The Consumer Confidence Index is the result of a monthly survey of 5,000 U.S. households by the Conference Board that measures how optimistic or pessimistic consumers are about the economy’s current and future performance. When the index is high, consumers are expected to increase their spending on goods and services. When it is low, a decrease in spending is expected. Since consumer spending accounts for about two-thirds of gross domestic product, consumer confidence is an important indicator of where the economy might be headed.The Consumer Confidence Index, or CCI, has a benchmark value of 100. Analysts can view CCI data by consumer age, income and census region. Opinions on current conditions make up 40% of the index, with expectations of future conditions comprising the remaining 60%. The board calculates a relative value for each question by dividing the total positive responses by the total positive and negative responses. These values are averaged and then compared against the benchmark value of 100 to create the current index value.
