Healthcare in Early Retirement

The Gap Between Your Last Paycheck and Medicare

Ask anyone planning early retirement what keeps them up at night, and healthcare tops the list. There's a reason: employer-sponsored health insurance ends when you leave your job, but Medicare doesn't start until age 65. If you retire at 50, that's 15 years of coverage you need to figure out on your own. At 45, it's 20 years. And healthcare costs aren't small — a 55-year-old couple can easily spend $1,500 to $2,500 per month on premiums alone before subsidies, depending on location and plan tier.

This isn't a reason to abandon early retirement plans. It is a reason to plan for healthcare as carefully as you plan your investment portfolio. The options are real, the math is workable, and the strategies in this article can reduce costs dramatically. But you need to understand them before you hand in your resignation.

COBRA: Bridge Coverage from Your Former Employer

The Consolidated Omnibus Budget Reconciliation Act (COBRA) gives you the right to continue your employer's group health plan for up to 18 months after you leave (26 months if you're disabled). The coverage is identical to what you had as an employee — same network, same benefits, same plan.

The catch: you pay the entire premium yourself. When you were employed, your company typically covered 70-80% of the premium cost. Under COBRA, you pay 100% of the total premium plus a 2% administrative fee. That employer-subsidized $400/month plan might actually cost $1,600/month when you see the full price.

COBRA is most useful in two situations: when you have ongoing medical treatment with in-network providers you don't want to switch, or when you need a few months of coverage while you set up an Affordable Care Act (ACA) marketplace plan. You have 60 days to elect COBRA after losing coverage, and you can drop it at any time (though you can't re-enroll once you drop it).

The ACA Marketplace: The Primary Option for Early Retirees

For most early retirees, the ACA marketplace is the main source of health insurance between retirement and Medicare. The Affordable Care Act (ACA) created state and federal health insurance exchanges where individuals can buy coverage regardless of pre-existing conditions. Plans are organized into metal tiers based on how much of your medical costs the plan covers on average:

• Bronze: Lowest premiums, highest out-of-pocket costs. The plan covers about 60% of costs on average. Best if you're healthy and want catastrophic protection.
• Silver: Moderate premiums and out-of-pocket costs. Covers about 70% on average. Uniquely eligible for cost-sharing reductions (more on this below).
• Gold: Higher premiums, lower out-of-pocket costs. Covers about 80% on average.
• Platinum: Highest premiums, lowest out-of-pocket costs. Covers about 90% on average. Not available in all markets.

A critical detail for early retirees: cost-sharing reductions (CSRs) are only available on silver plans. If your income is between 100% and 250% of the federal poverty level (FPL), a silver plan's deductibles, copays, and out-of-pocket maximums are reduced — sometimes dramatically. A silver plan with CSRs can have better effective coverage than a gold or platinum plan at a fraction of the cost. This makes silver the default choice for most subsidy-eligible early retirees.

How Premium Tax Credits Work

The ACA provides premium tax credits (PTCs) to reduce monthly health insurance premiums. The amount you receive depends on your modified adjusted gross income (MAGI) relative to the federal poverty level (FPL). The FPL varies by household size and is updated annually — for a single person in 2025, it's approximately $15,650; for a couple, approximately $21,150.

Here's how it works: the government sets a maximum percentage of your income that you should pay for a benchmark silver plan (the second-lowest-cost silver plan in your area). If the actual premium exceeds that percentage, the difference is your premium tax credit. At lower incomes, the expected contribution is near zero. As income rises, you're expected to pay a larger percentage.

At incomes between 100% and 150% of the FPL, you might pay $50-$100/month for a silver plan. Between 150% and 200% of FPL, perhaps $150-$300/month. Between 200% and 400% of FPL, the subsidies decrease but remain meaningful. Above 400% of FPL, subsidy availability depends on current legislation — the enhanced subsidies introduced in 2021 have been extended multiple times but are not permanent.

MAGI Management: The Early Retiree's Most Powerful Tool

Modified adjusted gross income (MAGI) for ACA purposes includes wages, traditional IRA/401(k) withdrawals, Roth conversion amounts, taxable interest, dividends, and realized capital gains. It does not include Roth IRA withdrawals (of contributions or qualified earnings), return of basis from taxable accounts, or loans against assets.

