The GDP deflator is an economic indicator used to measure the level of inflation in an economy. It is calculated as the ratio of nominal GDP to real GDP, multiplied by 100. Nominal GDP represents the value of all goods and services produced in an economy at current market prices, while real GDP is adjusted for inflation and represents the value at constant prices. The GDP deflator, therefore, reflects the price changes of all goods and services included in the GDP.

The GDP deflator is a broader measure of inflation than the Consumer Price Index (CPI) because it includes all goods and services produced domestically, not just those consumed by households. This means it accounts for changes in the prices of capital goods, government purchases, and exports, in addition to consumer goods and services. A rising GDP deflator indicates that the overall price level in the economy has increased, meaning inflation is present. Conversely, a falling GDP deflator would suggest deflation.

Economists use the GDP deflator to understand the true growth of an economy by stripping out the effect of price changes. It is also used to compare economic output across different time periods and to make international comparisons of economic performance. The calculation involves dividing the nominal GDP of a given year by the real GDP of the same year and then multiplying the result by 100. The base year typically has a GDP deflator of 100.
