Term price level Definition: The average of the prices of goods and services produced in the aggregate economy. In a theoretical sense, the price level is the price of aggregate production. In a practical sense, the price level is measured by either of two price indexes, the Consumer Price Index (CPI) or the GDP price deflator. The CPI is the price index widely publicized in the media and used by the general public. The GDP price deflator, in contrast, is less well-known, but is usually the price index of choice among economists. The inflation rate is calculated as the percentage change in the price level.