This creates a planning opportunity. In early retirement, you choose which accounts to draw from. By carefully selecting your income sources, you control your MAGI — and therefore your ACA subsidies. The strategies:

• Roth IRA withdrawals: Contributions come out tax-free and don't count toward MAGI at any age. If you've been contributing to a Roth for years, this is your most flexible income source.
• Taxable brokerage account — return of basis: When you sell investments in a taxable account, only the gain counts as income. If you bought a stock for $50,000 and it's now worth $55,000, selling it adds only $5,000 to your MAGI. Selling lots with minimal gains keeps MAGI low.
• Tax-lot selection: If you have multiple purchases of the same investment at different prices, sell the lots with the highest cost basis first (specific identification method) to minimize realized capital gains.
• Roth conversions — with caution: Converting traditional IRA money to a Roth IRA counts as income in the year you convert. This can be useful for long-term tax planning, but each dollar converted adds a dollar to your MAGI. Balance conversion amounts against your subsidy thresholds.

The Health Savings Account (HSA) as a Healthcare Bridge

A health savings account (HSA) is a tax-advantaged account available to people enrolled in a high-deductible health plan (HDHP). Contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free — the only account in the tax code with a triple tax advantage.

For early retirement planning, the HSA has a specific role: covering out-of-pocket medical costs without adding to your MAGI. When you pay a $2,000 deductible or a $500 specialist bill from your HSA, that money doesn't appear on your tax return. It doesn't affect your ACA subsidy eligibility. It's invisible to the income calculations.

The strategy many early retirees use during their working years: contribute the maximum to their HSA, invest the balance in index funds, and pay current medical expenses out of pocket (keeping receipts). By retirement, the HSA has grown into a dedicated medical fund. A couple maximizing HSA contributions for 10-15 years before retirement can accumulate $150,000-$250,000 or more, depending on investment returns — enough to cover deductibles and out-of-pocket costs for years.

After age 65, HSA funds can be withdrawn for any purpose (not just medical) — you'll pay income tax on non-medical withdrawals, similar to a traditional IRA, but there's no penalty. For medical expenses, withdrawals remain tax-free at any age.

Healthcare Sharing Ministries: What They Are and What They're Not

Healthcare sharing ministries (HCSMs) are organizations where members share medical costs according to a set of guidelines. Members pay a monthly "share" amount (similar to a premium, typically $200-$600/month for a family), and when a member has a medical need, other members' contributions help cover the cost.

Some early retirees consider HCSMs because of lower monthly costs compared to unsubsidized ACA premiums. But there are significant differences from actual insurance:

• No guarantee of payment. HCSMs are not insurance and are not regulated as insurance. They are not legally obligated to pay your medical bills. Most operate in good faith, but "eligible for sharing" is not the same as "covered."
• Pre-existing condition limitations. Most HCSMs exclude or limit sharing for pre-existing conditions, sometimes for years after joining. The ACA prohibits insurers from doing this — HCSMs are exempt from that rule because they're not insurers.
• Annual and lifetime caps. Many HCSMs have per-incident or annual sharing limits. A serious illness or major surgery can exceed these limits, leaving you responsible for the balance.
• Lifestyle requirements. Most HCSMs require members to follow specific religious or lifestyle guidelines (no tobacco, limited alcohol, agreement with a statement of faith). Some exclude costs related to conditions they consider lifestyle-related.
• No network negotiated rates. Insurance companies negotiate discounted rates with providers. HCSM members are often billed at full price and must negotiate their own discounts or pay the difference.

HCSMs may work for healthy early retirees with substantial emergency funds who understand and accept these limitations. They are not a substitute for comprehensive health insurance, especially for anyone with chronic conditions or a family history of serious illness.

Budgeting for Healthcare Costs

Healthcare costs in early retirement have two components: premiums (what you pay monthly for coverage) and out-of-pocket costs (deductibles, copays, coinsurance, prescriptions, dental, vision). Both vary significantly by age, location, family size, and health status.

Rough monthly budget ranges for ACA marketplace plans before subsidies (2025 estimates):

• Single, age 40-49: $400-$700/month premium for a silver plan. Add $200-$400/month for average out-of-pocket costs.
• Single, age 50-59: $600-$1,000/month premium. Add $250-$500/month for out-of-pocket costs.
• Single, age 60-64: $800-$1,400/month premium. Add $300-$600/month for out-of-pocket costs.
• Couple, age 55: $1,200-$2,000/month combined premium. Add $400-$800/month for combined out-of-pocket costs.

