Sequence of Returns Risk: Why the First Five Years of Retirement Matter Most

Picture two Destin couples who retire exactly 5 years apart, with identical one-million-dollar portfolios, identical 4% withdrawal plans, and market returns averaging 7% over 30 years. Same money. Same plan. Same math on a napkin. One couple runs out of money in year 22. The other couple dies with more than $2 million. The only difference is when the bad years showed up.

That is sequence-of-returns risk. It is probably the single most underappreciated danger in retirement income planning, and it is the reason a portfolio that looks fine in a spreadsheet can quietly fail in real life.

What Sequence of Returns Risk Actually Means

While you are saving, the order of returns does not matter much. You are adding money the whole time, so a market drop early in your career is almost a gift. You buy more shares at a lower price, and the long-term average return at the end is what determines your balance.

Once you start withdrawing, the math inverts. Every dollar pulled out during a down year comes from a reduced balance and cannot grow back. If a one-million-dollar portfolio drops 30% in year one to 700,000 and you also pull 40,000 for living expenses, you need close to a 10% return the next year just to get back to 740,000. Add another losing year on top of another withdrawal, and the hole becomes almost impossible to climb out of. The 30-year average return can still look acceptable, but the portfolio is already empty.

Research by Wade Pfau estimates that roughly 77% of a retirement portfolio's outcome is explained by returns in the first 10 years. Industry research, referenced by Morningstar and SmartAsset, finds that negative returns in the first five years account for about 70% of retirement plan failures. The size of the eventual long-term average is far less important than the timing of the early drawdowns.

The Fragile Decade

Advisors call it the retirement risk zone or the fragile decade. It is the five years before and the five years after your retirement date. During that window, your portfolio is at its largest, your withdrawals are starting, and you have the least flexibility to earn your way out of a problem. A bad market in year one of retirement is not the same event as a bad market in year 20. The first is a permanent impairment. The second is a temporary drawdown.

A 65-year-old who retired in 1972 walked straight into the 1973-1974 bear market, when the S&P 500 fell 48%. A retiree in 2000 with one million dollars and a 4% withdrawal plan watched the portfolio fall 40 to 50% by 2002. A 2008 retiree hit a similar wall. In each case, the long-term averages eventually looked fine. The real-world outcomes did not, and the retirees who did not adjust their spending were much more likely to run out of money.

Research from U.S. Bank and Schwab is even blunter. If your portfolio drops at least 15% in year one of retirement and you still pull 3.3%, your odds of running out of money inside 30 years jump by a factor of six compared with someone whose first year is positive.

Four Practical Defenses

The good news is that sequence risk is manageable. Not eliminated. Managed.

Keep a cash or short-bond bucket. Many Emerald Coast retirees hold one to three years of planned withdrawals in cash, money market funds, or very short-duration bonds. If you spend 70,000 a year from the portfolio, that is roughly 140,000 to 210,000 in a stable bucket. When stocks drop, you draw from that bucket and let the equity side recover. It is a shock absorber that buys time. We walk through the mechanics of this in how to build a retirement paycheck.

Use a flexible withdrawal rule. Morningstar's 2025 retirement income research set the safe starting withdrawal rate at 3.9% for a 30-year retirement at a 90% success probability, with updated 2026 work landing in a similar range. The rate is not sacred. Retirees who trim spending 5 to 10% during bad market years, then allow themselves a raise in strong years, dramatically reduce their odds of running out. Spending flexibility is almost always more valuable than portfolio complexity. See our broader framework on retirement distribution planning for how this fits with tax and account-sequencing decisions.

Consider a rising equity glide path. Research by Michael Kitces and Wade Pfau found that starting retirement with a more conservative allocation, say 40 to 50% in equities, and slowly raising the stock allocation over the first 10 to 15 years, can reduce sequence risk. It feels counterintuitive, but the protection shows up right when you need it most, and the equity tilt arrives once the fragile decade is behind you.

Add a guaranteed income floor. Social Security, a pension if you have one, a single premium immediate annuity, or a deferred income annuity can all carry baseline living expenses. Once the "must pay" bills are covered by guaranteed income, the portfolio only funds discretionary spending. A down market becomes a travel cut, not an existential problem.

The Emerald Coast Angle

Northwest Florida is a popular retirement market precisely because the cost of living is manageable and the lifestyle is flexible. That flexibility is an underrated risk management tool. A retiree in Navarre or Gulf Breeze who can cut travel for a year, delay a new vehicle, or shift from a weekly charter fishing habit to pier or surf fishing for a season has more control over a sequence risk problem than a retiree whose fixed costs fill the entire budget. The plans that survive bad early markets are usually the ones built with room to flex. For a broader look at how we approach this locally, see retirement income planning for Destin and 30A.

Veterans with VA disability income and a pension have an advantage here, because guaranteed lifetime payments already cover a larger share of expenses. Business owners who sell a company and roll the proceeds into a portfolio are at the opposite end. The entire retirement balance can arrive on a single closing day, and that balance gets dropped straight into the fragile decade. A staged market entry, combined with a strong cash position, warrants serious consideration.

The Bottom Line

The fragile decade deserves more respect than it gets. A portfolio does not care whether the bad year happens in 2027 or 2047. The retiree does. Design the first 10 years of retirement around that reality, and the plan you built on the spreadsheet has a much better chance of still working when you are 85 and watching the sun set over the Gulf.
