Most people think the biggest retirement risk shows up late, the fear of running out of money in your eighties or nineties.

However, the conditions that create that risk usually show up much earlier.

The first five years of retirement are a genuine hinge point. Your paycheck stops, withdrawals begin, and decisions about Social Security, taxes, healthcare, investments, and spending all start colliding with one another in ways they never did while you were working.

Those five years don’t literally dictate everything that follows. Still, they have an outsized effect on how much flexibility your plan keeps for the twenty that come after.

That’s why retirement shouldn’t start with a portfolio balance and a withdrawal percentage. Instead, it should start with a plan for the stretch when your financial life is most exposed to change.

Retirement Changes the Math

While you’re working, a market decline is uncomfortable, but it’s survivable. You’re still earning, still contributing, and you have time to let markets recover.

Retirement rewrites that equation.

Once withdrawals begin, your portfolio has to absorb two things at once, the market’s swings and the money you’re pulling out to live on. As a result, a decline in the first year or two can do far more damage than the same decline fifteen or twenty years later.

That’s sequence-of-returns risk.

Two retirees can earn the exact same average return over their retirement and still end up in completely different places, depending on when their best and worst years land. In fact, the decumulation research keeps showing the same thing, that losses early in retirement, paired with ongoing withdrawals, can meaningfully shorten how long a portfolio lasts.

In other words, the average return in your projection doesn’t tell the whole story. The order of those returns does.

Why an Early Loss Is So Hard to Recover From

Say you retire with $3 million and plan to draw $150,000 in your first year.

If the portfolio drops 20 percent before you take anything out, it falls to about $2.4 million. After that first $150,000 withdrawal, you’re at roughly $2.25 million.

Now the portfolio has to recover from the loss and keep funding every withdrawal that follows.

By contrast, put that same 20 percent decline in year twenty, and the picture changes. By then you may have banked years of positive returns, shortened the horizon the money has to cover, or adjusted your spending. The drop still stings, but the plan is built to take it.

That’s why, in our planning work, we don’t just ask whether a portfolio can support a given withdrawal over thirty years. We also ask what happens if the bad years show up first.

What if the market falls in year one?

What if inflation stays hot?

What if the roof, the car, and a round of dental work all land in the same twelve months?

What if a large Roth conversion quietly triggers a Medicare premium increase?

A good plan answers those questions before you’re forced to answer them in real time, under pressure.

The First Five Years Are About More Than Markets

Sequence risk matters, but markets are only half the story.

The early years of retirement are also when the big, hard-to-reverse decisions get made.

For example, take Social Security. Benefits generally grow for each year you delay claiming past full retirement age, up to age 70. That doesn’t make delaying right for everyone, health, marital status, survivor needs, other income, and your withdrawal strategy all weigh in. However, once you claim, your options narrow.

Similarly, consider the window between retiring and the start of required minimum distributions. Your earned income may be lower in those years, which can open room for Roth conversions, capital-gain harvesting, charitable planning, or deliberate withdrawals from tax-deferred accounts. Under current rules, most retirees begin RMDs at age 73, though the exact age depends on your birth year.

Here’s where it all ties together, and where a lot of plans go wrong. A Roth conversion can’t be judged only by comparing today’s tax rate to a future one. Higher income in a single year can raise your Medicare Part B and Part D premiums through IRMAA, pull more of your capital gains into tax, and reshape the tax bill your surviving spouse will one day face. These moves live in the same retirement tax window I’ve written about before, so I won’t rebuild that case here.

The problem isn’t that retirees make these decisions. Instead, it’s that they too often make them one at a time, when the entire point is to coordinate them.

Two Couples, One Market, Two Outcomes

Picture two couples. Each retires at 65 with $3 million and needs about $150,000 a year to live the life they’ve planned for. In their first three years, both run into the same rough market.

The first couple keeps taking the full, inflation-adjusted withdrawal straight from the portfolio. They claim Social Security right away, because watching their investments fall makes them nervous. And they go ahead with a big travel year and a major renovation.

No single one of those choices is unreasonable. However, stacked together, in a down market, they pile pressure on a portfolio that’s already shrinking.

