Losing your job is stressful enough without having to worry about health insurance. If you have recently been laid off, had your hours reduced, or left a position voluntarily, you have probably received a thick envelope in the mail about something called COBRA. But what exactly is it, how much does it cost, and is it actually worth signing up for?
This guide breaks down everything you need to know about COBRA continuation coverage so you can make an informed decision about your health insurance options during a transitional period.
What Is COBRA Insurance?
COBRA stands for the Consolidated Omnibus Budget Reconciliation Act, a federal law passed in 1986 that gives workers and their families the right to continue their employer-sponsored group health insurance for a limited time after losing coverage. It is not a separate insurance plan. Instead, COBRA lets you keep the exact same health insurance plan you had through your employer, with the same network of doctors, the same benefits, and the same coverage levels.
The key difference is who pays for it. When you are employed, your employer typically covers 70% to 83% of the premium cost, and you pay the remainder through payroll deductions. With COBRA, you take on the full cost of the premium yourself, plus a small administrative fee.
COBRA also applies to dental plans, vision plans, and certain health flexible spending arrangements, and you can generally elect each benefit separately. If the dental coverage at your old job was excellent but the medical plan was overpriced, you are allowed to continue one without the other.
Who Is Eligible for COBRA?
COBRA eligibility depends on several factors. First, your former employer must have had 20 or more employees on more than 50% of typical business days in the prior calendar year. Smaller employers are generally not subject to federal COBRA requirements, although many states have mini-COBRA laws that extend similar protections to employees of smaller companies.
You can qualify for COBRA coverage after any of these qualifying events:
- Voluntary or involuntary job loss (except for gross misconduct)
- Reduction in hours that causes you to lose eligibility for the employer plan
- Transition between jobs during a coverage gap
- Death of the covered employee (for dependents)
- Divorce or legal separation from the covered employee
- A dependent child aging out of the plan (usually at age 26)
If your former employer had fewer than 20 employees, do not assume you are out of options. Most states have mini-COBRA laws, often called state continuation, and the details vary widely: some states mirror the federal 18-month standard, while others offer only a few months of continuation. Your state insurance department or the plan administrator can tell you what applies where you live. Federal employees are not covered by COBRA itself but have a parallel program called Temporary Continuation of Coverage under the FEHB program, which works in a broadly similar way.
How Long Does COBRA Last?
The standard COBRA period is 18 months when the qualifying event is job loss or a reduction in hours. But several situations extend coverage to 36 months, and this is one of the most commonly misunderstood parts of the law. Spouses and dependent children are entitled to up to 36 months of COBRA when the qualifying event is divorce or legal separation, the death of the covered employee, the employee becoming entitled to Medicare, or a child aging out of dependent status. If you are going through a divorce and assumed you had only 18 months of continuation available, you actually have twice that long.
There is also a disability extension. If the Social Security Administration determines that you or a covered family member was disabled within the first 60 days of COBRA coverage, the 18-month period can be extended to a total of 29 months, although the plan is allowed to charge up to 150% of the premium during the extension months. And if a second qualifying event, such as a divorce or the death of the former employee, occurs during the initial 18-month period, dependents can extend their coverage to 36 months measured from the original event.
One procedural detail trips up many families: for divorce, legal separation, or a child losing dependent status, you must notify the plan administrator within 60 days of the event. Miss that notification window and you forfeit your COBRA rights entirely, even though the law would otherwise have given you 36 months.
The True Cost of COBRA
This is where COBRA sticker shock hits most people. Under COBRA, you pay 102% of the total plan premium: the full premium (both the employer share and your share) plus a 2% administrative fee. The average total premium for employer-sponsored individual coverage is approximately $700 to $800 per month, and family coverage commonly runs roughly $2,000 per month or more. Under COBRA, you pay the full amount plus the fee, which means family COBRA can easily exceed $24,000 per year.
That said, the headline premium is not the whole financial picture. Because COBRA is literally the same plan, everything you have already paid toward your deductible and out-of-pocket maximum this year carries over. If you switch to a marketplace plan mid-year, you start over at zero on a new deductible and a new out-of-pocket maximum, which for ACA plans in 2026 can be as high as $10,600 for an individual and $21,200 for a family. If you are in the middle of expensive treatment and have already met your deductible, a cheaper marketplace premium can end up costing far more in total.
