COBRA Insurance: How Continuation Coverage Works and What It Costs

The Full Cost of Your Employer Plan—Finally Visible

The average employer-sponsored family health plan costs $23,968 per year in 2023, according to the Kaiser Family Foundation annual survey. The average employee pays $6,575 of that—the employer quietly absorbs the remaining $17,393. Most workers never see the full number until they lose their job and receive a COBRA notice stating that continuation coverage will cost them roughly $2,000 per month. The sticker shock is real, but so is the coverage: COBRA provides access to the exact same health plan, with identical networks and benefits, as the group coverage the employee just lost.

The price is the problem. Nothing else is.

What COBRA Is and Where It Applies

The Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA) requires most private-sector employers with 20 or more employees to offer former employees and certain dependents the option to continue group health coverage for a limited period after a qualifying event. Federal employees are covered by a similar law (the Federal Employees Health Benefits program has comparable continuation provisions). Some states have "mini-COBRA" laws that extend similar rights to employees of smaller employers—California, New York, and Illinois, among others, require continuation coverage even for employers with fewer than 20 employees.

Qualifying Events and Who Is Eligible

COBRA coverage is triggered by specific qualifying events that cause a loss of group health plan coverage. The eligible individual and the nature of the qualifying event determine the maximum coverage period:

Termination for gross misconduct disqualifies the employee from COBRA—though the employee's dependents may still be eligible. "Gross misconduct" is not defined in COBRA itself and has been the subject of substantial litigation; employers should exercise caution before denying coverage on this basis.

The 102% Premium Cap

COBRA allows plan sponsors to charge qualified beneficiaries up to 102% of the total group health plan premium—the employee's share, the employer's share, and a 2% administrative fee. This is the source of the dramatic cost increase: the employee, who previously paid perhaps 28% of the total premium, now pays 102% of the full amount. For a family plan, this commonly exceeds $2,000 per month.

Some employers voluntarily subsidize COBRA premiums as part of severance arrangements, particularly for executive-level departures. Federal legislation (such as the ARPA COBRA subsidy that ran April–September 2021) has at times provided temporary government-paid COBRA subsidies for specific groups, but no permanent federal subsidy exists as of 2024.

Enrollment Deadlines: The 60-Day Election Window

After a qualifying event, the plan administrator has 30 days to notify the plan; the plan then has 14 days to send a COBRA election notice to qualified beneficiaries. Beneficiaries have 60 days from the later of the coverage loss date or the notice date to elect COBRA coverage. Missing this 60-day window permanently forfeits COBRA rights for that qualifying event—there is no late enrollment penalty structure as there is with Medicare; it is simply unavailable.

After electing COBRA, beneficiaries have 45 days from the election date to make the first premium payment, which covers all months retroactively to the qualifying event. A person who waits until day 59 to elect and uses the full 45-day payment window may go more than three months without paying a premium while technically maintaining coverage—a strategy sometimes used when someone is healthy and waiting to see whether they incur medical expenses before deciding whether to pay.

Grace Periods and Termination of Coverage

After the initial 45-day payment period, subsequent monthly premiums have a 30-day grace period. Coverage cannot be terminated for non-payment until the grace period expires without payment. However, if coverage is terminated for non-payment, it cannot be reinstated—the beneficiary loses both COBRA rights and the ability to obtain a special enrollment period based on loss of COBRA coverage (though losing COBRA coverage due to exhaustion of the maximum period does trigger a special enrollment period on the ACA marketplace).

COBRA vs ACA Marketplace: A Cost Comparison

For many COBRA-eligible individuals, an ACA marketplace plan may offer comparable coverage at significantly lower net cost, particularly for those whose income qualifies for premium tax credits. Key comparison points:

• ACA marketplace plans must cover the 10 essential health benefits; COBRA continues whatever the employer plan covered (which also likely covers all 10)
• Premium tax credits are available based on income for ACA plans; no equivalent subsidy exists for COBRA
• Network and drug formulary will differ on a new marketplace plan vs the former employer plan
• ACA enrollment can begin immediately upon loss of coverage—the special enrollment period lasts 60 days from the qualifying event
• A person who elects COBRA can later switch to a marketplace plan when COBRA is exhausted, triggering another 60-day special enrollment period

For someone with a specific physician, ongoing treatment, or prescription that is in-network under the employer plan, COBRA's identical network may justify the premium cost despite cheaper marketplace options being available. For a healthy individual with no current ongoing care, a marketplace plan with subsidies is frequently the economical choice.
