Losing your job is stressful enough without the added panic of losing health insurance. That’s where COBRA comes in — but the sticker shock catches most people off guard. What is COBRA insurance, and is it worth the cost? The Consolidated Omnibus Budget Reconciliation Act of 1985 gives eligible employees and their families the right to continue their employer-sponsored health coverage after a qualifying event like job loss. The coverage is identical to what you had while employed, but you now pay the full premium — employer share included — plus a 2% administrative fee. For many, that means monthly costs of $600 to $2,000 or more. This guide explains who qualifies, what it costs, and when a cheaper alternative makes more sense. For a broader understanding of healthcare costs, see our healthcare costs guide.
How COBRA Insurance Works
COBRA isn’t a separate insurance plan — it’s a federal law that requires employers with 20 or more employees to offer departing workers the option to continue their existing group health coverage for a limited time. The coverage, network, benefits, deductible, and copays remain exactly the same. What changes is who pays: while employed, your employer typically covers 70-80% of the premium. Under COBRA, you’re responsible for 100% of the premium plus up to a 2% administrative surcharge.
The law applies to private-sector employers and state and local governments with 20 or more employees. Federal employees have a similar program under the Federal Employees Health Benefits (FEHB) program. Many states have “mini-COBRA” laws that extend similar protections to employees of smaller companies — the Department of Labor maintains guidance on federal COBRA, while state insurance departments cover mini-COBRA rules.
COBRA applies to group health plans including medical, dental, and vision coverage. It does not apply to life insurance, disability insurance, or plans maintained by the federal government or churches. Health FSAs are technically eligible for COBRA continuation, but continuing one is rarely cost-effective.
Who Qualifies for COBRA?
COBRA eligibility requires a “qualifying event” — a specific life change that would otherwise cause you to lose group health coverage. The most common qualifying events include voluntary or involuntary job loss (except for gross misconduct), reduction in work hours that affects benefit eligibility, divorce or legal separation from the covered employee, the covered employee’s death, and a dependent child aging out of the plan (typically at age 26).
For the employee (called the “qualified beneficiary”), job loss and reduced hours trigger up to 18 months of COBRA coverage. For spouses and dependent children, certain events — divorce, death of the employee, or the employee becoming eligible for Medicare — can trigger up to 36 months. A second qualifying event during the initial 18-month period can extend coverage to 36 months for dependents. Disability determination by the Social Security Administration within the first 60 days of COBRA coverage extends the period to 29 months, though the premium increases to 150% of the plan cost during the extended months.
According to the Centers for Medicare and Medicaid Services (CMS), you must be notified of your COBRA rights within 14 days of the plan administrator learning about the qualifying event. You then have 60 days from the notification date (or the date coverage would end, whichever is later) to elect COBRA. Coverage is retroactive to the date of the qualifying event, so there’s no gap — but you’ll owe premiums for the entire period.
How Much Does COBRA Cost?
COBRA costs are based on the full premium your employer’s group plan charges — not just the portion you were paying as an employee. According to the Kaiser Family Foundation’s Employer Health Benefits Survey, the average annual premium for employer-sponsored health insurance in 2024 was approximately $8,951 for individual coverage and $25,572 for family coverage. Divide those by 12 and add the 2% COBRA surcharge:
- Individual COBRA: Approximately $760 per month
- Family COBRA: Approximately $2,175 per month
These are averages — your actual cost depends on your former employer’s plan. High-cost plans in expensive metropolitan areas can exceed $2,500 per month for family coverage. The premium must be paid in full and on time; COBRA has a 30-day grace period for monthly payments, but missing a payment can result in permanent loss of coverage with no reinstatement option.
For most people, COBRA represents a dramatic increase from what they were paying as employees. If you were contributing $200 per month toward your employer plan, suddenly owing $760 or more is a financial shock — especially when it coincides with job loss. This is why exploring alternatives before defaulting to COBRA is critical.
COBRA Enrollment Timeline
The COBRA enrollment process follows strict deadlines that cannot be extended:
- Employer notification: Your employer must notify the plan administrator within 30 days of the qualifying event
- Plan administrator notification: The plan administrator must send you a COBRA election notice within 14 days of receiving the employer’s notification
- Your election deadline: You have 60 days from the date of the notice (or the date coverage would otherwise end, whichever is later) to elect COBRA
- First payment: You have 45 days after electing COBRA to make your first premium payment (retroactive to the coverage start date)
- Ongoing payments: Monthly payments are due on the first of each month with a 30-day grace period
A strategic approach many people use: wait until near the end of the 60-day election period before deciding. If you incur significant medical expenses during that window, elect COBRA retroactively and the expenses are covered. If you stay healthy and find alternative coverage, you can decline COBRA and save the premiums. This isn’t gaming the system — it’s a legitimate use of the enrollment window.
