At 68, most people are either newly retired or close enough that the math has to start working. Social Security is already in the picture. Medicare has kicked in. And the question that once felt abstract — "do I have enough?" — has a real deadline. For many Americans, that deadline arrives sharply when they look at the number in their 401(k).
The honest answer is that most people at this age are carrying far less than retirement planning guidelines suggest they should. And understanding the gap — between what you have, what you need, and what you can still do about it — starts with knowing where you stand financially.

What the data shows
According to Fidelity, the average 401(k) balance for Americans 65-69 is $258,800, similar to the average 401(k) balance by age for people just a few years into retirement. The overall average across all ages is $141,000, which means this older cohort has significantly more saved than most. But the average is a deceptive number: a relatively small group of high-balance savers pulls it upward considerably.
The median tells a more honest story. Vanguard's "How America Saves" 2025 report, which draws on data from nearly 5 million plan participants, puts the median 401(k) balance for Americans 65 and older at $88,488. That's the midpoint — half of savers in this group have less. For most people approaching or entering retirement, six figures in a 401(k) is closer to the real picture than three hundred thousand.
The benchmark you're probably not hitting
Fidelity's widely cited rule of thumb calls for saving 10 times your annual salary by age 67. On an $80,000 income, that's $800,000. On a $60,000 income, it's $600,000. Either way, a median balance of $88,488 — or even an average of $258,800 — falls well short.
Those milestones assume you've been saving 15% of income since your mid-20s, investing a majority in equities, and retiring at 67. Most people didn't start that early, didn't save at that rate, and may have taken years off the workforce. The benchmark is aspirational, but it frames the gap clearly.
What $258,800 actually buys in retirement
The standard financial planning assumption is the 4% withdrawal rule, which suggests withdrawing 4% of your savings annually to minimize the risk of outliving your money. Applied to a $258,800 balance, that's roughly $10,352 per year — about $863 a month.
Add the average Social Security retirement benefit of $2,081 per month (as of April 2026), and a typical retiree relying on these two sources is looking at roughly $2,944 per month in income.
The problem is spending. According to the Bureau of Labor Statistics' most recently published Consumer Expenditure Survey — covering 2024 and released in December 2025 — households headed by someone 65 or older spent an average of $61,432 per year — roughly $5,119 per month.
That leaves a gap of $2,000 or more per month between what a typical retiree with average savings brings in and what the average retiree actually spends. It's a shortfall that compounds quickly over a 20- to 25-year retirement.

The RMD clock is also ticking
One more pressure point for people at 68: required minimum distributions. Under SECURE 2.0, most Americans must begin withdrawing from their 401(k) at age 73 — five years away for a 68-year-old. That means the window for strategic Roth conversions or tax planning is still open, but it's narrowing.
If you haven't thought about how RMDs will affect your tax situation in retirement, now is the time. Large required distributions in your 70s can push you into higher tax brackets and affect Medicare premiums.
What you can still do
If you're still working, the 2026 contribution limits offer a meaningful opportunity. Workers 50 and older can take advantage of the 2026 401(k) catch-up contribution rules, which allow up to $32,500 total this year — $24,500 in standard contributions plus an $8,000 catch-up. If you're between 60 and 63, SECURE 2.0 allows an enhanced catch-up of $11,250 instead, bringing the total to $35,750. Even a few years of maxing these out can meaningfully close a gap.
For those already retired, the levers are different but real. Home equity — whether through downsizing, a HELOC, or a reverse mortgage — represents a significant asset for many older Americans that often goes untouched. Part-time or consulting work, even for a few years, can both supplement income and delay drawing down your portfolio. And a disciplined look at spending, particularly in discretionary categories, can stretch a fixed income further than most people expect.
Bottom line
The average 401(k) balance at 68 sounds like a reasonable sum until you run the numbers. At a 4% withdrawal rate, $258,800 generates about $863 a month — and combined with the average Social Security check, that's roughly $2,944 total against a typical monthly spending tab north of $5,000.
The gap is real, but it's not necessarily permanent: higher contribution limits, home equity, and even modest spending adjustments can all stretch your retirement dollar further. The worst response is to ignore the math and hope it resolves itself.
FAQs
What happens if you miss a required minimum distribution?
The IRS charges a penalty of 25% of the amount you should have withdrawn. If you correct the mistake quickly, that penalty can be reduced to 10%. You'll still owe ordinary income tax on the RMD amount itself, on top of the penalty.
Can you still contribute to a 401(k) at 68 if you're still working?
Yes, if you're employed and don't own more than 5% of the company, the IRS allows you to keep contributing and even delay RMDs from that specific employer's plan until you actually retire. This exception doesn't apply to IRAs or to old 401(k)s from previous employers.
Is a 401(k) the only way to save for retirement at 68?
No, IRAs, taxable brokerage accounts, home equity, pensions, and part-time work can all supplement retirement income. Many retirees rely on a mix of these sources rather than a single account.
