Most Retirement Plans Are Built for the First 5 Years

Their advisor showed them a plan that looked perfect.

4% withdrawals. Monte Carlo success rate: 87%. Income projection: comfortable for life.

They were 65. They retired confident.

They were 78 when they came to see me. Same portfolio. Same asset allocation. But something had broken.

Their tax bill had nearly doubled. Medicare premiums had spiked by $700 per month. Every withdrawal from their IRA felt wrong; either too much or too little, they couldn’t tell anymore. The plan that felt so solid at 65 had become rigid and expensive by 78.

“What changed?” they asked.

Nothing changed. The plan just wasn’t built for year 13.

Here’s the uncomfortable truth about most retirement plans: they’re stress-tested for the transition, not the duration.

Advisors focus intensely on the first five years. Can you survive an early market crash? Will you panic and sell? Can the portfolio handle sequence-of-returns risk?

These are real concerns. But they dominate the conversation so completely that we end up ignoring what happens later.

Most retirement plans ask: “Can you retire?”

Very few ask: “Can you stay retired?”

Retirement isn’t a moment; it’s a multi-decade system. And most plans quietly begin to unravel in years 10, 15, and 20, not year 2.

Let me show you why the first five years get all the attention.

Everyone fears the first market crash. That’s why early retirement planning obsesses over sequence-of-returns risk, the possibility that a downturn in years 1-3 permanently damages your portfolio. If you retire in 2008 and have to sell stocks at the bottom to cover expenses, your portfolio never fully recovers. Same investments, different timing, catastrophic outcome.

There’s also the emotional shock of stopping work. Identity and income both change overnight. Advisors want early stability to prevent panic because they know that a shaky start can derail even a well-funded retirement.

These risks are real. I’m not dismissing them. But while advisors stress-test for early volatility, they rarely model what happens at 73 when required minimum distributions spike your income by 40%. They don’t ask what happens when one spouse dies and tax brackets compress. They don’t plan for what happens at 85 when managing a complex portfolio becomes cognitively overwhelming.

That’s where most plans quietly fail. Not in year 2. In year 15. In year 23.

Let me show you exactly what breaks, and when.

The RMD Creep (Ages 73+)

Here’s the pattern I see constantly:

A couple retires at 65 with $1.2 million in their traditional IRA. They’re in the 22% tax bracket. The plan shows comfortable withdrawals, reasonable taxes, and everything balanced.

But nobody does Roth conversions during the gap years (ages 65 to 72) when income is low, and tax rates are manageable. The IRA just sits there growing.

At 73, required minimum distributions begin.

Year 1: RMD is $48,000. Year 5: RMD is $58,000. Year 10: RMD is $72,000.

This income isn’t optional; it’s required whether you need it or not.

Suddenly, their taxable income jumps from $65,000 to $95,000. They’re pushed into the 24% bracket. Medicare IRMAA surcharges kick in—$700 per month extra, $8,400 per year. More of their Social Security gets taxed. The withdrawals trigger capital gains they didn’t plan for.

The plan that looked tax-efficient at 66 looks bloated and rigid at 78. Nobody modeled this because most plans are built to survive the first bear market, not the first RMD.

The Widow/Widower Tax Trap

Here’s another pattern that catches people completely off-guard:

Married couple, both 75. Filing jointly. Combined income: $85,000 per year. They’re in the 12% bracket on most of their income. Everything is comfortable and manageable.

Then, one spouse dies. Now the survivor files single. He or she has the same income and same expenses, but the tax brackets just compressed. Imagine the first tax season after losing a partner, sitting down to face the reality of a single-filer return. The change isn’t just emotional; it’s financial shock.

For married filing jointly, the 22% bracket starts at $89,075. For single filers, the 22% bracket starts at $44,725. The same $85,000 income that was mostly taxed at 12% is now partly taxed at 22% and 24%.

The survivor’s effective tax rate jumps from 14% to 19%. That’s $4,250 more in federal taxes every year. Plus, IRMAA thresholds compress too: single filers hit Medicare surcharges at half the income of married couples.

This isn’t a fringe scenario. One spouse dying is statistically likely, and most retirement plans never model the tax impact of that transition.

Longevity Drift

Here’s what people underestimate: how long retirement actually lasts.

At 65, there’s a 50% chance that at least one spouse lives into their early 90s, and a 25% chance of living past 95. That means retirement could last 30 years or more. But most plans are stress-tested for 20.

In year 20 of retirement (when you’re 85 or so), everything gets harder: healthcare costs increase, cognitive decline becomes a real risk, and managing a portfolio that requires constant tactical adjustments, withdrawal optimization, and active rebalancing becomes a burden. Let me illustrate this with a small anecdote: One of my clients, at 85, began mis-sorting account statements and repeatedly called to verify routine financial transactions. These seemingly minor errors quickly compounded, making financial management increasingly overwhelming.

