Your Withdrawal Rate Tier — Real Historical Success Rates

Success rates below come from 69 actual rolling 30-year retirement windows in the historical record (1928-2025), using Damodaran's NYU Stern dataset of S&P 500 and 10-year Treasury annual returns. We simulate a 60/40 stock/bond portfolio with 3% inflation-adjusted withdrawals across every possible 30-year period, then count how often the portfolio survived. These are not theoretical Monte Carlo numbers — they are the actual historical record.

Median scenario: $537,560 (SCF 2022 mean, age 55-64)
Pre-tax, before Social Security
Standard 30-year horizon
Median scenario analysis: $537,560 portfolio with $30,000/year withdrawal = 5.6% withdrawal rate. Elevated Of the 69 historical 30-year windows in the U.S. record (1928-2025), portfolios at this withdrawal rate survived approximately ~91% of the time on a 60/40 stock/bond mix with 3% inflation adjustment. The 9% of failures clustered around portfolios that retired into the late 1960s stagflation period (1965-1969 starts).

Where You Stand vs. Other Americans (Federal Reserve 2022 Data)

The Federal Reserve's Survey of Consumer Finances (most recent: 2022, next release ~2026) tracks retirement account balances across U.S. households. Below shows where the median scenario portfolio sits among households at the typical retirement-drawdown age.

PERSONALIZED FOR YOU

Sequence-of-Returns Risk — Three Real Historical Retirement Cohorts

The order of returns matters enormously. Three real historical cohorts illustrate this, each starting with a $1,000,000 portfolio withdrawing $40,000/year (4% rule) inflation-adjusted, on a 60/40 stock/bond mix.

Retired 1966 FAILED

First decade returns (1966-1975): 1966: -10%, 1967: +24%, 1968: +11%, 1969: -8%, 1970: +4%, 1971: +14%, 1972: +19%, 1973: -14%, 1974: -26%, 1975: +37%.

High-inflation 1970s combined with two major bear markets (1973-74) depleted the portfolio. Portfolio depleted in year 28. One of the worst retirement entry points in modern U.S. history.

Retired 1990 $3.4M

First decade returns (1990-1999): -3%, +30%, +7%, +10%, +1%, +37%, +23%, +33%, +28%, +21%.

Strong bull market built a massive cushion. Even through the 2000-2002 dot-com crash and 2008 financial crisis, the portfolio was fortified. Final portfolio at year 30 (2019): approximately $3.4 million after 30 years of withdrawals — left a substantial legacy.

Retired 1982 $8M+

First decade (1982-1991): +20%, +22%, +6%, +31%, +18%, +6%, +17%, +31%, -3%, +30%. Treasuries also delivered double-digit returns through the 1980s.

The single best retirement entry year in the dataset. Final portfolio at year 30 (2011): roughly $8 million+ despite 30 years of withdrawals.

The lesson: Two retirees with identical portfolios, identical withdrawals, and identical 30-year average returns (~10%) can end with $0 or $8M+ purely based on when they retired. The years immediately around retirement entry — the "fragile decade" per Pfau & Kitces — carry outsized weight.

Mitigation strategies (in order of historical effectiveness)

  1. Reduce equity in years 1-5 of retirement. A 50/50 or 40/60 stock/bond mix gliding to 60/40 by year 10 — Pfau & Kitces (2014) "rising equity glidepath" reduces failure rate by 30-40% in worst-case sequences.
  2. Hold 2-3 years of expenses in cash/short-term Treasury. Currently yielding ~4.0% on the 2-year — never sell stocks during a decline.
  3. Use guardrails (Guyton-Klinger): Cut withdrawals 10% in down years, restore 10% in up years.
  4. Delay Social Security to 70. Provides a guaranteed inflation-adjusted income floor that reduces portfolio dependency by 15-25%.
  5. Work part-time in years 1-3. Even modest income ($15-25K) dramatically reduces portfolio drawdown during the most dangerous years.

