Can I Retire with $8 Million?

Yes — $8 million is well past the threshold where running out of money is the primary concern. The planning questions shift: How do you prevent large RMDs from locking you into IRMAA Tier 3 or 4 permanently? How much Roth conversion window do you have left? What does your state's estate tax exposure look like at this level? And are you capturing the investment access that comes with crossing the Qualified Purchaser threshold? Here's what retirement actually looks like at $8M — with an interactive calculator to model your specific situation.

The short answer: depletion risk is negligible, tax drag is the main variable

A $8 million portfolio at a 3.5% sustainable withdrawal rate supports $280,000 per year in inflation-adjusted spending for 35+ years. At 4%, it's $320,000 per year — before Social Security and other income sources are added. For almost any realistic retirement scenario, $8 million does not run out.

The planning challenge at this level isn't survival — it's optimization. The same $8 million household can pay $40,000 or $100,000+ per year in federal and Medicare taxes depending on account structure, income sequencing, Roth conversion decisions, and Medicare management. That variance — often $50,000–$70,000 per year — is the reason specialized planning at $8M pays for itself many times over.

Withdrawal rate	Annual income from portfolio	Monthly income	35-yr success rate (historical)
3.0%	$240,000	$20,000	~99%
3.5%	$280,000	$23,333	~98%
4.0%	$320,000	$26,667	~96%
4.5%	$360,000	$30,000	~90%

Historical success rates based on U.S. equity/bond market data (Bengen 1994, Trinity Study). A 35-year horizon (e.g., retiring at 60, planning to 95) supports slightly lower withdrawal rates than the 30-year studies. Social Security income, which is not included above, dramatically reduces the effective portfolio withdrawal rate.⁵

The income stack: what $8M retirement actually looks like

A realistic $8M retirement isn't "withdraw $320,000/year from one account." Income typically comes from a layered stack where the portfolio fills the gap between fixed income and total spending:

Income source	Annual amount (couple, typical)	Notes
Social Security — both spouses at 70	$80,000–$124,000	Max 2026: $5,181/mo per person at age 70; inflation-adjusted for life¹
Portfolio withdrawals (pre-RMD)	$120,000–$200,000	Drawn from taxable first, then IRAs — sequenced to minimize IRMAA exposure
Required minimum distributions (age 75+)	$165,000–$310,000	Depends almost entirely on how much was converted to Roth before RMD age
Roth withdrawals	$0–$60,000	Tax-free and excluded from IRMAA MAGI — the most valuable income source in retirement

The wide range on required minimum distributions — "$165,000–$310,000" — is almost entirely determined by Roth conversion activity in the decade before RMDs began. A couple who did nothing with a $4.5M traditional IRA sees that IRA grow to approximately $7.5M by age 75 (at 5% growth over 13 years from age 62). The first RMD: $7.5M ÷ 27.4 (Uniform Lifetime Table, age 75) = $274,000 in year 1. A couple who converted systematically arrives at 75 with a $4M–$4.5M IRA and an RMD of $146,000–$164,000. That $110,000–$128,000 difference in annual income triggers different IRMAA tiers, different marginal tax rates, and different lifetime tax outcomes — measured in the hundreds of thousands of dollars.

The $8M IRA math. Under SECURE 2.0, those born in 1960 or later face RMDs starting at age 75.² If you retire at 62 with $4.5M in a traditional IRA and take no action, that $4.5M grows to approximately $7.5M by 75 at 5% (13 years). Your first RMD = $7.5M ÷ 27.4 = $274,000 in year 1. Combined with Social Security and investment income, this routinely puts couples into IRMAA Tier 3 or 4 permanently — paying $12,000–$15,000/year more in Medicare premiums than a household that converted strategically.

IRMAA at $8M: the Medicare premium tax that compounds

Medicare Part B base premium in 2026 is $202.90/month per person ($4,870/year for a couple).³ But once your MAGI exceeds the first IRMAA threshold as a married couple, surcharges add $81 to $487 per person per month on top of that. At $8M, the no-conversion scenario routinely lands in Tier 3 or higher — every year for the rest of retirement.

