Here's one of the most common calls we get in the health insurance world: someone just left a job (retirement, layoff, resignation, didn't matter), they got the COBRA letter in the mail, and they're staring at the premium going "this can't be right, right?"
It's right. COBRA is expensive. And the good news is: COBRA is almost never your only option. You've got a buffer, you've got alternatives, and if you understand how all of this works, you can usually come out ahead financially without going uninsured.
What COBRA actually is
COBRA stands for the Consolidated Omnibus Budget Reconciliation Act of 1985. We looked it up. Nobody uses the full name. But the law lets you continue your employer's health coverage after you leave the job — up to 18 months in most cases.
A few requirements:
- You had to be on the employer's plan while employed
- The employer has to have 20+ full-time-equivalent employees
- The reason you're leaving has to qualify (layoff, retirement, resignation, divorce from the employee, etc.)
If you waived benefits while employed, COBRA doesn't apply — there's nothing to continue.
The sticker shock explained
Here's why COBRA is so expensive compared to what you were paying. When you were employed, your employer was almost certainly paying a chunk of your premium — often $400-800 per month per employee. You only saw the portion that came out of your paycheck.
On COBRA, you pay the full cost of the plan. Plus a small administrative surcharge (usually 2%). So if the true cost of your plan was $1,200/month, and your employer was paying $700 of that, you were only writing a check for $500. On COBRA, you're writing a check for $1,224.
Your employer doesn't have to contribute when you're no longer with the company. You're paying the actual cost of the plan now.
The genius hidden feature of COBRA (worth knowing)
Here's a detail about COBRA that most people never learn: you have 60 days from your qualifying event to decide whether to enroll. And if something happens during those 60 days — accident, illness, hospital visit — you can retroactively enroll and get it covered.
That means COBRA is essentially a free safety net for 60 days after you leave your job, even if you're not paying for it. You just have to pay the back premium if you actually need to activate it. Smart move: hold off on paying COBRA, see if your new coverage kicks in during the window, and only pay for COBRA if you actually need to.
Your real options when leaving a job
Option 1: COBRA
Pros: Same plan you had, same doctors, same network, no re-qualification needed. Pre-existing conditions aren't an issue because you're continuing existing coverage.
Cons: Expensive. Capped at 18 months. Still subject to the employer's open enrollment timeline and plan changes.
Option 2: Healthcare.gov / state marketplace (ACA)
Pros: Depending on income, you may qualify for premium tax credits that bring the cost way down. Can be a great option for people whose income drops significantly after retirement or job loss.
Cons: Narrower networks than most employer plans. Deductibles can be high. Not every plan is accepted by every doctor. Service levels vary dramatically by carrier and region.
Option 3: Health share / health sharing ministries
Not technically insurance, but a lot of people use them when they need basic coverage without the ACA price tag. Monthly costs are typically much lower, but there are usage restrictions (what qualifies for sharing varies), waiting periods, and these are not regulated like insurance.
Pros: Dramatically cheaper for healthy people. Catastrophic protection.
Cons: Not insurance (so no legal guarantee of coverage). Pre-existing exclusions. Not accepted at every provider.
Option 4: Private health insurance
If you don't qualify for ACA subsidies and you have specific health needs, there are private plans worth looking at. These vary widely by state.
The Medicare bridge (if you're close to 65)
If you're retiring before you're Medicare-eligible, the question becomes "how long is this bridge?":
- Under 6 months to 65: COBRA or short-term coverage usually makes sense — bridge yourself to Medicare, then enroll.
- 6-18 months to 65: This is where ACA or health sharing often win on math.
- 18+ months to 65: COBRA runs out before you qualify for Medicare anyway. You'll need another plan at some point, so start with the long-term option now.
Important note: if you're already 65 and still working with employer coverage, do NOT turn on Medicare Part B unless you need to. There's a 6-month "guaranteed insurability" window that starts when Part B begins. If you have pre-existing conditions, you want that clock to start when you actually need Medicare, not before.
The one thing you should always do first
Call a licensed independent insurance broker before making your decision. Even if you end up on COBRA, at least you'll have run the alternatives. There is no cost to this — brokers get paid by the carrier if you end up buying through them, and most reputable ones don't charge separate fees.
Don't ask your HR department
This might be a controversial take, but we've been doing this a long time: most HR departments, even at big companies, don't actually understand health insurance well. They know how to administer the plan. They don't necessarily know how it compares to alternatives, what COBRA will truly cost you over time, or whether the ACA would be cheaper. If you need the COBRA letter or paperwork, call the carrier directly — they're the ones sending it. For actual advice on whether COBRA is the right choice, call an independent broker.
The honest bottom line
Leaving a job is already a stressful transition. Don't add "accidentally overpaying for health insurance for 18 months" to the stack. COBRA is a legitimate option — sometimes the right one. But it's one option out of several, and defaulting to it just because it's the first letter you got in the mail can cost you tens of thousands of dollars over the next couple of years.
Shop. Compare. Ask questions. The right answer depends on your situation — your income, your health, your doctors, how long until Medicare — and it almost never looks the same for two people.
