Losing or leaving a job in the United States often means losing the health insurance that came with it, at a moment when you can least afford a gap in coverage. COBRA is the law that lets you keep that employer health plan for a period afterward, and understanding it helps you avoid being uninsured. This guide from The Finance Reveal explains what COBRA health insurance is, part of our Insurance section. This is general education about the US system, not insurance advice, and rules and eligibility vary.

What COBRA Is

COBRA is a US federal law that allows many employees, and their families, to continue their employer-sponsored group health insurance for a limited time after they would otherwise lose it. The name comes from the legislation that created it, and in everyday use, COBRA refers to the right to keep your existing workplace health coverage temporarily after a qualifying event such as leaving a job. Crucially, you keep the same plan you already had, with the same benefits and network, rather than having to find new coverage immediately.

The trade-off is cost. While employed, your employer typically pays a large share of your health insurance premium, with you covering the rest through payroll. Under COBRA, you generally must pay the full premium yourself, both your old share and the employer’s, often plus a small administrative fee. That means COBRA coverage usually costs substantially more out of pocket than you paid as an employee, even though the plan itself is unchanged, a reality that fits the wider health-cost picture our guide to health insurance terms explains.

How It Works

COBRA applies in specific situations and for limited periods. The table below summarizes the essentials.

Qualifying events commonly include leaving a job, whether you quit or are laid off, having your hours reduced below the coverage threshold, and certain family events. When a qualifying event occurs, you are typically notified of your right to elect COBRA and given a window to decide. If you elect it, your coverage continues, often for up to 18 months, though certain circumstances can extend that period. You pay the premiums to continue the plan, and if you stop paying, the coverage ends. The specific rules, eligibility, and durations depend on the situation and the size of the employer, so it is important to review the notice you receive and the details of your plan.

Deciding Whether to Use It

COBRA is valuable because it prevents a gap in coverage and lets you keep doctors and benefits you know, which matters especially if you are mid-treatment or have ongoing medical needs. However, because it is often expensive, it is worth comparing it with alternatives before electing it. Depending on your situation, options such as coverage through a spouse’s plan, a marketplace or exchange plan, or other programs may cost less, and losing job-based coverage is typically a qualifying event that lets you enroll in those alternatives outside the usual windows.

A practical approach is to weigh the cost of COBRA against these alternatives while considering continuity of care and how long you expect to need coverage. COBRA can be ideal as a bridge for a short gap, such as between jobs, or when keeping your exact plan is important, while a marketplace plan might be more economical for a longer stretch. Because you usually have a limited window to decide and coverage can be applied retroactively to the date you lost your job in some cases, do not ignore the notice. Understanding COBRA ensures that losing a job does not automatically mean losing health coverage when you need it most.

Frequently Asked Questions

What is COBRA health insurance?

COBRA is a US federal law that lets many employees and their families keep their employer-sponsored group health plan for a limited time after they would otherwise lose it, such as after leaving a job. You keep the same plan, benefits, and network, but you generally pay the full premium yourself, often plus a small fee, which makes it more expensive than what you paid as an employee.

Why is COBRA so expensive?

While you were employed, your employer typically paid a large portion of your health insurance premium. Under COBRA, you usually pay the entire premium yourself, your former share plus the part the employer used to cover, and often a small administrative fee. The plan is unchanged, but because you now shoulder the full cost, COBRA generally costs substantially more out of pocket than your employee contribution did.

How long does COBRA coverage last?

COBRA continuation coverage typically lasts for a limited period, commonly up to 18 months, though certain circumstances can extend it. The exact duration depends on the qualifying event and other factors. Coverage continues as long as you pay the premiums; if you stop paying, it ends. Because it is temporary, many people use COBRA as a bridge until they secure other coverage.

Is COBRA my only option after leaving a job?

No. COBRA is one option, but losing job-based coverage is usually a qualifying event that lets you enroll in alternatives outside the normal windows, such as a plan through a spouse’s employer, a marketplace or exchange plan, or other programs you may be eligible for. Because these can cost less than COBRA, it is worth comparing options on both price and continuity of care before deciding.

The Bottom Line

COBRA is a US federal law that lets many employees and their families keep their employer-sponsored health insurance for a limited time after a qualifying event such as leaving a job, being laid off, or having hours reduced. Its big advantage is continuity: you keep the exact same plan, benefits, and network rather than scrambling for new coverage, which is especially valuable if you are mid-treatment or have ongoing needs. The catch is cost, because you generally pay the full premium yourself, both your old share and the portion your employer used to cover, often plus a small fee, making COBRA significantly more expensive than what you paid as an employee. Coverage typically lasts up to 18 months, continues only while you pay, and applies after you receive a notice and elect it within a set window. Because it can be pricey, compare COBRA with alternatives like a spouse’s plan or a marketplace plan, since losing job coverage usually lets you enroll in those outside the normal periods and they may cost less. COBRA works best as a bridge for a short gap or when keeping your specific plan matters. Either way, do not ignore the election notice, since acting in time keeps you from being uninsured when you need coverage most.
