The $257,400 Question: Is Your 401(k) at 60 Enough for Retirement

The five years around age 60 hold an unusual amount of tax leverage. Contribution limits change, Roth conversion windows open, Social Security timing decisions firm up, and the first preview of required minimum distributions starts to take shape. Each lever pulled or skipped during this stretch echoes for decades through the size of every check, withdrawal, and tax bill that follows. The data below sketches what the average pre-retiree is actually working with and which choices carry the most weight.

What the average 60-year-old is working with

The starting point matters because it shapes which levers are even available. Fidelity’s most recent Q1 2026 retirement data puts the average 401(k) balance at $257,400 for the 60 to 64 age bracket, climbing only slightly to $258,800 for ages 65 to 69. Fidelity’s own guideline suggests saving eight times one’s salary by age 60, so a household earning $90,000 would target roughly $720,000. The gap between that benchmark and the typical actual balance is wide, which makes every dollar lost to avoidable taxes more consequential.

Spending pressure has not eased. The Bureau of Labor Statistics put average annual household expenditures at $78,535 in 2024, and the personal savings rate slipped from 6.2% in early 2024 to 3.9% in the first quarter of 2026. Consumer prices continued to climb, with the CPI index reaching 333.979 in May 2026, up from 321.435 a year earlier. Any fixed-income strategy built at age 60 must be durable enough to withstand that kind of ongoing erosion.

Lever one: the super catch-up at 60 to 63

The 2026 401(k) employee limit is $24,500 for workers under 50 and $32,500 for those 50 and older. For the narrow four-year window covering ages 60 through 63, the limit jumps to $35,750, courtesy of an enhanced catch-up of $11,250 that the SECURE 2.0 Act created. A worker in the 22% federal bracket (single filers with taxable income between $48,476 and $103,350 in 2025) who uses the full super catch-up pushes an extra $11,250 into a tax-deferred account while trimming the current year’s tax bill at a known rate. That extra room closes the year a participant turns 64, so the window is shorter than it looks.

The IRA limit is $8,600 in 2026 for those 50 and older, reflecting a $1,100 catch-up on top of the $7,500 standard limit. Under SECURE 2.0, workers whose FICA wages exceeded $150,000 in 2025 must route all 2026 catch-up contributions into a Roth 401(k). The math shifts from a deduction today to tax-free income later, which changes how that contribution fits into a broader conversion strategy.

Lever two: the Roth conversion window

The years between leaving full-time work and starting Social Security and RMDs are often the lowest-income years of an adult’s life. Converting traditional IRA or 401(k) balances to Roth during that gap means filling up lower brackets at rates that are currently known. The 12% bracket runs to $48,475 for single filers and $96,950 for joint filers in 2025. Conversions completed before age 73, when RMDs begin under current law, shrink the future taxable balance and every RMD that follows. Skipping this window tends to be costly: later withdrawals stack on top of Social Security income, often pushing more of that benefit into taxable territory.

Lever three: when to claim Social Security

The age at which a retiree files a claim shapes the size of every check for life. Filing at 62 reduces the full retirement age benefit by about 30% for anyone born in 1960 or later, while delaying past full retirement age adds roughly 8% for each additional year, up to age 70. The 2026 cost-of-living adjustment was 2.8%, and advocacy groups are now projecting the 2027 COLA at roughly 3.5% to 3.6%, though the official figure will not be announced until mid-October. The COLA compounds on whichever base benefit a recipient locks in at filing, so delaying produces a larger check that a larger COLA is then applied to, every year, for the rest of the retiree’s life.

Lever four: where to hold income-producing assets

The rate environment has shifted meaningfully since mid-year, making asset location more consequential than it has been in some time. The 10-year Treasury yield climbed to roughly 4.97% as of September 11, 2026, up from 4.41% in late June, and briefly touched 5% for the first time since October 2023. The federal funds rate sits at 3.63%, with futures markets pricing in at least one additional hike before year-end. Interest income is taxed as ordinary income at the federal level, so holding bonds and CDs inside a traditional IRA defers that tax, while Roth accounts shelter it permanently. Taxable brokerage accounts are generally better suited to equities held for long-term capital gains and qualified dividends, where lower tax rates apply.

The close

The window between roughly 58 and 63 is short, and the decisions made inside it cannot be revisited. Filling the 60-to-63 super catch-up, executing Roth conversions during low-income years, and carefully modeling the Social Security claiming-age tradeoff against actual portfolio income are the three concrete moves the data points to. Higher Treasury yields add a fourth layer of urgency: income-producing assets parked in the wrong account type now carry a steeper tax cost than they did when yields were low. Each of these choices is a timing decision, and the clock on several of them runs out well before age 65.

Editor’s note: This article updates the average Fidelity 401(k) balance for the 60 to 64 age bracket to $257,400 and the 65 to 69 cohort to $258,800, reflecting Fidelity’s Q1 2026 data, and refreshes the 10-year Treasury yield to approximately 4.97% as of mid-September 2026, up sharply from the June 24 figure previously cited. The 2027 Social Security COLA projection of roughly 3.5% to 3.6% has been added as forward-looking context.
