Is it possible to retire comfortably on Social Security alone? We asked seniors.

Is it possible to live comfortably in retirement on Social Security income alone?

Yes and no.

Alden and Dena Swartz draw nearly $4,000 a month from Social Security, the government program designed to support Americans in retirement. And they are struggling.

Gail Randle and her partner, Mike DellaVolpe, collect only $2,400 a month in Social Security benefits: Not quite $30,000 a year. And they are doing all right.

“We are frugal people,” said Randle, 73. “Almost everything in our house is recycled. Used, you know? Thrifted. But it looks nice. Everything works.”

Social Security was never intended to fund the full cost of retirement. On average, the benefit covers about 40% of a worker's preretirement earnings. And that figure could drop: Social Security will face a shortfall by 2035, according to the Congressional Budget Office. President-elect Donald Trump proposes to eliminate taxes on Social Security, which could deplete the fund two years sooner.

Most Americans think you need at least $1 million in the bank, on top of Social Security, to live a comfortable retirement. Investment firms and news headlines reward that thinking: Plan to save 10 times your annual income before you retire, common wisdom suggests, if you want to keep the lifestyle you have now.

But here’s the problem: Most Americans don’t save nearly that much. In the 65-to-74 age group, the typical family with a retirement account has about $200,000 saved, according to the federal Survey of Consumer Finances. Only about half of those households have retirement accounts at all.

And here’s the question: How are those people doing?

Just fine, says Andrew Biggs, a senior fellow at the American Enterprise Institute think tank. He penned an essay that went viral this year, arguing that you can retire with a lot less than $1 million in the bank: $50,000 to $100,000 in savings should do it, he said.

As evidence, Biggs points to another federal report, the Survey of Household Economics and Decisionmaking. That survey asked retirement-age Americans, 65 to 74, how well they were managing financially. Roughly 85% said they were doing OK.

After they retire, “people spend dramatically less,” Biggs said. “This sort of rat race you get when you’re working, a lot of that drops off in retirement.”

To test that theory, USA TODAY reached out to retirees across the country who are living mostly on Social Security and asked how they were doing. We got help from the r/retirement community on Reddit, whose 83,000 members talk about this stuff all the time.

Here’s what they told us.