Four Withdrawal Strategies — Quantified for the Median Scenario

Each strategy makes different trade-offs between income stability, portfolio survival, and lifestyle flexibility. Numbers below show how each plays out for the $537,560 median portfolio at a 5.6% target withdrawal rate ($30,000/year). Recalculate by adjusting inputs in the Withdrawal Rate tab.

Fixed Dollar (4% Rule) $21.5K

Withdraw 4% of starting portfolio in year 1, then increase by inflation each year. Most predictable income. Year 1: $21,502 (4% of $537,560). Year 30 at 3% inflation: $52,194. Historical survival: 97%.

Best for: Retirees prioritizing income predictability over flexibility.

Fixed Percentage $30K

Withdraw a fixed percentage of current portfolio value each year. Income fluctuates with markets. Year 1: $30,000 (5.6% of $537,560). After 20% market drop year 2: $24,000. Portfolio mathematically never depletes but income volatile.

Best for: Retirees with flexible expenses who can absorb income swings.

Guardrails (Guyton-Klinger) $29K

Start at higher initial rate (5.4%), enforce upper/lower guardrails. Cuts spending 10% if portfolio drops 20%+; raises 10% if up 20%+. Year 1: $29,028 (5.4% start). Bear-market adjustment: -10% to $26,125. Historical survival: 95%+ with discipline.

Best for: Disciplined retirees willing to monitor portfolio annually and adjust.

Bucket Strategy $30K

Three time-horizon buckets. Avoids selling stocks in downturns. Bucket 1 (yrs 1-3): $90K cash @ 3.5% HYSA. Bucket 2 (yrs 4-10): $210K bonds @ 4.3%. Bucket 3 (yrs 11+): $237K stocks. Refill in up-years. Reduces sequence risk substantially.

Best for: Retirees who want psychological comfort during market volatility.

Bottom line for the median scenario: At a 5.6% withdrawal rate, the Fixed Dollar strategy at the actual scenario rate has approximately 91% historical success. The Guardrails strategy with disciplined cuts in down years pushes that toward 95%+. The Bucket strategy provides similar longevity with better psychological stability. If withdrawal rate is above 5%, the Guardrails or Bucket strategies historically outperform Fixed Dollar.

The Optimal Withdrawal Sequence Across Account Types (2026 Rules)

Withdrawal order can save tens of thousands in taxes over a 30-year retirement. The standard hierarchy is: Taxable → Traditional → Roth, but bracket-filling strategies extract even more value by spreading Traditional withdrawals across years.

Account Type Tax Treatment on Withdrawal RMD Required? Optimal Use Phase
Taxable Brokerage Capital gains: 0%, 15%, or 20% (long-term). Qualified dividends same rates. No Years 1-10 (preserve tax-advantaged growth)
Traditional 401(k) / IRA Ordinary income: 10-37% federal plus state. Yes — age 73 (SECURE 2.0) Years 5-20 (bracket-fill 10%/12%/22% brackets)
Roth IRA / Roth 401(k) Tax-free (after age 59½ + 5-year rule). No (Roth IRA); Yes for Roth 401(k) until rolled to Roth IRA Late retirement; large one-time expenses; legacy
Health Savings Account (HSA) Tax-free for medical anytime; ordinary income for non-medical after 65. No Medical expenses anytime; supplement after 65
The bracket-filling strategy (advanced): Each year, calculate your taxable income. Withdraw from Traditional accounts up to the top of the 12% bracket. For 2026 (per IRS Rev. Proc. 2025-32), the standard deduction is $32,200 (MFJ) or $16,100 (single), so taxable income up to roughly $96,950 MFJ / $48,475 single stays in the 12% bracket. Supplement remaining cash needs with Roth withdrawals (tax-free) and taxable account sales (capital gains rates).

For the $537,560 + $30,000/year scenario: If $20K from Traditional 401(k) and $10K from a taxable brokerage with $5K basis: federal tax owed is roughly $1,200-$2,000/year (depending on filing status). Pure-Traditional withdrawal of $30K would owe ~$2,800-$3,400/year. Annual savings from optimal sequencing: $1,500-$2,200. Over 25 years: $37,500-$55,000.

