By Christina Cheddar Berk, CNBC News Editor NEW YORK ( CNBC) -- Fears that retirement will lead to a drop in one's standard of living due to insufficient savings isn't a concern restricted to the middle class, according to the findings of recent survey. Four in ten affluent Americans say their biggest fear about retirement is they "will do all the right things today and it still won't be enough for tomorrow" and 9% say they fear they have under saved and won't recover, according to a poll of 801 affluent Americans conducted by Harris Interactive for Wells Fargo Retirement. "I think we just assumed they would be in a better place for retirement," said Karen Wimbish, director of Retail Retirement at Wells Fargo.

Even among the affluent, 80 is the new 65. Nearly one in five with assets between $100,000 and $250,000 feel they will need to work until "at least age 80." Among all the affluent, 12% said they will work until 80 years of age. In the survey, Americans had to have investable assets of $100,000, excluding real estate and other property, to be considered affluent. The group surveyed was split evenly between Americans with between $100,000 and $250,000 and those with more than $250,000. --Written by Christina Cheddar Berk of CNBC.
