COBRA insurance explained

When you leave a job, you lose health insurance—unless you understand COBRA. This federal law allows you to keep your employer's health plan for a limited time after job loss, retirement, or a change in family status. But COBRA is expensive, temporary, and often misunderstood. Most people don't know they have this option, and those who do often don't understand how much it costs or whether it's actually worth it.

Quick definition: COBRA is the Consolidated Omnibus Budget Reconciliation Act, a federal law that requires employers with 20+ employees to offer continuation health coverage to departing workers and their families for up to 18 months. You pay the full cost—usually 100% of the premium plus a 2% administrative fee.

COBRA is not a free lunch. It's a legally mandated option to avoid a gap in coverage while you transition to another plan. It matters because health insurance gaps create two real risks: a medical emergency without coverage, and the inability to get affordable coverage later due to pre-existing conditions (a risk now lower due to the Affordable Care Act, but still real in some scenarios).

This article teaches you what COBRA actually is, when you qualify, how much it costs, and whether it makes sense for your situation.

Key takeaways​

  • COBRA lets you keep your employer plan for up to 18 months after job loss. You pay 100% of the premium plus 2%, so it's often more expensive than staying employed, but familiar and continuous.
  • Qualifying events include job loss, voluntary resignation, reduced hours, divorce, death of an employee, and loss of dependent status. Not every employment change triggers COBRA rights.
  • COBRA is expensive because you pay the full premium. What your employer was subsidizing becomes your cost. A plan that cost you <$300/month as an employee might cost you <$800/month under COBRA.
  • You must elect COBRA within 60 days. Miss the deadline and you lose the right to it for the rest of your life—you cannot go back and claim it later.
  • COBRA coverage is temporary. It lasts 18–36 months depending on your situation. Plan your next coverage step before COBRA ends to avoid a gap.

What COBRA actually is​

COBRA is a federal law passed in 1985 that requires larger employers to offer continuation of health coverage. It's not a new insurance plan or a government program. It's a rule that forces your employer's existing health insurance to keep you as a member, at your cost instead of their cost, for a limited time.

When you're employed, your employer pays part of your health insurance premium (often 50–75%) and you pay the rest through payroll deductions. Under COBRA, you pay the entire premium plus a 2% administrative fee. That's why it's expensive.

The word "option" is key. COBRA doesn't automatically happen. Your former employer must offer it if they employ 20 or more people and you qualify. You must affirmatively elect it within 60 days or you lose the right to it.

This is important: if you don't elect COBRA on time, you cannot change your mind later. Unlike health insurance marketplace plans that have open enrollment, COBRA is a one-time election window. Miss it and the option is gone forever.

Who qualifies for COBRA​

Not every job separation qualifies you for COBRA. The law lists specific "qualifying events" that give you the right to continue coverage. Your employer should provide written notice of these rights, usually in your benefits handbook or as a separate document when you leave.

The main qualifying events are:

Job loss or termination (for any reason except gross misconduct). If you're laid off, fired (except for gross misconduct), or let go in a reduction, you qualify. Note the exception: if you're terminated for gross misconduct (theft, violence, repeated insubordination leading to firing), your employer may be able to deny COBRA.

Voluntary resignation. If you quit, you still qualify for COBRA. This is surprising to many people—they assume COBRA only applies to involuntary job loss. Not true.

Reduction in hours. If you go from full-time to part-time and lose insurance eligibility as a result, you qualify. If the employer simply reduces your hours but you remain covered, no COBRA trigger.

Divorce or legal separation. Both the employee and the spouse (through the employee's plan) can elect COBRA if the divorce causes loss of coverage.

Death of the employee. The surviving spouse and dependent children can elect COBRA.

Loss of dependent status. If a child ages out of the plan or no longer meets the definition of a dependent, that child can elect COBRA.

Medicare eligibility. If the employee becomes eligible for Medicare, the employee and dependents can elect COBRA.

The key phrase: "loss of coverage as a result of the qualifying event." If the qualifying event doesn't cause you to lose your coverage, COBRA doesn't apply. For example, if you retire at 62 but your employer keeps you on the health plan, no COBRA right. But if you retire and the employer removes you, COBRA applies.

How long COBRA lasts​

COBRA continuation is not permanent. The maximum coverage period depends on the qualifying event.

For the employee or a dependent due to job loss, reduction in hours, or death: 18 months. This is the most common scenario. If you're laid off, you get 18 months of COBRA coverage.

For a spouse or dependent due to divorce or legal separation: 36 months. This is much longer and critical for non-working spouses or dependent children without alternative coverage.

For Medicare eligibility: The time period that would otherwise apply, minus any time used for another qualifying event.

For loss of dependent status: 36 months from the date the dependent loses coverage.

