A Texas A&M study found something quietly alarming: financial literacy peaks around age 53 and declines steadily after that — at roughly 2 percent per year after age 60. The part of that finding that actually keeps me up at night when I think about how retirement risk gets discussed: financial confidence stays flat.

People do not feel themselves getting worse at financial decisions. They feel exactly as capable at 72 as they did at 52. That gap — between declining ability and unchanged confidence — is not just a curiosity. It is where financial disasters happen. Overconfident in their own judgment, resistant to oversight, and statistically more vulnerable to exploitation, older adults face a risk to their financial wellbeing that almost no one plans for.

We spend enormous energy planning for market downturns, tax efficiency, and healthcare costs in retirement. Those are real risks, and they deserve attention. But I have followed enough families dealing with the aftermath of undetected cognitive decline — accounts drained by scammers, inappropriate investment decisions made without anyone noticing, legal authority in the wrong hands — to know that this is the retirement risk that flies under the radar until it is too late.

This guide is for people in their 50s and 60s who want to plan ahead. It is also for adult children who are starting to worry about aging parents. The strategies here are not complicated. But they require acting while you still clearly have the capacity to act — and that window is narrower than most people realize.

The Research: A Gap That Creates Disasters

The academic foundation here comes from a landmark 2009 study by Sumit Agarwal and colleagues — often called the “age of peak financial decision-making” paper — published in the Proceedings of the National Academy of Sciences. The researchers analyzed credit card balance transfers, home equity loans, and other financial products across a large dataset, measuring how often people made costly errors.

The findings were striking. Financial decision-making ability followed an inverted U-curve, peaking around age 53 and declining steadily on either side. Older adults made meaningfully more financial mistakes — paying higher interest rates, leaving money on the table, falling for unfavorable terms — than their middle-aged counterparts.

The Texas A&M research built on this with a specific focus on confidence. Across their samples, older adults consistently rated their own financial ability as high even as objective performance measures declined. The researchers described it as a kind of anosognosia applied to financial capacity — an inability to perceive the deficit itself.

This is not a character flaw. It is biology. The prefrontal cortex — responsible for complex reasoning, impulse control, and the ability to evaluate trade-offs — is among the first regions affected by age-related cognitive changes. And because the decline is gradual, neither the individual nor their family typically notices it in real time.

What this means practically:

• Normal aging brings reduced processing speed, slower recall, and diminished ability to evaluate complex information — all of which impair financial decision-making without meeting any clinical threshold for dementia
• Mild Cognitive Impairment (MCI) is estimated to affect roughly 15 to 20 percent of adults over 65, and MCI significantly elevates financial vulnerability
• Dementia — Alzheimer’s and related conditions — affects approximately 10 percent of adults over 65 and nearly one-third of those over 85, according to the National Institute on Aging

The financial implications are not subtle. Retirement assets — built over a lifetime — are concentrated precisely in the years when cognitive protection is weakest.

Thomas’s Take: I want to be clear that this is not a reason to panic or to stop trusting your own judgment. The vast majority of financial decisions in retirement are well within the capacity of healthy older adults. The goal is to build systems and relationships now that catch problems early — the same way we build smoke detectors into houses, not because we expect fires, but because the cost of not having them is catastrophic.

Warning Signs to Watch For

Cognitive decline rarely announces itself with a single dramatic event. It shows up in patterns — small deviations that individually seem explainable, but together form a concerning picture.

In a financial context, the warning signs I would watch for include:

Missed or late bill payments that have no prior history. Not once in a while — a pattern. The ability to track recurring obligations requires working memory and organizational capacity that can slip without the person recognizing it.

Unusual or unexplained purchases. Large transactions to unfamiliar vendors, repeat purchases of the same item, charitable donations that escalate rapidly, or subscriptions that multiply — these can reflect impulsivity, susceptibility to solicitation, or simple confusion about what was already purchased.

Difficulty with tasks that were previously easy. Reading an account statement, understanding a credit card bill, or explaining a recent transaction. If these feel harder than they used to, that is worth noting.

