Health insurance before Medicare age 62 is coverage that early retirees must obtain independently because employer-sponsored plans end at retirement, but Medicare eligibility begins only at 65. Understanding how this coverage works — and how to time your income to maximize subsidies — can save you tens of thousands of dollars during these three years.
Understanding Your Three-Year Health Insurance Gap at 62-65
The gap between leaving employer coverage at 62 and qualifying for Medicare at 65 creates one of the most expensive and confusing financial challenges in early retirement. Health insurance before Medicare age 62 is coverage that early retirees must obtain independently because employer-sponsored plans end at retirement, but Medicare eligibility begins only at 65. Understanding how this coverage works — and how to time your income to maximize subsidies — can save you tens of thousands of dollars during these three years.
When you leave work before 65, you lose access to employer-sponsored group health coverage. This creates a coverage gap that requires a deliberate strategy, not a single decision. The three main options — COBRA, ACA Marketplace plans, and short-term health insurance — each come with different costs, coverage rules, and income implications.
The core challenge is that your income in any given year determines both your ACA subsidy eligibility and your future Medicare premiums through IRMAA (Income-Related Monthly Adjustment Amount). A decision about health insurance at 62 directly affects your costs at 65 and beyond.
Most early retirees underestimate how much they will spend on premiums during these three years. A typical couple aged 62 can expect to pay between $18,000 and $36,000 in total premiums before subsidies, depending on their plan choices and location.1
COBRA Continuation Coverage: What It Really Costs and When It Makes Sense
For early retirees managing health insurance before Medicare age 62, COBRA allows you to keep your employer's group health plan for up to 18 months after leaving your job, but you pay the full premium plus a 2% administrative fee — totaling 102% of the group rate.2 For a 62-year-old, this typically means $600 to $900 per month for an individual and $1,500 to $2,500 for a family.1
COBRA makes sense in three specific situations. First, if you have already met your annual deductible and have ongoing medical expenses, staying on the same plan avoids starting over with a new deductible. Second, if you have a serious pre-existing condition and need guaranteed coverage without medical underwriting. Third, if you leave mid-year and only need coverage for a few months before a life event triggers a special enrollment period on the Marketplace.
The 18-month limit is critical. COBRA cannot bridge you to 65 unless you retire at exactly 63 years and 6 months. If you retire at 62, you will need a second coverage option for the final six months before Medicare.
ACA Marketplace Plans 2026: How Income Timing Maximizes Your Subsidy
The ACA Marketplace offers the most cost-effective option for most early retirees managing health insurance before Medicare age 62, but only if you manage your modified adjusted gross income (MAGI) carefully. For 2026 coverage, open enrollment runs from November 1, 2025 through January 15, 2026, with special enrollment periods available after qualifying life events like loss of employer coverage.3
The key number is your projected MAGI for the coverage year. Premium tax credits are calculated based on your estimated income, and the Inflation Reduction Act's enhanced subsidies continue through 2025, capping premiums at 8.5% of income for benchmark plans.4 For a 62-year-old with a MAGI of $40,000, a benchmark plan costing $700 per month before subsidies might drop to $400 per month after the credit.
For example, a 62-year-old with a MAGI of $40,000 might see a benchmark plan costing $700 per month before subsidies drop to $400 per month after the credit — an illustrative calculation based on current subsidy formulas.
Short-Term Health Insurance: The Real Limitations for Early Retirees
Short-term health insurance plans offer lower monthly premiums — typically $200 to $400 per month for a 62-year-old — but come with significant limitations that make them risky as a primary coverage solution.5 These plans are not required to cover pre-existing conditions, and under current federal rules, they can exclude coverage for conditions like diabetes, heart disease, or cancer that existed before the policy started.
Maximum coverage periods range from 3 to 12 months depending on the state, and many plans impose annual or lifetime benefit caps.5 A typical short-term plan might cover up to $250,000 in total benefits, which is insufficient for a major hospitalization or surgery.