Here's the concrete MAGI math for an $8M household at age 76 (no prior Roth conversions, 50% of portfolio in traditional IRA):

MAGI estimate, age 76 — couple with $8M at retirement (50% traditional IRA, no Roth conversions done)
Income source	Amount	MAGI treatment
RMD from $8.1M IRA at age 76 (ULT 26.5)	$306,000	100% ordinary income
Social Security (combined, delayed to 70)	$95,000	85% includable = $80,750
Taxable account income (dividends/interest)	$45,000	Fully included; muni bond interest also counts
Total MAGI	~$432,000	IRMAA Tier 4 ($400K–$500K) — $607/mo per person Part B

At IRMAA Tier 4, the couple pays $607.00/month per person for Part B — $14,568/year combined — versus $4,870 at the standard rate. That's $9,698/year in excess Medicare premiums, every year for the rest of retirement. Plus Part D surcharges of roughly $1,200/year combined. Over 15 years: approximately $163,000 in avoidable Medicare premium costs — from a household that, with planning, didn't need to be in Tier 4 at all.

With systematic Roth conversions ($150K/year for 10 years): The same couple arrives at 76 with a $4.3M IRA (instead of $8.1M). Their RMD is approximately $162,000 instead of $306,000. MAGI: ~$288,000 → IRMAA Tier 2 ($268K–$334K), paying $405.80/mo per person = $9,739/year combined. Annual Medicare savings vs. no-conversion scenario: ~$4,800/year. Over 15 years of retirement: ~$72,000 in Medicare premium savings — not counting the income tax savings on lower RMDs, which are typically 3–5× larger.

The income tax savings from converting at 22–24% during the Roth conversion window versus paying 32–37% on large RMDs later is typically the dominant benefit — not the Medicare premium reduction alone. Both effects compound in the same direction. See our Roth conversion strategy guide for the full tax-bracket math, and our IRMAA planning guide for the complete 2026 tier table and calculator.

The Roth conversion window at $8M

The window is the years between retirement and when RMDs begin — typically ages 60–73 or 60–75 depending on birth year. For $8M households, this is the single highest-value planning period in the entire retirement arc, because it's the only window where you have near-total control over taxable income.

During the window: Social Security hasn't started (or you're delaying it). RMDs haven't started. You draw down taxable accounts and convert IRAs at a rate you choose. For a couple with a $32,200 standard deduction, the 22% federal bracket runs to $201,050 of taxable income and the 24% bracket runs to $383,900 in 2026.⁴ Converting $150,000/year from a traditional IRA costs approximately $36,000 in federal tax — converting at a rate almost certainly below what future RMDs would force you to pay at 37%.

Example: couple retires at 62, $4.5M traditional IRA, delays SS to 70, converts $130K/yr during window
Age	Traditional IRA balance	Action	MAGI
62	$4,500,000	Convert $130K, draw $70K from taxable	~$200K — just below IRMAA first tier
70	$4,300,000	Start SS ($95K/yr); reduce conversion to $80K	~$248K — IRMAA Tier 1; manage carefully
75	$4,100,000	RMDs begin ($150K/yr); reduce conversions	~$311K — IRMAA Tier 2
80	$3,700,000	RMDs $162K/yr (ULT 22.9); stop converting	~$323K — still Tier 2, not advancing to Tier 3

Compare the no-conversion scenario (IRA grows from $4.5M to $8M+ by 80, with $350K+/year RMDs and IRMAA Tier 4) against the active conversion scenario above (Tier 2 throughout retirement, RMDs manageable). The total lifetime tax and Medicare premium difference can exceed $500,000–$700,000 — from the same $8M portfolio.

Social Security timing at $8M

Delaying Social Security from FRA (67 for those born 1960+) to 70 provides an 8% annual credit — a government-guaranteed, inflation-adjusted annuity. The maximum 2026 benefit at 70 is $5,181/month per person.¹ At FRA, it's $4,152/month. For a couple where both spouses maximized earnings, delaying both to 70 generates up to $124,344/year in SS income — inflation-adjusted for life.

