COBRA may let you temporarily keep your former employer’s health coverage; a Marketplace plan is a new insurance choice with its own costs, network, and enrollment rules. Neither is automatically cheaper or better. Compare the actual monthly price, remaining deductible, ongoing treatment, and confirmed start date.
This guide compares common U.S. coverage decisions, not individual eligibility. Federal COBRA does not apply to every employer or arrangement; state continuation rules can differ. Your continuation notice and official Marketplace application are the starting points.
Compare the choices side by side
| Question | COBRA continuation | Marketplace plan |
|---|---|---|
| What coverage is it? | Continuation of the employer plan, subject to its terms and ongoing changes | A new individual-market plan |
| Monthly cost | Use the continuation notice’s actual amount and check whether employer contributions will end | Use the actual premium after any savings for which the application finds you eligible |
| Doctors and drugs | Confirm the existing plan’s current network and formulary | Check every important provider and prescription in the new plan |
| Deductible progress | Ask how current plan-year accumulators continue | Do not assume prior employer-plan spending transfers |
| Enrollment timing | Follow the election notice and payment requirements | Use Open Enrollment or a qualifying Special Enrollment Period |
Coverage-loss enrollment and switching later
HealthCare.gov says you can enroll in a Marketplace plan within 60 days of losing job-based coverage. Start comparing before coverage ends rather than waiting for a COBRA decision. Confirm the Special Enrollment Period available to you, any required documents, and the date the new plan can actually begin.
During Open Enrollment, you can choose a Marketplace plan even if you are on COBRA. Outside Open Enrollment, the reason you leave COBRA matters. HealthCare.gov identifies situations such as COBRA running out, an employer stopping contributions so you must pay the full cost, or still being within the original job-coverage-loss enrollment window.
Compare total cost, not just the premium
Suppose, purely as an example, COBRA costs $700 per month and a Marketplace plan costs $400 after verified savings. Over three months, the premium difference is $900. If the Marketplace plan has a fresh deductible and a key treatment costs you $1,200 more under its benefits, the lower premium alone would not make it cheaper for that period.
The reverse can also happen: a large premium difference may outweigh deductible progress when little care is expected. These numbers are illustrative, not quotes. Use an expected-care scenario and a high-cost scenario for each actual plan.
Check Marketplace savings using the full year
Losing a job does not automatically mean qualifying for the largest premium tax credit. The application asks about household circumstances and expected annual income, not only your income in the month after job loss. Account for wages already earned and other income the application requires; update the estimate when circumstances change.
Check how enrolling in COBRA affects Marketplace savings for overlapping months rather than assuming both can be used together. Our premium tax credit guide explains the general framework; the official application determines the available savings. Medicaid and CHIP enrollment is available year-round for eligible applicants.
If you are in active treatment
- Verify the treating clinician, facility, laboratory, and prescriptions in each option.
- Ask a potential new plan whether existing referrals or authorizations must be obtained again.
- Compare the remaining out-of-pocket limit, not just the deductible.
- Ask the current plan what happens when its plan year renews.
- Coordinate pending claims and appointments with the providers’ billing staff.
Before ending either option
Get the new effective date and first-premium requirement in writing, confirm enrollment is complete, and coordinate the old coverage end date. If you are waiting for Medicaid or CHIP, HealthCare.gov advises waiting for a final eligibility decision before ending COBRA. Keep copies of notices and payments.
For a broader first-week checklist, start with what to do after losing job-based health insurance. This comparison does not replace a continuation notice or a plan-specific eligibility determination.
