COBRA vs. an ACA marketplace plan after leaving a job
COBRA lets you keep your exact job plan, doctors, and deductible, but you pay the full premium yourself, often $500 to $1,000 a month for an individual. An ACA marketplace plan means a new plan, but losing job coverage opens a 60-day special enrollment period and usually qualifies you for subsidies COBRA can't match, so it is frequently far cheaper. Compare estimated out-of-pocket cost, provider coverage and medication coverage, not just premium, and decide within 60 days, because switching later is hard.
The mistake most people make is treating COBRA as the default. It is the easy button your old employer hands you, so it feels like the safe choice. But because you pay the full premium yourself, COBRA is often two to three times the price of a comparable marketplace plan once subsidies are counted. It is worth 20 minutes to compare before you sign anything.
What each option is
COBRA is a federal law that lets you stay on your former employer's exact health plan, usually for up to 18 months. Same insurer, same network, same doctors, same deductible. The catch: your employer stops chipping in, so you pay the entire premium, both your old share and the part your employer used to cover, plus up to a 2 percent admin fee.
An ACA marketplace plan is coverage you buy for yourself through HealthCare.gov or your state's exchange (check your state’s official website). It is a different plan with its own network and deductible. Crucially, losing job-based coverage triggers a special enrollment period, a 60-day window when you are allowed to sign up outside the normal year-end open enrollment.
The big difference: who pays the premium
At your old job, you probably saw only your share of the premium on your paycheck, maybe $150 a month, because your employer quietly covered the other 70 to 80 percent. COBRA removes that subsidy. The plan did not get more expensive; you are just seeing its true price for the first time.
Take Maria, who left a marketing job in Ohio. Her share of the premium was $180 a month. Her COBRA notice arrives quoting $710 a month for the identical plan, the full cost her employer had been splitting with her. On the marketplace, a similar Silver plan lists at $620 a month, but based on her lower income now that she is between jobs, she qualifies for a subsidy that brings it down to $240 a month. Same level of coverage, roughly a third of the COBRA price. Although provider network and drug coverage can vary significantly so make sure to check those.
COBRA vs. marketplace, side by side
| COBRA | ACA marketplace | |
|---|---|---|
| Your plan | Exact same plan and doctors | New plan, new network to check |
| Who pays | You pay 100% plus up to a 2% fee | You pay, but subsidies often cut the cost |
| Subsidies | Never available | Available for most low-to-middle incomes |
| Deductible | Keeps what you have paid this year | Resets to $0 mid-year |
| How long it lasts | Up to 18 months | As long as you keep buying it |
| Deadline | 60 days from the COBRA notice | 60 days from losing coverage |
Why the marketplace is usually cheaper: subsidies
The marketplace's advantage is the premium tax credit, a subsidy that lowers your monthly bill based on your income. When you have just lost a job, your expected income for the year is often lower, which can mean a large subsidy. COBRA has no equivalent; you always pay full freight.
As a rough guide, subsidies go to households earning roughly 100 to 400 percent of the federal poverty level. In 2026 the enhanced pandemic-era subsidies expired and the old "400 percent cliff" returned, so if you earn above that line you generally get no subsidy and the marketplace may land closer to COBRA in price. Check your own number at HealthCare.gov or use the subsidy calculator from KFF (Kaiser Family Foundation), since this is the single biggest factor in the decision.
The deadline trap (read this before you sign up)
You get 60 days to elect COBRA and 60 days from losing coverage to pick a marketplace plan. The windows overlap, and here is the trap: once you choose, switching later is hard.
Electing COBRA does not cancel your marketplace special enrollment period, as long as you switch within that same 60-day window. But after the window closes, voluntarily dropping COBRA is not a qualifying event. You would be stuck on COBRA until it runs out or until the next open enrollment. Only exhausting your 18 months of COBRA reopens a special enrollment period.
You can always drop COBRA during annual Open Enrollment (November 1 – January 15 in most states) to start an ACA plan on January 1. Otherwise, you must maintain COBRA.
James signed up for COBRA at $680 a month figuring he would "switch to something cheaper next month." Two months later he tried to move to a marketplace plan and learned he could not, because quitting COBRA voluntarily is not a special-enrollment trigger. He had to keep paying $680 until ACA’s open enrollment for a January 1st ACA coverage start date. The lesson: compare before you elect, not after.