At $8M you can easily self-fund the years between early retirement and 70. The break-even on delaying from FRA (67) to 70 is approximately age 82. The survivor benefit argument is compelling: the higher earner's maximized benefit ($5,181/month) becomes the surviving spouse's permanent benefit. The Roth conversion interaction: the years from retirement to 70 are your highest-value conversion window — no SS income means lower MAGI and more room in the 22–24% brackets. Starting SS earlier compresses that window and raises MAGI. For most $8M households, the optimal choice is: delay SS to 70, convert aggressively during the low-income years, and use taxable accounts to fund spending in the interim.

State estate tax exposure at $8 million

The federal estate and gift tax exemption is permanently $15 million per person ($30 million for a married couple) under the OBBBA.⁶ An $8M household owes nothing federally. But 12 states plus D.C. have their own estate taxes — and at $8M the exposure becomes significant:

State	Exemption (per person)	Top rate	Approximate state estate tax on $8M estate
Oregon	$1,000,000	16%	~$960,000–$1,120,000
Massachusetts	$2,000,000	16%	~$800,000–$960,000
Minnesota	$3,000,000	16%	~$640,000–$800,000
Washington	$3,193,000	20%	~$720,000–$960,000
Illinois	$4,000,000	16%	~$480,000–$640,000
Connecticut, Maine, Vermont	$5,100K–$7,000K range	12%	$0–$360,000 depending on exact exemption
Florida, Texas, Nevada, WY, SD	No state estate tax	N/A	$0

For a couple living in Oregon or Massachusetts, the second-to-die estate tax bill on $8M could exceed $1 million — on an estate that owes nothing federally. The unlimited marital deduction defers — but does not eliminate — the state estate tax. Planning tools:

Annual gifting: $19,000/donor/recipient in 2026.⁴ A couple can give away $38,000/year to each child, grandchild, or other recipient — outside the taxable estate.
529 superfunding: $95,000/donor ($190,000/couple) per beneficiary via the § 529(c)(2)(B) 5-year election. Removes assets from the estate immediately.
Irrevocable trust strategies: GRATs, SLATs, QPRTs — transfer future appreciation out of the estate at today's value using the § 7520 rate. See our trust strategies guide for the mechanics and interactive GRAT calculator.
State-specific credit shelter trusts: In states with per-person exemptions, a bypass trust on the first death preserves the first spouse's state exemption. Without it, the exemption may be wasted when assets pass directly to the surviving spouse through the marital deduction.
Domicile change: Establishing residence in a no-estate-tax state (Florida, Texas, Nevada) eliminates state estate tax — but requires genuine relocation. High-audit-risk states (MA, NY, CA) scrutinize purported domicile changes aggressively. See our state income tax planning guide for the exit checklist.

The Qualified Purchaser advantage at $8M

At $8 million total wealth, you almost certainly hold well above $5 million in investments — crossing the Qualified Purchaser threshold under the Investment Company Act (§ 2(a)(51)). This is a meaningful investment access change:

3(c)(7) funds: The institutional alternative fund universe — larger private equity funds, private credit managers, hedge funds that only accept QPs — becomes accessible at this tier. 3(c)(1) accredited-investor funds (available at $1M+ net worth) typically have size limits that force them into less competitive strategies; 3(c)(7) funds do not.
Institutional terms: Larger minimum commitments ($500K–$5M per fund) but correspondingly better terms: lower management fees, more favorable carried interest structures, co-investment rights.
Private credit access: Direct lending and specialty finance funds targeting 9–12% net returns (in a normalized rate environment) are commonly available only to QPs. BDCs and interval funds available to accredited investors typically carry additional fee layers.
Caution: QP access does not guarantee superior returns — it removes one barrier. Illiquidity (7–12 year lockups), J-curve drag, and manager selection risk all apply. An alternative allocation of 10–20% is common at this wealth tier, not 50%+. See our alternative investments guide for sizing and access mechanics.

Healthcare before Medicare at $8M

If you retire before 65, healthcare is one of the largest budget line items. A couple in their late 50s on the ACA market — not eligible for employer coverage, not yet on Medicare — typically pays $22,000–$40,000/year for a comprehensive plan. At $8M with portfolio income of $200K+, you're well above the ACA subsidy cutoff and will pay the full unsubsidized premium.

