Core Inflation

AAA

DEFINITION of 'Core Inflation'

A measure of inflation that excludes certain items that face volatile price movements. Core inflation eliminates products that can have temporary price shocks because these shocks can diverge from the overall trend of inflation and give a false measure of inflation.

INVESTOPEDIA EXPLAINS 'Core Inflation'

Core inflation is most often calculated by taking the Consumer Price Index (CPI) and excluding certain items from the index, usually energy and food products. Other methods of calculation include the outliers method, which removes the products that have had the largest price changes. Core inflation is thought to be an indicator of underlying long-term inflation.
