Definition of Consumer Price Index (CPI)
The Consumer Price Index (CPI) is a vital economic indicator that measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. It helps illuminate the inflation landscape and indicates how much more—or less—households should fork out at the checkout counter compared to previous periods.