2026 contribution limits (still relevant if you're working part-time)

  • 401(k): $24,500 ($8,000 catch-up at 50+; $11,250 super catch-up at 60-63)
  • IRA: $7,500 ($1,100 catch-up at 50+)
  • HSA: $4,400 self-only / $8,750 family
  • RMD age: 73 (SECURE 2.0); rises to 75 in 2033

Source: IRS Notice 2025-67, IRS Rev. Proc. 2025-32 for 2026 inflation adjustments. Roth conversions during low-income early-retirement years (typically 60-72, before RMDs and Social Security) can capture larger tax arbitrage. See Roth conversion strategies →

Bucket Strategy — Three-Tier Allocation with Live Yields

The bucket strategy segments your portfolio by time horizon. Cash for near-term, bonds for medium-term, stocks for long-term. The psychological benefit is real: knowing 3 years of expenses are in cash makes it easier to leave stocks alone during a 30% bear market. Yields below are live.

Bucket 1: Years 1-3 $90,000

Holdings: High-yield savings, money market, short-term CDs, T-bills.

Live yield: HYSA national average 3.54%; 1-year CD 3.79%; 2-year Treasury 3.80%. Above CPI (3.3%) so real return is positive.

Refill: From Bucket 2 once Bucket 1 drops to ~1 year of expenses.

Bucket 2: Years 4-10 $210,000

Holdings: Intermediate bonds (5-10yr Treasuries, investment-grade corporates, TIPS for inflation protection).

Live yield: 10-year Treasury 4.32%; investment-grade corporate ~5.5%. Stable, liquid.

Refill: From Bucket 3 in years when stocks are up 10%+.

Bucket 3: Years 11+ $237,560

Holdings: Diversified equities (US total market, international, REITs). 25+ year horizon allows full equity allocation.

Long-term return: S&P 500 average 1928-2025 = 11.86%/yr. 60/40 portfolio long-term ~9%/yr.

Withdrawal trigger: Only when stocks are up. Never forced to sell during declines.

For the median scenario ($537,560 with $30,000/year): Bucket 1 = $90,000 (3 years × $30K). Bucket 2 = $210,000 (7 years × $30K). Bucket 3 = $237,560 (remainder for long-term growth). Allocation: 17% cash / 39% bonds / 44% stocks — appropriate for a 5.6% withdrawal rate where sequence risk dominates.

Live yields from FRED (Federal Reserve Economic Data), updated weekly via FinCalcs deploy pipeline. As Bucket 1 depletes, the implicit asset allocation shifts toward equities ("rising equity glidepath") which Pfau & Kitces (2014) showed mathematically reduces sequence risk.

Things to Know

Essential concepts for understanding your results

Sequence Risk
What is sequence of returns risk?

The order of investment returns matters enormously in retirement. A portfolio averaging 7% can fail if the early years have large losses — selling shares at low prices to fund withdrawals prevents recovery. A retiree experiencing -20%, -15%, +25%, +20% has a worse outcome than one experiencing +20%, +25%, -15%, -20% despite the same average. This is the primary reason 30-year retirees should use 3.5-4% withdrawal rates and maintain cash reserves.

Bucket Strategy
How does the bucket strategy work?

Divide your portfolio into three buckets: Bucket 1 (0-2 years): cash and short-term bonds — covers immediate expenses without selling stocks during downturns. Bucket 2 (3-7 years): intermediate bonds and balanced funds — moderate growth with stability. Bucket 3 (8+ years): stock index funds — maximum growth for long-term needs. During market downturns, spend from Bucket 1 while Bucket 3 recovers. Refill buckets during bull markets.

Tax Efficiency
How do you minimize taxes on retirement withdrawals?

Withdraw from taxable accounts first (capital gains rates are lower than income rates). Then traditional 401(k)/IRA to fill lower brackets. Preserve Roth for last (tax-free growth continues). Between retirement and age 73, do Roth conversions to fill low brackets — converting $30,000-50,000/year at the 12% rate saves enormous taxes versus forced RMDs at 22-24% later. This sequencing can save $100,000-300,000 in lifetime taxes.