Increased susceptibility to unsolicited contacts. Phone calls from “the IRS,” emails from “your bank,” or door-to-door solicitations that would have been immediately dismissed a few years ago. Scam susceptibility is one of the earliest and most measurable markers of cognitive change.

Withdrawal from financial management. Some people respond to early cognitive difficulty by avoiding financial tasks entirely — letting mail pile up, refusing to discuss account balances, becoming evasive when finances come up. This avoidance can look like disinterest but may reflect awareness that something is harder than it should be.

Confusion about accounts or assets. Not being able to recall where accounts are held, what they contain, or what recent decisions were made.

One important note: these signs can also reflect depression, medication side effects, sleep deprivation, or other reversible conditions. Warning signs warrant a conversation and potentially a medical evaluation — not a conclusion.

Elder Financial Exploitation: The $28.3 Billion Problem

The Consumer Financial Protection Bureau estimates that elder financial exploitation costs older Americans approximately $28.3 billion per year. That figure likely understates the true total — most incidents go unreported, partly out of embarrassment and partly because victims often do not know they have been victimized.

What surprises people most about elder financial exploitation is where it comes from.

The majority of financial exploitation is perpetrated by family members and people known to the victim. Adult children, grandchildren, siblings, neighbors, caregivers, and romantic partners account for a larger share of financial abuse than strangers. That is deeply uncomfortable to acknowledge, but it matters for planning — because people tend to set up financial protections against outsiders while leaving themselves entirely exposed to those they trust.

The forms this takes vary:

• Gradual “borrowing” that never gets repaid
• Being pressured into gifts, loans, or changes to estate documents
• A caregiver gaining account access and making unauthorized withdrawals
• A family member placing themselves as sole beneficiary or POA holder and isolating the elder from other oversight
• Undue influence over investment decisions or asset transfers

Beyond family members, professional exploitation is also common — predatory financial products sold to older adults, annuities with enormous surrender charges, and fraudulent investment schemes that specifically target retirees.

The SEC’s Office of Investor Education and Advocacy has published extensive guidance on protecting senior investors, including a framework for identifying high-pressure or misleading sales tactics that older investors may encounter.

Thomas’s Take: One of the most protective things you can do is maintain multiple people who have visibility into your finances — your advisor, a trusted family member, and your accountant. Exploitation thrives in isolation. When no single person has exclusive access and oversight, the risk drops substantially.

The First Step: Establish a Trusted Contact

Most people do not know this option exists, and it takes about five minutes.

Every major brokerage — Fidelity, Schwab, Vanguard, and others — allows account holders to designate a trusted contact person. This is not a power of attorney. The trusted contact cannot make transactions, access funds, or direct investments. What they can do is receive a call from the brokerage if something unusual is observed — a dramatic change in investment behavior, large unexpected withdrawals, signs of confusion on account calls, or suspected exploitation.

The Financial Industry Regulatory Authority (FINRA) Rule 4512 now requires broker-dealers to make a good-faith effort to collect trusted contact information when opening or updating retail accounts.

Setting this up is straightforward:

1. Contact your brokerage’s customer service or log into your account online
2. Look for “trusted contact” in account settings or profile
3. Provide the name, phone number, and email of your chosen person — typically a trusted family member, close friend, or your attorney
4. This person is notified only if the brokerage has a concern — they are not given ongoing access

This is the lowest-friction, highest-value step I recommend to every client over 55. It creates a safety net without removing any autonomy.

Durable Power of Attorney: Set It Up Now, While You Still Can

Here is the uncomfortable truth that most people avoid: a power of attorney can only be created by someone who currently has legal capacity. Once cognitive impairment reaches a certain threshold, a standard POA is no longer legally executable. At that point, the only option is a court-supervised guardianship proceeding — which is expensive, slow, invasive, and often traumatic for families.

A durable financial power of attorney designates a trusted person to manage financial affairs on your behalf if you become incapacitated. “Durable” means it survives incapacity — unlike a standard POA, which terminates if you become mentally incompetent.

