For years, $1 million was the benchmark -- the ideal amount saved for retirement. However, given the number of variables involved in retirement expenses, it's impossible to determine an exact amount that fits every retiree.
If you're aiming for $1 million in a retirement account and wonder how long it will last you, you may not like the answer. That's because it depends.

If you were born in 1960 or later, your full retirement age (FRA) is 67. Whether you work until then or slip out a little early, financial planners assume a retirement horizon of 25 to 35 years. Whether the money will last that long or not depends on several factors, including how much you plan to withdraw annually, the average rate of return, and whether inflation holds steady or heads for the stratosphere.
This table illustrates how a single factor can alter how long $1 million lasts.
| I will withdraw this percentage in the first year... | I will increase my withdrawals by this much annually... | I expect an average annual rate of return of this much... | How long $1 million will last... | |---|---|---|---| | 4% | 1% | 6% | Beyond 30 years | | 5% | 1% | 6% | Beyond 30 years | | 6% | 1% | 6% | Roughly 25 years | | 4% | 2% | 7% | Beyond 30 years | | 5% | 2% | 7% | Beyond 30 years | | 6% | 2% | 7% | Roughly 24 years |
As the table indicates, how long $1 million lasts in retirement depends on factors you can control, such as how much you plan to withdraw annually and how much you'll increase your withdrawals by each year. It also depends on factors you can't control, like the average rate of return.
Assuming dividends are reinvested, the average rate of return for the S&P 500 (SNPINDEX: ^GSPC) over the last 150 years is 9.434%. Adjusted for inflation, the average rate of return is 6.981%, or just shy of 7%. What's remarkable is that this average accounts for both periods of U.S. prosperity and deep financial depressions.
And that's the point: As a retiree, you have no control over what's happening with the overall economy. You're sure to live through both busts and booms, so you need a plan for both. Booms are great because you can withdraw the amount you want from your retirement account without worrying about how the withdrawal will impact your balance.
However, you want a plan for periods when the market seems on life support. It's during that time when the value of your portfolio is at a low that you don't want to sell, which means you don't want to make any withdrawals. That's because you'll need to sell more assets to net the money you're counting on for living expenses.
Your best bet is to create an easy-to-access cash account. That way, while the market is toughing it out, you have a source to draw funds from -- just long enough to protect your retirement account. When it comes to interest-bearing accounts, you have plenty of options, including high-yield savings accounts (HYSAs), money market deposit accounts (MMDAs), short-term certificates of deposit (CDs), and short-term Treasuries (T-bills).
No matter how much anyone tells you that you must save for retirement, $1 million is quite an accomplishment. Properly managed, it can last a lifetime.

Four leading AI models discuss this article
"The article’s claim that $1M can reliably fund 25–35 years rests on optimistic return assumptions and static withdrawal rules, ignoring sequence risk, healthcare costs, taxes, and fees; under plausible conditions, many retirees may not reach a three-decade horizon."
The piece relies on a long-run average (roughly 7% real return for equities) and fixed withdrawal assumptions to claim $1M lasts 25–30+ years. It understates real-world risks retirees face: sequence-of-returns risk during downturns, rising healthcare costs, taxes and fees, and the uncertain path of future inflation and interest rates. A cash buffer helps liquidity but doesn’t solve tail risks if a bear market coincides with longer retirement horizons. Promotions (Stock Advisor) and sensational Social Security figures also distort objective planning. In short, the article paints a best-case, not a robust, stress-tested, forward-looking scenario.
If future markets deliver similar long-run real returns and you optimize Social Security and taxes, $1M could still last 30+ years, so the article’s cautionary framing may be overly pessimistic.
"Average annualized returns are a poor metric for retirement planning because they mask the catastrophic impact of sequence of returns risk during early retirement years."
The article’s reliance on a 6-7% average return for the S&P 500 is dangerously misleading for retirees. It ignores 'sequence of returns risk'—the reality that a 20% market drawdown in the first three years of retirement can permanently impair a portfolio's longevity, regardless of long-term averages. Furthermore, the piece treats inflation as a static variable, whereas healthcare costs for retirees often outpace CPI significantly. While the advice to hold cash/T-bills is sound, the article glosses over the 'cash drag'—the reality that keeping 2-3 years of expenses in low-yield assets during high-inflation regimes erodes purchasing power, potentially forcing retirees back into the labor market.