Spending Flexibility
How does flexible spending extend portfolio life?

Reducing spending by 10-15% during bear markets dramatically improves portfolio survival. A $60,000/year withdrawal from $1.5M (4% rate) has a 5% failure rate over 30 years. Adding the rule 'reduce to $51,000 if portfolio drops below $1.2M' reduces failure rate to under 1%. This flexibility — cutting travel, dining, and discretionary spending during downturns — is the most powerful retirement risk management tool available.

Planning Your Retirement Withdrawals

Retirement drawdown is the reverse of accumulation — and it is far more complex. During accumulation, market dips are buying opportunities. During drawdown, the same dips are threats: selling investments at depressed prices permanently depletes capital that can never recover. This is called sequence-of-returns risk, and it is the #1 threat to retirement portfolios.

The danger is real: two retirees with identical portfolios ($1,000,000), identical average returns (7%), and identical withdrawal rates (4%) can have dramatically different outcomes based purely on the order of returns. A retiree who experiences strong returns in early retirement and poor returns later ends with $1.2M+ after 30 years. A retiree who experiences poor returns first (a crash in years 1-3) and strong returns later runs out of money in year 22. Same average return, opposite outcome.

This calculator models your specific drawdown scenario — projecting how long your money lasts based on your portfolio size, withdrawal amount, asset allocation, and inflation adjustments.

The Major Withdrawal Strategies

1. Fixed Dollar (4% Rule): Withdraw a fixed percentage (typically 4%) in year 1, then increase by inflation each year. $1M portfolio: $40,000 year 1, $41,200 year 2 (at 3% inflation), $42,436 year 3. Based on the Trinity Study, this approach has a 95% success rate over 30 years with a 60/40 portfolio using historical returns. Advantage: predictable income. Risk: does not adjust for poor market conditions — you withdraw the same amount whether your portfolio is up 20% or down 30%.

2. Fixed Percentage: Withdraw a fixed percentage of the current portfolio value each year (e.g., 4% of whatever the portfolio is worth). $1M: withdraw $40,000. Portfolio drops to $800K: withdraw $32,000. Portfolio grows to $1.2M: withdraw $48,000. Advantage: you can never run out of money (mathematically impossible since you always take a percentage of what remains). Risk: income is volatile — a 30% market crash immediately cuts your income by 30%.

3. Guardrails (Guyton-Klinger): Start with an initial withdrawal rate (e.g., 5%) and set upper and lower guardrails. If the effective withdrawal rate drops below 4% (portfolio grew), give yourself a raise. If it exceeds 6% (portfolio declined), cut spending. This dynamic approach allows a higher initial withdrawal rate (5-5.5%) while maintaining safety through spending adjustments. It requires flexibility but produces the highest sustainable income for most retirees.

4. Bucket Strategy: Divide your portfolio into time-based buckets. Bucket 1 (years 1-3): cash and short-term bonds for immediate expenses. Bucket 2 (years 4-10): intermediate bonds and balanced funds. Bucket 3 (years 10+): aggressive growth (stocks). Spend from Bucket 1 during downturns (no need to sell stocks at a loss), replenish Bucket 1 from Bucket 2/3 during recoveries. Psychologically reassuring and mechanically effective at managing sequence risk.

The Tax-Efficient Withdrawal Order

Which account you withdraw from affects your tax bill by thousands annually. The IRS treats different account types differently:

Taxable brokerage accounts: Withdrawals taxed at capital gains rates (0%, 15%, or 20% for long-term gains). Most tax-efficient for large withdrawals. Qualified dividends and long-term gains in the 0% bracket (taxable income under $94,050 MFJ in 2026) are completely tax-free — a powerful tool for low-income retirement years.

