Can You Retire with $4 Million?

The withdrawal rate math at $4 million

The foundational question for any retirement analysis is the sustainable withdrawal rate — how much you can draw from a portfolio each year, adjusted for inflation, without running out of money over a long horizon. William Bengen's 1994 research (the "4% rule") and the subsequent Trinity Study established the broadly accepted framework: at 4%, a well-diversified portfolio has a high historical success rate over 30 years.⁵

At $4 million, the raw withdrawal math:

Two important refinements. First, the 4% rule was calibrated for 30-year retirements. Retire at 57 and plan to 95 and you're looking at a 38-year horizon — the historically safe rate for that window is closer to 3.5–3.7%. Second, Social Security fundamentally changes this picture. A couple with a combined $60,000–$80,000 in annual Social Security benefits needs the portfolio to cover only the remaining gap. At $145,000 in spending and $70,000 from Social Security, the portfolio draw is just $75,000 — a 1.9% effective rate, far below the danger zone.

The income stack: what $4M retirement actually looks like

Few retirees draw exclusively from their portfolio. A realistic $4M retirement income picture is a layered stack where Social Security and other income reduce the portfolio draw to a much lower effective rate:

Social Security timing at $4M — still high leverage

At $3M, Social Security timing is the most consequential financial decision you'll make. At $4M, the portfolio gives you more cushion — but the math is still compelling enough to take seriously.

For a couple where the higher earner had above-average lifetime earnings, the difference between claiming at 62 versus 70 can be $20,000–$30,000 per year, inflation-indexed for life. The 2026 maximum monthly benefit at age 70 is $5,181.¹ At FRA (age 67 for those born 1960 or later), the maximum is $4,152. Claiming at 62 reduces FRA benefits by up to 30%.

The break-even for delaying from FRA to 70 is roughly age 82–83. For a healthy couple in their early 60s, the probability that at least one spouse survives to 83 is well above 50%, and the survivor benefit — paid to the surviving spouse based on the higher earner's benefit — makes the delay even more valuable. The higher earner's delayed benefit is not just income for two; it becomes the surviving spouse's lifelong income source.

The pre-Medicare healthcare bridge at $4M

Healthcare before age 65 is the most frequently underestimated retirement expense, and $4M doesn't make it go away — it just makes it more manageable. Realistic costs for a couple in their early 60s:

• ACA marketplace premiums (unsubsidized), ages 60–64: $1,200–$2,200/month per couple, depending on state and plan tier
• Annual all-in (premiums + typical deductibles/copays): $20,000–$35,000/year per couple

At $4M, a $28,000/year healthcare budget represents about 17–19% of a $145,000–$160,000 spending plan — meaningful, but not plan-breaking the way it can be at $3M. The planning opportunity: keeping modified adjusted gross income (MAGI) below 400% of the Federal Poverty Level for a couple (roughly $84,600 in 2026) preserves access to premium tax credits that can cut the ACA bill by $10,000–$18,000/year.⁶ At $4M with the right account draw sequence — primarily Roth and low-basis taxable positions — this is achievable during the early retirement years.

The Roth conversion window at $4M

For many families at the $4M level, the single highest-leverage planning opportunity is aggressive Roth conversions between retirement and age 73–75 (when RMDs begin). If a meaningful portion of the $4M is in traditional IRAs or 401(k)s, converting systematically over 8–13 years accomplishes three things simultaneously:

1. Locks in today's tax rates before RMDs potentially push you into higher brackets at 73–75
2. Eliminates or reduces future IRMAA surcharges — Medicare Part B starts at $202.90/month base in 2026 but adds surcharges starting at $212,000 MAGI for married couples³
3. Reduces inherited IRA tax burden — your heirs must draw down inherited traditional IRAs over 10 years at ordinary income rates; Roth conversion eliminates that tax on the conversion amount

At $4M, the Roth conversion math is particularly attractive: the 2026 MFJ 22% bracket runs from approximately $96,950 to $201,050.³ A couple with $60,000 in combined Social Security (85% taxable = $51,000) and $30,000 in basic IRA draws has about $120,000 in remaining 22% bracket headroom — enough to convert $80,000–$100,000 per year at 22–24% when the tax math is favorable. Converting at 22–24% now avoids 32–37% ordinary income rates on large RMDs later.

LTC self-insurance at $4M

Long-term care is one of the primary financial risks in retirement — a nursing facility in a mid-cost state averages $7,000–$10,000/month ($84,000–$120,000/year). A 3-year LTC event could cost $250,000–$360,000.

