- Losing job-based coverage starts two 60-day clocks at once: one to elect COBRA, one to enroll in an ACA marketplace plan through a Special Enrollment Period.
- COBRA keeps your exact plan, network, and any deductible you have already met this year. You pay the full premium plus a 2% admin fee, with no employer subsidy.
- A marketplace plan usually costs far less once premium tax credits are applied, because your lower post-layoff income raises the subsidy. But it resets your deductible to zero.
- COBRA is retroactive within the 60-day window. You can wait, stay uninsured on paper, and elect it later if you have a claim, which makes it a free hedge while you shop.

Renata, 41, got laid off on a Friday and a COBRA election packet in the mail the next week. The number on it stopped her: $742 a month to keep the exact plan that had cost her $180 from her paycheck. Her employer had been quietly covering the other $562. Her instinct was that COBRA was the safe, simple choice because it kept her doctors. The simple choice and the cheap choice are often not the same one, and she had 60 days and four numbers to tell them apart.
A Special Enrollment Period, or SEP, is simply a window outside the normal year-end open enrollment when a life change lets you buy a marketplace plan. A layoff is one of the events that opens it.
The two 60-day clocks and the retroactive hedge
Here is the part most people miss, and it is the most useful fact in this entire decision. COBRA is retroactive within your 60-day election window. If you elect and pay within 60 days of losing coverage, your COBRA coverage backdates to the day your old plan ended, with no gap.
That means you do not have to decide on day one. You can spend a few weeks comparing marketplace plans while technically uninsured, and if you have a major medical event in that gap, you can still elect COBRA afterward and have it cover the bill retroactively. In practice, COBRA is a free safety net stretched across your shopping window. Use the time.
The catch on the other side: the marketplace SEP also runs 60 days, and if you let both clocks expire you can be locked out until the next open enrollment. Do not let the COBRA hedge make you miss the marketplace deadline.
The four numbers that decide it
Loyalty to your old plan is not a number. These four are.
First, the full COBRA premium. It is on your election letter: your old paycheck deduction plus the part your employer paid plus a 2% administrative fee. This is the real cost, and it is often three to five times what came out of your check.
Second, your estimated household income for the rest of the year. Marketplace premium tax credits – the subsidy that lowers your monthly premium – are based on your annual income, and a layoff usually drops it. Lower income means a larger subsidy. Estimate honestly; this number drives everything on the marketplace side.
Third, the benchmark marketplace premium after the subsidy. On HealthCare.gov or your state exchange, enter your income and see the actual monthly cost of a Silver plan with the tax credit applied. That is the number to compare against COBRA, not the sticker price.
Fourth, the deductible you have already met this year. A deductible is what you pay out of pocket before insurance starts sharing costs. COBRA continues your current plan, so a met deductible carries over. A new marketplace plan resets it to zero on the day it starts. If you have already paid down a $4,000 deductible by mid-year, starting over is a real cost. Our guide to out-of-pocket maximums explains how that resets too.
COBRA vs marketplace, side by side
| Factor | COBRA | ACA marketplace plan |
|---|---|---|
| Monthly cost | Full premium + 2% fee, no subsidy | Often much lower after income-based tax credit |
| Your doctors and network | Identical – same plan you had | May change; check each plan’s network |
| Deductible already met | Carries over for the rest of the year | Resets to zero on the new plan |
| Subsidy eligibility | None | Yes, scaled to your lower post-layoff income |
| How long it lasts | Up to 18 months | As long as you keep paying and qualify |
| Best for | Mid-treatment, met deductible, must keep specific doctors | Healthy, lower income now, no care in progress |
When COBRA is the right call
COBRA wins when continuity is worth more than the premium. If you are in the middle of treatment – a pregnancy, a surgery series, cancer care, ongoing specialist visits – switching plans mid-stream can mean a new network, new prior authorizations, and a fresh deductible on top of bills you have already partly paid. COBRA keeps all of it intact.
It also wins when you have already met most of your deductible this year and expect more care before December. Starting a new plan at zero could cost you more in resumed out-of-pocket spending than COBRA’s higher premium. And if a specific doctor or hospital you rely on is out of network on every affordable marketplace plan, COBRA may be the only way to keep them without paying out of network.
When the marketplace wins
For most healthy people whose income dropped with the layoff, the marketplace is dramatically cheaper. The subsidy that felt irrelevant while you were employed can cut a $700 premium to a fraction of that, and a new deductible is a non-issue if you rarely use care.
Price the marketplace plan first, every time. If you also want to compare private plan options outside the exchange, Health Plans of America lets you compare coverage and pricing alongside what you find on the marketplace. A layoff is one of several events that open a Special Enrollment Period; our mid-year ACA plan switch guide covers the others and the 60-day rule in detail.
FAQ
Do I have to choose COBRA or the marketplace right away? No. Both give you 60 days from the loss of coverage. COBRA is retroactive within that window, so you can shop marketplace plans first and still elect COBRA later if a medical need comes up. Just do not let either 60-day clock expire, or you may be locked out until open enrollment.
Why is COBRA so much more expensive than my old paycheck deduction? Your employer was paying most of the premium while you worked. COBRA makes you pay the entire premium plus a 2% administrative fee, so the full cost that was hidden in your benefits now lands on you. That is why the number on the election letter is often three to five times your old deduction.
Will I qualify for a marketplace subsidy if I just got laid off? Very likely, because subsidies are based on your expected annual income and a layoff usually lowers it. Estimate your income for the full year, including any severance and unemployment, and enter it on HealthCare.gov or your state exchange to see your actual subsidized premium. Lower income means a larger tax credit.
If I take a marketplace plan, what happens to the deductible I already met this year? It resets to zero. A new marketplace plan starts your out-of-pocket spending over, so any deductible you paid down on your old plan does not carry. COBRA is the only option that continues your current plan and keeps a met deductible intact for the rest of the year.
Can I switch from COBRA to a marketplace plan later if it gets too expensive? Yes, but timing matters. Voluntarily dropping COBRA does not by itself open a Special Enrollment Period, but exhausting your COBRA coverage does. Otherwise you would wait for the next open enrollment. The cleaner move is to compare both during your initial 60-day window rather than committing to COBRA and trying to switch later.