Alternatives to COBRA
COBRA is not your only option, and for many people, it’s not the best one financially.
ACA Marketplace Plans
Losing employer coverage is a qualifying life event that triggers a 60-day Special Enrollment Period on the Health Insurance Marketplace. Marketplace plans may be significantly cheaper than COBRA, especially if your income during unemployment qualifies you for premium tax credits (subsidies). A family of four earning $60,000 could receive substantial monthly subsidies, potentially bringing premiums well below COBRA rates. The coverage may have different networks and deductibles, so compare carefully.
Spouse’s Employer Plan
Your loss of coverage is also a qualifying event for your spouse’s employer plan. If your spouse has access to employer-sponsored insurance, joining that plan may be the most cost-effective option, as the employer typically subsidizes a significant portion of the premium.
Medicaid
If your income drops significantly after job loss, you may qualify for Medicaid, which provides free or very low-cost coverage. Eligibility varies by state — in the 40 states that expanded Medicaid under the ACA, adults earning up to 138% of the federal poverty level qualify. You can apply at any time (Medicaid has no enrollment periods).
Short-Term Health Insurance
Short-term plans offer temporary coverage (up to 364 days in many states, renewable for up to 3 years) at lower premiums than COBRA. However, they typically don’t cover pre-existing conditions, may have benefit limits, and don’t count as minimum essential coverage under the ACA. They’re best suited for healthy individuals needing gap coverage while transitioning to a permanent plan.
When COBRA Makes Sense
Despite the high cost, COBRA is the right choice in several scenarios. If you’re in the middle of treatment for a serious condition with specific in-network providers, switching plans could disrupt care and cost you more in the long run. If you’ve already met a significant portion of your deductible or out-of-pocket maximum for the year, continuing on COBRA preserves that progress — switching to a new plan resets these accumulators.
COBRA also makes sense if you expect to have new employer coverage within a few months — it bridges the gap without the hassle of enrolling in a marketplace plan for a short period. And if you need coverage immediately with no application process or waiting periods, COBRA is automatic — you simply elect and pay.

Frequently Asked Questions
How long does COBRA coverage last?
The standard COBRA continuation period is 18 months for job loss or reduced hours. It can extend to 29 months if you receive a Social Security disability determination within the first 60 days. Spouses and dependents may qualify for up to 36 months following divorce, death of the employee, or the employee becoming Medicare-eligible.
Can I be denied COBRA coverage?
If you meet the eligibility requirements (covered under a qualifying group plan, experienced a qualifying event, and the employer has 20+ employees), your employer cannot deny COBRA. The only exception is termination for “gross misconduct” — a narrowly defined term that courts have interpreted to require intentional, serious wrongdoing. Standard layoffs, downsizing, performance-based termination, and voluntary resignations all qualify for COBRA.
Is COBRA retroactive?
Yes. COBRA coverage is retroactive to the date your employer coverage ended, regardless of when you elect it during the 60-day window. This means any medical expenses you incur during the gap between losing coverage and electing COBRA will be covered — as long as you elect and pay the retroactive premiums.
Can I switch from COBRA to a marketplace plan?
Yes. Exhausting COBRA coverage (reaching the end of your 18- or 36-month period) is a qualifying life event for the marketplace. You can also voluntarily drop COBRA and enroll in a marketplace plan during the annual Open Enrollment Period (November 1 through January 15). However, voluntarily dropping COBRA outside of Open Enrollment does not trigger a Special Enrollment Period on the marketplace.
What to Do Next
If you’re facing a COBRA decision, don’t panic — you have 60 days to decide, and that time is on your side. Start by getting the exact COBRA premium amount from your employer or plan administrator. Then compare that cost against marketplace plans at healthcare.gov (check your subsidy eligibility based on projected annual income), your spouse’s plan options, and Medicaid eligibility in your state. Factor in where you are in your current plan’s deductible year and any ongoing treatment needs. For most healthy people between jobs, a marketplace plan with subsidies will be significantly cheaper than COBRA. But for those mid-treatment or close to meeting their deductible, COBRA’s continuity can be worth the premium.
