Two retirees can earn the same average return and end up worlds apart — based purely on the order those returns arrived. Here's the risk, in plain English, and how to defend against it.
The short version: Two retirees can earn the exact same average return over 30 years and end up in completely different places — one comfortable, one out of money — purely based on the order those returns arrived. A bad market in your first retirement years does far more damage than the same crash later. This is sequence-of-returns risk, and it’s the danger most people never hear about. We are not financial advisors.
While you're saving, the order of your investment returns barely matters — you're adding money, and over decades it averages out. But the moment you retire and start withdrawing, the order suddenly matters enormously.
Here's why: when you take money out during a downturn, you're selling investments at low prices to cover your spending. Those shares are gone — they can't recover when the market rebounds. A bad first few years digs a hole the portfolio may never climb out of, even if the average return over your whole retirement looks fine.
Imagine two retirees, each starting with the same nest egg, each withdrawing the same amount, each earning the same average return over time. The only difference is timing:
| Retiree A | Retiree B | |
|---|---|---|
| First few years | Strong market | Sharp downturn |
| Later years | Downturn | Strong market |
| 30-year average return | Identical | Identical |
| Outcome | Portfolio thrives | Portfolio can run dry |
Same math on paper, very different lives. Retiree B was simply unlucky enough to retire into a bad market — and withdrawing during that early slump did permanent damage. That's the risk in a nutshell.
You can't control when markets fall, but you can blunt the damage. The common defenses:
Sequence risk is concentrated in the years right around your retirement date — roughly the five years before and the first ten after. Survive that window without selling deeply into a crash, and the math tilts back in your favor. It's why the transition into retirement deserves the most careful planning of all.

Sequence-of-returns risk is the quiet reason two people with the "same" plan can end up worlds apart. The threat isn't the average return — it's a bad market arriving early, while you're withdrawing.
You can't avoid market timing luck, but you can prepare for it: hold a cash cushion, stay flexible with spending in down years, and treat the decade around your retirement date as the high-stakes window it is. That preparation is what turns "unlucky timing" from a catastrophe into a manageable bump.
