Both the contract interest rate and the annual percentage rate indicate the
price of a loan. Consumer's understanding of these two measures of the pri
ce of closed-end consumer loans was examined using the 1997 University of M
ichigan Survey of Consumers. Among the mortgage borrowers, at least 40% of
respondents failed to understand the relationship between these two price m
easures; education, quantity and quality of information search, and region
were found to influence their understanding. The authors draw implications
for improving information disclosure in consumer credit markets.
