The letter lands in the mailbox with no warning.
A job ends, and suddenly the same health plan that quietly came out of a paycheck now arrives as a standalone bill.
For a family of four, that number can run $1,900 to $2,400 a month, according to 2025 employer survey data.
That's a mortgage payment for a product most people never had to price on their own.
Employers typically cover 70% to 85% of premiums for workers.
Under COBRA, the former employee pays both shares plus a 2% administrative fee.
That math turns a $300 payroll deduction into $1,100 or more overnight.
It's simply the removal of a subsidy people didn't know they had.
You have 60 days from the date coverage would end to elect COBRA, and the coverage is retroactive once you pay.
Miss the deadline and the option disappears entirely.
There's no grace period, no appeal, no second chance.
Many people assume they must take COBRA because it's the only way to keep their doctors.
The ACA marketplace has open enrollment every fall, but losing job-based coverage triggers a special enrollment period.
You get 60 days from the loss of coverage to sign up, and subsidies are based on your projected income for the year, not last year's salary.
A marketplace silver plan often costs less than COBRA for the same household, especially if income drops after a layoff.
In some states, expanded Medicaid covers adults below certain income thresholds at little or no monthly cost.
A short-term gap is another route, though those plans often exclude pre-existing conditions and skip maternity and mental health coverage.
Dental and vision are usually separate COBRA elections, and you can pick one without the other.
If you've already met your deductible this year, COBRA may be worth the premium for a few months, since switching plans resets that number to zero.
Prescription users should check formularies carefully before jumping ship.
One more thing: COBRA is a bridge, not a destination.
It was designed to cover gaps, and most people who use it do so for under a year.
Treat the 60-day window as a research sprint, not a panic button.
Compare at least three options, check whether your doctors are in-network, and confirm the first payment due date in writing.
It's that losing a job means losing a hidden subsidy worth thousands of dollars a year, and most people find out only when the bill shows up.
Final Thoughts
Knowing the rules ahead of time is the difference between a manageable transition and a financial gut punch.
