How to Plan for Healthcare Costs in Retirement

Healthcare is the expense that breaks more retirement plans than any other. Surveys consistently show that pre-retirees expect to spend a fraction of what retirees actually pay, and that gap—between the comfortable estimate in your head and the real bills that arrive in your sixties, seventies, and eighties—is exactly what turns a retirement that looked fine on paper into one that runs out of money. The good news is that healthcare costs in retirement are not a mystery. They are large, but they are predictable, and once you understand the real numbers, you can plan for them the same way you plan for any other major expense.

This guide explains how to plan for healthcare costs in retirement. You'll learn how to estimate the real number you're likely to pay, how Medicare works and where its coverage gaps leave you exposed, how to budget for premiums and out-of-pocket costs, why long-term care is the wildcard that sinks the most plans, and how to build a dedicated healthcare sinking fund so medical bills never force you back to work or into debt. The plan works whether you're a decade from retirement or already in your first year.

How much does healthcare cost in retirement?

The number surprises almost everyone. A healthy 65-year-old couple retiring today can expect to pay hundreds of thousands of dollars in healthcare costs over the course of their retirement—commonly estimated at roughly $300,000 to $350,000 in total out-of-pocket medical expenses, and that figure does not include long-term care. For a single person, the estimate is meaningfully lower but still in the six figures. These are not catastrophic, worst-case numbers; they are the ordinary, expected costs of premiums, deductibles, copays, prescriptions, dental, vision, hearing, and the medical care that accumulates simply from growing older.

What makes the number feel overwhelming is that it doesn't arrive as one bill. It arrives in dozens of smaller charges spread across decades—a monthly premium here, a specialist copay there, a dental implant in your seventies, a new prescription in your eighties. Because the costs are spread out, most retirees never add them up, which is why they underestimate them. The first step in planning for healthcare costs in retirement is accepting the real total and then breaking it into annual and monthly amounts you can actually budget for. Once $300,000 over 25 years becomes roughly $12,000 a year, it becomes a line item in your retirement budget instead of a vague fear.

Understanding Medicare: what it covers and what it doesn't

Medicare is the foundation of retirement healthcare in the United States, but it is not free and it does not cover everything. Medicare Part A covers hospital stays and is premium-free for most people, but it carries deductibles and coinsurance. Medicare Part B covers doctor visits and outpatient services and charges a monthly premium that's deducted from your Social Security check, with premiums that rise for higher earners through income-related monthly adjustment amounts, or IRMAA surcharges. Medicare Part D covers prescription drugs, also for a separate monthly premium. None of these premiums are trivial, and together they can consume a meaningful slice of a retiree's monthly income.

The bigger issue is what Medicare does not cover. Original Medicare does not cover routine dental, vision, or hearing care, which means dentures, cataract surgery, and hearing aids—common expenses in retirement—are paid out of pocket. It also does not cover long-term custodial care, which is the single largest uncovered expense most retirees face. There is also no out-of-pocket cap on Original Medicare, meaning a serious illness can generate unlimited cost-sharing. Understanding these gaps is the core of retirement healthcare planning, because the gaps are where the money actually goes.

Filling the Medicare gaps: Medigap vs. Medicare Advantage

To address Original Medicare's cost-sharing and lack of an out-of-pocket cap, retirees choose between two paths. The first is a Medigap policy, also called a Medicare Supplement, which pays the deductibles and coinsurance that Original Medicare leaves behind and adds an annual out-of-pocket limit. Medigap plans offer broad provider access and predictable costs, but they charge a separate monthly premium and do not include prescription drug coverage, so you still need a standalone Part D plan. The second path is Medicare Advantage, or Part C, which replaces Original Medicare with a private plan that bundles hospital, medical, and usually drug coverage, often with dental, vision, and hearing benefits included.

Medicare Advantage plans typically have lower or zero premiums and include an annual out-of-pocket maximum, which protects against catastrophic costs. The trade-off is that they use provider networks, require referrals for specialists in some plans, and can change their benefits and costs each year. Neither option is universally better; the right choice depends on your health, your providers, your prescription drugs, and your tolerance for network restrictions. The key is to make the decision deliberately during your initial enrollment and review it each year during open enrollment, because the choice directly determines your monthly premiums and your exposure to out-of-pocket costs.

Budgeting for premiums and out-of-pocket costs

Once you understand your Medicare coverage, you can build a realistic healthcare budget. Start with the fixed monthly costs: Part B premiums, Part D premiums, and either your Medigap premium or your Medicare Advantage premium if you chose one. These are predictable recurring expenses that come out of your income every month, just like a utility bill. For a typical retiree, these premiums alone can total $200 to $400 per person per month, and they tend to rise each year.

Then add the variable out-of-pocket costs: deductibles, copays, coinsurance, prescriptions, and the dental, vision, and hearing expenses Medicare doesn't cover. A practical approach is to estimate these annually based on your current health and expected usage, then divide by twelve to build a monthly healthcare sinking fund. If you expect $4,000 a year in out-of-pocket costs, set aside roughly $335 a month. By pre-funding the account during healthy years, you build a cushion that absorbs the larger bills that arrive during sick years without forcing you to sell investments or take on debt. Treating healthcare as a monthly budget line, not a surprise expense, is what keeps retirement finances stable.

