COBRA or Marketplace Coverage: Which Should I Choose After Leaving a Job?
Last reviewed: July 2026
When you leave a job, you usually have two main ways to keep health insurance: COBRA, which continues your old employer plan, or a marketplace plan through the Affordable Care Act. COBRA keeps the exact coverage you had but you pay the full premium plus a 2% administrative fee. A marketplace plan often costs less, especially if your income qualifies you for a subsidy, but it may use a different network of doctors. For most people leaving a job in 2026, the cobra vs marketplace decision comes down to three things: whether you qualify for a subsidy, whether you need to keep specific doctors, and how soon you expect new employer coverage.
Key Takeaways
- COBRA lets you keep your exact employer plan, but you pay the full premium plus a 2% fee for up to 18 months.
- Marketplace plans often cost far less when you qualify for premium tax credits based on household income.
- In 2026, a household earning up to 400% of the federal poverty level may still qualify for premium subsidies.
- Losing job-based coverage triggers a 60-day Special Enrollment Period to pick a marketplace plan outside open enrollment.
- COBRA makes the most sense when you are mid-treatment, near a deductible cap, or expect new coverage within weeks.

Leaving a job almost never happens in a vacuum. There's a new job, an early retirement, a layoff, or a business you're starting. The health insurance choice you make in those first 60 days can cost or save you real money, and most people make it under pressure without running the numbers. Let's fix that.
What Is COBRA and How Does It Work?
COBRA is a federal law that lets you keep your former employer's group health plan after you leave, usually for up to 18 months. You get the identical plan, the same network, and the same deductible you already met during the year. The catch is the cost. While employed, your employer covered a large share of the premium. On COBRA, you pay all of it plus a 2% administrative fee.
According to the U.S. Department of Labor, COBRA generally applies to employers with 20 or more employees. Smaller employers may offer similar state continuation coverage, sometimes called mini-COBRA, but the rules vary by state.
The number that surprises people is the real premium. The Kaiser Family Foundation reports that average annual premiums for employer family coverage now exceed $25,000, with workers typically paying only a fraction while employed. On COBRA, you absorb the entire amount. That sticker shock is exactly why running a side-by-side comparison matters before you sign anything.
You have 60 days from losing coverage to elect COBRA, and once you elect it, the coverage is retroactive to the day your job-based plan ended. That retroactive feature is genuinely useful, which we'll come back to.
How Does Marketplace Coverage Work After Leaving a Job?
Marketplace coverage refers to health plans you buy through the Affordable Care Act exchange at HealthCare.gov or your state exchange. Losing job-based coverage is a qualifying life event, which opens a 60-day Special Enrollment Period. During that window you can pick any marketplace plan even though open enrollment is closed.
The big lever here is the premium tax credit. According to HealthCare.gov, subsidies are tied to household income and the cost of a benchmark plan in your area. Many people who assume they earn too much to qualify are wrong, especially in a year when income drops because they left a job. The Centers for Medicare & Medicaid Services confirms that the same Special Enrollment Period applies whether you quit, were laid off, or your hours were cut below the threshold for benefits.
Jeff often tells clients that the marketplace shines when income is going to be lower for the rest of the year. A pre-retiree who steps away mid-year may suddenly look subsidy-eligible on paper, even if their old salary would have disqualified them.
The trade-off is the network. A marketplace plan may not include the same doctors, hospitals, or specialists you used under your employer plan. If you're mid-treatment with a specialist, that matters a great deal.
COBRA vs Marketplace: A Side-by-Side Comparison
Here is the cobra vs marketplace decision laid out across the dimensions that actually drive the choice.
| Dimension | COBRA | Marketplace (ACA) |
|---|---|---|
| Network | Identical to employer plan | May differ; verify your doctors |
| Premium | Full cost plus 2% fee | Often lower with subsidies |
| Subsidy eligibility | None | Yes, based on household income |
| Deductible | Carries over for the plan year | Resets to new plan's deductible |
| Enrollment window | 60 days from coverage loss | 60-day Special Enrollment Period |
| Maximum duration | Up to 18 months (longer in some cases) | Renewable annually |
| Retroactive coverage | Yes, back to coverage loss date | No, future-dated |
The deductible row is the one people miss. If you already paid down a $4,000 deductible by August, COBRA preserves that progress. A new marketplace plan starts your deductible over at zero. For someone with ongoing medical costs, that reset can erase any premium savings.
