How Much Does Healthcare Cost in Retirement?
For most people, Medicare becomes their primary source of medical coverage in retirement. Once you turn 65, it’s the default health insurance option for the vast majority of Americans, and planning for its costs is a meaningful part of planning for retirement overall.
Healthcare is typically one of the larger expenses in retirement, and Medicare is the foundation of how most retirees manage it. Understanding what Medicare costs, how the different parts work together, and what your realistic out-of-pocket exposure looks like is worth doing before you get there, not after.
There are several different paths you can take with Medicare, and the costs vary widely depending on which direction you go. This article focuses on Original Medicare paired with a comprehensive Medicare supplement policy, because the goal here is to answer a more specific question: what would someone pay for comprehensive, predictable Medicare coverage in retirement, and what is the realistic maximum out-of-pocket in a given year?
Here is a plain-English breakdown of what each part costs in 2026.
Part A: Hospital Coverage
Part A covers inpatient hospital care, skilled nursing facility stays, hospice, and some home health services.
For most people, Part A has no monthly premium. Roughly 99% of Medicare beneficiaries have at least 40 quarters of Medicare-covered employment, which means they earned their Part A coverage through work history and pay nothing monthly for it.
That said, using Part A is not free. The inpatient hospital deductible is $1,736 in 2026, and it applies per benefit period, not per calendar year. A benefit period begins the day you are admitted to the hospital and ends once you have been out of the hospital or skilled nursing facility for 60 consecutive days. If you are readmitted after that 60-day window, a new benefit period begins and the deductible resets. If a hospital stay extends past 60 days within a single benefit period, daily coinsurance costs begin to add up as well. This is one of the main reasons people add a Medicare supplement policy.
Part B: Medical Coverage
Part B covers doctor visits, outpatient care, lab work, preventive services, and durable medical equipment.
The standard Part B premium is $202.90 per month in 2026, and for most people it is automatically deducted from their Social Security check. The annual Part B deductible is $283 in 2026. After the deductible, Medicare covers 80% of approved costs. You are responsible for the remaining 20%, and under Original Medicare alone there is no annual cap on that exposure.
Higher-income beneficiaries pay more. Through a surcharge called IRMAA, the monthly Part B premium can range from $284.10 to $689.90 depending on your modified adjusted gross income. Medicare uses your tax return from two years prior, so a high-income year in retirement can affect your premiums down the road. For retirees doing Roth conversions or taking large distributions, this is worth paying attention to.
Medigap (Medicare Supplement): Filling the Gaps
Original Medicare leaves meaningful cost exposure. The Part B deductible, the 20% coinsurance with no cap, and the Part A hospital deductible are all your responsibility unless you have additional coverage. A Medigap policy, sometimes called a Medicare supplement, is private insurance designed to cover some or all of those gaps.
Premiums vary based on the plan type, your age, your location, and the insurer. They can range from around $50 per month for leaner coverage to several hundred dollars per month for more comprehensive plans.
Plan G is the premium option among Medigap plans, and it is priced accordingly. It covers nearly everything except the Part B deductible, which means after you pay that $283 Part B deductible once per year, your cost-sharing is largely taken care of. Think of Plan G as the Rolls Royce of Medicare supplement policies. You will pay more in monthly premiums than you would with a leaner plan or no supplement at all, but in exchange you get a structure where almost nothing slips through unexpectedly. One hospitalization without a good supplement can cost more than a full year of Plan G premiums. For people who want to budget for healthcare in retirement without worrying about open-ended exposure, Plan G earns its reputation.
Because Medigap plan structures are standardized by the federal government, a Plan G from one insurer offers the same core benefits as a Plan G from another. The premiums, however, are not standardized and vary enough by zip code and carrier that comparing options in your area is worthwhile.
Part D: Prescription Drug Coverage
Part D covers prescription medications and is sold through private insurance companies. You can enroll in a standalone Part D plan alongside Original Medicare, or get drug coverage bundled into a Medicare Advantage plan.
Standalone Part D premiums vary considerably. In 2026, plans in many markets start as low as a few dollars per month, with the most expensive plans running around $150 per month. The right plan depends heavily on which medications you take, so it is worth comparing plans during the annual enrollment period each fall rather than defaulting to the lowest premium. Part D plans can have a deductible of up to $615 in 2026, though some plans have a lower deductible or no deductible at all.
