The 4% Rule Explained: Does a $1M Portfolio Last 30 Years in 2026?
A $1M portfolio at 4% gives $40,000/year before tax. Whether it lasts 30 years depends on sequence of returns, inflation, asset mix, and tax treatment.

A $1M portfolio at 4% gives you $40,000 a year — $3,333 a month before tax. The harder question isn’t the withdrawal math. It’s whether your portfolio survives a bad market in years one through five of retirement, because that timing is the real variable.
Where the 4% Rule Actually Came From
The rule traces back to researcher William Bengen’s 1994 paper and a follow-up study from Trinity University. They ran historical simulations on 30-year retirement windows starting from 1926. Finding: a 4% initial withdrawal, adjusted annually for inflation, survived 95%+ of all historical 30-year periods when the portfolio held a stock-and-bond mix.
That’s the origin. Not a guarantee. A historical success rate.
Most people with $1M in retirement savings don’t realize the study assumed a 50/50 or 60/40 portfolio. A 4% withdrawal from a portfolio sitting in money market funds is a plan to run out of money.
📊 The $1M Portfolio — What 4% Looks Like Year by Year
Year Portfolio (6% avg. return) Annual withdrawal Inflation-adjusted withdrawal 1 $1,000,000 $40,000 $40,000 5 $942,000 $40,000 $43,300 10 $866,000 $40,000 $50,200 20 $690,000 $40,000 $67,200 30 $441,000 $40,000 $90,300 Illustrative projection · 6% nominal return · 3% annual CPI · no Social Security offset
The portfolio shrinks. Expected. The question is whether it hits zero before year 30. At 6% returns and 3% inflation, $441,000 remains at year 30. Sequence of returns can flip that entirely.
The Sequence-of-Returns Problem
Retire in 2000 with $1M. The S&P 500 drops 49% over the next two years. You’re still withdrawing $40,000 a year. By 2002, your portfolio is roughly $480,000 — not because you did anything wrong, but because you sold depressed assets to cover expenses. That money never recovers.

Retire in 2010 with $1M and you catch a decade-long bull run. Same strategy, wildly different outcomes.
This is the real risk in 2026. Equity valuations are elevated. Bond yields are better than the 2010s, which helps fixed-income allocations. But a bear market in years one through five of retirement compresses a 30-year window fast.
Your $40,000 Withdrawal — After Tax
Retirement withdrawals aren’t tax-free. Every dollar from a traditional IRA or 401(k) is ordinary income. Roth distributions are tax-free. The account type matters as much as the withdrawal rate.
Here’s the 2026 tax picture on a $40,000 annual traditional IRA distribution — single filer, Arizona, standard deduction:
📊 $40,000 Retirement Withdrawal — Estimated 2026 Tax Snapshot (Arizona)
Annual Monthly Bi-weekly Gross withdrawal $40,000 $3,333 $1,538 Federal income tax –$2,762 –$230 –$106 FICA (SS + Medicare) –$0 –$0 –$0 Arizona income tax –$625 –$52 –$24 Take-home $36,614 $3,051 $1,408 Estimated · 2026 IRS brackets · single filer · $15,000 standard deduction · IRS Pub 15-T
Quick math: $40,000 gross → $36,614/year — $3,051/month or $1,408 bi-weekly after federal and Arizona state tax. Estimated · 2026 IRS brackets · single filer · standard deduction.
IRA and 401(k) distributions aren’t subject to FICA. That’s one tax most retirees don’t pay. But federal and state income tax still apply, cutting $1,386 from a $40,000 withdrawal in Arizona.
Living on $3,051 a Month in Phoenix
Phoenix is the most common landing spot for retirees escaping high-cost states. One-bedroom rents in the Tempe and Chandler corridors run around $1,250/mo per Zillow, Apr 2026.
That’s 41.0% of your $3,051 monthly take-home — above the 30% threshold financial planners use as the standard affordability cut-off. At that ratio, building savings takes serious discipline. Owning your home free and clear removes this entirely — which is functionally a $1,250/month raise on this budget.