With subsidies, these numbers can drop dramatically. A couple with MAGI at 200% of the FPL might pay $300-$500/month total for a silver plan. At 150% of FPL, premiums can be under $200/month. This is why MAGI management is so important — the difference between managed and unmanaged income can be $10,000-$20,000 per year in healthcare costs.

Don't forget costs that ACA plans don't cover well: dental, vision, and hearing. Budget $1,000-$3,000 per person per year for these, depending on your needs. Dental work in particular can be expensive — a single crown can cost $1,000-$2,000 without dental coverage.

The Medicare Transition at 65

Medicare eligibility at 65 is the light at the end of the early retirement healthcare tunnel. Understanding the parts and enrollment windows matters because mistakes can result in permanent premium penalties.

Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health care. Premium-free for most people (anyone who paid Medicare taxes for 10+ years through employment). There's a per-benefit-period deductible (~$1,632 in 2025) but no monthly premium for most enrollees.

Part B (Medical Insurance): Covers doctor visits, outpatient care, preventive services, lab tests, ambulance services, and durable medical equipment. Monthly premium of approximately $185/month in 2025, with higher premiums for higher-income enrollees (income-related monthly adjustment amount, or IRMAA). Part B has an annual deductible (~$257 in 2025) and typically covers 80% of approved costs after the deductible.

Part D (Prescription Drug Coverage): Covers prescription medications through private insurance plans. Premiums vary by plan and location (typically $15-$80/month). Also subject to IRMAA surcharges for higher earners.

Medigap (Medicare Supplement): Private insurance that covers the gaps in Original Medicare — the 20% that Part B doesn't pay, hospital deductibles, and excess charges. Medigap plans are standardized by letter (Plan G and Plan N are the most popular). Monthly premiums range from $100-$300 depending on plan, age, and location. You have a guaranteed-issue period during the first 6 months after enrolling in Part B — during this window, no insurer can deny you or charge more for pre-existing conditions.

Medicare Advantage (Part C): An alternative to Original Medicare + Medigap. Private insurers offer bundled plans that include Parts A, B, and usually D, often with additional benefits (dental, vision, hearing, gym memberships). Many have $0 premiums beyond the standard Part B premium. The trade-off: network restrictions, prior authorization requirements, and potential out-of-pocket costs that Medigap would have covered.

Healthcare Planning Checklist for Early Retirement

Use this checklist when building healthcare into your FIRE plan:

1. Estimate your gap. How many years between your target retirement age and 65? Each year needs coverage.
2. Check ACA plan costs in your area. Visit healthcare.gov and enter your expected retirement MAGI. Note the premium and out-of-pocket maximum for silver plans.
3. Model your MAGI. Map out which accounts you'll draw from each year. Calculate the resulting MAGI and the corresponding ACA subsidy level. Are you in the cost-sharing reduction range?
4. Build a Roth conversion ladder. If most of your savings are in traditional accounts, start Roth conversions 5+ years before retirement to create a pool of tax-free, MAGI-free withdrawals.
5. Maximize your HSA. If you have access to a high-deductible health plan (HDHP), contribute the maximum and invest the balance. Pay current medical expenses out of pocket. Save receipts — you can reimburse yourself from the HSA at any time in the future.
6. Add dental, vision, and hearing costs. ACA plans have limited or no coverage for these. Budget separately.
7. Plan the COBRA bridge. Decide in advance whether you'll use COBRA (for care continuity) or go straight to the ACA marketplace. Compare the costs using your actual employer COBRA rate.
8. Budget for healthcare cost inflation. Healthcare costs have historically risen faster than general inflation — roughly 5-7% per year. A plan that costs $600/month today may cost $1,000/month in 10 years.
9. Learn Medicare basics before 65. Understand enrollment windows, the Medigap guaranteed-issue period, and IRMAA thresholds. Mark your calendar for your initial enrollment period.
10. Stress-test your plan. What happens if ACA subsidies change? What if you have a major medical event in year two? What if healthcare inflation runs higher than expected? Build a buffer.