At $4M, self-insurance becomes a viable option in a way it isn't at $3M. With $4M in assets and a 3-year LTC event costing at most $360,000, you're drawing down about 9% of the portfolio — painful but not plan-ending. The key planning questions:

• What's the likely split between spouses? One healthy spouse continuing for 20+ years while the other is in memory care for 3–5 years is the high-risk scenario. At $4M for a couple, a 5-year LTC event at $150,000/year ($750,000 total) would reduce the surviving spouse's portfolio from $4M to roughly $3.25M (net of the LTC draw, not accounting for investment growth) — still viable but meaningfully tighter.
• Hybrid life/LTC policies purchased in your 50s are still worth considering at the $4M level — not because you can't absorb the cost, but because they convert uncertain, open-ended LTC risk into a defined premium and benefit structure.

The tax picture in retirement at $4M

With a diversified account mix — traditional IRA, Roth, and taxable — the federal tax picture for a $4M household in retirement is often surprisingly efficient. An example for a couple (both 67+) spending $145,000/year:

• Social Security: $65,000/year combined (85% taxable above $44K provisional income threshold = $55,250 taxable)
• Traditional IRA draw: $45,000
• Taxable account (qualified dividends + LTCG): $35,000
• Ordinary income before deduction: $55,250 + $45,000 = $100,250; minus 2026 MFJ standard deduction $32,200³ = $68,050 taxable ordinary income
• Tax on $68,050 (MFJ 2026): ~$7,700
• LTCG tax on $35,000: $30,850 at 0% (room remaining before $98,900 LTCG ceiling); $4,150 at 15% = ~$623⁴
• Total federal tax: approximately $8,300 on $145,000 gross income
• Effective federal rate: ~5.7%

Compare: the same $145,000 drawn entirely from a traditional IRA would face $145,000 minus $32,200 standard deduction = $112,800 taxable ordinary income — approximately $18,500 in federal tax, an effective rate of 12.8%. The difference — $10,200/year — compounds over 20 years to more than $200,000 in unnecessary taxes. Account draw sequence is the single most tax-efficient lever available in retirement.

What can derail a $4M retirement

The primary failure modes at this wealth level are not "ran out of money from normal spending" — they're scenarios that break the underlying assumptions:

1. Sequence of returns in early retirement. A 35–40% bear market in years 1–4 — before Social Security begins and before the portfolio has grown — permanently impairs spending capacity. At $4M drawing $160K/year, a 35% decline leaves $2.6M generating $104K at 4% — a meaningful step down. Mitigation: a 2–3 year cash/short-term-bond reserve equal to net spending needs ($65,000–$100,000 for most households at this level) prevents forced equity selling at the bottom.
2. Uncapped healthcare inflation. Healthcare costs historically rise 2–4 percentage points above general CPI. A couple spending $28,000/year on healthcare at 5% annual healthcare inflation faces $45,000/year in 10 years — a $17,000 annual increase. Budget conservatively, or use Roth conversion strategy to stay ACA-eligible longer.
3. The IRMAA trap from skipped Roth conversions. Without Roth conversions in the 60s, RMDs starting at age 73–75 push MAGI above $212,000 (MFJ), triggering IRMAA surcharges that cost $5,000–$20,000 per year per couple, permanently, for the rest of your lives.³ At $4M concentrated in traditional IRAs, skipping the conversion window can cost $150,000+ in cumulative surcharges.
4. State income and estate taxes. At $4M, the federal $15M OBBBA estate exemption per person means federal estate tax is not a near-term concern. But a dozen states have estate exemptions as low as $1M–$4M (Oregon $1M, Massachusetts $2M, Washington $3.1M, Minnesota $3M, Illinois $4M). A couple with $4M living in Massachusetts, for example, faces a real state estate tax unless they use simple planning: portability election (a key step that must be taken on the first spouse's estate return), asset titling, or a marital deduction trust. State income taxes are also a material factor — see our state income tax planning guide.
5. Advisor fee drag over time. At $4M and 1% AUM, you're paying $40,000/year — $800,000 over 20 years in nominal terms, plus the compounded return on that money. This isn't necessarily a poor investment (a good advisor earns far more than this in tax alpha alone), but it's a material number worth scrutinizing. A flat annual retainer or hourly fee-only model often makes more economic sense at this wealth level than percentage-of-AUM pricing. See our fee-only vs. AUM comparison guide.