The second couple runs a different play. They lean on a near-term cash reserve, so they’re not selling growth investments into the decline. They separate essential spending from discretionary, and push part of the travel budget out a year. They rebalance back to their policy instead of reacting to the headlines. Finally, they revisit Social Security and Roth conversions in light of the new market and tax picture.

Same returns. Different retirement. The difference wasn’t the market, it was the decisions they made around it.

The point isn’t that every retiree needs that exact reserve or withdrawal order. Instead, it’s that retirement resilience comes from having more than one way to respond.

Flexibility Might Be Your Most Valuable Retirement Asset

In planning conversations, I keep coming back to one distinction, the line between essential spending and flexible spending.

Essential is housing, food, insurance, healthcare, taxes, basic transportation. You can’t cut those quickly.

Flexible is travel, gifts, renovations, the vehicle upgrade, the discretionary purchases. Those matter too, retirement is meant to be enjoyed, not endured. However, having some room to shift their timing can keep a temporary market drop from hardening into a permanent setback.

The withdrawal research backs this up. Dynamic strategies that adjust spending when the portfolio moves outside preset guardrails tend to hold up better than mechanically raising withdrawals every year, no matter what markets are doing.

That doesn’t mean slashing spending every time the market has a bad month. Instead, it means deciding in advance what would actually trigger a change. For example, ordinary spending might continue through normal volatility, while the big discretionary items get a second look if the portfolio falls past a line you set ahead of time.

The value is in making that call while everyone’s calm, not after fear has taken the wheel.

A Five-Year Retirement Stress Test

Before you retire, you want to know the plan can handle more than the expected case. Five tests get you most of the way there.

Test an early market decline

Instead of assuming smooth average returns, model a real drop in year one or two. Then map out exactly how you’d fund spending without abandoning your long-term strategy, whether that’s cash, short-term fixed income, trimmed discretionary spending, or another income source. “We’ll figure it out when it happens” isn’t a strategy.

Separate recurring and irregular spending

A monthly budget is necessary but not sufficient. Roofs, cars, family support, big trips, and uncovered healthcare arrive in lumps, and they belong in the model separately from ordinary lifestyle spending. Otherwise, a plan can look sustainable while quietly ignoring the retirement spending blind spot most likely to derail it.

Build a multiyear tax map

Retirement tax planning shouldn’t be done one April at a time. Instead, project your income out through the start of RMDs and beyond, find the years when taxable income dips, and test whether Roth conversions or other moves improve your lifetime tax position, not just this year’s return. Then check how each move ripples into IRMAA, capital gains, charitable goals, and your surviving spouse.

Name the permanent decisions

Social Security claiming, pension elections, selling the house, large gifts, certain insurance choices. Some of these can’t be undone. Before you act, get clear on what’s reversible and what isn’t. When uncertainty is high, keeping your options open is often worth more than locking in a permanent answer early.

Set your guardrails

Finally, decide ahead of time how the plan responds when things move. What happens if spending runs 10 percent over plan? If the portfolio drops? If one spouse dies earlier than expected? If a child needs help? If you want a second home? A plan is far more useful when it holds decision rules, not just projections.

The Goal Isn’t to Predict the First Five Years

Nobody knows what markets, inflation, tax law, healthcare, or your family will do in your first five years of retirement.

Fortunately, a strong retirement plan never required a crystal ball. It requires preparation.

Those first five years matter because that’s when withdrawals begin, the big elections get made, and the portfolio has the least room for an avoidable mistake. However, they don’t have to dictate the rest of your retirement. A coordinated plan gives you room to respond, through appropriate reserves, flexibility in your discretionary spending, coordinated tax decisions, a disciplined portfolio, and a plan you actually revisit as life changes.

So before you circle a retirement date, don’t ask only whether you’ve saved enough. Ask whether the plan can survive an unfavorable start.

Because the strength of a retirement plan isn’t how well it works when everything goes right. It’s how much flexibility you’ve still got when something goes wrong. That’s where clarity, confidence, and peace of mind actually come from.

If you’d like to pressure-test your own first five years, especially how your withdrawals, Social Security timing, and Roth conversions interact before the difficult years get a vote, that’s the conversation we have every day. We’d be glad to have it with you.
