Dave Ramsey Has a One Word Strategy for Big Roth Conversions and It Quietly Saves Retirees Six Figures in Lifetime Tax

Dave Ramsey spent time on his show walking a caller through one of the most overlooked moves in retirement tax planning: converting a traditional IRA to a Roth in small annual slices instead of one giant taxable event. Done carelessly, the difference can cost six figures in lifetime taxes that never needed to be paid.
Here is what Ramsey said, verbatim:
“It’s tempting to move the money that you have in traditional gradually to Roth to keep you from having bracket creep… you could run those numbers out… you could run like bump a couple of brackets but not go all the way to 40, not go all the way to 39. Right. That’s one way of doing it. And do a little bit a year and kind of dribble it out.”
The verdict: Ramsey is right, and the math is brutal if you ignore him
Dribbling beats dumping, and the reason is built into the tax code itself. The U.S. income tax system is progressive, so every additional dollar of conversion income stacks on top of your existing income and gets taxed at the next rate up. Convert a $1.2 million IRA in a single year and you pay top marginal rates on most of it. Spread $100,000 a year across twelve years and you stay in the cheaper brackets throughout.
The bracket structure is what does the damage. For 2026, married filing jointly, the 12% bracket runs to $100,800, the 22% bracket to $211,400, the 24% bracket to $403,550, the 32% bracket to $512,450, and the 35% bracket extends to $768,700, where the top rate of 37% begins. The standard deduction for MFJ filers is $32,200. Retirees 65 and older also qualify for the temporary OBBBA Senior Bonus Deduction, worth $6,000 per qualifying individual, or up to $12,000 combined for a couple where both spouses are 65 or older. This extra deduction is available through 2028 for couples with modified adjusted gross income at or below $150,000. That cushion can push more of each year’s conversion into the lower brackets.
A real scenario with real dollars
Take a couple, both 65, with $1.5 million in traditional IRAs. For context, that is roughly five times the average baby boomer IRA balance of $286,700, according to Fidelity’s analysis of 19.6 million IRA accounts as of Q1 2026. It is a realistic target for a diligent, above-average saver. They draw $80,000 a year combined from Social Security and a small pension. After the standard deduction and the senior bonus deduction, taxable income sits near $42,000, comfortably inside the 12% bracket.
Option one: the dump. Convert the whole $1.5 million in one year. Stacked on top of existing income, that conversion blows through the 22%, 24%, 32%, and 35% brackets and parks the top slice at 37%. Federal tax on the conversion alone lands around $475,000 to $500,000, plus state tax and a guaranteed IRMAA Medicare premium surcharge.
Option two: the dribble. Convert roughly $150,000 a year for ten years. Each year, the conversion fills the rest of the 12% bracket and most of the 22% bracket, with a small slice taxed at 24%. The blended federal rate on each year’s conversion lands around 18% to 20%. Over a decade, total federal tax on the same $1.5 million comes in around $290,000 to $310,000.
The savings: roughly $175,000 in federal tax kept out of the IRS’s hands. The Roth balance then grows tax-free for the rest of their lives, and heirs inherit a ten-year distribution window with no ordinary income tax owed on the gains.
The variable that flips the answer
The whole strategy hinges on one number: your marginal tax rate in your 70s versus today. If you expect to be in a lower bracket once required minimum distributions and Social Security stack up, conversions will cost more than they save. A higher bracket awaiting you in retirement makes them worth doing.
Required minimum distributions start at age 73. On a $1.5 million traditional balance that has compounded through your 60s, the first-year RMD lands near $60,000 and climbs each year after that. Add Social Security, a pension, and any portfolio income, and a couple sitting comfortably in the 12% bracket at 65 can easily find themselves in the 24% or 32% bracket at 75. That is the bracket creep Ramsey is warning about.
The broader trend shows more retirees are running this math. Fidelity’s Q1 2026 retirement analysis, drawn from 19.6 million IRA accounts, found that Roth conversion transactions rose 41% year over year, while 67% of all IRA contributions went to Roth accounts in the quarter. Both figures set records. Savers have reached the same conclusion Ramsey laid out on his show.
The rate environment has added urgency. The Federal Reserve raised the federal funds rate by a quarter point to 3.75%-4.00% at its September 15-16, 2026 meeting, its first rate hike since 2023, responding to inflation that remained above the central bank’s 2% target. The 10-year Treasury yield climbed further in October, reaching 5.37% on October 7, a 24-year high not seen since 2002, before pulling back to around 5% by late October. Every dollar moved to a Roth today compounds tax-free against that elevated rate backdrop, which strengthens the long-run case for converting sooner rather than later.
What to do this week
- Pull last year’s tax return and identify your current marginal federal bracket. Note how much room you have before the next bracket kicks in.
- Project your RMD-era income. Estimate your traditional balance at 73, multiply by roughly 4% for the first RMD, and add Social Security and any pension.
- Pick a target ceiling. Ramsey’s framing of bumping a bracket or two without touching 32%, 35%, or 37% is the right instinct for most retirees.
- Watch the IRMAA cliffs. Medicare premium surcharges trigger at specific MAGI thresholds and can add thousands per year if a conversion pushes you over.
- Coordinate with Social Security timing. Conversions before claiming benefits avoid making more of those benefits taxable.
Ramsey’s word for it was dribble. Picture a steady faucet, open just wide enough to fill the cheap brackets each year without spilling into the expensive ones. That is the mechanism that keeps the IRS out of the top of your stack.
Editor’s note: This pass corrected the OBBBA Senior Bonus Deduction figure from “$6,000” for the couple to its accurate amount of $6,000 per qualifying individual ($12,000 combined for a couple where both spouses are 65 or older), and updated the Federal Reserve and Treasury yield section to reflect the Fed’s completed September 2026 rate hike to 3.75%-4.00% and the 10-year Treasury yield’s October 2026 peak of 5.37%, its highest level since 2002.
