Your last day is the 15th. Your health coverage ends the last day of the month. You’ve got a prescription that needs refilling, a kid with a checkup booked in three weeks, and an envelope from your employer’s benefits administrator with the word COBRA on it. The question on your mind is simple: do you take it, and can you afford it?
COBRA is one option for staying covered after a job ends. It’s often not the cheapest one, and for a lot of people it shouldn’t be the default. Here’s what it actually is, what it costs, and how it stacks up against the alternatives so you can pick on purpose instead of by panic.
What COBRA is
COBRA lets you keep the exact health plan you had at work after a qualifying event, and losing your job is the most common one. Same insurer, same network, same doctors, same coverage. It applies to employers with 20 or more employees. If your company was smaller, many states have their own “mini-COBRA” laws that do something similar, so it’s worth asking.
The reason people flinch at COBRA is the price. While you were employed, your employer paid a big chunk of your premium and you never saw it. On COBRA, you pay the entire premium, the employer’s share plus your share, and the plan can add an administrative fee of up to 2 percent. So your monthly cost is up to 102 percent of the full premium. That’s not COBRA gouging you. It’s just the true cost of the plan, finally landing on your bill in full.
The deadlines that matter
Two clocks start when your coverage ends, and missing either one closes a door.
You have 60 days to elect COBRA, counted from the later of the date your coverage ends or the date you receive the election notice. Here’s the part most people don’t know: COBRA is retroactive. If you elect and pay, coverage reaches back to the day your old plan stopped, with no gap. That means you can technically wait, stay uninsured on paper, and only elect if you actually rack up a medical bill during those 60 days. It’s a real strategy, and it’s also a gamble, because a serious emergency on day 20 could leave you scrambling.
COBRA coverage for a job loss generally lasts up to 18 months. Some other qualifying events stretch to 36 months, and a disability can extend it to 29.
The comparison nobody walks you through
COBRA is rarely the only or the best choice. Before you sign, weigh it against three alternatives.
The ACA marketplace is the big one. Losing job-based coverage opens a 60-day special enrollment period, the same length as your COBRA window. Marketplace plans frequently cost far less than COBRA, especially if your income dropped, because you may qualify for premium tax credits that lower the monthly cost. One important 2026 change: the enhanced subsidies that made marketplace plans extremely cheap from 2021 through 2025 lapsed on January 1, 2026, so premiums went up this year. Even so, for someone whose income just fell off a cliff, the marketplace is usually still cheaper than paying 102 percent of a full premium. Run your actual numbers at HealthCare.gov before assuming anything.
Medicaid is the next option, and if your current monthly income is low enough, it’s almost always the cheapest path, often free. Because Medicaid counts your income now rather than last year’s, a job loss can qualify you even if you earned well before. Our guide to Medicaid eligibility after job loss covers the income limits and how to apply, and unlike the others, Medicaid has no enrollment window at all.
A spouse’s employer plan is the one people overlook. Your job loss is a qualifying event that usually lets you join your spouse’s coverage within about 30 days. If your partner has a decent plan at work, hopping onto it can beat all three of the above.
A decision tree for which one to pick
Start at the top and follow the first branch that fits.
- Is your income now low or near zero?
- Yes: Check Medicaid first. If you qualify, it’s the cheapest coverage and you can apply today.
- No: Keep going.
- Does your spouse or partner have employer health insurance?
- Yes: Look at joining their plan within roughly 30 days of your job ending. Often the lowest cost with the least hassle.
- No: Keep going.
- Are you in the middle of treatment, partway through your deductible, or determined to keep your exact doctors with zero interruption?
- Yes: COBRA is the strongest fit. It keeps everything identical, and your year-to-date deductible carries over instead of resetting.
- No: Compare a subsidized marketplace plan against COBRA on price. For most people without a mid-year medical situation, the marketplace wins on cost.
The deductible point deserves a flag. COBRA keeps the same plan, so any deductible you’ve already met this year stays met. Switch to a marketplace or Medicaid plan and the deductible clock resets to zero. If you’re in October and you’ve already paid down a big deductible, that alone can tip the math toward COBRA for the rest of the year.
How to actually elect COBRA
If COBRA is your answer, the steps are short. Watch for the election notice from your plan administrator, which has to go out within set timeframes after your coverage ends. Complete the election form and return it before your 60-day deadline. Make your first premium payment, which is also time-limited and triggers your retroactive coverage. Then keep paying on time every month, because a late payment can cancel COBRA permanently with no second chances.
There is a little breathing room on the monthly payments. After your initial payment, you generally get a grace period of about 30 days to make each monthly premium. That helps in a tight month, but don’t lean on it, because once a payment misses the grace period the plan can terminate your coverage and isn’t required to reinstate it. Set a reminder a few days before each due date.
A word on the sticker shock. Because you’re paying the full premium plus the 2 percent fee, an individual plan can run several hundred dollars a month and a family plan well over a thousand. That’s not a markup, it’s what your coverage always cost. Seeing the real number is exactly why running the marketplace and Medicaid comparison first is worth an hour of your time.
Don’t sort this out in isolation
Health insurance is one of several things that shift the day a job ends. You may have an unemployment claim to file, retirement money to deal with, and a final paycheck to chase down. Our complete guide to benefits after termination maps the whole picture, and if the job ended in a firing, start with filing unemployment after being fired so the income side is moving too.
For the full rules, costs, and timelines, the COBRA hub goes deeper, and the ACA marketplace guide covers the alternative most people end up choosing. The worst outcome here is doing nothing and going uninsured. The second worst is grabbing COBRA on autopilot when a cheaper plan would have covered you just as well.
