About 80% of people offered COBRA never sign up, and most who do are paying more than they need to because they didn’t know the Marketplace alternative existed. COBRA lets you keep your former employer’s health plan. The cost is the full premium plus a 2% admin fee. What your employer used to pay, you now pay. For a family, that’s often $1,800 to $2,400 a month.
The law around COBRA (the Consolidated Omnibus Budget Reconciliation Act) is strict, but there are more myths about it than facts circulating. Here’s what’s real.
“I have to decide about COBRA in a couple weeks.”
You actually have 60 days from the later of two dates: the date your coverage would end, or the date your employer mails the election notice. Whichever comes second starts the clock.
That’s nine weeks. You can take the full window, sign up on day 59, and the coverage reinstates retroactively to the day you lost it. If you had a doctor visit in between, it’s covered.
Don’t reflexively elect COBRA the day after a layoff because HR said to. Price out the Marketplace and Medicaid first. The HR form has a checkbox. Your wallet has a number.
“COBRA is too expensive. There’s no alternative.”
Losing employer coverage triggers a Special Enrollment Period on the ACA Marketplace that lasts 60 days. You can pick a plan there, often with premium tax credits that cut your cost significantly. A family that would pay $1,900/month on COBRA might pay $400/month on a Marketplace silver plan with subsidies.
Go to healthcare.gov (or your state exchange) within 60 days of losing coverage. Enter your expected annual income, not last year’s, but what you project for this year. See what subsidies apply. Compare those premiums and deductibles against your COBRA quote.
Don’t skip the Marketplace because you assume you make too much. Subsidies extend up to 400% of the Federal Poverty Level, and under enhanced subsidy rules through 2025 many income ranges had better numbers. For 2026, pre-ARPA rules are back (see ACA Marketplace), but the Marketplace still beats COBRA for most people under 400% FPL.
“COBRA covers me for up to 3 years automatically.”
Actually, duration depends on the qualifying event:
18 months for voluntary quit, termination (except gross misconduct), reduction in hours. Covers most separations.
29 months if you become disabled during the first 60 days of COBRA and qualify for SSDI. Called the disability extension.
36 months for dependents if the qualifying event is the employee’s death, divorce, or a child aging off the plan.
After the maximum runs out, you get a single 60-day window to transition to the Marketplace. Look at the calendar date COBRA ends and start planning next coverage before that date.
COBRA doesn’t auto-renew. Coverage ends the day the 18-month (or 36-month) clock runs out.
“COBRA only applies if you were laid off.”
COBRA applies to most employment separations except gross misconduct. Voluntary resignations (quitting) count. Terminations (with cause other than gross misconduct) count. Layoffs and reductions in force count. Reduced hours that drop you below plan eligibility counts. Aging out of dependent status at 26 counts. Divorce from the covered spouse counts. Death of the covered employee counts for family members.
Gross misconduct has a narrow legal definition. Theft, violence, fraud might qualify, but showing up late doesn’t. If your employer claims gross misconduct and denies COBRA, you can appeal to the Department of Labor, and they usually side with the former employee.
Don’t assume you’re ineligible because you quit. File anyway. And look at other options after leaving a job.
“If I’m on COBRA, I can’t use Medicaid or the Marketplace.”
You can switch off COBRA to Medicaid or Marketplace coverage during open enrollment or if you qualify for a Special Enrollment Period. SEPs that apply: marriage, birth, adoption, a move to a new coverage area, newly eligible for Medicaid, or income dropping enough to qualify for better subsidies.
Re-evaluate every year at open enrollment (November 1 to January 15 for most states). Premiums and subsidies change, and so does your income.
Don’t stay on COBRA by default because it’s the familiar plan. Familiarity gets expensive.
“COBRA and the Marketplace are basically the same.”
Three differences matter.
Your doctors and networks. COBRA keeps you on exactly the plan you had: your doctor, your pharmacy, your specialist, your in-progress treatment. Marketplace plans often use different and narrower networks.
Your deductible. If you’ve already hit your deductible on the employer plan this year, COBRA preserves that progress as long as you stay on the same plan. A new Marketplace plan starts your deductible fresh at zero.
Cost. COBRA is almost always more expensive out-of-pocket unless you’re above the Marketplace subsidy range.
If you’re mid-chemo, mid-pregnancy, or deep into a deductible, COBRA might actually save money for the rest of the calendar year. Run the math.
“I can enroll in COBRA whenever I want.”
60 days from when you lost coverage or received the election notice, whichever is later. Miss it and COBRA is gone. Your employer isn’t required to offer a second chance.
Put the 60-day deadline in your phone calendar the day you get the election notice. Don’t throw the HR packet in a drawer.
“COBRA cost is something HR sets.”
COBRA cost is federally limited to 102% of the full premium: 100% of your and your employer’s combined cost plus a 2% admin fee. Your employer doesn’t mark this up. What they charge is what it actually costs.
The shock is realizing how much of your premium your employer was paying all along. A typical employer plan deducts $150 biweekly from your paycheck ($325/month). COBRA then bills $1,400/month because the employer was quietly paying the other $1,075.
Ask HR for the exact COBRA monthly rate in writing before you elect. It should match your open enrollment paperwork’s “total premium” line.
The retroactive election most people never use
If you get sick or injured during the 60-day election window and haven’t signed up yet, you can still elect COBRA after the fact and coverage kicks in retroactively to the day you lost employer coverage. Pay the back premiums and the medical bill gets covered.
This is why many people wait out the 60 days. If nothing happens, they skip COBRA and save the money. If something expensive does happen, they elect on the spot.
Understand this option exists before you need it.
What to compare before electing
Before you check the COBRA box, price out:
- Marketplace premium after subsidies for a comparable silver plan, using your expected 2026 income at healthcare.gov
- Medicaid eligibility if your income is under roughly 138% FPL (about $22,000 single, $45,500 family of four) in expansion states. See Medicaid eligibility.
- Spouse’s employer plan, if they have coverage and a special enrollment due to your job loss
- Short-term medical plans, which are cheaper but usually don’t cover pre-existing conditions. Risky if you have ongoing care.
- CHIP for the kids. If household income drops enough, CHIP covers children for $0 or close to it, even if you take COBRA for yourself.
After a termination, COBRA is one piece
If you were recently terminated, COBRA is one of several decisions hitting at once. Also look at unemployment benefits,SNAP if income dropped, and retirement decisions like what happens to your 401(k) when you leave. Each of these has its own 30-90 day window. They all compete for attention in the first month after separation.
The HR exit packet isn’t a menu of things to say yes to. It’s a menu of options, and some of them have cheaper alternatives outside the packet. COBRA is one of those.
