Why Healthcare Is the Hardest Budget Line in Early Retirement
Healthcare costs in early retirement have three properties that make them especially difficult to plan for. First, they're large — often the single largest budget line for people 55–64. Second, they're uncertain — premiums and out-of-pocket costs change annually, and health status can shift unexpectedly. Third, they're mostly invisible to most workers — employer-sponsored coverage hides the true cost, creating a systematic underestimation problem at retirement planning time.
The Kaiser Family Foundation's 2024 Employer Health Benefits Survey found that the average annual employer-sponsored health insurance premium for family coverage was $23,968 in 2024. The average employee contribution was $6,296 — meaning employers paid $17,672, or 74% of the total. Most employees have no idea their plan actually costs $24,000/year because they only see the $525/month deduction from their paycheck.
Early retirees see all of it. Every dollar of it. This is the core of why healthcare catches people by surprise.

Your Three Options Between Retirement and 65
When you leave employer-sponsored coverage, you have three primary options depending on your age, income, and situation:
Option 1: COBRA Continuation Coverage
COBRA (Consolidated Omnibus Budget Reconciliation Act) lets you continue your existing employer health plan for up to 18 months after a qualifying event — in this case, voluntary retirement or job loss. You pay the full premium (employer + employee share) plus a 2% administrative fee.
COBRA's main advantages: immediate, continuous coverage with no gap; same network, same doctors, same prescription benefits. If you're in the middle of treatment, active specialty care, or have a complex health situation, COBRA's continuity can be worth the higher cost for the initial transition period.
COBRA's disadvantages: it's expensive (you're now paying what your employer was subsidizing), and the 18-month limit means it's a bridge, not a solution. At 18 months, COBRA expires regardless, and you'll need another plan.
When to use COBRA: when you're within 18 months of Medicare eligibility (retire at 63½, COBRA covers you to 65), when you have in-progress treatments or specialty care that would be disrupted by a network change, or when your retirement happens mid-year and you want to avoid a marketplace enrollment during a complex financial planning period.
Option 2: ACA Marketplace Plans
ACA marketplace plans are the primary long-term solution for most early retirees who need coverage from retirement to Medicare. Since the ACA prohibits denying coverage or charging more based on health status, marketplace plans are available to everyone regardless of pre-existing conditions — a foundational protection for early retirees.
Premiums are based on age (older enrollees pay more, up to 3:1 compared to younger adults), location, tobacco use, and the metal tier of the plan. A 60-year-old non-smoker in an average-cost market might pay $900–$1,300/month for a silver plan before subsidies.
After subsidies, the cost can be dramatically lower — or near zero for early retirees who manage their taxable income carefully. This is the most important strategic opportunity in early retirement healthcare planning.
Option 3: Spouse's Employer Plan
If your spouse continues working with employer coverage, you can be added to their plan (typically at open enrollment or as a qualifying life event). This is often the most cost-effective option by far — you pay the employee family premium, which averages about $6,300/year, while the employer covers the rest. If your spouse has good coverage and isn't planning to retire immediately, remaining on their plan until Medicare eligibility is a legitimate strategy worth modeling explicitly in your early retirement plan.
How ACA Subsidies Work — And How to Maximize Them
Premium Tax Credits (PTCs) — ACA subsidies — are the single most important tool for managing healthcare costs in early retirement. Understanding how they work is worth spending time on.
Subsidies are based on your Modified Adjusted Gross Income (MAGI) as a percentage of the Federal Poverty Level (FPL). Coverage for 2026 is measured against the 2025 poverty guidelines (48 states and DC; Alaska and Hawaii are higher):
- Individual FPL: $15,650 (400% = $62,600)
- Couple FPL: $21,150 (400% = $84,600)
- Family of 4 FPL: $32,150 (400% = $128,600)
The subsidy caps your premium contribution for the benchmark silver plan at a percentage of income that rises with income. The 2026 percentages (the pre-2021 schedule, indexed — the larger enhanced subsidies expired after 2025):
| Income (% of FPL) | Approx. Income (Individual) | Premium Cap |
|---|---|---|
| 100%–133% | $15,650–$20,815 | 2.10% of income |
| 133%–150% | $20,815–$23,475 | 3.14%–4.19% of income |
| 150%–200% | $23,475–$31,300 | 4.19%–6.60% of income |
| 200%–250% | $31,300–$39,125 | 6.60%–8.44% of income |
| 250%–300% | $39,125–$46,950 | 8.44%–9.96% of income |
| 300%–400% | $46,950–$62,600 | 9.96% of income |
| Above 400% | Above $62,600 | No credit — you pay the full premium |
Within each band the percentage rises in a straight line. Below 100% of FPL there is generally no credit; in states that expanded Medicaid, income under 138% usually means Medicaid instead.
Your subsidy is the difference between the full benchmark silver plan premium and your income-based cap. If the benchmark silver plan costs $1,000/month and you are single with $60,000 of MAGI (383% of FPL), your expected contribution is 9.96% of income — $498/month — so your subsidy is $502/month, or $6,024/year that the federal government pays directly to your insurer. At $62,601 of MAGI the subsidy is zero.
The 400% cliff is back in 2026. From 2021 through 2025, Congress temporarily removed the upper income limit, so households above 400% of FPL could still qualify. That expansion ended with 2025. In 2026, one dollar of MAGI above 400% of FPL removes the entire credit, and for tax years after 2025 there is no cap on paying back excess advance credits when you file — so estimate your MAGI carefully and leave a margin below the line.
