COBRA vs ACA After a Layoff: Which Is Cheaper?
COBRA feels like the "safe" default because it's automatic. It's rarely the cheapest option. Here's how the two actually compare, and how to decide in about 10 minutes.

⚡ Quick answer
COBRA continues your exact same employer plan, but you pay the full premium plus up to a 2% fee — often $500–$900+/month for one person. Because your household income just dropped, you may now qualify for ACA marketplace subsidies COBRA doesn't offer, which frequently makes a marketplace plan meaningfully cheaper for similar coverage. Compare both before your 60-day window closes.
How COBRA works
COBRA (the Consolidated Omnibus Budget Reconciliation Act) lets you keep your exact employer-sponsored health plan — same doctors, same network, same prescription coverage — for up to 18 months after your job ends (longer in some circumstances). The catch is cost: your employer was likely covering a significant share of the premium while you worked there. Under COBRA, you pay the full premium yourself, plus an administrative fee of up to 2%.
- Election window: 60 days from your coverage end date or from when you receive the COBRA notice, whichever is later.
- Retroactive coverage: If you elect COBRA within the window, coverage is retroactive to the day your employer coverage ended — so there's no actual gap even if you decide a few weeks later.
- Typical cost: Often $500–$900+/month for an individual, and $1,800+/month for family coverage, depending on your previous plan.
How ACA marketplace coverage works
Losing job-based health coverage is a qualifying life event that triggers a 60-day Special Enrollment Period to sign up for an ACA marketplace plan at healthcare.gov (or your state's exchange). Unlike COBRA, marketplace plans are priced based on your estimated income for the year — and that's the detail most people miss.
- Your income likely just dropped, even counting severance and unemployment. Marketplace subsidies are calculated on estimated annual household income, so a lower income after a layoff often unlocks a meaningfully lower premium or a larger tax credit than you'd expect based on your salary before the layoff.
- You choose the plan and network — which means comparing carefully to make sure your current doctors and prescriptions are covered, since marketplace networks can differ from employer plans.
- Coverage starts the first of the month after you enroll, in most cases, so there's no retroactive gap-filling the way there is with COBRA.
Side-by-side comparison
| COBRA | ACA Marketplace |
|---|
| Keeps your exact current plan | Yes | No — new plan selection |
| Typical monthly cost (individual) | $500–$900+ | Often lower after subsidies |
| Subsidy eligible | No | Often yes, post-layoff |
| Enrollment window | 60 days | 60 days |
| Retroactive coverage | Yes | No — starts month after enrollment |
| Pre-existing conditions covered | Yes | Yes |
| Max duration | 18 months (up to 36 in some cases) | Renewable annually |
When COBRA is actually the better choice
Choose COBRA if:
- You're mid-treatment and can't risk a network change
- You've already met a high deductible this year
- Your specific doctors aren't in any available marketplace plan
- Your former employer subsidizes COBRA as part of severance
Choose ACA if:
- Your income dropped enough to qualify for subsidies
- You want a lower monthly premium over network continuity
- You're comparing several plan tiers, not just one option
- Your job search may take several months or more
Mid-deductible-year tipIf you've already paid down a significant chunk of your annual deductible under your employer plan, COBRA lets you keep that progress. Switching to a marketplace plan usually resets your deductible to zero for the new plan year.
When ACA is usually cheaper
For most people who don't have a specific medical reason to stay on their exact old plan, ACA marketplace coverage ends up cheaper after a layoff — sometimes dramatically so. The reason is straightforward: COBRA pricing doesn't change no matter what happens to your income, but ACA subsidies are calculated specifically on your new, lower estimated household income for the year.
If your household income for the rest of the year (severance + unemployment + any part-time income) puts you meaningfully below what it was while employed, it's worth running the numbers on healthcare.gov before defaulting to COBRA — even if COBRA feels like the path of least resistance.

How to decide in 10 minutes
- Find your COBRA premium. It's usually listed on the COBRA election notice, or you can ask HR directly for the exact monthly amount.
- Estimate your household income for the rest of the year — severance, unemployment, any freelance or part-time work, and a spouse's income if applicable.
- Run that estimate through healthcare.gov's plan browser (you can preview plans and subsidy estimates without formally enrolling).
- Check that your must-keep doctors and prescriptions are covered under the marketplace plans you're considering.
- Compare the real monthly cost, side by side, not just the sticker premium — factor in deductibles and out-of-pocket maximums too.
Key deadlines to write down
- 60 days to elect COBRA from your coverage end date or notice date, whichever is later.
- 60 days for your ACA Special Enrollment Period after losing job-based coverage.
- Coverage gap risk: If you miss both windows, you may have to wait for the next open enrollment period, so don't leave this decision for the last week.
Frequently Asked Questions
Is COBRA always more expensive than ACA marketplace plans?
+
Not always, but usually. COBRA requires you to pay the full premium your employer previously subsidized, plus up to a 2% administrative fee, often totaling $500–$900+/month for a single person or $1,800+/month for a family. Because a layoff typically drops your household income, many people qualify for ACA marketplace subsidies that COBRA doesn't offer, which frequently makes marketplace plans cheaper.
How long do I have to decide between COBRA and ACA?
+
You have 60 days from your coverage end date (or from when you receive your COBRA election notice, whichever is later) to elect COBRA. Losing job-based coverage also triggers a 60-day Special Enrollment Period for ACA marketplace plans. Both windows run in parallel, so you have time to compare before choosing.
Can I switch from COBRA to an ACA plan later if I change my mind?
+
Generally no, not until the next open enrollment period or another qualifying life event, unless your COBRA coverage runs out entirely. This is why comparing costs before electing COBRA matters — once you're past your Special Enrollment Period window, switching becomes much harder.
Does COBRA or ACA cover pre-existing conditions?
+
Both do. Under the ACA, marketplace plans cannot deny coverage or charge more for pre-existing conditions, and COBRA continues your exact previous plan with no new waiting periods. Neither option requires medical underwriting.
What if I need to keep seeing a specific doctor mid-treatment?
+
This is one of the strongest reasons to choose COBRA over ACA: it continues your exact same plan and network with no interruption, which matters if you're mid-treatment or don't want to confirm a new marketplace plan includes your specific doctors and facilities.