Traditional IRA/401(k): Withdrawals taxed as ordinary income (10-37%). Required Minimum Distributions begin at age 73. RMD at 73 on a $500,000 balance: approximately $18,870. At 80: approximately $22,730. At 85: approximately $26,900. These forced withdrawals can push you into higher brackets, trigger IRMAA Medicare surcharges ($1,000-$5,000+/year), and increase Social Security taxation.

Roth IRA/401(k): Withdrawals completely tax-free. No RMDs during owner's lifetime. Ideal for: supplementing income without increasing AGI, funding large one-time expenses (new car, home repair) without bracket impact, and leaving tax-free assets to heirs.

The bracket-filling strategy: Each year, withdraw from Traditional accounts to fill the 10% and 12% brackets (up to $94,050 MFJ in taxable income for 2026). Supplement with Roth withdrawals for additional needs. Use taxable accounts for large expenses, taking advantage of the 0% long-term capital gains rate when applicable. This approach minimizes lifetime tax and maximizes portfolio longevity.

How Long Will Your Money Last? Key Benchmarks

Based on historical Monte Carlo simulations with a 60/40 stock/bond portfolio and 3% inflation adjustment:

3% withdrawal rate: 99%+ success over 30 years. Portfolio likely grows in real terms. Best for early retirees (age 50-55) needing 35-40+ years of income or those leaving a legacy.

4% withdrawal rate: 95% success over 30 years. The classic benchmark. May deplete portfolio in the worst 5% of historical scenarios (extended depression + high inflation). Appropriate for age 60-65 retirees with 25-30 year horizons.

5% withdrawal rate: 75-82% success over 30 years. Higher risk of depletion but provides 25% more income. Appropriate with flexible spending (willingness to cut 10-15% during downturns) or shorter horizons (20-25 years). The guardrails approach makes 5% viable.

6%+ withdrawal rate: Below 60% success over 30 years. Only appropriate for very short time horizons (15-20 years), large Social Security or pension income supplementing withdrawals, or willingness to significantly reduce spending as portfolio declines.

Frequently Asked Questions

How much can I withdraw from retirement accounts each year?
The safe starting point is 4% of your portfolio, adjusted annually for inflation (the 4% rule). On $1,000,000: $40,000/year. With spending flexibility (willing to cut 10-15% in down markets), you can start at 5%. For early retirees needing 35-40 years: use 3-3.5%. The right rate depends on your time horizon, flexibility, other income sources (Social Security, pension), and risk tolerance.
What is sequence-of-returns risk?
The risk that poor investment returns in the early years of retirement permanently damage your portfolio — even if later returns are strong. A 30% crash in year 1 forces you to sell at depressed prices to fund withdrawals, and those sold shares cannot participate in the recovery. Mitigation: keep 2-3 years of expenses in cash/bonds (bucket strategy), reduce withdrawals during market downturns, and maintain enough equity for long-term growth.
Should I withdraw from my 401k or Roth first?
Generally, withdraw from Traditional accounts (401k/IRA) first to fill the lower tax brackets (10% and 12%), then supplement with Roth for additional needs. This minimizes lifetime taxes. Exception: before age 73, strategically convert Traditional to Roth during low-income years to reduce future RMDs. After 73, RMDs are mandatory from Traditional accounts — use Roth to supplement without increasing your tax bracket.
When do Required Minimum Distributions start?
Age 73 (per SECURE 2.0). Your first RMD must be taken by April 1 of the year after you turn 73 — but delaying the first RMD means taking two RMDs in that year (potentially pushing you into a higher bracket). The RMD amount is your Traditional IRA/401k balance as of December 31 of the prior year divided by an IRS life expectancy factor. At 73 with $500,000: approximately $18,870. The penalty for missing an RMD: 25% of the amount not withdrawn.
What is the guardrails withdrawal strategy?
Start with a higher initial withdrawal rate (5%) and set rules: if the effective rate drops below 4% (portfolio grew significantly), increase spending. If it rises above 6% (portfolio declined), reduce spending by 10%. This dynamic approach has been shown to support higher initial withdrawals than the rigid 4% rule while maintaining safety — because you adjust spending based on actual portfolio performance rather than ignoring it.
