COBRA stands for the Consolidated Omnibus Budget Reconciliation Act, the 1985 federal law that established the right for workers and their covered dependents to continue employer-sponsored health insurance after certain events that would otherwise end that coverage. In practical terms, COBRA means that when you leave a job, get laid off, have your hours reduced below the threshold for benefits eligibility, or experience another qualifying event, you can stay on the same group health plan you had as an employee for a defined period of time, usually 18 months, sometimes longer.
The continuation coverage is identical to what you had as an employee. Same network, same plan design, same prescription formulary, same deductibles and out-of-pocket maximums. What changes is who pays for it. While you were employed, your employer covered a substantial portion of the premium, often 70% to 85% of the cost for employee coverage. Under COBRA, you pay the full premium yourself, plus an administrative fee of up to 2%. That’s the reason COBRA often comes as a shock: a plan that cost you $200 per month suddenly costs $700 to $900 per month or more under COBRA because the full premium is exposed. For family coverage, the jump can be even more dramatic, with full premiums routinely running $1,800 to $2,400 per month.
Despite the cost, COBRA remains an important option in specific situations and deserves serious consideration whenever you face a coverage transition after employment changes. The key is understanding exactly what you’re paying for, how long it lasts, and what the alternatives actually cost before you commit.
Which Employers Are Required to Offer COBRA
Not every employer is required to offer COBRA. The law applies to private-sector employers with 20 or more employees. Smaller employers are exempt from federal COBRA requirements, though many states have “mini-COBRA” laws that extend similar protections to small group plans with fewer employees. Federal government employees have different continuation coverage options under a separate law. If your employer has fewer than 20 employees, check your state’s rules on continuation coverage availability before assuming you have no options.
The qualifying events that trigger COBRA eligibility for employees include voluntary resignation, involuntary termination (except for gross misconduct), and reduction in hours that causes loss of benefits eligibility. If you were fired for gross misconduct as defined by your employer’s plan, COBRA may not apply. For dependents, additional qualifying events include the covered employee becoming eligible for Medicare, divorce or legal separation from the covered employee, death of the covered employee, and a dependent child aging off the plan at 26. These events trigger COBRA eligibility for the affected individual even if the employee’s own coverage continues unchanged.
Under federal COBRA, your employer is required to notify the plan administrator within 30 days of a qualifying event, and the plan administrator must send you a COBRA election notice within 14 days of receiving that notification. You then have 60 days from either the date you lose coverage or the date the notice is sent, whichever is later, to decide whether to elect COBRA. That 60-day window is firm. Calendar it immediately when you receive the notice.
How Long COBRA Coverage Lasts
For employees and their dependents who lose coverage due to job loss or reduction in hours, COBRA continuation coverage lasts up to 18 months. For dependents who lose coverage due to events like divorce, death of the covered employee, or aging off at 26, coverage can last up to 36 months. A second qualifying event during an active 18-month COBRA period can extend coverage to 36 months for dependents who were already on COBRA when the second event occurred.
COBRA can end early if you stop paying premiums, if you become eligible for Medicare, if you become covered under another group health plan that doesn’t have a preexisting condition exclusion applicable to your situation, or if the employer sponsoring the plan terminates their group health coverage entirely. Paying premiums on time is critical: a single missed payment can end COBRA immediately once the grace period expires, and unlike missing an employer plan enrollment, there’s typically no way to reinstate COBRA coverage once it’s terminated for non-payment. Set up automatic payments if your insurer allows it.
Some states extend COBRA-like continuation coverage beyond the federal 18-month maximum. New York, for instance, has state continuation coverage that can extend beyond 36 months in some situations. California’s Cal-COBRA picks up where federal COBRA leaves off for small group plans. Understanding your state’s specific rules matters, particularly if you expect a longer gap before you can access other group coverage through a new employer or other means.
The Cost of COBRA: What You’re Actually Paying
The full premium including the employer’s contribution plus the 2% administrative fee is the maximum COBRA can charge. To understand what that means in dollars, you need to know the full premium for your plan, not just your employee share. When you receive your COBRA election notice, it will specify the monthly premium for each tier of coverage available: employee only, employee plus spouse, employee plus children, employee plus family. Read these numbers carefully before making any decisions.
For employer-sponsored plans at large companies, it’s common to see full premiums of $700 to $900 per month for individual coverage and $1,800 to $2,400 per month for family coverage. As an employee, you were paying perhaps $150 to $300 of the individual premium and $500 to $800 of the family premium. The jump to full COBRA costs is real and immediate. Budget for it before you elect COBRA, and compare the COBRA premium to what marketplace alternatives would cost after any applicable subsidies. People who skip this comparison often overpay by thousands of dollars over the course of a COBRA period.
There’s no way to reduce the COBRA premium through plan changes. Under COBRA, you continue the exact plan you were on at your employer. If you were on the premium plan, you can’t switch to a less expensive option under COBRA. You can only continue your current coverage at the full premium or decline COBRA and seek other coverage. This inflexibility is one of COBRA’s biggest limitations and one of the main reasons the marketplace comparison is so important.
