Powerful Science, Proven Results
The American Customer Satisfaction Index (ACSI) is the only national cross-industry measure of customer satisfaction in the United States. The Index measures the satisfaction of U.S. household consumers with the quality of products and services offered by both foreign and domestic firms with significant share in U.S. markets. The ACSI benefits business, researchers, policymakers, and consumers alike by serving as a national indicator of the health of the U.S. economy, as well as a tool for gauging the competitiveness of individual firms and predicting future profitability.
The American Customer Satisfaction Index provides unique customer experience benchmarking capabilities that come from the Index’s one-of-a-kind, cross-industry structure. For over two decades, the ACSI has used its science-based, proprietary methodology to analyze customer satisfaction for 10 economic sectors and 45 key industries that together represent a broad swath of the national economy.
The ACSI produces customer satisfaction benchmarks for 45 industries and 10 economic sectors. Each industry-level customer satisfaction benchmark consists of the average of that industry’s company scores, weighted by company revenues. Likewise, each sector-level customer satisfaction benchmark consists of the average of that sector’s industry scores, weighted by industry revenues.
