Why Is COBRA Insurance So Much More Expensive Than What I Paid at Work?
The first COBRA bill arrives after leaving a job, and the number on it looks nothing like what used to come out of a paycheck for the exact same health plan. It’s not a mistake — it reflects a cost that was always there, just mostly hidden until now.
The short answer
COBRA is expensive mainly because the employer subsidy that used to cover a large portion of the premium disappears, leaving the individual responsible for the full cost of the plan, plus an administrative fee that’s commonly added on top. The plan itself hasn’t changed, but the person paying for it is now covering a share that an employer previously absorbed.
Where the employer subsidy actually goes
While employed, most employer-sponsored health plans split the premium cost between the employer and the employee, often with the employer paying a substantial majority. That portion isn’t listed anywhere on a typical pay stub, so it’s easy to underestimate how much of the total premium was actually being covered behind the scenes. Once someone elects COBRA continuation coverage, that employer contribution generally ends, and the full premium — the part that used to come from the paycheck plus the part the employer was quietly paying — becomes the responsibility of the person on COBRA.
The added administrative fee
On top of the full premium, COBRA law generally allows a service or administrative fee to be added, commonly discussed as up to a percentage of the total premium. This fee covers the cost of administering continuation coverage and is a standard, permitted part of how COBRA billing typically works, not a separate optional charge. Combined with the loss of the employer subsidy, this is why the total bill can look dramatically higher than what a former employee remembers paying.
Why some people choose it anyway
Despite the cost, COBRA has a specific advantage: it continues the exact same plan, same doctors, and same coverage without any gap or new deductible period, which matters for people mid-treatment or with ongoing prescriptions. Comparing this option against other ways to keep health coverage after leaving a job is a common step before deciding, since alternatives through a marketplace plan or a spouse’s employer coverage may cost less but could mean a new deductible or a different provider network.
Other coverage gaps COBRA is sometimes used to bridge
Some people use COBRA temporarily to bridge a waiting period before new job coverage becomes active, since new employer plans often have their own waiting period before benefits start. Understanding how an out-of-pocket maximum resets or carries over between plans is also relevant when weighing whether a short, expensive bridge period through COBRA makes more sense than switching plans mid-year.
Worth remembering
COBRA’s high cost isn’t a pricing error or a penalty — it’s the true, unsubsidized cost of the same health plan a person had while employed, with an administrative fee added on top. Understanding where that cost was always coming from can make the decision to use it, or to look at other options, feel less like sticker shock and more like an informed comparison.
