A 62-year-old single retiree just walked away from work with a $2.4 million portfolio split between 60% stocks and 40% bonds. He plans to make the standard 4% withdrawal ($96,000 in year one), and adjust for inflation each year over a 30+ year retirement. On paper, a 4% withdrawal rate against a portfolio expected to average around 7% annually looks bulletproof. But if bad market years arrive first, the same average return produces a wildly different ending balance.
This question appears constantly on Reddit’s r/financialindependence and Bogleheads forums. Keep in mind that Bill Bengen’s original 1994 research that produced the 4% rule was built to survive worst-case starting years like 1966 and 1973.
Our Case Study
- Age and household: 62, single, retired this year
- Portfolio: $2.4 million, 60% equities / 40% bonds
- Spending plan: $96,000 in year one, inflation-adjusted thereafter
- Time horizon: 30+ years
- What’s at stake: Whether the same average return leaves him with roughly $2.8 million or roughly $1.1 million at age 80
Sequence-of-returns risk is the single most important variable here. When adding money to a portfolio, a bad early stretch is a gift because you buy cheap. When pulling money out, a bad early stretch is poison because every dollar withdrawn at a low price is a dollar that can never compound back.
The 2000-2002 dot-com crash is a good example. The S&P 500 fell roughly 39% from January 2000 through December 2002, with three consecutive losing calendar years of roughly -9%, -12%, and -22%. A retiree who started with $2.4 million in January 2000 and pulled $96,000 plus inflation each year would have watched the portfolio drop to roughly $1.5 million by the end of year three before that year’s withdrawal. Continue withdrawals at $96,000-plus inflation for the next 12 years and the balance lands near $1.1 million by age 80.
Inflation compounds the problem and is a major concern in 2026. The Consumer Price Index sits at around 332, up from roughly 321 a year earlier, and the $96,000 check must grow with that number every year.
Plug in different return assumptions and the spread between success and trouble is stark. The lesson from Bengen’s original work and subsequent Big ERN sequence-risk studies is that cohorts starting in 1966, 1973, and 2000 all required either spending cuts or saw portfolios fail by year 30.
Four Moves That Could Change the Outcome
Sequence risk is manageable. Here are four strategies:
- Build a 2-to-3-year cash bucket. Set aside $192,000 to $288,000 in T-bills, money markets, or short Treasuries. With the fed funds rate near 4% and the 10-year Treasury near 4.5%, cash finally pays you to wait. When stocks crater, spend the bucket instead of selling equities at the bottom.
- Adopt Guyton-Klinger guardrails. After any year the portfolio falls 20% or more, cut the next year’s withdrawal by 10%. A temporary trim from $96,000 to roughly $86,000 could be the difference between a portfolio that recovers and one that does not.
- Carve out a longevity income floor. A small single-premium immediate annuity (SPIA) or qualified longevity annuity contract (QLAC) starting at 80 or 85 turns part of the portfolio into a guaranteed paycheck. That frees the remaining balance to stay equity-heavy.
- Use a rising equity glidepath. Wade Pfau’s research shows that starting at 60% equity and drifting toward 80% as you clear the danger zone past age 75 improves outcomes. The intuition: early years are when a crash does the most damage, so own less of it then.
What to Do First
Fund the cash bucket. It is the cheapest insurance against down markets that break retirements, and at today’s short rates the opportunity cost is small. Then write down the guardrail plan that you evaluate at the end of each year.
The common mistake is staring at the average return number and not paying attention to the first five years of market performance. If you’re lucky the markets will soar. But if not, there are steps you can take to protect yourself.
