Retirement risk is not abstract, it shows up in very concrete money mistakes that can quietly push an older adult from stability into poverty. I focus here on six specific errors that research has tied to higher poverty risk in retirement and explain how each one can be avoided before it is too late.
1) No Dedicated Retirement Savings Plan
No dedicated retirement savings plan is the first and most fundamental mistake that can push someone into poverty. According to the Transamerica Center for Retirement Studies 2023 report, 57% of workers have no dedicated retirement savings plan at all, which means they are on track to rely almost entirely on Social Security. The Social Security Administration reports that the average monthly retirement benefit in 2024 is $1,907, an amount that may barely cover rent and basic groceries in many parts of the United States, let alone healthcare, transportation, and unexpected bills. When I compare that $1,907 to typical budgets for housing, utilities, food, and Medicare premiums, it is clear that a worker who reaches age 67 with no savings is at high risk of falling below the poverty line if anything goes wrong. Research on Retirement planning mistakes stresses that not having a written plan, including target savings rates and investment choices, is one of the core errors that undermines long term security.
Several studies on Six common saving mistakes point out that “Mistake #1: Not having a plan” and “Mistake #2: Delaying savings” often go together, and both are strongly associated with inadequate balances by the time someone reaches their early sixties. I see the same pattern in surveys that show workers who never enroll in a 401(k) or individual retirement account tend to underestimate how much income they will need and overestimate how long they can keep working. The Harvard Gazette’s discussion of why it is so hard to save for retirement, framed around the question “Why is it so hard to save for retirement these days?”, notes that the complexity of the financial system means You often need explicit guidance just to choose a plan. Without that structure, many people default to doing nothing, which effectively locks them into a future where $1,907 per month is the main income stream. The stakes are highest for workers in low wage jobs who lack employer plans, because every year without contributions is a year when compound growth is lost, and that missing growth is what separates a modest but stable retirement from one where a single rent increase can trigger a downward spiral into poverty.
2) Early Withdrawals from Retirement Accounts
Early withdrawals from retirement accounts are a second major mistake that can quietly erode long term security and increase poverty risk. A 2022 analysis from Fidelity Investments shows that taking money out of a 401(k) before age 59½ typically triggers a 10% early withdrawal penalty on top of ordinary income taxes. When someone pulls out funds in financial distress, they not only lose the withdrawn principal, they also forfeit decades of potential investment growth, and Fidelity’s modeling indicates that repeated early withdrawals can reduce lifetime retirement savings by up to 25%. That kind of reduction is not just a paper loss, it translates into hundreds of dollars less in monthly income in someone’s seventies and eighties. Guidance on Retirement planning mistakes emphasizes that tapping long term accounts to cover short term gaps is one of the most damaging choices a worker can make, because it converts a temporary cash crunch into a permanent cut in future living standards.
When I look at how this plays out in real budgets, the danger becomes obvious. Suppose a worker in their forties withdraws $20,000 from a 401(k) to pay off credit cards, pays a 10% penalty plus 22% federal income tax, and ends up with only about $13,600 in hand. If that $20,000 had stayed invested for twenty years with a moderate 6% annual return, it could have grown to more than $64,000, which might have supported an extra $250 per month in retirement income. Research on Act now to avoid mistakes in later life shows that older adults often regret “Not saving enough” and “Avoiding the stock market,” but they also regret raiding accounts that were meant for old age. The CNBC discussion of money errors in midlife warns that Making minimum payments on high interest debt while simultaneously pulling from retirement is a double hit, because it preserves expensive borrowing while destroying tax advantaged savings. For someone already on track to rely heavily on Social Security, a 25% cut in private savings can be the difference between covering basic bills and needing food assistance or housing subsidies in old age.
3) Underestimating Healthcare Costs
Underestimating healthcare costs is a third mistake that can push even diligent savers toward poverty in retirement. The Employee Benefit Research Institute 2023 Retirement Confidence Survey reports that 41% of retirees underestimate what they will spend on healthcare, and it estimates that a typical couple retiring at age 65 will need about $315,000 in out of pocket medical expenses over the rest of their lives. That figure includes premiums, deductibles, copays, and uncovered services, and it comes on top of ordinary living costs like housing and food. When I compare that $315,000 estimate to the average Social Security benefit of $1,907 per month, it is clear that relying on public benefits alone leaves almost no margin for error. The retirement budget mistake analysis warns that “Rolling your eyes at another healthcare cost warning” is itself a budget error, because medical inflation and the rising cost of long term care routinely catch retirees off guard.
Planning experts who focus on Retirement planning mistakes consistently highlight healthcare as a category that people either ignore or grossly underestimate when they build their spreadsheets. I see the same pattern in pre retirement checklists that urge workers to model Medicare premiums, Medigap policies, and potential long term care needs explicitly, rather than assuming that government programs will cover everything. When 41% of retirees misjudge these expenses, the result is that savings that looked adequate on paper can be drained rapidly by a few hospitalizations or a chronic condition. For lower income retirees, high out of pocket costs can force painful tradeoffs between medications and rent, or between specialist visits and groceries, which is exactly how medical issues push people below the poverty line. The guidance on Act now to avoid later regret includes a warning that “Rolling” healthcare into a generic budget line is not enough, and that failing to adjust spending patterns when medical bills rise can quickly destabilize an otherwise balanced retirement plan.
