A significant gap exists between what retirees expect to pay for healthcare and what they actually spend. Recent research reveals that roughly two-thirds of Americans approaching retirement substantially underestimate their out-of-pocket medical costs, often by thousands of dollars annually. A January 2025 study by Jackson National Life Insurance found that 66% of pre-retired investors expect annual healthcare expenses of around $7,380—but the realistic estimate sits closer to $8,600, a difference of at least $1,220 per year. For a retiree living 20 or 30 years in retirement, this underestimation compounds into a six-figure planning blind spot. The consequences of this miscalculation ripple through retirement security.
When retirees fail to account for true healthcare costs, they may deplete savings faster than anticipated, reduce spending on other necessities, or delay needed medical care. According to the same Jackson study, only 48% of pre-retirees explicitly factor higher healthcare expenses into their retirement planning, and just 16% report feeling knowledgeable about likely healthcare payment amounts. This lack of preparation leaves many Americans vulnerable to unexpected medical expenses at a time when earning potential has ended and savings must last decades. Understanding the true scope of healthcare spending is not merely an accounting exercise—it is fundamental to securing a stable retirement. The data shows that nearly half of retirees harbor misconceptions about Medicare coverage, believing it shields them from far more costs than it actually does. By examining what recent studies reveal about this underestimation, retirees and their advisors can build more realistic budgets and make better financial decisions.

Why Do Pre-Retirees Consistently Underestimate Healthcare Costs?
The underestimation of healthcare costs stems from several structural and behavioral factors. Many americans have limited visibility into actual medical expenses because employer-provided health insurance historically shielded workers from the true cost of care. When transitioning to medicare and supplemental coverage, retirees encounter different deductibles, copayments, and out-of-pocket maximums that bear little resemblance to their working years’ experience. The Jackson National study found that this knowledge gap is severe: only 16% of pre-retirees feel knowledgeable about likely healthcare payment amounts, suggesting that financial planning for this major expense relies on guesswork rather than evidence. Another factor is the assumption that Medicare covers far more than it actually does. A 2024 Schroders survey found that 49% of retirees believed Medicare covers more healthcare than it genuinely provides.
This misconception directly translates into lower estimated costs. For example, a retiree might assume Medicare fully covers prescription drugs, preventive services, and specialist visits—only to discover significant gaps in coverage once enrolled. Long-term care, dental work, vision services, and hearing aids remain largely uncovered by Medicare, costs that can easily exceed $5,000 to $15,000 annually for a retiree requiring multiple services. The tendency to anchor expectations to current experience also plays a role. Younger workers often compare their anticipated retirement medical expenses to their current, typically lower healthcare spending. They reason: “I spend $200 a month on healthcare now, so maybe $300 in retirement”—a calculation that ignores both the nonlinear increase in healthcare utilization with age and the different cost structure of Medicare. This anchoring bias, combined with limited access to realistic cost data, perpetuates the underestimation cycle.
What Are the Actual Healthcare Costs Retirees Should Plan For?
The financial reality of retirement healthcare is substantial and growing. Fidelity’s 2025 estimates indicate that a 65-year-old retiring in 2025 should plan for approximately $172,500 in total healthcare costs throughout retirement—a 4% increase from 2024 figures. This estimate covers Medicare premiums, deductibles, copayments, coinsurance, and out-of-pocket spending for services Medicare doesn’t fully cover. For married couples, the figure balloons to approximately $345,000, reflecting the combined costs for two people over multiple decades of retirement. Breaking down these costs reveals why the aggregate figure surprises many retirees.
