Health Insurance in Early Retirement: The Real Options

The math on an early retirement budget usually falls apart in one place first: health insurance. Once you leave a job, you leave employer coverage, and the replacement options, marketplace plans, COBRA, or self-pay, can run into five figures a year for a family, before you've accounted for deductibles. Getting this piece wrong is often what turns a promising FIRE plan into an unworkable one.

There are three real paths, and they interact with each other more than most retirement guides let on.

The ACA marketplace, and why your income matters more than your health

For most early retirees, the ACA marketplace is the default option, because coverage is guaranteed-issue: insurers can't deny you or charge more for pre-existing conditions. Premiums are based on your plan, age, location, and household size, but the amount you actually pay often depends heavily on a premium tax credit, which is calculated against your household income as a percentage of the federal poverty level. HealthCare.gov explains the mechanism: the lower your MAGI (modified adjusted gross income) relative to the poverty line for your household size, the larger the subsidy, generally, up to eligibility limits and thresholds that change from year to year.

This is where early retirees get an odd kind of leverage that current workers don't have. If your income now comes from taxable investment withdrawals rather than a salary, you have real control over your reported MAGI. You decide how much to realize in capital gains, how much (if any) to convert from traditional to Roth accounts, and how much to draw down from principal versus already-taxed savings. Pushing MAGI down, within reason, can move you into a lower premium bracket or make you eligible for a larger credit.

Concretely: a household drawing $60,000 a year from a mix of sources has real choice in how that $60,000 shows up as income. Selling shares that are mostly return of your own original investment (basis) generates little reportable gain; selling shares with a large embedded gain generates a lot. Living partly off already-taxed savings or Roth contributions (which aren't included in MAGI at all) versus traditional IRA withdrawals (which are fully included) changes the same spending number into very different MAGI figures. None of this is about hiding income. It's about recognizing that "how much you spend" and "what counts as MAGI" aren't the same number, and the gap between them is where planning happens.

A worked, illustrative example: managing MAGI across income bands

The dollar figures below are illustrative only. They are not this year's actual federal poverty guidelines or applicable percentage table; check HealthCare.gov for the current numbers before budgeting around a specific subsidy. The point of the example is the shape of the relationship between MAGI and subsidy, not the specific dollar amounts.

Say a two-person household is targeting $55,000 in reported MAGI for the year, and, for illustration only, the federal poverty guideline for a household of two is a round $20,000 (the real figure changes annually and by household size). $55,000 works out to roughly 275% of that illustrative poverty line.

Under the ACA's premium tax credit structure, the share of income a household is expected to contribute toward the "benchmark" (second-lowest-cost silver) plan premium rises as income rises as a percentage of the poverty line. Using illustrative, rounded bands to show the shape of the curve, not this year's real percentages:

• Near 150% of the poverty line: an illustrative expected contribution of roughly 2% to 4% of income.
• Near 200% of the poverty line: an illustrative expected contribution of roughly 4% to 6% of income.
• Near 275% of the poverty line, this household's example: an illustrative expected contribution of roughly 6% to 7% of income.
• Near 400% of the poverty line: an illustrative expected contribution of roughly 8% to 9% of income, near the top of the sliding scale.

Now put a dollar figure on it. Say the benchmark silver plan for this household costs an illustrative $14,000 a year in full premium.

• At $55,000 MAGI (roughly 275% of the illustrative poverty line), an illustrative 6.5% expected-contribution rate works out to about $3,575 a year paid toward premiums. The premium tax credit would cover the remaining roughly $10,425 of the $14,000 illustrative premium.
• If the same household instead managed its withdrawals down to $40,000 MAGI (roughly 200% of the illustrative poverty line), by drawing more from Roth contributions or already-taxed savings and less from traditional-account withdrawals or realized capital gains, an illustrative 5% expected-contribution rate works out to about $2,000 a year. The credit would then cover roughly $12,000 of the same $14,000 premium.

That's an illustrative difference of about $1,575 a year in subsidy for managing MAGI down by $15,000, without necessarily changing how much the household actually spends. It's why the mix of accounts a retiree draws from matters as much as which plan they pick: the same $55,000 (or $40,000) of real-world spending can show up as very different MAGI depending on whether it's funded from Roth withdrawals, basis, or taxable capital gains and traditional IRA distributions.

The specific income thresholds, subsidy percentages, and any "cliffs" in the formula change with legislation and are not something to memorize from an article. Check HealthCare.gov or your marketplace's current-year figures directly before you build a budget around a specific subsidy number.