One meaningful recent change is the cap on out-of-pocket drug spending. Thanks to the Inflation Reduction Act, the so-called donut hole was eliminated in 2025 and a hard cap on Part D out-of-pocket costs was introduced. In 2026, once you have spent $2,100 out of pocket on covered medications, you enter the catastrophic coverage phase and your plan pays 100% of your covered drug costs for the rest of the year. Before this change, there was no ceiling on what beneficiaries could spend on prescriptions, which was a serious financial risk for people on expensive specialty medications. That $2,100 cap includes your deductible, copays, and coinsurance, but does not include your monthly premium.
A Real-World Example: 65-Year-Old Male in Lakewood, Colorado
Numbers are easier to think about when they are concrete. To make this as practical as possible, we used the zip code for IronFjord Wealth Management's office in Lakewood, Colorado (80228) to pull actual plans available in that market. Here is what a 65-year-old male enrolling in Original Medicare in that zip code might pay in 2026.
For this example we selected Plan G, which is currently the most comprehensive Medigap option available to new Medicare enrollees. The goal was to illustrate what a thorough Original Medicare experience looks like in terms of both premiums and out-of-pocket exposure. It is worth noting that other Medigap plans are available, such as Plan N, which carry lower monthly premiums in exchange for potentially higher out-of-pocket costs when you use care.
We selected a policy with issue-age pricing, which means your premium is based on the age at which you first enroll and does not increase simply because you get older. Issue-age plans tend to start at a slightly higher premium than attained-age plans for a 65-year-old, but because your age does not drive future increases, they can be more stable and predictable over time. Attained-age plans may look cheaper at 65 but are designed to increase as you age, which can make them more expensive in later retirement when healthcare needs tend to be higher.
The goal with this example was to show what comprehensive coverage, with the smallest possible age-driven premium increases, could look like in practice.
The monthly premiums:
Part A: $0 (assuming at least 10 years of work history)
Part B: $202.90
Plan G Medigap supplement, Old Surety Life Insurance Company (issue-age pricing): $163.00
WellCare Classic Part D plan: $2.20
Total monthly premium: $368.10, or about $4,417 per year.
The deductibles and potential out-of-pocket:
Part A hospital deductible: $1,736 per benefit period (covered by Plan G)
Part B annual deductible: $283 (not covered by Plan G)
Part D deductible: up to $615 (out-of-pocket cap: $2,100)
With Plan G in place, the Part A hospital deductible and the unlimited Part B coinsurance exposure are largely handled. The remaining cost exposure for this individual would be the $283 Part B deductible once per year, plus drug costs up to the $2,100 Part D out-of-pocket cap, which includes the Part D deductible and all drug cost-sharing for the year.
Putting it all together:
For this individual, assuming standard medical needs and providers that accept Medicare, here is the realistic annual cost picture:
Premiums: approximately $4,417
Out-of-pocket beyond premiums: $283 (Part B deductible) + $2,100 (Part D cap) = $2,383
Total maximum annual outlay: roughly $6,800
That is not a small number, but it is a known and bounded number. For someone with significant healthcare needs or an expensive medication regimen, knowing that $4,417 to $6,800 is roughly the ceiling provides real financial predictability. Compare that to the open-ended exposure that comes with no supplement, and the value of Plan G becomes easier to see.
Your actual costs will vary based on a number of factors: whether you owe IRMAA surcharges on Part B or Part D, which Part D plan you choose based on your specific medications, and whether you select Plan G or a different Medigap option. The example above uses an issue-age priced Plan G premium and the WellCare Classic Part D plan without accounting for individual prescription needs. If you take specific medications, comparing Part D plans based on your actual drug list during the annual enrollment period each fall is worth the time. It is also worth noting that while the vast majority of providers accept Original Medicare, there are exceptions. Providers who have formally opted out of Medicare are required to inform you before providing services, but it is always worth confirming that any new provider accepts Medicare before your appointment to avoid unexpected costs.
A Brief Word on Medicare Advantage
We are not covering Medicare Advantage in depth in this article, because the variation from plan to plan and market to market makes general cost comparisons difficult. But it is worth a brief comparison for context.
Medicare Advantage, also known as Part C, bundles your Medicare benefits through a private insurer, typically an HMO or PPO. Plans frequently advertise $0 premiums beyond the base Part B cost, and many include drug coverage, dental, and vision. The tradeoff is that you are working within a network, subject to prior authorization requirements, and your actual out-of-pocket exposure depends on how much care you use and which plan you are enrolled in.
