Retiring just as the market drops is one of the riskiest things that can happen to a retirement plan — and it has a name: sequence-of-returns risk. The danger is not simply that your portfolio is worth less. It is that withdrawing money from a falling portfolio in the early years does permanent damage, because you are selling investments while they are down, leaving fewer of them to recover when the market eventually rebounds. Two retirees can earn the exact same average return over their retirement, yet one thrives and the other runs out of money — purely because of when the bad years arrived.
The good news: while you cannot control the market, you can absolutely protect yourself against this risk with a few well-known strategies. Below we explain how it works with a simple example, why the early years are so fragile, and what to do about it. You can stress-test your own plan against bad-timing scenarios in the RetireSpan retirement planner.

While you are still working and saving, a market crash is almost a gift — your regular contributions buy shares cheaply, and you have years for them to recover. But once you retire and start withdrawing, that logic flips completely. Now a downturn means you are selling shares at low prices to fund your living expenses, and every dollar you take out during a slump is a dollar that can never recover.
This is why the order of your returns matters so much in retirement, even though it makes no difference at all while you are accumulating. Same average return, opposite outcomes — entirely because of timing and the direction of your cash flow. You can see this dynamic modeled in the app.
Picture two retirees who each start with $1,000,000 and withdraw $50,000 at the end of every year. They experience the exact same three returns — +30%, −10%, and −20% — just in opposite order. Retiree A gets the bad years first; Retiree B gets the good year first.
| Year | Retiree A (bad start) | Retiree B (good start) |
|---|---|---|
| Start | $1,000,000 | $1,000,000 |
| Year 1 | −20% → $750,000 | +30% → $1,250,000 |
| Year 2 | −10% → $625,000 | −10% → $1,075,000 |
| Year 3 | +30% → $762,500 | −20% → $810,000 |
Balances shown are after each year's $50,000 withdrawal. Both retirees had the identical average return and identical withdrawals.
After just three years, Retiree B is ahead by $47,500 — despite identical returns and identical spending. The only difference was timing. Stretch this over a real 30-year retirement with a deeper early downturn, and the gap doesn't stay small: it can become the difference between leaving a comfortable estate and running out of money entirely. You can run your own version of this comparison in the RetireSpan tools.
The mechanism is simple but brutal. When your portfolio is down and you withdraw a fixed dollar amount, that withdrawal represents a bigger percentage of your shrunken balance — so you sell more shares to raise the same cash. Those extra shares are gone for good, which means when the market recovers, you have fewer shares left to recover with. The losses and the withdrawals compound against each other.
In a rising market the opposite happens, which is why a good start is so powerful: early gains build a cushion that lets your portfolio absorb later losses comfortably. The first several years essentially set the trajectory for everything that follows. Understanding that asymmetry is the key to protecting yourself, which the app helps you visualize.
Tip: The same market volatility that helps you while saving can hurt you while withdrawing. The deciding factor is the direction of your cash flow — money flowing in loves a dip, money flowing out fears one.
Sequence-of-returns risk is not equally dangerous throughout retirement. It is concentrated in roughly the five years before and five years after your retirement date — a stretch often called the "fragile decade" or "retirement red zone." This is when your portfolio is largest, your withdrawals are just beginning, and you have the least time to recover from a bad start.
A crash 20 years into retirement is far less threatening, because by then your earlier gains have built a buffer and your remaining horizon is shorter. But a crash right at the start strikes at the most vulnerable moment. Knowing where you sit in that danger zone should shape how you invest as your retirement date approaches — something you can plan around on the RetireSpan landing page.
You cannot control when a downturn hits, but several proven strategies blunt its impact. Keep a cash cushion — 1 to 2 years of expenses — so you can pay bills without selling stocks in a slump; this is the heart of the bucket strategy. Stay flexible with spending, trimming withdrawals modestly in down years so you sell fewer shares at low prices. Ease your stock exposure as you approach retirement, then optionally let it rise again afterward, so you are least exposed during the fragile decade. And delay Social Security or build guaranteed income, which reduces how much you need to withdraw from investments at all. You can model how each of these strengthens your plan in the RetireSpan app.
The most important defense is simply knowing how your plan holds up if the timing goes against you. A Monte Carlo simulation runs your plan through a thousand scenarios — including the unlucky ones where markets fall in your first years — and reports how often you still succeed. If your plan only works when markets cooperate early, that is exactly what you want to discover before you retire, not after. You can run that test on your own plan using the free tools on the landing page.
Don't let bad timing wreck your retirement
RetireSpan stress-tests your plan against down-market scenarios, builds a protective cash bucket, and shows your odds of success — built for people 55–65 who want a plan that survives bad luck, not just good luck. Get it on the App Store or explore features on the RetireSpan website.
Sequence-of-returns risk is the danger that the order of your investment returns — not just their average — harms your retirement, specifically when poor returns arrive early while you are withdrawing money. Selling investments during an early downturn permanently reduces your portfolio's ability to recover. It is one of the biggest threats to a new retiree, and you can test for it in the RetireSpan planner.
Because you are withdrawing money at the same time your portfolio is shrinking, you must sell more shares to fund your spending, and those shares are gone when the market recovers. This combination of losses and withdrawals compounds against you. The same crash later in retirement does far less damage, since by then you have built a cushion.
It can help, because retiring into a downturn exposes you to sequence-of-returns risk at the worst moment, and working a bit longer lets your portfolio recover while you keep earning. However, it depends on your overall plan, cash reserves, and flexibility. Running your scenario through a simulation shows whether delaying meaningfully improves your odds.
Keep 1–2 years of expenses in cash so you avoid selling stocks in a downturn, stay flexible by trimming spending in poor years, ease your stock exposure around your retirement date, and build guaranteed income through Social Security timing. Together these reduce how much you must sell when prices are low. You can model each strategy in RetireSpan.
The retirement danger zone, sometimes called the "fragile decade," is roughly the five years before and five years after you retire. During this period your portfolio is at its largest, your withdrawals are beginning, and you have little time to recover from a bad market, making sequence-of-returns risk most severe. Investing more cautiously through this window helps protect you.
While you are saving, the order does not affect your final balance — only the average matters. But once you are withdrawing in retirement, the order matters enormously: bad returns early can devastate a plan, while good returns early build a lasting cushion, even with the same average. This reversal is the essence of sequence-of-returns risk.
