Same average return. Opposite endings.
When you’re accumulating wealth, order doesn’t matter — a 30% gain followed by a 10% loss ends the same as a 10% loss followed by a 30% gain. Multiplication commutes. But when you’re withdrawing from a portfolio, every year’s ending balance is also next year’s starting point minus a fixed bill — and suddenly the order becomes everything.
Take $1,000,000. Average return 7% over 30 years. Pull $50,000 a year. Now run it twice — once with the bad years first, once with them last:
Bob and Alice — One Average, Two Retirements
| Sequence | Bob — bad start | Alice — good start |
|---|---|---|
| Years 1–3 | –15%, –10%, –5% | +15%, +10%, +5% |
| Years 4–27 | +9% average | +9% average |
| Years 28–30 | +5%, +5%, +5% | –15%, –10%, –5% |
| Outcome | Portfolio runs dry in year 22 — broke at age 87 | Dies with $1.8M left over — same average, flipped order |
Why it happens — the math. When Bob’s portfolio drops 15% in year one ($850,000 left) and he pulls $50,000 for living expenses ($800,000 left), his recovery starts from a much smaller base. Each subsequent withdrawal is a larger percentage of what remains, so the portfolio has to run faster every year just to stand still. Compounding, the force that built the money, starts working against him on the way down.
Alice hits her big gains early. Her $1,000,000 becomes $1,150,000 after year one; she pulls the same $50,000 and still has $1,100,000. Her withdrawals shrink as a share of the balance every year. Same average, same spending, same thirty years — and the arithmetic of the starting balance decides everything.
It’s not what you earn, it’s what you keep — and for retirees, when you earn it matters even more than how much.
The first five years decide the next twenty-five.
Research from Wade Pfau and Michael Kitces shows that roughly 80% of “ruin risk” concentrates in the first five years of retirement. Survive a bear market in years one through five without dipping heavily into principal, and your 30-year success rate jumps above 90%. Start with a 2000–2002 or 2008-style crash and the math gets ugly fast. History has run this experiment repeatedly:
| Retirement start year | First 5-year market | 30-year, 4%-rule outcome |
|---|---|---|
| 1966 | Crushed (stagflation) | Ran out in year 30 — barely survived |
| 1973 | Two bear markets | Ran out in year 28 — failed |
| 1982 | Start of an 18-year bull | Ended with 4× the starting balance |
| 2000 | Tech bust + ’08 | In danger — depends on the next 5 years |
| 2009 | Bull + ’21 mania | Ended with 3×+ the balance |
Notice what the table does not reward: average returns. The 1966 and 1982 retiree lived through many of the same decades — the difference was which end of the sequence they entered on. You don’t get to choose your cohort. You do get to choose how exposed the first five years are, which is the entire point of the defenses below.
You can’t schedule the bear. You can refuse to sell to it.
Keep the next few years’ spending out of the market.
Hold 2–3 years of living expenses in cash and 5–7 years in bonds, and spend from those buckets when stocks are down. Equities only get touched in up years — so a bear market never forces you to sell at the bottom. This converts the danger-zone problem from “hope the market cooperates” into “wait it out on purpose.”
Cover the essentials with checks that don’t read the newspaper.
Housing, food, healthcare — the non-negotiables — covered by Social Security + pension + annuity, so the portfolio only funds the discretionary layer. When a crash can’t threaten your basics, you can actually leave the equity sleeve alone long enough for it to recover. (When to start the Social Security piece is its own decision — we wrote it up here.)
Trim the paycheck after bad years — briefly, and by plan.
Cut spending 10–15% in the year following a –10%-or-worse market. A small, temporary adjustment made early does more for 30-year survival odds than almost any portfolio change made late — and because it’s written into the plan in advance, it’s a rule you follow, not a panic you improvise.
If you’re retiring 2026–2028
This risk is the one to plan for before the date, not after it — the buckets have to exist on day one, and mid-2026’s record-high prints (S&P 7,126, NASDAQ 24,468) make a drawdown somewhere in your first year or two the statistically ordinary case, not the surprise. Four moves, in order:
Build the bucket before you retire — aim for 2 years of cash plus 5 years of bonds in place at the start. Consider a deferred annuity to cover year-15-and-beyond fixed expenses, which lets the rest of the portfolio carry more equity risk. Write down a spending-cut trigger now — decide today how you’ll respond to a 20% drop, before emotions hijack the plan. And pressure-test the whole thing against the worst historical sequences rather than the average ones.
Sequence risk is the reason two identical savers can have opposite retirements. It can’t be predicted, but it can be neutered: a bucket so bad years aren’t sold, a floor so bad years aren’t frightening, and a written trigger so bad years aren’t improvised. If your plan’s survival depends on the first five years being kind, that isn’t a plan — it’s a cohort lottery ticket.
Stress-test your retirement plan against the worst starts on record.
Fifteen minutes to start. We’ll run your actual numbers through 1,000 Monte Carlo scenarios — including the three historical worst-case sequences (1966, 1973, 2000) — and show you your success probability. Most clients are surprised; better now than in year three.
