COBRA vs. Marketplace Health Insurance: How They Differ and Which One Fits You

Losing a job often brings two health insurance choices at once, and people mix them up because both can keep a person covered after employment ends. COBRA is a way to stay on a former employer’s group plan for a limited time. A Marketplace plan is a separate individual plan bought through HealthCare.gov or a state marketplace. The monthly cost, the doctors in the network, and the deadline to sign up can differ a lot between the two, so the right choice depends on a person’s health needs, income, and how long coverage is needed.

How COBRA works

COBRA comes from the Consolidated Omnibus Budget Reconciliation Act, a federal law that lets eligible workers and family members continue group health coverage after a qualifying event. Job loss and a cut in work hours are common qualifying events. Other events include divorce, legal separation, and the death of the covered employee.

Under COBRA, a person keeps the same plan, the same network of doctors, and the same drug coverage that the employer group had. That continuity can matter for a person in the middle of treatment or with doctors who are not in another plan’s network. The trade-off is cost. A person on COBRA generally pays the full premium for the group plan, plus a 2 percent administrative fee, because the employer no longer pays its share.

Federal COBRA generally applies to employers with 20 or more employees. Many states have similar continuation rules for smaller employers. For job loss or reduced hours, COBRA coverage generally lasts up to 18 months. For certain other qualifying events, it can last up to 36 months. A person generally has at least 60 days to elect COBRA after receiving notice of the right to continue coverage.

How Marketplace coverage works

A Marketplace plan is individual health insurance sold through HealthCare.gov or a state-run marketplace under the Affordable Care Act. These plans must cover a set of essential health benefits, and a plan cannot turn a person away or charge more because of a pre-existing condition. Plan networks, deductibles, copays, and monthly premiums vary by plan, by location, and by metal tier, from bronze plans with lower premiums and higher out-of-pocket costs to gold and platinum plans with higher premiums and lower out-of-pocket costs.

People can enroll during the annual open enrollment period. Dates for that period change each year, so a person should check HealthCare.gov or the state marketplace for the current dates. Outside open enrollment, a person generally needs a qualifying life event, such as losing job-based coverage, to get a special enrollment period. That special period generally lasts 60 days from the qualifying event.

Income can change the cost of a Marketplace plan in a way it does not change COBRA. People with qualifying incomes may receive a premium tax credit that lowers the monthly premium for a Marketplace plan. That credit does not apply to COBRA premiums. Premiums, tax credit amounts, and plan choices change each year.

Side-by-side comparison

	COBRA	Marketplace health insurance
What it is	Continuation of a former employer’s group health plan under federal law	An individual plan bought through HealthCare.gov or a state marketplace under the Affordable Care Act
Who qualifies or gets it	Eligible workers and family members after a qualifying event, generally at employers with 20 or more employees, with similar state rules for some smaller employers	People who need individual coverage and meet residency and legal status rules, with a special enrollment period after losing job-based coverage
Costs	Generally the full group premium plus a 2 percent administrative fee, with no premium tax credit	Monthly premiums vary by plan, age, location, and metal tier, and a premium tax credit may lower the cost for people with qualifying incomes
Pros	Keeps the same plan, doctors, and drug coverage, with no break in a current course of treatment	Offers a range of plans and prices, and may cost less each month for people who qualify for a premium tax credit
Cons	Often costs far more each month than the worker paid while employed, and coverage ends after a set period	Means a new plan and possibly a new network of doctors, and enrollment is limited to open enrollment or a special enrollment period

Verdict: which one fits your situation

Choose COBRA if keeping the same doctors and the same plan matters most in the short term, and the full premium is affordable for a few months. That case is common for a person in the middle of treatment, a person with a planned surgery under the current plan, or a person who expects new employer coverage soon and wants no change in care during the gap.

Choose a Marketplace plan if a lower monthly premium matters more than keeping the same plan, or if coverage is needed for a longer stretch. That case is common for a person with a qualifying income for a premium tax credit, a person whose doctors are in a Marketplace plan’s network, or a person who wants to compare several plans and prices before deciding.

Before deciding, check three things: whether current doctors and medicines are covered, the total monthly premium plus the deductible, and the deadline to enroll. Missing the 60-day election or enrollment window can close one option, so a person facing a job loss should compare both paths as soon as the notice arrives.