For the same 65-year-old male in the 80228 zip code, Medicare Advantage PPO options in 2026 range considerably. On the more basic end, some plans carry no additional premium beyond the standard Part B cost of $202.90 per month, but come with a maximum out-of-pocket of $5,500 for in-network services and $10,000 combined in and out-of-network. On the more comprehensive end, plans with an additional premium of around $94 per month may include a $400 health deductible, a separate drug deductible, and a significantly lower maximum out-of-pocket of $3,800 whether you stay in-network or go out.
The comparison is not straightforward because the structure is so different from Original Medicare. With Plan G, your exposure is largely fixed and predictable from the start of the year. With Medicare Advantage, your costs depend heavily on utilization, network adherence, and prior authorization outcomes.
One of the practical differences between Original Medicare and Medicare Advantage that does not always get enough attention is provider access. The vast majority of doctors and hospitals across the country accept Original Medicare. Under Original Medicare, prior authorization requirements are relatively limited compared to Medicare Advantage, and you generally do not need referrals to see specialists. Medicare Advantage plans, by contrast, typically require prior authorization for a wide range of services and often require referrals within their network structure. According to research from the Kaiser Family Foundation (KFF), Medicare Advantage enrollees have access to roughly half the physicians available to Original Medicare beneficiaries in their area, on average. That flexibility is one of the less-talked-about advantages of staying with Original Medicare, particularly for people who travel, have complex medical needs, or simply want to see any provider they choose without navigating plan-specific approval processes.
For people who are generally healthy, rarely use the healthcare system, and want to minimize fixed monthly costs, Medicare Advantage can make sense. For people who want the most comprehensive, predictable coverage with the broadest provider access, Original Medicare with Plan G is typically the stronger option.
Frequently Asked Questions
Do I have to pay for Medicare Part A?
Most people do not. If you or your spouse worked and paid Medicare taxes for at least 10 years (40 quarters), your Part A premium is $0. If you do not meet that threshold, you can still enroll in Part A, but you will pay a monthly premium.
What is the Medicare Part B premium in 2026?
The standard Part B premium is $202.90 per month in 2026. Higher-income beneficiaries pay more through a surcharge called IRMAA, which can push the monthly premium significantly higher depending on your income from two years prior.
What is IRMAA and how does it affect my Medicare costs?
IRMAA stands for Income-Related Monthly Adjustment Amount. It is a surcharge added to your Part B and Part D premiums if your income exceeds certain thresholds. Medicare looks at your tax return from two years ago to determine whether you owe it. For retirees doing Roth conversions or taking large distributions, high-income years can affect Medicare premiums down the road, which is worth factoring into your planning.
What does a Medigap policy cost?
It depends on which plan you choose, where you live, and your age. Premiums generally range from around $50 per month for leaner coverage to several hundred dollars per month for more comprehensive plans. Plan G is currently one of the most popular options because it covers nearly all out-of-pocket costs under Original Medicare, with the exception of the annual Part B deductible.
Is there a cap on what I can spend out of pocket on Medicare?
Under Original Medicare alone, there is no annual cap on the 20% you owe under Part B. Adding a Medigap policy addresses that exposure. For prescription drugs under Part D, there is now a $2,100 out-of-pocket cap in 2026. Once you hit that amount, your plan covers 100% of covered drug costs for the rest of the year.
Should I get Medicare Advantage instead of Original Medicare?
That depends on your health, your providers, and your priorities. Medicare Advantage plans can offer $0 premiums and bundled benefits, but they also come with network restrictions, prior authorization requirements, and variable cost-sharing. Original Medicare with a Medigap supplement generally offers more flexibility and predictability, and gives you access to a much broader range of providers. It is worth comparing the two approaches carefully for your specific situation.
What happens if I delay enrolling in Medicare?
Missing your initial enrollment window without a qualifying exception can result in permanent late enrollment penalties for Part A, Part B, and Part D. If you do not have at least 40 quarters of Medicare-covered employment and delay enrolling in Part A, your premium can increase by 10% and that higher premium applies for twice the number of years you delayed. The Part B penalty adds 10% to your premium for each 12-month period you were eligible but did not enroll, and it stays with you for as long as you have Medicare. The Part D penalty works similarly, adding roughly 1% of the national base premium for each month you went without creditable drug coverage. All three penalties are avoidable in most cases, either by enrolling on time or by understanding which situations qualify for a special enrollment period, such as being covered by an employer plan when you first become eligible. If you are approaching 65 and still working, it is worth verifying whether your current coverage qualifies before assuming you can delay.
