Roger Whitney to 60-Year-Old With $3.5M: ‘Continue to Save in Your Roth 401(k) and Use Your After-Tax Cash’

A 60-year-old caller named Sue wrote into the Retirement Answer Man podcast with a question that might sound mundane but ranks among the most consequential decisions a pre-retiree can make.

She and her husband hold just under $3.5 million across their accounts: $2.1 million pre-tax, $1.3 million taxable, $80,000 in Roth savings, and $300,000 in cash. Sue is still working and plans to retire at 62. Before she does, she wants roughly $100,000 for home projects.

Her instinct, in her own words: “I would like to stop saving for retirement and use the cash for projects around the house. About $100,000 before I retire.” Stop the Roth 401(k) contributions, let the paycheck rebuild the cash account, and pay for the renovations without touching the $300,000 reserve.

Roger Whitney told her to do the opposite. Keep maxing the Roth 401(k). Spend the cash.

The verdict: Whitney is right, and the margin isn’t close

We have been following Roger Whitney’s Retirement Answer Man podcast for several years, and this is the kind of counterintuitive call that separates planners who think in tax buckets from those who simply track account balances. Whitney’s reasoning centers on what financial planners call optionality. Two pools of money can each fund a kitchen remodel, but they are not interchangeable on the back end. Cash in a savings account has no special tax status. Roth 401(k) contribution room, once skipped, vanishes forever. You cannot go back next year and reclaim this year’s contribution space.

Here is how Whitney framed the do-over button: “If you use your $100,000 in after-tax cash and you continue to save in your Roth 401(k), and say 3 years from now you realize, wow, we don’t have as much cash as we needed in our cash reserves, you can always take the money from your Roth.”

And the cost of doing it Sue’s way: “Whereas if you stop saving in your 401(k) in order to preserve your cash, you lose that option on the money that could have been growing tax-free forever.”

Walking through the math

Picture two paths over the next two years until Sue retires at 62.

Path A (Sue’s instinct): Stop contributing. Direct that money into cash. Pay for the home projects from new savings. End state: $300,000 cash mostly intact, Roth 401(k) limited to the contributions Sue made before this year and nothing more. The forgone Roth contributions never get to compound tax-free, ever.

Path B (Whitney’s call): Keep maxing the Roth 401(k). Pull $100,000 from the $300,000 cash pile for the renovations. End state: $200,000 cash remaining, plus two extra years of Roth contributions compounding tax-free for the rest of her life.

For 2026, Sue can contribute up to $35,750 if her plan offers the super catch-up provision for ages 60 to 63 (the $24,500 base limit plus the $11,250 super catch-up). If everything goes to plan and the $200,000 cash cushion is enough, the Roth money never gets touched and grows untaxed indefinitely. If cash gets tight in retirement, Sue is past 59.5, and as long as her Roth 401(k) satisfies the 5-year rule, qualified withdrawals come out tax-free. The Roth is acting as both a retirement account and a backup cash reserve. Cash can only ever be cash.

The variable that changes the answer

The entire calculus rests on whether Sue can actually reach the Roth money without penalty if she needs to. For a 60-year-old, the relevant rules are age 59.5 (already cleared) and the 5-year rule on the Roth 401(k) itself. This year she started maximizing her Roth 401(k) contributions because her Roth accounts are low. If the Roth 401(k) is brand new this year, the clock matters.

Unlike a Roth IRA, each Roth 401(k) has its own 5-year seasoning period. Rolling it to a Roth IRA she has held for more than five years before tapping it is one workaround. Waiting until the account itself crosses the 5-year mark is the other. Once both conditions are met (five years and age 59.5), qualified withdrawals emerge tax-free and penalty-free.

For a saver under 59.5, the math flips. Locking $100,000 into a Roth 401(k) and then needing it for a roof in two years means either a hardship withdrawal, a 401(k) loan, or penalties. Cash wins for that person. For Sue, age has already unlocked the door.

Why 2026 makes this decision even more compelling

Starting January 1, 2026, a new rule from the SECURE 2.0 Act took effect: workers age 50 or older who earned more than $150,000 in the prior year must make all catch-up contributions to a Roth 401(k), not a traditional pre-tax account. If Sue earned above that threshold in 2025, her catch-up dollars are already required to go into the Roth. That means Whitney’s advice aligns perfectly with the tax code’s new direction. The law is effectively telling high earners to build Roth balances, and Sue is in the exact situation where that mandate delivers the most value.

Even if Sue’s income fell below the $150,000 threshold, the optionality argument still holds. But the SECURE 2.0 provision reinforces the idea that Roth contribution room is a perishable, high-value asset, especially for someone two years from retirement with minimal Roth savings.

What to actually do with this

1. List every pot of money you have by tax treatment: pre-tax, Roth, taxable, cash. Sue’s split of $2.1 million pre-tax, $1.3 million taxable, $80,000 Roth, and $300,000 cash tells the story instantly: she is Roth-starved and cash-heavy.
2. Confirm your Roth 401(k)’s start date and your age. If you are past 59.5 and the 5-year clock is running or can be inherited from an older Roth IRA via rollover, the account doubles as an emergency backstop.
3. Before cutting contributions to free up cash, ask whether the cash you already hold can cover the goal. If yes, the contribution room is more valuable than the liquidity buffer you would rebuild.
4. Treat this year’s contribution limit as a perishable asset. Unused room expires at year-end and never comes back. For 2026, that means up to $24,500 in base contributions, plus $8,000 in standard catch-up (ages 50 and up), or $11,250 in super catch-up (ages 60 to 63).

Tax-advantaged contribution room is the rare financial asset with an expiration date. Spending cash you already have is reversible. Skipping a Roth contribution year locks that opportunity away forever.