The COBRA bridge (up to 18 months after leaving an employer) often offers better coverage than the individual market at similar cost. After COBRA expires, ACA marketplace plans vary by state and age. Budget $2,000–$3,500/month for a couple approaching 65 — and model this as a fixed cost until Medicare enrollment eliminates it. The IRMAA lookback adds one more wrinkle: your final working year's income (likely high) will be used to set Medicare premiums for your first two years on Medicare. Factor in the SSA-44 new-retiree exception if income drops sharply at retirement.

The fee math at $8 million

A 1% AUM fee on $8 million is $80,000 per year. Compounded over 20 years at a 7% gross return, that 1% fee drag reduces your ending portfolio by approximately $3.5 million — money that would otherwise compound tax-efficiently in your heirs' hands or fund additional retirement spending.

Fee structure	Year 1 cost on $8M	20-yr opportunity cost (7% gross)
1.0% AUM	$80,000	~$3.5M in foregone growth
0.5% AUM (tiered RIA)	$40,000	~$1.6M in foregone growth
Flat retainer, fee-only (NAPFA)	$12,000–$25,000	~$0.4M–$0.8M in foregone growth

At $8M, the difference between a 1% AUM structure and a flat retainer fee-only advisor — purely in fee drag — can fund several years of additional retirement spending. The conflict-of-interest problem with AUM pricing at this level is acute: your advisor earns $80,000/year whether they provide significant value that year or not, and has an incentive to discourage tax-efficient distributions (which reduce AUM) and insurance purchases (which move assets off-platform). See our fee-only vs. 1% AUM comparison for the full math.

Direct indexing and tax management at $8M

With $8M total wealth, a taxable brokerage allocation of $3M–$4M is common. At this scale, direct indexing — owning the individual stocks within an index rather than the ETF — runs at full institutional effectiveness:

Multiple sleeves simultaneously: $3M+ in taxable can run two or three direct index sleeves ($1M+ each), each harvesting losses independently even within a bull market — individual stocks within any index are losing on any given day.
Annual tax alpha: Systematic direct indexing at this scale typically generates 0.3%–0.7% in annual after-tax alpha — $9,000–$21,000/year on a $3M taxable account — in exchange for a 0.15%–0.35% management fee. Net benefit is positive in most environments.
Roth conversion offset: Tax losses harvested in the taxable account can offset capital gains triggered by Roth conversion. This lets you convert a larger dollar amount in a given year without crossing into higher brackets or IRMAA tiers.
Estate coordination: Direct-indexed positions receive the same stepped-up cost basis at death as ETFs. The tax losses accumulated during life, however, do not transfer — they expire at death, making early harvesting during retirement more valuable than saving losses for heirs.

What can actually go wrong at $8M

Depletion isn't the primary risk. These are:

Tax concentration in pre-tax accounts. An $8M portfolio that is 70%+ traditional IRA faces forced large taxable income via RMDs, permanently elevated IRMAA tiers, and marginal rates at 32–37% on every dollar of mandatory distribution. Account diversification — built during accumulation or the Roth conversion window — can be worth $500,000–$1M in lifetime tax savings at this level.
State estate taxes in a high-tax domicile. A couple with $8M in Oregon owes nothing federally but could face a $960,000–$1,120,000 state estate tax bill. The marital deduction defers but does not eliminate. This is a planning-addressable risk — annual gifting, superfunding, bypass trusts, and eventual domicile change all apply.
Long-term care costs. A 3–5 year nursing home stay at $100,000–$200,000/year can consume $300,000–$1,000,000 of an $8M portfolio. At $8M, self-insurance is genuinely feasible — but a dedicated LTC reserve or hybrid LTC policy reduces the longevity tail risk that could coincide with a market drawdown.
Advisor fee drag. The $3.5M opportunity cost of a 1% AUM fee on $8M is real over 20 years and should be explicitly modeled before signing an advisory agreement. At this wealth level, a fee-only fiduciary on a flat retainer consistently outperforms AUM structures on a net-of-fees basis.
Sequence-of-returns risk, early in retirement. A 30–40% portfolio decline in years 1–3 of retirement — combined with continued spending — can permanently impair long-term sustainability even at $8M. A cash and short-term bond liquidity buffer of 2–3 years of spending ($560,000–$840,000 at typical spending rates for $8M households) held outside equities is a concrete mitigation.
