DEFINITION of 'Price Inflation'. An increase in the price of a standardized good/service or a basket of goods/services over a specific period of time (usually one year).
The inflation rate is the rate at which prices for goods and services increase over a period of time. If the cost of goods and services decrease over a period of time, then it is known as deflation, which is just negative inflation. The base year for inflation is the year you want to compare the inflation rate from.
