And fewer than half of boomers and GenXers are confident that they’ll be able to retire when they want; they’re also worried about having enough assets to last through retirement. Those who are extremely worried cite health care and taxes as their two chief concerns.

Retirement plan providers, the study said, will find that their own roles are changing.

Just 47 percent of WWII participants said that they are better off now. And while 84 percent of millennials say that next year will be even better, only 43 percent of the older generation agreed.

Only 49 percent of participants overall think they’ll have enough money to last through retirement—but surprisingly enough, 64 percent of millennials and 65 percent of WWII participants think so, compared with only 39 percent of GenXers. Health care costs are the chief reason they feel they may fall short.

Most participants feel they’ll have less than $1 million in investable assets when they retire; of those, 36 percent say they’ll have less than $500,000, while 35 percent think they’ll have between $500,000 and $1 million. Fifty-seven percent say that a greater income will give them the biggest financial boost, while 49 percent say that cutting spending and budgeting more tightly will improve their wealth position.
