Medicare starts at 65. If you retire at 45 or 50, you have 15 to 20 years of healthcare costs to cover privately. It's the most underestimated expense in early retirement planning and the single biggest cost that breaks FIRE plans. Here's what it actually costs and how to handle it.

A 50-year-old couple averages $22,000-$28,000/year in health premiums before Medicare, plus out-of-pocket. Over 20 years that's a $500k-$700k liability. ACA subsidies are income-based, not asset-based, so controlling reportable income (Roth withdrawals don't count) can dramatically reduce this. HSAs are your best long-term healthcare funding source. Long-term care is a separate, larger, ignored problem.
Average annual healthcare cost for a 50-year-old couple before Medicare: approximately $22,000-$28,000/year in premiums alone 🔍 verify×DON'T TRUST, VERIFYClaim: Pre-Medicare couple premiums run $22k-$28k/year.Verify at: KFF health cost research ↗State-dependent. ACA subsidies reduce substantially for qualifying incomes.. Plus out-of-pocket costs. That's a $500,000-$700,000 liability over a 20-year pre-Medicare period at current costs, before inflation.
Most retirement calculators ignore this or dramatically underestimate it. If you're doing FIRE math, this line alone can add 5-10 years to your required portfolio.
The Affordable Care Act marketplace is the primary option for early retirees. The key insight most people miss: ACA subsidies are income-based, not asset-based. A person with $2M in assets but $40,000 in reportable income qualifies for substantial subsidies.
If you control your reportable income in retirement, you can qualify for subsidies while sitting on significant wealth:
The strategy: live primarily off Roth withdrawals in early retirement. Report low income. Get ACA subsidies. This is why the Roth conversion ladder paired with ACA is so powerful. 400% FPL for a single person is about $60,000 in 2026 🔍 verify×DON'T TRUST, VERIFYClaim: 400% FPL for single ~$60k in 2026.Verify at: HHS poverty guidelines ↗Updated annually.

If you contribute to an HSA during working years and save every medical receipt, you can withdraw HSA funds tax-free at any age for those past medical expenses. There's no time limit.
An HSA with 10-15 years of invested growth becomes a significant healthcare funding source in early retirement. Full strategy: HSA Deep Dive.
An alternative some early retirees consider: lower monthly cost than traditional insurance, but not insurance. Members share costs voluntarily. Significant limitations and exclusions apply. Not HIPAA protected. Not guaranteed coverage.
Works for healthy people with low healthcare usage. High risk for anyone with pre-existing conditions. Listed as an option, not a recommendation.
The cost most people don't plan for 🔍 verify×DON'T TRUST, VERIFYClaim: Nursing home ~$8-10k/month, home care ~$5-6k/month, average duration 2.5 years.Verify at: Genworth Cost of Care ↗Rates vary by state and facility type. Genworth publishes annual survey.:
Options: self-insure (needs significant assets), long-term care insurance (expensive, buy in your 50s before premiums spike), hybrid life insurance + LTC rider, or Medicaid (requires spending down assets with a 5-year lookback period).
Bitcoin consideration: if your estate plan is hold Bitcoin for stepped-up basis, long-term care costs could force a sale before death. Plan accordingly.
At 65, you transition to Medicare:
IRMAA trap: high-income retirees (including high Roth conversion years) pay Medicare surcharges. Realizing large Bitcoin gains at 65+ can cost you both capital gains tax and years of IRMAA surcharges. Another reason to realize gains in low-income years before Medicare starts.