The 60-Day Election Window and the Retroactive Strategy
You have 60 days to elect COBRA, counted from the later of the date you lose coverage or the date you receive your election notice. After electing, you have another 45 days to make your first premium payment, and coverage is retroactive to the date your employer coverage ended.
This creates a strategy worth knowing if you are facing a short gap between jobs. Because COBRA is retroactive, you can decline to elect immediately, wait out the window, and only elect and pay if something serious happens. If you stay healthy, you save the premiums entirely. If you break a leg in week five, you elect COBRA, pay retroactively, and the plan covers the claim as if you had never lost coverage.
Use this approach with eyes open. You must pay every retroactive month of premium, not just the month in which you needed care. Providers may treat you as uninsured until your election processes, so you may have to pay bills up front and seek reimbursement later. The dates are unforgiving: track exactly when your 60 days began, because there is no grace period beyond what the law provides. And remember that your 60-day marketplace Special Enrollment Period runs at the same time, so if you let both windows lapse, your remaining options narrow considerably.
COBRA vs. the ACA Marketplace
Losing employer-sponsored coverage qualifies you for a Special Enrollment Period on the ACA marketplace, giving you 60 days to enroll in a new plan. This is the most important comparison to make before choosing COBRA.
Marketplace premium tax credits are based on your projected household income for the year, and a job loss usually means lower projected income, which means larger subsidies. Be aware, however, that the enhanced subsidies in place during the early 2020s expired at the end of 2025. In 2026, the subsidy cliff at 400% of the federal poverty level is back: a household even slightly above that threshold, roughly $62,600 for a single person or around $129,000 for a family of four, receives no premium tax credit at all. If severance, investment income, or a working spouse keeps your household above the cliff, marketplace coverage may not be as cheap as you expect, and COBRA becomes more competitive.
Networks matter too. Marketplace plans often use narrower networks than large employer plans. If continuity with a particular oncologist, OB-GYN, or hospital system is essential to you, confirm they are in network before walking away from COBRA.
COBRA and Medicare Do Not Mix Well
If you are 65 or older when you lose your job, be very careful here. COBRA does not count as creditable coverage for Medicare Part B. If you keep COBRA instead of enrolling in Part B when you are first eligible, you can face a permanent late enrollment penalty and a wait for a future enrollment window before coverage begins. In addition, once you are entitled to Medicare, COBRA pays secondary, meaning the plan may refuse to pay the share Medicare would have covered, leaving you exposed on large claims. The general rule for most people over 65 is to enroll in Medicare first and treat COBRA only as a possible supplement for a spouse or for benefits Medicare does not cover, such as dental.
When COBRA Ends Early
COBRA can terminate before the 18 or 36 months run out. The most common reasons are nonpayment of premiums, the former employer terminating all of its group health plans (if the company shuts down entirely, there is no plan left to continue), becoming entitled to Medicare after electing COBRA, or obtaining coverage under another group plan.
Here is the trap: voluntarily dropping COBRA mid-stream, or losing it because you missed a payment, does not qualify you for a marketplace Special Enrollment Period. Exhausting the full COBRA period does. So if you elect COBRA, plan your exit. You can switch to a marketplace plan during the annual open enrollment period, which for 2027 coverage runs from November 1, 2026 through January 15, 2027, or when your COBRA runs out, but you cannot simply quit paying in July and sign up for a marketplace plan that week.
So Is COBRA Worth It?
COBRA tends to be worth the cost in a few specific situations: you are in the middle of treatment and need to keep your exact doctors, you have already met your deductible or out-of-pocket maximum for the year, you are pregnant and committed to a specific hospital and care team, your household income is too high for marketplace subsidies, or you only need to bridge a short gap before new employer coverage begins.
COBRA is usually not worth it if you are relatively healthy, your income has dropped enough to qualify for meaningful marketplace subsidies, or your income is now low enough for Medicaid, which you can enroll in year-round in every state. Run the real numbers for your own situation: the COBRA premium printed on your election notice, the subsidized marketplace premium at your new projected income, and what each option means for your deductible progress and your doctors. The right answer is different for a healthy 28-year-old between jobs and a 58-year-old in the middle of cardiac care, and that is exactly why the comparison deserves an hour of your time.