The article's focus on long-term averages is statistically sound for those with flexible spending habits who can scale back withdrawals during market volatility.
"The article's optimism hinges on executing a perfect withdrawal strategy during market crashes—a behavioral test most retirees fail, making sequence-of-returns risk the real threat to $1M longevity, not average returns."
This article conflates two separate problems: (1) whether $1M lasts 25–30 years (solvable with math), and (2) whether retirees will actually execute the discipline required. The table assumes 6–7% real returns and steady withdrawals, but ignores sequence-of-returns risk: a 2008-style crash in year one of retirement is catastrophic even if markets recover later. The 'cash buffer' solution is mentioned but undersized—most retirees don't hold enough dry powder. Critically, the article assumes S&P 500 exposure; many retirees hold bonds, which drag returns. Finally, the Social Security 'secret' ($23.76K bonus) is vague marketing, not analysis.
The 150-year S&P average of 7% real return is robust precisely because it survived depressions; a disciplined retiree following the 4–5% withdrawal rule historically has survived every drawdown, so the article's core math is sound.
"Elevated valuations make the article's 6-7% real return assumptions optimistic, likely shortening safe withdrawal horizons below the 25-30 years claimed."
The article presents $1M as viable for 25-30 years via 4-6% initial withdrawals and a cash buffer, leaning on 150-year S&P 500 real returns near 7%. This glosses over sequence-of-returns risk during early retirement drawdowns, which can permanently impair portfolios even with historical averages. It also ignores rising longevity, healthcare inflation, and current high equity valuations that compress forward returns below the cited long-term mean. The piece functions partly as lead-gen for Motley Fool services, framing controllable factors while understating tail risks retirees cannot easily hedge.
Bengen's original 4% rule and subsequent studies show success rates above 80% even with 30-year horizons when withdrawals adjust for poor early markets, suggesting the article's scenarios remain realistic for most diversified investors.
"Forward real returns are likely lower than 7% and starting valuations matter more now, so a fixed 4–5% withdrawal path with a static horizon is too optimistic without dynamic withdrawals and a larger cash cushion."
Claude’s defense of a 7% real return and the 4–5% withdrawal rule ignores that current starting valuations, rising healthcare costs, and lengthening lifespans amplify sequence-of-returns risk far more than the long-run average implies. If forward returns are closer to 3–5%, the fixed-path math collapses without dynamic withdrawals and a larger cash cushion. The article’s math could overstate confidence in a 25–30 year horizon.
"High current market valuations significantly increase the risk of failure for standard withdrawal rules, regardless of historical averages."
Claude, your reliance on historical 4% withdrawal success rates ignores the current CAPE ratio (Cyclically Adjusted Price-to-Earnings) of the S&P 500, which sits well above its long-term mean. When starting valuations are this elevated, the probability of a 'lost decade' of real returns increases, rendering static withdrawal rules mathematically dangerous. We are not just debating sequence risk; we are debating the fundamental compression of the equity risk premium that historically sustained those 30-year retirement horizons.
"Elevated valuations and sequence-of-returns risk are distinct tail risks; the article underestimates both, but conflating them obscures which one actually breaks a $1M portfolio first."
Gemini's CAPE ratio point is sharp, but conflates two separate risks. Elevated valuations compress *forward* returns—agreed. But that's a 10–15 year headwind, not a 25–30 year death sentence. Sequence risk and valuation risk operate on different timescales. A retiree retiring today faces worse *near-term* odds if markets crater in years 1–3, regardless of CAPE. The article doesn't address either clearly. We're debating whether $1M fails due to low returns *or* bad timing. Both matter, but they're not the same problem.
"Valuation compression and sequence risk overlap in the critical first decade, amplifying failure odds beyond what separate analysis implies."
Claude's separation of near-term sequence risk from 10-15 year valuation headwinds understates their overlap. Elevated CAPE today directly lowers returns in years 1-10, the exact window where early drawdowns inflict permanent portfolio damage. For 25-30 year retirements this compounds rather than isolates, making fixed withdrawal math more fragile than either risk considered alone.
The panel consensus is that the article understates risks and overstates the longevity of a $1M retirement portfolio. Key risks include sequence-of-returns risk, rising healthcare costs, and elevated equity valuations compressing forward returns.
