The University of Michigan consumer confidence index rose to 72.8 from 71.
The Delta strain, high prices and persistent health concerns continue to weigh on consumer confidence.
The US consumer confidence index rose slightly at the end of September, but it is still close to its lowest level since the outbreak, and Americans are slightly more optimistic about the state of the economy.
Data released on Friday showed that the University of Michigan's consumer confidence index rose to 72.8 from an initial 71, exceeding the median forecast of economists surveyed by Bloomberg, which stood at 70.3 in August.
"Consumer confidence rose slightly at the end of September, but overall optimism remained suppressed, initially affected by the spread of the Delta strain and later due to soaring inflation and a poor long-term economic outlook," Richard Curtin, which is in charge of the survey, said in a statement.
The slight rebound in consumer confidence suggests that concerns about Delta are beginning to abate as new cases fall in most states. While high prices and persistent health concerns continue to weigh on consumer confidence, overall consumer spending remains high.
The University of Michigan report shows that because of high prices, conditions for purchases of homes, cars and durable goods have deteriorated from August, but buying of durable goods has improved from the beginning of last month.
Consumers expect inflation to be 4.6% in the coming year and rise to 3% over the next five years, up from 2.9% forecast in August.
According to the survey conducted from 25 August to 27 September, the current status indicator rose from the initial 77.1 to 80.1 and the future expected indicator rose to 68.1.
Respondents believe that the current financial situation is more favourable than in August. For the next five years, only 44% of respondents expect their financial situation to improve, the lowest percentage in seven years.