The 60-Day Election Window and Retroactive Coverage
One of COBRA’s most strategically valuable features is how the 60-day election window works. When you lose employer coverage, you have 60 days to decide whether to elect COBRA. If you elect it, coverage is retroactive to the date your employer coverage ended. This means any claims you incur between your coverage end date and the date you elect COBRA are covered as if COBRA had been active from day one.
This creates a strategic option that some people use deliberately. If you leave your job and remain healthy for the 60-day decision period, you can elect a marketplace plan instead and save money on premiums going forward. If a significant medical claim occurs during that 60-day window, you can elect COBRA retroactively, pay all the back premiums at once, and have the claim covered. This works as long as you can afford to pay several months of back premiums if needed, and as long as you’re making a conscious, informed decision rather than just procrastinating.
The trade-off is real: you’re essentially self-insuring for 60 days against the risk of a major claim. For someone with known health conditions, scheduled procedures, or ongoing treatment, this strategy carries too much risk. For a healthy 32-year-old between jobs, it might be a reasonable calculated decision. Understand the bet before you make it.
When COBRA Makes Sense
Despite its cost, COBRA is the right choice in certain situations. If you have ongoing medical treatment with specific providers who are in your employer plan’s network but may not be in marketplace networks in your area, continuity of care is a genuine reason to pay the COBRA premium for at least a period of time. Changing networks mid-treatment can disrupt care with specialists, require re-authorization of treatments, and create gaps in prescription access. For someone undergoing cancer treatment or managing a complex chronic condition with an established care team, network disruption has real clinical consequences, not just financial ones.
COBRA also makes sense as a bridge when you expect new employer coverage to begin within a few months. If you have a job offer with a start date and know your new employer’s coverage begins on the first of the month after you start, paying one or two months of COBRA to avoid a marketplace enrollment and then immediate disenrollment may be simpler than the alternative. The administrative hassle of enrolling in a marketplace plan for a month or two and then transitioning to a new employer plan is real, and in that narrow scenario COBRA’s simplicity can justify the cost.
COBRA also makes sense if you have met or are close to meeting your current plan’s deductible or out-of-pocket maximum for the year. Switching to a new marketplace plan mid-year resets your deductible, meaning you’d be starting over on cost-sharing for the remainder of the year. If you’ve already paid $3,000 toward a $4,000 deductible and have planned procedures in the next few months, staying on COBRA to benefit from your already-met cost-sharing makes financial sense even at the higher premium.
COBRA vs. Marketplace Coverage: The Real Comparison
The decision between COBRA and marketplace coverage primarily comes down to cost, network, and timeline. Marketplace coverage after a qualifying event is often substantially less expensive than COBRA, particularly if your income qualifies for premium tax credits. An individual earning $40,000 per year might qualify for subsidies that bring a marketplace Silver plan premium down to $150 to $250 per month, compared to $800 or more for COBRA. Over an 18-month COBRA period, that’s a difference of $9,000 to $12,000. That’s real money.
But marketplace plans in some areas have narrower networks than large employer plans. If your employer plan offered a broad PPO with nationwide coverage and the available marketplace plans in your area are narrow HMOs, the network trade-off might justify a higher COBRA premium if you have established specialist relationships or anticipated care needs that depend on broad provider access. Check specific provider participation in both options before deciding. It’s not enough to know what tier of plan COBRA is versus a marketplace plan. You need to know whether your actual doctors are in-network on the specific marketplace plans available to you.
If your income is expected to be low for the year, Medicaid eligibility may make the COBRA vs. marketplace debate moot entirely. Apply through the marketplace and let the system route you to the most appropriate and affordable coverage based on your actual current circumstances. You might qualify for Medicaid at no premium cost. Acting within your 60-day window gives you time to do this comparison properly rather than defaulting to COBRA out of inertia or because the benefits administrator mentioned it first.
State Continuation Coverage for Small Employers
If your employer has fewer than 20 employees and isn’t subject to federal COBRA, your state may offer its own continuation coverage protections. These state mini-COBRA laws vary significantly. Some states require coverage continuation for groups as small as two employees. The required continuation period varies from three to 36 months by state. Premium rules also vary, though most state mini-COBRA laws allow the same structure as federal COBRA, meaning you pay the full premium plus an administrative fee.
If you’re leaving a small employer, don’t assume you have no continuation rights. Check your state’s insurance department website or contact a broker who knows your state’s rules. Some states with strong consumer protections offer continuation coverage that approaches the breadth of federal COBRA. Others offer minimal protection. Knowing what’s available gives you more options than assuming nothing exists.
Practical Steps When COBRA Arrives
When you receive your COBRA election notice, do these things in order. First, note the election deadline date, which is 60 days from the date on the notice. Put it in your calendar. Second, find the full monthly premium for each tier of coverage available to you. Third, log into HealthCare.gov or your state marketplace and run a subsidy estimate based on your expected income for the year. Fourth, compare the after-subsidy marketplace premium and available plan networks against your COBRA premium and current network. Fifth, if you’re in active treatment or have scheduled care in the next few months, call the relevant providers and ask if they’re in-network on specific marketplace plans you’re considering.
With that information, you can make an informed decision rather than an anxious one. COBRA is a legal right worth understanding, and marketplace coverage is often dramatically cheaper after subsidies. The correct answer is different for every person depending on their income, health status, location, and current care needs. Don’t let the clock run out without running the comparison.
