Almost every retirement plan we see has the same soft spot. The money side is worked out to the dollar — the withdrawal order, the pension election, the Social Security claiming age — and then health coverage gets a line that says "COBRA, then figure it out." That works for eighteen months. Retiring at 60 leaves five years to cover. Retiring at 55 leaves ten.

The good news is that this is an arithmetic problem, not a luck problem, and the arithmetic has a specific shape: the premium you are quoted rises with age, but the help you can get rises with it too, and which of those two forces wins is decided almost entirely by a number you have more control over in retirement than you ever did while working. This guide lays out the actual 2026 figures at 55, 60 and 64, the COBRA comparison, and the income line everything hinges on.

First, size the bridge

Before any premium matters, count the months. Medicare eligibility begins at 65 for almost everyone, so the gap is fixed by your retirement date and nothing else.

That last row is why advice written for 63-year-olds is useless to a 55-year-old. If you leave work at 63½, COBRA genuinely is the whole answer and you can stop reading. Below that, COBRA is a bridge to another bridge, and the second one is the one worth planning.

What the individual market actually charges at 55, 60 and 64

These are 2026 statewide median monthly premiums for a single adult, before any premium tax credit. "Bronze" is the lowest-cost bronze plan in a county; "benchmark silver" is the second-lowest-cost silver plan, which is the figure every subsidy calculation is built on.

Source: CMS QHP Landscape, Individual Medical, plan year 2026 (data.healthcare.gov), statewide medians of per-county values, non-tobacco, before any tax credit. Data current as of August 4, 2026; downloaded and re-verified September 14, 2026. The federal file covers the 30 states using HealthCare.gov. Method note: the CMS file publishes ages 21, 27, 30, 40, 50 and 60. The 55 and 64 columns are the same county's age-21 premium multiplied by the federal default standard age curve (2.230 at 55, 3.000 at 64), the schedule nearly every state uses under 45 CFR 147.102. We checked the method against the file's own numbers first: it reproduces the published age-50 and age-60 premiums to the cent in 29 of the 30 states. Utah is the exception — it uses a state-specific curve that reaches the federal 3:1 maximum by age 60, so a Utah 64-year-old is charged the same as a 60-year-old, and Utah is left out of the table above for that reason.

Two things stand out. The first is the spread: a 60-year-old in New Hampshire and a 60-year-old in Wyoming are buying the same legally-defined product at roughly two and a half times the difference in price. Where you retire to is a coverage decision, not only a lifestyle one, and it is worth running before you sign on a house.

The second is that "+35%" repeating down the last column. That is not a coincidence and it is not inflation. Federal law caps what an insurer may charge a 64-year-old at three times what it charges a 21-year-old, and the standard curve spends most of that allowance well before 55. From 55 to 64 the rate climbs about 35 percent and then stops cold — there is no further age increase after 64, and nothing about turning 60 triggers a jump. If you have been told to expect premiums to "double in your sixties," that is not how the rating rules work.

The part that surprises people: with a credit, aging can get cheaper

A premium tax credit is not a discount percentage. It is a subtraction. The marketplace works out what your household is expected to contribute toward the benchmark silver plan — a set percentage of your income — and the credit is whatever is left over after that. Your income sets your contribution; your age sets the benchmark. So when age pushes the benchmark up, the credit absorbs the increase.

Here is the same person, in Ohio, with $55,000 of modified adjusted gross income, at three ages.

Illustration, not a quote. Ohio statewide median premiums from the CMS plan-year-2026 landscape file (checked September 14, 2026), single-person household, $55,000 MAGI = 351% of the 2025 federal poverty guideline of $15,650 that governs 2026 eligibility, applicable contribution 9.96% under IRS Rev. Proc. 2025-25. Your county, plan and household will differ.

Subsidized, the net cost of a bronze plan falls by about a quarter between 55 and 64. Unsubsidized, it rises by a third. Same person, same state, same plan — the entire direction of the trend is set by whether a credit is in play. That is the single most consequential fact in this guide, and it is why the next section is about income rather than insurance.

The 2026 income line, and the cliff that came back

The enhanced premium tax credits created in 2021 expired on December 31, 2025, and Congress has not extended them for 2026. What returned with their expiry is the original hard cutoff at 400 percent of the federal poverty level: one dollar of income above the line and the credit is not reduced, it is gone.

