Healthcare Before 65: The Early Retiree's Bridge to Medicare

The number most FIRE plans underestimate. Here's what it actually costs and how to plan around it.

The gap you need to bridge

Medicare starts at 65. If you retire at 52, you have 13 years of health coverage to figure out on your own. At 45, it's 20 years. This isn't a footnote — for many early retirees, healthcare is the single largest line item between retirement and Medicare eligibility, easily $150,000–$400,000 cumulative depending on age, location, and how well you manage your income.

Employer coverage ends when you leave. COBRA extends it temporarily. After that, the ACA marketplace is the primary option for most people. Understanding how these interact with your income — specifically your Modified Adjusted Gross Income (MAGI) — is the core of early-retirement healthcare planning.

Option 1 — COBRA: temporary continuation of employer coverage

COBRA lets you continue your employer's group health plan after leaving a job. You pay the full premium — both the employee and employer share — plus a 2% administrative fee.¹

• Duration: 18 months for job termination or hours reduction. 36 months for divorce, death of covered employee, or a dependent aging off the plan. Up to 29 months with a Social Security disability determination.²
• Cost in 2026: The national average premium is roughly $560/month per covered person — but group plan costs vary widely. Many early retirees see $700–$1,400/month for individual coverage and $1,600–$2,400/month for a couple once the employer stops subsidizing their share.³
• When it makes sense: If you have a serious ongoing health issue, a specialist relationship you want to preserve, or a high-deductible plan that's already met its out-of-pocket max for the year. Also useful as a bridge if you're retiring mid-year and ACA open enrollment timing doesn't work in your favor.
• The hard limit: COBRA runs out at 18 months. If you retire at 52, you're still 11.5 years short of Medicare after COBRA ends. It buys time, not a full solution.

Option 2 — ACA marketplace plans: the main bridge for most early retirees

The ACA marketplace (HealthCare.gov and state equivalents) is how most early retirees cover the years between COBRA and Medicare. Under IRC § 36B, households with income between 100% and 400% of the Federal Poverty Level (FPL) qualify for premium tax credits (PTCs) that reduce their monthly premium.

The 2026 landscape: enhanced subsidies expired

This change increased unsubsidized marketplace premiums dramatically. For a 60-year-old in 2026, the national average unsubsidized premiums are:⁵

• Lowest-cost Bronze plan: ~$969/month (~$11,625/year)
• Benchmark Silver plan: ~$1,326/month (~$15,914/year)
• Lowest-cost Gold plan: ~$1,306/month (~$15,672/year)

These are per person costs without subsidies. A couple at age 60 could face $2,600–$3,000/month in unsubsidized premiums — a number that reshapes what "enough" means for a retirement portfolio.

The 400% FPL cliff

For 2026, the individual income threshold for subsidy eligibility is $63,840 (400% of the 2026 FPL of $15,960 for a single person).⁶ Cross that line by $1 and you lose all subsidy. For a 60-year-old whose benchmark silver plan costs $15,914/year, the difference between $63,839 and $64,000 MAGI is the entire ~$15,000/year premium cost falling onto you.

OBBBA also eliminated the caps on premium tax credit repayment that previously protected lower-income enrollees from large year-end reconciliation bills. If your actual MAGI exceeds your projected income, you now owe the full subsidy back — no ceiling on the repayment.⁷ Accurate income projection matters more in 2026 than in any prior year.

The MAGI coordination problem

This is where early retirement healthcare planning becomes genuinely complex — and where most people need a specialist.

Early retirees often have controllable income. Unlike employees with W-2 wages, a person drawing from a portfolio can often choose how much taxable income to recognize in a given year. That's a lever most people don't have. But pulling it wrong can cost tens of thousands of dollars in healthcare premiums.

