Nominal values versus real values
1
Nominal GDP
Values final output using current-period prices.
2
Real GDP
Measures output using a constant-price or equivalent volume framework.
3
GDP deflator
Nominal GDP ÷ real GDP × 100 when both are expressed on a compatible basis.
4
Inflation
A sustained increase in the general price level; it differs from output growth.
The connection A rise in nominal GDP can reflect prices, quantities or both.
Exam trap A falling inflation rate can still mean prices are rising, just more slowly.
Does lower inflation necessarily mean lower prices?
No. A lower positive inflation rate means slower price increases. Falling general prices would be deflation.

Inflation, GDP and Real Values — lesson overview
GDP: flow of production
Gross Domestic Product measures the value of final goods and services produced within a country’s domestic territory during a period, using the relevant national-accounting definitions.
Final goods are counted to avoid double counting intermediate production. GDP is a flow over time, not a stock measured at one instant.
Domestic production and the nationality of the producer are different concepts. GDP does not simply mean the income of all citizens wherever they live.
Nominal and real comparison
Nominal values use current prices; real values adjust for price changes using an appropriate reference framework. An increase in nominal output can result from higher prices, more output, or both.
For a simple illustration, producing 100 identical units at ₹10 gives ₹1,000. If the same 100 units later cost ₹12, nominal value rises to ₹1,200 even though physical output is unchanged.
Real growth aims to distinguish output change from price change. Actual national accounts involve many products and a more detailed methodology.
Inflation
Inflation is a sustained rise in the general price level, commonly measured as a rate of change in a price index. It is not merely the rise in one product’s price.
If an index rises from 100 to 106, its percentage increase is 6%. A fall in the inflation rate can still mean prices are rising, but more slowly.
Disinflation means slower inflation. Deflation means a fall in the general price level. A positive inflation rate of 3% after 6% is disinflation, not deflation.