The clock starts the day you lose coverage, not the day you elect COBRA. So if you're terminated on June 15 and elect COBRA on July 1, your 18 months starts June 15, not July 1.

This means you can't extend COBRA by delaying your election. You have 60 days from the loss of coverage to elect, but the coverage period is calculated from the loss date, not the election date.

The cost of COBRA​

This is the shock most people face: COBRA is expensive. Here's the real math.

Your employer probably subsidized a large portion of your health insurance. A typical employer covers 50–75% of the premium. When you leave, you lose that subsidy. COBRA requires you to pay the full premium—every penny your employer was paying, plus every penny you were already paying.

Example: a plan that cost you <$200/month as an employee (employer paid <$400) now costs you <$600/month under COBRA. Add the 2% administrative fee and you're at <$612.

For a family plan, the numbers are worse. A family plan might cost the employer <$800/month and you <$200/month. Under COBRA, you're paying <$816/month (<$800 plus 2%).

Multiply that by 18 months and the total cost of COBRA for someone on a mid-range plan is <$10,000 to <$15,000. For a family, it can exceed <$20,000.

That's why COBRA is a bridge option, not a long-term solution. It's meant to cover the gap between jobs, not to be your ongoing health insurance.

There are rare cases where an employer continues to subsidize COBRA (severance packages sometimes include COBRA subsidy), but this is increasingly uncommon. Assume you're paying the full cost.

When COBRA makes sense​

Given the cost, when is COBRA the right choice?

You have continuing medical treatment. If you're mid-cancer treatment, managing a chronic condition, or taking medications that require prior authorization, switching insurance plans mid-treatment is dangerous. COBRA lets you finish your current treatment plan with the same insurance and doctors without network disruptions.

You have a short employment gap (less than 3 months). If you're between jobs and confident you'll have new insurance quickly, COBRA bridges the gap. Three months of COBRA (<$1,200 to <$1,800 for an individual) might be cheaper than paying a penalty or having an uninsured gap.

New employer insurance has a waiting period. Some employers have 30–90 day waiting periods before coverage starts. COBRA bridges this gap.

You have dependents without alternative coverage. If you're supporting a spouse or children and they would otherwise be uninsured, COBRA might be your cheapest option temporarily.

You're on a spouse's plan and the spouse dies. Losing access to a spouse's plan mid-year is traumatic. COBRA gives the surviving spouse and children 36 months to find alternative coverage, which is usually more than enough time.

When COBRA does NOT make sense​

You're young and healthy. If you're 25, have no chronic conditions, and are between jobs, the cost of COBRA is hard to justify. A short-term health insurance plan or a marketplace plan with premium tax credits might be 50–70% cheaper.

You have marketplace insurance available. If you've lost income due to job loss, you likely qualify for substantial premium subsidies on a marketplace plan. A marketplace plan with subsidies might cost <$100/month versus <$600 for COBRA.

Your new employer's coverage starts soon. If you have a new job starting in 4 weeks, COBRA is overkill. Marketplace insurance or a short-term plan covers the gap more cheaply.

You can be on a family member's plan. If a spouse, parent, or partner has employer coverage and can add you, that's usually cheaper than COBRA and often has better cost-sharing.

The COBRA election process​

You must actively choose COBRA; it doesn't happen automatically.

Step 1: Receive notice. Your employer (or their benefits administrator) must provide written notice of your COBRA rights within 14 days of your employment ending. This notice must include the coverage effective date, the cost, the election deadline (60 days), and the steps to elect.

Step 2: Decide within 60 days. You have 60 days from the date you lose coverage to decide. This is a firm deadline. After 60 days, your right to COBRA is gone forever.

Step 3: Make the election. Contact your employer's benefits administrator (usually a benefits company like Aetna, Cigna, or UnitedHealth). You'll fill out a form and provide payment information. Your coverage becomes effective on the first day after your employment ends (or the day you would have lost coverage).

Step 4: Pay premiums. You must pay the first month's premium within 45 days of electing COBRA. After that, you pay monthly to keep coverage active.

If you miss the 45-day payment deadline, coverage will be terminated and cannot be reinstated. This is different from regular insurance; there's no grace period.

Alternatives to COBRA​

Before paying <$600–<$800/month for COBRA, understand your other options.

Marketplace insurance (ACA). If you've lost income, you likely qualify for substantial subsidies. A family of four making <$50,000/year might pay <$0–<$200/month for marketplace insurance. You must enroll within 60 days of the qualifying event (job loss) or wait until open enrollment.

Short-term health insurance. Short-term plans are cheap (<$100–<$300/month) but have limited coverage and no pre-existing condition protections. Use them only as emergency bridges for 3–6 months, not long-term.

