Real personal consumption expenditures (PCE) is the primary measure of consumer spending on goods and services in the U.S. economy. This chart shows the real (or inflation-adjusted) level of expenditures, broken down by durable goods, nondurable goods, and services. Durable goods have an average useful life of at least 3 years (e.g. motor vehicles) while nondurable goods have an average useful life of less than 3 years (e.g. food). Services are commodities that cannot be stored or inventoried and are consumed at the time of purchase (e.g., dining out). Roughly two-thirds of the total U.S. economic output is through consumer spending.
