For many older Americans, Social Security serves as a crucial source of retirement income. But for a good chunk of seniors, those monthly benefits are the only income they have.
If you’re struggling to save for retirement, you may be wondering if it’s possible to live on Social Security alone. The answer is that it’s possible. But it may not be comfortable — at all.

What retiring on Social Security alone means today
The amount of money Social Security pays you each month in retirement will hinge on different factors, including your personal wage history and filing age. As of February 2026, the average monthly Social Security retirement benefit was $2,076.41. When we multiply that by 12, we come to an annual income of about $25,000.
Now it may be that you’re eligible for a larger Social Security benefit than that. But even so, in 2026, the maximum Social Security benefit at full retirement age is $4,207. If we multiply that by 12, it’s about $50,500 a year.
Meanwhile, Motley Fool research found that in 2025, Americans of retirement age had a median income of $54,710. But it also found that their annual spending was $60,087 on average. This means that even if you were to snag the largest Social Security benefit at full retirement age, you’d probably still end up with a shortfall on your hands.
It’s best to have a variety of income streams
Retiring on Social Security alone may technically be possible, especially if you don’t have large expenses. But remember, the expenses you start out in retirement with may not be the expenses you end up with.
You could end up needing to spend more on healthcare as you age. And as your home gets older, it might need repairs.
Even if your expenses hold pretty steady in retirement, having only Social Security could mean having to stick to a very restrictive budget. That may not be an enjoyable way to live.
For these reasons, it’s best to have income outside of Social Security. If you’re struggling to save for retirement, try boosting your income with a side gig. Working even a few hours a week could make it possible to make modest, steady contributions to an IRA or 401(k). Over time and with the right investments, those efforts could pay off.
If you’re nearing retirement without savings, continue to work a bit once your main career comes to an end. You can take a part-time job, do gig work, or consult in your former field. That, too, gives you income on top of Social Security you can use.
Social Security is meant to be a safety net for retirees. But you should aim to not have it be your only source of retirement income. If you retire on just Social Security, you may find that you don’t have a lot of financial breathing room. And that’s a tough situation to be in for decades.
