What $10K a Month Really Looks Like in Retirement at Age 67 With a $2.4M Portfolio

The $10,000 a month retirement sounds great. A 67-year-old couple with $2.4 million and Social Security already claimed assumes the math works. But there’s sometimes a gap between their retirement dreams and reality.

Picture a married couple, both 67, filing jointly. They have $1.5 million in a traditional IRA, $400,000 in a Roth IRA, and $500,000 in a taxable brokerage account with a $300,000 cost basis. Combined Social Security benefits claimed at full retirement age come to $48,000 a year. They want $10,000 a month to cover the mortgage or rent, groceries, travel, and gifts to the grandkids.

This scenario shows up constantly on r/retirement and r/financialindependence forums. A couple in their late 60s with mid-seven-figure savings wonder whether they can “just take $120,000 a year and call it good.”

At 67, a couple should plan for a horizon stretching to age 95. Sequence-of-returns risk in the first five years drives more retirement failures than any other variable. And inflation is not done with retirees. Core PCE has climbed from 125.79 in May 2025 to 129.28 in March 2026, still running above the Fed’s 2% target.

Walking the Math Down to the Net

To put $10,000 in the bank each month, the couple must cover federal tax, state tax, and Medicare-related healthcare. Social Security delivers $48,000, of which 85% ($40,800) is taxable at this income level.

Assume the couple pulls roughly $135,000 from the traditional IRA. Add the taxable portion of Social Security and ordinary income lands near $175,800. The 2026 married-filing-jointly standard deduction is $32,200, leaving taxable income around $143,500. Run that through the 2026 brackets (10% to $24,800, 12% to $100,800, 22% to $211,400) and federal tax comes to about $21,200. Layer on roughly $7,200 of state tax at a 5% average rate, then $10,000 to $12,000 a year in out-of-pocket healthcare above Medicare premiums.

What lands in the checking account: about $95,600, or $7,970 a month. So the $2.4 million portfolio, run through an all-traditional-IRA withdrawal, delivers roughly $8,000 a month of real spending, not $10,000.

To actually net $10,000, the couple must gross closer to $155,000 to $160,000 a year from accounts. That pushes the withdrawal rate from a defensible 5% to an uncomfortable 6.5%. Bill Bengen’s original 1994 work pegged the sustainable starting rate at roughly 4%, and modern updates rarely stretch past 5% for a couple still in their 60s.

Three Paths That Could Close the Gap

All is not lost. The couple has real levers worth considering:

1. Blend the account types to cut the tax bill. Instead of pulling everything from the traditional IRA, draw proportionally from the Roth (tax-free) and the brokerage (mostly return of basis, with gains taxed at long-term rates). On a $500,000 brokerage with $300,000 basis, 60% of every dollar withdrawn is already your money back. This can cut the gross withdrawal needed to net $10,000 by $15,000 to $20,000 a year.
2. Harvest brokerage gains in the 0% long-term capital gains bracket. For 2026, MFJ couples pay 0% on long-term gains up to roughly $96,700 of taxable income. Realizing gains opportunistically in low-income years resets cost basis without a tax bill and reduces future drag.
3. Bridge with part-time work from 67 to 72. Even $30,000 a year of consulting income covers most of the gap, lets the portfolio compound, and shortens the withdrawal horizon by five years. With the 10-year Treasury near 4.5%, locking part of the bond allocation into a ladder also reduces sequence risk.

The fourth path, often the right one, is to re-target lifestyle spending at $8,000 a month. That number is what the portfolio actually supports and preserves the safe-withdrawal headroom that makes the plan durable to age 95.

What to Do First

Run the tax projection before deciding the withdrawal mix. The single most expensive mistake is defaulting to “IRA first” out of habit, which front-loads ordinary income, pushes the couple toward the MFJ IRMAA tier near $218,000, and wastes the Roth’s lifetime tax shield. A fee-only advisor earns their keep on this decision because the multi-year tax projection across three account types is complex.

Write down the $10,000 number and the $8,000 number side by side, and decide which one you are planning around. The couple that picks $8,000 at 67 likely ends up with more flexibility at 80 than the couple that insists on $10,000 and discovers the gap a decade too late.
