Losing a job or having your hours cut is stressful enough without having to think about health insurance on top of it. If you had coverage through your employer, one of the first questions that comes up is whether you can keep it. The answer, for many people, is yes — through a federal law called COBRA. But “yes” comes with some important fine print about cost and timing that’s worth understanding before you decide what to do.
What COBRA continuation coverage is and who is eligible
COBRA stands for the Consolidated Omnibus Budget Reconciliation Act, and it does one specific thing: it lets you temporarily stay on the same group health plan you had through your job, even after you leave that job. The coverage itself doesn’t change. Same doctors, same network, same plan documents. What changes is who pays for it.
COBRA generally applies to employers with 20 or more employees, and it kicks in after certain “qualifying events.” A layoff or reduction in hours are two of the most common triggers, but COBRA also covers other situations, like a divorce or a dependent aging off a parent’s plan. You’re typically eligible if you were enrolled in your employer’s group health plan the day before the qualifying event.
It’s worth noting that COBRA doesn’t apply if you were fired for gross misconduct, and it doesn’t apply to very small employers in most cases — though some states have their own versions that fill in that gap, which we’ll get to later.
Once you’re eligible, COBRA lets you continue coverage for a limited period, usually up to 18 months after a layoff or hours reduction, though certain circumstances can extend that further. It’s meant to be a bridge, not a permanent solution.
How COBRA premiums are calculated — and why they’re often a shock
Here’s the part that catches a lot of people off guard. While you were employed, your employer likely paid a significant chunk of your monthly premium, and you only saw a smaller amount deducted from your paycheck. Under COBRA, that employer contribution disappears. You become responsible for the entire premium — both the portion you used to pay and the portion your employer used to cover.
On top of that, plans are allowed to charge up to an additional 2% as an administrative fee. So your COBRA bill reflects the full, unsubsidized cost of the group plan, plus a small service charge. For many people, this means their monthly premium jumps substantially compared to what was coming out of their paycheck before.
This is the single biggest reason people hesitate to use COBRA. The coverage itself may be excellent, but paying the full group rate out of pocket, right after a loss of income, can be a serious strain on a household budget. It’s a good idea to request the exact premium amount in writing from your plan administrator rather than estimating, since it can vary based on your specific plan tier and family coverage level.
Critical deadlines: don’t let the clock run out
COBRA comes with strict timelines, and missing them can mean losing the option entirely.
After your qualifying event, your employer or plan administrator is required to send you an election notice explaining your COBRA rights. Once you receive that notice, you generally have 60 days to decide whether to elect COBRA coverage. This is called the election period, and it’s one of the most important deadlines in the whole process.
A few things are worth understanding about how this works in practice:
You don’t have to decide immediately. The 60-day window gives you time to weigh your options, compare costs, and figure out what makes sense for your household.
If you do elect COBRA, coverage is retroactive to the date you lost your job-based insurance, as long as you pay the premiums, including any that built up while you were deciding. This means there generally isn’t a gap in coverage if you eventually enroll, even if you take a few weeks to decide.
After electing coverage, you typically also get an initial grace period to make your first premium payment, and ongoing monthly payments usually have their own grace period as well, often around 30 days. Missing a payment deadline can result in losing coverage, so if you go this route, it helps to treat the premium due date as seriously as rent or a mortgage payment.
Because these deadlines are federally set but administered by individual plans, always double-check the specific dates listed on your own election notice rather than relying solely on general timeframes.
How COBRA compares to Marketplace plans or Medicaid
Before committing to COBRA, it’s worth comparing it against two other paths: an ACA Marketplace plan or Medicaid, if you qualify based on income.
Losing job-based coverage is considered a qualifying life event for the ACA Marketplace, which means you get your own special enrollment window — typically 60 days from the date you lost coverage — to sign up for a Marketplace plan outside the normal open enrollment period. Depending on your household income, you may qualify for premium tax credits that significantly lower your monthly cost. For many people whose income has dropped because of a layoff, a subsidized Marketplace plan ends up costing far less per month than COBRA, even though the network or specific plan design might be different.
Medicaid is the other major option. Eligibility depends on your state and your current household income, and since Medicaid eligibility is often based on your income going forward rather than your past salary, a job loss can sometimes newly qualify you even if you didn’t qualify before. Medicaid, when you’re eligible, typically has little to no premium cost, which makes it worth checking regardless of what you assumed about eligibility in the past.
The tradeoff with both alternatives is that switching plans may mean a different network of doctors, different drug formularies, or a gap while paperwork processes. COBRA’s advantage is continuity — same coverage, no new plan to learn, no risk of a preferred doctor being out of network. It’s a real tradeoff between cost and continuity, and the right answer depends on your specific health needs, current providers, and budget.
Special enrollment rights if you skip COBRA
You are never required to take COBRA. If you decide it’s too expensive, you still have options, and you won’t be penalized for declining it.
As mentioned above, losing job-based coverage triggers a special enrollment period for the ACA Marketplace, generally lasting 60 days from your loss of coverage date. This is true whether or not you were offered COBRA. You don’t need to elect and then cancel COBRA to access this window — declining it outright still preserves your right to enroll in a Marketplace plan through this special period.
One important timing note: if you elect COBRA and later want to switch to a Marketplace plan, you generally can’t do so until COBRA runs out or during the next open enrollment period, unless you have another qualifying event. This is different from declining COBRA upfront. If there’s a chance you’ll want Marketplace coverage instead, it’s usually simpler to decide before your COBRA election window closes rather than switching partway through.
Medicaid, by contrast, doesn’t work on the same enrollment-period system. You can apply for Medicaid at any time of year if you believe you might be eligible based on your current income and household size.
State continuation coverage laws
Federal COBRA has some gaps — most notably, it generally doesn’t apply to businesses with fewer than 20 employees. If you worked for a smaller company, you might assume you have no continuation option at all, but many states have their own continuation coverage laws, sometimes informally called “mini-COBRA” laws, that extend similar protections to employees of smaller businesses.
These state laws vary quite a bit. Some cover different lengths of time than federal COBRA, some apply to different size employers, and some have different rules about premium costs or eligibility. Because the details differ so much from state to state, the most reliable way to find out what applies to you is to check with your state’s department of insurance or ask your former employer’s HR or benefits department directly whether a state continuation law applies to your situation.
If you’re comparing options after a layoff, it’s worth checking all three doors — federal COBRA, your state’s continuation law if you worked for a smaller employer, and the ACA Marketplace or Medicaid — before deciding. Costs and rules shift enough from case to case that a side-by-side comparison, done early while your election windows are still open, is usually the safest way to avoid both a coverage gap and an unnecessarily high bill.
