDP measured at current market prices without adjusting for inflation is called nominal GDP.
Nominal GDP values all final goods and services produced within an economy using the prices prevailing during the period being measured. It therefore changes when the quantity of output changes, when prices rise or fall, or when both happen at once. The term “current-price GDP” is often used as a synonym.
This contrasts with real GDP, which adjusts for price changes so economists can focus on changes in the volume of production. An economy can have higher nominal GDP even if it produces the same physical quantities, simply because prices increased. For that reason, nominal GDP is not by itself a reliable measure of real economic growth or living standards.
The GDP deflator helps connect the two concepts: it is commonly calculated as nominal GDP divided by real GDP, multiplied by 100. Another common mix-up is GDP per capita, which divides GDP by population but can still be either nominal or real. “Net GDP” instead subtracts depreciation from gross output.
