COBRA vs marketplace after quitting
The short answer: when you quit a US job, you can continue your employer plan through COBRA or buy an ACA marketplace plan, and losing job-based coverage opens a special enrollment window for both. COBRA keeps your exact plan, doctors, and met deductible but charges the full premium with no help. A marketplace plan usually wins on cost because your lower income after quitting can qualify you for premium tax credits COBRA can never match. Price both before you choose, and watch the 60-day clocks.
This guide covers the United States, where most health cover is tied to employment. If you are elsewhere, see the country guides.
| Factor | COBRA | Marketplace (ACA) |
|---|---|---|
| What it is | Your exact employer plan, continued | A new plan you buy on the exchange |
| Typical cost | Full premium plus up to 2% fee, no subsidy | Premium minus any income-based tax credit |
| Subsidies | None | Yes, based on estimated annual income |
| Your doctors and network | Unchanged | May change; check each plan |
| Deductible this year | Carries over, already met counts | Usually resets to zero |
| Enrollment window | About 60 days to elect | 60-day special enrollment period |
| How long it lasts | Up to 18 months | As long as you keep paying |
| Best when | Mid-treatment, or income too high for subsidies | Income drops after quitting, cost matters most |
What each option actually is
COBRA is the federal right to keep your existing employer health plan for a period after you leave, usually up to 18 months. Nothing about the plan changes: same network, same doctors, same deductible. What changes is the price. While employed, your employer paid most of the premium; on COBRA you pay the whole thing, plus an administration fee of up to 2 percent, so the figure can be three or four times what came out of your paycheck. The US Department of Labor sets out the COBRA continuation rules.
A marketplace plan is health cover you buy yourself through the Affordable Care Act exchange at HealthCare.gov or your state's version. Losing job-based coverage triggers a special enrollment period, so you do not have to wait for open enrollment. The decisive feature is that premiums can be reduced by income-based premium tax credits, and after quitting your expected income is often low enough to qualify for substantial help.
The cost gap, and why subsidies decide it
The single biggest factor is the premium tax credit. COBRA has no equivalent: you pay the unsubsidised cost of a plan that was built for a salaried employee. On the marketplace, the credit is calculated from your estimated household income for the coverage year, not the salary you just left behind. Because quitting usually cuts your income, the same person can qualify for a credit that turns a several-hundred-dollar premium into something far smaller, sometimes a fraction of the COBRA quote.
That is why the honest comparison is not COBRA versus the full marketplace price, but COBRA versus the marketplace price after your subsidy. Estimate your post-quit income, check the credit you would get, and only then compare. The one case where COBRA can still win on value is when you have already met a large deductible this year or you are mid-treatment with specific doctors, because a new plan resets the deductible and may drop your providers. Price your COBRA continuation precisely with the COBRA cost calculator before you assume it is unaffordable.
The deadlines that trap people
Both options run on a 60-day clock from around the date your coverage ends, and missing them is the most common and most expensive mistake. Three timing facts matter:
- COBRA is retroactive. You have roughly 60 days to elect it, and it backdates to the day your coverage ended. So you can stay technically uninsured during the window and elect COBRA only if you actually incur a medical bill, a useful hedge if you are about to start a cheaper plan.
- The marketplace window is also 60 days, and you can enroll up to 60 days before your job coverage ends, which lets you start a new plan with no gap.
- Electing COBRA first can lock you in. Voluntarily dropping COBRA mid-year does not open a new marketplace special enrollment period, so if you think the marketplace is cheaper, choose it during the initial window rather than defaulting to COBRA and trying to switch later.
How to decide
- Get the real COBRA number. Your employer or plan administrator must give you the exact monthly figure. Do not guess from your old paycheck deduction, which only showed your share.
- Estimate your post-quit income and check the subsidy. Use your honest expected income for the year on the marketplace to see the credit and the net premium. This is where most of the savings live.
- Weigh continuity against cost. If you are mid-treatment, have met a big deductible, or cannot risk changing doctors this year, COBRA's continuity may be worth its higher price. Otherwise, cost usually points to the marketplace.
- Act inside 60 days, and avoid the gap. Enroll in your chosen option before or as your coverage ends. If you want a safety hedge, hold the COBRA election in reserve since it backdates.
Price your COBRA continuation first
The comparison starts with knowing what COBRA would actually cost you per month. The calculator turns your plan details into a clear figure and an annual total, so you can hold it against a subsidised marketplace quote.

Is COBRA or a marketplace plan cheaper after quitting?
For most people who quit, a marketplace plan is cheaper, often dramatically so, because your lower income after leaving work can qualify you for premium tax credits that COBRA never offers. COBRA charges the full premium your employer used to subsidise, plus up to a 2 percent administration fee. The marketplace only wins clearly when your income is too high for subsidies and you want to keep your exact plan and deductible.
Should I choose COBRA or a marketplace plan when I leave my job?
Compare three things: the COBRA premium your employer will quote, the marketplace premium after any subsidy you qualify for at your new income, and whether keeping your current doctors and met deductible matters this year. Quitting triggers a special enrollment period for the marketplace, so you can price both before deciding. Most people find the subsidised marketplace plan cheaper unless they are mid-treatment on their current plan.
How long do I have to enroll after losing job-based coverage?
Losing job-based coverage opens a special enrollment period of 60 days for a marketplace plan, and you generally have 60 days to elect COBRA. Both clocks run from around your coverage-loss date, so do not let them lapse. You can also enroll in a marketplace plan up to 60 days before your coverage ends, which avoids a gap.
Can I switch from COBRA to a marketplace plan later?
Yes, but the timing matters. Voluntarily dropping COBRA mid-year does not by itself open a marketplace special enrollment period; you generally have to wait for open enrollment or for your COBRA to run out, which does count as a qualifying event. The cleanest switch is to choose the marketplace during your initial 60-day window rather than electing COBRA first and trying to move later.
People also ask
Does COBRA let me keep my current doctors and deductible?
Yes, that is COBRA's main advantage. It continues the exact same employer plan, so your network, doctors, and any deductible you have already met this year carry over unchanged. A new marketplace plan usually resets your deductible and may use a different network, which is why someone mid-treatment often pays more for COBRA on purpose.
What income do the marketplace subsidies use?
Premium tax credits are based on your estimated annual household income for the coverage year, not last year's salary. After quitting, your expected income is often much lower, which is exactly what can make a marketplace plan affordable. You estimate that income when you apply, and it is reconciled on your tax return, so estimate honestly.
Is there a gap in coverage if I wait to decide?
There need not be. COBRA is retroactive: you have a window to elect it and it backdates to the day your coverage ended, so you can stay uninsured on paper, then elect COBRA only if you incur a bill. A marketplace plan, by contrast, starts on a future date, so to avoid any gap you enroll before or right as your job coverage ends.
