How do COBRA benefits work after leaving a job?

If you're leaving a job-whether by choice, layoff, or termination-you may be wondering what happens to your health insurance. The answer for most employees of companies with 20 or more workers is COBRA, short for the Consolidated Omnibus Budget Reconciliation Act. It lets you keep your employer-sponsored health plan for a limited time after you separate, but the catch is you'll pay the full premium yourself-plus a small administrative fee.

COBRA isn't a new plan or a government program. It's a continuation of the exact same coverage you had while employed. That means your doctors, networks, deductibles, and out-of-pocket maximums stay the same. However, unlike when you were employed and your employer subsidized the premium, under COBRA you’re responsible for the entire cost-typically 102% of the group rate. This can be expensive, often $500-$800 per month for individual coverage and well over $1,500 for family plans.

Who is Eligible for COBRA?

To qualify, your employer must have had at least 20 employees on more than half of its working days in the prior calendar year. You as an employee (or your covered dependents) must have been enrolled in the group health plan on the day before the qualifying event. Qualifying events include:

• Voluntary or involuntary job loss (except for gross misconduct)
• A reduction in work hours that makes you lose coverage
• Death of the covered employee
• Divorce or legal separation from the covered employee
• Loss of dependent child status under the plan

Each event has its own coverage duration: job loss or hour reduction gives you up to 18 months; death, divorce, or dependent status loss gives dependents up to 36 months.

How to Enroll in COBRA

Enrollment isn't automatic. Once you separate, your employer (or their benefits administrator) has up to 30 days to notify the plan. Then, the plan administrator has up to 14 days to send you a COBRA election notice. You have 60 days from the later of that notice or the date coverage would end to elect and pay for COBRA. If you miss that window, you lose the right to continue coverage. Here's the timeline:

1. Day 0: Qualifying event (last day of employment).
2. Within 30 days: Employer notifies the plan.
3. Within 14 days: Plan sends you the election notice.
4. Within 60 days: You must elect COBRA in writing.
5. Within 45 days of election: You must make your first premium payment (covering retroactive coverage).

Important: Once you elect, coverage is retroactive to the day after your employment ended, so you’re not left with a gap even if you decide later.

How Much Does COBRA Cost?

You pay the entire group premium-the portion your employer used to cover plus your own. That’s typically 102% of the total cost (the extra 2% covers administrative fees). For example, if your employer paid 80% of a $600 monthly premium, you paid $120. Under COBRA, you'd pay $612 (600 + 2% admin fee). That’s a 5x increase. For family coverage, it can easily exceed $2,000 per month. You cannot use pre-tax dollars or HSA contributions to pay for COBRA unless you have a special arrangement.

Alternatives to COBRA

Because COBRA is so expensive, many people consider other options. Here are the most common:

• Marketplace plan (ACA exchange): You can enroll within 60 days of losing job-based coverage. If your income qualifies, you may get premium tax credits that make plans far cheaper than COBRA.
• Spouse’s employer plan: Losing coverage triggers a special enrollment period, allowing you to join a spouse’s plan even outside open enrollment.
• Short-term health insurance: Offers limited coverage but may have exclusions and isn't ACA-compliant.
• Medicaid: If your income drops significantly, you may qualify immediately.

Pro tip: Always compare COBRA costs to marketplace plans. A divorced single mother earning $30,000 might pay $50/month for an ACA silver plan instead of $600/month for COBRA. But if you have high medical needs or use in-network specialists, sticking with your current plan via COBRA might be cheaper than hitting a new deductible.

What Happens When COBRA Ends?

You lose COBRA coverage after 18 months (or 36 months for dependents). Before it ends, you must secure new coverage-either through a new employer’s plan, a marketplace plan (you’ll qualify for a special enrollment period), or Medicare if you’re 65+. If you don’t, you risk a coverage gap, which can mean no insurance and potential late-enrollment penalties under Medicare or ACA plans if you wait too long.

One common mistake: assuming COBRA automatically ends at 18 months. It doesn’t. You’ll receive a notice before termination, but it’s your responsibility to transition. Mark your calendar 60 days before COBRA expires to shop for alternatives.

How Employee Benefits Systems Like WellthCare Can Help

While COBRA is a critical safety net, modern benefits systems are designing ways to reduce dependency on it. For example, the WellthCare ecosystem-a Health-to-Wealth operating system-offers $0-co-pay care, earned store dollars, and automatic pension contributions that are portable and not tied to continued employment. More importantly, WellthCare works alongside traditional health plans and doesn’t require COBRA to continue because the preventive care and rewards are accessible via the app regardless of employment status-as long as the employer sponsor keeps the benefit active. This kind of structural redesign can lower healthcare costs and make coverage more continuous, but COBRA remains the legal default for group plan continuation.

Final advice: You have 60 days to elect COBRA-but you don’t have to decide immediately. Use that time to compare costs, check network providers, and explore marketplace options. And remember: if you think you might need COBRA later (e.g., for a surgery), you can wait until the last day of the 60-day window to decide, and coverage will still be retroactive.
