The Retirement Risk Almost Nobody Plans For

Two people retire with the same $1,000,000. They withdraw the same $50,000 a year. Over their retirement, their investments earn the exact same average return, 7%.

One dies with money to spare. The other runs out more than a decade early.

Same starting balance. Same withdrawals. Same average. Wildly different endings.

The difference is the order the returns arrived in. That is sequence of returns risk.

Why People Trust The Average

When you plan for retirement, you reach for one number: the average return. Seven percent a year, the math says you are fine.

And during your working years, that instinct mostly holds. If you are adding money and not touching it, a good or bad early decade washes out over time. The average is roughly what you get.

So people carry that assumption into retirement, where it quietly stops being true.

What Goes Wrong When You Withdraw

Everything changes once you are pulling money out instead of putting it in.

If the market crashes in your first few retirement years, you are forced to sell investments at low prices just to cover your living costs. Those sold shares are gone. They are not around to recover when the market eventually bounces back.

A crash early in retirement does permanent damage. A crash late in retirement, after years of good returns have padded the balance, barely matters. Same drop, completely different outcome, purely because of when it lands.

The reason is that a withdrawal and a market drop stack on top of each other. In a bad year your balance falls and you still pull out your living costs, so the account shrinks from both sides at once. Sell enough shares while prices are low and there are simply fewer left to participate in the recovery. The portfolio never fully heals.

"When you are withdrawing, the order of your returns can matter as much as the average."

What Experienced Retirees Actually Say

The people who study this for a living have a clear message. Defend the first decade of retirement. That window is where the risk concentrates.

During accumulation the effect mildly reverses. An early crash can actually help a regular investor, because their ongoing contributions buy more shares cheaply. That is why the same person who should welcome a downturn at 30 should fear one at 65.

The honest caveat: you cannot control whether your retirement starts in a good year or a bad one. Nobody can. So the answer is not prediction. It is building a plan that survives a bad first few years.

The Practical Answer

You manage sequence risk by softening those first vulnerable years:

• Hold a cash buffer of a year or two of spending, so a crash does not force you to sell stocks.
• Use a bond cushion early in retirement, then let it run down as the danger passes.
• Stay flexible. Trim spending in a bad year instead of withdrawing on autopilot.
• Start with a lower withdrawal rate, around 3.25% to 3.5%, especially for a long retirement.

None of this requires predicting the market. It just makes sure a bad start does not become a permanent wound.

A Worked Example

Back to our two retirees. Same $1,000,000, same $50,000 a year, same 7% average over the full stretch.

The averages are identical. The only thing that changed is when the bad years showed up. That is the whole risk, in one comparison.

Common Mistakes

• Planning your whole retirement on a single average return.
• Withdrawing the same amount rigidly even in a down year.
• Holding 100% stocks at the very start of retirement.
• Keeping no cash buffer, so a crash forces selling at the worst time.
• Assuming what worked during accumulation also works during withdrawal.

Common Questions

Does sequence risk affect me while I am still saving?

Much less, and it can even help. While you are adding money and not withdrawing, an early crash lets your contributions buy cheaper shares. The danger is concentrated in the years you start drawing down.

How long is the danger window?

Roughly the first decade of retirement. A poor sequence in those years does the most lasting damage, because you have the most money exposed and the least time to recover.

Can I just keep all cash to avoid it?

No. Too much cash creates a different problem, inflation slowly eroding your buying power across a long retirement. The aim is a buffer for the early years, not abandoning growth entirely.

What withdrawal rate protects against it?

A lower starting rate helps. Many planners suggest around 3.25% to 3.5% for a long retirement, paired with the willingness to spend less in bad years.

The Bottom Line

The average return is not a promise about any single year, and in retirement the timing of those years is what makes or breaks you.

You cannot choose when the bad years come. You can build a plan that survives them.

Defend the first decade.

Keep a buffer, stay flexible.

The order matters, not just the average.
