COBRA Health Insurance: How It Works and What It Costs

COBRA—the Consolidated Omnibus Budget Reconciliation Act—allows workers who lose employer-sponsored health coverage to keep their company’s health plan for a limited time by paying the full premium themselves. How does COBRA health insurance work: the employer stops subsidizing the plan, and the ex-employee pays both the employer and employee share of the premium, plus a small administrative fee, for 18 to 36 months depending on the triggering event.

Who is Eligible for COBRA

COBRA applies to employers with 20 or more employees. An employee becomes a COBRA beneficiary (and their family members become qualified beneficiaries) when they experience a “qualifying event”—a change in status that would normally cause them to lose health coverage.

The most common qualifying event is involuntary termination: the employee is fired or laid off for reasons other than gross misconduct. A voluntary resignation also triggers COBRA, though some employees do not realize they have the option. A reduction in work hours (so the employee no longer meets the employer’s eligibility threshold) also qualifies.

Death of the covered employee allows the surviving spouse and dependent children to elect COBRA. A divorce or legal separation ends spousal coverage; the ex-spouse can elect COBRA independently. An adult child aging off the plan (usually at 26 under the Affordable Care Act) qualifies. A retiree becoming eligible for Medicare is another triggering event, though a retiree losing employer coverage before Medicare eligibility can also elect COBRA.

Gross misconduct is the only exception: an employee fired for serious rule violations (theft, violence, fraud) may be denied COBRA, though this exclusion is interpreted narrowly.

The Coverage Window: 18, 29, or 36 Months

COBRA coverage is temporary. The length depends on the triggering event.

18 months is the standard for job loss (voluntary or involuntary termination, reduction in hours). This period can extend to 29 months if the employee becomes disabled (within 60 days of losing coverage) and notifies the employer. During months 19–29, the premium can increase 50% above the 102% rate, creating a strong incentive to find other coverage.

36 months applies to divorce, death, or loss of dependent status. The ex-spouse or survivor can remain on the plan for three years.

These periods are measured from the date coverage would have ended, not from the date of the event. If an employee is terminated on June 15, coverage ends on June 30, and the 18-month window runs through December 30 of the following year.

Why COBRA Premiums Are So High

The single biggest shock is the cost. During employment, the employer typically subsidizes 70–80% of the premium. The employee pays the remaining 20–30%. Upon losing the job, the ex-employee must pay the full 100% of the premium—plus 2%—because there is no employer to absorb its share.

A mid-size family plan might cost an employer $18,000 per year. The employee paid $4,000 out of pocket. Under COBRA, the full $18,360 ($18,000 × 1.02) becomes due. For many workers, this is unaffordable. A family earning $60,000 annually cannot easily absorb an extra $18,000 per year in health premiums, especially during a period of job loss and reduced income.

There is no relief. An ex-employer cannot choose to waive or reduce the COBRA premium; COBRA law sets it at 102% of the “applicable premium”—the rate the employer charges for similar active employees. A federal tax-credit called the COBRA subsidy has been offered during recessions (2009, 2020) to reduce the premium, but it is temporary and must be appropriated by Congress.

Timing: Election and Payment

An employer must notify a separating employee of their COBRA rights within 14 days of the qualifying event. The employee then has 60 days to decide whether to elect COBRA coverage. If they do not elect within 60 days, the right lapses.

The first premium payment is usually due 45 days after the election is made. If the employee misses a payment, most plans allow a 30-day grace period before coverage terminates. After that, there is no second chance to enroll in that COBRA period.

Employers sometimes drag out notification, and employees sometimes miss the 60-day window. Both mistakes are costly.

Alternatives to COBRA

For many workers, COBRA is not the only option. The Affordable Care Act created a marketplace for individual health insurance. An ex-employee can shop for a plan on healthcare.gov or a state exchange. Depending on income, they may qualify for a tax-credit that subsidizes the premium. For workers with very low income, Medicaid is available in most states.

A spouse might stay on a spouse’s employer plan if they are employed. A young, healthy person might choose to go uninsured for a few months while job-hunting, though the current penalty for being uninsured is zero.

For some, a low-cost catastrophic plan from the marketplace is cheaper than COBRA. For others—especially those with expensive ongoing treatments—COBRA’s access to the same doctors and network is worth the cost.

Special Cases: Disability and the Medicare Trap

If an employee becomes disabled within 60 days of losing coverage, they can extend COBRA from 18 to 29 months. The employee must notify the plan administrator and the employer within 60 days of both the qualifying event and the disability determination. This extension is valuable for someone on expensive medications or ongoing treatment.

A separate issue: if a COBRA beneficiary reaches Medicare eligibility (usually 65), COBRA coverage ends immediately. There is no 36-month window for a retiree already on Medicare. This can create awkward timing if a retiree reaches 65 before their COBRA window closes.
