消費者物價指數(CPI)
A consumer price index (CPI) is an index number measuring the average price of consumer goods and services purchased by households. It is one of several price indices calculated by national statistical agencies. The percent change in the CPI is a measure of inflation. The CPI can be used to index (i.e., adjust for the effects of inflation) wages, salaries, pensions, or regulated or contracted prices. The CPI is, along with the population census and the National Income and Product Accounts, one of the most closely watched national economic statistics.

消費者物價指數(英文:Consumer Price Index,缩写CPI,亦称居民消费价格指数),在经济学上,是反映与居民生活有关的产品及劳务价格统计出来的物价变动指标。它是衡量通货膨胀的主要指标之一。

CPI是一个固定的数量价格指数并且无法反映商品质量的改进或者下降,对新产品也不加考虑。美国的消费者物价指数是涵盖了房屋支出、食品、交通、医疗、成衣、娱乐、其它等七大类商品的物价来决定各种支出的权数。

CPI若扣除食物與能源的統計數字,此數據稱為「核心物價變動率」,當核心物價變動率低於3%時,經濟成長率應是處於相對低的水準。
