COBRA vs. ACA Marketplace After Job Loss
COBRA election-window and duration rules from federal ERISA/COBRA law; ACA special enrollment mechanics from IRS/HHS guidance.
Losing job-based coverage opens two separate 60-day windows at once. Which one actually makes financial sense depends on a number most people forget to check.

Two clocks start running at once
Losing job-based health coverage triggers two separate 60-day windows simultaneously. You generally have 60 days after receiving the COBRA qualifying-event notice to elect COBRA continuation coverage. Separately, losing job-based coverage is itself a qualifying life event that opens a 60-day special enrollment period to sign up for an ACA marketplace plan, outside the normal annual open enrollment window.
Both exist specifically because an involuntary coverage loss is treated as urgent, not something that has to wait for a fixed calendar date.
COBRA keeps your exact plan. That is not automatically the cheaper choice.
COBRA's real advantage is continuity: identical plan, identical network, identical benefits, no new deductible clock starting over mid-year. That continuity comes at the full premium cost, both your former payroll share and your employer's former contribution, plus a 2% administrative fee, as this site's own COBRA insurance cost explainer covers in detail.
A marketplace plan, by contrast, is priced against your new household income, which after a job loss is often meaningfully lower, and can come out cheaper once a premium tax credit applies, even accounting for a different plan or network.
To calculate your own COBRA cost for comparison, the COBRA insurance cost calculator runs the full statutory formula from your actual numbers.
The detail most people forget to check: your subsidy just changed
ACA premium tax credits are based on your household's actual income for the coverage year, not your prior salary while employed. A period of reduced or no income following a job loss can genuinely increase the subsidy you qualify for, sometimes substantially, compared to what the same household would have qualified for while still employed and earning a full salary.
This is the single most commonly missed factor in the COBRA-vs-marketplace decision: comparing COBRA's cost against a marketplace quote based on your old salary, rather than your new, lower actual income, understates how much cheaper the marketplace option might genuinely be.
Frequently asked questions
How much time do I have to decide between COBRA and an ACA marketplace plan after losing my job?
You generally have 60 days to elect COBRA after receiving the qualifying-event notice, and separately, losing job-based coverage triggers a 60-day special enrollment period to sign up for an ACA marketplace plan outside the normal annual window.
Both windows exist because losing coverage involuntarily is treated as a real, time-sensitive event, not something you have to wait for open enrollment to address.
Is COBRA automatically the better choice since it keeps my exact same plan?
Not automatically, keeping the identical plan and network is a real benefit, but it comes at the full premium cost, as explained in this site's own COBRA cost explainer.
A marketplace plan, priced against your new, likely lower post-job-loss income, can come out meaningfully cheaper once a premium tax credit is factored in, even though it may mean switching plans or networks.
Does losing my job actually help me qualify for a bigger ACA subsidy?
It can, for the same underlying reason retiring early can. ACA premium tax credits are based on your household's actual income for the coverage year, not your prior salary, so a period of reduced or no income after a job loss can genuinely increase the subsidy you qualify for, sometimes substantially, compared to what you would have qualified for while still employed.
Can I switch from COBRA to a marketplace plan later if I choose COBRA first?
Generally yes, but the special enrollment period tied to the job loss itself is typically the cleanest window to do this. Once that specific 60-day window closes, switching later usually requires either open enrollment or a new qualifying event, such as your COBRA coverage naturally ending, so choosing COBRA does not permanently lock out a later marketplace switch, but the easiest opportunity is right after the job loss itself.