The Jackson study identified that pre-retirees expect annual healthcare expenses around $7,380 but the realistic estimate is $8,600—a difference that compounds significantly over time. Additionally, research from the Center for Retirement Research at Boston College found that the median retiree spends $5,444 annually on medical costs, a figure that tends to rise as individuals age into their 80s and 90s when chronic conditions become more prevalent. When factoring in premiums for Medicare Part B, Part D, and Medigap supplemental coverage, many retirees find that healthcare costs consume 15% to 25% of their total retirement budget. A critical limitation in current planning is that most estimates assume relatively stable healthcare costs, when in reality medical inflation typically outpaces general inflation. Additionally, these figures do not account for potential long-term care needs, which can add $60,000 to $100,000 annually if nursing home or assisted living becomes necessary. The Boston College research noted that only 71% of social security benefits remain after medical premiums and costs are subtracted, leaving many retirees dependent on savings to cover other living expenses—a shortfall that forces difficult choices between healthcare and housing, food, or other necessities.
How Does Medicare Coverage Actually Work, and What Does It Miss?
Many retirees discover that Medicare provides broad coverage in some areas but leaves significant gaps in others, a mismatch that drives the underestimation of costs. Medicare Part A covers hospital stays, skilled nursing facility care, hospice, and home health services. Medicare Part B covers doctor visits, outpatient services, and some preventive care. However, both parts require beneficiaries to pay deductibles, coinsurance amounts, and copayments. For 2025, the Part A deductible alone is $1,676 per benefit period, meaning that a single hospitalization could immediately trigger thousands in out-of-pocket costs. The gaps in Medicare coverage are where financial surprises accumulate.
Dental services, vision care, hearing aids, and routine eye exams are not covered by original Medicare, leaving retirees to pay out-of-pocket for these common needs. Prescription drug coverage through Part D requires monthly premiums and involves deductibles and coverage gaps (the “donut hole”), meaning retirees may pay higher percentages of drug costs once spending reaches certain thresholds. Long-term care—whether nursing home, assisted living, or home care—is almost entirely the retiree’s responsibility after Medicare-covered skilled nursing periods end. A retiree requiring in-home care services might face $20 to $30 per hour for aides, adding up to $40,000 to $60,000 annually for full-time support. To address these gaps, many retirees purchase Medigap supplemental insurance, which covers some of the costs Medicare doesn’t, but this too comes with monthly premiums ranging from $150 to $400+ depending on the plan and location. The Schroders research showing that 49% of retirees misunderstand Medicare’s actual coverage underscores how widespread the confusion is. Retirees often discover these gaps only after enrolling, when they encounter a dental bill or realize their hearing aid costs are not reimbursed, forcing them to either absorb unexpected expenses or reduce other spending.
What Should Retirees and Pre-Retirees Do to Prepare for True Healthcare Costs?
Accurate planning begins with replacing assumptions with data. The Jackson study found that only 48% of pre-retirees explicitly account for higher healthcare expenses in their retirement planning, leaving the majority to wing it. The first practical step is to use evidence-based cost estimates rather than guesses—resources like Fidelity’s annual healthcare cost analysis, the Jackson study findings, and Medicare.gov’s own cost calculators provide realistic numbers that can be plugged into retirement projections. A 55-year-old pre-retiree should calculate what Medicare Part B and D premiums will cost in retirement, estimate supplemental insurance premiums based on age and location, and add realistic out-of-pocket amounts for services not covered by Medicare. The second step is to stress-test a retirement plan against higher-than-expected healthcare costs. If a retiree’s plan assumes $8,600 in annual healthcare costs but actual expenses reach $12,000, will savings still last 30 years? This kind of scenario planning is more strong than point estimates.
Many financial advisors recommend setting aside a dedicated healthcare reserve—a buffer that accounts for the possibility that costs exceed initial estimates or that unexpected conditions (like the need for hearing aids or dental implants) arise. Couples should also plan separately, since each spouse may have different healthcare needs and costs. Third, retirees should understand their coverage options thoroughly before enrolling in Medicare. The Jackson study’s finding that only 16% of pre-retirees feel knowledgeable about likely healthcare payment amounts suggests that education is lacking. Reviewing Medicare plan options, understanding which services are covered and which are not, and calculating the total cost of different plan combinations (Original Medicare plus Medigap plus Part D versus Medicare Advantage plans with built-in drug coverage) can reveal significant savings. However, this comparison work is complex, and many retirees benefit from working with a Medicare specialist or financial advisor to make informed choices rather than defaulting to the first plan they encounter.