What counts toward ACA MAGI

ACA MAGI = AGI + tax-exempt bond interest + excluded foreign income. Key components for early retirees:

• Roth conversions: Converting a traditional IRA to Roth is taxable income that raises MAGI — every dollar converted counts.
• Capital gains and dividends: Realized long-term capital gains and qualified dividends are included. Unrealized gains on index funds sitting in a taxable account do not count.
• SEPP / 72(t) distributions: Substantially equal periodic payments from a traditional IRA are ordinary income and count toward MAGI.
• Roth IRA principal withdrawals: Withdrawal of your original contributions (not earnings, not conversions under 5 years) is tax-free and does not count toward MAGI. This is one of the cleanest income sources for ACA MAGI management.
• HSA distributions for qualified expenses: Tax-free, not included in MAGI.

The Roth ladder trade-off

The Roth conversion ladder is a core early-retirement access strategy — convert traditional IRA funds to Roth over 5 years to enable penalty-free withdrawals before 59½. But each conversion raises MAGI. If you're converting $50,000/year and living on $60,000/year, your MAGI is at least $50,000 — possibly above the 400% FPL cliff if you're also realizing capital gains.

The strategy most advisors recommend: sequence your withdrawals to target a specific MAGI band. In your first 5 years of early retirement (before the ladder is ready), lean on taxable brokerage accounts and Roth principal first to minimize MAGI and maximize ACA subsidies. Once the ladder is flowing, calibrate conversions to stay below $63,840 (or your specific state's relevant thresholds). Post-65, IRMAA brackets for Medicare replace ACA subsidies as the main cliff to manage.

Option 3 — spouse's employer plan

If a spouse continues working, getting on their employer plan is almost always the best option. Employer group plan premiums are subsidized, tax-advantaged (premium deducted pre-tax), and typically offer better networks than ACA marketplace plans at comparable cost. If one partner's plan is available, exhaust this option before modeling ACA scenarios.

Option 4 — part-time work for benefits ("barista FIRE")

Some employers offer benefits at 20 hours/week. Costco, Starbucks, and REI are commonly cited examples. This approach — sometimes called "barista FIRE" or "coast FIRE" — reduces sequence-of-returns risk early in retirement while solving the healthcare problem. The trade-off: reduced flexibility and partial return to employment, which some people embrace and others resist.

What to budget

Rule of thumb by situation:

• Income managed below 400% FPL, with ACA subsidies: $2,000–$8,000/year per person, depending on income, age, and plan selected.
• Income above 400% FPL, no subsidy, age 50–59: $6,000–$10,000/year per person (age 50 is significantly cheaper than 60).
• Income above 400% FPL, no subsidy, age 60–64: $11,000–$18,000/year per person (ACA allows up to 3× the baseline rate for age).
• COBRA (if group plan was good): $6,000–$12,000/year per person for 18 months, then transitions to marketplace.

Budget a 5–10% annual increase in healthcare costs. Premiums have consistently outpaced general inflation. A 55-year-old retiring today should model at least 10 years of healthcare cost growth before Medicare.

A real planning scenario

Consider this case: retiring at 52, single, $2.5M ($1.8M traditional IRA, $500K Roth, $200K taxable). Annual spending target: $80,000. No spouse. 13 years to Medicare.

• Year 1–1.5 (COBRA): $750/month = ~$13,500. Keeps current specialist relationships, buys time to set up ACA.
• Years 1.5–13 (ACA): Goal is to keep MAGI at ~$55,000 (roughly 345% of individual FPL) to qualify for modest PTC. This requires careful coordination: draw $55,000 from Roth principal (no MAGI impact), tap taxable account for remainder, limit early Roth conversions to amounts that keep MAGI in target range.
• At 57: The Roth conversion ladder started at retirement is fully funded. Can begin taking those conversion amounts penalty-free.
• Healthcare cost: With MAGI at 345% FPL and ACA subsidies, approximate cost ~$5,000–$8,000/year for a silver plan vs. $15,000+/year without subsidies. Over 11.5 post-COBRA years, that's a $80,000–$115,000 difference — enough to fund nearly 1.5 years of spending.

Getting this sequence wrong — blowing past the 400% FPL cliff with an unnecessary Roth conversion in year one — could cost $100,000+ cumulatively over the healthcare bridge.
