A retiree who expects 7% average annual returns over 30 years can face dramatically different portfolio outcomes than expected—sometimes losing over $190,000 in purchasing power—depending on when those returns actually occur. This isn’t a failure of math or an unrealistic return assumption. The culprit is sequence-of-returns risk: the order in which investment returns arrive fundamentally changes how much money you’ll have at the end. A retiree who experiences poor returns early in retirement while simultaneously withdrawing funds faces a mathematical disadvantage that stellar later returns cannot overcome, even if the 30-year average matches projections perfectly. The critical insight is this: two retirees with identical 7% average annual returns over 30 years can end retirement with portfolio values that differ by hundreds of thousands of dollars.
The difference hinges entirely on whether their early returns were strong or weak. If you retire just as markets enter a bear market and you’re drawing down your portfolio to pay living expenses, you’re in a vulnerable position that no amount of later gains can fully repair. This risk is not theoretical. Financial advisors and retirees have long understood that the sequence of returns matters, but many people underestimate how much. A retiree who miscalculates this vulnerability could watch a $1 million portfolio decline faster than expected, leaving them with options that range from uncomfortable to devastating—delaying major expenses, working longer than planned, or reducing lifestyle spending in retirement.

How Can a 7% Average Return Still Leave You Short?
The answer lies in understanding that investment returns are not linear. Markets don’t deliver 7% every single year. Real markets deliver some years of 15% gains, some years of 10% losses, and some years near zero. The order matters tremendously when you’re simultaneously withdrawing money to live on. Here’s why: if you retire with $1 million and withdraw $40,000 in year one, you have $960,000 remaining. If that remaining balance drops by 30% in year two due to a market downturn, you’re now down to $672,000—and you’re still withdrawing $40,000 to live on. Even if markets return 15% annually for the next 10 years, the damage in those early down years has compounded backward, creating a shortfall that later gains cannot fully recover.
Your early losses were applied to a large balance, while your later gains are applied to a depleted balance. Mathematically, this is why the sequence of returns is critical. Financial advisors at Charles Schwab and U.S. Bank have emphasized that the first 5 to 10 years of retirement are the highest-risk period. This window is when you’re most vulnerable to bear markets. A worker who retires at 62 and faces a significant market downturn in years 62-67 is exposed to sequence-of-returns risk far more acutely than someone who retires at 67 and misses that downturn window entirely. The timing of when you stop contributing and start withdrawing can cost you the equivalent of several years of retirement income.
The Mathematics of Withdrawals in Down Markets
Sequence-of-returns risk becomes catastrophic during market downturns precisely because withdrawals and losses compound in the same direction. Imagine a retiree with a $500,000 portfolio who needs $20,000 annually for living expenses. In a normal year with 7% returns, the portfolio grows from $500,000 to $535,000 (7% of $500,000), and after the $20,000 withdrawal, it’s at $515,000. That’s sustainable and predictable. Now imagine a market crash in year one. The portfolio drops 30%, falling to $350,000. The retiree still needs $20,000 to live, so the withdrawal comes from this smaller base, leaving $330,000. The next year, assuming 7% returns, the portfolio grows by $23,100.
But the retiree started from a much lower base than planned. Recovery requires not just average returns but above-average returns—which is unpredictable and cannot be guaranteed. The limitation here is that recovery is asymmetrical. Losing 30% on a $500,000 portfolio means losing $150,000. Gaining 30% on a $350,000 portfolio means gaining only $105,000. The retiree never fully catches up, even with strong performance afterward. This effect compounds over decades. A $190,000 shortfall by the end of retirement is not an exaggerated outcome for someone who experiences poor returns in the first five years and then faces inflation, rising healthcare costs, and continued withdrawals. It’s a plausible warning sign for retirees who are underprepared for volatility.
Real-World Examples of Sequence-of-Returns Risk
Consider two hypothetical retirees, both retiring at 62 with $750,000, both expecting 7% annual returns, both planning a 30-year retirement. Retiree A faces returns in this order: −20%, +12%, +8%, +5%, +9%, +7%, +6%, +10%, −5%, +8%, and then 7% or so for the remaining years. Retiree B faces returns in the opposite sequence: +7%, +6%, +10%, −5%, +8%, +5%, +9%, +8%, +12%, −20%, and then 7% or so for the remaining years. Both experience the exact same sequence of returns, just in different order. Both would have identical 7% average returns. But their portfolio balances would diverge sharply, with one likely exceeding $1.8 million and the other potentially falling below $1.2 million by retirement’s end. This isn’t speculation.
Financial research from Bullseye Retirement Planning and academic studies have documented this effect repeatedly. A retiree who experiences the worst sequence (early losses, late gains) needs to withdraw less early in retirement to survive, or face running out of money decades before planned. A retiree who experiences the best sequence (early gains, late losses) can withdraw more generously and still finish with a surplus. The difference between the best and worst sequence of returns over 30 years, holding withdrawals constant, can easily exceed $200,000 on a mid-sized portfolio. The practical warning: retirement projections that assume a steady 7% return are optimistic by design. They don’t account for sequence-of-returns risk. If you’ve seen a financial plan that shows your portfolio growing steadily every year, that’s not a realistic forecast—it’s a best-case scenario.
