Older boomers save and plan for retirement differently than their younger counterparts. A survey from MetLife Mature Market Institute found the boomer “bookends” view retirement differently, however, both groups are underprepared.

Of boomers born in 1946, 19 percent have fully retired, and nearly two-thirds are still working. While only 13 percent have saved fully for retirement, 25 percent say they are on track. Over half say they have helped their children or grandchildren financially, providing an average $59,000 in the past five years.

Younger boomers, those born in 1964, want to retire by 64, although some believe they will have to put it off by at least a year. More young boomers (36 percent) are confident about their retirement savings than older boomers, and they are more likely to be caregivers.