You can use the subsidy to buy any metal tier plan, not just silver. Many early retirees use the benchmark silver plan's subsidy to buy a bronze plan (lower monthly premium, higher deductible) and pay near-zero in monthly premiums if they're generally healthy — keeping cash in the portfolio and only accessing the deductible if something significant happens.
What Counts as MAGI for ACA Subsidies?
ACA MAGI is similar to regular AGI but includes a few adjustments. Critically for early retirees, not all income sources count the same way:
- Counts as MAGI: traditional IRA/401k withdrawals, wages, self-employment income, taxable interest and dividends, capital gains, rental income, alimony (pre-2019 divorces)
- Does NOT count as MAGI: qualified Roth IRA/401k withdrawals (and Roth IRA contributions withdrawn), HSA distributions for qualified medical expenses, life insurance proceeds, qualified scholarships
- Counts even though it is untaxed: all Social Security benefits (the non-taxable part is added back) and tax-exempt municipal bond interest
The implication is profound: an early retiree living on $60,000 annually might pay $60,000 in expenses but report only $35,000 in MAGI if $25,000 comes from Roth withdrawals. For a couple, that drop takes their expected benchmark-plan contribution from about $5,680 to about $1,730 a year under the 2026 table — roughly $3,950 more in credit every year, or close to $40,000 over a 10-year bridge to Medicare. The stakes are far larger near the cliff: at $84,600 of MAGI a couple still gets the credit, while at $90,000 they get nothing.
The Roth Conversion Strategy for Early Retirees
The most powerful ACA subsidy strategy is executing Roth conversions during the early retirement years before starting Social Security and before MAGI gets locked in by RMDs. The logic:
In the first 2–5 years of early retirement, income is often at its lowest point. No wages, no Social Security yet, minimal required distributions. This is the perfect window to convert traditional IRA funds to Roth at the lowest possible tax rate — filling up the 12% or 22% bracket while keeping MAGI in a subsidy-qualifying range.
Yes, the conversion itself counts as MAGI (and might temporarily reduce your subsidy in conversion years). But future Roth withdrawals are subsidy-free income. A $500,000 traditional IRA converted over 5–7 years creates a $500,000 Roth pool that can generate $70,000+/year in retirement income with zero MAGI impact — maximum ACA subsidies, potentially for life.
This requires careful modeling — the tax cost of conversion must be weighed against the subsidy benefit of lower future MAGI. A tax professional who specializes in early retirement planning can calculate the exact breakeven. For most early retirees, the answer is: convert as much as you can while staying below the 22% bracket.
What Medicare Costs at 65 — And Why It's Not Free
Medicare is often described as "free healthcare" by people who haven't looked at the actual costs. It is not free. Here's what to expect at age 65 in 2026:
- Part A (hospital): Free for most enrollees (those with 40+ quarters of work credits). Provides inpatient hospital, skilled nursing, and hospice coverage.
- Part B (medical): $202.90/month standard premium in 2026. Covers outpatient care, preventive services, durable medical equipment, and most doctors' visits. Higher-income earners pay IRMAA surcharges (a total premium of up to $689.90/month in 2026 for the highest bracket).
- Part D (prescription drugs): CMS projects the average stand-alone plan premium at $34.50/month in 2026. Varies by plan, formulary, and medications needed.
- Medicare Supplement / Medigap: Optional private insurance that covers Medicare's cost-sharing (deductibles, co-insurance). Plan G is the most popular and covers nearly all gaps. Average premium at age 65: $150–$250/month depending on state and health history.
Total for a 65-year-old with Part B + Part D + Medigap Plan G: approximately $390–$490/month per person. For a couple: $775–$975/month. This is substantially lower than the unsubsidized ACA bridge cost — but not trivial.
Medicare Enrollment Timing: Don't Miss It
Medicare enrollment has strict timing rules, and missing them causes permanent premium increases. The Initial Enrollment Period (IEP) runs from 3 months before your 65th birthday month through 3 months after it — a 7-month window total. Enroll during this window and coverage begins on time with no penalties.
If you delay Part B enrollment without qualifying alternative coverage (employer plan, COBRA does not count as qualifying coverage for Medicare delay purposes), you face a Permanent Late Enrollment Penalty: 10% added to the Part B premium for each 12-month period of delay. On the 2026 base premium of $202.90, a 2-year delay creates a $40.58/month surcharge — every month, for life, and it rises as the standard premium rises.
Part D has a similar late penalty: 1% of the national base beneficiary premium per month of delay, also permanent. If you don't need prescription coverage immediately, research whether delaying Part D is appropriate for your situation — or enroll in the lowest-cost Part D plan available to avoid the penalty.
Building the Complete Bridge Plan
The most important thing about healthcare in early retirement is to plan it explicitly — not as a line item that "we'll figure out when we get there," but as a number with a strategy behind it. The basic framework:
- Estimate the full unsubsidized cost using current premium data for your age, location, and family size. Use the healthcare calculator as a starting point.
- Model your MAGI under different income scenarios — what if you use Roth withdrawals instead of IRA withdrawals? What if you keep part-time income below $30,000?
- Calculate the subsidy at each MAGI level and the net premium owed.
- Design your income strategy to optimize the subsidy over the bridge period, while also managing taxes, Social Security timing, and portfolio longevity.
- Budget the total bridge cost as a discrete expense category in your retirement plan — not buried in a generic "expenses" line.
For income strategy, the 72(t) SEPP calculator shows how to access IRA funds before 59½ penalty-free to cover healthcare costs. And the part-time work calculator shows how part-time income — especially if it includes employer-sponsored healthcare coverage — can dramatically change the picture.