What Are Common Misconceptions About Healthcare Costs in Retirement?
The most pervasive misconception, as evidenced by the Schroders finding that 49% of retirees believe Medicare covers more than it does, is that Medicare is comprehensive health insurance. Many retirees expect Medicare to function like employer insurance, covering most healthcare needs with minimal out-of-pocket costs. In reality, Medicare is a partial coverage program with significant gaps and cost-sharing requirements. A retiree might reasonably expect that a routine doctor visit costs a small copayment, only to discover that Medicare Part B pays 80% of the cost after a deductible, leaving the retiree responsible for 20%—which on an expensive specialist visit can be thousands of dollars. Another misconception is that healthcare costs remain relatively stable throughout retirement. In fact, healthcare spending typically increases sharply in the late-70s and 80s as chronic conditions like heart disease, diabetes, and arthritis become more common and require ongoing treatment and medication. A retiree who budgeted $8,600 in annual healthcare costs at age 65 may find that figure growing to $15,000 or more by age 80.
Additionally, many retirees fail to anticipate the cost of long-term care until they or a spouse faces cognitive decline or mobility limitations. Nursing homes can cost $60,000 to $120,000 annually, and assisted living facilities range from $40,000 to $80,000 per year depending on location and services. Because Medicare does not cover these costs, many retirees must deplete assets rapidly or turn to Medicaid, which has strict income and asset limits. A warning worth emphasizing: delayed healthcare decisions in retirement often lead to higher costs later. A retiree who postpones addressing hearing loss, vision problems, or dental issues may face more severe and expensive health consequences down the line. For example, untreated hearing loss has been linked to cognitive decline and increased risk of falls and injuries. Likewise, an untreated cavity can escalate into an expensive root canal or extraction. The pressure to minimize near-term healthcare spending can inadvertently increase long-term costs, a tradeoff that many retirees only recognize after the fact.
How Does Healthcare Cost Underestimation Affect Retirement Security and Longevity Risk?
The financial consequences of underestimating healthcare costs directly threaten retirement security. The Boston College research found that only 71% of Social Security benefits remain after medical premiums and costs are subtracted, meaning that a retiree with a $2,000 monthly Social Security benefit loses roughly $580 to healthcare expenses, leaving $1,420 for housing, food, utilities, and other necessities. If actual healthcare costs exceed the budgeted amount, retirees must either reduce spending in other categories—potentially lowering quality of life—or draw down savings at a faster rate, increasing the risk of running out of money. This cost shock disproportionately affects lower and middle-income retirees who lack substantial assets to absorb unexpected expenses.
A retiree with $500,000 in savings can absorb a $5,000 jump in annual healthcare costs. A retiree with $100,000 in savings, by contrast, faces a 5% annual hit to the safety margin. The underestimation problem, therefore, is not merely a planning inconvenience; it is a potential pathway to financial hardship. Research has shown that unexpected healthcare expenses are a leading cause of late-life bankruptcy among retirees, a preventable outcome if costs are accurately anticipated and planned for during the working years.
What Does the Future Hold for Retiree Healthcare Costs?
Healthcare costs are unlikely to stabilize or decline in coming years. Medical inflation has consistently outpaced general inflation, and demographic shifts—an aging population requiring more care—suggest costs will continue to rise. For future retirees entering retirement in 2030, 2040, or beyond, the underestimation problem may worsen if awareness and planning practices do not improve.
The ongoing debate over Medicare’s solvency, potential changes to benefits or cost-sharing rules, and the rising prevalence of chronic diseases in younger cohorts all point toward a future in which retirees bear even more healthcare financial responsibility. On a more positive note, greater data availability and research like the Jackson National study are beginning to illuminate the true costs of retirement healthcare. As more retirees openly discuss their actual healthcare spending and as financial planning tools improve, the information gap that currently drives underestimation should narrow. Retirees and pre-retirees who engage with evidence-based cost estimates and build realistic healthcare budgets today are positioning themselves to avoid the financial surprises that have caught so many of their peers off guard.