A note on plan tiers and network size

Marketplace plans are grouped into metal tiers (bronze, silver, gold, platinum) that describe the split between what you pay in premiums versus what you pay out of pocket when you use care, not the quality of the doctors in the network. Bronze plans have the lowest premium and the highest deductible; silver and above shift more of the cost into the monthly premium and less into out-of-pocket spending at the point of care. One detail specific to early retirees: cost-sharing reductions, which lower your deductible and out-of-pocket maximum further, are only available on silver-tier plans and only below certain income levels. That's another reason your MAGI target matters beyond just the premium tax credit, and another detail to check against current HealthCare.gov figures rather than assume. Network size also varies more than people expect between marketplace insurers in the same area; if you have an existing doctor or specialist you want to keep, confirm they're in-network for the specific plan, not just the same insurer's employer-sponsored plans you may have used before.

COBRA: a short, expensive bridge

COBRA lets you keep your former employer's exact health plan for a limited period, typically up to 18 months, after leaving the job, as described by the Department of Labor. The upside is continuity: same plan, same network, same coverage, no medical underwriting. The downside is cost: you now pay the full premium, the portion your employer used to cover included, plus often an administrative fee. For most people it's meaningfully more expensive per month than a subsidized marketplace plan, which makes it better suited as a short-term bridge between jobs than a multi-year early retirement strategy.

HSA: not insurance, but a real part of the plan

A Health Savings Account only exists alongside a qualifying high-deductible health plan, and you can only contribute to it during years you're covered by one, per IRS Publication 969. What makes it valuable for early retirees is the combination of three tax breaks: contributions are deductible (or pre-tax through payroll), growth is tax-free, and withdrawals for qualified medical expenses are tax-free at any age, with no time limit on when you reimburse yourself. Save your medical receipts from your working years, let the HSA balance grow for a decade, and you can reimburse yourself tax-free in early retirement for expenses paid years earlier, effectively a second retirement account that happens to be earmarked for healthcare. After 65, non-medical withdrawals are allowed too, taxed as ordinary income but without the earlier penalty.

You lose HSA contribution eligibility the moment you're on a non-high-deductible plan or on Medicare, so the years right before early retirement are usually the last chance to max it out. If you're planning an exit date, treat HSA contributions as one of the last things to optimize before you go, not an afterthought.

What changes at 65

Health insurance planning for early retirement is really planning for a specific, known-length gap: from whenever you leave employer coverage until you become eligible for Medicare at 65. That gap might be two years or twenty-five, but it has an endpoint, which is worth remembering when the marketplace math feels open-ended. Medicare itself isn't free. It has its own premiums, deductibles, and enrollment timing rules, and getting Medicare enrollment timing wrong carries its own penalties, similar in spirit to (though separate from) the retirement-account rules covered elsewhere on this site. That's a big enough topic to deserve its own research when you're a few years out; the point here is just that the marketplace/COBRA/HSA decision you make at 45 or 50 isn't a permanent one, it's a bridge to a different system that takes over at 65.

Decision framework

• Estimate your post-retirement MAGI before you estimate your premium. The subsidy math runs off MAGI, not off your net worth or spending. Run the numbers with your actual planned withdrawal mix (how much Roth vs. traditional vs. taxable) before assuming a marketplace plan will be affordable, or unaffordable.
• Use COBRA as a stopgap, not a plan. It's most useful for a short gap, a mid-year job exit before open enrollment, for instance, where you need continuous coverage for a few months rather than a permanent early-retirement solution.
• Decide whether a high-deductible HSA-eligible plan fits your risk tolerance. It usually has the lowest premium and the HSA tax benefits, but a higher deductible means more exposure if a real medical event happens in a given year. That trade-off is personal, not universal.
• Revisit every open enrollment period. Marketplace plans, subsidy rules, and your own income picture (especially if you're doing Roth conversions that bump MAGI in a given year) can all change year to year. This isn't a set-it-and-forget-it decision.

Limits and exceptions

Subsidy formulas, income thresholds, and plan availability vary by state and by year. Some states run their own exchanges with different rules than the federal marketplace. Large one-time income events (a Roth conversion, a home sale, a big capital gain) can push your MAGI into a range that reduces or eliminates a subsidy for that year, so it's worth modeling major transactions and your health coverage together, not separately. If you have a chronic condition with significant ongoing costs, run the numbers on total expected out-of-pocket cost, not just premium, before choosing a high-deductible plan for the HSA benefit alone. And none of this is legal or tax advice for your specific household. A marketplace navigator (free, and listed on HealthCare.gov) or a fee-only planner familiar with ACA subsidy planning can model your actual numbers.

There's also a real risk in over-optimizing for subsidy eligibility at the expense of the rest of the plan. Suppressing income too aggressively to chase a bigger premium tax credit can mean delaying Roth conversions you actually needed to do on a longer timeline, or leaving a large traditional IRA balance to compound into a bigger required-minimum-distribution problem later. Treat the health insurance MAGI target as one input into the broader tax and withdrawal plan, not the variable everything else bends around.

This is also one of the clearest places where taxes in early retirement and health coverage planning aren't really separate problems: the same MAGI number drives both.
