COBRA vs ACA Marketplace: Which Is Cheaper After You Lose Your Job?
Why COBRA is so expensive
While you were employed, your employer quietly paid most of your premium — often 70% or more. You only ever saw the small slice deducted from your paycheck. COBRA continuation lets you keep that identical plan, but the law now lets the plan charge you the full premium plus up to a 2% administrative fee. Nothing about the coverage changes; the entire employer subsidy simply disappears and lands on you.
That is why a plan that felt like it cost $150 a month from your paycheck can suddenly cost $650, $900, or more on COBRA. According to the U.S. Department of Labor, COBRA generally lasts up to 18 months (sometimes 36 in specific circumstances), and you have 60 days to elect it. The sticker price is the single biggest reason people look elsewhere.
The Special Enrollment Period changes everything
Here is the fact most people miss during a layoff: losing job-based coverage is a qualifying life event that triggers a 60-day Special Enrollment Period (SEP) on the ACA marketplace. You do not have to wait for the annual open enrollment window. Within those 60 days, you can enroll in a marketplace plan that starts as early as the first of the following month.
This matters because it gives you a real choice. You are not forced onto COBRA by default — you can compare COBRA against a marketplace plan and pick the cheaper option. To size that difference over your expected gap, the COBRA vs ACA calculator totals both paths side by side. Be careful with the clock: the SEP is 60 days from the date coverage ends, and missing it can leave you waiting until open enrollment.
How subsidies drop the price after your income falls
ACA premium tax credits are based on your expected annual income, not last year's salary. After a layoff, your income for the rest of the year usually falls sharply — and as it falls, your subsidy rises. This is the opposite of COBRA, where the price is fixed at the full employer premium regardless of your new financial reality.
The practical effect: the same person who owes $650 a month for COBRA might qualify for a marketplace plan with a net premium of $200–$350 after subsidy, or even less at lower incomes. When you estimate income for the marketplace, use what you realistically expect to earn this year, including severance and any partial-year wages. To fine-tune the subsidy side of the comparison, the ACA premium subsidy calculator estimates your tax credit from your household income.
A side-by-side over a 6-month gap
Suppose you need six months of coverage between jobs. The table below compares a typical COBRA premium against a subsidized marketplace plan for a single adult whose income dropped after a layoff. Your numbers will differ — run your own in the COBRA vs ACA calculator — but the shape of the answer is common.
| Factor | COBRA | Subsidized ACA plan |
|---|---|---|
| Monthly premium | $650 (full premium + fee) | $300 (after subsidy) |
| 6-month premium total | $3,900 | $1,800 |
| Deductible reset | No — continues current plan | Yes — new plan year starts |
| Network / doctors | Identical to old plan | May differ; check first |
| Enrollment window | 60 days to elect | 60-day SEP |
In this example, the marketplace saves about $2,100 over the six-month gap — real money at exactly the moment your income has dropped. But notice the deductible row: that is where COBRA can quietly win.
When COBRA is still the smarter choice
Cheaper premiums are not the whole story. COBRA can be the better decision in several specific situations:
- You have already met your deductible or out-of-pocket max. A new marketplace plan resets both to zero. If you have already spent thousands hitting your current plan's ceiling this year, switching means paying that again — often erasing the premium savings.
- You are mid-treatment. If you are in the middle of a treatment plan, pregnancy, or a surgery schedule with a specific team, keeping the exact same COBRA plan preserves your doctors and prior authorizations without disruption.
- A specific drug or specialist depends on your network. If a costly medication or a hard-to-find specialist is only well-covered by your current plan, the continuity can be worth the higher premium.
- You expect to be re-employed very soon. For a short one-to-two-month gap, COBRA's paperwork simplicity and retroactive election (you can elect within 60 days and it back-dates) can be convenient.
The right method is to compare premiums first, then adjust for these continuity factors. If the numbers are close, the plan that protects an already-met deductible or an active treatment usually wins.
Frequently asked questions
Is COBRA or ACA marketplace cheaper after a layoff?
For most people a subsidized ACA marketplace plan is significantly cheaper. COBRA charges the full premium your employer used to subsidize, plus up to a 2% fee, often $600–$1,500 a month. Marketplace subsidies rise as your income falls after a job loss, frequently cutting the monthly cost by half or more. COBRA can still win if you have already met your deductible this year.
How long do I have to choose between COBRA and the marketplace?
You generally have 60 days to elect COBRA from the date coverage ends. Losing job-based coverage also triggers a 60-day Special Enrollment Period on the ACA marketplace, so you can enroll in a marketplace plan without waiting for open enrollment. Both clocks start when your coverage ends, so decide before either window closes.
Why does COBRA cost so much more than my paycheck deduction?
While employed, your employer paid most of your premium — often 70% or more — and you only saw a small deduction. COBRA lets the plan bill you the full premium plus up to a 2% administrative fee. The coverage is identical; the entire employer subsidy simply shifts onto you, which is why the price jumps so sharply.
Will I qualify for a marketplace subsidy after losing my job?
Often yes. Premium tax credits are based on your expected annual income, which usually drops after a layoff, so your subsidy typically increases. When you apply, estimate the income you realistically expect for the full year, including severance and any partial wages, rather than entering last year's salary.
When should I keep COBRA instead of switching?
Keep COBRA if you have already met your deductible or out-of-pocket maximum this year, since a new marketplace plan resets both to zero. It is also better if you are mid-treatment with a specific care team, or if a costly drug or specialist is only well-covered by your current network. For very short gaps, COBRA's retroactive election can also be convenient.
Does switching to a marketplace plan reset my deductible?
Yes. A new ACA marketplace plan starts a fresh plan year, so your deductible and out-of-pocket maximum reset to zero. If you have already spent significant money meeting your current plan's ceiling, that reset can outweigh the lower premium — which is exactly when staying on COBRA makes financial sense.
Can I switch from COBRA to a marketplace plan later?
Yes, but timing matters. Voluntarily dropping COBRA does not trigger a Special Enrollment Period, so you generally must wait for open enrollment unless another qualifying event occurs. Exhausting your COBRA coverage does trigger an SEP. Because of this, it is usually best to compare and decide within the initial 60-day window rather than defaulting to COBRA and switching later.
