COBRA vs. a Marketplace Plan After Job Loss: Comparing the Real Monthly Cost
By the Stoia team · September 12, 2026 · 8 min read
After a layoff, COBRA is usually the more expensive premium and a marketplace plan is usually the cheaper one, and the deductible decides which is actually cheaper for you. COBRA keeps the exact plan you had, with the deductible progress you already paid, at the full premium your employer used to share. A marketplace plan restarts the deductible at zero, but its premium is reduced by a tax credit based on the income you now expect for the year. Compare the total for the months you expect to be between jobs, not the premium alone.
The three doors when employer coverage ends
Employer coverage typically ends on the last day of the month you leave, sometimes on the last day worked. Before it does, three doors open, each with its own clock:
- COBRA continues the same group plan, usually for up to 18 months. It applies to employers with 20 or more employees; most states have a continuation law for smaller employers that works similarly for a shorter period.
- A marketplace plan. Losing job-based coverage is a qualifying event that opens a 60-day special enrollment period on HealthCare.gov or your state's exchange. You can also apply up to 60 days before the coverage ends so the new plan starts the day after the old one stops.
- A spouse's or parent's plan. Loss of coverage lets you join a spouse's employer plan outside its normal enrollment season, and an adult under 26 can join a parent's plan. This window is the shortest, usually 30 days.
One more door exists when income falls far enough. Medicaid eligibility in most states looks at current monthly income rather than the annual total, so a household with no income this month may qualify even if the year's total is high; the marketplace application routes you there automatically when it applies. The coverage decision is one item on the 72-hour plan, and it is the one with the hardest deadline.
How COBRA pricing works, and why waiting inside the window is allowed
While you were employed, the premium was split: the employer paid a large share and you paid the rest from your paycheck. COBRA charges you both shares plus an administrative fee of up to 2%. If the employer paid $520 a month and you paid $200, the COBRA premium is the full $720 plus up to about $14 in fees. That jump, not any change in the plan, is why COBRA looks shocking on the notice.
The timing rules are more generous than most people realize. You have 60 days from the later of the date coverage ended or the date the election notice arrived to decide. If you elect, coverage is retroactive to the day the employer plan ended, with no gap, and the first premium is due within 45 days after you elect. So you can sit inside the window with no premium paid, and if nothing happens, never elect. If something does happen, you elect, pay the back premiums, and the claim is covered. Two cautions: providers may ask for payment up front while coverage shows as pending, and pharmacies will charge cash until the election is processed, with reimbursement afterward. If you already have an HSA, its balance can pay COBRA premiums, which is one of the few times premiums are a qualified expense.
How marketplace pricing works after your income drops
Marketplace plans are sold in metal tiers (bronze, silver, gold, platinum) that trade premium against deductible: bronze is the lowest premium and the highest deductible, gold the reverse. The premium tax credit lowers what you pay each month, and its size depends on your expected household income for the calendar year relative to the federal poverty level and on the cost of a benchmark silver plan in your county.
Two details matter after a layoff. First, the credit uses annual income, not this month's. Wages you already earned before the layoff count, severance counts in the year it is paid, unemployment benefits count, and income from the next job counts once it starts. A June layoff after six months of a $96,000 salary still leaves $48,000 of income on the year before anything else, so the credit is smaller than the current zero paycheck suggests. The credit is reconciled on your tax return, so update the estimate when you are hired. Second, the credit formula itself has changed. The enhanced subsidy levels in place from 2021 were scheduled to expire after 2025, and the credit you see when you enter your income on HealthCare.gov is the one currently in force; no table in an article should be trusted over that screen. At lower incomes, silver plans also carry cost-sharing reductions that cut the deductible itself, which changes the comparison below.
The lock-in rule is the part that catches people. During the 60-day special enrollment period you can pick either door, even after electing COBRA. Once it closes, a COBRA enrollee can move to the marketplace only at the next open enrollment, when COBRA runs out, or when a former employer stops paying part of the premium. Dropping COBRA voluntarily in April does not open a window.
The deductible reset problem
Your deductible is the amount you pay for care before the plan starts sharing costs, and your out-of-pocket maximum is the ceiling on what you pay in a plan year. Both accumulate inside one plan for one plan year. Switching to a new plan mid-year, whether a marketplace plan or a spouse's plan, restarts both at zero. COBRA is the same plan, so everything you paid toward the deductible since January carries forward.
How much this matters depends on the calendar and on your health. A layoff in February, before you have spent anything, makes the reset free. A layoff in August, after a surgery that met the deductible, makes the reset expensive, because the marketplace plan will make you pay a second deductible for care between now and December, and then reset again on January 1 like every plan does. The reset is a one-time cost of switching; the premium gap is a monthly saving. The comparison is which one is bigger for the months you are between jobs.