The wildcard: long-term care costs

Long-term care is the expense that derails the most retirement plans, and it's the one most people are least prepared for. Medicare does not cover ongoing custodial care—the help with bathing, dressing, and eating that becomes necessary as people age—so the cost falls entirely on the retiree. A year in a private room in a nursing home can exceed $100,000, and home health aides and assisted living facilities carry their own substantial costs. Because roughly half of people turning 65 today will need some form of long-term care, ignoring this expense is not a plan; it's a gamble.

Planning for long-term care means choosing a strategy before you need it. Traditional long-term care insurance pays for care but can be expensive and may never be used. Hybrid policies that combine life insurance or an annuity with a long-term care benefit offer a guaranteed payout but require a larger upfront premium. Self-insuring—earmarking a dedicated portion of your savings as a long-term care fund—works for those with substantial assets. Medicaid covers long-term care for those who meet strict asset and income limits, but it requires spending down most of your savings first. There is no single right answer, but there is a wrong one: doing nothing. Deciding on a long-term care strategy in your late fifties or early sixties, while you still have options, is one of the most important moves in retirement healthcare planning.

Using a Health Savings Account (HSA) to pre-fund retirement healthcare

If you are still working and enrolled in a high-deductible health plan, a Health Savings Account is the most powerful retirement healthcare tool available. Contributions are tax-deductible, the money grows tax-free, and withdrawals for qualified medical expenses are tax-free—a rare triple tax advantage that no other account offers. Unlike a flexible spending account, HSA funds roll over year to year and can be invested, so the balance can compound for decades. For retirement planning, the strategy is to contribute the maximum, invest the balance rather than spending it, and pay current medical expenses out of pocket so the HSA can grow untouched.

By your early sixties, a well-funded HSA can hold tens of thousands of dollars earmarked specifically for retirement healthcare costs, and those withdrawals will be tax-free as long as they're used for qualified medical expenses. After age 65, the HSA can even be used for Medicare premiums and non-medical expenses, though non-medical withdrawals are taxed as income without penalty. If you're still years from retirement and eligible for an HSA, maxing it out is one of the highest-leverage moves you can make for future healthcare costs. If you're already retired, the lesson is to understand the role an HSA could have played and to build an equivalent dedicated healthcare fund from your other savings.

How to estimate your personal healthcare cost number

The national averages are a starting point, but your personal number depends on your health, your family history, your longevity, and your coverage choices. To estimate it, start with the standard benchmark for a couple or individual retiring at 65, then adjust based on your situation. If you have a chronic condition, a family history of serious illness, or expect to live well into your nineties, adjust upward. If you're in excellent health, have good longevity genes, and chose robust coverage with low out-of-pocket exposure, you may adjust slightly downward—but be careful not to underestimate, because healthcare inflation consistently outpaces general inflation.

Once you have your total estimate, break it into an annual figure and then a monthly figure. Compare that monthly number to your expected retirement income from Social Security, pensions, and portfolio withdrawals. If healthcare consumes a large share of your income, you may need to save more before retirement, work a year or two longer, or adjust your coverage strategy. The goal of the exercise is not precision—it's to replace a vague fear with a concrete number you can plan around. A retirement plan that ignores healthcare costs is a plan built on a hidden deficit; a plan that includes them is a plan that can actually survive the decades ahead.

Building a healthcare sinking fund

A sinking fund is money set aside over time for a known future expense, and it's the perfect structure for retirement healthcare costs. Rather than paying medical bills out of monthly cash flow and scrambling when a large bill arrives, you build a dedicated healthcare fund that grows during healthy years and draws down during expensive ones. In retirement, this fund sits alongside your living-expenses cash buffer and your investment portfolio, earmarked specifically for premiums, out-of-pocket costs, dental and vision care, and the eventual possibility of long-term care.

A practical structure is to keep one to two years of expected healthcare costs in a safe, liquid account—like a high-yield savings account or short-term bonds—so you can pay bills without selling investments in a down market, and to keep a longer-term healthcare reserve invested conservatively to outpace inflation. Review the fund each year, top it up from portfolio withdrawals during good years, and let it absorb the shocks during expensive ones. The psychological benefit is enormous: when a medical bill arrives, it's already paid for, because the money was set aside years earlier. That peace of mind is the real reward of healthcare planning.

Common healthcare planning mistakes to avoid

Several mistakes recur among retirees who underestimate healthcare costs. The first is assuming Medicare covers everything, which leaves people shocked by premiums, dental bills, and the lack of long-term care coverage. The second is ignoring IRMAA—higher-income retirees can pay hundreds more per month in Part B and Part D premiums, and a large one-time income event, like a Roth conversion or selling a business, can trigger surcharges for the year. The third is buying long-term care insurance too late, when premiums are unaffordable or health issues make you uninsurable.

A fourth mistake is failing to coordinate healthcare planning with tax planning. Because Medicare premiums are based on your income from two years prior, large withdrawals or conversions can raise your premiums years later. A fifth mistake is not reviewing coverage annually—Medicare Advantage plans and Part D drug formularies change every year, and a plan that was best-in-class can become expensive or drop your medications. Avoid these by understanding Medicare's gaps, planning IRMAA-triggering income carefully, addressing long-term care in your late fifties, and reviewing your coverage every fall during open enrollment.
