Most people spend years planning for retirement savings, Social Security timing, and investment strategy. Far fewer spend equivalent time on a cost that can single-handedly derail an early retirement budget: health insurance.
Medicare eligibility begins at 65. If you retire at 60 — or 58, or 62 — you face a gap that can span years during which you are entirely responsible for your own medical coverage. For a healthy 62-year-old, individual premiums alone can run $600 to $1,200 per month or more before factoring in deductibles, copays, and out-of-pocket maximums.
Over a three-year bridge to Medicare, that's a potential six-figure expense — one that many retirement income projections either underestimate or omit entirely. Here's how to evaluate every option and build this cost in accurately before it surprises you after.
Why the Healthcare Gap Is Bigger Than Most Retirees Expect
When you're employed, your employer typically covers 70–80% of your health insurance premium. The remainder is deducted from your paycheck pre-tax, making the visible cost feel modest. When you retire before 65, that employer subsidy disappears — and you pay the full premium with after-tax dollars.
The gap compounds in other ways: healthcare costs inflate above general inflation, out-of-pocket expenses are variable and underestimated, dental and vision (largely not covered by Medicare) add separate costs, and the risk of a health event during the bridge adds exposure that fixed-premium planning doesn't capture.
Healthcare is not a line item to estimate casually for early retirees. It warrants the same deliberate analysis as Social Security timing or portfolio withdrawal strategy.
Option 1: COBRA Continuation Coverage
COBRA gives you the right to continue your employer's group coverage for up to 18 months after leaving. Some qualifying events extend eligibility further.
Advantage: Same plan, same network, same providers — no medical underwriting. If continuity of care matters, it's real value.
Disadvantage: You pay the full premium — your share plus the employer's share — plus up to a 2% administrative fee. Total monthly COBRA premiums for individual coverage commonly run $700 to $1,500 or more.
COBRA is typically most useful when the gap to Medicare is 12–18 months or when continuity with specific providers is a priority. For someone retiring at 60 with five years until Medicare, it is almost never a long-term solution. Important: You have 60 days from losing employer coverage to elect COBRA. The window does not extend.
Option 2: ACA Marketplace Plans
The ACA marketplace offers individual plans in Bronze, Silver, Gold, and Platinum tiers with income-based premium tax credits that can significantly reduce costs for qualifying individuals.
Income management opportunity: In the years before Social Security and RMDs begin, a retiree living on modest portfolio withdrawals may have relatively low reportable income — potentially qualifying for meaningful subsidies. Deliberate management of taxable income to maximize ACA subsidy eligibility is one of the underappreciated financial planning opportunities in the pre-Medicare window.
The trade-off: Managing income for subsidy eligibility must be balanced against Roth conversion opportunities, tax bracket management, and large one-time income events. These interact in ways that require coordinated planning.
Network matters: Plan quality varies significantly by region. Whether your current doctors and specialists participate in the plan's network is as important as premium cost. Review provider directories before selecting a plan.
Enrollment timing: Retiring and losing employer coverage is a qualifying life event — you have 60 days to enroll in a marketplace plan outside of annual Open Enrollment.
Option 3: Coverage Through a Spouse's Employer
If your spouse is still working with employer-sponsored coverage, joining their plan is typically the most cost-effective option — employer plans carry the best premium-to-coverage ratio because the employer absorbs a substantial share of the cost.
Losing your own employer coverage is a qualifying life event, typically giving you 30 days (check your specific plan) to be added to a spouse's plan outside of their open enrollment window. Evaluate the premium impact, coverage adequacy for your situation, and duration if your spouse is also approaching retirement.
Option 4: Short-Term Health Plans
Short-term plans offer substantially lower premiums but can exclude pre-existing conditions, apply benefit caps, and limit covered services. They are not regulated as comprehensive insurance. Appropriate only for individuals in excellent health facing a very short coverage gap who understand the limitations. Several states restrict or prohibit short-term plans — verify availability before purchasing.
Building the Healthcare Bridge into Your Retirement Plan
A practical framework for most early retirees:
Step 1: Determine your gap
How many months or years between retirement and Medicare? The longer the gap, the more important it is to find a sustainable solution rather than a temporary patch.
Step 2: Assess your income structure
What will your taxable income be in each year of the gap? Low-income years may qualify for significant ACA subsidies. Higher-income years (Roth conversions, business sale proceeds) may make COBRA comparatively competitive.
Step 3: Evaluate your health situation
Ongoing conditions, prescription needs, and specialist relationships all affect which option provides the best value. Premium is only one dimension — network access and out-of-pocket exposure matter equally.
Step 4: Price every option
Get actual quotes for marketplace plans in your area at your projected income levels. Get your COBRA cost from HR before you retire. Check your spouse's employer plan. Build the real numbers into your retirement income projection.
Step 5: Plan for IRMAA when Medicare arrives
The income decisions you make during the bridge period affect Medicare premiums in the first year or two of eligibility through the IRMAA two-year lookback. Coordinate healthcare cost planning with Medicare premium planning — they are not separate problems.
The Cost That Makes or Breaks Early Retirement
For many people retiring between 60 and 64, the healthcare bridge is the single largest variable expense in their retirement plan — one that determines whether an early retirement is financially viable or requires more runway. Getting the analysis right before you retire, with actual costs at your projected income levels, is the difference between a plan built on accurate numbers and one built on assumptions that unravel in the first year.
