How COBRA Actually Works After You Leave a Job
Updated: 2 days ago
Losing job-based health coverage is stressful enough without also being unsure how COBRA actually works. Here's the mechanics, in the order you'll actually run into them.
What COBRA Actually Is
COBRA isn't a new insurance plan — it's the right to keep the exact same group health plan you had as an employee, with the exact same coverage and network, after you leave. The only real change is who's paying for it: your former employer usually covers part of the premium while you're employed, but under COBRA you pay the full cost yourself, plus up to an extra 2% to cover administrative costs.
The Clock Starts With the Election Notice
You don't have to decide on the spot. Once you receive your COBRA election notice, you have 60 days to choose whether to elect coverage. That's 60 days from the later of the date the notice is provided or the date you lose coverage, not simply from your last day of work — so if the notice is delayed, your decision window shifts with it.
You Don't Have to Pay Right Away, Either
Electing COBRA and paying for it are two separate steps. Once you elect, you have 45 days to make your first premium payment. If you elect and pay within these windows, your coverage is retroactive — meaning there's no actual gap between your job-based coverage ending and your COBRA coverage starting, even if you took most of the 60 days to decide. After that first payment, each month's premium gets a 30-day grace period; miss that window and coverage ends.
How Long It Actually Lasts
Standard COBRA coverage runs 18 months. Two situations can extend it: if you're determined disabled by the Social Security Administration within the first 60 days of COBRA coverage, your whole family's coverage can extend to 29 months. And if a second qualifying event happens during that original window — the covered employee dies, becomes entitled to Medicare, or a divorce/dependent losing eligibility occurs — coverage can extend to 36 months for the affected family members.
What It Actually Costs
Because you're paying the full premium instead of just your employee share, COBRA is usually a real jump in monthly cost compared to what came out of your paycheck before. It's not a discount program — it's access to the same coverage at the real cost of that coverage. That's worth knowing going in, since it's the single most common surprise people run into.
Final Thoughts
COBRA exists to prevent a hard gap in coverage, not to be the cheapest option available. Knowing the actual timeline — 60 days to elect, 45 days to pay, retroactive once you do — means you can use that window deliberately instead of scrambling, whether you end up sticking with COBRA or comparing it against marketplace coverage in the meantime.
