The 7 Dangers of Decumulation: Why the Descent Is the Most Dangerous Phase of Retirement

By Rodney Cummings, RSSA® | Legacy Wealth Services

Here’s a fact that stops most pre-retirees cold when I share it with them: 80% of Everest fatalities happen on the descent — not the climb.

Climbers train for years to reach the summit. They obsess over the ascent. And then, exhausted, oxygen-depleted, and emotionally spent after achieving their goal, they face the most dangerous part of the journey: getting back down.

Retirement is identical.

You spent 30 or 40 years climbing — saving, investing, contributing to your 401(k), watching your balance grow. You reached the summit. You retired.

Now comes the descent. And most people are completely unprepared for it.

Why the Descent Is Harder Than the Climb

During your accumulation years, time is your greatest asset. A market crash at 42 is a buying opportunity. You have 20+ years to recover. The math is forgiving.

In retirement, the math flips completely.

When you’re withdrawing income — selling investments to pay your bills — a bad year isn’t just an inconvenience. It’s catastrophic. Here’s why:

Imagine two retirees, both with $500,000 and both averaging 6% annual returns over 20 years. The only difference: one experiences heavy losses in years 1–5, the other experiences them in years 16–20.

Retiree A (losses early): runs out of money at 82.
Retiree B (losses late): leaves $400,000 to their heirs.

Same average return. Completely different outcome. This is called sequence of returns risk — and it’s the single most underestimated danger in retirement planning.

The 7 Dangers of Decumulation

After working with hundreds of retirees across 26 states, I’ve identified seven distinct threats that emerge during the decumulation phase. Most retirement plans — 401(k)s, investment portfolios, generic financial plans — address none of them adequately.

Danger 1: Longevity Risk — Outliving Your Money

A 65-year-old couple today has a 50% chance that at least one spouse will live past 92. A 25% chance one reaches 97.

Yet most retirement plans are built to last 20 years. That’s a problem when you might need 30.

The question isn’t whether your retirement plan looks good on paper at 65. The question is whether it still works at 88.

The fix: Guaranteed lifetime income that pays regardless of how long you live — even if the underlying account balance hits zero.

Danger 2: Sequence of Returns Risk — The Crash You Can’t Recover From

As described above, the order of returns matters enormously when you’re withdrawing income.

The S&P 500 has experienced 8 corrections of 20% or more since 1980. If one of those happens in year 1 or 2 of your retirement, and you’re withdrawing 4–5% annually to live on, the math can permanently derail your plan.

Consider: if your $600,000 portfolio drops to $432,000 (-28%) in year 1, and you withdrew $24,000 to live on during that year, you’re now at $408,000. You need those shares to increase by 47% just to get back to $600,000 — while continuing to draw income.

The fix: Guaranteed income means you never have to sell investments at the worst time. Your portfolio stays invested, has time to recover, and you live on your guaranteed income floor in the meantime.

Danger 3: Healthcare Cost Shock

The average couple retiring today will spend $315,000 on healthcare costs in retirement (Fidelity, 2024 data). That number doesn’t include long-term care.

Long-term care costs — nursing home, assisted living, memory care — average $108,000 per year for a private room. And the average care need lasts 2.5 years, with 20% of seniors needing more than 5 years of care.

Without a dedicated income stream, these costs can devastate a retirement portfolio in 3–5 years.

The fix: A guaranteed monthly income stream that covers essential expenses — including healthcare — regardless of what the market is doing.

Danger 4: Market Volatility

The 2008 financial crisis. The 2020 COVID crash. The 2022 bear market. Each one was a “once in a generation” event — until the next one.

For a working-age investor, volatility is tolerable. For a retiree withdrawing 4–5% annually from a declining portfolio, it’s potentially ruinous.

Without principal protection, every market correction forces a binary choice: (1) sell at the bottom to fund your lifestyle, or (2) dramatically cut your spending.

Neither is acceptable when you’ve spent 40 years building toward a certain retirement vision.

The fix: Fixed Index Annuities participate in market upside (via index-linked interest crediting) with a 0% floor on principal. You capture gains. You never absorb losses. The descent happens — but you’re not on the mountain when it does.

Danger 5: Tax Exposure — The Tax Time Bomb

Traditional IRA and 401(k) balances are fully taxable on withdrawal. You’ve been tax-deferred for decades — but the bill is coming.

Required Minimum Distributions (RMDs) kick in at age 73. For many retirees, RMDs from a $800,000–$1,200,000 IRA generate $32,000–$48,000+ in taxable income per year — on top of Social Security benefits.

This can push retirees into higher tax brackets than they experienced during their working years, and in some cases trigger the Social Security “taxation threshold” (85% of SS benefits become taxable).

Nobody warns them about this during the accumulation phase.