A hidden COBRA feature: you can wait to decide
COBRA election is retroactive. You have 60 days to enroll, and if you do, coverage is backdated to the day your old plan ended. In practice this means that if you are healthy and expect a new job's insurance to start soon, you can hold off paying and only elect COBRA if you actually need care during the gap. A doctor visit in that window would be covered once you elect and pay the back premiums. It is a free safety net for a short gap, though it does not help you build toward a deductible.
When COBRA is the better choice
- You have already met your deductible this year. COBRA keeps that progress; a new plan resets it to zero.
- You are mid-treatment or rely on a specific specialist. The same plan means no interrupted care and no network reshuffle.
- A specific prescription is covered well. Switching plans can move a drug to a higher tier or drop it entirely.
- Your income is too high for subsidies. Without a subsidy, the marketplace loses its main price edge.
- You only need to bridge a short gap. Use the retroactive election trick above.
When the marketplace is the better choice
- Your income now qualifies you for a subsidy. This is the common case after a job loss and usually the deciding factor.
- You are comfortable switching plans, or your doctors happen to be in a marketplace plan's network too.
- You want a lower monthly cost and have not built up much deductible yet this year.
- You will be uninsured for more than a few months. Marketplace coverage has no 18-month limit.
How to decide in four steps
- Find your COBRA price. It is on the COBRA election notice your employer or its administrator mails you. This is the real number, not your old paycheck deduction.
- Get a marketplace quote with your subsidy. Go to HealthCare.gov or your state exchange (check your state’s official website), enter your expected income for the year, and look at the after-subsidy price.
- Check your doctors and drugs. Look up whether your current providers and prescriptions are covered in the marketplace plan you are considering.
- Compare total annual cost, not just premium: monthly premium times 12, plus the deductible you would have to re-meet on a new plan. If you have already spent your deductible this year, weight that heavily toward COBRA.
Don't forget the deductible reset
One cost that is easy to miss: switching to any new plan mid-year resets your deductible and out-of-pocket maximum to zero. If it is November and you have already paid down a $3,000 deductible, a cheaper-looking marketplace plan could cost you far more once you start paying that deductible over again. COBRA carries your year-to-date spending with it. Early in the year this barely matters; late in the year it can flip the whole decision.
Bottom line
Don't default to COBRA just because it is the form in front of you. If your income has dropped, a subsidized marketplace plan is frequently half the price or less for comparable coverage. COBRA earns its keep when you have met your deductible, you are mid-treatment, or you just need to bridge a short gap. Whichever you choose, run the comparison inside your 60-day window, because switching later is much harder than people expect.
Frequently asked questions
Is COBRA or an ACA marketplace plan cheaper?
For most people who have just lost a job, a marketplace plan is cheaper, often much cheaper. COBRA charges the full premium your employer used to subsidize, commonly $500 to $1,000 a month. A marketplace plan is usually eligible for income-based subsidies, and your income after a job loss is often low enough to qualify for a large one. COBRA wins mainly when your income is too high for subsidies or you have already met your deductible for the year.
How long do I have to choose between COBRA and the marketplace?
You have 60 days for each. You get 60 days from the date on your COBRA election notice to elect COBRA, and 60 days from the day you lose job coverage to pick a marketplace plan through a special enrollment period. The windows overlap, so compare both before you commit, because switching after the window closes is difficult.
Can I drop COBRA later and switch to a marketplace plan?
Usually not right away. Voluntarily cancelling COBRA is not a qualifying life event, so it does not open a special enrollment period, and you would have to wait for year-end open enrollment. The exception is running out of COBRA: once you exhaust your 18 months, that loss of coverage does trigger a special enrollment period. This is why it is important to compare before electing COBRA, not after.
Does losing my job qualify me for a special enrollment period?
Yes. Losing job-based health coverage is a qualifying life event that opens a 60-day special enrollment period on the ACA marketplace, whether you quit, were laid off, or had your hours cut below the coverage threshold. You can enroll in the 60 days before or after your coverage ends. Losing coverage because you did not pay your premium does not count.
What happens to my deductible if I switch to a new health plan mid-year?
It resets to zero. Deductibles and out-of-pocket maximums run on the plan year, so any amount you have already paid does not carry over to a brand-new plan. Staying on your old plan through COBRA preserves your year-to-date progress. This is why switching late in the year, after you have paid down a big deductible, can cost more than it appears even if the new plan's premium is lower.
