COBRA Health Insurance Explained: Costs and Deadlines and Smarter Options

Losing a job is hard enough. Then a thick envelope shows up a few weeks later with the word COBRA on it. You open it and see the monthly price. And for a second you wonder if it’s a typo.

It usually isn’t. COBRA lets you keep your work health plan after you leave. But you now pay the whole bill yourself. This guide explains how COBRA health insurance works and what the deadlines are. It also shows when COBRA makes sense and when a different option could save you a lot of money.

The quick answer

COBRA is a federal law that lets many workers and their families keep their employer health plan for a limited time after leaving a job or losing hours. Coverage usually lasts 18 months. You can be charged up to 102% of the full plan cost. You get at least 60 days to decide. Before you sign up, compare it with a Marketplace plan because losing job coverage also opens a special enrollment window there.

Who can get COBRA

Federal COBRA generally applies to private employers with 20 or more employees and to state and local governments. If you were on the plan the day before a qualifying event you’re usually eligible. Your spouse and dependent children on the plan may be eligible too.

Qualifying events include these.

• Losing your job for any reason other than gross misconduct
• Having your hours cut so you no longer qualify for the plan
• Divorce or legal separation from the covered employee
• Death of the covered employee
• A child aging out of dependent coverage
• The covered employee becoming entitled to Medicare

Work for a smaller company? Many states have their own continuation laws often called mini-COBRA. Your state insurance department can tell you if one applies.

The deadlines that matter most

This is where people get hurt. The dates are strict and missing one can end your coverage for good.

Here’s a detail that confuses people. COBRA is retroactive. If you elect within the window and pay on time, coverage goes back to the day your job coverage ended. That’s why some people wait and only elect if they need care. It’s legal but it’s risky if you lose track of the dates.

Why COBRA costs so much

While you worked your employer probably paid a large share of your premium. On COBRA you pay all of it plus up to 2% for admin costs. So the plan didn’t get more expensive. You’re just seeing the full price for the first time.

That number can be a real shock for families. It’s the main reason to compare other options before you decide.

When COBRA makes sense

• You’re in the middle of treatment and want to keep the same doctors
• You’ve already met most of your deductible this year
• You expect a new job with benefits soon and want a short bridge
• Your doctors aren’t in any affordable Marketplace network
• Someone in your family has a pregnancy or surgery coming up

Honestly that deductible point is big. Starting a new plan midyear often means starting your deductible over from zero.

When another option may be better

Losing job-based coverage gives you a special enrollment period on the Health Insurance Marketplace. You generally have 60 days to pick a plan. Depending on your new income you may qualify for a premium tax credit that lowers your monthly bill.

Keep in mind that the extra pandemic-era subsidies ended after 2025. Help in 2026 is generally limited to households earning up to 400% of the federal poverty level. Use the tools at HealthCare.gov or your state marketplace to see real prices with your income.

Other choices may include these.

• Joining a spouse’s employer plan because job loss is usually a qualifying event
• Medicaid if your income drops low enough in your state
• A student health plan if you’re in school
• Medicare if you’re 65 or older

The Medicare trap to watch

If you’re 65 or close to it, slow down here. COBRA doesn’t count as current employer coverage for Medicare Part B timing. If you delay Part B because you’re on COBRA you could face a late penalty and a gap later. You generally have eight months after your job or job coverage ends to sign up for Part B without a penalty.

How to decide step by step

Step 1: Find your COBRA notice and write down the election deadline and the monthly cost.

Step 2: Check how much of your deductible and out-of-pocket maximum you’ve already met this year.

Step 3: Go to HealthCare.gov or your state marketplace and price plans using your expected income.

Step 4: Check whether your doctors and medicines are covered under the Marketplace plans you like.

Step 5: Compare the full yearly cost of each option and not just the monthly premium.

Step 6: Pick one and put every payment date in your phone calendar with reminders.

A hypothetical example

Picture a worker laid off in late summer. His wife is pregnant and due in a few months. They’ve already met most of their deductible this year. COBRA is pricey but it keeps the same doctors and hospital and the deductible progress. For this family a short stretch of COBRA might be worth it.

Now picture a single person laid off in January with no ongoing care. A Marketplace plan with a tax credit may cost far less.

These are only illustrations. But they show why the same choice isn’t right for everyone.

Questions to ask HR before your last day

If you still have a few days at work this is the best time to get answers. HR is much easier to reach while you’re still on the payroll.

• On what exact date does my current health coverage end
• Who sends the COBRA notice and when should I expect it
• What will the monthly COBRA cost be for medical and dental and vision
• Will the company pay any part of COBRA as part of my severance
• How do I make payments and is autopay available
• Can I get a copy of my current plan’s summary of benefits

That severance question is worth asking out loud. Some employers do cover a few months of COBRA. It isn’t required but it happens more often than people think. And if they offer it, get it in writing.

Common mistakes with COBRA health insurance

• Missing the election deadline because the paperwork got buried
• Paying late and losing coverage after the grace period
• Choosing COBRA without checking Marketplace prices first
• Missing the 60-day Marketplace special enrollment window
• Delaying Medicare Part B because of COBRA
• Forgetting that dental and vision may have separate COBRA prices

Frequently asked questions

Can I drop COBRA if I find a cheaper plan?

Yes. You can end COBRA anytime. But dropping COBRA on purpose usually doesn’t open a new Marketplace enrollment window outside open enrollment. Plan the switch carefully.

Does my employer have to tell me about COBRA?

Yes. Your plan must send you an election notice with the cost and deadlines after a qualifying event.

Can I keep COBRA for just my kids?

Often yes. Each eligible family member can usually make their own choice.

If your college-age child is losing coverage, check the cheaper options for health insurance for college students before you pay for COBRA.

A calm way to finish

COBRA can be a lifeline when you need to keep your doctors. It can also be an expensive habit when a better option is waiting. Mark your deadlines. Compare the real yearly costs. Then choose with clear eyes.
