Retirement Healthcare Before Medicare: How to Bridge the Gap From 55 to 65

If you retire before 65, you have three main ways to cover the health insurance gap until Medicare starts: COBRA (continuing your old employer plan, usually for 18 months), an ACA Marketplace plan, or a spouse’s employer coverage if they’re still working. Costs vary enormously, a Marketplace plan can range from a few hundred dollars a month with subsidies to well over $1,500 without them, depending on your income.

Option 1: COBRA

COBRA lets you keep your exact same employer health plan after leaving your job, for up to 18 months in most cases. The tradeoff is cost: you now pay the full premium your employer was previously subsidizing, plus a 2% administrative fee, which commonly runs $800 to $1,500 or more per month depending on your plan and family size. The advantage is continuity, same doctors, same coverage, no new deductible to meet mid-year in some cases, which matters if you’re mid-treatment for something or simply want zero disruption.

Option 2: ACA Marketplace Plans

Marketplace plans, available through HealthCare.gov, can be dramatically cheaper than COBRA if your income qualifies for premium tax credits. The catch for 2026: enhanced subsidies that had lowered premiums since 2021 expired at the end of 2025 and were not renewed, which means the older “subsidy cliff” at 400% of the federal poverty level is back. Below that income threshold, credits can bring a plan down to a few hundred dollars a month. Above it, roughly $62,600 for a single early retiree in 2026, you pay full price, which can exceed $1,500 a month in some markets for someone in their early 60s.

This makes your reported income in early retirement genuinely strategic. If you’re relying heavily on taxable withdrawals that count as income, managing how much you withdraw and from which accounts can directly affect your health insurance subsidy eligibility, not just your tax bill.

Option 3: A Spouse’s Employer Plan

If your spouse or partner is still working and has access to employer coverage, joining as a dependent is frequently the cheapest and simplest option. Losing your own coverage counts as a qualifying life event, giving you a special enrollment window to join their plan outside the normal open enrollment period. This isn’t available to everyone, but if it is, it’s worth comparing seriously against COBRA and Marketplace options before assuming either of those is your only path.

Should You Use an HSA to Cover This Gap?

If you have a Health Savings Account from earlier working years, it can be a genuinely useful tool here. HSA funds can pay for qualified medical expenses, and in many cases COBRA premiums specifically, tax-free at any age, which is a meaningful advantage over paying those premiums with regular after-tax retirement withdrawals. See our HSA triple tax advantage guide for how this works and why building HSA savings before retiring can pay off specifically during this pre-Medicare gap.

How Should You Plan for This Cost in Your Retirement Number?

Health insurance before Medicare is often underestimated in early retirement planning. If you’re retiring at 60 rather than 65, that’s potentially 5 years of premiums, easily $10,000 to $20,000+ per year depending on your situation, that need to be built into your retirement number on top of ordinary living expenses. This is a common gap in FIRE-style planning specifically, since early retirees face more pre-Medicare years than someone retiring at a traditional age.

• Budget explicitly for this gap rather than assuming it’s a minor add-on to your normal expenses.
• Compare all three main options (COBRA, Marketplace, spouse’s plan) rather than defaulting to whichever one you think of first.
• Factor subsidy eligibility into your withdrawal strategy, since managing your reported income can directly reduce your health insurance costs if you’re near the subsidy cliff.
• Review your full expense picture alongside other costs retirees often overlook, see our retiree expenses guide for other areas worth reviewing.

FAQ

How do I get health insurance if I retire before 65?

Your main options are COBRA (continuing your old employer plan, typically up to 18 months), an ACA Marketplace plan, or joining a working spouse’s employer plan if available.

How much does COBRA cost after retiring?

You pay the full premium plus a 2% administrative fee, commonly $800 to $1,500 or more a month, since your employer is no longer subsidizing any part of it.

Can I get subsidies for Marketplace insurance in early retirement?

Possibly, if your income falls under 400% of the federal poverty level. Above that threshold, the subsidy cliff returned for 2026, meaning you’d pay full price.

Can I use my HSA to pay for health insurance before Medicare?

Often yes, HSA funds can generally cover COBRA premiums tax-free, which can meaningfully reduce the cost of bridging this gap compared to paying with regular retirement withdrawals.

Bottom Line

Retiring before 65 means budgeting seriously for health insurance until Medicare starts, since COBRA and full-price Marketplace coverage can both run well over $1,000 a month. Compare all three main options, and consider how your withdrawal strategy affects your Marketplace subsidy eligibility before assuming early retirement is affordable without this cost built in.

A quick note: health insurance costs and subsidy rules can change from year to year and vary by state and household income. Check HealthCare.gov directly for your current options, and consider talking to a financial planner about how this gap fits into your broader retirement timeline.
