Financial independence before 65 is a goal many individuals are working toward, more seriously than ever before. Plenty of people are simply hoping to leave the workforce on their own timeline rather than the traditional one society seems to have set.
But one of the most common blind spots in early retirement planning is healthcare, and specifically what happens when you’re no longer covered by an employer’s health plan and not yet eligible for Medicare. Knowing how to prepare for the cost of Medicare, what it will actually run you each month, and how to bridge the gap between early retirement and Medicare eligibility are all pieces of a financial independence plan that too many people underestimate or skip entirely until they’re closer to 65. Getting ahead of this now, while you still have time to adjust your savings strategy, makes the whole picture clearer and more manageable.
Understanding What Medicare Actually Costs
Before you can build Medicare costs into a financial plan, you need a realistic sense of what those costs actually are. Medicare is not free, and the total expense is often higher than people expect when they think about it in abstract terms.
Part A, which covers hospital care, is premium-free for most people who’ve worked and paid Medicare taxes for at least 10 years. Part B, which covers outpatient care like doctor visits, comes with a standard monthly premium that adjusts annually. In 2026, that number is $202.90/month, though higher earners pay more through what’s called IRMAA, the Income-Related Monthly Adjustment Amount.
Part D covers prescription drugs and can add another monthly premium, as can Medigap (Medicare Supplement) or Advantage plans.
When you add it all up, a realistic estimate for a single person might run anywhere from around $300 to $600 or more per month, depending on various factors. These aren’t small numbers, especially with many on a fixed income, so they need a dedicated line in any serious financial independence plan.
The Gap Between Early Retirement and Medicare Eligibility
Here’s where early retirement planning can get complicated. Medicare eligibility for most people starts at 65. If you’re planning to retire at 55, 58, or 62, you’re looking at a gap of anywhere from three to ten years during which you need to cover your own health insurance costs entirely.
ACA marketplace plans are the most common solution, and depending on your projected retirement income, you might qualify for premium tax credits that reduce your costs.
The gap years also represent a period of healthcare cost uncertainty that’s worth building a specific buffer for in your financial plan. Health issues that arise in your late 50s or early 60s, before Medicare eligibility, are covered by whatever private insurance you have—but that coverage might come with higher out-of-pocket costs than Medicare, narrower networks, or other limitations depending on what you choose.
IRMAA: The Surprise Charge for Higher Earners
If your retirement income is above certain thresholds, you’ll pay more for Medicare than the standard premium. This is IRMAA—the Income-Related Monthly Adjustment Amount—and it applies to both Part B and Part D premiums.
IRMAA is based on your income from two years prior. So, your 2026 Medicare premiums are based on your 2024 income. For people transitioning from high-earning careers to retirement, this means that even after you’ve stopped working, your Medicare premiums might reflect your former income for a year or two before adjusting downward.
The good news is that you can appeal IRMAA if your income has significantly decreased due to a life-changing event like retirement. The Social Security Administration handles these appeals, and they’re worth pursuing if your income drops substantially.
Building Healthcare Into Your Retirement Budget
Treat healthcare as its own budget category with its own dedicated projections rather than lumping it into general living expenses.
Start with what you know: estimated Medicare premiums for Part B, Part D, and any Medigap or Medicare Advantage coverage. Add realistic estimates for out-of-pocket costs, such as dental, vision, hearing, and the cost-sharing that Medicare doesn’t cover. Then add a buffer for unexpected medical expenses, because unexpected things happen.
Healthcare costs historically increase faster than general inflation, which means your healthcare budget line in year one of Medicare enrollment shouldn’t be used as a flat projection for all subsequent years.
Health Savings Accounts
If you’re still working and covered by a high-deductible health plan, a Health Savings Account is one of the most valuable tools available for building a healthcare cost cushion before 65, and for funding Medicare costs after.
HSA contributions are tax-deductible, the money grows tax-free, and withdrawals for qualified medical expenses are also tax-free. That triple tax advantage makes HSAs uniquely powerful for healthcare savings. Contributions must stop once you enroll in Medicare, but accumulated funds can continue to be used tax-free for qualified expenses including Medicare premiums, out-of-pocket costs, dental, vision, and long-term care insurance premiums.
Long-Term Care
No honest discussion of Medicare costs in a financial independence plan is complete without addressing long-term care. Medicare covers very limited long-term care, such as some skilled nursing facility care under specific conditions, and home health care only when it’s skilled and medically necessary. The ongoing custodial care that many people eventually need, help with daily activities over months or years, is not covered by Medicare.
The financial exposure here is huge. A multi-year need for this level of care can deplete even well-funded retirement savings.
Address this risk, either through some type of long-term care insurance or specific self-funding strategies. The point is, doing it before you retire gives you the most options at the most reasonable cost.
Social Security Timing
For early retirees, Social Security timing interacts with Medicare planning in ways worth understanding. You can’t claim Social Security before 62, and delaying past 62 increases your eventual benefit. If you retire before 62 and bridge the gap with savings, you have flexibility when you start Social Security.
For people with significant retirement savings, delaying Social Security until their full retirement age or the max age 70 to increase their benefit is a common strategy. If you’re in this camp, understand how your income sources during the delay period interact with both marketplace insurance costs and eventual Medicare premiums so you have clarity about the overall picture.
Starting the Planning Process Early
The common thread running through all of this is timing. Healthcare costs in retirement, both before and after Medicare eligibility, are more manageable when you start planning for them in advance rather than at the last minute. The people who navigate this transition most smoothly are generally those who treat Medicare and healthcare costs as a specific, researched line item in their financial independence plan rather than a vague future expense to figure out later.
If you’ve got some time before your target retirement date, you have real runway to adjust your savings rate and think through your financial strategies. Use that time well, and healthcare costs will become a planned part of your retirement picture rather than the surprise that derails it.
