Key Takeaways
- Retirement planning changes as clients move from accumulation to decumulation. The focus shifts from how much they can save to how much they can safely withdraw.

- Many retirees are hesitant to spend from investment assets, even when their savings may support higher withdrawals.
- Guaranteed income, including income from annuities, can help give retirees a “license to spend” by making a portion of retirement income feel more predictable and dependable.2
What is retirement decumulation?
Retirement decumulation is the process of converting savings into income during retirement. While accumulation focuses on building assets, decumulation focuses on how those assets are withdrawn to support spending, lifestyle needs, and long-term financial security.
For decades, much of the retirement industry has centered on accumulation:
How much clients should save, how they should invest, and whether they are on track to reach a target number.
Those questions still matter. But for clients approaching or entering retirement, the question often changes from “How much have I saved?” to “How much can I safely withdraw?”
That shift is especially important during the current Peak 65 demographic wave, with more than 4.1 million Americans turning 65 each year through 2027, or more than 11,200 people every day.1
This means millions of households are trying to turn savings into dependable retirement income.
Why do retirees struggle to spend their savings?
Many retirees struggle to spend because retirement changes the emotional meaning of money. During working years, account balances can represent progress, security, and discipline. In retirement, drawing down those same balances can feel like losing ground.
The challenge isn’t purely logical. It is behavioral.
Research from David Blanchett and Michael Finke suggests many retirees spend less from savings than common retirement models would imply.
In one analysis, withdrawal rates from savings were approximately 2.1% for 65-year-old married households and 1.9% for single households.2
That is well below the general withdrawal-rate assumptions often used in retirement planning.
This cautious behavior is understandable. Retirees may worry about market downturns, healthcare costs, inflation, longevity, or becoming a burden to family.
Even clients who appear financially prepared may hesitate to spend because they do not know how long their assets need to last.
How can annuities help create a “license to spend”?
Annuities may help reframe retirement assets from a balance clients feel they need to preserve into income they can count on.
Blanchett and Finke’s research on retirement spending behavior found that retirees tend to spend more from wealth held in the form of lifetime income than from non-annuitized investment assets.
Their research also found that approximately 80% of lifetime income is spent by retirees, compared with about half of wages and capital income.2
This is often described as a “license to spend,” because dependable income can give retirees more confidence that income will continue, even if markets fluctuate or retirement lasts longer than expected.
For financial professionals, this is an important insight. Retirement income planning is not only about optimizing returns, it’s also about helping clients avoid “underspending” in retirement.
A client may understand that a portfolio withdrawal strategy is sustainable on paper and still feel uncomfortable spending from it.
By contrast, income that arrives on a predictable schedule can feel more like a paycheck. That difference can influence whether clients fully enjoy the retirement they worked decades to build.
What risks make decumulation planning more complex?
Decumulation planning is difficult because retirees face several risks at the same time.
Market volatility can affect account values. Sequence-of-returns risk can make early retirement losses more damaging. Longer life expectancies can stretch income needs over 20, 30, or more years.
There is also a practical difference between portfolio value and retirement lifestyle. Account balances may rise and fall, but most retirees still need income to cover essential expenses, discretionary spending, and unexpected costs.
That is why retirement planning is increasingly shifting from a single focus on maximizing account balances to a broader conversation about income certainty.
For many clients, the goal is not simply to have more assets. The goal is to know which assets can support income, when that income can begin, and how long it can last.
What does this mean for financial professionals?
Financial professionals who help clients move from accumulation to decumulation can deliver value that goes beyond investment management. They can help clients understand the role of protected income, identify income gaps, and create a plan that supports both confidence and flexibility.
Annuities, including fixed indexed annuities, may play an important role in that conversation. Products such as the Guaranty Guidepath Income FIA were designed with this transition in mind.
By combining growth potential with protected income features, the planning conversation can move beyond account value and toward a more practical question:
How can clients turn their savings into reliable income they can withdraw throughout retirement with greater confidence?
The right approach depends on the client’s goals, timeline, risk tolerance, income sources, and broader retirement plan.
In Conclusion: Retirement Confidence Depends On More Than Saving Enough
The transition from accumulation to decumulation is one of the most important shifts clients make in retirement. It asks them to move from building wealth to withdrawing income in a way that feels sustainable.
For many retirees, that shift is harder than expected. A well-designed income strategy can help make accumulated assets feel more dependable, accessible, and connected to their retirement goals.
As more Americans enter retirement, financial professionals who can guide this conversation clearly will be positioned to deliver something clients deeply value: greater retirement income certainty.
