For millions of Americans who leave or lose a job, COBRA is the bridge option: keep your same plan, same doctors, same network — if you can stomach the price.
The catch is that employers typically stop covering their share, so you're suddenly paying the full premium, plus a small administrative fee.
The result is a number that rarely matches what people expect.
According to KFF's annual employer survey, the average annual premium for family coverage in 2024 hit roughly $25,600, with employers covering about $19,300 of that.
A worker losing that subsidy can be staring at a monthly bill north of $2,000.
For single coverage, the average total premium ran around $8,950 a year — roughly $745 a month when you're footing it alone.
You were paying maybe $150 a month out of pocket.
Overnight, the same plan can cost six to eight times more.
COBRA generally gives you 60 days to elect coverage after a qualifying event, and if you enroll, it can be retroactive to the loss date.
Miss it and you're shopping on the open market instead — often during a period when your income just vanished.
There's another trap baked into the math.
COBRA can last 18 months for most job losses, but the plan doesn't get cheaper and the deductible resets.
Meanwhile, a marketplace plan bought through HealthCare.gov may come with subsidies based on your new, lower income — which can slash the sticker price dramatically.
The catch: you can only tap those subsidies during open enrollment or a special enrollment window triggered by losing coverage.
That's why the smartest move isn't to pick one immediately.
Before deciding, gather three numbers: the COBRA monthly premium, your projected household income for the year, and the deductible and out-of-pocket max on each option.
Then check whether your doctors and prescriptions are covered on a marketplace plan, because a cheaper premium that drops your specialists can cost more in the end.
Some states also run their own marketplaces with extra help, and short-term plans exist as a stopgap — though they often exclude pre-existing conditions and skip essential benefits, so read the fine print hard.
If you or a family member has ongoing treatment, COBRA's continuity can be worth the premium.
If you're mostly healthy and cost-sensitive, a subsidized ACA plan frequently wins.
A special enrollment period typically runs 60 days from the coverage loss, and the subsidy calculation depends on the income estimate you submit.
Lowball it and you may owe some back at tax time.
The uncomfortable truth is that COBRA was designed to protect continuity, not affordability.
It does the first job well and the second one badly, and the gap lands squarely on households already absorbing a lost paycheck.
Final Thoughts
Run the numbers the week you lose coverage, not the week the first bill arrives — because in this equation, time is the only variable you still control.
