According to AARP data published in May 2026, the majority of 401(k) participants approaching retirement make one predictable mistake: they treat their lump sum like a salary replacement instead of a longevity vehicle.
“Once you reach retirement age, odds are good that you’ll live another 20 years or more,” AARP wrote in its April 2026 retirement security bulletin. “You need to find the right balance between drawing down your savings for income and making the money last.”
The organization reviewed distribution patterns from 12,400 retirement accounts between January and March 2026. What they found surprised their research team. Nearly 68 percent of first-time retirees withdrew more than 5.8 percent of their balance in year one, despite the widely accepted 4 percent guideline.
What the 2026 contribution limits actually mean for withdrawals
Higher contribution caps can create a false sense of security. Workers under 50 can now contribute up to $24,500 to a 401(k) in 2026, up from $23,500 in 2025. Savers aged 50 and older can add an extra $8,000 in catch-up contributions, bringing their total possible contribution to $32,500.
AARP confirmed that individuals ages 60 to 63 have a higher catch-up allowance of $11,250, for a maximum total contribution of $35,750.
The SECURE 2.0 Act expanded these catch-up limits specifically for people ages 60 through 63 to encourage increased retirement savings. However, the legislation did not address the behavioral gap between saving and spending.
The “4 percent rule” fails for one specific reason
The common guideline for retirement withdrawals suggests taking up to 4 percent of one’s investment portfolio in the first year of retirement, then adjusting that amount each year for inflation.
David Blanchett, head of retirement research at PGIM, published a longitudinal study in February 2026 tracking 3,200 retirees from 2010 to 2025. Participants who followed the 4 percent rule without adjusting for sequence-of-returns risk exhausted their portfolios 11 years faster than those who used dynamic withdrawal strategies.
AARP flagged this exact concern. “What’s the most important thing you can do to safeguard your retirement security?” the organization asked in its May 2026 member guide. “Contribute regularly to an employer-sponsored savings plan such as a 401(k).” But contributing is not the same as distributing. The two skills require completely different financial literacies.
A concrete example from Q2 2026 claims data
Between April 1 and May 14, 2026, Fidelity Investments processed 14,200 retirement distributions from clients aged 62 to 67. Their internal review, shared with AARP under data-sharing agreements, showed that retirees who used part of their 401(k) balance to purchase a qualified longevity annuity contract preserved 37 percent more spendable income by year ten compared to those who left funds in standard target-date funds.
The Roth 401(k) is a notable exception. “The exception is a Roth 401(k), which is funded with after-tax dollars and from which withdrawals in retirement are tax-free,” AARP wrote. “Thanks to some recent adjustments by the Internal Revenue Service, you can build that nest egg even bigger in 2026.”
Tax-free withdrawals eliminate the compounding drag of required minimum distributions, which currently start at age 73 under SECURE 2.0 rules.
Three withdrawal behaviors that predict success
The Employee Benefit Research Institute’s May 2026 Retirement Confidence Survey found that retirees who did the following three things reported 94 percent satisfaction with their income stability:
- They calculated their baseline essential expenses separately from discretionary spending.
- They kept two years of cash equivalents inside their portfolio to avoid selling during market declines.
- They used the remaining balance to purchase a deferred income annuity starting at age 80.
These savers also understood that these contribution limits apply to other workplace retirement plans, including 403(b) plans, 457(b) plans, and the federal Thrift Savings Plan.
The one question AARP says you must answer
“A 401(k) plan is a great way to increase your retirement savings,” AARP added in its 2026 retirement planner. “Your employer will deduct your pretax contributions from your paycheck, and your savings will be tax-deferred until you take withdrawals during retirement.”
But tax deferral creates a blind spot. Without a dedicated withdrawal strategy, higher contribution caps simply mean larger balances that retirees often mismanage at distribution. The question every 401(k) holder should answer before retiring is not how much they have saved, but how they will convert that balance into monthly income that outlives them.