The fix: Non-qualified (after-tax) annuities grow tax-deferred and aren’t subject to RMD rules. Strategic placement of assets between qualified and non-qualified accounts can significantly reduce lifetime tax exposure in retirement.

Danger 6: Inflation Erosion — The Slow Thief

At 3% annual inflation, your purchasing power is cut in half in 24 years.

A $4,000/month income today feels like $2,000/month in 2050. If you retire at 65 and live to 90, you’ve experienced 25 years of purchasing-power erosion on every fixed income source in your plan.

This is particularly devastating for retirees who rely heavily on fixed pension payments, fixed annuity income without inflation riders, or cash accounts.

The fix: Index-linked growth inside a Fixed Index Annuity means your accumulation value keeps pace with market performance. Many income riders also include cost-of-living adjustment options to help income grow over time.

Danger 7: Spending Paralysis — The Hidden Danger Nobody Talks About

This one surprises people. The danger isn’t just running out of money — it’s being so afraid of running out of money that you never actually enjoy your retirement.

I see it constantly. Retirees with $800,000 in the bank who are afraid to take the vacation they’ve planned for 20 years. Grandparents who scrimp on gifts because they don’t know if their portfolio will last. People living below their means on money they worked 40 years to accumulate.

The irony is that most of them have “enough” — they just don’t have a guaranteed income floor that gives them permission to spend.

The fix: When your essential monthly expenses — housing, food, utilities, healthcare, insurance — are covered by guaranteed income you cannot outlive, you can spend discretionary money freely, without guilt or fear. The guaranteed income is the foundation that makes the rest of retirement actually enjoyable.

What a “Descent-Proof” Retirement Looks Like

The most resilient retirement income plans I build share a common structure. I call it the Paychecks & Playchecks framework:

Paychecks cover the non-negotiables — your essential monthly expenses. These come from sources that are guaranteed regardless of what markets do:

Social Security (optimized via RSSA® analysis)
Fixed Index Annuity with lifetime income rider
Pension (if available)

Playchecks cover everything discretionary — travel, dining, hobbies, family. These come from:

Investment portfolio (IRA, brokerage)
Part-time income
Remaining annuity withdrawals

When your Paychecks cover your essentials, your Playchecks are completely guilt-free. And your investment portfolio — freed from the pressure of funding your lifestyle during downturns — can stay invested and grow.

This is how the wealthy have always structured retirement income. It’s not complicated. It’s just not what most people are taught.

One of the most powerful strategies I use with pre-retirees involves combining a Fixed Index Annuity with a delayed Social Security claim.

Here’s how it works:

You retire at 62. Instead of claiming Social Security early (which permanently reduces your benefit), you activate the income rider on your FIA.
The FIA provides guaranteed income — say, $2,400/month — as “bridge income” from age 62 to 70.
Meanwhile, your Social Security benefit grows at 8% per year from age 62 to 70.
At 70, you claim Social Security. Your benefit is 76% higher than it would have been at 62.
At 70+, you now have two permanent, guaranteed income streams: Social Security + FIA income. Neither can run out.

The difference between claiming Social Security at 62 versus 70 is often $100,000–$200,000 in additional lifetime income. For many clients, this single decision — combined with the right annuity bridge — is the most valuable financial move of their entire retirement.

As an RSSA® (Registered Social Security Analyst), I run detailed personalized analyses for every client to find their optimal claiming age.

The 5 Myths That Lead People to the Descent Unprepared

Before we close, I want to address the five biggest misconceptions I hear from pre-retirees — beliefs that leave them dangerously exposed:

Myth 1: “The 4% rule will fund my retirement.” The 4% rule was developed in 1994 using historical bond yields and equity returns from a very different environment. It fails in roughly 5% of scenarios — and in a high-inflation, low-yield environment, that failure rate rises. It was never designed to be a guaranteed income strategy.

Myth 2: “I’ll spend less in retirement.” The early years of retirement — the “Go-Go Years” — often cost more than working years. Travel, home improvements, dining, family events. Most retirees I work with spend close to 100% of their working income in years 1–10 of retirement.

Myth 3: “My portfolio is big enough — I don’t need an annuity.” Guaranteed income isn’t just for people with small portfolios. The wealthiest retirees use it specifically because they have big portfolios — and they can’t afford to watch them get cut in half in year 2 of retirement while they’re withdrawing income.

Myth 4: “Annuities are full of fees and hard to understand.” That reputation belongs to variable annuities sold by brokerages in the 1990s. Fixed Index Annuities have no annual investment management fees, no sub-account charges, and transparent surrender schedules. The criticism is 30 years out of date.

Myth 5: “I’ll figure out income planning when I retire.” The best time to lock in guaranteed income is before you need it — when you’re healthy, have full access to products, and rates are favorable. Every year you wait, your options narrow. Procrastination is the most expensive decision most retirees make.
