Summary: Retiring before 65 means bridging to Medicare, and COBRA's 18 months rarely covers the whole gap. Early retirees have four main options: COBRA, marketplace plans with subsidies, employer retiree plans, and health care sharing ministries. This guide prices each for the pre-Medicare bridge and explains how to sequence them.
The early retiree's health insurance problem is a duration problem. COBRA lasts 18 months; the gap to Medicare at 65 can be years. And COBRA's $793 to $2,294 a month is painful on a fixed retirement income. The good news is that early retirees have more options than laid-off workers, including some of the best subsidy treatment in the marketplace.
This guide maps the bridge options in the order most retirees should evaluate them.
Early retirees with health savings accounts have an extra lever: HSA funds pay COBRA premiums tax-free, which effectively discounts the premium by your marginal tax rate. Paying $793 a month from an HSA at a 22 percent bracket costs about $619 in pre-tax-equivalent dollars. This does not make COBRA cheap, but it narrows the gap with marketplace options.
Taxable brokerage accounts are the other choreography piece: living on basis and long-term gains you control lets you tune your modified adjusted gross income for subsidy purposes in a way that salary never allowed. The retirees who pay least for health insurance are the ones who plan withdrawals and conversions as a single system, years ahead.
COBRA is the default first step for most early retirees because it is immediate, familiar, and retroactive. If you retire at 63 and a half, 18 months of COBRA carries you to 65 and Medicare. The math works when the remaining gap fits inside 18 months and the premium fits the budget.
COBRA's weakness for retirees is price on a fixed income and the hard stop at 18 months. If you retire at 60, COBRA covers less than half the gap. Use it as the opening bridge while you arrange the longer-term option, not as the whole plan.
Early retirees are often shocked, pleasantly, by marketplace subsidies. Premium tax credits are based on income, and a retiree living on modest Roth conversions or taxable account draws can show low income and qualify for substantial subsidies, sometimes bringing a silver plan under $200 a month.
Manage your income deliberately: Roth conversions, capital gains harvesting, and part-time work all count toward the subsidy calculation. The difference between showing $30,000 and $60,000 of income can be thousands a year in premium credits. This is tax planning and health insurance planning in one decision.
Some employers offer retiree health plans that bridge to 65. These vary enormously: some are subsidized generously, others are COBRA-priced with a different name. Evaluate them exactly like COBRA: get the premium, the network, and the duration in writing.
Retiree plans sometimes include a Medicare supplement component for after 65, which adds long-term value beyond the bridge. If your employer offers one, price the whole package before dismissing it.
Sharing ministries are not insurance: members share costs voluntarily, there is no contractual guarantee of payment, and they are exempt from ACA consumer protections. Monthly shares are often lower than unsubsidized premiums, which attracts healthy early retirees.
The risks are real: no guaranteed coverage, exclusions for pre-existing conditions, and no recourse if the ministry does not pay. For a retiree with any significant health history, the savings are not worth the risk. Treat sharing ministries as a last resort, not a clever hack.
The common winning sequence: COBRA for the first months (continuity, retroactive safety net), then marketplace coverage with managed income for subsidies through 64, then Medicare at 65. Time the COBRA-to-marketplace switch for open enrollment or the end of COBRA, which triggers its own special enrollment.
One timing trap: do not let COBRA expire without a landing spot. The end of COBRA triggers a special enrollment period, but you must act within 60 days. Calendar it a year ahead.
At 65, the bridge ends and Medicare begins, with its own enrollment choreography: the 7-month initial enrollment period, Part D decisions, and Medigap versus Advantage choices. Start learning the system at 64, not at 65.
A final note on income management: your income at 63 determines your Medicare Part B and D premiums at 65 through IRMAA. The Roth conversions that optimized your marketplace subsidies at 62 can raise your Medicare premiums at 65. Plan the whole arc, not each year in isolation.
Build a simple year-by-year map from retirement to age 65: coverage source, expected premium, and planned income each year. The map fits on one page and turns five years of improvisation into one planned sequence. Review the map every open enrollment; a single changed assumption, like a part-time job offer with benefits, can rewrite the whole bridge. The best time to build the map is the month you retire, while HR is still answering your calls and every document is at hand.
Usually a subsidized marketplace plan, with managed income keeping premium tax credits high. COBRA is simpler but rarely cheapest for multi-year gaps.
Only if the gap is 18 months or less. Retiring at 60 leaves years uncovered; sequence COBRA into marketplace coverage.
They are cheaper but are not insurance: no guaranteed payment, no ACA protections, pre-existing exclusions. A last resort, not a plan.
Premium tax credits scale with income. Managing Roth conversions and withdrawals to keep income in subsidy range can save thousands a year.
