Many “near retirees” are as uncertain about how they will go about retiring as younger people are.

Researchers at Guardian Life Insurance Company of America, New York, have published data supporting that conclusion in a summary of results from a recent survey of 1,006 U.S. adults ages 18 and older who work at least part time.

Guardian commissioned the survey to look at the role of whole life insurance in financial planning.

The researchers found that 40% of the participants ages 44 and under said they believe they will be able to save less than half of what they will need to retire or do not know how much they will be able to save for retirement.

But the researchers also found that about one-third of the participants in the 55-64 age category are in the same boat: They also are doubtful about their ability to accumulate more than half of the cash they need to retire.

Whole life ownership seems to make a difference in retirement readiness, the Guardian researchers contend.

Only 60% of the participants without whole life say they believe they will have enough money to live comfortably during retirement, but 80% of the participants with whole life believe they will be able to pay for a comfortable retirement, the researchers report.