Key considerations:

Immediate versus springing POA. An immediate POA is effective now and allows your agent to act at any time. A springing POA only activates upon a triggering event — typically a physician’s certification of incapacity. Springing POAs sound appealing because they preserve more control, but they can be cumbersome to activate at exactly the moment when speed matters most. Your estate attorney can help you evaluate which structure fits your situation.

Choose your agent carefully. This is often a spouse first, then an adult child or sibling. But family relationships are complicated — consider whether your chosen agent has the time, organizational skills, and financial literacy to manage complex accounts, and whether there are any conflicts of interest.

Keep it updated. POAs can become stale. Some financial institutions have their own preferred forms or require recent execution dates. Review yours every three to five years.

Coordinate with your estate plan. Your POA agent and your executor do not have to be the same person, and often should not be. These roles have different responsibilities and timelines. For more on coordinating these pieces, see my guide on estate planning and tax strategies for retirees.

Thomas’s Take: Families regularly spend tens of thousands of dollars on guardianship proceedings that a $300 meeting with an estate attorney could have prevented entirely. The POA conversation feels morbid, but it is one of the most concrete acts of financial self-protection available. If you don’t have one in place, this week is the right time to call an estate attorney.

Simplify Finances Before You Need To

There is a direct relationship between the complexity of someone’s financial life and their vulnerability to financial missteps as they age. Every additional account, every additional password, every additional decision point is another place where something can go wrong.

Most people accumulate financial complexity over a lifetime. Old 401(k)s from employers they left years ago, multiple IRAs opened at different institutions, taxable accounts at three different brokerages, an old annuity from a policy purchased in the 1990s. Each of these has its own rules, logins, beneficiary designations, and required actions.

Simplification is not about giving anything up — it is about reducing the cognitive load required to manage your own financial life.

Practical steps:

Consolidate accounts. Roll old 401(k)s into a single IRA. Consolidate taxable brokerage accounts at one institution. You do not need accounts at five different places for diversification — diversification is about asset allocation, not institution count.

Automate recurring transactions. Set up automatic payment for every recurring bill — utilities, insurance premiums, credit cards (in full), subscriptions. Remove the need for manual action from every obligation that does not require it. I cover this extensively in my guide on building a retirement budget that works.

Eliminate unnecessary complexity in your portfolio. Twenty-seven individual stock positions and a collection of specialized ETFs acquired over decades are harder to manage, monitor, and transfer than a three- or four-fund portfolio. The simplification has no cost and significant long-term benefit.

Close accounts you are not actively using. Old credit cards, dormant savings accounts, and unused brokerage accounts are not just complexity — they are security vulnerabilities and sources of confusion.

Organize documents physically and digitally. A single binder — or a shared folder with a trusted family member — with account statements, insurance policies, beneficiary designations, and advisor contact information is enormously valuable. More on this in the next section.

Pro Tip: The best time to simplify is well before you feel any urgency to do so. Consolidating accounts and automating bills at 58 or 62 is straightforward. Trying to do it at 78 when a family member is attempting to take over management is much harder, and some custodians require extensive documentation for account transfers involving older clients.

The Financial Fire Drill

Think of this as the financial equivalent of knowing where the fire extinguisher is. When everything is calm and nothing is wrong, you create a complete picture that a trusted person can use if they ever need to step in.

The financial fire drill involves documenting and sharing the following with at least one trusted person:

Account inventory. Every account: bank accounts, investment accounts, retirement accounts, 529 plans, annuities. Institution name, account number (at least the last four digits), and approximate balance.

Insurance policies. Life insurance, long-term care insurance, Medicare supplement plans, homeowners, auto. Policy numbers and insurance company contact information. For a full treatment of long-term care planning, see my guide on long-term care insurance.

Advisor and professional contacts. Your financial advisor, estate attorney, CPA or tax preparer, insurance agent. Names, firms, and direct phone numbers.

Login and access information. This is the hardest part for most people. Account passwords and two-factor authentication methods. A password manager (1Password, Bitwarden) with a shared emergency access feature is the most secure way to handle this.

Estate documents. Where to find your will, trust documents, POA, and healthcare directive. The original documents and the name of the attorney who drafted them.

