Millennials choose—annuities?

It's probably no surprise that millennials are looking for guarantees, after the turbulent market times they've been living through. In addition, out of all age groups, they're the least prepared for retirement, with one out of every three saying they've saved no money toward retirement at all and a quarter of them saying that they owe more money than they've saved.

That kind of negative equity is pretty distressing, not to mention discouraging. And 18 percent say that their savings amounts to less than $5,000. Not exactly enough for a stay at the Ritz.

Whether they have managed to save money, or are only planning to, where do millennials think their retirement money will come from? Well, 46 percent say they're planning to use their personal savings to finance their retirement, while 43 percent cited a 401(k) and 30 percent said an individual retirement account.

But of course they're not the only ones who are ill-prepared to leave the workplace.

Scarier than millennials' lack of savings is that of seniors who haven't managed to put anything away for that long rainy day at the end of the job.

Despite the fact that net worth increases with age, the survey found that nearly 10 percent of seniors aged 70+ have less than $5,000 in savings.
