Of those aged 50 to 64, 15 percent say they're saving more, compared to 21 percent who say they're saving less than they were last year.
Not enough for a comfortable retirement
Lest you think Americans are pulling back on saving because they've already saved enough, 40 percent of American households near retirement age have no retirement account at all, according to Federal Reserve data released in 2012.
Among the 60 percent in that age group (55-64) who have retirement accounts, the median balance is about $100,000, the Fed said. That may sound substantial, but it's not enough to allow many people to maintain their standard of living throughout retirement, says Gary Koenig, director of economic security at the AARP Public Policy Institute.
"It's not even close," Koenig says. "People underestimate what their needs are going to be when they're older, (and) underestimate how long they're going to live. I think they overestimate how much a pot of money that they build up in their 401(k) will translate into in terms of your lifetime income."
Why we don't save
There are a number of things that might be pushing retirement savings to the back burner in American households.
After five years of serious economic hardship for many Americans, it's likely they have trouble finding room to save in their budgets at all, says Henning Bohn, professor of economics at the University of California, Santa Barbara.
"People have to struggle enough to make a living, and so it's difficult to set aside enough," Bohn says. "You can imagine someone who's losing their house is not going to be worried about retirement 10 years down the road. They're worried about a roof over their head over the next year.
"It stands to reason that people who are unemployed will have a hard time saving. Some people will be tempted to even cash out their retirement funds -- their 401(k)s and 403(b)s -- in order to survive during unemployment," he adds.
Wade Pfau, professor of retirement income at The American College in Bryn Mawr, Pa., agrees.
'In the back of their mind'
"People have so many demands on their resources today that when they're looking at the different priorities; something that's well off in the future they can kind of put off in the back of their mind," Pfau says. "A lot of people are not accumulating the assets they need to implement the lifestyle they would like in retirement."
Data collected since the Financial Security Index began in 2010 seem to show older Americans have been hit especially hard by the economy, and that may be a key factor in why they're lagging on retirement saving, says Bankrate's McBride.
"They have routinely had the lowest feelings of job security, relative to every other age group, they have low comfort level with their savings and even net worth," McBride says.
Shocked by stocks
Even for those with the means to save and invest for retirement, making the decision to do so isn't always a slam-dunk.
For instance, demoralizing hits to the stock market tend to discourage retirement savings, says Frank Stafford, a professor of economics at the University of Michigan in Ann Arbor.
Stafford's research suggests that after major downturns on Wall Street, the number of Americans who contribute to 401(k) plans drops dramatically.
"You got these very noticeable impacts in participation after the dot-com bubble and then after the 2008 crash," Stafford says.
Those who don't stop saving entirely often end up switching into cash or fixed-income investments right before a subsequent recovery in stock prices, he says, hurting their ability to meet retirement needs.
One factor that seems to reduce those effects is education. Americans with lower levels of education tended to experience the biggest capital losses in a downturn, Stafford says.
Retirement in transition
The potholes in the road to a comfortable retirement are in many ways the product of a painful transition in retirement funding that's taken place since the 1970s, says Koenig.
Back then, around half of private-sector workers and most public-sector workers had pensions guaranteed for life. When added to Social Security income, it meant a comfortable retirement, even with little private saving on the part of retirees, Koenig says.
Now, thanks to a transition among business from traditional pensions to 401(k)s and laws pushing back the full retirement age and increasing the taxability of Social Security payouts, much of the retirement responsibility is being left to Americans themselves. And thanks to rising health care costs and increasing longevity, that burden is heavier than ever, says Koenig.
"You have all these factors … that are really making it more challenging to maintain your standard of living in retirement," Koenig says.
What to do
Here are some tactics Pfau says could help those who are behind on their retirement saving:
- Save as much as your budget will allow, to make up some ground.
- Hold out on taking Social Security until you're 67, to reap a higher monthly benefit.
- Take out a reverse mortgage on your home.
- Plan to work part time as you begin retirement.
The key thing is to deal with the issue rather than putting it off, says McBride.
"You hear people just sort of sigh deeply and say, 'Well I guess I'll work forever,'" he says. "That's not realistic. Health issues can get in the way. An economic downturn can get in the way. You don't ultimately get to make that decision."