If your retirement plan requires you to be sharp, engaged, and make sophisticated financial decisions at 87, it’s not a robust plan. It’s a plan that assumes you stay mentally acute until you die.

That’s not realistic, and it’s not fair.

Inflation Compounding Quietly

Even modest inflation—3% annually—doubles expenses in roughly 24 years.

At 65, you need $75,000 per year to live comfortably. By 89, this doubles to $150,000 annually just to maintain the same standard of living. To put this into perspective, that additional $75,000 could translate to two extra years of assisted living fees or cover unforeseen healthcare expenses you might encounter as you age.

If your retirement income barely clears expenses in the early years, you have no margin for error later. The plan that felt “comfortable” at 65 becomes fragile at 80.

And here’s the cruel part: inflation hits hardest on the things retirees can’t avoid. Healthcare. Housing maintenance. Long-term care. These don’t inflate at 3%. They inflate at 5-7%.

The early years of retirement may look smooth. But beneath the surface, the system is slowly thinning. By the time you realize it, you’re too far in to restructure.

Now, let me show you what people actually fear because it’s not what most advisors think. Most retirees don’t fear market crashes; they fear living too long. Becoming dependent. Losing control. Running out quietly at 88. This is what I call ‘Long-Tail Frugality Syndrome,’ a term capturing the reality of longevity anxiety. It rarely shows up in spreadsheets; instead, it reveals itself through behavior: Underspending. Hoarding cash. Avoiding travel. Canceling plans. Living smaller than necessary.

Think about one dream experience you’ve been postponing—what safeguards would make you feel free to book it now? This is where a retirement plan should serve as a gateway to living fully, enabling financial freedom rather than imposing limits.

I’ve seen clients with $2 million who won’t book a $3,000 trip because “what if we need it later?” That’s not a portfolio problem. That’s a plan problem.

A well-designed retirement plan doesn’t just preserve assets; it also helps you achieve your financial goals. It restores permission to live. But when the plan is fragile—when taxes are unpredictable, when income depends entirely on portfolio performance, when every market drop threatens the structure—permission disappears.

People don’t live freely when they’re terrified of outliving their money.

And most retirement plans, because they focus so heavily on early sequence risk, never address the quiet fear that dominates the second and third decades: “Will this actually last?”

The core mistake most retirement plans don’t address is the difference between transition planning, which covers the first five years of retirement, and duration planning, which encompasses the rest of your life, however long that may be. Imagine the transition phase as “launching the rocket”—a critical period that determines the trajectory of your retirement. Once launched, you shift to “keeping it in orbit,” a duration planning phase that ensures steadiness and consistency throughout your remaining years. Most retirement plans are designed for transition. They answer: “Can you afford to retire?” Very few are designed for duration. They don’t answer: “What happens in year 15?”

Transition planning focuses on:

• Initial withdrawal rates
• Asset allocation for early volatility
• Surviving the first market crash

Duration planning focuses on:

• Tax sequencing over 30 years
• Income structure that doesn’t depend on portfolio cooperation
• Surviving widowhood
• Cognitive decline in late retirementRMD management before RMDs start

Retirement is not a five-year event; it’s a 30-year engineering problem. And most plans treat it like the former while pretending to solve for the latter.

The couple sitting across from me at 78 didn’t have a bad advisor. They didn’t make reckless decisions. They didn’t overspend. Their plan was just built for the wrong timeframe.

It was optimized to survive years 1-5. Nobody asked what would happen at 73 when RMDs started. Nobody modeled what would happen when one of them died. Nobody planned for the fact that at 85, managing a complex portfolio would feel overwhelming.

The plan worked perfectly for five years. After that, they were improvising. And improvising in retirement is expensive. Because by the time you realize the structure is wrong, most of your options are gone.

So here’s the question worth asking:

Is your retirement plan built for the transition, or for the duration?

Can it handle not just the first market crash, but the RMDs that start at 73? Not just early volatility, but the widow tax trap at 78? Not just the next five years, but the next 25?

Most plans can’t. Not because the math is wrong, but because the timeframe is too short.

Next week, I’ll show you what a plan built for 30 years actually looks like. Not the theory, but the structure.

The three-layer system that separates income from growth, flattens lifetime taxes, and removes the need to depend on markets cooperating at exactly the right time.

Because retirement doesn’t fail in year 2, it fails in year 15, when the plan that felt so solid at the beginning turns out to have been built for a retirement that ended a decade ago.

How many years into retirement are you? Reply and let me know—I'm curious whether the 'years 10-25' risks feel immediate or still distant.