Social Security and Medicare information. Social Security number, Medicare ID number, and how to access the SSA.gov account.

This information does not need to be stored insecurely. A fireproof box at home, a safe deposit box, or a shared encrypted document service with a trusted family member all work. The point is that a trusted person could step in and manage your financial life within 48 hours if they needed to — without spending weeks hunting for account numbers and calling institutions.

Review and update this documentation annually, or whenever there is a significant life change.

A Continuous-Oversight Layer in Your Plan

Not all financial professionals are created equal, and in the context of cognitive protection, the distinction matters.

A fiduciary is legally required to act in the client’s best interest — not to recommend a merely suitable product, not to disclose a conflict and then proceed anyway, but to genuinely act in their interest. That standard generally applies to registered investment advisors (RIAs) but does not apply uniformly to broker-dealers operating under a suitability standard.

The relevance to cognitive protection is straightforward: an ongoing relationship with a fiduciary professional provides continuous oversight in a way that annual tax preparation or sporadic check-ins with a transactional broker do not.

A good fiduciary professional will:

• Notice when investment behavior changes dramatically without a clear rationale
• Flag unusual or out-of-character requests, especially large transfers or withdrawals
• Build a baseline understanding of what “normal” looks like for that household specifically
• Be positioned to contact a trusted contact or family member if there is a serious concern
• Help coordinate with the household’s attorney and accountant when planning documents need updating

This isn’t about giving anyone control of your finances. It’s about maintaining a professional relationship that adds an independent layer of oversight — one with no inheritance stake, no family dynamics, and a legal obligation to act in the client’s interest.

This is exactly the kind of safeguard that depends on relationship continuity — knowing what “normal” looks like for a specific household over years, not weeks. Whoever fills that role for you, the value comes from the long view, not the single conversation.

For an overview of how behavioral patterns affect financial decisions throughout retirement, my post on behavioral finance and retirement mistakes is a useful companion piece.

Investment Simplification as a Cognitive Safety Strategy

There is a strong case for gradually moving toward simpler, more automated investment strategies as you move through retirement — not because complex strategies stop working, but because they require more active management, more monitoring, and more decision points.

This is a principle I think about in terms of the cognitive load of your portfolio — how much active attention your investment strategy requires to function properly.

A portfolio built around a handful of low-cost index funds, with automatic rebalancing, is essentially self-tending. It requires very little active decision-making. A portfolio of individual stocks, actively traded ETFs, alternative investments, and concentrated positions requires ongoing attention, judgment, and the capacity to evaluate complex information.

That does not mean you need to divest everything the day you turn 65. But directionally, over time, moving toward strategies that function well with less active oversight is a form of financial resilience planning.

Practical moves in this direction:

• Consolidate individual stock positions into diversified funds, particularly if the positions represent legacy holdings rather than intentional strategy
• Reduce the number of investment vehicles that require annual decisions — actively managed funds that trigger taxable events, structured products with renewal elections, etc.
• Move toward target-date or all-in-one funds for accounts where simplicity is most important
• Ensure that your withdrawal strategy — how you get living expenses out of your portfolio — is clear, documented, and can be explained simply to a family member who may need to manage it

The psychology of spending in retirement plays directly into this: how you emotionally relate to your portfolio matters as much as its construction, and a simpler structure is typically easier to maintain confidence in over time.

Pro Tip: Automatic rebalancing, automatic RMD distributions, and automatic charitable giving setups are not just conveniences — they are cognitive protection. Every recurring transaction that happens automatically is one fewer decision that needs to be made correctly under potentially diminished capacity.

Having the Conversation with Aging Parents

If you are reading this as an adult child with concerns about a parent — or as someone who anticipates your children might one day need to have this conversation with you — this section is for you.

The cognitive decline conversation is one of the hardest in family life. It touches on mortality, autonomy, control, and trust simultaneously. It often gets delayed until there is a crisis, which is precisely the worst time to have it.

A few things that make this conversation more productive:

Approach it from care, not concern about inheritance. “I want to make sure you’re protected” lands very differently than anything that can be interpreted as interest in what happens to the estate. Be explicit that your motivation is protection.

