American Customer
Satisfaction Index

“In competitive markets, firms are rewarded by treating their customers well and punished for treating them badly. The rewards/punishments show up, not only in earnings, but also in stock prices and make equity markets better aligned with consumer utility, which, in turn, causes an upward shift in demand curves. As a result, consumer spending increases and so does economic growth,” – Claes Fornell, Founder and Chairman of ACSI – A Legacy of Innovations

Win on customer satisfaction;
Win in the marketplace

There is a straight line from customer satisfaction to corporate profitability and stock performance. Companies with top-level ACSI scores, and those changing satisfaction for the better, are today’s must-watch players.

The American Customer Satisfaction Index (ACSI) is a national indicator of the quality of economic output for goods and services as experienced by consumers of that output.

The Index uses technology developed at the University of Michigan by a team of researchers led by Claes Fornell, the Distinguished Donald C. Cook Professor of Business. Fornell is the most cited expert in the world on customer satisfaction and Customer Experience Management, according to Google Scholar. The Index currently tracks customer satisfaction with more than 400 of the largest corporations in the U.S. marketplace.

Findings from a large body of scientific research published by leading researchers from different academic institutions show that the American Customer Satisfaction Index has major effects on business objectives such as customer retention, corporate profitability, sales growth, size of cash flows, stability of cash flows, positive earnings surprises, stock returns, ROI, gross margins, shareholder value (Tobin’s Q), improved credit ratings, lower cost of capital, lower sales cost, and more. No other measure of customer satisfaction or customer experience has been able to demonstrate this kind of financial relevance.

Even more important, these financial returns are not associated with high risk. Not only is the doctrine of high risk/high return turned on its head, but customer retention economics produce exponentially increasing returns. As a result, another dogma—the law of diminishing returns—is also reversed (except for extraordinary high percentages of customer retention).

Because of the relevance of ACSI technology for business application—especially with respect to low risk/high return and exponentially increasing returns—the University of Michigan’s Office of Technology Transfer has made both the technology and ACSI data available to the private sector.

U.S. Overall Customer Satisfaction

In the 1990s, business focus on customer satisfaction was in its infancy and the satisfaction decline between 1994 and 1997 came at a time when profits were generated from efficiencies in production rather than from satisfied customers.
