Who and What Does COBRA Cover?
COBRA can extend coverage to the employee who was covered under the plan, a spouse, a former spouse in certain circumstances, and dependent children. Federal COBRA generally applies to employers with 20 or more employees. Smaller employers may be subject to a state "mini-COBRA" law instead, which can have different rules and timelines, so check your state's specific requirements if your employer is smaller.
Mini-COBRA laws vary quite a bit from state to state. Some states extend continuation coverage to employers with as few as two employees, others cap the continuation period at 18 months regardless of the qualifying event, and some require you to apply directly through the insurance carrier rather than the employer. If you're not sure whether federal COBRA or a state mini-COBRA law applies to you, ask your HR department directly, since the notice you receive should specify which set of rules governs your situation.
What Events Qualify You for COBRA?
COBRA eligibility is triggered by specific qualifying events, including job loss other than for certain cases of gross misconduct, a reduction in work hours that causes loss of coverage, divorce or legal separation, death of the covered employee, a dependent child losing eligible-dependent status, and certain situations involving Medicare entitlement.
How Long Does COBRA Coverage Last?
Standard COBRA continuation periods are generally 18 or 36 months depending on the qualifying event, with possible extensions in cases involving disability or certain secondary qualifying events. Coverage can also end early in specific circumstances, such as failure to pay premiums on time or the employer discontinuing group health coverage entirely.
For example, if you lose your job through a layoff, you and your dependents are generally eligible for up to 18 months of COBRA continuation. If a second qualifying event happens during that window, such as the covered employee becoming entitled to Medicare, a dependent's coverage can sometimes extend up to 36 months total from the original qualifying event. Track these dates carefully, since the extension isn't automatic. You typically need to notify the plan administrator of the second qualifying event within 60 days for the extension to apply.
What Are the COBRA Notice and Election Deadlines?
COBRA runs on strict timelines, and missing one can mean losing your right to elect coverage entirely. Your employer or plan administrator is responsible for sending an election notice after a qualifying event, and you generally have at least 60 days to elect coverage once you receive that notice. Coverage, once elected, is typically applied retroactively to the date you lost your job-based coverage. There's an initial premium payment deadline after election, and ongoing monthly payments have deadlines too, usually with a grace period.
Federal COBRA plans must generally give qualified beneficiaries at least 60 days to elect coverage, according to the U.S. Department of Labor. Keep copies of every notice you receive and every payment you make, since these records matter if a dispute ever comes up.
How Much Does COBRA Cost?
This is where COBRA often surprises people. While employed, your employer typically pays a significant share of your premium, and you only see your smaller payroll deduction. Under COBRA, you generally pay the portion you previously paid through payroll, plus the employer's former contribution, plus an administrative charge, often up to 2% of the total premium.
For example, if your paycheck deduction was $150 a month but your employer was covering an additional $550, your COBRA premium could jump to roughly $714 a month once the employer's share and the administrative fee are added in. Deductibles and other out-of-pocket costs continue under the plan's normal rules.
It's also worth running the math over the full period you'd need coverage, not just the first month. If your COBRA premium is $714 a month and you expect to need coverage for eight months while job hunting, that's roughly $5,712 total, a number worth comparing directly against a Marketplace plan's total cost over the same stretch, including any subsidy you might qualify for. Some employers also offer a severance package that temporarily covers COBRA premiums for a set number of months, so check your severance paperwork closely before assuming you're paying the full cost yourself.
What Are the Advantages of COBRA?
COBRA lets you keep the exact same plan and provider network, so ongoing treatment can continue without interruption. Progress toward your deductible and out-of-pocket maximum carries over, and it can smooth over a short employment gap or reduce disruption during pregnancy or a serious illness.
What Are the Disadvantages of COBRA?
The monthly cost is often significantly higher than what you paid as an employee, and coverage is limited in duration. You remain dependent on your former employer continuing to offer that plan, and COBRA may be less affordable than Marketplace coverage, especially with subsidies. The strict deadlines are also easy to miss during an already stressful transition.
What Are the Alternatives to COBRA?
Alternatives worth comparing include a spouse's employer plan if you qualify for a special enrollment, the Health Insurance Marketplace, Medicaid depending on income and state rules, the Children's Health Insurance Program (CHIP), Medicare if you're eligible, a new employer's plan, or short-term health insurance, keeping in mind its limitations and exclusions, including limited coverage for pre-existing conditions.
How Does COBRA Compare to Marketplace Coverage?
Losing job-based coverage generally triggers a special enrollment period for the Health Insurance Marketplace, and Marketplace plans may come with premium tax credits that substantially lower your monthly cost, something COBRA premiums aren't eligible for. When comparing the two, look closely at premium, deductible, provider network, prescription formulary, and total expected annual cost, not just the sticker price. One important note: voluntarily dropping COBRA later doesn't always create a new Marketplace special-enrollment opportunity, so this is a decision worth making carefully the first time, ideally during open enrollment or your initial special enrollment window.
How Does COBRA Interact with Medicare?
COBRA is not treated the same as active-employment coverage when it comes to Medicare enrollment timing. Delaying Medicare enrollment while relying on COBRA can potentially expose you to late-enrollment penalties and coordination-of-benefits complications. If you're approaching Medicare eligibility while considering COBRA, it's worth speaking with Medicare directly or a State Health Insurance Assistance Program (SHIP) counselor before making a decision.
COBRA Decision Worksheet
Before electing or declining COBRA, compare the monthly premium under COBRA versus Marketplace options, how much of your deductible you have already met this year, and the medical care you realistically expect to need. Weigh whether your current provider network matters to you, prescription coverage differences, how many months you'll actually need coverage, your Marketplace subsidy eligibility, and whether family members might be better served by different coverage.
A simple way to compare the two: write down your COBRA premium, then look up a similar Marketplace plan's premium after any subsidy, side by side for the number of months you expect to need coverage. If the gap is small, network continuity and not having to meet a new deductible often tip the decision toward COBRA. If the gap is large, the savings from Marketplace coverage may be worth changing providers or restarting your deductible. Financial Confidence's Health Insurance Plan Comparison Tool can help you compare the total estimated annual cost of COBRA against a Marketplace plan, not just the premiums.
What Should You Do Right After Losing Coverage?
In the first week, confirm your last day of active coverage and watch for your COBRA election notice. In the first 30 days, compare COBRA against Marketplace options and gather cost estimates for both. Before your election deadline, make your decision, and if electing COBRA, submit your election and initial payment on time.
Frequently Asked Questions
You generally have at least 60 days from the date you receive your COBRA election notice to decide, and coverage is typically applied retroactively to your coverage-loss date if you elect it.
Not always, but it often is, because you're paying both your former payroll share and the portion your employer used to cover, plus an administrative fee. Marketplace plans may also come with premium tax credits that lower your effective cost, something COBRA doesn't offer.
COBRA plans typically include a grace period for late payments, but missing the final deadline within that grace period can result in permanent loss of coverage, so mark payment due dates carefully.
Voluntarily dropping COBRA outside of open enrollment doesn't always create a new Marketplace special enrollment period, so this is a decision worth researching carefully before you elect COBRA in the first place.
COBRA can extend to a covered employee, spouse, former spouse in certain situations, and dependent children, generally under the same plan they were covered by before the qualifying event.
This deserves careful attention, since COBRA isn't treated the same as active-employment coverage for Medicare enrollment timing and could expose you to late-enrollment penalties. Speak with Medicare or a SHIP counselor before delaying Medicare enrollment in favor of COBRA.
