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).
Inflation is the change in the price level from one year to the next. The change in inflation can be calculated by using whatever price index is most applicable to the given situation. The two most common price indices used in calculating inflation are CPI and the GDP deflator. Know, though, that the inflation rates derived from different price indices will themselves be different.