2025 HHS poverty guidelines for the 48 contiguous states and DC (90 FR 5917, January 17, 2025), which set eligibility for 2026 coverage; Alaska and Hawaii use higher figures. Checked September 14, 2026.

For a household in its fifties or sixties, that cliff is the most expensive edge in the tax code. Two worked examples, both using the 2026 numbers above:

• Single, 60, Ohio. At $62,600 of MAGI — exactly 400 percent — the expected contribution is $520 a month and the credit is about $618 a month, or $7,413 over the year. At $63,000, the credit is $0. Four hundred dollars of extra income costs more than seven thousand.
• Couple, both 60, Florida. At $84,000 of MAGI the benchmark for two 60-year-olds is $2,969 a month, the expected contribution is $697, and the credit is about $2,272 a month — roughly $27,300 for the year, enough to bring the lowest-cost bronze plan to $0 in premium. At $85,000, the same couple pays the full $2,187 a month for that bronze plan. One thousand dollars of income, about twenty-six thousand dollars of consequence.

We wrote a full walkthrough of the subsidy cliff if you want the mechanics, and a separate guide on what to do when your income puts you above the line for good and permanent reasons.

One more 2026 change matters specifically to retirees with lumpy income. Public Law 119-21, enacted July 4, 2025, removed the cap on repaying excess advance credits beginning with the 2026 tax year. Before, a household that underestimated its income owed back only a limited amount. Now the whole overpayment comes back at filing. A Roth conversion done in December, an unplanned capital gain, a mutual fund distribution — any of these can retroactively push you over the line for the whole year, and the bill arrives the following April. Confirm the current rule and your own projection with your tax professional before you act on it.

COBRA: 18 months, and the one case where it genuinely wins

COBRA lets you keep your employer's plan after you leave, generally for 18 months, and you pay the entire premium — the employer's share as well as yours — plus an administrative fee of up to 2 percent. People react to that number badly, because they have only ever seen the payroll-deduction half of it. But the full group premium is a blended rate across the employer's whole workforce. It is not priced on your age. That is the thing worth understanding before you decline it.

Average annual premiums for employer-sponsored coverage from the KFF 2025 Employer Health Benefits Survey; COBRA figures are those premiums at the statutory 102% maximum. Your own employer's rate may be well above or below the national average — ask HR for the COBRA election notice figure rather than using this one.

Set that $793 against the table further up. A 60-year-old in Florida pays $1,093 a month for the cheapest bronze plan at full price; in Arizona, $1,233. At 64, more. COBRA at an average group rate beats both — and it keeps the doctors, the deductible you have already partly met, and the drug list you already know. For a household above the subsidy line, COBRA is frequently the better deal for its full 18 months, and treating it as the expensive option is a mistake.

The reverse is just as firm. Enrolling in COBRA is enrollment in an employer-sponsored plan, so you cannot claim a premium tax credit for any month you are covered by it. The subsidized Ohio 60-year-old above pays $217 a month; COBRA would cost that person $793 and forfeit $8,170 of credit over the year. When a credit is available, it is not close.

Three practical notes. Losing job-based coverage opens a special enrollment period on the marketplace — generally 60 days — so you do not have to wait for open enrollment to choose, but the window is short and it does not reopen. You may take COBRA now and move to a marketplace plan later, at open enrollment or when COBRA is exhausted, though voluntarily dropping COBRA early does not by itself create a special enrollment period. And deductibles usually restart when you change plans, so mid-year switching costs more than the premium difference suggests. Our COBRA alternatives walkthrough runs the comparison in more detail.

Income is the lever, and retirement is when you finally get to pull it

While you were working, your MAGI was whatever payroll said it was. Retired, it is largely a function of which account you draw from, and that is a choice. This is where an early retiree's health coverage is actually decided.

