A Market Drop at 67 Does Twice the Damage of One at 57. Here’s the Math, and the Buffer That Blunts It.
Two retirees, identical average returns, wildly different retirement outcomes. The culprit is a timing quirk that turns an ordinary market drop into a permanent loss, and most people heading into retirement have no idea how exposed they are.

Sequence-of-returns risk is the reason two retirees with identical average returns can end up with very different outcomes. A portfolio that drops 20% at age 57 has a decade of contributions and compounding to repair it. The same drop at 67 lands on a portfolio being drawn down for living expenses, so every dollar withdrawn during the drawdown is sold at a loss and never earns back the recovery.
Financial planners often estimate that a bad first year of retirement can shorten portfolio longevity by close to half compared with the same loss suffered ten years earlier. The math turns on what the portfolio has to do while it is down, not on the size of the drop itself.
The Math at 57 Versus 67
Consider a saver in the average Fidelity age bracket. The reported average 401(k) balance for ages 55 to 59 is $244,900, and for ages 65 to 69 it is $251,400. A 20% market drop takes both balances down by roughly $49,000 to $50,000 on paper. At 57, the account still receives contributions up to the $24,500 2026 elective deferral limit plus an $8,000 catch-up. Those contributions buy shares at the depressed price, and the paper loss has ten more years to reverse.
At 67, the same balance is funding withdrawals. Fidelity’s guideline calls for roughly 10x salary saved by age 67 and assumes a 45% income-replacement target after Social Security. If the retiree pulls the standard 4%, roughly $10,000 in the first year comes out of a portfolio already down 20%. Those shares are sold at the low and never participate in the rebound. That is the doubling effect: the drop happens once, but the withdrawal magnifies it every year until markets recover.
Why the Buffer Is Thinner Right Now
The cushion Americans bring into a downturn has shrunk. The personal savings rate has fallen from 6.2% in 2024 Q1 to 2.8% in 2026 Q2, according to Bureau of Economic Analysis data, even as per capita disposable income rose to $68,958. Average annual household expenditures were $78,535 in the most recent BLS survey, so a smaller share of income is being set aside against a larger spending base.
Market conditions look calm on the surface. The VIX closed at 16 on July 31, 2026, within the normal 15 to 20 range, and the S&P 500, tracked by the SPDR S&P 500 ETF Trust (NYSEARCA:SPY), is up roughly 23% over the past year. That calm is recent. The VIX hit 31 on March 27, 2026, and consumer sentiment sits at 49.5, in the bottom decile historically.
The Buffer That Blunts It
The tool that neutralizes sequence risk is a spending reserve held outside equities. Two to three years of cash and short-duration bond withdrawals mean the retiree can pause equity sales during a drawdown and let the stock portion recover. With the 10-year Treasury yield near 4.8%, near its 12-month high, the reserve now earns real income rather than sitting idle.
Social Security provides the other layer, and the 2026 cost-of-living adjustment is 2.8%, and the average retired worker receives roughly 40% of pre-retirement income from the program. That inflation-linked income does not fall when markets fall, which is exactly the property a market drawdown demands from a retirement plan.
What the Data Says to Do
The math points to three specific actions. Anyone within five years of 67 should start with a two to three-year cash and bond reserve, funded in advance, so that early withdrawals never force a fire sale of equities when prices are down.
Second, workers 60 to 63 can use the higher $11,250 super catch-up to accelerate the reserve build while still working.
Third, delaying Social Security past the full retirement age raises the guaranteed income base that carries the highest weight during a downturn, since each year of delay increases the benefit and every future 2.8%-type COLA is applied to a larger check.
The drop at 67 does more damage than the drop at 57 because the portfolio has less time and more obligations. The buffer works by giving the portfolio back the one thing the withdrawal took away: time.