When Does COBRA Make More Sense Than the Marketplace?
COBRA wins in a handful of specific situations, and they tend to be the ones with the highest stakes. If you're in the middle of treatment with a specific doctor or hospital, COBRA keeps that relationship intact. If you've already met most of your deductible, COBRA preserves it. And if you expect new employer coverage within a few weeks, COBRA's retroactive feature is a safety net.
That retroactive election is an underused move. Because you have 60 days to elect and it backdates to the day you lost coverage, you can go uninsured during a gap, and if you incur a major claim, elect COBRA retroactively to cover it. Jeff calls this the COBRA bridge, and he's used it with clients who started a new job with a short benefits waiting period. You hold off, stay healthy, and never pay the premium unless you actually need it.
This is also where a financial planning process beats picking a plan in isolation. The right insurance choice depends on cash flow, expected income, and what else is happening in your year.

When Is a Marketplace Plan the Better Choice?
A marketplace plan usually wins when your income for the rest of the year qualifies you for a premium tax credit, or when COBRA's full premium simply costs more than a comparable exchange plan. If you're early in the calendar year with a fresh deductible either way, the reset matters less and the lower premium matters more.
Marketplace plans also make sense for self-employment and longer transitions. If you're starting a business or taking an extended break, you may want coverage that renews annually rather than expiring in 18 months. A marketplace plan gives you that continuity. If your wealth is concentrated in a business you're building, coordinating insurance with the rest of your plan gets even more important; see How do I plan for retirement when my wealth is tied up in my business?.
One more point worth checking: an HSA-eligible high-deductible marketplace plan lets you keep contributing to a Health Savings Account, which COBRA may or may not support depending on your old plan. That tax-advantaged savings can be a meaningful benefit. See Should I use my HSA as an investment account?.
Frequently Asked Questions
How long do I have to decide between COBRA and the marketplace?
You have 60 days from the date you lose job-based coverage to elect COBRA, and the same 60-day Special Enrollment Period to choose a marketplace plan. These windows run at the same time, so you can compare both before committing. COBRA's election is retroactive, which gives you extra flexibility within that window.
Is COBRA more expensive than a marketplace plan?
COBRA is usually more expensive because you pay the full premium plus a 2% administrative fee with no subsidy. A marketplace plan can cost far less when your household income qualifies for a premium tax credit. The actual difference depends on your income, your area's benchmark plan, and whether you've already met your deductible this year.
Can I switch from COBRA to a marketplace plan later?
You can switch from COBRA to a marketplace plan, but timing matters. Voluntarily dropping COBRA does not trigger a Special Enrollment Period; you generally must wait for open enrollment or until your COBRA coverage runs out. Exhausting COBRA does qualify as a life event, so plan the transition carefully to avoid a coverage gap.
Do I qualify for a marketplace subsidy if my income was high earlier this year?
Possibly. Premium tax credits are based on your estimated household income for the full coverage year, not just your former salary. If you left a job mid-year and your income will be lower going forward, you may qualify even if your earlier earnings were high. Estimate your full-year income carefully when you apply through HealthCare.gov.
Does my deductible reset if I leave COBRA for a marketplace plan?
Yes. A new marketplace plan starts your deductible and out-of-pocket maximum at zero, even if you already met them under your old employer plan. COBRA preserves the deductible you already paid down for the current plan year. If you have ongoing medical costs, that reset can outweigh any premium savings from switching.
What happens if I have a gap before my new job's insurance starts?
If your new employer has a benefits waiting period, you have options to bridge the gap. COBRA's retroactive election lets you stay uninsured and elect coverage only if a major claim occurs. A short-term marketplace plan is another option. The right choice depends on how long the gap is and your tolerance for risk during that stretch.
Bottom Line: Run the Numbers Before You Default to COBRA
The cobra vs marketplace choice is rarely obvious, and defaulting to COBRA out of habit is how people overpay. Check your subsidy eligibility, confirm your doctors are in-network, and weigh your deductible progress before you commit.