• Where the withdrawal comes from changes the count. Taking $60,000 from a traditional IRA is $60,000 of MAGI. Taking $60,000 from a taxable brokerage account is only the realized gain portion — the return of your own basis is not income. Qualified Roth distributions are not MAGI at all. Same spending, very different subsidy outcome.
• Roth conversions cut both ways. Converting during the bridge years fills up low tax brackets cheaply, and it is often exactly the right move — but every converted dollar counts toward the 400 percent line. Some households convert aggressively from 65 to 73 instead, once Medicare has taken the subsidy question off the table.
• Health savings account contributions reduce MAGI if you are covered by a qualifying high-deductible plan and not yet enrolled in Medicare. That is one of the few levers that lowers the number and builds an asset at the same time.
• Social Security timing interacts with all of it. Claiming early adds taxable benefits to the count in precisely the years you may most want the count low.
• Below about 138 percent of poverty, the answer changes entirely — in states that expanded Medicaid, low-income adults under 65 are generally eligible for Medicaid rather than a subsidized marketplace plan, and in states that did not expand there is a coverage gap below 100 percent with no credit available. Check your state's rules; this is not a place to guess.

None of this is tax advice, and the interactions are genuinely intricate. The right sequence is to have your tax professional project the MAGI and then price coverage against it — not the other way round.

Where private underwritten plans fit, and where they don't

Outside the marketplace there are medically underwritten plans that may quote well below an unsubsidized ACA premium for a healthy applicant. For some early retirees above the subsidy line and in good health, they are worth pricing. The conditions attached are real and you should hear them plainly:

• They are not guaranteed issue. You answer health questions, and the carrier can decline you or issue with exclusions.
• They may limit or exclude pre-existing conditions. If you are carrying anything — a joint that will need replacing, a medication you depend on, a condition under monitoring — this is usually the wrong direction.
• Short-term plans in particular are not ACA coverage. The 2024 federal rule capping them at four months has not been rescinded, though federal enforcement has been de-prioritized since August 2025 and states set their own limits — some permit up to 36 months, others ban them outright.

Honest summary: if you qualify for a premium tax credit, marketplace coverage is very likely your answer and the private route is a distraction. If you are firmly above the line, healthy, and facing four or five years of full-price premiums, it deserves a serious quote alongside the marketplace and COBRA rather than instead of them.

55 and 60 are not the same problem

Retiring at 55 means a decade of coverage and roughly two presidential terms of possible rule changes. The enhanced credits that existed from 2021 through 2025 are gone; whether something replaces them is a live question. Plan for the rules as they are, keep the plan reviewable each fall, and be wary of any strategy that only works if a particular law passes. Ten years is also long enough that a move across a state line is a genuine lever — the spread in the table above is not small.

Retiring at 60 is a tighter, more solvable problem: 18 months of COBRA and then about three and a half years to cover. Many households in this position run COBRA to its end and then take a subsidized marketplace plan for the remainder, which also means only one plan change before Medicare. Others decline COBRA immediately because the credit makes the marketplace cheaper from day one. Both are defensible. Which one is right depends on the credit you qualify for and on whether you are mid-treatment with a deductible already partly met.

If your retirement is in a specific state, our per-state early-retiree guides carry local carrier counts and marketplace details — Florida, Ohio and Texas among them.

The handoff at 65

The last mile trips more people than the first. Medicare's Initial Enrollment Period runs seven months — three months before the month you turn 65, the birthday month, and three months after — and Medicare coverage always begins on the first of a month. Your marketplace plan does not end on its own, and your premium tax credit stops once Medicare Part A begins, so a plan left running quietly creates a repayment. Individual marketplace coverage is also generally not creditable coverage for Part B purposes, which means delaying Part B because "I already have insurance" can attach a lifetime late-enrollment penalty. Enroll during the window, then cancel the marketplace plan effective the day before Medicare starts. The rules and enrollment itself are at medicare.gov or 1-800-MEDICARE.

What to do this month

• Count the months. Retirement date to 65, minus 18 if COBRA is available. That number, not the premium, tells you which plan you are making.
• Get the real COBRA figure from HR or the election notice. The national average is a starting point, not your number.
• Have your tax professional project next year's MAGI — including any conversion, gain or distribution you are contemplating — and see where it sits against the line for your household size.
• Price the marketplace at that MAGI, not at your final working year's income. The two are rarely close.
• Note the dates. Open enrollment for 2027 coverage runs November 1, 2026 through January 15, 2027 on HealthCare.gov, with a December 15 deadline for a January 1 start; state-run marketplaces set their own closing dates. Leaving a job opens a special enrollment period of its own — see the 2027 dates, state by state.
