Ramsey argues that switching to a traditional 401(k) saves taxes on $600,000 in contributions while forcing taxes on $2.5 million in growth, which he calculates to be a roughly $750,000 mistake. <\/p>\n<\/li>\n
Under the SECURE Act, heirs must drain an inherited traditional IRA within 10 years, potentially forcing $300,000 in annual taxable distributions on top of their income. <\/p>\n<\/li>\n
A traditional 401(k) only wins if your retirement tax rate is dramatically lower than today’s. That outcome seems unlikely given rising deficits and persistent inflation. <\/p>\n<\/li>\n
Two retirees, same $1 million, same 4% rule, buy one finished with $1.4 million, the other hit $0 in 12 years. Our free reader guide<\/a> explains the flaw that separated them, and the income-first method built to avoid it. <\/p>\n<\/li>\n<\/ul>\n A 40-year-old caller phoned into The Ramsey Show with a nagging feeling. Her financial advisor had told her to stop funding her company’s Roth 401(k) and redirect the money into a traditional 401(k) instead, pointing to her income level and the immediate tax deduction. She planned to max out at $24,000 a year either way. She guessed something was off but didn’t know if there was a specific circumstance where the switch would be beneficial. <\/p>\n Dave Ramsey did not hedge. “You need to get a new financial advisor that can actually do math,” he told her, then added, “I’m flabbergasted that somebody could be this dumb and call themselves a financial advisor.” <\/p>\n The Verdict: Ramsey Is Right on the Math <\/p>\n For a 40-year-old with a 25-year runway and the cash flow to max contributions, the Roth almost always wins. The reason is simple: the tax deduction on a traditional 401(k) applies only to the money you put in. Every dollar of growth on top of that comes out taxable in retirement. A Roth flips that equation. You pay tax on the seed. The harvest is yours. <\/p>\n The 4% Rule is Broken, Built On A World That No Longer Exists<\/strong> <\/p>\n Every retiree knows about the 4% rule, but it frames retirement as a slow liquidation and still causes retirees with seven-figure accounts to agonize over a dinner out. <\/p>\n There’s a different way to run the math that makes more sense today. Build an income floor \u2014 dividends, interest, and Social Security that cover your essential bills every month \u2014 and you never have to sell shares into a down market just to pay them. <\/p>\n Our free reader guide, The 4% Rule Is Broken<\/strong><\/a>, walks through it in about 15 minutes. Access the report here.<\/a> <\/p>\n Ramsey walked through the numbers live. $24,000 a year over 25 years produces a projected $3.1 million by age 65. Total contributions come to roughly $600,000. The remaining $2.5 million is pure growth. That distinction is the entire ballgame. <\/p>\n Story Continues <\/p>\n Here is how he framed the trade the advisor was pitching: “He’s telling you to save taxes on $600,000 of the $3.1 million, but for doing that, you get to pay taxes on $2.5 million.” Ramsey pegged the tax exposure on that growth at $700,000 to $800,000 and called it almost a million-dollar mistake. “A guy that makes a million-dollar mistake, you don’t keep,” he said. <\/p>\n The inflation backdrop makes the case sharper, not softer. The Consumer Price Index sat at 332.6 in June 2026, and core PCE has climbed steadily from 126.43 in July 2025 to 130.08 in May 2026. Persistent inflation tends to push tax brackets and future tax rates higher, which is precisely the environment where locking in today’s rate through a Roth pays off. <\/p>\n Run your own numbers and you will see the same pattern Ramsey drew on air. The larger the growth relative to contributions, the worse the traditional account looks by comparison. <\/p>\n The Inheritance Trap Nobody Talks About <\/p>\n The tax bill does not stop at retirement. Ramsey flagged the inheritance angle, which is where the traditional account gets even uglier. Under the Secure Act, heirs must fully draw down an inherited traditional IRA within 10 years. On a $3.1 million balance, that means roughly $300,000 a year of forced taxable distributions stacked on top of whatever your kids already earn. That likely pushes them into a top bracket for a decade. <\/p>\n A Roth inheritance carries the same 10-year drawdown rule but no income tax on the distributions. “It’s harder in retirement, it’s harder in inherited, and you pay light-years more taxes. There’s no case where this is not going to happen,” Ramsey said. <\/p>\n The Variable That Could Flip the Math <\/p>\n The one factor that could actually tilt this in favor of traditional is a genuine belief that your retirement tax rate will be dramatically lower than your working rate. That is a bold call. The federal funds rate has come down from 4.5% a year ago to 3.75%, but rate paths and tax policy are different animals. Federal deficits, entitlement funding, and the 2.8% Social Security COLA for 2026 all point toward pressure for higher revenue collection over a 25-year horizon, not lower. <\/p>\n If you retire with a $3 million balance plus Social Security plus required minimum distributions, your effective bracket in retirement can easily match or exceed your bracket today. That is the scenario Ramsey’s math assumes, and it is the realistic one for someone maxing contributions for 25 years. <\/p>\n What to Do This Week <\/p>\n Log into your 401(k) portal and confirm whether your plan offers a Roth option. Many do and employees never enable it. <\/p>\n<\/li>\n Model both paths using an IRA comparison calculator with your actual salary, contribution, and expected return. Pay attention to the after-tax balance at 65, not the gross number. <\/p>\n<\/li>\n Ask your advisor to show the math in writing, including the tax on projected growth and the Secure Act drawdown impact on heirs. If they cannot, get a second opinion. <\/p>\n<\/li>\n Remember that employer matching contributions always go into a traditional (pre-tax) bucket, so you get some tax diversification automatically. <\/p>\n<\/li>\n<\/ol>\n Individual situations vary and a qualified tax professional should review your specifics, but the principle Ramsey hammered on is durable: when the growth dwarfs the contributions, you want the growth to come out tax-free. <\/p>\n Before Your Next Withdrawal, Run One Number ( It’s Not The 4% Rule Everyone Knows) <\/p>\n Take your essential monthly expenses and subtract your guaranteed income \u2014 Social Security, plus any pension. What’s left is your income gap, and how you close it determines whether retirement runs on share sales or on a paycheck your portfolio writes you every month. Our free reader guide, The 4% Rule Is Broken<\/a>, shows exactly how to close that gap with portfolio income: a worked example (one retiree needed about $480,000 in income-producing assets to cover his essentials for good), an eight-point conversion checklist, and the 20-year numbers comparing dividends to withdrawals. It’s free and takes about 15 minutes to read. Get the guide here<\/a> before you take your next withdrawal. <\/p>\n<\/a> Rick Diamond\/Getty Images) <\/p>\n