Medicaid. If you lose income, you might qualify for Medicaid. The threshold varies by state, but most cover individuals under <$20,000/year of income.

Spouse's plan. If your spouse has employer coverage, adding you might be cheaper than COBRA and usually happens during the next open enrollment or immediately after a qualifying event (marriage, job loss).

Real-world scenarios​

Scenario 1: Mid-treatment, no choice.

Rachel has late-stage breast cancer. She's on chemotherapy with her employer's health plan. She's laid off. Her oncologist's treatment plan has 4 months remaining. She elects COBRA immediately. Yes, it costs <$2,000 for the 4 months. But switching insurance mid-treatment is risky—new insurance might not authorize the remaining chemo, or might require a different protocol. COBRA's cost is worth the continuity.

Scenario 2: Healthy, between jobs.

Marcus is 32, healthy, no prescriptions. He's laid off. He has a new job offer starting in 6 weeks, but that company's health insurance starts on day 60. He's tempted to elect COBRA for the 6-week gap. COBRA would cost <$900 for the 6 weeks. Instead, he buys a short-term plan for <$150 and saves <$750. He's self-insured during those 6 weeks because he's healthy.

Scenario 3: Subsidies available.

Jennifer has a family of four, family income <$55,000/year. She loses her job. COBRA for a family would cost <$1,500/month. She enrolls in a marketplace plan instead. With tax credits, she pays <$250/month for the same level of coverage. She saves <$15,000 over 18 months.

Scenario 4: Aging into Medicare.

Robert is 65 and loses his job due to a company closure. He's eligible for Medicare. COBRA would cost <$700/month for 18 months. But he enrolls in Medicare immediately (he can enroll anytime after 65). He pays <$180/month in Medicare premiums. He saves <$9,360 over 18 months by not using COBRA.

Common mistakes​

  1. Thinking COBRA is automatic. It is not. You must affirmatively elect it within 60 days. Many people lose their right to COBRA by not making the election on time.

  2. Waiting to see if you need coverage before electing. This is dangerous. By the time an emergency happens, it's too late to elect COBRA. You have 60 days from loss of coverage, not 60 days from your first bill. Elect COBRA early and cancel if you don't need it.

  3. Not comparing COBRA to marketplace insurance. COBRA is often much more expensive than a subsidized marketplace plan. Always run the numbers on both.

  4. Forgetting that COBRA is temporary. Assume 18 months is your maximum. At month 17, start researching your next coverage option. Don't be caught with no insurance when COBRA ends.

  5. Thinking you can negotiate COBRA prices. You cannot. COBRA is the full premium set by your employer's insurance plan. There's no discount or wiggle room.

  6. Not paying premiums on time. If you elect COBRA but miss a monthly premium, you're in a gap with no coverage. Set up automatic payments.

FAQ​

Q: If I was laid off, do I automatically get COBRA?

A: No. You have the right to elect COBRA, but you must take action within 60 days. Your employer must give you written notice, but you must choose it yourself.

Q: Can I elect COBRA after 60 days?

A: No. The 60-day window is firm. After 60 days, your right to COBRA is gone forever and cannot be restored.

Q: What happens to COBRA if my employer goes bankrupt?

A: That's complex. If the employer goes bankrupt before you elect COBRA, the right might be lost. If you've already elected COBRA and the employer bankrupts, the plan administrator is usually still obligated to provide coverage. This is a rare scenario where you should consult a benefits attorney.

Q: Do I have to elect COBRA if offered?

A: No. You can decline COBRA and choose marketplace insurance or another option. But once you decline, you cannot later choose COBRA (unless a new qualifying event occurs).

Q: Can COBRA be extended beyond 18 months?

A: In very rare circumstances, yes. If you become disabled while on COBRA, you might qualify for an 11-month extension (to 29 months). This must be claimed before the original 18 months end. Otherwise, no extensions.

Q: Is COBRA required if I volunteer to resign?

A: Yes, voluntary resignation is a qualifying event. You still get COBRA rights even though you quit.

Q: What if I retire—do I get COBRA?

A: Only if retirement causes loss of coverage. If your employer keeps you on the plan after retirement, no COBRA. If retirement means you're removed from the plan, COBRA applies.

Summary​

COBRA is a federally mandated right to continue your employer's health coverage after a qualifying event. It's expensive because you pay 100% of the premium, but it's valuable when you need continuity of care. You must elect COBRA within 60 days of losing coverage, and coverage lasts 18–36 months depending on your situation. COBRA makes sense if you're mid-medical treatment or have a short employment gap; it rarely makes sense if you're young, healthy, and have access to subsidized marketplace insurance. Compare COBRA to marketplace plans before committing—subsidized marketplace coverage often costs 50–70% less.