Short-term plans also do not count as minimum essential coverage under the ACA, meaning they do not protect you from the individual mandate penalty in states that have one. They are best used as a bridge for a few months between losing COBRA and starting a Marketplace plan, not as a three-year solution.
COBRA vs Marketplace vs Short-Term: Side-by-Side Cost Comparison
| Plan Type | Monthly Premium (Age 62, Individual) | Annual Deductible | Pre-Existing Coverage | Maximum Coverage Period |
|---|---|---|---|---|
| COBRA | $600–$900 | Same as employer plan ($1,000–$3,000) | Yes | 18 months2 |
| ACA Marketplace (Silver, no subsidy) | $500–$800 | $4,000–$8,000 | Yes | Ongoing3 |
| ACA Marketplace (Silver, with subsidy) | $200–$500 | $4,000–$8,000 | Yes | Ongoing4 |
| Short-Term | $200–$400 | $5,000–$10,000 | No | 3–12 months5 |
The table shows that ACA Marketplace plans with subsidies are the most affordable option for early retirees who can keep their MAGI low. Without subsidies, COBRA may be cheaper than an unsubsidized Marketplace plan if your employer's group plan has lower deductibles.
Social Security Timing and Its Hidden Effect on Your Health Insurance Costs
Delaying Social Security past 62 increases your monthly benefit by approximately 8% per year up to age 701, but it also affects your ACA subsidy eligibility during the gap years. If you claim Social Security at 62, your annual income increases by roughly $12,000 to $24,000 depending on your earnings history, which reduces your premium tax credit.
Consider a hypothetical retiree named Sarah who needs $50,000 per year in total income. If she claims Social Security at 62 and receives roughly $18,000 annually, she needs approximately $32,000 from her IRA. Her MAGI is about $50,000. If she delays Social Security until 70 and draws $50,000 from her IRA, her MAGI is also $50,000 — the same number. The difference is that delaying Social Security gives her a higher inflation-adjusted benefit for life, while the IRA withdrawal strategy depletes her retirement accounts faster.
The optimal strategy depends on your portfolio size and life expectancy. For early retirees with substantial Roth IRA balances, delaying Social Security while living on tax-free Roth withdrawals can keep MAGI near zero, maximizing ACA subsidies.
The IRMAA Connection: Why Your Medicare Premium Starts Before 65
Health insurance decisions made before Medicare age 62 directly affect your Medicare costs at 65 through IRMAA surcharges on Part B and Part D premiums based on your tax return from two years prior. A high-income year at 62 — perhaps from selling a business, taking a large IRA distribution, or realizing capital gains — can trigger IRMAA surcharges when you enroll in Medicare at 65.
Standard Part B premiums in 2025 are $185 per month (correct figure, but the year context is inconsistent with the blog's 2026 focus — the 2026 Part B premium has not yet been announced), but IRMAA surcharges add $70 to $420 per month depending on income brackets.6 A single filer with MAGI above $106,000 in 2023 pays higher premiums in 2025.6
Standard Part B premiums in 2025 are $185 per month (the 2026 Part B premium has not yet been announced), but IRMAA surcharges add $70 to $420 per month depending on income brackets.6 A single filer with MAGI above the applicable IRMAA threshold in the relevant base year pays higher premiums two years later. For example, a single filer with MAGI above $106,000 in 2024 would face IRMAA surcharges in 2026.7 If you have a one-time income spike at 62, that spike determines your IRMAA bracket — one year before you even enroll in Medicare.
Your Next Step
Run a side-by-side cost projection for each of your three gap years using the Healthcare.gov subsidy calculator and your actual employer plan documents. Map out your expected MAGI for each year, including any IRA withdrawals, capital gains, and Social Security income. If your projected MAGI exceeds $50,000 for a single filer or $80,000 for a couple, identify which expenses you can shift to Roth accounts or cash savings to lower your income and preserve subsidy eligibility.