A worked comparison: single, 34, a $720 COBRA premium
Consider one person, 34, laid off at the end of July, comparing coverage for August through December. The employer plan had a $1,500 deductible, 20% coinsurance, and a $4,000 out-of-pocket maximum, and $1,200 of the deductible is already met. The marketplace silver plan is illustrative: $470 a month before the credit, $260 after an illustrative credit, with a $4,500 deductible and 20% coinsurance, all fresh. The real credit depends on the income you enter.
| Line | COBRA (same plan) | Marketplace silver (illustrative) |
|---|---|---|
| Monthly premium | $720 (plus up to a 2% fee) | $260 after credit ($470 before) |
| Deductible status in August | $300 left of $1,500 | $4,500, none met |
| Premiums, August through December | $3,600 | $1,300 |
| Light year: $300 of care | $300 out of pocket, $3,900 total | $300 out of pocket, $1,600 total |
| Heavy year: a $6,000 procedure in October | $1,440 out of pocket, $5,040 total | $4,800 out of pocket, $6,100 total |
| Doctors | Same network, same referrals | Different network; check each doctor |
In the light year the marketplace plan wins by $2,300, almost entirely the premium gap. In the heavy year COBRA wins by about $1,060, because the $6,000 procedure costs $300 of remaining deductible plus 20% of the rest under the old plan, and $4,500 of fresh deductible plus 20% of the rest under the new one. The break-even for these two plans is roughly $3,200 of care over the five months: below that, the cheaper premium wins; above it, the met deductible wins. If the credit turns out smaller because severance pushed the year's income up, the premium gap shrinks and the break-even drops. If a cost-sharing reduction silver applies, the marketplace deductible shrinks and the marketplace wins in more scenarios.
The decision rule
COBRA is usually the better total when:
- You have met, or nearly met, this year's deductible or out-of-pocket maximum.
- You are mid-treatment (a pregnancy, physical therapy, an ongoing specialist) with doctors who may not be in a marketplace network.
- You expect a new job with coverage within a month or two and want to wait inside the election window, paying only if something happens.
- The severance agreement includes paid premiums for a period, which turns COBRA into the same plan at the old price.
A marketplace plan is usually the better total when:
- The premium after the credit is far below the COBRA premium and the deductible would be fresh anyway because you had spent little.
- The search may run long, so the monthly gap compounds over many months, or past the 18-month COBRA limit.
- Household income for the year will be low enough that cost-sharing reductions shrink the deductible as well as the premium.
The total-cost method from the open enrollment guide (premiums plus expected care at two usage levels) is the same exercise with a shorter horizon. Put the two totals into the budget calculator as two versions of the survival budget, and check what each does to the runway in the emergency fund calculator; a $460 monthly premium difference is often the largest single line you control after rent.
The short-term plan trap
Short-term, limited-duration plans advertise premiums that undercut both doors, and they are not the same product. They can deny you for pre-existing conditions, exclude those conditions from coverage, cap what they pay per year or per lifetime, skip categories like maternity, mental health, or prescriptions, and cancel coverage after a claim. They do not count as coverage for the purpose of keeping a special enrollment period alive. Federal limits on how long they can run have changed more than once in recent years. Health care sharing arrangements have the same problem in a different wrapper: they are not insurance and are not required to pay. If the marketplace premium is the obstacle, a bronze plan is real coverage at the lowest premium the marketplace offers, with the out-of-pocket maximum that a short-term plan does not have.
The spouse-plan window closes fastest
A spouse's employer plan is often the cheapest door, because the employer is paying a share again, and it is the one people miss because its window is short, typically 30 days from the loss of coverage, and because it requires proof of loss, usually the COBRA notice or a letter from the former employer. The cost to compare is not the full family premium but the increase in the spouse's paycheck deduction: adding one adult might raise it from $180 to $490 a month, a $310 difference paid pre-tax, which is a lower real cost than the same amount paid after tax on the marketplace. The deductible resets here too, so the same break-even logic applies, and the network question is the same: confirm the doctors you care about before you enroll.
Whichever door you take, the premium becomes the largest new recurring charge in a month with no paycheck, and the rest of the post-layoff playbook is collected in the money after a layoff collection. Stoia keeps every premium and recurring charge in one live picture, launching 2026, so the survival budget reflects the plan you actually chose.
Frequently asked questions
How long do I have to decide on COBRA after losing my job?
You generally have 60 days from the later of the date your coverage ended or the date you received the COBRA election notice. Coverage is retroactive to the day the employer plan ended, and the first premium is due within 45 days after you elect. That structure lets you wait inside the window and elect only if you need care during it.
Is COBRA or a marketplace plan cheaper after a layoff?
The marketplace premium is usually lower once the premium tax credit is applied, because the credit is based on the income you expect for the year and that estimate just fell. COBRA is often cheaper in total when you have already met most of your deductible or expect significant care before year-end, because a new plan restarts the deductible at zero. Compare the total of premiums plus expected care for the months you expect to be between jobs.
Can I switch from COBRA to a marketplace plan later?
Within the 60-day special enrollment period after losing job coverage you can pick either, even if you already elected COBRA. After that window closes, you can move to a marketplace plan only during open enrollment, when your COBRA coverage runs out, or when an employer stops subsidizing it. Voluntarily dropping COBRA mid-year does not open a new enrollment window.
Does severance or unemployment count as income for marketplace subsidies?
Yes. The premium tax credit uses your expected household income for the calendar year, and that includes wages earned before the layoff, severance pay, unemployment benefits, and income from the next job. The credit is reconciled on your tax return, so update the estimate on HealthCare.gov when your income changes.
Can I use HSA money to pay COBRA premiums?
Yes. COBRA premiums are a qualified expense for a health savings account, and so are health insurance premiums paid while you are receiving federal or state unemployment benefits. The HSA balance travels with you after you leave the job, so it can cover the premium gap without touching the emergency fund.
