You have run the numbers, probably more than once. The savings are there, the spreadsheet says the plan holds, and you have picked a date to walk out the door. And still, late at night, a different thought arrives: what if the market comes apart the very year you finally stop working. Not in some distant decade you can shrug off, but right at the start, while the paycheck has just gone quiet and the whole balance is suddenly all you have.
That worry is sharper than it looks, and it is pointed at the right year. Whether your money lasts depends less on the average return you earn over thirty years than on the order those returns happen to arrive in, and above all on what the market does in your first decade out.1 You cannot pick that order. What you may not know yet is how much you can do about how much it is allowed to matter.
What it actually is
Picture two versions of your own retirement, started the same year with the same savings, invested the same way. Over thirty years, both earn the exact same average return. In one, the early years are kind and the rough patch comes late; you die with money to spare. In the other, the rough patch comes first, in the years you have just begun drawing on the money; you run short at eighty-five. Same returns, same average, opposite endings. The only thing that changed was where the bad years fell.
That is sequence-of-returns risk: the danger that the timing of your returns, not just their size, works against you.1 And the reason it bites is plain enough to feel. When the market falls and you are also selling investments to live, you turn a paper loss into a permanent one. The shares you sell near the bottom are gone, and they are not there to recover when the market comes back. Do that in your first years out, while the balance is still near its peak and each withdrawal is a meaningful slice of a shrinking portfolio, and the harm follows you for the rest of your life. The same drop, met twenty years later after good years have built a cushion, barely leaves a mark.
Why it barely matters until you retire
Here is the part that catches people off guard, and it is the reason this risk hid from you for forty years. While you were working and saving, if you simply bought and held and never pulled a dollar out, the order of your returns did not matter at all. The same set of yearly returns lands you in exactly the same place no matter what order they come in. Shuffle them however you like; the final number is identical.2
The order only starts to matter the moment money is moving in or out. Through your working life it worked quietly, and mostly in your favor over a long career, so you never had cause to think about it. The day you retire and start withdrawing, it flips and turns sharp. Now a bad year early, while you are selling into it, does lasting damage, and a good year early builds a cushion that protects everything after. You spent decades in a world where the order hardly mattered. Retirement drops you into one where it can matter more than the average, and no one hands you the new rules on the way out.
The first decade is the danger zone
This is why your first five to ten years carry far more weight than any years that follow.1 It is the stretch when your portfolio is largest, your withdrawals have only just begun, and a bad market has the least time to be undone. A rough start you have planned for is something you ride out. A rough start you have not can force a permanent cut years on, the kind that quietly resets the life you pictured: the second home you do not buy, the trip with the grandchildren you keep postponing, the year you realize the income you built the whole plan around is simply smaller now, and likely to stay that way.
It takes a moment to trust this, because it runs against the grain. Most people brace for the crash deep in retirement, when the balance is smaller and a loss feels larger. The crash that does the most damage is the one that meets you on the way in, in the years you are least braced for it.
The more dangerous crash is not the one deep in retirement. It is the one that greets you on the way in.
What you cannot control, and what you can
You cannot control the order. No one can tell you whether the decade you retire into will be generous or unkind, and anyone who says they can is guessing with your money. The good news, and it is real, is that the order is not the part you have to manage. What you can manage is how exposed you are to it.
What does the damage is being forced to sell stocks into a falling market because that is where this month's income has to come from. What prevents it is arranging, well before you need to, never to be in that position. Three habits do most of that work, and the point of all three is the same: to put time between you and any need to sell at the wrong moment.
The first is a buffer. Keeping a few years of spending, often one to three, in cash and short-term, high-quality bonds means a bad market does not reach into your stocks at the worst moment.5 You live off the buffer, give the stock side time to recover, and refill it in better years. It is the difference between watching a down market with your morning coffee and watching it while doing arithmetic on what you have to sell this week.
The second is flexibility. A plan that spends a fixed amount no matter what is brittle. A plan where you can trim a little after a bad year, hold off on the kitchen remodel, take the closer trip this once, bends instead of breaking, and gives the portfolio room to heal. The trims are rarely painful. They are mostly the difference between a want this year and the same want a year later.
The third is an income floor. To the extent Social Security and any pension already cover what you actually need to live on, a bad early decade becomes an inconvenience instead of a threat, because the market is paying for your wants, not your groceries and your property tax. Some researchers go a step further and suggest starting retirement with less in stocks and adding back over time, so your lightest exposure lines up with your most dangerous years.6 That is one approach among several, and the right mix belongs in your own plan.
When sequence risk matters less
None of this means everyone is equally exposed, and you may be less exposed than you fear. If guaranteed income already covers your essentials, or you are drawing only a small slice of your savings each year, a bad opening decade is uncomfortable but not dangerous to you. The households most at risk are the ones pulling a high share of their spending from the portfolio in the first years, with little room to cut back. The closer that is to your own situation, the more these habits are worth putting in place before you retire, not after.
What it comes down to
You do not get to choose the decade you retire into. You can only choose how much that decade is allowed to matter to you. The plans that last are not the ones that guessed the market right. They are the ones built so the order never had to be guessed at all.
The people who sleep through a bad market are rarely the ones who saw it coming. They are the ones who decided, years earlier, that no falling market would ever get to dictate what they sold or when. That decision is quiet, it is made long before it is tested, and it is most of what separates a scare from a setback.

Common questions
What is sequence-of-returns risk in plain terms? It is the risk that the order of your investment returns, not just the average, decides whether your money lasts. Bad years early in retirement, while you are withdrawing, do far more damage than the same years later, because you are selling into the decline and locking in the losses.1
Why does the order not matter while I am still working? Because if you are not withdrawing, the math does not care about order: the same set of returns produces the same ending balance regardless of sequence.2 Once you start taking money out, the order interacts with those withdrawals, and early losses become permanent.
How big should a cash buffer be? There is no single answer, but a common approach is one to three years of planned withdrawals held in cash and short-term, high-quality bonds, enough to ride out a typical downturn without selling stocks.5 The right size depends on your other income and your spending.
Can I just avoid it by getting more conservative? Holding too little in stocks creates its own problem over a long retirement, because inflation slowly erodes a portfolio that is not growing. The goal is not to avoid risk but to arrange your income so a bad early stretch does not force a sale at the worst time.
