AP - The majority of American workers think they'll be able to retire comfortably, but most aren't saving nearly enough to meet that goal, according to a new study.

The Employee Benefit Research Institute's annual retirement confidence survey, released Tuesday, found that about 68 percent of workers are confident about having adequate funds for a comfortable retirement, up slightly from 65 percent in 2005.

At the same time, more than half of all workers say they've saved less than $25,000 toward retirement, according to the Washington, D.C., based research group. Even among workers 55 and older, more than four in 10 have retirement savings under $25,000.

"`Overconfidence' is the word that comes to mind," said Jack VanDerhei, co-author of the study.