After rent and essentials, $762/month remains. That’s not nothing — but it’s not padding either. One car repair or medical copay absorbs most of it.
States Where $40,000 Goes Further
Not all states tax retirement income the same way. The gap between the best and worst is $2,700 a year — $81,000 over 30 years before any compounding.
Estimated annual after-tax income on $40,000 IRA withdrawal — 6 states compared (2026):
- 🟢 Florida — ~$37,238 (no state income tax; Social Security fully exempt)
- 🟢 Texas — ~$37,238 (no state income tax)
- 🟢 Nevada — ~$37,238 (no state income tax)
- 🟡 Arizona — ~$36,614 (2.5% flat state income tax)
- 🟡 Colorado — ~$36,400 (4.4% flat; $24,000 pension exemption for retirees 65+)
- 🔴 California — ~$34,538 (up to 9.3% on $40,000; no retirement income exemption)

People relocating from California to Florida for retirement aren’t overreacting. The difference is $2,700 a year, real money.
Does the 4% Rule Still Hold in 2026?
Some planners now recommend 3.3–3.5% as the updated safe rate for retirements starting this year. Elevated equity valuations and uncertain bond returns over the next decade are the reasoning.
At 3.5%: $35,000/year from $1M. At 3.3%: $33,000/year. That’s $7,000 less annually than the classic rule — $583/month.
What you need at different spending levels:
| Annual spending | At 4% rule | At 3.5% rule |
|---|---|---|
| $40,000 | $1,000,000 | $1,143,000 |
| $50,000 | $1,250,000 | $1,429,000 |

Quick Answers About the 4% Rule
What does 4% of $1 million equal per month? $40,000 a year, or $3,333/month gross. After estimated 2026 federal and Arizona state tax, a single filer takes home roughly $3,051/month.
Is the 4% rule still valid in 2026? It’s a historical benchmark, not a law. It holds over 30-year periods with a 60/40 portfolio. Retiring with 100% bonds or 100% equities changes the odds. A bear market in your first five years changes them further.
How long does $1M last at 4% withdrawal? In historical simulations, 30+ years in 95%+ of scenarios with a balanced portfolio. An early bear market — like 2000–2002 — can compress that to 20–22 years. Your actual asset allocation matters more than the rule.
What if I retire at 55, not 65? A 35–40 year window changes the math significantly. Most planners recommend 3.5% or lower for early retirement. At 3.5%, you need $1.14M to safely spend $40,000/year. Social Security doesn’t start until 62 at the earliest.
Does the 4% rule account for inflation? Yes — the original model increases withdrawals by CPI each year. Start at $40,000; at 3% inflation, year two is $41,200, year three is $42,436. What the simulations can’t model is 6–8% sustained inflation over a full decade.
Three Moves That Stretch $1M Further
1. Delay Social Security to 70. Every year you delay past 62 adds roughly 8% in permanent benefit. Going from 62 to 70 increases your monthly check by up to 76%. Fund early retirement from your portfolio; let Social Security grow. Most people overlook this as the highest-return move available to them at zero cost.
2. Roth conversions in the gap years. Retire at 62 and delay Social Security to 70. That’s an 8-year window with low taxable income. Convert $30,000–$40,000 a year from traditional to Roth during that window. You lock in the 12% federal bracket and reduce RMDs — which kick in at 73 and can push you into the 22–24% bracket.
3. Flexible spending in down markets. Rigid 4% rules fail in bear markets because you’re selling low. Cutting from $40,000 to $35,000 in a year the market drops 20% preserves enough capital to recover. Dynamic withdrawal strategies outperform rigid rules in historical simulations according to research from the Bureau of Labor Statistics and retirement income analysts.

Frequently Asked Questions
What’s the bi-weekly withdrawal from a $1M portfolio at 4%? $40,000 a year equals $1,538 bi-weekly gross. After 2026 federal and state tax (single filer, traditional IRA, Arizona), you’re looking at roughly $1,408 bi-weekly in hand. Check the IRS Tax Withholding Estimator if you set up withholding on IRA distributions.
Is $1M enough to retire in a major city? In Phoenix or Austin, workable — if your housing is paid off. In New York, San Francisco, or Boston, $40,000/year from a portfolio isn’t enough without Social Security or other income. You’d realistically need $1.5M–$2M in those markets.
What if I’m self-employed and haven’t hit $1M yet? Catch-up contributions close that gap faster than most people expect. A Solo 401(k) lets you contribute up to $23,500 as employee plus 25% of net self-employment income — total limit $70,000 in 2026. At $60,000 net freelance income, you can sock away $38,500 in one year. Use our self-employment tax calculator — SE tax adds 14.13% on net earnings, which catches a lot of people off guard.
Roth vs. traditional IRA: which works better with the 4% rule? Same withdrawal rate, different tax treatment. $40,000 from a Roth is tax-free. $40,000 from a traditional IRA costs you $2,762 in federal tax plus state. On a $1M portfolio, moving 40–50% into Roth accounts before retirement can add $3,000–$6,000 in annual after-tax income. The conversion math is best run 5–10 years before your target date.