4) Lack of Investment Diversification
Lack of investment diversification is a fourth mistake that quietly undermines retirement security by reducing returns and increasing risk. A 2021 study from Vanguard finds that retirees who hold undiversified portfolios, for example concentrating heavily in a single stock or sector, tend to underperform more balanced portfolios by 2% to 3% per year. The same study reports that 28% of retirees have undiversified assets, which means more than a quarter of older investors are accepting lower returns and higher volatility at exactly the stage of life when they can least afford large losses. Over a twenty year retirement, a 2% to 3% annual gap compounds into a dramatically smaller nest egg, and that smaller pool of assets translates directly into less income to supplement Social Security. The guidance on Six common mistakes lists “Not” diversifying and “Avoiding the” stock market as errors that can leave a portfolio both too risky and too low growth, a combination that increases the odds of running out of money.
When I translate those percentages into dollar terms, the stakes become clear. If two retirees each start with $300,000, and one earns 6% annually in a diversified mix while the other earns 3% to 4% in an undiversified, poorly allocated portfolio, the gap after twenty years can exceed $200,000. That difference can mean the ability to cover rising property taxes, home repairs, and medical bills versus being forced to sell a home or rely on adult children. The analysis of Avoiding the stock market entirely shows that older adults who keep everything in cash or a single conservative product often fail to keep up with inflation, which erodes purchasing power year after year. At the same time, concentrating in a single employer stock or a narrow set of holdings exposes retirees to the risk of a company specific downturn wiping out a large share of their wealth. For someone already depending on $1,907 per month from Social Security, a poorly diversified portfolio that underperforms by 2% to 3% annually can be the difference between a modest but stable lifestyle and a gradual slide into poverty as prices rise faster than investment income.
5) Carrying High-Interest Debt into Retirement
Carrying high interest debt into retirement is a fifth mistake that directly drains limited income and raises poverty risk. A 2024 report from AARP finds that 35% of Americans aged 50 and older carry high interest debt into retirement, with credit card rates averaging 21.5% APR. At that rate, even a relatively modest balance can cost more than $5,000 per year in interest alone, which is a huge burden when someone is living on a fixed income. If a retiree’s primary guaranteed income is the average Social Security benefit of $1,907 per month, losing over $400 per month to interest payments can consume a quarter of that check before housing, food, or healthcare are even addressed. The CNBC guidance on avoiding money errors in midlife warns that Not having an emergency fund and “Making minimum payments on high interest debt” sets up a cycle where balances never shrink, which is especially dangerous as someone approaches retirement.
When I look at pre retirement checklists, the message is consistent. The analysis of Common Pre retirement planning mistakes that May Cost You Dearly highlights that entering retirement with significant credit card or personal loan balances is one of the most avoidable errors, yet it remains widespread. That same guidance notes that “Moving” to a lower cost area can help, but only if Americans also tackle the underlying debt rather than simply shifting it to new cards. The AARP discussion of Claiming Social Security early warns that some older adults start benefits as soon as possible just to service high interest balances, which permanently reduces their monthly checks and locks in a lower income for life. For a retiree already on the edge, a 21.5% APR credit card can function like a reverse savings account, siphoning away the very dollars that could have been used to build a small emergency fund or pay for preventive healthcare. Over time, that constant drain increases the likelihood that a job loss, medical bill, or rent hike will tip the household into poverty.
6) Failing to Plan for Working Longer
Failing to plan for working longer is the sixth mistake that can leave near retirees exposed to poverty as they age. A 2023 study from the National Institute on Retirement Security reports that 52% of near retirees expect to work longer because of inadequate savings, yet many have not built realistic plans for what that extended work life will look like. At the same time, the study notes that inflation adjusted Social Security benefits have declined 20% in real terms since 2000, which means that each dollar of benefit buys significantly less than it did a generation ago. When I combine those two facts, I see a troubling picture. More than half of people approaching retirement are counting on extra years of earnings to make up for shortfalls, but the public benefit they will eventually receive has lost purchasing power, and there is no guarantee that health or labor market conditions will allow them to keep working as long as they hope. The Harvard Gazette’s discussion of retirement anxiety, framed around the question “Why is it so hard to save for retirement these days?”, notes that the complexity of the system means You often delay decisions until late in life, which can leave little room to adjust if work ends unexpectedly.
Guidance on Retirement Planning Mistakes that May Cost You Dearly emphasizes that “Not doing the math” on realistic retirement ages and income sources is a central error. Many Americans assume they can simply delay retirement to age 70 or beyond, but surveys show that health issues, caregiving responsibilities, or layoffs often force people out of the workforce earlier than planned. The analysis of Retirement planning mistakes also warns that moving without researching cost of living, or “Moving” to a region with limited job opportunities, can make it harder to find the late career work that a plan depends on. When 52% of near retirees are counting on working longer in an environment where Social Security has lost 20% of its real value since 2000, the margin for error is thin. If those extra working years do not materialize, or if wages are lower than expected, the result can be a sudden drop from a modest but manageable lifestyle into one where every bill is a struggle and poverty becomes a real possibility.