Use third-party examples to open the door. Bringing up a news story about elder financial exploitation, or mentioning that your own advisor recommended this kind of planning, creates a less personal entry point than a direct observation about your parent’s behavior.

Focus on planning, not capacity. “I want to do this kind of planning myself and I’d love to do it together” positions the conversation as mutual rather than one-sided. Many parents are more receptive to doing something with their adult child than to being told they need help.

Ask to be introduced to their advisor and attorney. Not to take over — just to know who the professionals are, have a relationship, and be able to reach someone if there is ever a concern. A good advisor should welcome this. If an advisor is actively resistant to a family member being involved, that is worth noting.

Get the practical information. Account locations, insurance policies, estate documents, contact information for professionals. Even if your parent is completely sharp and capable today, this information matters in a medical emergency that does not involve cognitive decline at all.

If you have specific concerns about financial decisions already being made, involving a geriatric care manager, an elder law attorney, or your parent’s physician may be appropriate. Adult Protective Services is also a resource when exploitation is suspected.

The goal is not to take over — it is to build the infrastructure of support that makes it possible to help if the time ever comes.

Having an early, calm conversation about financial planning is one of the most protective things families can do.

Key Takeaways

1. The confidence gap is the real danger. Financial ability declines steadily after age 60, but confidence does not. That disconnect creates vulnerability — not negligence. Proactive planning is the antidote.

2. Act while you have capacity. Durable financial power of attorney, trusted contact designations, and simplified account structures can only be put in place cleanly while you are legally and cognitively capable of doing so. The right time is now, not when there is urgency.

3. Most exploitation comes from people you know. Elder financial abuse is predominantly perpetrated by family members and trusted individuals, not strangers. Protection requires oversight across the board — including who has exclusive access to your accounts.

4. Simplicity is a form of security. Consolidated accounts, automated payments, and simpler investment strategies reduce the number of decisions that need to be made correctly and make it easier for a trusted person to step in if needed.

5. A fiduciary advisor relationship is a long-term safeguard. Ongoing professional oversight adds an independent layer of protection that family relationships alone cannot provide — someone with legal obligation, baseline knowledge, and no personal stake in outcomes.

Frequently Asked Questions

At what age should I start planning for cognitive decline affecting my finances?

The research suggests financial decision-making begins declining in the early 60s, with more meaningful changes after 70. But the planning — power of attorney, trusted contacts, account simplification, the financial fire drill — needs to happen while you clearly have capacity, which means your 50s or early 60s is the right time to start. The legal infrastructure in particular (POA, estate documents) cannot be put in place after capacity is lost. There is no age that is too early to have these structures in place.

What is the difference between a trusted contact and a power of attorney?

A trusted contact is a limited designation at a financial institution that allows the institution to contact a named person if they have concerns about account activity or your wellbeing. The trusted contact cannot access your accounts, make transactions, or give instructions. A durable financial power of attorney is a legal document that grants another person the authority to manage your finances on your behalf — either immediately or upon incapacity, depending on how it is structured. Both are useful; they serve very different purposes.

How do I protect a parent who refuses to discuss their finances?

This is one of the most common and most difficult situations families face. A few approaches: involve a neutral third party (their doctor, financial advisor, or elder law attorney) who may be able to raise the topic more effectively; focus conversations on practical emergencies rather than cognitive capacity (“what would happen if you were in the hospital for a week?”); and contact Adult Protective Services or an elder law attorney if you have concrete evidence of exploitation or immediate financial harm. Ultimately, a competent adult has the right to manage their own affairs, even poorly — which is why establishing these structures proactively, before there is a conflict, matters so much.

Can a fiduciary advisor really help catch early cognitive decline?

An advisor who has a long-standing relationship with a client — and who has legal and ethical obligations to that client — is often positioned to notice behavioral changes earlier than family members who see the person less frequently or in different contexts. This includes unusual requests, dramatic changes in risk tolerance, confusion about recent decisions, or susceptibility to unsolicited investment pitches. Advisors can contact a trusted contact if they have concerns, and a good fiduciary advisor will have established protocols for exactly these situations.
