How Does COBRA Insurance Work? Cost and Rules (2026)

COBRA lets you keep the exact same employer health plan you had — for a limited time — after you lose job-based coverage, but you must pay the full premium yourself instead of having an employer cover most of it. That is why COBRA feels so expensive: nothing about the coverage changes, but the whole bill shifts to you.

COBRA (the Consolidated Omnibus Budget Reconciliation Act) is a federal law that gives workers and their families a safety net when a job ends or hours are cut. It is valuable when you are mid-treatment or attached to your doctors — but it is often not the cheapest option. This guide explains how COBRA works, what it costs with a worked example, who qualifies, the deadlines that matter, and when a Marketplace plan beats it.

What is COBRA and how does it work?

COBRA is not an insurance company or a plan — it is a right. According to the U.S. Department of Labor, COBRA gives certain former employees, spouses, and dependent children the right to temporarily continue the group health coverage they had through an employer, at group rates, after that coverage would otherwise end.

Here is the mechanism in plain terms:

1. A “qualifying event” ends your coverage — for example, you quit, are laid off (for reasons other than gross misconduct), or your hours drop below the plan’s threshold.
2. The plan sends you an election notice explaining your right to continue coverage and what it will cost.
3. You elect COBRA within 60 days and pay the premium. Your coverage — same network, same deductible, same benefits — continues without interruption.

COBRA generally applies to private employers with 20 or more employees, plus state and local governments. Smaller employers are exempt from federal COBRA, though many states have “mini-COBRA” laws that extend similar rights to small-group plans.

How much does COBRA cost?

This is where COBRA surprises people. While you were employed, your employer likely paid 70–80% of your premium. Under COBRA, you pay 100% of the premium — the employer’s old share plus your share — plus an administrative fee of up to 2%, allowed under the law.

So the coverage costs exactly the same to provide; you simply see the full price for the first time.

COBRA cost: a worked dollar example

Suppose Jordan’s employer plan has a total premium of $650/month for single coverage. While employed, Jordan paid $150 and the employer paid $500.

Jordan’s out-of-pocket premium jumps from $150 to about $663 a month — more than four times higher — even though the plan is identical. Over an 18-month COBRA run, that is nearly $12,000. This sticker shock is exactly why it pays to compare COBRA against an ACA Marketplace plan before electing.

How long does COBRA last?

The maximum length depends on the qualifying event, per Department of Labor rules:

Coverage can end early if you stop paying the premium, the employer stops offering any group plan, or you become covered under another group plan or Medicare.

The deadlines that matter

COBRA runs on strict timelines. Miss them and you can lose the right entirely:

• 60 days to elect. After receiving your election notice (or the date coverage would end, whichever is later), you have 60 days to sign up.
• Retroactive coverage. If you elect, coverage is backdated to the day your old plan ended — so there is no gap. This lets you “wait and see”: you can decline at first and still elect within the window if you have a medical need.
• 45 days to pay. After electing, you have 45 days to make your first premium payment. It must cover the retroactive period.
• 30-day grace period. Subsequent monthly payments generally have a 30-day grace period.

COBRA vs. an ACA Marketplace plan

Losing job-based coverage is a “qualifying life event” that opens a Special Enrollment Period on the Marketplace — a 60-day window to buy an individual plan, separate from open enrollment. Per HealthCare.gov, a Marketplace plan is often more affordable than COBRA, especially because you may qualify for a premium tax credit that COBRA never offers.

When COBRA still makes sense:

• You are mid-treatment and cannot risk changing doctors, networks, or your deductible mid-year.
• You have already met most of your deductible or out-of-pocket maximum this year — starting over on a new plan would cost more.
• You only need coverage for a short gap before a new job’s plan begins.

When the Marketplace usually wins: you are healthy, your income qualifies you for subsidies, or you are early in the plan year with little spent toward your deductible. Because electing COBRA is retroactive, you can even compare both before committing.

Common mistakes and money-saving tips

• Electing COBRA without comparing. Always price a Marketplace plan first — the subsidy can cut your cost dramatically versus COBRA’s full premium.
• Missing the 60-day election window. Set a reminder the day you leave. Because coverage is retroactive, you can delay the decision but not the deadline.
• Assuming small employers offer COBRA. Federal COBRA only applies to employers with 20+ workers. Check your state’s mini-COBRA law if your employer is smaller.
• Forgetting the plan type matters. COBRA continues your existing plan — if it is a restrictive network, that carries over. Review your plan type before deciding.
• Letting a payment lapse. COBRA is unforgiving — miss the grace period and coverage is cancelled with no reinstatement.

Frequently asked questions

Why is COBRA so expensive?

The coverage itself costs the same as it did when you were employed. The difference is that your employer no longer pays its 70–80% share, so you now pay the entire premium plus an administrative fee of up to 2%. The plan did not get pricier — the whole bill simply shifted to you.

How long do I have to sign up for COBRA?

You have 60 days from the date you receive your election notice, or from the date your coverage would end, whichever is later. If you elect, coverage is backdated to the day your old plan ended so there is no gap.

Can I keep my same doctors on COBRA?

Yes. COBRA continues your existing employer plan exactly as it was — same network, same doctors, same deductible and benefits. That continuity is COBRA’s main advantage, especially if you are mid-treatment.

Is COBRA cheaper than an Obamacare plan?

Usually not. Because you pay COBRA’s full premium with no subsidy, an ACA Marketplace plan is often much cheaper — particularly if your income qualifies you for a premium tax credit. Losing job coverage opens a 60-day Special Enrollment Period to shop the Marketplace.

What happens if I miss a COBRA payment?

Monthly payments generally have a 30-day grace period. If you do not pay within it, your coverage is terminated and typically cannot be reinstated. Your first payment has a longer 45-day window after you elect.

Can my family stay on COBRA if something happens to me?

Yes. Spouses and dependent children have their own COBRA rights. For events like divorce, the death of the employee, or a child aging out of dependent status, they can continue coverage for up to 36 months.