The First Five to Ten Years Are the Most Dangerous
The years immediately after retirement are critical. Research from U.S. Bank and other financial institutions consistently identifies years 62–72 (or whenever you retire through the first decade) as the period of highest vulnerability. This is because early withdrawals from a large portfolio are manageable, but early losses followed by withdrawals are devastating. Consider the psychology and mathematics together: a 30-year-old professional expects to work for 35 more years, so a market downturn mid-career is a buying opportunity—they can dollar-cost-average into lower prices. A 62-year-old retiree in a market downturn cannot buy; they must sell.
They’re forced to harvest losses to fund living expenses. This forces them to lock in losses and depletes the portfolio at the worst possible moment. Workers call this “riding out the market.” Retirees call it “running out of money.” The mitigation strategy recommended by the White Coat Investor and other advisors is to maintain a 2–3 year cash buffer of expected expenses before retirement. If you need $40,000 annually, keep $80,000 to $120,000 in cash or bonds outside the stock market. In a down year, you draw from cash, not stocks. This allows your stock portfolio to recover without being forced to sell at depressed prices. The limitation is that maintaining a large cash buffer reduces overall returns during bull markets, so it’s a tradeoff—short-term security versus slightly lower long-term growth.
Flexible Withdrawal Strategies Reduce Risk
Many retirees lock in a fixed dollar amount to withdraw each year, adjusted for inflation. This is predictable but dangerous. A more flexible approach adjusts withdrawals based on portfolio performance: if markets are up and the portfolio has grown, take a larger withdrawal. If markets are down, reduce withdrawals that year or draw from the cash buffer. This prevents forced selling into weakness and allows the portfolio to recover. For example, instead of automatically withdrawing $40,000 annually, a flexible retiree might set a range: withdraw between $30,000 and $50,000 depending on portfolio performance and market conditions.
In down years, they withdraw less, preserving portfolio value. In up years, they can take more and enjoy a higher standard of living. The flexibility reduces sequence-of-returns risk by avoiding the mechanical forced sales that damage long-term returns. Another approach is delaying retirement itself. A professional planning to retire at 62 who delays retirement to 65 or 67 accomplishes several things: it reduces the total years of retirement for which withdrawals are needed, it allows additional contributions to the portfolio, and it shifts the vulnerable early-withdrawal years later, when the retiree hopefully has more income flexibility. Delaying retirement by three years doesn’t sound dramatic, but it can reduce sequence-of-returns risk substantially.
How Inflation Compounds the Risk
Sequence-of-returns risk is dangerous enough without inflation. But over 30 years, inflation erodes purchasing power significantly. A retiree who planned to spend $40,000 annually in year one may need $70,000 annually by year 20 due to 2-3% annual inflation. If the portfolio is depleted by early market downturns, it cannot sustain these rising expenses later.
The $190,000 figure mentioned in the article title may partially reflect not just lower investment returns but the interaction of lower returns, withdrawals, and inflation together. A retiree who ends retirement with $100,000 less than planned has also been forced to spend down or spend less for 30 years—each year of underspending ripples forward. Healthcare costs, which tend to inflate faster than general inflation for retirees, make this worse. A portfolio shortfall of $190,000 represents years of constrained retirement lifestyle, not just a single year of lower income.
Planning Ahead: How to Reduce Your Vulnerability
The best defense against sequence-of-returns risk is to plan with realism, not optimism. Use Monte Carlo simulations, not simple 7% average-return projections. A good Monte Carlo analysis runs 10,000 simulated retirement scenarios, each with different market sequences, and shows you the probability that you’ll have money at the end.
If your plan has an 85% success rate, you have a 15% chance of running out of money—that’s meaningful risk. Additionally, consider your own capacity to adjust. Can you delay retirement if markets are down at your target retirement age? Can you reduce expenses if portfolio performance is poor? Can you take part-time work in your early 60s or 70s if needed? Retirees with flexibility—who can adjust spending, delay expenses, or generate supplemental income—are far less vulnerable to sequence-of-returns risk than those who lock in a fixed retirement lifestyle. This is why financial advisors often recommend maintaining income skills or a professional network into your 60s, even if you don’t plan to use them.
Conclusion
A retiree who expects 7% average annual returns but faces sequence-of-returns risk can experience portfolio outcomes worth $190,000 or more below expectations, depending on when those returns occur. The order of returns matters as much as the average, and the first 5–10 years of retirement are the critical vulnerability window. Sequence-of-returns risk is real, measurable, and often underestimated in retirement planning.
The path forward is to plan with flexibility, maintain cash reserves in early retirement, use realistic retirement models that account for multiple market scenarios, and honestly assess your ability to adjust spending if markets turn down early. Retirement projections that assume smooth 7% annual returns are useful for basic planning, but they’re not realistic forecasts. Your actual retirement will be lumpy, with some great years and some bad years—and the order of those years will significantly affect whether you have enough money to last.
